If you have a different ASUS tablet, please look at this thread to see if there is a compatible version of this ROM.

I recommend you do a full wipe if coming from another ROM. Choose Wipe – Factory in TWRP. Do not do a full wipe from the bootloader.

You can restore data from Titanium Backups but please do not restore system data or apps from a previous version or another ROM if you want a nice clean smooth upgrade experience.

Don't forget to do a Nandroid Backup first and give the ROM 10 mins to stabilise!

ChangeLog from Asus:
1. Improve system stability
2. Update Polaris Office to v4.0.5030, to fix Spanish IME issue with keyboard dock
3. Support HDMI 1080P output when play Full HD video clip
4. Fixed the issue that sometime the Weather widget will fail to update weather data

Start by choosing the scenario below which reflects how your tablet is currently configured.

Scenario One

Factory Stock Android Operating System & Bootloader (Asus 10.6.1.x)


1. If you haven’t yet, unlock and root your TF700 by following these instructions.

2. Install the latest version of Team Win Recovery Project (TWRP) - TWRP XDA Thread

Download and install the Scott's TF700T Recovery Install Tool. Once downloaded, extract the files on your Windows PC, connect your tablet to the computer and run the Recovery Install Tool.bat file.

3. Skip Scenario Two and Jump to the Installing CROMi-X section.

Scenario Two

Custom recovery such as TWRP or Clockworkmod installed with a Custom ROM package


1. Update your bootloader to the latest one for your device by flashing from your existing custom recovery and then choose reboot from the menu.
Please don't flash these at the same time as a ROM package as the latter will cancel the bootloader/TWRP flash.

After the blue bar fills your device will reboot back into your normal ROM but you will be on the new bootloader and have TWRP installed

2. Next Step, please go to the Installing CROMi-X section.

Scenario Three

I'm upgrading from CROMi-X 4.x.


1. Congratulations. Jump directly to the Installing CROMi-X section.

If you followed the appropriate steps for your scenario above, you now have a compatible bootloader installed and a custom recovery such as TWRP.


1. Download the appropriate ROM package below and save to your internal or external SD Card. Do not unzip the file. Join the debate about which manner of packaging files is better (ODEX or DEODEX) or just use DEODEX since it allows for a bit more customization possibilities. ODEX may boot slightly faster but then again, it may only boot slightly faster the first time. Google ODEX vs DEODEX if you really want to understand.

About Fsync

Explanation by _that:

About the Experimental Features

During the install some features are listed as EXPERIMENTAL. I have left them as an option so you can play and enjoy debugging Please let me know if you used the experimental features like Extreme Tweaks, Cache2SD, Overvolting, Undervolting. if you want a stable smooth experience flash _that's kernel, with fsync disabled and one of the normal WW or US editions.

If you are a speed freak and don't mind the odd bug go for hunds with experimental tweaks, software rendering disabled and GPU OC, CPU OV and GPU UV.

Cache2SD is very experimental and may cause other issues so I'll leave that one up to you
