Unlock Motorola Photon 4G Bootloader [How To Guide]

photon-4G-unlock bootloaderPhoton 4G owners! We have confirmation that the bootloader for your device has been unlocked thanks to XDA-Developers forum member Yay 4 Juggs. This is huge news considering the Droid 3 and Bionic are to be released soon and this gives the devices a very good chance at a possible unlocked bootloader in the future. Even though the devices are different to each other, this just goes of to show that if it can be done on the Photon 4G, there’s a good chance it may happen for those two devices as well. As for now, it is the owners of the Photon 4G that are uber excited.

The unlocked bootloader has been packed into an SBF by the developer that is to be flashed on the phone via RSDLite. Nothing complicated, in fact the developer has made it even more simple for us. So here’s how to go about unlocking your Photon 4G’s bootloader.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.



The instruction set will be split into 2 parts, one for flashing the SBG via RSDLite and one for rooting the Photon 4G once unlocked.

SBF Flashing & Unlocking

  2. Download the SBF package and extract it.
  3. Power off the phone and then hold the Volume Up key and Power button together till you see RSD at the top of the screen.
  4. Now, launch RSD Lite on your PC and click the “” button next to the box labeled Filename.
  5. Choose the SBF file you extracted from the MR3 download.
  6. Plug the device to the PC via USB and RSD Lite should recognize the device.
  7. Hit the Start button and sit back and relax as the files are flashed to your phone.
  8. Once the SBF is flashed, the phone will reboot.
  9. Now download the Fastboot package from the link above and extract it.
  10. Run Command Prompt and navigate to the Fastboot folder, entering the following command:
    moto-fastboot oem unlock

  1. hiiii
    i was trying to install new rom from your site

    but now it has been stuck and shows” FAIL TO BOOT 2″
    Starting RSD Mode”
    what should i do now??


    THANKS IN advance

  2. Failing while using RSD Lite this is the error i get

    “Failed flashing process. Failed flashing process. Phone[0000}: The “Secure_Motorola_Flash” interface could not be found. The super-file is secure  and for re-flash; the phone needs a super-file that is not secure and not for re-flash (0x7066); phone connec”

    It just cuts off there.
    I have the Electrify which is just the photon on a different carrier. US Cellular.

  3. Step 7 of the unlock failed at roughly 50% and at this point, my phone will not reboot, nor can I get it back into RSD mode, or Android recovery. What now?

    • get your os file from the net(might take some time but this happened to my epic), find an odin prog that works(these thing are some times finiky(sp)).  while doing such if you can find the info on this phone look up the epic(both android…..), when you’ve done your research you’ll come across your os and one other important file needed to restore(hell, you may evenhave to use the epic file and images to complete this, but as long as you can get it to power on it should do an OTA update).  once you find everything, follow explained steps and ……bada bing bada boom!!!  phone will work once again.  PS(phone will need to be downloadmode)…
