What version of unrevoked did you use, and what is your hboot version? Depending one what version of unrevoked you used (if you kept an older one) and what file you used to unroot, that *could* be a legitimate error. Did you ever flash s-on, or just run a RUU (via PC36IMG.zip, I assume)? I'm going to guess you kept S-OFF if you're talking about flashing PC36IMG.zip for hboot. Just out of curiosity, why did you decide to unroot?
first i flashed the S-ON file then ran the PC36IMG.zip one thats big 202megs it wouldnt root so i ran the other PC36IMG.zip (3.33 megs) that fixes the boot loader my hboot is 2.10.0001 which its always been, ran unrevoke now im rooted
why i unroot? i wanted to start out clean since i was having problems, if that makes sence? lolnow gonna do this procedure xda-developers - View Single Post - [Recovery] [07-Jan-2011] RA-supersonic-v2.2.1
then this one
xda-developers - View Single Post - [ROM] - [01/15/2011] - MikFroYo v4.4 - ReEngineered Sense - Simply Faster.
anything else you can think of? steps wise?

after i have all flashed etc.etc, when i use disk drive to open up cells sdcard can i make a folder named ROMS then cut the rom thats on sdacrd and put it in that folder? then inside the ROMS folder make another folder named Kernals and do the same cut the kernal file and put it inside Kernal folder? just so everything is organized YEA i have OCD ROFL...
i like miks ROMS but once i load beta i know the finale will be out this weekend sometime, and i want to be able to change the clock to a clearer one so i can load some nice wallpapers, i just dont like that black of that clock covers wallpaper, plus i dont want to lose the SENCE of the phone either i like the animated clouds or whatever weather is at that time when you come out of sleep mode
