After you flash your recovery boot directly into fastboot(pwr&vol+&vol- all at the same time) then choose recovery. This is what I had to do in order to get CWM to work. If I let it reboot normally and then tried booting into recovery I would get the "Green robot" too.

Once you can get into cwm, when you select reboot now there will be a screen asking you if you want to disable flash or something or another. You want to click yes. This prevent the ROM from flashing stock recovery back onto the phone at boot(if you are booting into stock ROM). Hope this helps anyone here

Its a possibility. There's a greater chance that they will accept your warranty if you RSD back to stock before sending it in.

I'm having a problem with the initial flashing of these recoveries. I have downloaded CWM img and can open the Command Window, but so far, just putting in the program name and hitting enter is not recognized by windows-to flash CWM. I'm sure the answer is in front of me, but I can't see it. I am running Safesstrap. Thanks

Make sure you unzip the cwm.IMG file into the same folder as the unlock file. You also have to type: fastboot flash recovery then the filename

Thanks for the write up! Can't wait to see what kind of radio edits can be made for the 4g radio. in weak 4g areas, my wife's M is stuck on 3g whereas my HD has 4g consistently.

re-flash the recovery then unplug the usb cable before you shut it down then hold vol up and power and it should boot into the recovery u flashed

YOUR WARRENTY IS VOID. you take the responsiblity for your own actions. MAYBE one day there will be a way to relock or maybe spoof your device into displaying info from a locked version but, they will NOT fix your phone if you do this.

Incase anyone is wondering you can flash the Cyanogenmod Beta in Android Development Forum just find after you flash cwm. I love having Cyanogenmod without having to worry about the limits I had using Safestrap

Where did you get the cm10 rom from? the files that are linked are missing for me? also when you flashed cm10 did you mount only /system?

The only cm10 file on goo.im I can find from Hashcode on 11/14/2012, the version in the link is from 12/7, is that still available?

I can re-upload 12-05 to somewhere else, but Hashcode probably took down those files for a greater reason.

If you can find 12/07 it would be better. And I think hash tweeted yesterday that all builds for qcom going forward will be for unlocked devices only. So may be the reason all links are down.

WiFi on CM10 has always been finniky for me. As of lately the only way I can get WiFi to connect without eating my battery life is by turning WiFi off, rebooting, turning WiFi on, let it connect, then turn WiFi off then back on. If I don't do this each time I reboot my phone my phone usually drops below 50% within a couple hours.

    So if anybody's been reading the news, you may know that the bootloader for the Razr M has finally been unlocked!

    So here's a how-to on unlocking and flashing a custom recovery.
    A couple notes:
    This essentially makes the phone behave like an unlocked dev edition. You can flash any firmware, recovery, etc that you want. Be careful, don't flash stuff for other devices, etc etc...
    FOLLOW THE INSTRUCTIONS...
    Future OTAs may (will) disable this exploit. Do it while it can be done! Also, beware OTAs! They could disable this, or do bad things... Don't update unless you know it won't disable the bootloader exploit

    You need to be rooted, have the motorola drivers installed (link here - sorry, it's device manager, but they do have all the drivers in a nice package...)

    First, root if you haven't already...

    Next, download Motopocalypse.zip by Dan Rosenberg from here: http://vulnfactory.org/blog/2013/04/08/motorola-bootloader-unlocking/
    extract the zip and run
    Run through the entire process, until it tells you you have a bootloader unlock.
    Make sure that AP Fastboot indicates "Unlocked, status code 3"
    Also, when you reboot, you will get a warning screen about an unlocked bootloader.

    Next, choose your recovery. There are 2 options, TWRP (Touch Win Recovery Project) and CWM (ClockworkMod)
    either works, and each has benefits and downsides, choose whichever one you want.

    Follow the instructions for your flavor of recovery:
    CWM:
    Download the .img file here: http://goo.im/devs/Hashcode/scorpion_mini/cwm-recovery--scorpion_mini.img
    Move it to the same place you extracted the .zip above.
    Open a command prompt/terminal/command interpreter at that location (Windows short-cut: shift-right click, command window here)
    type the following (filename is the name of the file you downloaded, probably "cwm-recovery--scorpion_mini.img" unless you renamed it): fastboot flash recovery filename
    and press Enter. Let it flash, then reboot.
    The first time you use CWM, it will ask you if you want to disable something that would cause CWM to stop working. You do want to, so say "yes". Othewise, you'll have to reflash CWM every time you want to use it

    TWRP:
    Download the .img file here: http://d-h.st/QGe
    Move it to the same place you extracted the .zip above.
    Open a command prompt/terminal/command interpreter at that location (Windows short-cut: shift-right click, command window here)
    type the following (filename is the name of the file you downloaded, probably "twrp2.4-recovery-scorpion_mini.img" unless you renamed it):
    fastboot flash recovery filename
    and press Enter. Let it flash, then reboot.
    Now, you need to disable the automatic re-flashing of stock recovery.
    Reboot directly into recovery, and allow TWRP to disable the re-flashing.

    Now, you have TWRP running on your Razr M

    Please consider donating to Dan Rosenberg here for all the work he's done for our phones!
    Congrats! You now have a custom recovery on your Razr M
    Reboot into recovery, and you're done!

    ----IMPORTANT NOTE:----
    IF you are on the latest OTA and have NOT unlocked, it is impossible at this time to unlock. It may be possible in the future if someone finds another exploit, but not likely. Basically, if you updated without researching (that's why you shouldn't do that) or got a new one after the OTA, you're SOL for right npw

    could not agree more, if anything it wouldnt clog up the forums with redundant questions that end up making the proper information even more bogged down and harder to access. It also spreads information that is not correct sometimes, which is a major issue, Hopping in a thread and just thinking its your personal Q and A is moronically wrong , compared to looking at page 1 and the date of those posts, applying basic reading skills and deductive reasoning to possibly solving ones issue. You're going to have to learn for yourself anyways , so why not start asap. My non elitist two cents.

    IIRC, the guys behind Hydrogen Root were working on an bootloader exploit. A few devices became bricked and the project was abandoned.

    So by unlocking my bootloader it will make it so that I can flash CM10 in the stock ROM slot whereas before unlocking my bootloader TWRP would be unable to have permitted that?

    Not exactly. Before, we couldn't even flash TWRP, and everything required the stock kernel. Safestrap was an awesome use of an extremely hacky way of running a custom ROM.

    Now, we don't have any ROM slots at all... You just flash /system. So no ROM slots required...

    (Disclaimer: this is not meant to discount in any way safestrap or the work hash has done... We just have a better method now)
