How to revert to Stock Android

shbsssn

Hi,

Is this still the correct process?

The link states:

"The GrapheneOS factory images flash a non-stock Android Verified Boot key which needs to be erased to fully revert back to a stock device state. Before flashing the stock factory images, you should boot the device into fastboot mode and make sure the bootloader is unlocked. Then erase the custom Android Verified Boot key to untrust it:"

But there is no procedure described of how to do this. Clicking on the text " Remove non-stock key " does not do anything. It is not a link to anything.

shbsssn I have replied to your question in the other thread you posted in.

Please don't cross post.

You can use the CLI if you wish to but the recommended way for most users is the web installer.

The cli way works like a charm... Did it often without issues. Maybe a compromise for you. And it is not complicated.

Perfect. I had just found a thread that had what you wrote a few seconds before. And now I have got a double confirmation.

"fastboot erase avb_custom_key"

Is it literally avb_custom_key, or is this a placeholder for a specific key name?

e.g is it really something like.

fastboot erase Grapheneos-20210101-38282838473838-key

If you get my drift. Do you?
