In this tutorial, we will show you the steps to revert to stock ROM from GSI. This article is valid for all Android devices and all GSI ROMs.
Thanks to the open-source nature of Android. there are a plethora of things to try out. For newcomers, they could theme their device, apply tons of icon packs, try out custom launchers, etc. On the other hand, the tech geeks take this a step further and tweak their device OS in the form of the root, or even try an altogether different OS based on Android. The latter is possible via custom ROMs like LineageOS, HavocOS, etc. For these to happen, you need an unlocked bootloader, which you already be aware of.
But there exist some devices that don’t have many developments concerning these custom developments. Exynos devices are always the first in line to suffer. This is because unlike Snapdragon and up to an extent MediaTek, Exynos chipsets are closed source. Therefore, there isn’t much in line for the developers to get hold of its source code and hence they can’t carry out developments for the devices equipped with this chipset. Earlier, we used to have only Samsung devices suffer this fate, but now Motorola too has joined this bandwagon. Many of its devices lined up for Android One series comes with Exynos chipset under the hood.
So for all these devices, there exists a life savior in the form of GSI ROMs. Generic System Images have been made possible thanks to the Project Treble introduced by Google alongside Android Oreo. The best part about this is that even if there is no official support for your device, you could still flash these GSI ROMs onto your device. The only major prerequisite is that your device should be Project Treble.
Well, its obvious that your device is Project treble compatible otherwise you wouldn’t have landed on this page to revert your device to Stock ROM from GSI. So with all that mentioned, here are the required steps to carry out the said task. but before that please refer to the Prerequisites section.

So to be on the safer side, it is always recommended to make a backup beforehand.
That’s it. Now follow the below steps to revert your device to Stock ROM from GSI
Instructions to Revert Back to Stock ROM from GSI
- First of all, boot your device to TWRP Recovery. To do so, use the hardware key combinations. The other method involves using the below ADB Command. But for that, you will have to enable Developer Options and then USB Debugging

adb reboot recovery
- Inside the TWRP, head over to Wipe and select Advanced Wipe. Then select Data, Cache, Dalvik, and System. Now perform a right swipe to wipe the selected partitions.
- Once that is done, head back to the TWRP Recovery. Now there are two approaches. If you have a Nandroid backup, then head over to the Restore option and select the latest backup. perform a right swipe to restore it.
- On the other hand, if you don’t have a Nandroid Backup head over to the Reboot screen and select Bootloader. This will boot your device to Fastboot Mode.
- Once it is booted to Fastboot/Bootloader mode, connect your device to PC via USB cable and follow the device-specific instructions to flash the stock firmware.
- For example, Xiaomi and Redmi devices could flash the stock firmware using Mi Flash Tool. On the other hand, OnePlus users could extract the stock firmware and double click on the flash_all.bat file. As per the Motorola users, we have detailed instructions, stock firmware files as well as the fastboot commands for all the Motorola devices.

- Connect your device to PC via USB Cable.
- Now boot your device to fastboot mode. Since the device is in bootloop, adb/fastboot commands will not function in this state. Therefore, you will have to use the hardware key combinations.
- Most of the devices follow the Volume Up plus Power key combinations. However, that works when your device is in a switched-off state. In bootloop, it’s very hard to turn off your device.
- So for that, keep pressing the Volume Up and Power Key, and as when the device reboots, you should feel a slight vibration. At that instance, leave the Power key but keep pressing the Volume Up key. This should take you the Fastboot/Bootloader mode even if your device is in a bootloop state, with no OS installed!
- Next up, enter the below command. Do note that executing this command will wipe your entire device, even the Internal Storage, well you have already been warned before.
- The entire process should only take a couple of seconds. Your device may reboot to fastboot. Even if it doesn’t, not an issue. Just make sure it is in fastboot mode after the above command has been executed.
