Canon 7D Factory Menu

[Donbass]

If you need to turn off the factory menu, I can do that without any third party software; just ask.

Please help to disable this factory menu. I bought my 7D used and cannot use it with a computer. EOS Utility does not recognize the camera. Where I live there is no Canon service and no one will help me

I was being careless today and called "SetTuningFlag" with no parameters. Managed to turn on factory menu and factory USB mode. PTP didn't work.

Tried a few things, didn't understand most of it.

Had to experiment in Qemu, and compared some ROM dumps. On my 1300D/T6 the flag is located at 0xfee60000+0x2c.
Default value is 0xFFFFFFFF, factory value is 0x0. Running `SetTuningFlag 0xFFFFFFFF`disabled the factory mode.
Or in Lua:
dryos.call("SetTuningFlag", 0xFFFFFFFF)
