Quest 2 - unable to set developer mode (coincidentally Software update end of August???)

Yeah. I initially bought a Pico. Then 'up-cross' graded to Quest. Lovely headset, just kakk software/enviroment.

Suddenly about the end of august could no longer get into VR preview mode.

Now get errors when trying to reset developer mode on.

Oh lookee here. there was a SW -er-change (!) about the end of August.

Can't get an answer, says not supported in your region. (SA)

WORKED LAST MONTH.

Next hardware upgrade I'm going back to Pico. Im trying to develop innovative VR software not play frkn games or watch Videos or go around in not working what if i reset this circles, but thats all this thing can do right now....

        'Attempting to turn on adb in developer mode.'

        'An unexpected error has occurred. Please make sure that your headset is connected to Wi-Fi and updated to latest OS version.'

Duh all complied with. Repeatedly cycled. Though why insist on Wireless connection when I have a tip top USB connection seemes a bit retrograde to me. ANd same headset, same phone, same PC all see each other, and the various USB/WL/BT links...
