Alright, thanks bud. I've reflashed the original dump and it's now back to live onto 12611 that was patched and even loaded my FSD once it's booted.
I'll try the next the unpatched 12611 or the 9199 that I I used as a source to create the 12611.
EDIT: Ok, I tried with both original 7371 dump and freeboot 9199 dump but still just keep getting black screen. I selected the Aduio_clamp & DVD_tray from the smc drop down menu. Xell boots but no freeboot!!! no bad blocks present including the original NAND dump!!!!
