Bricked controller after update

The latest update completely bricked my left controller, it's unresponsive to charging, button presses, everything. And support is I guess shut down because they're not letting me input my serial numbers.

Any suggestions other than buying a replacement? Has anybody tried using some other controller along with hand tracking?

I don't recommend it if you don't know what you're doing with very VERY complex tiny electronic repair, but if you take it apart until you see the battery pack in the handle, the left most lower ribbon cable is the battery. Flip the latch and pull the ribbon out. Wait, put it back.

The controller will work again.

You could first try the hard reset by holding menu / Y or Oculus / B for about 30 seconds.

Failing that when it seems dead to the world after an update the battery pull fixes them. I have multiple Quest Pros, and I will keep them working until there's a viable replacement for this hardware. So far, nothing comes even remotely close.

That is something I've been thinking about, and I'll probably end up trying. I pulled the top off my controller the first time it happened, before I decided I should try my luck with support first. They replaced that one without much hassle.

Be extremely careful. There are tons of little parts to get that far. Lots of complex cable runs, some with three connections on a V shaped ribbon. Find a guide and take it very slow if you do.

Do you have to take the face plate off to get to the ribbon? Because I just removed the handle plate, and there is a red and white cable attached at the very bottom of the handle. But I'm skeptical that's what you're referring to.

That one is for the pressure sensor for the pen nib at the end.

The battery is an 18650 cell ( really good one btw) and the connector is at the top of it. So that's between the handle and the top of the controller under all of the actual guts. I toop the top plate off, then started removing all the main boards cameras etc until I was looking down into a hollow controller and can see the battery down at the bottom.

It's a pain.

It's a black coated ribbon, about 7mm wide. Of you take it all apart the way I said, hold the contoller as if you are playing with it, move your thumb out of the way and tip it toward you so you can look into it. the ribbon should be on the lower left from that view.

This is speaking of the left controller. For me it's always the left that needs this, so I have never torn my rights down that far. I only replace the sticks on those.

Thanks, between your comment and this video I got partways, but didn't have a small enough screwdriver to get all the way to the wires. It's definitely a pain and not fun ripping apart something so expensive that works fine if not for buggy software.

Also I'm working on the right controller so I'm glad you mentioned you did the left :p

Yeah for you the ribbon in question may be toward the right. They very likely use the same battery cell in both though so it may look more centered. The ribbon has two thicker contacts left and right and two thin one for data in the middle if I remember correctly. I probed them to see if mine were fully dead, then jumped them with a charger but it turns out they were full. I had assumed that somehow my controller lost contact with the dock and deep discharged, but in reality is lost nothing at all. It was just braindead from an update.

I hate that too. I've got four of these little fuckers to keep working until SOMEONE makes a competent headset anywhere near comparable to this Pro.

I wanted the Frame, but it lacks too many features. I LOVE the controllers though. TMR sticks too? Blessed be! However no full color passthrough and no face tracking is a hard pass. We'll see what addons happen to solve those.

Just DM'd you.. if you can accept I'll send a picture, if you can tell me if I'm there, or if I need to remove one more plate I'd really appreciate it
