[hypergamer1231]

Hello friends,

After trying different roms and kernels there always comes a time when we wish to go back to complete stock for a smooth reliable experience. Here's a detailed step by step guide for this process.

This guide assumes that you are on a unlocked bootloader with TWRP recovery installed and want to revert to complete stock

This will erase all data on your phone. Hence first BACKUP!

14) type fastboot oem lock in minimal adb and fastboot and hit enter.

Before this came out I tried the reversal process incorrectly by typing fastboot oem lock as the 1st step (I know it says above you need a brain). Now it seems there is no OS to boot to. I can boot to TWRP and fastboot but my computer doesn't see the storage. Is there a way to push the the rom zip and stock recovery image to your phone via adb? If so what are the commands?

I believe you should be able to go into twrp, go to sideload mode. Then the command would be abd sideload filename.zip This should then push the rom to your phone and install it for you. It has been a while since I needed to do it, as now a days I mostly keep my phones stock and locked.

Thanks but that doesn't seem to work.

Link for Stock Recovery is down. Please help

Nice guide but isn't step 10 unnecessary, since the stock ROM will overwrite TWRP with the stock recovery anyway?

Thanks for the info. My phone's been acting very flaky since I rooted it, so I'm curious to see if returning to stock will make it a little less annoying.

definitely worth a shot

sometimes it doesnt and hence before we relock the bootloader its necessary to ensure we have the stock recovery hence the step.

Fair enough

unlock the bootloader
flash twrpagain
flash stock rom from twrp
flash stockrecovery image from twrp
reboot to bootloader
relock bootloader
reboot

My problem is, although I still have TWRP and fast boot, I don't have an os at the moment and need to get one via adb somehow.
I've tried adb push but can't find in TWRP. My computer doesn't see my phones storage either.
