Pre-Requirements:

Download Rollback Package

Download links for OnePlus rollback packages:

Now that you have downloaded the rollback package from the above section, create a complete device backup before proceeding with the below-mentioned steps. This is because the installation steps require a wipe of the data. Once you have done so, here is everything you need to be aware of regarding the downgrade of the OnePlus 10R 5G from Android 13 to Android 12.

Downgrade Instructions

  1. First of all, Turn off your device.
  2. Now reboot your phone into bootloader mode by pressing and holding the VOLUME UP and POWER buttons simultaneously.
  3. Now connect your device to your PC using the USB cable.
  4. Open the extracted firmware folder to flash it using fastboot mode.
  5. Enter the below code to boot your device into fastbootd mode.
fastboot -w

3. Now flash the following files by entering the code

fastboot flash boot boot.img
fastboot flash cpucp cpucp.img
fastboot flash dtbo dtbo.img
fastboot flash modem modem.img
fastboot flash oplusstanvbk oplusstanvbk.img
fastboot flash oplus_sec oplus_sec.img
fastboot flash qweslicstore qweslicstore.img
fastboot flash shrm shrm.img
fastboot flash splash splash.img
fastboot flash vbmeta vbmeta.img
fastboot flash vbmeta_vendor vbmeta_vendor.img
fastboot flash vbmeta_system vbmeta_system.img
fastboot flash vendor_boot vendor_boot.img
fastboot flash vm-bootsys vm-bootsys.img

4. Now reboot into userspace fastboot, aka fastbootd. If you don’t do this, the remaining files cannot be flashed:

fastboot reboot fastboot

5. Flash the remaining files:

fastboot flash abl abl.img
fastboot flash aop aop.img
fastboot flash bluetooth bluetooth.img
fastboot flash devcfg devcfg.img
fastboot flash dsp dsp.img
fastboot flash featenabler featenabler.img
fastboot flash hyp hyp.img
fastboot flash imagefv imagefv.img
fastboot flash keymaster keymaster.img
fastboot flash multiimgoem multiimgoem.img
fastboot flash qupfw qupfw.img

fastboot flash xbl_config xbl_config.img
fastboot flash product product.img
fastboot flash system system.img
fastboot flash system_ext system_ext.img
fastboot flash vendor vendor.img
fastboot flash odm odm.img

6. Now reboot your device into the system using the below fastboot command:

fastboot reboot

7. If everything worked, your phone should now boot into OxygenOS.
The files will be flashed to your currently active boot slot. If any of them fail to flash, switch to the other slot and start over from the beginning. I couldn’t flash odm, product, system, system_ext, and vendor to slot a, and had to use slot b instead. To check the current slot:

fastboot getvar current-slot

To switch slots:

fastboot --set-active=a

or

fastboot --set-active=b
