3GS NAND error, error 9 or botched software to IMEI unlock
Would appreciate any guidance if there is anything I can do with my old iPhone 3GS.
It was on 05.13.04 firmware, version 4.0.1. It got stuck there from a wrong pwanage/redsnow type upgrade.
So I bought a reputable IMEI unlock code and thought I was all set to upgrade to unlocked official IOSs. It sat in a drawer for a year and I recently tried to take it to 6.1.4 as per a non locked iPhone.
All seemed to go well but I'm now stuck at the plug into iTunes restore screen. Every time I try to finish the upgrade I get an error 9 (regardless of recovery or DFU mode).
I know there is nothing wrong with this machine as I've upgraded other newer non locked phones since. Anything I should look for in the traces that point to the dreaded NAND error as it it kernel panicking? The phone was working fine before the attempted upgrade…
redsn0w also can't put any old images back on.
