Hello,
I tried to use Asus official update tool (v1) to update BIOS on RTX3080 TUF OC.
Bios switch was set on perf. bios.
I followed the app instructions, but finally popped window the update is failed.
The card and spec was completely gone from GPU-Z.
After restart, PC boot'ed with black screen. So turned it off and switched to second Quiet bios. PC Booted normally.
I tried to use nvflash when boot on working bios then switch to bricked bios.
Nvflash won't flash default and updated perf. bios again, there is error PCI Block corrupted.
I also tried boot nvflash in DOS but it not recognizing RTX Nvidia card.

So it looks like the official update tool got fail with unknown reason and instead of flash newer bios just deleted / f**ked already existing bios.
Is anything I can do to fix it avoiding RMA?

Registered on this forum just now to say that the EXACT same thing happened to me today on my RTX 3080 TUF (non-OC). I just received and installed the card today. I went to the ASUS website to download the latest BIOS update dated 12/14/20 on their website, and ran the update before installing any drivers. BIOS update failed, just like in your case, and my computer wouldn't POST at all after a restart. At that time I had the toggle switch in the default Performance setting. Moved the switch to the Quiet setting, and the computer booted just fine. The BIOS update even completed successfully on this Quiet setting.

At this point, since this is a fresh new issue, I'll wait a few days to see if anything comes out to allow recovery by a user. I'm just relieved that I can at least use the card in one mode. I was so excited that I was able to fight off the bots and snag one on Newegg on Monday.

Hi, I updated a few hours ago without any problem. I have the OC version and proceed with the update in OC Mode. I didn't take any caution. The app requested to close GPUTweak, then start the Bios update with some blank screens and the asked me to reboot. I came here just to know if someone have the opportunity to test some new features. I hope you can fix it change it the switch to the non-oc mode.

xdk,

I can't post to your thread on the ASUS ROG forums yet since I just signed up, but I was able to flash the Performance BIOS back to an older version. I grabbed the latest version for my card from the link below, and made sure it didn't say "Quiet mode" at the bottom of the web page by the download button. I'm assuming that the .roms are probably specific to Quiet or Performance modes:


Then after booting up in Quiet mode, I toggled the switch on the video card into performance mode. I used nvflash 5.67 to flash the older .rom file onto the Performance bios with this sequence:

nvflash --protectoff
nvflash filename.rom

The first command I believe is needed to allow for writing to the EEPROM, otherwise you'll see a message that the EEPROM couldn't be written and the flash won't work. If the flashing works, you'll see a progress bar of the flash write process. You can verify the Performance BIOS version before and after with something like GPU-Z. Reboot your computer afterwards to verify that it works. Just make sure your toggle switch is set to the right side before you do any flashing. I'm not sure what the original Performance BIOS version was, but I'll stick with the latest from the TechPowerUp site until I see more official info from ASUS.

Im glad you fix'd your card, unfortunately I tried did exactly what you say, with all possible bios versions, and ev erything reasoned error: pci block corrupted :/

Sorry, completely forgot that you already tried that from your original post. I did a search for PCI Block Corrupted error and found one person with an older Nvidia card who experienced that message due to corrupt BIOS ROMs downloaded from TechPowerUp. They were able to get the ROM elsewhere and flash successfully.

Unless they used an Unverified Bios, it's PEBKAC.

Which bios is that? Do you have a Link so i can investigate and remove if needed?

Instead of using the Techpowerup database for BIOS since it doesn't have them all, you can extract the Asus update tool .exe to another folder with 7zip (like we do to manually clean Nvidia driver packages) and it will have all the BIOS's in there, along with an .ini file telling you which BIOS's update to what, so you can do it manually.

Use GPU-Z Advanced tab dropdown to look at Nvidia BIOS Message
94.02.42.00.AS26 is the newest Performance BIOS for my 3080 TUF OC

Hi. Have same issue with my brand new RTX 3080 TUF (non OC). Tried to apply Asus V2 BIOS using official tool but it failed just before 100% progress achieved. My Performance BIOS on TUF is now bricked . Have spent many hours to unbrick it with nvflash and official rom 94.02.42.00.AS28.rom or older one (AS15). Nvflash can see the latest rom version is somehow there and recognizes the card on low level, but GPU doesn't start (just a blank screen) in Performance mode. Still can use it in Quiet mode.

Reading the flash ends with 'PCI block corrupted '. Have tried all tricks described above but always failed with 'PCI block corrupted 1' just after flashing started.

Sounds like visiting Asus service (warranty) - hope it falls under FOC repair once bricked with official tool and official BIOS is somehow there.

Alternative to use external flash programming with a dedicated clips once the bricked chip is accessible somehow. In the meantime just Quiet mode - do not prefer to risk any more with second BIOS to have 100% bricked 3080.

EEPROM chip and the errors are identical for RTX 2080 story below :

I'm not sure what the original Performance BIOS version was, but I'll stick with the latest from the TechPowerUp site until I see more official info from ASUS.

I was curious a few weeks ago and tried the 12/14/20 ASUS BIOS update tool again, just to see what happened. I felt like I could take the risk since the recovery worked for me last time. The BIOS update actually completed successfully and now the Quiet and Performance BIOS' were both up to date and bootable and functional. I can't say for sure, but maybe there was an issue with whatever version the cards shipped with in this batch.

Latest BIOS has higher 8-pin Power limit(s) , but lower VRAM Power limit.

Anyone updated to latest BIOS and can get over 350W on TUF OC? Would be intresting to hear if the 375W limit can be reached with flashing.

So I need to flash the card's bios in both performance and quiet mode to update both? yes is the answer!
PerformanceBios.jpg


I just flashed my Tuf 3090 the the latest bios and also uploaded it to the tpu database. It needs verifying Wiz! 94.02.42.00.B1(Quiet mode)
and B2(Performance mode)

Alternative to use external flash programming with a dedicated clips once the bricked chip is accessible somehow. In the meantime just Quiet mode - do not prefer to risk any more with second BIOS to have 100% bricked 3080.

Finally managed to disassemble nvflash.exe with IDA so that 'PCI block corrupted 1' and 'Failed to Merge InfoRom' exceptions were disabled and suceeded to flash Perf EEPROM with the latest TUF Non OC VBIOS .

The problem once occured is really serious because official Asus VBIOS upgrade tool just bricks your EEPROM and no way to deal with this without nvflash modded . The tool looks quite similar for all Asus RTX 30s ".

ASUS VBIOS tool prepares temporary batch file (attached - added with extra .txt extension) and relies on nvflash behind the scenes just calling it with right ROM image (based on upgrade "database" stored within testini.txt) .

Attached nvflash logs for errors met and successful flashing log with modded nvflash.

Once you have Windows Professional on the board you can just enable Remote Desktop connection to your PC , next set the BIOS switch to bricked position and then disable your card in Device Manager. You can even reboot the machine and still control it over RDP (do not worry the display is blank). That's the way I did it and avoided RMA .

@Marmuc - Congrats buddy. I have the same card. I used the bios tool and managed to get it working, but at least we now have a solution for when it fails. Great work BTW :toast:

Have realized despite the card booted smoothly with no issues after my repair InfoROM and cert part were missing in VBIOS (mod was not ideal one but did it's main work). Fortunately had InfoROM backup (also could drop from second EEPROM) and flashed it next with original nvflash. Next to add cert part flashed once again full ROM with original nvflash once again. The VBIOS was 100% the same after all.

I'm sorry, I can't fix your problem, but I can say that I used the official NVIDIA BIOS flash tool with an official update, on my RTX 2080 (see specs) to fix a glitch that some cards were experiencing and it worked ok. My heart was in my mouth while it was running, though.

What I'm wondering, is that while you used the official BIOS flasher, what BIOS where you trying to flash to it and why. That would really help to troubleshoot your issue.

It looks like an RMA may be in order here in the end, though.
