  1. Some guide how to use SPI Programmer CH341a:Step 1.If you already get your modified bios then go to Step 2.Step 2.Purchase the necessary equipment.To flash bios mod in to your bios chip you need a CH341A programmer and a SOIC8 SOP8 test clip. (You can found them on ebay, it cost a total of $20 USD for both items.)Step 3.The drivers and software for the hardware you can purchased were located on the seller's ad page on ebay.) This step should usually be completed BEFORE plugging the programmer to your computer. Installing them before plugging the programmer into your computer will help avoid potential driver trouble with Windows. (If you have some trouble with drivers installing, then just disable "Driver Signature Enforcement" as the drivers were not digitally signed). After installation, reboot your computer.Step 4.Connect the clip to the programmer and then plug in the programmer into your computer. Run the included software.Step 5.Now you should try to search the bios chip on your motherboard. Usually you need 8-pin chip with first two digits 25, like this: Winbond 25Q32FVSVQ, 25Q32FV, 25Q64FV, 25L3273E, MX25L6473E or the same.Step 6.This step will be based entirely on the software that came with your programmer. Enter in the exact chip information or, if the software you're using has an auto-detect option, you can use this, but I would recommend double checking.Step 7.Read the chip. Read the current programming on the chip and then read chip again. Then make some comparisons between them with any Hex editor. Make sure that it looks exactly the same. Remember, they should be the exactly identical, so they should still look exactly identical.Step 8.Load the modified bios file and write it to the chip.After loading the modified file, the tools use only required click an "Auto" button. This then took around a minute or two to write everything to the bios chip. If the program freezes, or appears to be doing nothing, don't touch anything for the next 10 minutes as you don't want to mess anything up if it is doing something.Step 9.Done. Remove the clips and see if your laptop boots. Another guide: Open your laptop and find your bios chip and search for it. Usually you need 8-pin chip with first two digits 25, like this: Winbond 25Q32FVSVQ, 25Q32FV, 25Q64FV, 25L3273E, MX25L6473E or the same Connect the ch341a and clip to your windows machine and laptop Open ch341a programmer 1.13/ CH341A.exe click “chip search” if it find your chip then next step, else rechip the chip/ Open ch341a programmer 1.26/ CH341AFree.exe choose your bios type/size. Click Read After done click Save (original_1.bin) Repeat step5 and save as original_2.bin Open HxD “Crtl+k” compare original_1.bin and original_2.bin if they are same go to next step otherwise repeat 5) Then post it in the relevant topic or upload it to any fileserver and post the link in the relevant topic. When you get your modified bios, then time to write bios to the chip Open ch341a programmer 1.26/ CH341AFree.exe choose your bios type/size Click Erase it will erase your chip . You must do it before flash After bios chip will be erased , then click Open, choice your modified bios Click Write and wait 100% Now the mod is done, remove the clip and power on the laptop, it will beep 5 x2 time , it will gone once you go to bios setting and restart.

    Some guide how to use SPI Programmer CH341a

    No. It's will possible only when hardware SPI-Programmer will connect to bios chip. Yes.
  4. Hi! This thread for another laptop model. You can create new thread for your laptop.
  5. Hi! Each bios mod prepared individually and based on your personal bios dump (which you must read from your bios chip with hardware SPI programmer). Just read first post of this thread.
  6. Hi! Yes, to unlock your bios, send me your file bios backup from your laptop. For creating backup of bios use attached utility. Extract attached archive directly on the Desktop and run the backup tool as Administrator (right click mouse). Utility will create archive "results" directly on the Desktop. Send me this archive "results" via PM or or upload it to any fileserver and post the link. https://www.sendspace.com/file/mxoavw or http://www120.zippyshare.com/v/NC9WuxRI/file.html

    mod bios

    This laptop model have special TPM/Security chip, every time when laptop start, this chip will check special RSA signature. When the BIOS integrity test fails, a sequence of 5 whistles is issued twice at boot. After modifying to remove whitelist (enable unauthorized WI-FI cards), enable advanced menu, etc. the BIOS can't pass the integrity test (because bios was modified), and therefore sequence of 5 whistles is issued twice at boot. In this case, I know only this ways (sometime it's can help, but sometime no) : Pull out CMOS battery and wait 5-10 min to reset NVRAM data. Set (in bios setup menu) TPM to Inactive (not to Disabled) after flashing. Set (in bios setup menu) Security chip to Disabled. Set Intel AMT module (in bios setup menu) to Disabled. Set Anti Theft Module to Disabled. Set Computrace (in bios setup menu) to Permanent disabled.
  8. Hi! This thread for request to unlock bios for Lenovo G580 (20150) and (2189) model only. Not for model 2689. But you can create new topic for your laptop model.

    Hi! Ok. Check PM.
  11. If someone wants upgrade Wi-Fi card and remove witelist, or unlock hidden additional menus and settings, or unlocked vbios for overclock NVIDIA card, then you can post your request in this thread. It's for Lenovo Z710, Z510 only!
  12. In this thread you can post your requests for Lenovo G500 and G400 bios unlock. 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. For prepare unlocked bios you should post your request here and then send me your file backup of bios via PM. For creating backup of bios use attached program. Extract attached archive directly on the Desktop and run the program as administrator (right click mouse). Program will create archive "results" directly on the Desktop.
