Reverting to stock recovery in order to accept OTA updates ...
For anyone trying to apply any OTA updates, e.g., from Verizon, after modding your phone, restoring back to your previous version and wanting to go back to stock (for WHATEVER reason):
As you may have found out, trying to apply OTA updates with a custom recovery seemingly bricks your phone (it doesn't really, there are some nifty "dd" Linux commands you can use to get your phone to break out of the boot-loop it's stuck in).
Since I went back to my previously backed up stock ROM, I also wanted to revert to my stock recovery so that I could accept Verizon's OTA updates (if only because the popup reminders are annoying and a drain of the battery).
Here are the steps I followed, thanks to this thread:
- I downloaded the recovery.img from the link in Partager.info's post (#4) (choose the model subfolder which corresponds to your variant of the G2).
- I used "adb push" to copy the file from my computer to /sdcard (good to have on the sdcard partition as the rest get blown away when you flash a ROM)
- I installed "Flashify (for root users)" (found in the Play Store) on my phone
- I ran Flashify and chose the stock recovery file I downloaded which was in the /sdcard folder as expected (no need to put image files in specific folders; whatever works best for you)
- It flashed it in a blink of the eye and asked me to reboot; I did and it's worth mentioning I got the Android with the triangle (*clench*)
- I held the power button and forced it to shut down/reboot
- Upon reboot, I saw the Verizon boot animation (*unclench*)
- I checked for an update from Verizon and it prompted me to reboot and apply it; I clicked "Install now"
- It successfully rebooted and applied the update; what a relief to see the firmware update splash screen
Pfew. Thanks again, Partager.info and Steamer86.
