for details..

i have one ipod touch 32gb 4th gen which i have saved the SHSH on TU(TinyUmbrella)

the other one is my friends ipod which the difference is, its only 8 gig.

the problem is.. i think the firmware of the 8 gig ipod is corrupted and i can't trace nor saved its SHSH in TU the only thing i see on its TU is its ECID number.

so back to the question.. is it possible use saved SHSH blobs from one ipod touch to restore another ipod touch?
