@Frixx - Nice, all is unlocked then, and nothing more you need to do to be able to flash in mod BIOS
Ohh man, that is VERY limited BIOS!! I wonder why there were so mean to customers like that?!?
OK, I will unlock BIOS for you now, give me about 10 minutes maybe

@Frixx - On your Main BIOS image, is that showing all, you can't scroll down and see anything below "Memory Freq"?

Yeah it so very limited BIOS config. i dunno what make them decide on the kind of BIOS setup, i been searching some hidden setting like key to unlock the hidden setting but no luck :(
And the bottom part of the MAIN is the ME info, ME fw Verion and ME FW SKU

Yes, no reason to limit BIOS so much! Even in the visible menus they gave you, plenty of settings is hidden that should be user accessible
Thanks for the info on Main, I assumed you could see ME FW, but wondered about Lid Open option, but I now see this also in original Advanced, so I will make visible to you there.
I'll edit menu so you have Main, original Advanced + Hidden Advanced, Chipset, and original Boot + hidden Boot, Exit

----------------------------
@Frixx - Here you go, flash it back via >> FPTw.exe -bios -f MachbiosUnlock.bin

Some settings may be duplicated in places, I didn't spend time to check, but you can set either place if you see this and it will be OK and same/same no matter where you set it from.

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user Frixx at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not Frixx, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

Hi

Im able to flash the bios and everything works well and thanks for your time and effort. I have some question, Is it okay to modify the configuration of the bios direclty (desired configuration) without showing in the BIOS section? Actually while waiting for the modified bios, im experimenting using this AMIBCP :)

@Frixx - You're welcome! Great to hear all went smoothly, thanks for quick test and report back! So, you have new Advanced, Chipset, and you see new stuff in old/original Advanced too, correct? If yes, great, thanks for confirmation
I'm not quite sure what you're asking there, can you please explain differently? Please note, I did not make any edits to this BIOS with AMIBCP, it may or may not be OK to edit the BIOS with AMIBCP, if you already have before and flashed it and it didn't brick then all OK

I'm saying is to modified/edit it direclty without exposing the hidden setting in bios and i've tried modifying the OPTIMAL but its not working. @Lost_N_BIOS i'll stick on the unlock bios to avoid some problem :) Thanks

@Frixx - Yes, you can modify settings directly, but AMIBCP may or may not get it all correct, it usually does though.
Do you just need a few settings changed ONLY, and do not want all that advanced menu unlock stuff? If yes, tell me the exact settings you want changed, and what you want them changed to, and I can make you another BIOS with only those changes made in all possible locations (so it will be hard set, current and default)

@Lost_N_BIOS - Welp, I guess I've done it and I think I bricked my laptop from trying to adjust the memory timings. The laptop just lights up its power indicator and spins its fans for a bit, but that's it. So I tried resetting CMOS by removing both the laptop and CMOS battery connections, then pressing the power button for a minute before connecting the batteries again then restarting, but then it didn't work (still just a black screen) . Panicked, I went and borrowed the ch341a programmer with the soic8(sop8) from my friend and got his help to identify my BIOS chip (G25B127D). I'm using AsProgrammer 1.4.1 to read the chip, and did only that because I don't know what to program my BIOS chip with. So all I did so far was just read the chip and save what was read. Thus, I just made a link below for the: 1) biosreg.bin file that was initially dumped before when everything was stock; 2) the MainDXEMod.bin file that you sent me last that worked and allowed me to adjust the memory timings; 3) the bin file that I've saved when I had the ch341a read the BIOS chip; 4) the BIOS download that I've downloaded from mechrevo website that I don't know how to use in this case because it looks like it has to be used within Windows; 5) and the picture of my BIOS chip. May I ask for your help this time for what I should put in my BIOS chip so that it would go back to how it was before (stock at least)?

@Lost_N_BIOS, thanks anyway and also i dont have that clip flasher thing

@Enab - Sorry to hear! I will check your file and fix for you tonight, sorry I don't have time right now as I'm heading out the door in a minute. Do not erase or write to chip yet.
I am on limited internet, please just upload your dumped BIOS from programmer for me, I do not need the other stuff you mentioned including in above link (I already have all that).
Ohh, you have stock BIOS exe/package for this model, also please include this so I have for later (don't need to fix, just so I have it in case someone else needs later)
Also, please upload to uploadfiles.io or some other free host, zippyshare is often plagued with viruses, thanks
I will make you BIOS with last changes we made, all working and fixed, back to how it was (unlocked) before the memory timings messed it up

@Frixx - You don't need flash programmer and clip if you want to do what I mentioned at post #502, just need to reflash back to stock BIOS or a new BIOS I would make you with changes however you wanted them

@Lost_N_BIOS - Man, I'm really sorry for the bother. So, no problem if you take your time. Anyway, yeah, I haven't done anything yet but read the chip since I thought that I had nothing good to program in it anyway.

Eh? I didn't know that about zippyshare. Thanks for the heads up. I've uploaded both files you've asked for in uploadfiles.io as instructed (the .bin file and the .rar containing the .exe program).

https://ufile.io/f/4uer4

I do hope the laptop can be extricated from this. Memory timing adjustment used to be easy. Now it's become rocket science for me. Sheesh!

Hi @Lost_N_BIOS

I'm ok now with the unlocked bios hehe. Thanks for your time.

@Enab - Yeah, zippy often sets of several virus/malware apps any time I go there, even with ad-blockers enabled.
It's just a pain to tinker with timings on laptop when you can't easily clear CMOS and they don't auto-recover to fail safe easily like desktops do (not sure why!)
Yes, don't worry, you can save it

Here, program this back via >> Open app >> Hit Unprotect Icon (not dropout menu, just the lock icon) >> Erase >> Black Check >> Open BIOS file >> Write >> Verify
If it fails to start after that, please repeat this process exactly, then do not power on, instead do below and send me the file to compare vs the file you wrote (or you can, compare in hex, should be 100% match, otherwise there is a write issue)
>> Close app after verify above >> Open App >> Read >> Verify >> Save

If you do end up with issue and having to redo write and compare and it is a 100% match, then I will clean and update ME FW for you, it may have been corrupted on save or due to memory glitch etc. I did not touch it right now, quick check and it looked OK so I left as-is for now.

@Frixx - OK then And you're welcome!!

@Lost_N_BIOS - Yeah. I guess that's the difference between desktops and laptops. Or, it could be that Tongfang just saved money for their motherboards to do away with the fail-safe features, who knows?

Anyhoo, I have done as you said and the laptop still just powers on and spins its fans then does nothing. It's still just a black screen, even after I had the program write the fixed version in the chip.

So I did your subsequent instruction to redo the write, then tried comparing the .bin file you sent with the .bin file that was written in by the programmer, by opening 2 instances of AsProgrammer and putting it side-by-side. From what I saw, it looks like that the 2 files are the same. Although I am not 100% sure they are the same, because of the eye challenging comparison of the long files, I think I can say that I am at least 95% accurate when I say that they are the same (of course, a program to compare the 2 would probably be nicer and more accurate, I guess).

Below is the file I wrote in the chip.

@Enab - Many laptops are like this, for some reason!?

Please redo the write/dump exactly how I outlined it. No side by side opening of programs, or two instances of anything (close after write, then re-open)
Then send me the dumped file and I will compare it for you in hex editor. The file has to be 100% exactly the same, not 95% or close etc, that would be a fail and system would not start
