In this case you can simply skip step for flashing recovery and no script editing is needed. Some need individual parts flashing (system is flashed separately and recovery is flashed separately and boot or kernel separately, like in samsungs). It actually depends how stock rom is flashed (or rather what method it uses). Now similarly, we need to edit flash scripts so it doesnt go berserk on not finding recovery image. This is stock recovery, you delete this file. For ex if you open a stock rom archive in winrar, you will see some image file with name and extension similar to 'recovery.img'. In stock roms, the general procedure used is to put in a recovery image file. HOW TO PREVENT STOCK ROM FROM OVERWRITING RECOVERY: Here's more detail on how to deal with this in case of stock roms: Then open command prompt and enter these commands-> fastboot erase recoveryįastboot flash recovery PathToRecoveryFileAndItsName.imgįor ex if my recovery file lies in D:/Recovery folder, then I would use-> fastboot flash recovery D:/Recovery/TWRPblabla.img Next, connect phone to pc with usb debugging enabled.
