Hi! I can't update to F17. This are my steps:
Restore image from magisk
Donwload Ota and let extract
Install magisk again on inactive slot
The device reboots in qualcom dump mode, so I have to reboot again and they it starts
But at this point I lost root and it says update failed
Anyway I'm able to regain root flashing magisk via twrp
What I'm doing wrong
Download OTA to Device.
Reboot to Recovery TWRP
Install OTA with TWRP
Install Magisk with TWRP
Check Magisk with Magisk App.
This was the old way in older versions of Android prior to Android 11.
I think it still works.
I have an unlocked bootloader, TWRP Recovery and Magisk systemless root.
I think what everyone is doing for OOS13 Incremental OTA is this :
Download and install the System Updater apk from Oneplus.
Use Oxygen Updater to download Incremental OTA Update.
Run System Updater to install Incremental OTA update.
DO NOT REBOOT.
Close System Updater.
Install Magisk to Inactive Slot.
