[Droid RAZR M General] megaghostgamer:
As many of us have took the recent Kitkat OTA we have a variety of questions. Since there have been many threads asking the same question or related to the same question, I will be making this thread to keep this from continuing.

Question: I have took the Kitkat update, is there any way I can root?

Answer: No, no known exploit works on the RAZR M, unless you have a unlocked bootloader. Then you can flash a custom recovery and flash a superuser.zip and gain root access (Credits - fredsky2)

Question: Can I unlock my bootloader now that I have the kitkat update?

Answer: No, the bootloader has been patched ever since the JB OTA. No exploits will work with the RAZR M.

Question: Will Rootkeeper keep root after the OTA?

Answer: I've yet to see it work so I assume no.

Question: When I take the OTA, will it lock my bootloader?

Answer: No, once the bootloader is unlocked, it cannot be relocked.

Question: Can I downgrade to Jellybean after the Kitkat OTA?

Answer: No, the bootloader is locked, meaning you cannot downgrade or even touch the kernel.

Question: How can I return my phone to stock so I can receive the OTA?

Answer: RSD back to stock.

Question: Where can I get the SBF Files for the DROID RAZR M?

Answer: Here: http://sbf.droid-developers.org/phone.php?device=8

Question: My phone won't let me take the Kitkat ota, what do I do?

Answer: Most likely it's because apps are disabled or root is present. RSD back to stock is typically the solution to the problem. If you want to RSD back to stock but don't want to lose your data, look for the question below.

Question: Can I sim unlock after I take the Kitkat update? (Suggestion Credits - gtmaster303)

Answer: Yes! There is a tutorial with video on how to do it found here: http://xdaforums.com/showthread.php?t=2487863 . MAKE SURE YOU HAVE PROPER DRIVERS INSTALLED!

Question: Can I flash a custom recovery after the Kitkat update?

Answer: No, unless your bootloader is unlocked.

Question: I'm getting a getvar error, how do I fix it?

Answer: In the xml file found in the zip, delete any getvar lines at the beginning of the file.

Question: Can I RSD without clearing data?

Answer: Yes! I asked myself and I'm adding this for others sake. Delete the <step operation="erase" partition="userdata" /> line in the XML file found in the zip. I suggest using it only for when you're on the same version of the update. So 9.30.1 to 9.30.1. Give credits to lem22 for helping me out! http://xdaforums.com/showthread.php?t=2755924

If there are any extra questions needed to be added, let me know and I'd be more then willing to add them!

If there is a user having problems that are listed in this thread, just link him here! :)

I posted both here and Q&A because questions seem to pop up in both places. I'm doing this to clean up the forums a bit better and keep questions from being asked multiple times. Hope this helps and have a great day! :)
