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):
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.

How to CM10 on Asus Transformer Prime
- 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.
- 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).
