To simplify this process for everyone I wrapped up all the the necessary tools, images, drivers, etc for getting your ME301T unlocked in a single rar file. This works as of 5-13-2013, I'll update it as needed when people report problems with any of the included stuff.
I cannot stress enough that I am not personally responsible for any of this work, I simply combined it for simplicity. Please follow the links below to thank the dev's that did all of the hard work for their time!
The rar file contains:
*Contains drivers for ME301T for Windows (From Asus)
hello,
the app to unlock the bootloader in tf300 works in me301.
I managed to install TWRP with the 4.2 bootloader and works fine. This allows playground to experimentation.
Roms and kernels works as well, but I only tried 3 of them.
Hope this helps
BTW I have been working hard on how to get all the 4 Asus sources into one update and have spent a week figuring it out. CROMi-X 4.6.5 is based off 10.6.1.15.3 (TF300T release) but uses components from 10.6.1.14.8 (TF700 release), 10.6.2.3 (TF300TG release) and 10.6.1.15.4 (ME301T release)
The appropriate config files, apks, libraries and modules get installed depending upon which device you have

o Changed Google Play Store to better 4.0.27 multi-dpi patched version by elesbb for TF201, TF300 and ME301 users
