Read on for instructions on how to to unlock your Atrix’s bootloader!

The process will involve the use of ADB, RSD Lite and an obvious unlock package. The instruction set may seem extensive but it’s not complicated at all. So let’s get on with it and unlock your Atrix’s bootloader, for a world of options awaits you!

The process to unlock the bootloader on Gingerbread is a fairly simple one, so you should skip to step 7 and continue from there. However, it is likely that most people would be running a Froyo based firmware, so we’ll start of the instructions based on that.

  1. Repeat: If you are on Gingerbread, skip to step 6. If you are on Froyo, continue with step 2.
  2. Turn the phone off and turn it back on by pressing the Power button, holding the Volume down button as the phone boots up.
  3. The phone will then read, Starting RSD protocol support.
  4. Run RSD Lite on your computer and press the button next to the box lableled Filename and choose the SBF file.
  5. Connect your phone to the PC and RSD Lite will recognize your device. Once it does, simply hit the Start button to begin the flashing process.
  6. The phone will reboot and will take quite a while so be patient as that happens. Once it boots up, power it off.
  7. Now open up command prompt and navigate to the folder where fastboot package was extracted.
  8. Hold the phone’s Power button and the Volume down button, letting go of them when you see Fastboot on the device.
  9. Once you see the message, Starting Fastboot Protocol support, plug your device into the PC and enter the following commands in command prompt:
    fastboot oem unlock
  10. You will now receive a unique device ID, continue to enter these commands replacing ### with the unique ID:
    fastboot oem unlock #### 
    fastboot reboot

Wait for the device to reboot and once it’s done, give yourself and the developer a round of applause! For updates and queries, visit the forum thread at XDA-Developers.

  1. Whenever I start flashing in step 4, my phone reads “sec_exception: febe, 35, 35”. RSD Lite then tells me that the flashing process FAILED, saying that phone did not re-enumerate after RAM-downloader was sent. What am I supposed to do?

  2. I want an expert to advise me and help me to do with this problem:
    In trying to unlock this file bootloader with rsd “zomgunlock-lite.sbf” giving 99% error Then disconnect and remove battery and the battery had 80% now I press the power button nothing happens no flicker, no logo I can not enter bootloader. not recognized by the rsd me. I’m very sad someone advise me not to do

  3. I’ve concluded that even though I’m running Gingerbread 2.3.4 from OTA update on my Atrix, the bootloader is NOT unlockable by Fastboot alone (that is, starting at step 6 above). I’ve got it rooted, but not with an unlocked bootloader. I’m going to have to go about it a different way.

  4. Not working for me..

    E:\downloads\atrixroot\fastboot>fastboot oem unlock TA2070K6IZ

    (bootloader) OEM unlock is not implemented
    OKAY [ 0.002s]
    finished. total time: 0.006s

    • follow the instructions from #1.  Install RSD Lite etc.  You are getting this error because your atrix is not unlocked.  You may have unlocked it using the code provided to you.  But phone is still unlocked.

      To verify what I am saying – are you receiving ‘unlocked’ text when you boot your atrix?

      Be careful when flashing RSD – nothing will work except fastboot.  before starting take some precautions:

      1.  download everything that is recommended by the article beforehand.
      2.  fully charge your mobile.

  5. I’m letting go of the volume and power buttons when ‘Fastboot’ appears, but I NEVER get to any message that says ‘Starting Fastboot Protocol support’. It’s stuck on ‘Fastboot’, and that’s it. Any advice?
