MEG X570 Godlike clear CMOS after BIOS fail

Hello all, and hope you're well!

I gravely need your insight on this:
yesterday I tried to update to the latest BIOS version ( 7C34v1A, Release date: 2020-09-07) through the MSi DragonCenter app on my desktop.
The update resulted in a failure (fml) with a recurring black screen, and Windows never booting up. I can't even get to the BIOS screen to try to resolve the issue from there.
The "ClearCMOS" button on the I/O panel lit up, and I tried pressing it when the PC was shut down, but no luck there either. Searching online and going through the mobo manual, I inferred that I needed to shut down and unplug the PC from power, and then completely remove the CMOS battery from the mobo and short the JBAT1 header pins with a jumper cap. I also went through hell to try and find where the hell MSi decided to place the CMOS batter on this one.
Where I need your valued insight, is this:
1. The CMOS battery cannot be simply removed with my fingers, as it is wrapped with insulated tape and glued on a surface. It has these two small diode cables, which I unplugged from the mobo (the only thing I could do for now). I left it like that overnight and I'll attempt to see what happens now, but in case that the battery doed indeed need to be replaced, how do I do that?
2. The mobo came with no jumper caps (ridiculous for a product of this price) and I'm having a hard time trying to find any. If I try to short the pins with any other conductive surface, e.g. a screwdriver, will it work as well?
3. In case the problem persists even after the above steps, what can I do from there? I believe that MSi warranty covers the above issue, seeing that the BIOS fail occurred through their app, and their BIOS version, right? I purchased the mobo not 2 months ago, and have registered it in their website.


I need my PC back asap for my work. I filed a ticket through their website, but no reply from their end so far.

Thank you all for your time and input! :)

Well, there's your first problem. I would always flash the BIOS from the BIOS itself, using the M-Flash menu entry. The Windows apps are unreliable, this guy apparently bricked his mainboard that way: https://forum-en.msi.com/index.php?...-motherboard-bios-update.345519/#post-1998994

Yes.

and then completely remove the CMOS battery from the mobo
No, never. Shorting the Clear CMOS pins with a screwdriver, or in your case, pressing the Clear CMOS button for a certain amount of time with the PC turned off will fully suffice.

and short the JBAT1 header pins with a jumper cap.
No, in your case. Since you have a Clear CMOS button on the back. You just have to keep that pressed for the amount of time mentioned in the manual. 10 seconds should do. A short button-pressing will not do.

1. The CMOS battery cannot be simply removed with my fingers, as it is wrapped with insulated tape and glued on a surface.
The battery is not meant to be removed. The Clear CMOS button will short the battery's power supply, which is far more convenient.

2. The mobo came with no jumper caps (ridiculous for a product of this price) and I'm having a hard time trying to find any. If I try to short the pins with any other conductive surface, e.g. a screwdriver, will it work as well?
You never have to short the battery pins directly. Either there's "Clear CMOS" pins on the mainboard (seperate from the battery), or there's a Clear CMOS button on high-end boards. Taking the battery out is a quick-and-dirty way on boards where you don't have the manual and can't locate the Clear CMOS pins on the board. But mostly for older or more low-end boards, not high-end boards with a seperate button for it.

3. In case the problem persists even after the above steps, what can I do from there? I believe that MSi warranty covers the above issue, seeing that the BIOS fail occurred through their app, and their BIOS version, right? I purchased the mobo not 2 months ago, and have registered it in their website.
Just like the guy from the above thread, you can explain the whole thing, saying you just used their app in Windows and did nothing wrong on your end. Then you should either get the money back or get the board replaced (if there really is no way to resurrect it).

Thank you so much for your reply! In the manual that came with my motherboard it explicitly says in the Clear CMOS section that I could use a a jumper cap to short the JBAT1 pins, for about 5-10 seconds.
Before disassembling my PC, and after I shut it down and disconnected it from power, I did keep the clear CMOS button pressed for a prolonged time (can't remember exactly how much, but close to 10 seconds definitely). I should say that after my PC was shut down, the clear CMOS button was lit red, but turned completely off after I unplugged the PC from power.
After it turned back on, it came to the black screen with the message "press F1 to enter setup" to recover BIOS settings. It did recognize my mouse and keyboard, but nothing happened as I pressed F1. That's why I'm reverting to the more extreme solution I'm following now.

Something else: my motherboard also came with a BIOS switch, which according to the instructions can be turned to the backup BIOS to try and recover the main BIOS through there. I switched my PC off, turned the switch to the other BIOS, turned it back on, but I was met again with the "press F1" screen mentioned above. This is why I'm trying to somehow "reset" the CMOS battery.


Do you believe that if I assemble my PC back on, turn the switch to the main BIOS, and keep the clear CMOS button pressed long enough, my BIOS will reset to the factory values? Nowhere in my manual does it mention a specific amount of time that the clear CMOS button should be pressed though.

From your manual, page 25 of the English manual, https://www.msi.com/Motherboard/support/MEG-X570-GODLIKE#down-manual

Clear CMOS button - Power off your computer. Press and hold the Clear CMOS button for about 5-10 seconds to reset BIOS to default values.
Flash BIOS button/port - Please refer to page 67 for Updating BIOS with Flash BIOS button.
You also have a Clear CMOS jumper/pins (see page 49). So the stuff you did with the battery was doubly unnecessary. Oh well.

The problem seems slightly less severe than i thought anyway, since you at least get the F1 message and not a mere black screen, like you initially mentioned. Also, you have a Flash BIOS button + Flash BIOS USB port, and the Multi-BIOS switch. You should have no problems restoring normal functionality after all. Read the manual on how to do it, page 51 and if necessary page 67.

Aye, thanks for the help! I will try it again and keep you posted on how it goes! And keep away from stupid windows apps for the important processes, got it :D

And yep, the clear CMOS button appeared to do the trick-with a few caveats, however! It needed to be pressed for a considerably longer duration (almost an entire minute) while the PC was off, but with the power plug still attached. When it was shut down, the clear CMOS button was lit red, indicating probably that it needed to be used. When the PC was unplugged from the power source, the red indication went off (as expected).
Also, another important step was that the BIOS switch was turned to side B (side A is the default one, which was bricked in my case).
If anyone faces the same issue as mine, note that it may take more than one try, so don't panic just yet.
All in all, here are the steps I followed which did the trick:
1. Shut down your PC but keep the power cord attached.
2. Turn the BIOS switch to side B.
3. With the PC turned off, keep the clear CMOS button pressed for at least 30 sec (count them with a timer or smth).
4. Turn on your PC, and you should see your BIOS loading. If you get to the "Press F1 to enter setup" screen, rinse and repeat the above procedure (with the BIOS switch turned to side B, or the side with the functional BIOS in any case).

Do not forget to restore the corrupt BIOS, because if you turn the switch to that side, you'll face the same issue again!
To do so:
1. Download the latest BIOS version from the MSi website and save it in a FAT32 usb stick.
2. Turn on your PC with the BIOS switch on the functional BIOS side, and press repeatedly "del" as it loads to enter the BIOS screen (as you normally would).
3. Go to M. FLASH, locate your usb and BIOS version stored within, but do not start the procedure.
4. Turn the BIOS switch to the side with the corrupt BIOS (it's safe to do so here).
5. Begin the flash BIOS process.

And now you should have both BIOS sides working properly, problem solved.

Btw I wanted to ask something else if you have the time. I have a Thermaltake PSU installed and after I restored my BIOS, there appears to be some sort of confliction with the Thermaltake software I had installed. When I open my PC this message appears: "Could not setup a connection with power supply. Please make sure your Toughpower DPS is successfully connected to computer via USB."

First of all, is this something to worry about? I read somewhere that it may block the PSU fan from working. Possible solutions might be to just uninstall the software, but I also read in a Thermaltake forum that flashing the BIOS with the option to "Clear DMI data pool" solves the issue.
Is this option available in the M.Flash screen in MSi, because I can't remember seeing it.

No, the MSI BIOSes don't have that, at least i never saw it, and i had multiple MSI boards where i also updated the BIOS multiple times. It might be solved with uninstalling the Thermaltake software, rebooting, and installing it again. Otherwise, ask at the Thermaltake forum, they're bound to know more about that.

Never ever again update your bios through Dragon Center. I do not know why MSI even gives you that option. First download new bios to usb stick. Always before installing a bios update boot into the bios go to the section where you can restore defaults and exit. Do so and reboot into bios with the delete key. Then use M bios. Then M Bios will take you to new screen that should display your bios file , in this case 1A. Select the bios with you mouse and installation should proceeed.After bios is fully installed remove the usb stick and boot back into bios and set your memory speeds, timings , and voltages. Save the settinggs and reboot into the bios now set cpu voltages speed, and timings. Save and exit and reboot into windows.Done.
