Factory Reset Protection (FRP) on devices powered by the Allwinner A133
quad-core processor is a security feature designed to prevent unauthorized access after a hard reset. When a device is reset through recovery mode without first removing the linked Google account, it will require those original credentials to complete the setup process. Common Bypass Methods for Allwinner A133
Bypassing FRP on Allwinner A133 devices (commonly found in budget or "China" tablets) often involves using specific service tools or exploiting system vulnerabilities. How to Use & Remove Android FRP (Factory Reset Protection)
Allwinner A133 is a popular quad-core 64-bit chipset frequently found in budget tablets from brands like Onn, Alldocube, and various generic Android manufacturers
. While these devices provide great value, users often encounter the Factory Reset Protection (FRP)
lock after performing a hard reset without removing their Google account first.
This article provides a comprehensive overview of how to manage and bypass the FRP lock on Allwinner A133 devices. What is Allwinner A133 FRP?
Factory Reset Protection (FRP) is a security feature built into Android (typically version 5.1 and higher). When you reset an Allwinner A133 tablet through recovery mode, the device "locks" itself and requires the login credentials of the Google account previously synced to the device. This prevents unauthorized users from using the tablet if it is stolen or lost. Allwinner A133 Frp
Method 1: The "No-Tool" Manual Bypass (Google Keyboard/Settings)
For many Allwinner A133 tablets running Android 10 or 11, you can often bypass the lock by exploiting gaps in the setup wizard's accessibility or keyboard settings. Connect to Wi-Fi: Power on the device and connect to a stable Wi-Fi network. Access Keyboard Settings:
Go back to the "Connect to Wi-Fi" screen. Tap on "Add New Network" to bring up the keyboard. Enter Settings: Settings/Gear icon on the keyboard (or long-press the comma/space bar). Help & Feedback:
Navigate to the "Help & Feedback" section within the keyboard menu. Launch Browser:
Search for a term like "Use Morse Code" or "About Switch Access for Android." Tap on any result that features a YouTube video embed. Open Chrome:
Tap the video title to open the YouTube app, then tap the User icon -> Settings -> About -> Google Privacy Policy . This will launch the Chrome browser. Bypass Apps: Search for a bypass website (like Set New Pattern:
Use the "Open Screen Smartlock" or "Open Settings" link. If you can access settings, try to set a new Screen Lock (Pattern or PIN)
Once a new lock is set, restart the tablet and use that PIN/Pattern to complete the setup. Method 2: Using Professional Flash Tools (PhoenixUSBPro)
Since the A133 is an Allwinner chipset, you can use official flashing tools to reset the device partitions entirely. PhoenixUSBPro or PhoenixCard. You must have the specific Stock ROM (.img file) for your exact tablet model. Load the firmware into PhoenixUSBPro. Put the tablet into (usually by holding Volume Up while connecting to a PC).
The tool will recognize the device and allow you to "Burn" the firmware, which wipes the FRP partition along with the user data. Method 3: ADB/Fastboot (For Advanced Users)
If the device has USB Debugging enabled (unlikely after a fresh reset, but possible on some developer units), you can use ADB commands: Allwinner A133 FRP Report Introduction The Allwinner A133
adb shell content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1 Use code with caution. Copied to clipboard Alternatively, in Fastboot mode: fastboot erase config fastboot erase frp Use code with caution. Copied to clipboard Important Safety Considerations Data Loss:
These methods will permanently erase all data on the device. Verification:
Only use these methods on devices you legally own. Bypassing security on stolen property is illegal. Firmware Matching:
If using Method 2, ensure the firmware matches your build number exactly. Using the wrong firmware can "brick" the Allwinner A133 chip, rendering the device unbootable.

Method 2: Google TalkBack & Voice Assistant (Android 11+)
Newer Allwinner A133 tablets running Android 11 or 12 have patched the Settings Crash method. However, the TalkBack exploit remains viable.
Procedure:
- On the language selection screen, place two fingers on the screen and hold them for 5 seconds. This activates TalkBack.
- Draw an "L" shape on the screen to open the TalkBack controls.
- Navigate to TalkBack Settings (look at the screen and tap once to highlight, then double-tap to select).
- Scroll down to "Gesture Tutorial" and double-tap it.
- Once inside the tutorial, use a two-finger swipe up to open the notification shade.
- Tap (with double-tap) the Settings gear icon.
- Search for "Accessibility" → "Installed services".
- Turn off TalkBack.
- You are now inside the tablet settings. Go to Accounts → Google → Remove account. Then perform a full factory reset from the System → Reset menu.
Note: This method fails if the manufacturer has disabled the gesture tutorial.
Recommended For Users / Repair Technicians
- Keep Google account credentials backed up; enable account recovery options.
- Before selling or handing off a device, perform a factory reset only after removing linked accounts (Settings → Accounts → Remove).
- For lost-account recovery, use account recovery tools from the account provider before attempting bypasses.
- For legitimate repairs requiring FRP removal, obtain proof of ownership; prefer official service centers to avoid warranty/legality issues.
The Allwinner A133 twist
Unlike Qualcomm or MediaTek chips, the A133 has a peculiar burned-in USB vendor mode (usb_gadget) active even before Android fully boots. During early boot stages, the chip exposes a raw diagnostic interface via VID_1f3a_PID_1330. This mode bypasses Android’s normal USB restrictions — including FRP’s lock on host-based interactions.
Here’s the magic: With the right Allwinner PhoenixUSB protocol command, you can send a specific USB control transfer that triggers FRP_RESET in the secure storage partition — not the Android userspace. Why does this work? Because the A133’s Trusted Execution Environment (TEE) accepts certain diagnostic commands when the device is in “preloader mode,” regardless of FRP status. Essentially, Allwinner left a debug door open. Using the Allwinner FRP Tool : A specialized
