I recently flashed a stock system image to take an OTA update and have only booted to TWRP since. (I didn't flash it) I did root, though. When I was browsing /system I found that reboot-from-recovery.p was renamed to reboot-from-recovery.bak
My question is was this done by SuperSU or TWRP? and could this be the only modification?



It's done by TWRP.

If you're rooted, SuperSU modifies /system as well to put files there to give you root.

  • Is that the only change? Can I reverse it by, say, flashing "undo-perm-recovery-signed"? – Rhaegar Sep 17 '15 at 16:22
  • Yeah you could, but the reason TWRP renames that is so that when you want to boot to recovery, you'll boot to TWRP and not stock Android recovery. – DukeSilversJazz Sep 17 '15 at 16:32
  • Many Thanks. But it seems like a pointless thing to happen when TWRP is not even flashed. – Rhaegar Sep 17 '15 at 16:34
