Hi, I have an untethered jailbroken iPod Touch 2G (2.2.1) and it has run fine for many weeks without any problems, but suddenly now I just turned off the ipod touch normally and then I couldn't turn it on again! It was not the battery (it was half battery left). It is untethered and I have rebooted my ipod touch 2g several times before. I tried to force boot it and many other things, but no results. DFU mode works but I really don't won't to restore it, I have solved many big problems without restoring, so it must have an other option. Now I can't backup anything and it will take hours to get back all cydia apps back, so please don't say restore... I tried to boot it with this: http://www.ifans.com/forums/showpost.php?p=1226988&postcount=33 and it goes to white screen then black then white again then it stays in white screen. I can then turn it off to black screen. So it's close to a fully boot. Don't really know what to then... Maybe a flash nor only ? Any commands ? (I have a mac) Can you guys help me boot it ? Thanks.
