ok, so far I am still on DFU loop, can't turn the phone on or see any iTunes or Apple logo on it.
Today I tried to restore it on another mac, but keep having the same errors like 1600. Tried to restore using official firmware also, but then got error 28.
any ideas anybody?
OK now. I fixed the problem by draining out the battery, don't get error 28 anymore. Now can't restore to custom either official firmware. Getting errors 16xx or something like 31xx. Tried on mac and windows using iReb. Didn't fix the problem.
