I forgot the pass code, and heard that I'm going to need to restore it. The firmware is at 4.1, and I don't want to upgrade to 4.3, so when I tried update by holding the SHIFT key and clicking on 4.1 firmware file, it gives me errors. I tried tinyumbrella to save SHSH files, but my itouch doesn't have any saved. Basically, does this mean that I will have to restore it upgraded to 4.3 firmware?
