hey @Lost_N_BIOS thanks for the reply!
come on man!, you always answering before reading the whole post :V

yeah i dumped the chip using the programmer and its software also using onother laptop ,(i provided the dumps as an attachment in the last post , file name is lenovo second chip.bin ). the dumps is saved in the other laptop too in case something happened i can rewrite the original data ....

do we still need the old files the we dumped before ?


i just posted on the bios-mode.com site and i waiting dudu's answer

I know, I reply as I read, and then talk too much, so don't want to erase all I wrote by the time I get to the end
Yes, keep FPT backup too, in case programmer dump is not good (looks OK though )

hey @Lost_N_BIOS
after i got my laptop bios advanced menu unlocked , i found out that i cannot change most of my cpu settings due to corrupted ME data (as what you told me before) and you might be able to fix it for me and give me some extra tweak abilities to the settings .
i dumped my bios file using the SPI programmer with my current settings to this file at the attachment :
plz take a look at it


additional informations :
lenovo legion y520

Intel ME Version: 11.8, Build 3510, Hot Fix 55
Intel ME Recovery Image Version: 11.8, Build 3510, Hot Fix 55
Intel ME FITC Version: 11.8, Build 3399, Hot Fix 50

Well, since you kept wanting me to just fix the ME FW on the unlocked file instead of sending me a new/current dump, I assumed that was what you wanted in PM....
So, I fixed the original unlocked file and sent you in PM. Do you now want me to swap that ME FW and unlocked FD to the above file instead?

* Edit - the dump above is not a new dump, this is 100% match to the unlocked file you sent me on 4/22, so the above file is already modified (unlocked FD and fixed updated ME FW), sent to you in PM about 10 minutes before this reply

Hi I am new to Bios modding but know a bit. I want to get my Bios modded to get advanced options to change ram timings and overclock it. I have the .fd extracted from the latest Bios .exe . Please somebody help me do it. I don't want to open my laptop and to deal with spi programmers. Please suggest a software only way if possible.processor is i7 7700hq . Link to Bios exe- https://download.lenovo.com/consumer/mobiles/4kcn45ww.exe
Please list all the necessary steps. I am a beginner.

i have linked the biosreg file based on reading answers on the forum - https://drive.google.com/file/d/1PWFp4WK...iew?usp=sharing
Edit: I tried flashing the dump and got error - https://drive.google.com/file/d/14CzH2kN...iew?usp=sharing (screenshot attached)

Thanks

@intello - moved your request to another thread already created for this model. As you can see here, flash programmer is required for this model, example items required are linked at post #9 of this thread

Thanks for replying but my model is different from the one previously mentioned and the bios is also different I think.

@intello - How is your model different, it's Lenovo Y520 correct? And it's full model is what you used in your original title which I left in placed, y520-15IKBN, correct? If yes, this is same/same, everything you see in this thread applies to your system
I can unlock this BIOS, but you need flash programmer to program it in. So you need to get those tools, dump BIOS and send to me, then I unlock and you program it back.

Ok I'll check and tell cause I am a 16 year old whose dad probably won't allow that. :()

@Lost_N_Bios can u send me H20UVE versions too that you sent to zain.dev so that I too can check for myself. Thanks

@intello - Well if you are not allowed, then nothing you can do until you are in control of the situation

H20UVE here, but it wont help you with anything, unless zain.dev was doing something wrong. This is used to dump and then unlock variables, which we already tested out on this model and it didn't work
http://s000.tinyupload.com/index.php?fil...732875438124725

Dump vars with all versions using command below, then copy folder and delete everything out except the vars.txt and send to me, this way all vars.txt is kept in place with the version that created it
H2OUVE.exe -gv vars.txt

@Lost_N_Bios this is the file i got no error and keyboard freezes for all except last one(i.e 5th one), 1,2,3,4,5 at the end of vars is in the order of the H20UVE Version you sent like 1 for first folder of version. please check and tell.

@intello - Keyboard freeze is not relevant here. Sounds like you messed up the files, please redo and then re-upload exactly as I mentioned, so vars.txt are inside the version folders that created them and there is no mix-ups (or can = brick)

Sorry here you go with the correct zip, also what about biosreg.bin i only got flash error and i saw u talk about that error to mitchgaming in another tread check my first post for the screeenshot of the error.

@intello - BIOSreg.bin comes next, after I edit vars for you, then you flash it back in, then you make a new Biosregnew.bin file. Sorry, not sure what other thread you are talking about for image of error, but it does not matter right now anyway, only what error you get after unlocked vars matters
Here, program this back in using the command below (there will be errors/success in a long list) Copy varsm.txt into the 100.00.16.08 folder which contains it's EXE, then run command below
http://s000.tinyupload.com/index.php?fil...500002922846995

H2OUVE.exe -sv varsM.txt

Then reboot, and dump BIOS region again using new name (FPTw.exe -bios -d biosregnew.bin) and then try to flash it back (FPTw.exe -bios -f biosregnew.bin) << There, if you get error 28 you have to get flash programmer, or do pinmod (both require opening the laptop up)
Or, if the above fails, you can try one last thing maybe we didn't test here. Put System to sleep (S3) for 1-3 minutes, then reboot, and try to flash back BIOSregnew.bin again, if you still get error 28, then flash programmer or pinmod is your only option

OK so i tried the abouve thing during the varsm command cmd spit out the things in the first attachment.
and after that when i dump new biosreg it is done properly , and when flashing it some error occurs.(screenshot attached)
also i just put my laptop in sleep mode normally (because i found on net that laptop only supports Sleep S3, if i did it wrong please tel me cause i dont know what is Sleep S3) , btw i got the same error after the sleep method too.

also please explain me about the both the methods after opening up the laptop, does pinmod method require to purchase anything new.
P.S also please tell if there is any other method you can remember which does not require opening the laptop...please :)
