The Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y) is a niche variant of the more common SM-T580/T585 series. Because it includes S Pen digitizer support, standard ROMs for the "non-S Pen" version (T580/T585) are often incompatible or will break stylus functionality. 🛠️ Essential Pre-Requisites Before starting, ensure you have the following ready: Charge: At least 60% battery. Backup: Move all photos and files to an SD card or cloud.
Unlock Bootloader: Go to Settings > Developer Options and enable OEM Unlock. Driver: Install the Samsung USB Drivers on your PC. Tool: Download Odin3 (v3.13.1 or newer). 💾 Available ROM Options (2026 Status)
Finding a "daily driver" ROM for the SM-P585Y is difficult because of the unique S Pen hardware. Most users choose one of these two paths: 1. Refined Stock (The Reliable Choice)
Most active developers on the XDA Forums for Galaxy Tab A recommend "debloated" stock ROMs. Benefits: Perfect S Pen support and stable LTE/4G. Versions: Most stop at Android 7.0 or 8.1. Best for: Stability and taking notes. 2. LineageOS / GSI (The Modern Choice)
If you want Android 10 or higher, you must use a Generic System Image (GSI).
Warning: S Pen pressure sensitivity often fails, and the camera may be buggy.
Source: Check the GitHub Repository for SM-T585 for compatible kernels that may work with the P585Y. 📝 Step-by-Step Installation Guide Phase 1: Custom Recovery (TWRP) Power off the tablet. Hold Power + Home + Volume Down to enter Download Mode. Connect to PC and open Odin. Put the TWRP .tar file in the AP slot. In Odin "Options," uncheck Auto Reboot.
Hit Start. Once finished, manually reboot into recovery (Power + Home + Volume Up). Phase 2: Flashing the ROM In TWRP, select Wipe > Advanced Wipe. Select Dalvik, System, Data, and Cache. Swipe to wipe. Go to Install and select your Custom ROM zip file. (Optional) Flash GApps (Google Apps) and Magisk (for Root). Reboot System. The first boot can take up to 10 minutes.
💡 Pro Tip: If you find the device too slow, simply Root the stock firmware and use Magisk to remove Samsung bloatware rather than changing the whole OS. If you'd like to proceed, I can help you: Find a direct download link for a specific Android version. Explain how to root without a custom ROM. Troubleshoot "Odin Fail" errors.
The Samsung Galaxy Tab A 10.1 with S Pen (SM-P585Y), released in late 2016, remains a capable device for note-taking and media consumption. However, as official software support has ended, installing a custom ROM is the best way to upgrade to modern Android versions like Android 13 or 14. Why Install a Custom ROM on SM-P585Y?
Modern Software: Transition from outdated Android 8.1 Oreo to newer versions like LineageOS 20 (Android 13).
Performance Boost: Custom ROMs often remove Samsung's "bloatware," leading to smoother UI animations and better battery management.
Security: Gain access to updated security patches that the official firmware no longer provides. Top Custom ROM Options
LineageOS (Unofficial): The most popular choice for the SM-P58x series. Unofficial builds of LineageOS 20 and 21 provide a clean, near-stock Android experience while maintaining S Pen functionality.
/e/OS: A privacy-focused ROM that removes Google services. Recent unofficial builds for the "gtanotexllte" (SM-P585) codename are available for those seeking a "de-Googled" experience.
Project Elixir / DotOS: Occasionally ported by community developers on XDA Forums, these ROMs offer deep visual customization. Essential Prerequisites Before flashing, you must prepare your device and PC:
For the Samsung Galaxy Tab A 10.1 (2016) with S Pen ( ), finding a "good piece" of custom software can be tricky because development is often grouped with its non-S Pen siblings. The SM-P585Y (code name gtanotexllte
) shares much of its hardware with the SM-T585, but specific S Pen functionality often breaks on standard ROMs unless they are explicitly built for the "gtanotexl" variants. Best Custom ROM Options (2025/2026) /e/OS (Unofficial Builds)
: This is currently one of the most active projects for this device family. It focuses on privacy and de-Googling. Recent unofficial builds for the have been reported as smooth, though some users on the e/OS Community forum noted potential Wi-Fi stability issues. LineageOS 20 (Android 13)
: While official support is rare for this model, unofficial LineageOS builds are the go-to for "reviving" the tablet. These ROMs can update the device from its final official Android 8.1 version to much newer Android versions, allowing for better app compatibility. GSI (Generic System Images)
: Since this tablet supports Project Treble (if updated to later stock versions), you can technically flash GSIs like
(Android 14). However, GSIs are often prone to bugs with specific hardware like the camera or Bluetooth on older Samsung devices. Key Considerations Before Flashing S Pen Support
: Most generic ROMs (LineageOS, etc.) will treat the S Pen as a basic stylus. You will likely lose "Air Command" and specific Samsung Note features unless you use a TouchWiz-based custom ROM. Performance : Custom ROMs typically improve speed by removing background bloatware and using a more lightweight system UI. Installation : You will need a custom recovery like

For the Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y), custom ROMs are the primary way to bypass the official "end-of-life" software (Android 8.1) and run modern apps in 2026. Performance & Stability Review
System Speed: Users report significant performance gains compared to the bloated stock Samsung Experience. Modern lightweight ROMs like LineageOS resolve multitasking issues where background apps would previously close prematurely.
App Compatibility: Installing Android 13 or 14-based ROMs allows the tablet to run the latest versions of apps from the Google Play Store, which are otherwise restricted on the tablet's native Android 8.
Battery Life: Optimized custom kernels often included in these ROMs provide better idle battery drain and thermal management compared to the aging official firmware.
S-Pen Functionality: While basic S-Pen input (drawing/writing) works on most AOSP-based ROMs, specialized Samsung-specific features like "Air Command" are typically lost. You may need third-party apps to replicate the advanced pen menus. Top Custom ROM Options (2026)
The development for this device (codename: gtanotexllte) is often bundled with its Wi-Fi sibling (gtanotexlwifi) and the non-S-Pen variant (gtaxllte).
LineageOS 20 (Android 13): Currently the most stable and popular choice. It provides a "near-vanilla" Android experience that is highly responsive on the tablet’s Exynos 7870 chipset.
LineageOS 19.1 (Android 12): A rock-solid alternative if you encounter bugs on newer versions. It is praised for fixing the multitasking bugs found in earlier unofficial builds.
crDroid (Android 14/GSI): For users wanting the absolute latest Android version, GSI (Generic System Image) builds of crDroid offer deep customization, though they may require more manual troubleshooting. Critical Installation Notes
Custom Recovery: You must first install TWRP for SM-P585Y to flash any custom ROM.
Google Apps (GApps): Most ROMs come "vanilla." You need to flash a GApps package (like NikGApps or MindTheGapps) separately to get the Play Store.
Bootloader: Ensure your bootloader is unlocked. Attempts to flash on a locked bootloader will result in a "Secure Check Fail" error.

The Samsung Galaxy Tab A 10.1 (2016) with S Pen, model number SM-P585Y, holds a unique place in the Android tablet ecosystem. Released as a budget-friendly alternative to the Galaxy Tab S series, it was one of the few mid-range tablets to include Samsung’s signature S Pen support.
However, as the device ages and official software support has long ended (it launched with Android 6.0 Marshmallow and officially stopped at Android 8.1 Oreo), many users turn to Custom ROMs to breathe new life into the hardware.
HOME_CSC to keep data)Introduction: Breathing New Life into an Old Favorite
The Samsung Galaxy Tab A 10.1 (2016) with model number SM-P585Y is a device that holds a special place in the hearts of many Android tablet users. Launched with Android 6.0 Marshmallow and officially updated only to Android 8.1 Oreo, this once-mighty mid-ranger—featuring an S-Pen, 4G LTE connectivity, and a crisp 1920x1200 display—has long been abandoned by Samsung in terms of software updates.
For the average user, an Android 8.1 tablet in 2025 feels archaic. Apps crash, security patches are years out of date, and the user interface lags behind modern standards. However, for the tech-savvy user, the SM-P585Y represents a golden opportunity. This is where SM-P585Y custom ROMs come into play.
Installing a custom ROM is like performing a heart transplant on your tablet. It replaces the old, bloated Samsung TouchWiz (or Samsung Experience) UI with a clean, fast, and modern version of Android. In this guide, we will explore everything you need to know—from the benefits and risks to the step-by-step process and the best ROMs available for this specific model.
Stability: 10/10 Best for: Users who want the most stable experience.
While Android 11 is older, the Havoc-OS build for SM-P585Y is rock solid. It includes a gaming mode, screen recording, and excellent thermal management. If you primarily use the tablet for media consumption and emulation (PSP, N64, DS), this is the best choice.
I. Context and Intent A developer with a Samsung Galaxy Tab Pro 10.1 (SM‑P585Y) decides to replace the stock firmware with a custom ROM to gain a leaner system, longer security maintenance, and granular control over performance and privacy settings. Their goals: a reliable daily driver, stable cellular modem, functional GPS, and minimal battery drain.

For the Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y), moving to a custom ROM can breathe new life into a device that officially stopped at Android 8.1 Oreo. Available Custom ROMs
While this specific LTE variant (codename gtanotexllte) has slightly less traffic than its Wi-Fi counterpart (SM-P580), there are active community projects:
LineageOS: Unofficial builds of LineageOS 19.1 (Android 12) and LineageOS 20 (Android 13) have been developed for the gtanotexllte/gtanotexlwifi series. These provide a clean, "stock-like" experience and better performance than Samsung’s original One UI.
e/OS: Unofficial builds based on Android 12 (S) are also available, focusing on privacy and de-Googling.
GSI (Generic System Images): As a last resort, some users have successfully flashed GSIs like crDroid (Android 14) using TWRP, though stability can vary greatly on older hardware. Key Considerations Before Flashing
S Pen Functionality: Most AOSP-based ROMs (like LineageOS) support basic S Pen input, but you will lose Samsung-specific S Pen features like "Air Command" and specialized note-taking apps unless you use third-party alternatives from the Play Store.
Knox & Security: Unlocking the bootloader permanently trips Knox. This disables features like Samsung Pay and Secure Folder forever.
VoLTE Issues: A common bug with Exynos-based Samsung custom ROMs is the lack of VoLTE support. This means you may be able to use LTE for data, but traditional voice calls might not work if your carrier requires VoLTE. Quick Setup Steps
This is the story of "The Phoenix Tablet"—a tale of a forgotten Samsung Galaxy Tab A 10.1 (SM-P585Y)
and the digital alchemist determined to give it a second life.
sat in the back of Elias’s desk drawer, a thin layer of dust coating its screen. In its prime, it was a workhorse—the rare "with S-Pen" variant that Elias used to sketch architectural designs and manage emails while traveling. But time is a cruel master to mobile hardware. Stuck on an aging version of Android, the once-snappy tablet had become a sluggish relic, stuttering through basic apps and losing support for modern security patches.
"One last try," Elias muttered, pulling the tablet from the drawer. He didn't want to buy a new one; the hardware was still solid, the screen vibrant, and the S-Pen felt just as natural as ever. He needed a Custom ROM. The Descent into the Forums
Elias began his journey where all such stories start: the dimly lit digital corridors of XDA Developers. He searched for " ," the specific LTE variant of the Tab A with the stylus.
He found a community of enthusiasts who refused to let their hardware die. They spoke in the language of bootloaders, kernels, and recovery images. He learned that the first step wasn't the software itself, but the "gatekeeper"—TWRP (Team Win Recovery Project). The Ritual of Flashing
With a deep breath, Elias connected the tablet to his PC. He put the device into Download Mode, the screen turning a bright, clinical teal.
Unlocking the Gate: He used Odin on his computer to flash the TWRP recovery. One wrong move here could "brick" the device, turning his tablet into a very expensive paperweight. The progress bar crawled... Pass!
The Clean Slate: Entering the new TWRP recovery menu, he performed a "Full Wipe." He watched as the old, bloated Samsung software was scrubbed away.
The Incantation: He selected the Custom ROM file he had downloaded—a version of LineageOS (or perhaps a refined Project Elixir port). He swiped the slider to "Flash."
Lines of white text scrolled across the black screen like falling rain in The Matrix. He also flashed a "GApps" package, the secret sauce that would bring the Google Play Store back to life. The Rebirth
The tablet vibrated. The screen went black, then the new boot animation appeared—not the familiar Samsung logo, but a pulsing, minimalist loop. It stayed there for minutes. The "Bootloop" anxiety set in. Then, suddenly, the "Welcome" screen appeared.
Elias navigated the setup. The tablet was unrecognizable. The heavy "TouchWiz" skin was gone, replaced by the clean, airy aesthetic of near-stock Android. It was fast. Apps that used to take five seconds to open now snapped into view instantly. The S-Pen's New Soul
The biggest worry was the S-Pen. Would it still work? Elias pulled the stylus from its slot. A small cursor appeared on the screen, following the tip perfectly. While he lost some of the proprietary Samsung "Air Command" menus, he gained a device that felt five years younger and was secured against modern threats.
wasn't just a tablet anymore; it was a testament to the power of the open-source community. Elias put it back on his desk—not in the drawer, but right next to his laptop, ready to work.
, or are you interested in which ROMs are currently the most stable for that model?
The year was 2024, and the Samsung Galaxy Tab A 10.1 (2016) with S Pen, model number SM-P585Y, was not aging gracefully.
For its owner, Elias, the tablet had become a test of patience. Once a capable digital canvas, it now wheezed under the weight of modern apps. The S Pen, still physically perfect, felt sluggish on the screen because the processor was throttling, trying to manage the bloated factory software. The final straw came when Elias tried to open a PDF for a work meeting, and the tablet simply stared back at him for forty-five seconds before crashing to the home screen. The Samsung Galaxy Tab A 10
"Junk," Elias muttered, tossing it onto the couch. He reached for his laptop to order a new iPad.
But then, he paused. He remembered the old mantra of the tech forums: Hardware doesn’t die; software kills it.
He picked up the tablet again. The screen was still beautiful. The Wacom digitizer layer for the S Pen was a feature you couldn't find on cheap tablets anymore. It was too good to throw away.
Elias opened his laptop and typed the incantation: sm-p585y custom rom.
The search results were a digital wasteland. "Bootloop," "Bricked," "Error 7." The SM-P585Y was the weird Australian/New Zealand variant. It wasn't the popular LTE version sold in Europe; it was specific, finicky, and largely abandoned by the developer community years ago.
After an hour of digging through the archives of XDA Developers, he found a single thread from three years ago. The developer, a user named PhantomCoder, had ported a version of LineageOS (Android 11) specifically for this obscure model. The thread was full of people thanking him for bringing the dead back to life.
"Let's do it," Elias whispered.
The process was a high-wire act. He installed Odin, the Samsung flashing tool, which looked like a piece of software from the Windows 95 era. He hunted down the exact TWRP recovery image—a custom boot environment required to install the new software. He had to uncheck a box labeled "Flash Lock" that forum veterans warned would permanently brick the device if touched.
He connected the tablet to the PC. The Odin interface turned blue. Connected.
He hit start. A green progress bar crawled across the screen. The tablet rebooted into a black screen with white text.
Success.
But they weren't done. He now had the recovery tool, but no operating system. He copied the LineageOS ZIP file and a separate ZIP for Google Apps onto an SD card—since the internal storage was currently a blank slate.
He booted into TWRP. The touch interface was jittery, but functional. He selected Wipe, then Install. He navigated to the SD card.
The installation bar moved. "Updating system files..." "Installing boot image..."
The tablet rebooted. The screen went black. Elias waited. One minute. Two minutes. The fear of the "bootloop" crept in. Had he just turned the device into a paperweight?
Then, the screen flickered.
A bright, clean boot animation appeared. It wasn't the loud, neon Samsung logo. It was the sleek, cyan circle of LineageOS.
The lock screen appeared. It was fast. Incredibly fast. The animations were snappy, devoid of the heavy TouchWiz lag that had plagued the device for years.
Elias tapped the screen, pulled the S Pen from its slot, and opened a note-taking app. The lines appeared on the screen instantly—zero latency. He opened Chrome; it loaded in a second. He opened YouTube; it played smoothly without stuttering.
The Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y) can be updated far beyond its final official Android 8.1 software using custom ROMs. While official support from major projects like LineageOS is limited, unofficial builds and Generic System Images (GSIs) allow you to run versions as high as Android 14. 1.

Breathing New Life into Your Samsung Galaxy Tab A 10.1 (2016) with S Pen: The SM-P585Y Custom ROM Guide
The Samsung Galaxy Tab A 10.1 (2016) with S Pen (SM-P585Y) remains a beloved device for students, digital artists, and note-takers. However, being stuck on older versions of Android can lead to sluggish performance and limited app compatibility. Fortunately, the developer community has kept this hardware relevant through custom ROMs.
If you're looking to upgrade your tablet, this guide covers everything you need to know about finding and installing an SM-P585Y custom ROM. Why Install a Custom ROM on the SM-P585Y?
While Samsung’s official software was stable, it eventually became "bloated" and outdated. Here is why users switch to custom software:
Updated Android Versions: Experience Android 10, 11, or even 12 features on hardware that officially stopped at Android 8.1 (Oreo).
Performance Boost: Custom ROMs like LineageOS are often lighter, freeing up RAM and improving multitasking.
Privacy and Security: Get the latest security patches that Samsung no longer provides. SM-P585Y Custom ROM Guide: Reviving the Galaxy Tab
De-bloating: Remove pre-installed apps that take up valuable storage space. Top Custom ROM Options for SM-P585Y
The SM-P585Y shares much of its DNA with the SM-P580 (Wi-Fi version) and SM-T580/T585, but because it has an LTE modem and S Pen, you must ensure the ROM specifically supports the "gtanotexllte" (the codename for the SM-P585 series). 1. LineageOS (Unofficial)
LineageOS is the gold standard for custom ROMs. It offers a "Stock Android" experience with deep customization options. For the SM-P585Y, look for builds that maintain S Pen functionality and LTE connectivity. 2. Resurrection Remix
If you want every possible customization setting—from lock screen tweaks to status bar icons—Resurrection Remix is often the go-to. It combines features from LineageOS, SlimROM, and OmniROM. 3. CrDroid
CrDroid is highly recommended for those who want a balance between performance and features. It is known for being snappy and having excellent battery management for the Exynos 7870 chipset found in the SM-P585Y. Prerequisites Before Flashing
Flashing a ROM is a technical process. Ensure you have the following:
Backup: Custom ROM installation requires a full data wipe. Back up your photos, documents, and contacts.
Unlocked Bootloader: Samsung devices usually require "OEM Unlocking" to be enabled in Developer Options.
Custom Recovery: You must have TWRP (Team Win Recovery Project) installed.
Battery Charge: Ensure your tablet is at least 60% charged to prevent shutdown during the process. Step-by-Step Installation Guide Step 1: Unlock Developer Options
Go to Settings > About Tablet > Software Information and tap "Build Number" seven times. Then, go back to Settings, enter Developer Options, and toggle on USB Debugging and OEM Unlocking. Step 2: Install TWRP Recovery
Using a PC and a tool called Odin, flash the correct TWRP .tar file for the SM-P585Y.
Boot the tablet into Download Mode (Power + Home + Volume Down). Connect to Odin and place the TWRP file in the AP slot. Click Start. Step 3: Flash the Custom ROM
Download your chosen ROM (and the corresponding GApps if you want Google Play Store) and move them to your tablet's internal storage or SD card. Boot into TWRP (Power + Home + Volume Up).
Go to Wipe > Advanced Wipe and select System, Data, Cache, and Dalvik.
Go to Install, select your ROM zip file, and swipe to flash. (Optional) Flash the GApps zip file immediately after. Reboot System. A Note on the S Pen
One of the biggest concerns for SM-P585Y users is the S Pen. While basic stylus input works on almost all custom ROMs, the "Air Command" menu is a proprietary Samsung feature. To keep these features, look for "TouchWiz-based" custom ROMs or use third-party apps like Squid or Notehelf to replicate the note-taking experience on AOSP-based ROMs. Conclusion
Installing a custom ROM on your SM-P585Y can make a 2016 tablet feel like a modern 2024 device. By moving away from older software, you unlock better speeds, newer apps, and a cleaner interface.
Disclaimer: Modifying your device software carries risks and will void your warranty. Proceed with caution and follow developer instructions on forums like XDA-Developers closely.
