I tired restoring to my custom IPSW got error 1600

I tried restoring to regular 2.0 and got error 1601

"It creates the ~/Library/iTunes/Device Support/ folder if not present, which should help with some 1600 errors people have been having."

I don't understand that.

Where do I find that folder?

right now my iPhone is stuck in DFU mode can't get it out of that.. tried ZiPhone iLiberty iBrickr etc.

Anyone have any solutions. Thanks?

Hello,

I read somewhere that you can get out of DFU mode by pressing for ~10 seconds the power and home button. Your phone will be back to normal operation.

Tell if it works

bye
