[REQUEST] Lenovo B50-80 (A8CNxxWW) BIOS Unlock

[justMaD]

Hi there.

I recently got an HDD caddy so I could extend the storage on my laptop, but unfortunately the second drive isn't recognized within BIOS automatically and since it's completely locked down, I can't change anything.

It would be awesome, if someone could help me unlock the real settings

Here are my results and the firmware installer for the version I have (since the lenovo site seems broken right now):

As well as screenshots of the current "options":





Thanks!

Hi mate,
We get . . .
Error 280: Failed to disable write protection for the BIOS space!

So your Eeprom Chips is Write Protected and only the Tools (SPI PGM + Clip)
can do this job . . . look here :

If do You want to rewrite back the Bios Mod get the Tools and I will help You !
Let me know

Oh boy, I already feared it would get more complicated than just flashing a new BIOS via Windows...
Well, I'm off to ordering the stuff... see you in a month or so, when the stuff arrives

Edit: actually, I'm only ordering the clip, since I should have enough methods for SPI programming lying around already. I got some arduinos and flashers and if that fails, also RPis and Beaglebones

Hi mate,
You are a Bulldozer and make me surprise
I think that They will be enough to make anything using FlashRom !

So it took 2 months to arrive (Note to self, don't choose sellers with Malaysia Post ^^).

Just arrived and I guess I'll have some time today to try and dismantle my notebook to get to the bios eeprom... Any Idea where I might find it?

[BDMaster]

Yes mate,
You have to look for ENE Chipset and near there are the Eeprom Chips !!!
Please make good MoBo pics on both sides and upload them here so I can see to
and find the chips !!!
Regards

P.S. There isn't any info on internet !

[justMaD]

Yeah, I'm searching for info right now and there really isn't much.

There are some SOIP-8 chips that I can see, but I'm suspecting one of them especially.
It has some numbers, but even with them it's hard to find something. It seems to be a SPI flash, though: 25b64bsig


The others seem to be mosfets and other regulating stuff (they're also close to the power input).

Does this look like a successful/usable dump: https://www.sendspace.com/file/wud1q8 ?

Donate to me for my work and time . . . look into my Signature

Yep, after a few tries of writing with some different chips selected (because this one was not available in the list), I could write and verify the writing successfully.

I now have a ton of options, but they don't help me solve my original problem of the HDD not being recognized in the ODD slot :/
Anyway, you've been awesome and did what you could, thanks!
