Help w flashing dsanke bios for p775-dm3

[papjco32]

Hi all. I recently got my hands on a p775-dm3 and i tried to use this:

to flash the dsanke bios for my machine. I used the p7xx-dmx 0729 file from here: https://github.com/supermarsx/other-clevo-modded-bios

now the laptop refuses to post. I have a ch341a programmer and using the CH341A_CH347 Programmer V2.0 program i was able to flash the backup i made before it went down, but no dice. Also tried flashing the 511 ver of dsanke and no dice. Tried the bios from clevos website, no dice. Let me know what I'm missing here, i honestly just wanna flash the stock bios back rather than dsanke, trying to install the dsanke bios bricked it so i don't know. Any help is appreciated. Thanks, Jon

update: flashed the wrong chip. i was flashing an 8mbit chip over by the usb, hopefully its ok. found the bios chip backed it up, and then flashed the backup from earlier to no avail. also tried the one from clevos website, no dice. when i flashed either one i got this error:

Verification error on address: 0x00000032, Device: 0x8C, Buffer: 0xCC

 

i also switched to neoprogrammer to see if it would make a difference. it didn't. i will continue to use it it provides a lot more info.

You need  to flash this with programmer.

i did using the backup i had and the official bios from clevo. I'm pretty sure i need the contents of this chip (see attached pic, in blue) as it is the chip i flashed and (like a dum dum) didn't take a backup of. a source of that would be great. on a different note, what do i need for the machine to start properly? I've been testing with cpu gpu mobo heatsink ram power button and sdd, do you need more than that? Thanks for any advice, buying a $250 mobo from aliexpress does not sound great to me lol

You need to find someone who has a P775DM3 and is willing to make a backup image from that chip for you. Try asking in the P775 subforum.

So I bought a replacement motherboard from ali-express, hoping all I have to do is copy the chip to get old one working again. If not I will just replace the motherboard. With that being said, i have a qtj1 (10th gen es) CPU that I wanna use, so where do I get the intel me disabled dsanke bios @runix18? (As far as I know this is the one I need)

Also, do I need to cover any pins for that CPU? Reading different forum posts here it seems like you don't need too.

Thanks in advance for all the help.

Here is the bios. As for the mutant CPU you do not need to isolate any pins.

So I got the laptop to POST (yay) flashed the bios (it now says clevo flashed by dsanke or something like that for the boot logo), tried to put in the qtj1 cpu and it wouldn't fit. so i delided it and that made it fit but it wont post. i tried with just one stick of 8gb 2133mhz sk hyniks (this same stick works w my 7th gen i7) to make it wasn't ram and it still didn't post. is this something i need to ask @ViktorV about? also i bought a b173han05.2 display and i guess i got the wrong cable, i bought https://www.aliexpress.us/item/2251832620880374.html?spm=a2g0o.order_list.order_list_main.29.51be1802Xm5ZCE&gatewayAdapt=glo2usa  (P775 40P 0.5mm 46cm) I'm guessing i needed "P775 40P 0.4mm 46cm" instead as the one i have is too big of connector. (is this a good price? if not can you link me?) Thanks in advance 🙂

well i flash that zip linked above and it says "ME FW Version: 61665.9.41688.14353" in the bios i thought i linked to that picture, my bad right one is below

[runix18]

ME FW Version: 61665.9.41688.14353 - that number is an error number shown by bios because of me disabled modules (meaning no such me number exists).

do you have any idea why it wouldn't post the qtj1 cpu then?

[runix18]

Does it work with a regular cpu? does it post?

I dunno then. Bios wise it have been made by dsanke specialy for this mutant CPU. If everything is rulled out the only thing remaining is the CPU itself.

One strange thing I saw a while back working through some of these with BIOS mods - Occasionally after flash / CPU swap / GPU swap, the unit absolutely refused to POST. Pressing and holding FN + D on the keyboard for a solid minute immediately after pressing the power button has helped many times!

hey all i recently replaced my screen with B173HAN05.2 and no longer get display in the bios. it works 100 percent in windows 11, but in recovery or bios its just a black screen. any ideas? thanks in advance.

Maybe a GOP update will help?

what is GOP update? and do you have links on how to do it?

Good job, you just needed a point in the right direction.

Well. That 0729 BIOS from Dsanke was migrated from TM machine with Z370. To flash it using fpt in OS on a DM machine with Z170, you need to

 

1. flash without your battery using only the power cord, and

2. unplug the power cord after the flashing. DO NOT restart with power. 

3. connect the battery and power cord back and boot the machine.

 

According to Dsanke, this is an issue with different BIOS structures. In Z170, it is "3MB Flash Descriptor + ME Region" and "5MB BIOS Region", while in Z370, it is "2MB Flash Descriptor + ME Region" and "6MB BIOS Region". If the system reboots or turns off with power, the NVRAM part in the BIOS will be messed up. Dsanke has a very detailed "readme" in Chinese about how to flash this BIOS, which the repository on GitHub doesn't have. For reference,

http://www.smxdiy.com/thread-3097-1-1.html

 

I confirmed this last week (in a hard way). Flash it with a ch341a programmer, or flash it in OS and then cut the power.😉
