ASUS Transformer Prime CyanogenMod 10 (CM10): One More Unofficial ROM Without Cherry Picks Appears!


The Jelly Bean party continues, and more and more custom ROMs continue to join and make the party livelier. Custom Jelly Bean ROMs have reached quite a stable stage when it comes to ASUS’ Transformer line of tablets, such as the mighty Transformer Prime as well as the ‘little less mighty’ Transformer Pad TF300T with only a few issues remaining, enabling them to be used as daily drivers. ASUS has already announced that both tablets will be receiving the official Jelly Bean update in the coming months but until that time, these custom ROMs can be used to get a taste of Android 4.1 quite early and quickly.

Some of the new features Jelly Bean brings to Android are a smooth and fast interface, advanced voice recognition (which beats Apple’s Siri in many cases), automatic useful information in the form of cards thanks to Google Now, a smarter stock keyboard, improved notifications with the ability to perform action right from the notifications menu, and a lot more, all of which CyanogenMod 10 (CM10) attempts to bring to a lot of devices, ranging from low to high-end, along with its fast performance and useful customization options.

XDA Senior Member craigacgomez has come out with his own personal unofficial CM10 ROM and released it for the community, which is built from the official CM10 sources and tailored to work with the Transformer Prime, though without extra features aka “cherry picks” found on other ROMs, providing a pure CyanogenMod experience. The ROM will be updated timely as CM10 development advances with the developer promising regular updates.

NOTE: This is an early build of the ROM, so there may be a few bugs and issues in the ROM, though most things should work properly. Also, since CM10 is in its early stages, the customization options may not be as many as they were on CM9 at this time.

The ROM has the following issues currently (quoted from the official development page):

Known issues:
1) Dock battery display is not working
2) Tablet remains awake when closed
3) GPS is not yet functional

Read on for the instructions on how to flash the unofficial CM10 ROM on your ASUS Transformer Prime TF201.


This guide is applicable only for the Asus Transformer Prime. Check your phone’s version in Settings – About Phone under “Pad EC version”. It has to be TF201 for this procedure to be compatible with your phone. If it’s not TF201, please do not try this.


Read everything carefully and thoroughly. The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

How to CM10 on Asus Transformer Prime


  1. This procedure will wipe all your apps, data and settings. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Make sure the bootloader on your tablet is unlocked. Go to the Asus Support Page → here, select Android in the OS drop down menu, then select Utilities, then download the Unlock Device App utility, install it on your tablet and use it to unlock the bootloader. This will void your warranty and also erase all data on the SD card, so make a backup (see point 1).
  3. Install ClockworkMod recovery using the guide → here.
  4. Download the latest version of the ROM from the official development page.
  5. Download the Google Apps package. This will install apps like Market/Play Store, Gmail, etc. which are not present in the ROM.
    Download Gapps  |  Filename:
  6. Copy the downloaded zip files from step 4 and step 5 to the internal SD card (do not extract them, copy the zip files directly).
  7. Shut down the tablet. Then boot into CWM recovery. To do that, press and hold Volume Down + Power, until a message a few lines of white text appear in the upper-left corner of the screen, then let go of the buttons. Then, in less than 5 seconds, press the Volume Up button to enter CWM recovery.
    In recovery, use the volume buttons to navigate/scroll and the power button to select.
  8. Perform a Nandroid Backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this ROM. To perform a backup, select Backup and Restore –> On the next screen, select Backup again. Go back to main recovery menu after backup is complete.
  9. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete.
  10. Then, select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file on the sdcard and select it. Confirm installation by selecting Yes – Install on the next screen. The ROM will start installing.
  11. After ROM installation completes, select choose zip from sdcard again, then select the file to install the Google apps package.
  12. After the installation is complete, go back to the main recovery menu and select reboot system now to reboot the phone and boot up into CM10. The first boot will take some time, up to 5 minutes.
  13. NOTE: To go back to your previous ROM, boot into recovery, select backup and restore then restore your previous ROM by selecting it from the list.
CM10 is now installed and running on your Transformer Prime. Visit the official development page for more info and to get the latest updates on the ROM. Share your thoughts on the ROM in the comments.
