This worked for me. Hope it helps if anyone else has questions. I was on the .320 leak, running rubiX 1.90 leak version. - Get the System only SBF from TBH. I think right now it's only in the TBH App... - After that finished I got stuck in a boot loop, went into stock recovery (Power + Home, release power, hit Search) and wiped data/cache - Booted up into stock .340. - rooted, bootstrapped, copied the rubiX 1.90 (leaked) over to the sd card. I edited the build prop because I want my version numbers to be "correct". - booted into recovery - installed rubiX 1.90 (leaked) / installed blackbar mod everything seems fine... market blew up and didn't restore my apps but that's what app brain is for.
