I updated the MC via UBU, the oroms etc.

Upon flashing and restarting PC no longer boots.
Flashing CPU light.

Can anyone check this bios and see what's wrong?

Lastly, I found a list of modded bios on the forum with latest MCUs.. Can you verify that this one is safe?

I ordered a bios chip as I don't think there's any other way to fix it without a SPI flasher.
-------------------

Reading other topics, people mention updating each microcode automatically causes the offsets to change..

CPU is a 2600k, I wonder if the offset for the IVB cpu is correct but SB is not.

@PhatAgent - You should have ordered CH341A + U Type Flat IC extractor instead, using new stock programmed BIOS chip you will loose your serial, UUID, and have to fix LAN MAC ID etc.
And, without programmer, you can;'t dump your old chip to grab original UUID from either. Do you have ANY previous BIOS backup, could be made with any program, at any time in the past? If yes, send to me, that will have all your system specifics in it, so I can fix proper BIOS for you.
You are correct, without flash programmer, you can't fix this due to this model does not have USB Flashback. Unless you have other similar Asus board with socketed BIOS, current bricked BIOS chip can be flashed via hotflash on another board, but it's not ideal and messy if it's not same model (We can fix later, but not ideal).

UBU ucode issue is probably due to padding added or removed above the microcode volumes (offsets do not matter). Would be waste of time to check, I will just make you proper updated BIOS.
What BIOS version do you want me to use to fix you a BIOS, 3603 (latest)?

If you do not have ANY previous BIOS backup, then please send me a zip of ALL stickers on your board, check side of 24 pin connector, top/bottom sides of PCI/PCIE slots, on/around the LAN metal block port (be sure to look on bottom of the block itself too)
Look on back of board as well, and don't forget the long skinny white sticker on side of PCB

* Edit - I checked the bad BIOS above, I can't see for sure what the issue is, no added/removed paddings, but I can assume incorrect method was used by UBU (Should be MMTool used, not UEFIReplace, because these are in PEI volume), and I can tell it was not done that way most likely, due to other alignment stuff

Please find a fixed BIOS here --> [OFFER] Asus P8Z68-V/GEN3 fixed BIOS 9903, modded with NVMe + others

@PhatAgent - Most of that you do not need for this board, but it will come in handy for you in the future with other boards.
Yes, you also need IC Extractor (U Type Flat IC Extractor) Best to get that on ebay for $1 + Free shipping, and then wait for the long delivery, vs paying $4-8 for shipped from Amazon

UBU decides often what method is used to replace microcodes, MMTool or UEFIReplace etc, sometimes for some BIOS this just needs done manually.
Padding stuff I mentioned cannot be edited, added, or removed etc by Hex editor. Sometimes you can update microcodes by straight hex edit, if they are in ideal location and you know how to do. In this case that should not be done either.
No, UBU is not always 100% OK to edit all BIOS microcodes, you have to check before/after BIOS with UEFITool 51+ and be sure everything is same in all edited locations (no added/removed padding in any touched volume), and that parser tab matches before/after, otherwise sometimes can = brick (not always)

You can use only one microcode in the BIOS if you want, and if it's correct one for your CPU, and if the edit is done properly.

@Lost_N_BIOS Just ordered the SOIC8 programmer, as you said I can use it for future boards. It'll be here in one day.

Is there a way to remove the socketed bios chip without the U type extractor? That will take at least a week to get here.

BTW you mentioned hotflashing a bios chip... Is it possible to use the new programmed BIOS chip to bootup, remove it swap the bricked one to reflash?

@PhatAgent @Lost_N_BIOS

This board does have BIOS recovery via USB. Please check the manual; alternatively, see the below:

1. Turn on the system.
2. Insert a USB stick with ONLY the BIOS file in root directory (I'd recommend using my modded one as it's newer and named correctly) into a USB2 port
3. Crash-Free BIOS Utility 3 should read the BIOS file and enter EZ Flash 2 utility automatically
4. It should then force you to enter BIOS setup where you can enter <F5> to load defaults initially, then restart to configure as you require.

Make sure the first thing you do (if required) is upgrade ME to the latest as per my instructions.

Hope this helps!

@PhatAgent - Yes, it can be done without extractor, but it's SUPER easy to bend the legs terribly bad, or break them etc. Best to wait.
Yes, hotswap is just like you mentioned. Boot with one BIOS, get into EZ Flash or windows, then remove the BIOS chip, put in other one, then flash BIOS.
If you do anything like that, try to make a backup first, or wait on your programmer to make backup, before you do anything to the original chip, that way you can preserve your original UUID and it's easier to put all sys details back into proper places in proper format etc.

@Iken I'm not sure the crash free recovery works in my situation..

Video tutorial here shows the PC booting with an error message saying the system has went into recovery mode..

I boot mine up and it just flashes the CPU led on the board. Never posts or anything. I did try plugging the USB drive with nothing on it other than the bios with no luck.

Steps tried, powered on for several seconds, plug usb into rear USB2 ports. Waited several mins with nothing

@PhatAgent

That's unfortunate.

Using UBU, I just compared the BIOS you attached and the MC layout is absolutely identical to mine so I cannot understand this problem at all.
I also checked the NVMe insertion in UEFITool and that appears fine too.

Have you tried a Clear CMOS?

Failing that, could it possibly be the CPU has gone faulty? Do you have another you could try?

@Lost_N_BIOS Hey, I have the programmer.

Think I have the DIP-8 Bios chip in correct. The indent on the side is pointing to the right which I believe indicates Pin 1 is above it. it is plugged into the 25xx left side.

Do I have do mess with the jumper pins or is it good to go?

What program do you recommend I use to reflash it?
------------------------

@Iken @Lost_N_BIOS

Update. Got the SOIC8 programmer, had to modify it to supply 3.3v on the IO pins instead of 5v as others have mentioned.

Was able to flash the bios you provided. Everything seems to check out. Booted up first try.

Thanks for your help guys, appreciate it.

@PhatAgent - Glad to hear you are back in action now, good work!!
But, not sure what BIOS you programmed in? Did it have your serial, UUID and Ethernet MAC ID?
If not, and you need me to fix, hopefully you dumped your chip with programmer before you erased or wrote to chip! If you did not, did you make any software backup of BIOS at ANY time in the past?

Probably recovery method failed due to incompatible USB, Asus USB recovery and flashback is VERY picky about USB sometimes

I dumped my failed bios and flashed the bios iken listed above.

Everything seems to work fine but I will confirm if the serial etc transferred over or was lost

He linked stock edited BIOS, so no your serial, UUID and Ethernet LAN MAC ID all would be missing since you programmed that in with flash programmer.
It's all OK to not have, since you can't RMA now, except for Ethernet MAC ID, if that is stored in BIOS and not on Ethernet chip FW, then your Ethernet will not work until you fix it.
We can fix this stuff with FPT software now, so you wont have to use programmer again, unless using programmer would be easier for you than learning how to use FPT, if you don't already know how to use it.

If you mean you dumped your "badFlash.bin" as in the file at post #1, this is not a dump, that is a stock edited BIOS (That you may have later dumped, if you programmed that in with programmer).
When I mentioned dump, I meant dump with programmer now, after the bad flash and BEFORE you did anything with programmer. << This is the only file that will have your serial, UUID, MAC ID all in place and original. Or, any previous BIOS backup you made with any tool, BEFORE this happened.

@Lost_N_BIOS

I dumped my original bios with the programmer program before I erased the chip.

I assume it has all my information on there.
Let me know if it looks good and we can transfer the data to the stock modded bios.

If not, I can learn the software you mentioned.
