Instructions to flash PixelOS Android 12/12.1 on Redmi Note 10

Notes:

• The system may take up to 15 minutes to boot up. [Yes it takes a while even on Redmi Logo]
• Remove the sim card tray for the first boot. [If it takes very long to boot]
• Appropriate recovery for the build is <filename of ROM>_recovery.img

Method 1: Through PixelOS Recovery [Recommended]

1. Download ROM and Recovery to your computer
2. Reboot the device to bootloader (Fastboot Mode)
3. Flash the recovery by running "fastboot flash boot <path/to/recovery.img>"
4. Reboot to recovery by running "fastboot reboot recovery"
5. On your phone [which is in recovery mode], Apply update > Apply from ADB
6. Flash the ROM through ADB sideload "adb sideload <path/to/rom.zip>"
7. Once it finishes installing, go back to main menu > Factory reset > Format data/factory reset > Format data > Back to Main menu > Reboot to system
8. It should boot to PixelOS Android 12

Notes:

• If it does not flash through adb sideload, and throws error like "Error applying update: 7 (ErrorCode::kInstallDeviceOpenError:Error in /sideload/package.zip (status 1)" flash Fastboot ROM using MiFlash
• Try out Method 2 if this fails due to any other reason

Method 2: Through Custom Recovery

Thanks to @NextZen86 for sharing

1. Flash Ofox in TWRP (Note: If you already have Ofox installed ignore this step)

2. Format Data, Switch Slot, and Flash ROM

3. Reflash Ofox or install TWRP instead in ramdisk [OPTIONAL]

4. Reboot recovery

5. Reboot system

7. If it didn't boot, reflash ROM in OrangeFox, but don't switch slot this time.

8. Format Data

9. Redo step 3 if you want to keep the custom recovery

10. Reboot system

Notes:

• If it does not flash through adb sideload, and throws error like "Error applying update: 7 (ErrorCode::kInstallDeviceOpenError:Error in /sideload/package.zip (status 1)" flash Fastboot ROM using MiFlash
• Try out Method 3 if this fails due to any other reason

Method 3: Using Fastboot OTA Tool

1. Download the ROM.zip to your Computer
2. Download the Fastboot OTA Tool from the link given above
3. Extract the Fastboot OTA Tool to a new folder, there should not be anything else in the same folder.
4. Copy/Cut the ROM.zip and paste it in the root directory
5. Run the appropriate script based on your Operating System, ie flash_windows.bat for Windows, flash_mac for Mac and flash_linux for Linux.
6. Once you are instructed to connect the phone in Fastboot mode to the PC by the script, do so.
7. Wait for the script to complete
8. Once it completes successfully, you will be rebooted to LineageOS Recovery
9. Format Data from there if needed, else reboot to system
10. You should boot to the system
