I am wanting some advice for my tablet (TF300t). I want to make an NV backup and duel boot this device with Ubuntu or Arch. I have already unlocked the bootloader and I was looking at backing up my NV Items. To add I have not installed any recovery I was looking at TWRP as it seems to be more stable on the Transformer than CWM. I am currently running10.6.1.8 firmware ( I bought it with this pre-installed) and androidroot.mobi says it requires 10.6.1.15.3 I have downloaded this version of the rom and unzipped put it on the flash and went to the settings and tried to update but its failed a few times and I have also downloaded it a couple of times. Also I was wondering about the boot loader and 3rd party roms. I have been reading but this device is a little harder for me to understand due to the complicated nature of what I want out of it.
Thanks for reading and any advice.
