There is Zeki 4.1.1 release

For those in a hurry to get the 4.1.1 rom, it is out there. I don't and won't put it up yet since there are major flaws in the rom. It has turn off, sleep , and power issues. In almost every study I have done with it so far, you have to do a long hold OS kill to bring out of sleep. Also it has some wrong adjustments to the default cpu , that have to be moded at start with a apk file. Till these are worked out, I do not fill I can back the rom on this site!

the TBD753B comes with 4.1.1. however the rom is not complete compatible with the TB782B.
Be careful The Jelly Bean firmware has tons of bugs
especially not waking up after sleep / power off.
You need to hit reset button most of the time.
Its not rooted and can't be rooted through the ICS/JB Universal rooting
