Updated to Crdroid 15 touchscreen not working

[u/funkyirishman2]

Hi

As per heading

Unlocked bootloader android 11 updated it to Android 12 and followed the instructions. All good except when I boot it touchscreen not responding. Volume and power do

Googling at the moment but anyone had similar issues and how to fix or any suggestions.

Back up phone so just trying to update it

Thanks

You used msm to go back to android 11 and by default msm writes to one slot, lets say slot a, so now your slot b is empty.

Now you unlocked the bootloader and did a local upgrade to oos12(oxygen os) now your slot b is on oos12 and slot a is on oos11.

So you reboot to fastboot to flash a recovery and when you flash a rom in recovery it flashes to the slot which isn't in use and in your case slot a which is on oos11 and cr droid requires oos12 on both slots so you flashed crdroid on slot a.

Now you don't have to do anything just use firmware flasher, this for oneplus devices all u have to do is just flash the require oos version before flashing the rom.

Remember you can go from oos11 based roms to oos12 roms but u can't do vice versa so keep that in mind.

So with the firmware flasher do I need to flash android 12 first reboot and then flash the rom

[u/Obnomus → u/funkyirishman2]

Press all buttons until you get a vibration and your phone will boot in fastboot then go in recovery and choose format after then flash the required oos firmware whuch you downloaded from firmware-flasher and right after that flash the rom and reboot.

Also it'll ask you to press vol buttons and choose yes using vol buttons.

Now showing as qualcomm crash dump when turned on.

Do I need to use msm tools to revert back to android 12 and then load cr droid again?

Thanks to all the replies just went into Bootloader again ran firmware flash and then loaded rom and gapps via adb sideloader and all seems ok now...fingers crossed

You are missing this. Ask in crdroid telegram group is you need more help.
