I am looking for a stock recovery for my phone (HTC One M7, rooted, s-on,CID: HTC__102, Software number: 4.19.401.11). But I cannot find it. The reason I want this recovery is that I want to experiment if it is possible to keep my phone rooted but going back to Stock recovery so that I can get OTA updates.
I have a nandroid back up of my stock ROM (I created it in TWRP, so it is after flashing the TWRP recovery), and also I have downloaded an OTA for my phone from forums.
Is it possible I can get an stock recovery image from OTA zip file or Nandroid backup?
