So I'm in a similar boat. I have an old aria, and seeing a cm11, id like to try it (though a nexus is my dd). Anyway, i had cm7 on it, went through some old nandroids, and finally got back to 2.1 just after i used unrevoked on it. I've tried to flash the posted rom.zip (2.2.2, so i can then s-off and /or upgrade hboot [which i also tried to do via htcdev with no success]), it fails a sig check on my cwm 184.108.40.206, telling me bad, even though i verified the md5. Figured it could be the recovery, but i cannot flash the newer version on here via ./fastboot flash recovery recovery.img. i also tried ./fastboot boot recovery.img to no avail. I also couldnt flash the recovery through the old cwm. Im baffled a bit here... Any suggestions are welcomed.
Im thinking of trying to put my sim in it and see if the old att update would go through, any thoughts on that?
