Another error:

 

Now when i am trying to make backup of my BIOS:

 

(on simple double click):

Quote

Error 284: Fail to load driver (PCI access for Windows).

Tool needs to run with an administrator priviledge account.

(Run as administrator)

Quote

Error 75: "fparts.txt" file not found

But as your may guess - it's in the same folder.

I am also added in *.bat file full address. Now it's look's like so:

Quote

C:\Folder\FPTw64\fptw64.exe -d BackupBiosY500.bin -bios
pause

 

SOLVED:

 

Right click on fptw64.exe and go to Properties => General Tab (press Unlock button)

Then go to Compatibility Tab and check box Run as Administrator

After that your are able to just double click on backup.bat

Lol, i am KEEP getting Errors!

 

New one is - i can't Drag-and-Drop modified BIOS in svl7 tool. =) It's showing me circle with "/" line.

I was smart and check box Run as Administrator in Compatibility Tab of BiosFixer_2.0.exe before running the tool.

 

So, now need go back and uncheck the box. :)

Hi guys

 

I am planning to install the modded bios soon. so, have a few questions.

1.I am running windows from an MSATA drive. Will this cause any problem when I install the modded bios?

2. is it possible to go back to stock Bios if there is some problem later?

3. which is the best wifi card in your opinion? 

cheers,

MJ

1. No

2. Yes

3. Intel AC 7260, but be sure to use WLAN Optimizer (http://www.martin-majowski.de/) with both 'disable background scan' and 'enable streaming mode' checked to prevent ping spikes caused by Intel's POS drivers.

its totally safe to use the mod, if my bios version is already  2.04. right?
@octiceps Thanks for the fast reply :)

 

Yeah it's fine. I flashed from stock 2.04 and have been running this for over 3 years now.

I am so frustrated with Lenovo ... is there a listing of all the companies that do this?  I'm starting to look for a new laptop and don't want to find myself limited by this stupid corporate moneymaking scheme.

My information could be outdated but as far as I know, MSI, Acer, and Asus don't have the whitelist bs.

Lenovo, HP, Dell, and Toshiba who are still doing it.

I'm looking at the changelog between v3.05 and V3.08 and the only thing I can find is:

 

Quote

Summary of changes
==================
General Information:

74CN47WW 
1. Implement code for uEFI security vulnerabilities. 

 

Is it worth to mod the v3.08 or just go with v3.05?

      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 ?
