umm. well could it be that there wasnt enough room to make a backup on the sd card? now, when you are putting these backups in, are you unpacking them to the right place? or just trying to run them through the "install zip from sd card" function? because shinru's rom should work like that, if it was downloaded uncorrupted, but the backups have to be extracted and tossed into the right place in their respective folder like any other backup it makes
just double checking ya kno, but anyway, there is also a possibility you just had corrupted downloads, did you download them over a phone? are these ones you have tested on a different phone? also failing to make a backup wont corrupt a phone, and neither will a restore attempt that doesnt get past the initial checks, but i really dont know what could be the issue here if its not something of that nature. the version of cwm on the auto installer, the newest one anyway, is the same version that is posted on the cwm site and should be identical to the touch version which i use other than the fact that it doesnt have touch functionality, maybe it differs from the original release superr and i put out, but i dont see how, because that is the one and only thing that has changed other than the look of the tool it still runs all the exact same code as the fixed auto installer and the doomlord root method
