I got my TFP yesterday and decided to put CM10 on it to see if it would fix the lag I was having (came with JB 4.1.1). Since it came with JB, I knew I couldn't use nvflash so I used the ASUS unlock tool which worked fine. I then downloaded TWRP 2.4.1 and flashed the JB blob file via fastboot.
Upon entering TWRP for the first time, everything seemed fine. I went in, did a backup (which I subsequently deleted by mistake) and wiped cache/dalvik/data/system and installed the official CM10 nightly. After flashing, I wiped cache/dalvik again and rebooted.
EDIT: So I flashed the Unofficial CM 10.1 here on XDA and it is now booting. So is the official CM 10 not for our devices with the JB BL?
