BIOS DUMP
ADMIN TOOL RESULTS

@rtncyp - I assume you have flash programmer? If not, let me know and I will tell you how to disable locks so we can use FPT instead.
Here is your unlocked BIOS - http://s000.tinyupload.com/index.php?fil...516314317127994

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

Wow you must be the King! What is this speed?
Thank you so much. Yes i do have ch341a programmer with clip i am at your service can you teach me this FPT and other things?

Thanks again and again
-------------------

Sorry i got excited 🤣🤣🤣

As i have the programmer dont need the FPT isnt it?
Also if i get tits up can i use my first dump to save the day?

Thanks master

@rtncyp - You're welcome! Yes, your thread caught me right while I was looking at a similar BIOS for another user, so I knew I could do yours real quick while I was on the other

FPT method not needed since you have programmer. And if you wanted to try it for later, there is several guided steps I'd have to walk you through, a few methods/things you need to do, and then maybe it will work (not sure on this model yet, no one tried, but I do assume maybe possible)

Yes, you can always use your original dump to recover, provided you can write to chip properly (already know what software/version writes to your chip OK)

If you want to know FPT method, and try going that route without using programmer, we can, but you will use different file and I will have to do edit again (Not a big deal, just letting you know current file will not be used)
If you want to do that instead of using programmer, let me know. And then do below. We already know step #2 result = 167, so just do #1 AFTER you do the vars stuff and send it to me, then program back the unlocked vars, then you will do #1 and send to me

@rtncyp - Where did you go?

I have the same notebook, and want to mod too @Lost_N_BIOS Can you help me?

Ok friend, your bios is locked (Eeprom) you got error 167 so Bios lock and FPRR ...

We have two ways

1. H2OUVE tool
2. RU Shell


Download these tools (try one for one and look if there are errors) :

https://www.mediafire.com/file/51rqk94x9...H2OUVE.rar/file

So use the H20UVE_100.00.16.08 version tool to make a vars.txt backup and upload it for me, from a Admin command window run this command :

H2OUVE.exe -gv vars.txt

Upload it for me as i have to edit it and ulpoad to you ...

Then use RU Shell to modify that variable (from EFI IFR txt) :

0xBFC59 Suppress If: {0A 82}
0xBFC5B Variable 0x7E equals value in list (0x1) {14 08 7E 00 01 00 01 00}
0xBFC63 Setting: BIOS Lock, Variable: 0x17 {05 91 CD 06 CE 06 12 0A 05 00 17 00 10 10 00 01 00}
0xBFC74 Option: Disabled, Value: 0x0 {09 07 04 00 00 00 00}
0xBFC7B Option: Enabled, Value: 0x1 {09 07 03 00 30 00 01}
0xBFC82 End of Options {29 02}
0xBFC84 End If {29 02}


0xB372B Setting: Flash Protection Range Registers (FPRR), Variable: 0x6D1 {05 91 7A 0D 7B 0D 0F 05 05 00 D1 06 10 10 00 01 00}
0xB373C Option: Disabled, Value: 0x0 {09 07 04 00 00 00 00}
0xB3743 Option: Enabled, Value: 0x1 {09 07 03 00 30 00 01}
0xB374A End of Options {29 02}
BIOS Lock, Variable: 0x4AB 0x01 >> 0x00

This one locks the eeprom.

Here the RU Shell and a guide on how to :

https://nstarke.github.io/0037-modifying...ing-ru-efi.html

https://www.instructables.com/Lenovo-Y70...Me-Gen3-Speeds/

You have to find the PCH-Setup GUID: 4570B7F1-ADE8-4943-8DC3-406472842384 , then modify the variable 0x17 from 0x1 >> 0x00 ans variable 0x6D1 form 0x01 >> 0x00
Then reboot to windows and use Fptw64.exe to make a bios backup , upload it for me and i will clean it to make a bios mod.

Please when you find it upload a photo so i can be sure and you too that you're patching the right one ...

Regards

hi, i will do this next tuesday, i send you photos, tank you!

link from mediafire not working!! i downloaded H2OUVE from another link

H2OUVE vars.txt here

https://mega.nz/file/SD50yALD#EghO6-IjpY...OyIAxBd8biD4MA0

Ok friend,
to use the tools you have to open a command window as Admin, go into the folder's tool and use shift and right mouse click and choice
Open Powershell window as Administrator , to open command window, then run cmd + ENTER and go ...

use H2OUVE like before to rewrite back the varsmod.txt (varibles modified), put the file into the folder containing H2OUVE.exe and execute this command :

H2OUVE.exe -sv varsmod.txt

Here is the file :

https://www.mediafire.com/file/4uieawkit...FL_Mod.rar/file

Then use this Fpt tool to flash the biios mod , from the FPT folder execute this command :

fptw.exe -f biosregmod.bin -bios

Here is the Fpt tool :
