22251 and INST_ERR12

[edwardhester]

See the same topic posted here but not sure anyone has a solution. Trying to upgrade from 22251 to stop the annoying auto-update request every time I start my car and the occasional freeze of the system requiring a soft reset. Master reset does not work, just hangs on continue. Any USB I try, I get the INST_ERR12 so that stops me from doing downgrades, reformat, interrogator, etc. Done numerous SR->SR-> to no avail. Anyone solve this yet?

All known methods are located here → APIM Sync Settings Not Saving, VER_ERR08 Errors, Cannot Perform Master Reset or Upgrades/Updates (Solved)

If none of those work, we do not have anything else to recommend at the moment.

Turn off the update warning to begin with.

The rwdata partition is full, known bug for 22251, so it likely does not matter or/and won’t make a difference…

I’ve turned off the updates in settings over and over and over. Next time I start the car, same messages.

That’s unfortunate. With the USB being non-functional due to the error code and inability to do a Master Reset, looks like I’m stuck?

If none of the described methods work, then yes…

Anything else you forgot to mention?

[edwardhester]

Like what?

Did you turn off wifi altogether in settings?

I have done that, it doesn’t stay and on the next key cycle, it gives me the same irritating messages. It seems to be very common with those on 22251 and using Apple Carplay.
