Motorola Razr Gets Ice Cream Sandwich Firmware Leaked. Here’s How You Can Install it.


It’s raining Ice Cream Sandwich ROMs!! From everywhere, that is; and frankly, nobody’s really concerned abut whether it’s an official update, a leaked firmware, or a Custom ROM based on god-knows-what base !!! But the fact is, that Ice Cream Sandwich, or Android 4.0, the latest and greatest iteration of the Android OS, has taken the world by storm, in a way, that Gingerbread or Honeycomb, which were the previous iterations, ever could.

What we have here today, is a leaked Ice Cream Sandwich firmware, for one of the most popular handsets out there, the Motorola Razr ( GSM/UMTS Version). It comes to us, thanks to kholk, who is one of the Site Admins for the Eternity Project. Well, with all the leaks coming out these days, it’s a bit unsettling, but then, so long as they work, who’s complaining, right? What we are going to cover here is a quick guide on how to manually install this leaked Ice Cream Sandwich firmware on your Razr and then root it.


The methods and procedures mentioned to perform this process are considered risky; hence we advise you to only go ahead with it if you are confident of and know exactly what you are doing. We (or the developer) are not liable for any damage caused to you or your device, during the course of attempting this process. You have been forewarned!!!


This firmware is meant only and only for the Motorola  Droid Razr, GSM/UMTS version, model number XT910. This is not intended for and won’t work on Verizon or Roges Razrs. Attempting to try this on a device other than the XT910 may result in an unusable device. Please check your device model number in Settings–>About Phone

!!!Important Note!!!

Post updating to this firmware, there is currently no way of downgrading back to Gingerbread, till the SBU15 Fastboot ROM is leaked. So only update to this firmware, if you really can’t wait till the official OTA is out!!

How To Manually Update your Motorola Razr XT910 to Ice Cream Sandwich

  1. Download the ‘‘  file to your PC (Link provided above)
  2. Rename the file to ‘‘ (without the quotes, of course)
  3. Now connect your Razr to the PC via USB cable, and transfer the file to the root of external SD card
  4. Disconnect the phone from PC, and power it off.
  5. Reboot to Recovery mode.
  6. The phone should automatically detect the file and start the update process. If it asks you for confirmation, Select Yes.
  7. Wait for the firmware update to finish. Once it is done, reboot the phone.
  8. Let the phone boot up and display the initial ICS setup. Go through it, and sign in with your Google account.
  9. Go the Market, and download + install a Terminal Emulator app. This is a good one
  10. Launch the terminal on your phone and type in the following commands. This will restore your su backup file created by Voodoo OTA Rootkeeper, and thus restore root access
    mount -o remount,rw /dev/block/system /system
    rm /system/bin/su
    ln -s /system/su-backup /system/bin/su
  11. That’s it!!! Enjoy rooted Ice Cream Sandwich on your Razr!

TIP: Enable hardware acceleration from ‘Developer’s options‘ in settings.

    The phone is loaded with TI OMAP 4430 chipset with dual core 1.2 GHz Cortex A9 processor. So, you can expect a very powerful performance.

    i have updated my motorola razr xt910 to ICS and i got only i good thing and that was improved camera quality..all other were worse.. after updating i was not able to open any flash video, most of the applications ( were good running with my previous version) were closing themselves when i try to use. mobile started hanging. when i contact motorola they said they don’t know anything about ICS for razr XT910. Android is also silent, no one is showing genuine ICS For motorola razr XT910 released or not. news is about Leaked version only.(with a warning )….i downgraded again to GB…happy with it…
