@twometres Hardly any motherboard vendors/manufacturers have a fail safe plan for flashing bioses. Like come on it's mid 2019! not 1995. Just get a CH341a programmer. Back up the full bios using CH341a before installing the motherboard in the case and your set. No one should have to pull out there ch341a just to flash a modded bios that's ridiculous. Like I dont get it why motherboard vendors/manufacturers are blocking flashing modded bioses? They can get flapped i'm looking at you "AsRock". Like whats next I have to get a JTAG to install a custom rom on my android phone?

Thank god I returned my Asrock board in favor of Gigabyte. Had no idea there were so many roadblocks. Perhaps the modding section of the forum needs an Asrock specific unlocking pinned thread of its own. As far as MSI goes there are special premade ch341a cables with matching headers to the msi jsp1 motherboard headers. I picked one up last year from Aliexpress I think. So no need to use test clips.

@elitethem - if you have CH341A now, then you can do whatever you want on the Asrock BIOS too.

@twometres - yes, sometimes this is possible, rename BIOS to exact stock BIOS name (including extension) and try.

@davidm71 - it's new Asrock protection, and of courser AMD always more difficult than Intel to get mod BIOS in there. This is recent issue, UBU can remove old type, like Z170 and any previous

@Lost_N_BIOS That's very true mate. :) But what I'm concerned about is whats next? Maybe they'll start encrypting each main bios with a RSA4096 key say goodbye to modding community overnight. You have to stand up and say something get them back inline. Anyways I'm spamming the thread.

@elitethem - I know what you mean, hopefully that never comes to mainstream desktop motherboards! Some OEM's already do this, HP specifically and some of their stuff is worse than that (Sure Start), even with programmer it recovers stock BIOS after programming

@Lost_N_BIOS I hope not aswell mate. I believe AMI should (Open-source) there bioses technologies and the vendors/manufacturers should aswell. Microsoft are even getting onboard with open-source software I never thought that day would come. :)

AMI Make too much money from people to open source, some of their software is $5000-7000 per license. It would be nice, but "security" concerns I'm sure would never allow them to open up BIOS modifications on a wide-spread basis for all customers.

Is it possible to cross flash a bios from another mainboard vendor onto another motherboard from other vendor?

@davidm71 - yes, sometimes this is possible, if you have a programmer, or if forced in using various methods. Chances of it working are much lower than chances of it being possible
I've seen a several instances where this is 100% OK, but usually only on OEM type boards (HP, Packard etc), rarely on some mainstream boards and in those instances often certain things didn't work

@Lost_N_BIOS If they can get Coffeelake working on a Z170 I am sure it’s possible with the right conditions though level of difficulty be in the advanced to nearly impossible level I’m sure. Thanks.

Board layout and trace layout differences between boards is usually the major reason this doesn't work, aside from all the other hardware differences between each.

Hi guys! I think I finally found the right place for my issue. I would like to downgrade my ASUS ROG STRIX B360I bios to a lower version because I suspect the latest one is giving me issues with ram stability. The built in bios flash only allows me to upgrade and not downgrade.

Looking at the procedures form the first page, am I safe to use the same commands and AFU tools to perform for my motherboard? Any advice? Thanks!

@nnyymm - I assume you meant this board ASUS ROG STRIX B360-I Gaming?
Try the method >> "detected and published >here< by ValkyrieStar" If that does not work, try Ai Suite. /GAN is not suggested, unless you have a flash programmer in hand and a verified and valid backup made and confirmed as OK.
That method is for old BIOS/boards, and should not be used on new stuff, and only works with old AFU that's probably incompatible with your BIOS anyway.
For modern AMD Asus boards, usually you will have to get flash programmer like CH341A and SOIC8 test clip w/ cable if BIOS is not in a socket (Soldered to board), if it's in a socket you'll want to get a U Type Flat Chip IC Extractor as well

Please wait if you're reading this now, I may be able to help you tell the BIOS to allow you to downgrade, checking....

Hey! Never mind, this is Intel board, sorry, I thought it was AMD when I typed out above reply
You can use FPT, but you would have had to have made a BIOS backup previously with any of the older versions you may want to go to, so still stuck I guess, checking about my initial thought above, wait again
No luck in what I was thinking - what is the exact error message you get in EZ Flash?

@Lost_N_BIOS
Yep! That Intel board. Oh man, it looks like I’m out of luck. Why do manufacturer have to make bios downgrade so troublesome / difficult.

I was previously using a ASROCK AMD motherboard and downgrading and upgrading was a breeze. Ugh!

On EZ flash it just says that the bios is not compatible. Even though it definitely is. I guess they have a time checker something

What is the exact wording, show me an image if you can't remember.
