Hey there all,
I have a OnePlus 5 which is already rooted and has TWRP from here ( sourceforge [dot] net/projects/cheeseburgerdumplings/files/15.1/cheeseburger/recovery/twrp-3.2.3-0-20180822-codeworkx-cheeseburger.img/download ) which works. I have OOS 5.1.5, magisk manager and magisk root, OEM bootloader unlocked, basically, all required stuff for root.
I want to update to Android Pie (OOS 9.0.4) but when flashing either TWRP from here ( sourceforge [dot] net/projects/cheeseburgerdumplings/files/16.0/cheeseburger/recovery/twrp-3.2.3-0-20190311-codeworkx-cheeseburger.img/download ) or here ( github [dot] com/engstk/android_device_oneplus_cheeseburger/releases/tag/v9.96 ) by booting into fastboot, then doing:
(or other image name)
and then booting recovery.. first oneplus logo, then black screen and white led. On both TWRP's.
So I reboot back into fastboot, flash the android 8.1 TWRP and I can boot into TWRP, but the 8.1 TWRP cannot flash OOS 9.0.4 (error 7), so I need to flash TWRP for android 9, but that TWRP won't boot.
How can I proceed? (without deleting my data/apps, and yes I did make a tar of /data and a TWRP backup of the phone). I know upgrading without wipe *should* possible as I've upgraded from 7/nougat to 8.1/oreo this way (flashing 8.1 twrp, flashing oos 5 zip, wiping cache, reboot - worked fine).
