Install new update on rooted phone

[zech00]

Hi, I have a rooted T-Mobile M8 with the stock firmware, nothing modded other than it being rooted and having the custom recovery. I'm trying to flash the stock recovery onto my phone in order to be able to download the new update. So far so good. I have the original recovery on the phone, and when I download the update and try to install, it either stops mid way through the install and goes to the stock recovery screen, or it (only happened once, but I was out of the room when it did so im not sure what happened) rebooted and loaded the phone up, minus the new update. Now, I have for sure the stock recovery on the phone (red triangle), but it's still unable to install the new update. Any advice?

I just want the new update and then be able to reroot my phone and install the custom recovery again.

Thanks.

If you boot into stock recovery you can apply the update through there and it will give you an error message. Start there.

Why would I do it through there if it would give me an error message? I'm sorry, I don't follow you.

Because you need to figure out why it's not taking the update. If you don't know what is impeding the update, how are you going to fix it?

The update starts by doing two things. It checks that the ROM in the phone is the one it's updating (IOW, the stock ROM) and it checks that the phone has never been rooted. If either of these checks fail, updating the ROM could brick the phone, so the update "fails". (It actually just stops - "fail" means to not work as it should - it's working as it should, not risking bricking the phone.)

You have to flash the stock ROM, not the stock recovery. (Even unrooting usually won't let you update because there are usually signs that the phone was once rooted, and things could have been done while rooted that would cause an update to brick the phone.)

You actually DO to have stock recovery on the phone. Stock ROM should be common sense. When I update, I go into superSU and choose the option under Cleanup>>Reinstall >>Cleanup for reinstallation from Google Play. Do not reboot right away, take the update and reinstall superSU upon update completion. Your phone does not check to see if the phone has EVER been rooted. It check the system files to make sure nothing has been modified, it verifies that your getvar all info is a stock match and your ROM, KERNAL, RECOVERY are all stock.

Relock the bootloader and try again
