Ok, I’m losing my mind. I’ve got my blobs saved for the n-1 release and I can succesfully do a restore/update to the current apple version without issues. This is on a laptop (it bombs with error 1600 on mine). I can do this with either just the USB or USB+ Power.
However if I try and restore the n-1 version using the latest Seasonpass and iReb/Snowbreeze (with tinyumbrella TSS running) it fails with error 1600 on the firmware restore (near to last step). The device seems to be permanently in DFU after these attempts and iReb and Seasonpass see it in DFU mode and can seemingly dump their exploit).
I’ve tried restore/update to the latest versions and a clean run through on Seasonpass from the IPSW creation (it’s the right size) and I stil get error 1600. Doing restore/update to the latest and iReb and then Snowbreeze firmware (Correct size) also gives me error 1600.
All attempts are done with USB only, though I’ve tried with power and it makes no difference.
Tinyumbrella see it’s a DFU device (and then recovery device as it restores) and the TSS server is doing the trick.
I’ve tried checking that perhaps the restore was valid after each attempt but it doesn’t boot. The LED is blinking (not rapidly) and the remote seems to work (I can do the menu/arrow reboot) but nothing shows on the TV.
Has anyone got any ideas?
I’m going to try another PC, but I assume cable/PC are ok if I can restore/update to the latest version reliably.
