[Asus Transformer TF700] berndblb:
ROMs for the TF700

KatKiss-KatshMallow by timduru (MM on the TF700 - who would have thought?) is still under intermittent but active development and it is a beauty. Multi-window support anyone?

CROMi-X is based on the latest Asus firmware (JB 4.2.1) for this tablet with many, many tweaks and improvements, but since there have been no further Asus updates, development on this rom has stopped. This rom would give you the most Asus-like experience on this tablet.

And here is the recent incarnation of this rom: CROMi-X Resurrected: http://xdaforums.com/transformer-tf700/development/cromi-x-5-4-resurrected-tweaks-t3273515

[MENTION=5313285]LetMeKnow[/MENTION] still releases a new teak here and there, so keep following the thread.

Development on all of the following roms has stopped. The devs have moved on to other devices

CROMBi-KK is based on CM11 and tweaked for this tablet but a little buggy. The later LP based roms from the same team are definitely better.

CyanogenMod is build from the ground up, CM10.x emulating JB 4.3, CM11 emulating KitKat (JB 4.4). CM was not build with a transformer (keyboard) in mind, but the dev has ironed out most of those bugs.

ZOMBi-X: From the same team that developed CROMi-X and CROMBi-KK. Based on OMNI rom with multi-window support.

ZOMBi-POP The (almost last) project from the CROMI/CROMBi/ZOMBi team. It's Omni based Lollipop for the TF700

A note: This rom will run with data formatted to ext4, which is the OEM default. But it benefits from /data on F2FS, the new file system developed by Samsung, more than any other rom before it. Changing the file system for /data to F2FS has become very easy since the TWRP team build support for it into their recovery. I wrote a guide for converting your data partition to F2FS here:

That same team took one final stab at a 6.0 rom for this tablet: http://xdaforums.com/showpost.php?p=65968239&postcount=3719

But I would call this definitely an unfinished product with a doubtful future.

CM12 I don't run CM roms - try it for yourself

There are quite a few more variants, check them out in the XDA Development forum and don't forget to make a nandroid before flashing anything new :D

Alternative methods to install TWRP

Edit February 2015

In this section I originally explained how to flash TWRP to your device using apps like GooManager (currently not supported anyway), TWRP Manager or Flashify from the Play Store which do it right from your tablet. These apps "save you the trouble" of getting ADB and fastboot set up and working on your PC. These methods still exist and they do work sometimes (and if you have root), but I will not recommend or promote them any longer.

Why?

Because I'v read too many stories about these apps failing, even flashing to the wrong partition - you name it.

If you are not willing to invest the time to learn the basics about ADB and fastboot (google "adb fastboot xda tutorial") and install the necessary drivers on your PC, you should not be flashing anything to your tablet!

GET ADB AND FASTBOOT WORKING!

I have spent quite a few hours helping users who got themselves into a situation where the only thing they could access on their tablet was recovery, but they did not know anything about adb/fastboot and did not set it up when the tablet was still working. To get it to work with a soft bricked tablet is much, much harder!!

Sooner or later you will do something stupid (I have done it and so will you) and ADB/fastboot may save your bacon IF you had it working when you didn't really need it.
