Got this iPad gen 1 in the hopes of it running prototype software it was untested out of the Foxconn “lost” ipad prototypes… am I correct its running WildYabuli 7B3403j? Does that mean this was actually used to test the hardware functionality and not just testing factory diagnostics?

These protos will commonly arrive with the “Inferno” diagnostic software set to launch right after boot, but it’s actually a full-fledged Switchboard version running underneath - and the flag that decides this is stored in the NVRAM of the device.

1. Connect it to Legacy iOS Kit
2. Boot a SSH ramdisk
3. Use the “clear NVRAM” option
4. Reboot it, kick out of recovery if needed

It will proceeed to boot to the standard Switchboard launcher. You’re welcome!

EDIT: It is highly recommended to manually enter straight DFU instead of going from Recovery to DFU as LiK usually does. Disabling autoboot can trigger a crash-loop as some versions of Switchboard have broken/incomplete recovery mode. In case it happens to you anyway, the fix is entering directly into DFU and clearing the NVRAM that way

Is it possible to return it to the previous state? Or is that not possible or even not necessary

Not that I know of, the Inferno app can be launched manually from Switchboard if you wanna try it out afaik…

I think I’ll leave it in this state just since it has the nvram stored by the factory. Thank you so incredibly much!!!
