Quest 1 Headset Stuck in Setup Loop. Serial Number Not Recognized.

Hello everyone!

I've encountered a very strange and frustrating issue with my Meta Quest 1 headset and I'm hoping someone in the community has faced something similar and can help.

My headset is stuck in a setup loop after I performed a factory reset. The screen constantly shows a message to "Continue setup in the Meta Quest mobile app," and I can't proceed past it.

I have already tried all the standard solutions I could find:

• Factory Reset: I performed this both through the phone app and the Fastboot menu, but nothing changed.
• App Data Clearing: I cleared all the data for the Meta Quest app on my phone and tried to connect again.
• Manual Firmware Update: I successfully sideloaded both the latest and an older firmware version onto the headset. The headset updated, but the problem remains.
• ADB Commands: After the firmware update, I tried to run a command to complete the setup, but it failed because the headset was not detected by ADB.

Here's what puzzles me the most:

• Serial Number Not Recognized: When I enter my headset's serial number on the Meta website for verification, I get a message that the device could not be found. My account page also shows no registered devices.
• ADB Issue: Before the factory reset, my headset connected to my PC without issues and showed the "Allow USB debugging" window. Now, it doesn't.

It seems that the problem isn't with the headset or the firmware itself, but with its connection to Meta's databases. I have exhausted all the solutions I know.

Also, the headset hasn't been launched for a year

Has anyone else encountered a similar issue where the device's serial number is not recognized by the system? Are there any other options besides contacting official support?

Thanks for any help!
