2.10 bios update killed Z68 Extreme3 Gen3

[khel]

I have i5 2500k CPU and Z68 Extreme3 Gen3 mobo. Everything worked fine until I've decided to update bios to 2.1 in hopes of changing CPU to IB in near future.
I've used USB memory stick to flash it. It went without a hitch and it did say that "... update successful - press any key to reboot". So I did and that's when all the problems started.

It wouldn't POST. Just powers on and in a couple of seconds powers off, then powers on again and off - the cycle continues endlessly :/
Before it powers off dubug shows code 59.

I unplubbed it from the wall... I've tried to clear CMOS with a button, jumper, by removing battery - nothing helps.

I've never had problems with officially released BIOS updates before this MBs.. :(

Any other ideas?? Or RMA is the only option?

Try an extended cmos clear with the power supply unplugged from the wall outlet, jumper the cmos clearing pins and remove the motherboard battery.
It might be successful after 30 minutes, a couple of hours, or possibly after 8 hours or longer.

Make sure that all your wires and cables are secure and that all hardware is fully seated.
Try booting with a minimal hardware setup where your only goal is to get into the bios.
Disconnect all hardware and cables that aren't needed for entering the bios including:

• all disk drives (ssd, hdd, usb, optical, etc.)
• all usb devices except your keyboard and mouse
• audio and network cards
• front case usb, audio, etc. wire connectors to your motherboard

boot with only one memory module installed
It's possible that there is a coincidental failure with your power supply.
If all else fails, you should remove your motherboard from the computer case and set it on a cardboard box beside you computer case and repeat these tests.

Can you borrow another psu, memory or cpu to test with?
What brand/model number is your cpu heatsink setup?
Have you made any recent hardware changes to your system.

Did you removed then pendrive from USB? If you did then it is your fault. After reboot there is another part of flashing (Intel ME Firmware from ver. 7 to 8)

Hmm.. I think that's what happened. I did remove USB drive.. Though I don't see where it is my fault as nowhere was it mentioned not to :( When I'm told that "update successfully completed" - I rightfully assume that it is indeed completed ....

Anyway, I'm going to try "extended cmos clear" etc. Though something tells me that it's not going to help.

Thanks

Oh really? And what about fact that you have to read a warning before downloading UEFI from ASRock website:

Note:
1. To support Intel's 3rd Generation (Ivy Bridge) CPU, corresponding BIOS, drivers, and AXTU update are required.
2. After updating BIOS, please press any key to restart your system. At this moment, please do not remove the USB flash until Intel ME F/W update is finished.
3. After you finish updating this BIOS, please reboot your system.
4. Please only flash newer versions of BIOS in the future.

So next time read carefully.

Hmm.. You are right. Must have missed that part :( .

Well, now the question is - can it be fixed?

If your still running a Sandy Bridge CPU probably the shortest way to roll back to a "working UEFI" is to order a CMOS chip from badflash.com pre-flashed to the earlier UEFI that worked on your rig, and swap out the chip.
I have not read of anyone sucessfully updating to these Ivy Bidge/Sandy Bridge UEFI updates EXCEPT for radier...

Many users on polish forums have no issues just like me.
One guy have same board and same CPU as me and yet he reports locked ratio and RAM frequency at 1333MHz.

I think all problems are users related (great example we have above) because I don't belive that mine P67 Extreme4 works like a charm and other identical board after flashing have some issues.

Judge it by yourself.

Thanks a lot SaphireX! That's what I thought. I've found one on ebay, hopefully that'll work :)

p.s. looks like I can get a new bios chip directly from asrock for $15+shipping

Did you tried to boot your PC with that pendrive and UEFI on it?
