Recommended Posts

Hello everyone. I am a rookie member. I got a Lenovo Y580 which I want to flash it with the modified BIOS 5DCN90ww (V8.01) and I did flash it with the command fpt -f v801.rom  -bios and it went till the end with no errors but at the end shows that the 2 bioses are exactly the same. What Can I do to get a ready modified bios, I mean the real thing, unlocked, white list removal, advanced subMenues and gtx660M accelerated. I got a wirelessland 7260HNM DUAL BAND, 4.0 BT and 2x2 867Mbps which is awating the transformation of my Y580.  I 'll be willing to a down payment as a donation if that is ok with you. Final note on the 2 bioses, I compared them with the DOS command FC and there were many diffencies... I'll leave it to the experts, Gracias amigos!!!

Hi!

Send me your file backup of bios.  For creating backup of bios use attached program. Unzip attached archive directly on the Desktop and run the utility as Administrator (right click mouse). Utility will create archive "results" directly on the Desktop. You can send me this archive "results" via PM or upload it to any fileserver and send me the link.

image.thumb.png.0c56e143310065d0bc62169e10e2b736.pngI had tested this in gaming for an hour and if it passes here in Venezuela and even in Guatire that the ambient temperature is around 30 degrees Celsius and my 660M gets into the mid 70s, i.e. 75-78 C. it is ok, taking into account that there is a lot of headroon to cpu Tj=105 C, which is the cutoff temperature.  Anything else that you can provide to the mixt in order to inprove it is a bonus and is well received. Thank you for everything and we'll keep in touch... I image.thumb.png.0c56e143310065d0bc62169e10e2b736.pnghope this single screenshot be suffient if not please let me know.

On your screenshots I see that unlocked bios already flashed and installed correctly.

Just reinstall Nvidia drivers with enabled option "Clean Install".

Thanks I'll try it out!

Has anyone been able to succesfully flash bios v8.01 yet??

Well, I did flash it but not successfully. I think there is some regions or blocks in the chips that are write protected. my flashing procedure is the same as everybody else.  Klem, I am afraid that I got no unlocked bios, no advanced submenues, no white list removed ( An unauthorized wireless network adaptor is plugged in, please turn off and remove) and some mixt results when it comes to the gtx accelaration. Pls somebody help me.

I will love to cooperate with any of you

Hello all, I'm glad that I found that topic after so many years. Unfortunately I bricked my Lenovo and I was looking for my old modified bios.
Sad that I'm no longer promoted to download any files...
Once I got promoted I'll test what @svl7 coocked for us.

 

Thank you for including what the readme says, the zip file above is no longer available. It helped me a lot with unbricking my pc!

In the zip file from the link that Makinachan just posted, there is a folder called "Crisis," and inside of that folder is a readme and a bin file called "QIWY3.bin". Here is what the readme says:

@Klem, i have similar problem like Berpeca. I tryied to flash v801 mod but nothing changed. Could you send the mod as well to me?
If you want, I can pay for this. After flash nothing changes. I don't have idea what is wrong... Still 950 MHZ on default clock. If you could, please reply to me on PM or here. Thank you in advance.

Hey all, appreciate all of the info in this thread. I'm stuck on one issue and would appreciate any help.

 

I am trying to recover a bricked y580. It has two BIOS chips: EN25Q32B (4MB) and EN25QH16 (2MB). I am using a CH341A serial programmer.

 

How do I properly pad or edit the .bin BIOS file and split it between the two chips?

 

Edit: Success! There is hope if you brick a y580 with the v8.01 BIOS! It does require disassembly of the laptop so you can access the BIOS chips with a CH341a serial programmer. I used the SOP8 SOIC8 test clip with it to avoid any soldering.

 

After trying dozens of BIOS files, the ones that worked were from a polish forum. It is an actual non-modded version of the QIWY4 BIOS. The file, la-8002p.zip, contains the .bins needed for the BIOS chip and the EC chip.

Thank you very much. How do you change the .rom file to .bin? Just change the file extension? By steps on page 1 in windows 10, I can't do anything :( Where to get the Flash.bat file?

Danieleczek, the filename can be anything you like.  The way to flash it is by booting into dos and flashing it using command line tools.

 

1 - get a spare USB stick

2 - in windows download yumi https://www.pendrivelinux.com/downloads/YUMI/YUMI-2.0.6.9.exe

3 - run the exe, choose your usb stick (don't get it wrong), and opt to format it, and install balder (which is freedos).

4 - The flash drive will be labelled MULTIBOOT.

5 - download prr.exe and fpt.exe (attached to this message) and copy them to the root of your MULTIBOOT drive

get em here:

6 - copy the rom I posted to the same place, and rename it to v810mod.bin

7 - restart your machine and elect to boot off your usb stick in NON-UEFI mode (ie you need legacy mode) - you might need to change your bios settings to do this, or try pressing F12 as your machine comes back up and choose your USB stick.

8 - select  balder and press enter - you should see an A: prompt

9  - type c: (and press enter)

10 type dir

11 you should now see the files on your USB's MULTIBOOT drive

12 type prr (enter)

13 type fpt -f v810mod.bin -bios (enter)

14 you should see your bios roms chips being written to and verified

15 reboot and press F2 to see your new unlocked bios (NB ethernet is disabled by default, so you will need to reenable)

Hope this helps my problem. And then I bought a card, but I can’t insert it, it immediately blocks it. I tried to install the older BIOS, I copied it myself under my card, to flash it, so it knocks out an error. And this version is only on some sites, and then there are basically only dumps for the programmer, and since I do not have it yet, I have to torment and search.

Hi folks, would anyone happen to have a v2.07 1.20v bios? I know it's an old topic, but I'll take the chance :)

 

I was able to get my gpu to 1340mHz on 1.150v, 1.175 doesn't make a diff, I would like to try getting 1400mHz on clock. So far temperatures don't go over 66c.

      Hello, I just got my exp gdc dock (Beast) and my GPU (ASUS GTX 1660 SUPER) and it seems like the bios "blocking" the egpu.
      Can someone give me a mod?
      Thanks

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!

      In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating bios backup and to flash bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.

      To install the unlocked bios, I prepared and booted a freedos usb. I start the installation by typing flash.bat but every time I get the following error: Error 28: Protected Range Registers are currently set by BIOS, preventing flash Access. Please contact the target System BIOS vendor for an option to disable Protected Range Registers.
      How can i solve this problem ?
