3. Available Custom ROMs for Vivo 1801

The community is small, but here’s what exists (mostly on 4PDA, XDA, and Telegram):

| ROM Name | Android | Stability | Bugs | Best for | |----------|---------|-----------|------|-----------| | LineageOS 18.1 | 11 | Medium | Camera (GCam works), VoLTE dead, flashlight delay | Daily driver (if no calls needed) | | Pixel Experience 11 | 11 | Low | RIL drops, Bluetooth audio stutter | Tinkerers | | crDroid 7.x | 11 | Medium | Same as LOS + random reboots | Customization lovers | | AncientOS | 12L | Low | Hotplug broken, battery drain | Aesthetics | | GSI (AOSP 13) | 13 | Unstable | RIL, WiFi MAC random, no deep sleep | Testing only |

No Android 14/15 ROMs – Kernel 4.4 is too old. No one backported the necessary drivers.

Is It Worth It? – The Final Verdict

Yes, but only if you are an enthusiast.

If you want a stable phone for calls, WhatsApp, and light social media: Stick with stock Funtouch OS. The bugs on custom ROMs (especially VoLTE) will frustrate you.
If you want to experiment, learn, and don’t need VoLTE: Installing a LineageOS 20 GSI turns the Vivo 1801 into a surprisingly capable Android 13 device. It feels faster, cleaner, and more modern than Vivo ever intended.

Introduction: The Forgotten Mid-Ranger

In the sprawling ecosystem of Android smartphones, few devices age as rapidly as mid-range contenders released between 2017 and 2019. The vivo 1801, known in various markets as the vivo V11 or V11i, stands as a quintessential example of this era. Launched with a shimmering gradient plastic body, a pioneering in-display fingerprint scanner, and MediaTek silicon, it was a device that promised the future but was quickly left behind by official software support.

For the power user holding onto this device today, the stock firmware is a digital fossil—buggy, bloated, and stuck on aging Android versions. This creates a compelling case for the custom ROM scene. However, flashing a custom ROM on the vivo 1801 is not a journey for the faint of heart. It is a technical labyrinth involving proprietary tools, disclaimers, and the unique challenges of MediaTek (MTK) architecture.

This article explores the current state, technical hurdles, and available options for breathing new life into the vivo 1801.

Challenges: The Bootloader Lock

Vivo is notorious for locking bootloaders tightly. Unlike Xiaomi or OnePlus, Vivo does not provide an official bootloader unlock tool for the 1801. This is the biggest hurdle.

To install a custom ROM on the Vivo 1801, you typically need to use:

MTK Client: An exploit-based tool to bypass authentication.
SP Flash Tool: For flashing pre-loader files.
Test Point Method (sometimes): Shorting specific pins on the motherboard to force the device into BROM mode.

Note: If your Vivo 1801 is running the very latest security patch, unlocking may be impossible. Community support suggests that units on firmware version PD1801F_EX_A_2.8.0 or lower are easier to unlock.
