How To Guide FIX OTA installation problem

[Nayakantipavankumar]

hi mates,
recently when i downgraded from Nos 13 to 12 (or) from custom to stock NOS i had faced OTA installation problem
(note im bootloader and critical unlocked)

OTA update use fail , and local update also getting error.

I fixed the issue by

1. fastboot flash boot boot.img
2. fastboot flash vendor_boot vendor_boot.img
3. fastboot reboot recovery
4. then select apply update -> adb side load option in recovery
5. adb sideload <full_Nos_rom_zip_filename> (from pc)
6. comeback in recovery and perform factory data reset
7. reboot system

note:
use payload dumper method to get boot and vendor_boot of specific version that you are using. using other version might cause brick.
use the boot and vendor images for same Nos version
1.1.3 full rom , 1.1.3 boot , 1.1.3 vendor_boot
(or)
1.1.7 full rom , 1.1.7 boot , 1.1.7 vendor_boot

when i tried to use 1.1.4 rom files i got error of previous installation failed in recovery but when i tried with 1.1.3 then succeeded. so try with 1.1.3 or 1.1.7 files.

after reboot now OTA has worked, and now im in 1.1.8

note: i had not locked bootloader and critical at any point. OTA will worked even bootloader is unlocked.

Yes, but it's not new and logical. You redo a clean installation for have a stable base like users don't have OTA issue. So there no true way to force / fix OTA install in your steps because you must (in this case) entirely factory reset.

It's important to add a thing, factory reset only from actual firmware with OTA issue don't working.
Only factory reset with the boot/vendor_boot replacement working.

I have tried this method but get an error when trying to sideload in recovery. Every method I have tried stop the ability to update via OTA or through recovery.
