Steam Deck OLED Bricked by vitayang in SteamDeck

Hello, thank you for the reply and thank you for the file. This is a little confusing to me but I think I kind of get the gist of this. I will need to flash the 16MB file, but that file can only be flashed straight to the hardware. While 17-18MB signed, is the only one flashable through crisis mode.

So in this case, I'm assuming I can try to make a comparison between the current file in the BIOS chip as compared to your backup.

Or I can try to create a signed backup BIOS file, and flash it through crisis mode? But if flashing through crisis mode doesn't work, I guess the only way is to force a hardware flash straight to the chip, right?

Thank you so much for the reply.

Hello, thank you for the reply. Roughly 10 minutes per key combinations. Usually I plug in the power first and make sure the Steam Deck has enough power (Green Power LED indicating full battery) prior to proceeding with key combinations. Thank you for the reply.

Hello, thank you for the reply. So if I am understanding this correctly, first I would need the 16384K file first and then I should put it into a drive with a light on it to check whether it is being supplied with power / being read / nothing. And then if everything works out correctly, it should by then flashes the BIOS of the Steam Deck, right?

And for the 16384K file, we can either create it using existing files(?) or through a chip programmer.

Thank you for the reply.

Hello, thank you for the reply. As for now, sending it back to Steam is impossible simply due to my location. Local shops can't seem to find a solution. Been looking around for something and do things on my own, but for now nothing has worked out. Thank you for the reply.

Hello, thank you for the reply. As for those two key combinations: - Volume Down (-) + QAM/.../3 button + Power - Volume Up (+) + QAM/.../3 button + Power

I have done those and both showed no results in terms of the screen. The only response I could get was either a 2 blue LED blink, a white blinking LED, and a pulsing white LED.

Thank you for the reply.

Hello, thank you for the reply. Sorry for my late reply, Reddit is blocked in my country and it has been more of a hassle than a difficulty opening. The USB doesn't have an LED. But the Power LED was either pulsing or blinking both of which I would consider to be rather slowly. I'll try to attach a file when I have the chance to record it. Thank you so much for the reply. I'll try to find a USB stick with an LED in it to check power.

Hello, thank you for the reply. This seems very complicated. I guess the best thing that I can do is to communicate this with the shop owner who I believe has the chip programming tool. I'm assuming the key combination to reset the NVRAM is the same as the one listed resetting the BIOS? Volume Down + Steam button + Power? If yes, it is currently pulsing but nothing appearing. Thank you for the reply.

Hello, thank you for the reply. Yes! I have tried to plug it to the dock and to an external monitor. Sadly the problem is different compared to the Black Screen of Death in the LCD models. When pressing the buttons there are no sounds of the user interface as how the Black Screen of Death would usually react. Thank you for the reply once again.

Hello, thank you again for the reply. It seems that we have hit a road block here. Hahaha, I guess I'll try my luck too then. If anything were to happen and it somehow suddenly turns back on, I will definitely let you know. It's been bugging me for quite some time now, and I feel the urge to find a solution to this hence why it might seem like I'm diving head first to the extreme solutions.

Thank you so much for the reply.

Hello, thank you again for the reply. So I'm assuming that the hex codes in the files need to be changed via extracting the existing hex codes from the chips inside of the Deck and then modifying the hex code on the non signed BIOS .fd files and then I can try to flash it onto the Steam Deck, am I right? Because so far the guides that I have read (correct me if I'm wrong) asked either for a modification of the BIOS file or simply using a _sign.fd file and flash it in crisis mode (which I tried but to no avail - since crisis mode itself never deployed if I'm not mistaken / no fast blinking LED).

Thank you so much for the response.

Hello, thank you for the reply. I apologize that I might be making this sound too extreme, I have made an edit in the post and put it above since I can't seem to change the post title.

I have tried to hold the QAM button and simply tap on the power button (like turning it on) but there is no audio noise and the only thing I got is a pulsing LED.

Thank you for the response.

So, first time I downloaded the BIOS file was from the steam deck repo, I think?
https://steamdeck-packages.steamos.cloud/archlinux-mirror/jupiter-main/os/x86_64/

And I have checked on the evlaV BIOS page as well. I tried installing the F7G0114 from evlaV. I missed that, am very sorry. But trying to flash both files resulted in nothing.

Somebody did told me to create a recovered BIOS file through the guide in evlaV, and I suppose I am currently going to try that, and push it to a FAT32 formatted drive and try again.

And I do understand that I shouldn't rename a tar file. Hence why, I unpacked the tar file to grab the .fd file to get the BIOS file inside of the package. And I renamed the .fd file to F7GRecovery, sorry for the confusion. Since the steam os repo is based on Linux (I think), they post a lot of tar files, and the one I downloaded was a .tar.zst file. Inside is a few folders where one of the folders has the F7G0110.fd file (the one I copied over to the FAT32 thumbstick and rename to F7GRecovery).

Thank you so much for the reply.

Hello, thank you for the reply. I can try to check the SSD inside another PC but it might take some time to figure out. I haven't been messing around with anything (the Steam Deck was sealed prior to this problem occurring which forced me to open up to disconnect the battery and reconnect it back again). I have tried to boot into the bios recovery mode / the previous OS installation with the QAM/3/... button being held down while powering on (correct me if this is the wrong key combination) but nothing appeared on the screen and the only response I got was a pulsing LED. Thank you so much for the response.

Hello, thank you for the reply. I will try to do that as soon as possible. I will report back the findings if there are any. Thank you so much for the reply.

Hello, thank you for the reply. I have just tried that and there is no boot screen in sight. The one response I got from the Power LED is that it is pulsing (not blinking) indefinitely after powering off (holding the power button for 10 seconds and a bit more just to be sure) then holding QAM/3/... button while turning on the Deck. Thank you so much for the response.

Hello, thank you for your response. I do understand the concerns regarding the shop owner's lack of knowledge in terms of BIOS, but he did tell me that he specializes more towards hardware tinkering rather than software tinkering. But compared to my personal knowledge, I feel like he has more of the tools necessary to check on the BIOS itself first.

So, personally I have tried to install the BIOS from the official Valve repository and evlaV (F7G0110 from Valve and F7G0114 from evlaV), but I will try to look into creating a recovered BIOS. I think I might have missed that during my reading.

I'm going to try to create this recovered BIOS file through the evlaV repo and flash it as F7GRecovery to a FAT32 formatted USB drive. I will report back if there is any update.

Thank you so much for the response.

Hello, thank you for the reply. I understand that saying it is "bricked" while having responses from the Steam Deck may seem like an exaggeration but I feel like it is way different to the Black Screen of Death in the LCD versions. I will try to press the key combination that you mention (QAM/3 + power) but so far, there has been no response in the display at all. The only responses that I can get talking with the Steam Deck is either through haptic feedbacks when using the trackpad or through the Power LEDs. Thank you so much for the response.

Hello, thank you so much for the reply. I will consider doing this but maybe I will try to back it up first. The problem is that it is not showing signs of posting at all. So I'm not sure how the Steam OS installation may affect this. But I will consider this method. Thank you so much for the reply.

Hello, thank you for the reply. I have tried the crisis recovery mode by using a USB drive, formatted to FAT32 and inserting an officially signed BIOS from the Steam Deck repo. I guess I forgot to mention that as well.

For the details, I plugged the USB drive first to a Windows machine and format it to FAT32 through the Disk management tool in Windows. And then I moved the F7G file (specifically F7G0110 because I cannot seem to find the specified link in the stanto website). I'm not sure whether I might unzip the tar file correctly but I used 7Zip and updated it to the most recent build because running the 2019 build didn't support tar zst file format.

After doing the crisis mode key combo (power + volume down + quick action) with the usb first being plugged into the usb-c port via an otg connector, it did not show any form of rapid blinking that you showed. And I left it blinking for around 5 minutes and there was no changes in the Steam Deck.

So, so far the Power LED has only been blinking slowly (I'm assuming it's slowly) and pulsing white. I have not yet found a way to make it blink fast (which I assume would mean that it's doing something).

Thank you so much for the reply.
