Broken APEX49 Posted April 28, 2021 Posted April 28, 2021 Help me I changed 0098 to CAP name M12A and flashed back, but it did not start. Are you making a mistake? Did the BIOS get corrupted? CPU is 11600KF Quote
Broken APEX49 Posted April 28, 2021 Posted April 28, 2021 If you change to BIOS2, the motherboard will turn on, Since the BIOS does not support 11600KF, it is natural that it will not boot, right? Is BIOS1 broken? Quote
Achill3uS Posted April 28, 2021 Posted April 28, 2021 try to flash again 0098 to bios1 from clean pendrive via usb flashback https://www.asus.com/support/FAQ/1038568/ Quote
Broken APEX49 Posted April 28, 2021 Posted April 28, 2021 I returned the CPU to 10900k and booted with BIOS 2 without any problems No response when I press the power switch on the motherboard trying to flash back the initial BIOS 0607 to BIOS 1 and boot it 1 Quote
AKM Posted April 28, 2021 Posted April 28, 2021 Tested 11900K cold on 12 Apex this past couple days. Thought to share my experience. Starting voltages given in 13 Apex thread also work for 12 too. Tried IO voltage at both 1.5 and Auto and didn't notice difference but besides that very easy to run full pot on this gen as well. Used 2101 BIOS for testing. TurboV linked in 13 Apex thread though is very hit or miss. Works well at full core/HT on but dropping cores to 4/4 or 3/3 it would freeze system every time. Work around for me was to use older TurboV to set voltage and then use the Worktool or XP Tool given in 13 Apex thread to set core/cache clocks. 2 Quote
Broken APEX49 Posted April 28, 2021 Posted April 28, 2021 I'm saying the BIOS can't be rewritten Even if I can't even open the UEFI screen and talk about voltage ... 1 Quote

I had the same issue on my XII Apex, couldn't fix bios 1 so I rma'd the board. Issue started after I updated the firmware to the most recent firmware. I know at least one other person this has happened to. Edited April 28, 2021 by Midnight703 1 Quote
Broken APEX49 Posted April 29, 2021 Posted April 29, 2021 Isn't this BIOS update not covered by compensation? Quote

My board won't turn on at all with bios 2 selected (Start button does nothing nor jumping) pretty sure it started when flashing 0098. Funny thing is I can use USB Flashback and it goes through the flash process so no idea what's up. Must be some sort of bug because I can see it when using FlashROM/Rasp Pi 1 1 Quote

Must be some sort of bug because I can see it when using FlashROM/Rasp Pi I have this exact same issue on bios 2 with 2101 bios. I heard we need to use cometlake cpu to be able to start and updating ME. But currently dont have cometlake in hand i cant testing this. 1 Quote
bscool Posted May 1, 2021 Posted May 1, 2021 (edited) I posted about a bug where flashback does not update the microcode(note this is on z590 Apex). Possibly related to that? To update the microcode you need to be in UEFI and use EZ flash. https://rog.asus.com/forum/showthread.php?123935-z590-bios-update-possible-issue-check-your-microcode Edited May 3, 2021 by bscool 1 Quote

chispy Posted May 2, 2021 Posted May 2, 2021 Any new incoming bios for rocket lake that won't brick the board ? I have a friend who brick his board too updating to 2103 for RKl cpus ? I want to test a 11600k on Apex 12 but i do not want to brick the board like it happen already to a lot of people . Any kind soul in Asus please fix this bios corruption bug ... 1 Quote
Rauf Posted May 2, 2021 Posted May 2, 2021 (edited) It doesn't brick the board. But you have to be more patient than normal on first boot. It does some update with black screen that takes a while and looks like it hangs. If you wait it will eventually reboot and work normally. Don't reset during this process! You can update bios with externa flasher if you have bricked bios. Edited May 2, 2021 by Rauf 2 1 Quote

Because on bios 1 im updating to rkl beta bios with 10900K back than. Quote

I just tried this with 10700k and 10900k and still no difference than with 11600k. I probably have to flash back to an older bios first or something as it's certainly just a bug BIOS 1 is 2103 and I've tried flashing bios 2 with 2103, 0098 and 0088 I believe. In bios the 11600k shows 3C and the 10700k shows E2 I think. What's wierd is I only used bios flashback up until a couple days ago on this board so somehow the code did update doing it this way. Sometimes after bios flashback I saw "updating Aura firmware", "updating me" and the long blank black screen too Edited May 2, 2021 by GtiJason 1 1 Quote
