Samsung Venus2-13_MAIN Rev 1.0 MB Model: BA41-02944A bios needed

[zabounis]

Hi, i have extracted the bios from a Samsung NP930XED (model Venus2-13_MAIN Rev 1.0) MB: BA41-02944A . The ME analyzer reports Error: Unsupported Intel Engine, Graphics and/or Independent firmware!
I cannot find a working bios, or someone could clean the error of my dump.
Could someone please help me.
Thanks in advance.

If you see a request that doesn't follow the Forum rules, please don’t follow up on it
It's against the Forum rules (they must first include the Serial Number, Service Tag, SNID, etc.)

Thanks you for your help.
I tried it, and the laptop does the exact same thing. Power's up, fan spinning, blue light blinking constantly, no post, no image, no backlight. It power cycles every 1-2 minutes. Keyboard backlight turns on and off every 1-2 minutes.

I tried your modded bin in ME analyzer and gives me the same error as mentioned above. I don't know what to tell...

Users with worn-out or torn stickers usually mention that in their first post
That way, I can provide them with the actual Serial Number. The SN is 5SU49FCT500035D
Try the file Shiyab provided and see if it works. If not, I will make a new working BIOS file for you myself

To be honest, I saw that he went to great lengths to provide enough information to help me, and he made his request respectfully... unlike other users who ask for help demanding it...

[Sparo]

I know he's nice and respectful, so I'll do my best to try and help him
But rules are rules. Everyone, including me, has to follow the rules (SN is mandatory)

Back again. I tried Shiyab's bios. Same result. Turns on, blue light blinking, power cycles every 2 minutes. No post.
First of all i appreciate deeply what you're doing here and i'm glad i'm part of this community.

I tend to believe that might be something else wrong with the machine...

I will try another bios (if provided) then i will call it "no fix".

Alright, try this BIOS file and See if it works, Good Luck!

No luck.
Flashed both main bios chip and the secondary EC bios chip with the files provided by Sparo. Same result.
Probably there is a problem with either one of the memory chips or the CPU/PCH chip itself. There is no other explanation.

Guys thank you very much for your effort. There is nothing i can do more, unless you have any crazy idea i should try ...

What markings are printed on the EC chip? Try flashing back your original EC firmware first and See if it works
If not, try erasing it and writing all zeros to it to see if that triggers something. Give it some time after each attempt

[zabounis]

The secondary bios chip is marked W25Q80DV

thats the one i flashed with your 128kb bin file. The programmer filled the first part leaving the rest empty. Total size is normally 1024Kb.

If you mean the SiO chip, i have't touched that. I dont have a vertyanov or similar programmer to try..

Yeah that's the actual EC chip (The SIO)
The one you flashed is probably the Thunderbolt EEPROM (TBT Fw) or the USB-C PD chip
I'll see if I can find it for you to rule it out as well. In the meantime, flash back your backup of that chip

[zabounis]

ohh i see...alright i will flash back the original firmware of that...in the meanwhile the USB TYPE-C charging is working flawlessly. The laptop charges fine. Even with the wrong firmware. So i don't think this is going to make any difference but i will try it.
