By accident, bricked my Polaris GPU

[shadowvault]

I'll just copy from another forum, thought if I downloaded everything that I needed from here, speaks by itself.

I've flashed my RX 550 vBIOS about two days ago and it went sideways, tried some "blacksmith" such as DOS reflash and everything except Linux. What happend was that I had a mining RX550 as a daily use since I don't game anymore or if, maybe a "This war of Mine" small light games when I remind there's even such things and speakin of reasons for a logical one, there's none for me in last years. Anyway, my GPU was the 640SP versions ( shaders cores) and the vBIOS in question was from the "OC" variant which is a official supplier by maufactuer itself, but it had 512SP. I did the flash from Windows using ATIFlash not Winflash, ATIFlash I know even program itself has stability red flags, and after say 2m my computer froze including my peripherals and I restarted the desktop from button. I woke up with a unreconizable GPU + driver unistalled ( 21.5.2) and that was it. Even in DOS it says "Adapter not found" error 0fl01. GPU does works so unlike what you knew as a wrong flash and GPU not displaying image or such in my case it does, but I can't install the official stock bios back.

BIOS codes from stickers > B0260 on back and front E367. Is possible to bring it back to life or do I throw it into abyss. Also I did plug it a while back and me thinks is last time, since I don't think there's a two-way highway and I've got somehow to "ROM UNLOCKED" ( from within Windows) with my original 640SP BIOS, downloaded from here. I didn't do any backup beforehand of the "stock" one to call it so, I dunno what might differ since is same GPU but still "Adapter not found" big error label thrown by amdvbflash utility ( tried 2.93/3.11 latest). Tried DOS, same vectors, one thing I didn't try because I think is just a waste of energy is to make a partition for a random Linux install and do same thing I did earlier. I don't think is just as easy as download Linux > install > open terminal prompt > *insert*. I dunno

How to recover from a bad video BIOS flash

Almost every day there are new threads regarding bricked graphics cards due to wrong BIOS flashing, and since eidairaman1 is no longer around to help, here is a guide how to deal with a bad VGA BIOS flash. Find the correct BIOS First off, you'll have to find a copy of the original BIOS. In case...

Hello @shadowvault
Yes i am from Romania, but since it is an english speaking forum let's maintain it this way.
Well, as long as i don't invite anyone to join this forum, pointing in my direction was a bad move.
On the other hand i am a lawyer also so i am aware of legal implication more than you can dream of.
Let's go back to your problem.
The only thing i did was to offer you a free guide on how to recover from a bad BIOS flash.
Yes the amdvbflash that i use works with -f argument so don't insist on that.
On all my post you will find my advice that a user must use the 2.93 version for Polaris cards.
Since you made a mistake don't throw with mud on the people who try to help you.
I would advice you to read all my posts where you will see only my good intention to help others.
I am not payed for this.
I'm out.
Cya

Right thank you for taking your time to answer, lemme put this way. If I cannot make the utility detect any adapter, returns adapter not found. What can I do? what blindness do I make it look so? i just said what issue I have and you seem to not get it and somehow project errors from within yourself onto others, which = greed. DO I download dos 4.68 from within 2.93 section just 2 "ledders" above what exactly do I do? because if I am to download 2.93 I did it previously returns "Cannot find discrete ATI card". You might stop wanna over react and actually read what issue I got going on, as for reading my way of bricking GPU is very different than people who needed to short BIOS chip to get to post, I last time I say. GPU WORKS, WORKS BUT CANNOT HAVE ANY NOT EVEN STOCK BIOS PUT BACK. As simply as night.

Pretty frustrating, I know.

Looks like you've tried everything just about. I think it's likely best just to cut your losses and buy a modern card. This one is very old and even a lowish end modern one will outperform it and have better features.

@eidairaman1 if you can help at all.

 

[shadowvault]

So windows does detect but check this out. I managed to boot with iGPU enabled in BIOS but now on GPU instead of iGPU, it did not give me display first time second restart did

Pretty frustrating, I know.

regardless of situation that's inevitable, but just as a to see if is possible to get it back to life

Hmm

eidairaman1 is on hiatus from TPU, he will not be responding, unfortunately.

@shadowvault If a DOS reflash doesn't work, the next step is usually a CH134a reprogrammer or replace the card.

That doesn't sound like my cup of tea, I've tried is dead, trapped in a theater piece. This is what all participants of this thread, should've answered wait, not all just 1 you know "Take one for team"

I know how frustrating is to work with a card that worked 2 hours ago.
Trust me i have been there.
When i suggested to use the 2.93 version i knew exactly what i am telling.
The procedure you must follow is simple:
boot in safe mode using iGPU as the primary card.
use the amdvbflash -i to check if the system identify your RX550 card.
If not than there is a small chance that you can unbrick it by using the clipper trick.
If after the clipper procedure it is not recognized by the system then you must use a last resort the CH programmer.

But that does not justify your behavior.
We are here to help.
If you do not like our way you are free to ignore us but do not speak like you did before. Are we clear ?

 

[Count von Schwalbe]

The guide Imperio linked has a possible workaround - short pins 1-8 on the BIOS chip and try to flash from DOS.

@Count von Schwalbe

I'll temporary use my old museum HD 4870, since RX heatsink screws dont go inside because even these have.. Size? I am tired this whole gpu thing.. I used some Bison Adesive for 2 holes since I have other 2 from GPU what I think protector some but that I can put back easily, what I cant is GPU heatsink so I'll see that later now only if holds

Finger crossed.

Good morning fellow community and hopefully y'all have a great week because I know I will. My 256bit GPU will work tonight, me thinks to leave it until Sunday which I'll probably do, that adhesive isn't the "instant bond" version but his cousin 2-component polyurethane. What can I say, first of all this GPU i got it at launch, I dunno how it doesn't make rounds around here ahaha, but doesn't have original cooler anymore because I gave it to someone and that someone did some shady things, in layman terms. Has a disciplinated owner though, what knifes more than this and is from ASUS, 1 GB GDRR5, yeah. I just went to eMAG to my shop to make a shop reservation which I'll go probably this noon, they said they'll deliver it today, is a cable after all.

I re-flashed a GPU bios from within the Windows has like a image recovery option once. The GPU wasn't stable enough to boot into windows, but it would post and could load into windows image recovery slowly prior to windows. Most people wouldn't even think to try it I don't believe and it beats trying to flash blind. If it doesn't even post to bios that's probably a bad sign that it's actually bricked beyond repair potentially. I honestly don't know since I've never had a bios flash where that happened.

 

[shadowvault]

All these sails ahead, I got my HD4870 to spin boot one time just to go into BIOS change to PCI express and been stuck in a nonsignal restart loop, maybe my 520w sii12 some from seasonic 80 plus bronze isnt enough although it should. Peripherals froze, then now on iGPU goy my mouse detected back so form of random electricity waves, has a Energizer cmos though so that shouldnt be an issue and yeah lets shake hands here fellow community. Have a easy week

If anyone knows I'll say to avoid because I guess within psu shore system it got somehow affected. 4870 is a hungry cat and I can guess try another random psu 600w ^ but why would I?

 

[InVasMani]

Perhaps undervolt/underclock the CPU if you can ever post into the bios again if it's a under powered PSU problem potentially that is. It's a good sign though that it at least showed a post code.

Good evening, I was reading should I mistaken myself and this card needs an adapter? DVI-VGA. Is I think, the HD 4870 512MB version rev 1.0 something, I do think it needs an adapter, I do have UEFI though not Legacy Bios so, but until there there needs to be this adapter checkbox verified. I dunno, years since I used this GPU has so much history, would be this easy to get my VGA no signal black? No bro, I actually not posted code, installed drivers! yes but no display

DVI-To-VGA Adapter

This definition explains the meaning of DVI-To-VGA Adapter and why it matters.

www.techopedia.com

i was reading this and it rains wilds with compeling methods made by manufactuers but anyway, we buy them bc reasons

 

[InVasMani]

If the GPU itself doesn't post boot up code/image assigned as the primary output to the display upon boot up I'd presume it is a dead GPU, but standard trouble shooting double check all involved power and display output cables to ensure that they're properly plugged and secured.

@Count von Schwalbe

I say boys boys, but I need help. Good evening, techpowerup community! I do belive I have a working card but since I have a UEFI motheboard it doesn't work, is there anyway to somehow pass this verification? Little time since this thread, honestly no useful answer

 

[Count von Schwalbe]

Enable CSM on the motherboard should work

 

[shadowvault]

Enable CSM on the motherboard should work

is..
yes

it did detect in atiflash 2.93

 

[Count von Schwalbe]

Please clarify the issue. Is the GPU you describe as not working displaying image?

 

[shadowvault]

It needs something else, what can I do, at least help me save my HD 4870 for sake of it

While flashing it randomly restarted

It was at someone else for a while, seems he had hood problems.. almost 1 trilion wow, almost. I would put it 1trilion.

 

[Count von Schwalbe]

Ah yes, generic error.

So to get this straight, you were flashing the HD 4870 and it restarted. Now you have the error can mean anything. I would usually encourage the "Paperclip Trick" next, where you short BIOS pins 1-5 until flashing is complete.

 

[shadowvault]

Ah yes, yo boy you read what it said. I'll get from a friend i spoke a GTX 560 temporarily
