[REQUEST] Hystou S200 BIOS unlock

[stenor]

Hey

I recently bought this mini-pc, Hystou/Eglobal NUC-type pc.
This is not the first one, I have an older model as well. Nice fanless one. That bios was totally unlocked though, from the start.
With this new one there's almost nothing to do in the bios at all, never seen such a restricted bios before I think.

I want this unlocked for a number of reasons, including fan control and cpu/ram OC/control (supported by chipset).

Btw, I was reading here and on win-raid these hystou has a broken ME region or something, well I can say this one also shows
nothing in ME version string (also on the older model I own). Strange thing though I don't think I need it in any case.

This model is very recent, with a bios version of 12/26/2018, and I noticed it contains newer modules for intel RST and VBIOS
than is available in UBU.

I've attached two FPT dumps, one bios and one full dump (and a hwinfo report, just in case it's useful).

PS: I also tried to unlock myself but I got this "saving secure rom as unsigned" so I wasn't sure if that was ok and I didn't want
to deal with a brick or some problem.

hI~~ i have a question.
When you re-flash a mod bios that you custom ,does this NUC pc still boot normal???

By i know, the NUC series usually contain a secure protect ,when we flash any modification again ,it will get black screen ,even if we only change one byte .

So ,before you have ability for recover bios ,don't do any things.
Unless you can confirm that when you re-flash mod bios the machine still normal boot.

This bios can be unlock two tab "Advanced " and "Chipet".

Well, I haven't tried on this new pc yet, but the previous one I mentioned, that I've modified
myself the bios. No problem, dump and flash with fpt, no protection to circumvent or anything.

This one is the same brand and type of pc, I assume it'll be the same.
Also I think it's not really a NUC except in formfactor. I mean, it looks like a NUC to me, but I
don't know if it follows any intel specifications or something.

I also should have a programmer + clip in the mail soon, btw.

Edit: Only adv. and chipset? I was hoping for "Global Acoustic Configuration" at least.
I'll settle for what's possible of course though.

Thanks.

I have not tried it yet. I was thinking it's best to wait for the programmer to arrive.
Though I'm curious if the full 8MB FPT dump is the same as if I used the programmer to dump it ?

If so I could safely try it now I suppose, as I'd have a good backup.

You are right~~
Safety is the best important thing,the dump bios from tool or from a programer i think they are some part were different.
Even use ftp dump bios or afuwin dump bios ,the data also not 100% the same that if we compare them by hex mode.

Hi, I asked the Aliexpress seller of mine for an unlocked BIOS Update and they provided a new version from October but unfortunately it's still completely locked down.

Here's the download: https://mega.nz/#!t5QFjagb!pjzElejgwIFO3...RvpxrWG8Vs

Has anyone had success with the unlock? I'd really like to tweak the fan a little bit as it seems to have a lot of headroom.

Thanks Genius,

I'd love to try it, but have you tried it before and did it work?

Can you confirm it'll also enable IMEI?
