Currently the installed firmware version is: 6.0gm
and the baseband version is: 06.15.00-6.4_M3S2

itunes error recommended I revert to the the backup which I tried and now I have an itunes error : there is no SIM card in the installed in the ipone you are attempting to activate.

there is no SHSH backup

following instructions to downgrade form 6.15 to 5.15 with redsn)w o9,0.1b2 I selected the current iPhone2,1_6.0_10A403_Restore.ipsw from my Mac iTunes files but redsnOw does not support it.

I had downloaded a number of different 5.1 ipsw files to downgrade to with the intent of unlocking but can’t get that far.

Apsinthe did not support the attached device.

Is my io6 baseband different than the 6.15 Ipad file?

Am I using redsn0w correctly by targeting the currently installed 6.15 file?

Can I downgrade to 4.0 then up to the iPad 6.15 then down to an unlock able 5.1?

Is this phone now junk?

If you did, then try the 'Revert to lockdown' option within SAM options and then put the previously saved activation Lockdown folder back to /var/root/Library/Lockdown again and reboot.
