Hey Everyone,

The Public Test Channel (PTC) for Quest v79 started to roll out today for Meta Quest 2, Meta Quest Pro, Meta Quest 3 and Meta Quest 3S.

If you're seeing an issue or bug after updating to PTC v79:

1) For issues: Go to our Get Help board and search for any existing thread on the issue, if you don't find one, make a new thread. Please add the tag "PTC v79" to the thread and in the title. This way everyone can look for just PTC v79 issues too.

2) For bugs: If you come across a bug, please post each one you spot in its own thread, to keep track of individual issues separately. Please make sure to also send in bug reports along with posting on the forums if you notice anything going wrong.

Share your impressions in the comments below and let us know if you see any issues.

We know it's tough when you run into a problem on a PTC build and want to thank you all again for testing out PTC and sharing your feedback! This feedback is extremely helpful to our engineering teams. We appreciate your interest and persistence in testing out the core functionality of software as we develop!

quantum0300 I would be happy to have a version that didn't require me to be in developer mode to connect to the link app on my PC.

Air Link had no problems before, now the pairing code appears only in headset (MQ2), but not in the pc app!
After a while the app says the code has expired, even though it never showed any code, so I cannot connect my VR to my PC which makes it useless.
Thanks for the update very much, please resolve this problem ASAP.

I'm thinking of leaving the public test channel due to the lack of in my view "expertise" in building and releasing of test software, I know its called public test channel, but their is supose to be varying degrees of a build, atleast to fall back on or to compair too, with some default devices and devices from the last build installed.  For the past couple of days I've been chasing my own tail trying to get past this constant connect and disconnect from the PC via a cable link and power draining out so fast and charging slow, thanks to xemmastormx1 we have a temp fix. But only after signing up to unessary things and getting verified . . . Normally I'd rant on and on but this battery was charged.

I had to change cables to get it not to rapidly connect/disconnect. I had mentioned before but ever since v74 or whatever version updated Android to the next version caused greater sensitivity for some users.  Some of us had to ensure we weren't using a USB3 Gen 2 port. 

In my case, the same cable in the same port I had been using for months suddenly stopped working. My rapid connect/disconnect stopped with a different cable, but still have to use the Dev mode to connect to my PC.

Also like you, I have noticed that it won't charge, and oddly seemed to lose charge when powered off but connected to the PC. In the past that would trickle charge it enough so it was full next time I went to turn it on.

I have managed to keep Dev mode on upon restart by resetting my headset and then enabling Dev mode during setup. Seems to be a permanent fix. Also there are rainbow artifacts still present with the v79 but the performance is about 1-2ms better over link. You'll have to open oculus debug tool and see how your latency is. Everything seems to be smoother. Only issue is my headset being overloaded after awhile with face tracking being enabled. If they could fix the performance leak on that then the quest pro would be like it was about 2 years ago when I bought it. I personally think v60 was the version that was most stable. Perhaps v79 is going in the right direction after all. They're honestly probably working on performance and compatibility due to the move to android 14. Hopefully they figure something out soon.

This update caused a boot loop that could only be solved by a factory reset - which showed that my left controller is now bricked. Best update ever, I truly feel as if my $1,500 has been valued as a customer.

Thank you for taking some happiness away from me.

Heute lief meine Quest 3 für ein paar Minuten, wie sie sollte. Dann musste ich sie für 2 bis 3 Minuten abnehmen und danach wurde der Navigator nicht mehr angezeigt.

Nach einem Neustart sah ich lediglich wie immer das Meta Startlogo, aber danach blieb der Bildschirm schwarz, wobei die Hintergrundbeleuchtung der Screens eingeschaltet waren. Auch ein längeres Warten führte zu keiner Veränderung.

Ich musste insgesamt 2 Mal ein Factory Reset durchführen, bis wieder alles funktionierte, wobei ich direkt den neuen Navigator bekam. Sehr ärgerlich, weil jetzt alle Apps wieder neu installiert werden müssen.

Thanks xemmastormx1  for giving us the solution to the cable link problem. I've emailed Meta support about ten times, and they haven't been able to provide this solution. They've only asked me stupid questions and performed stupid tests that didn't solve anything, even forcing me to buy a second cable. We should all denounce this ineptitude when it comes to solving problems that they themselves generate and not provide a solution like the one our friend xemmastormx1 , who is not affiliated with the company, gave us. The lack of professionalism of these people is intolerable. 😡

Hello from PTC version 71 to PTC version 77 I've been able to play bone lab modded with lemon loader just fine. But ever since v78 even the release channel version it's been crashing on that very colorful loading screen. I don't know why it keeps crashing maybe the allocated memory but whatever it is it is preventing me from being able to play bone lab with my friends.
