I'm using a droid razr m xt907 by verizon. Yesterday an update was released for 4.4.2 kitkat, my phone is still rooted and i can't find the safest way to unroot it so i can get the update. Does anyone know the best way to unroot and make sure everything's normal again so that the 4.4 update will work this time? It stops at around 25% into the update. Thanks for any help.

Edit: I've tried a factory restore, i unrooted completely. My kernell is normal, my stock recovery is normal. The update just isn't working, and i don't know the best way to fix it. My bootloader is locked, so there was never any custom recovery or ROM's installed.

I'm having the same problem. I unrooted before the update but still not working. The update get's to about 25% of install then fails. I've tried about 4 or 5 times today. Factory rest and uninstalling root didn't help either

Exactly, i can't figure out what i'm supposed to do. Ive tried about that many times, and i've tried factory restoring, i've wiped the cache, etc.

Factory reset.
RSD to stock 4.1.2 in case some system app is missing.
Skip setup.
Try the update again.

Or just RSD to the new version.

Those would be my next steps.

Sent from my Nexus 7 using XDA Free mobile app

do you know any good tutorials for how to use rsd for this? cuz i want to just rsd to the new version if you can help me find the files to do that, i have rsd lite already.

It just won't work !

I also had a Razr M. i unroot it by SuperSU, but it won't update properly, same like others, 25%, then fail.

because you have not modified the xml file after decompressing the entire zip.



I have found the solution, you have to edit the XML file that is in the ROM. and delete the lines containing the words ("oem" and "var"). then you put the phone in fastboot mode and use the rom with the modified file will have only about 18 steps then when the last file billboards will ask you turn on the phone manually and status, restart your phone and enter mode fastboot again and finished well. NOTE: remember to put the usb debugging before starting everything. everything you do will be at your own risk, but so what I Realize, and it worked and I have my razr m with kitkat and before I could not for the same reason of the root. thank you all :) :D
