Quest Pro left controller not work/pairing - V71(controller update)
I didn't use my headset for a while but left it on the charging dock.
It looks like they auto -updated the system to the newest version .
( Auto- update check and sleep mode update are checked . )
V71 seems to have completely broken my left controller. It won't pair again , and it's not tracking at all .
Actually , the V71 controller update caused the issue .
They were paired and connected when the system update was completed . But after the controller update, the left controller started not working , and the controller icon turned into a "not connected " icon when the update was finished .Strangely, It was showing "Left controller is connected" via bubble messages.
To try to fix the issue, I tried to reboot my left controller , and it connected for 2 - 3 seconds, during which I saw the dot at menu that tracking was working for a very brief moment before the disconnected icon appeared on the UI panel again.
I decided do clean process steps from online guides .
1. Reset controller, ||| button with X => did not work.
2. 35 -second boot - up down - up process => did not work .
3. Factory reset the headset => did not work.
4. Perform a side-load reset => did not work.
It seems that a reset is not the issue, so I downloaded the Meta Horizon app to check stats and manage the pairing . When app run, They showed as connected , and both versions and batteries were displayed , proving that they are communicating.
To start from scratch, I removed the left controller from the app and tried to pair it again.
Now I receive this message:
"Your headset was disconnected . Please reconnect your headset to continue editing your headset settings . "
This message seems to pop up immediately when they find each other and attempt to pair .
With every attempt, they fail to connect .
The left controller seems to be fine ; the LED is blinking normally , it can access factory reset mode , and it can enter Bluetooth pairing mode . Someone mentioned that they must be on the same network and bandwidth , so I tried changing the Wi-Fi setting to 2.4 or 5 for my phone and headset , but that did not help at all.
So , in conclusion, I've done everything I could , and I don't believe my left controller has an issue or is defective because it was working perfectly a month ago , and I didn't drop it or anything.
I am assuming that this seems to be an OS or software issue.
Please tell me the fix or what more I can do. I really don't want to buy a new controller.
If I had dropped it or damaged it through hardware impact while playing , it would not be a big deal to get a new one, but this seems to be a software issue , not a hardware issue 😞
