  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. Another guide: Also, you can search on YouTube a lot of guide for CH341a. CH341A programmer: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2322090.m570.l1313&_nkw=USB+Programmer+Ch341&_sacat=0 https://www.amazon.com/s?k=ch341a&ref=nb_sb_noss_2 SOIC8/SOP8 test clip: https://www.ebay.com/itm/Soic8-Sop8-Flash-Chip-Ic-Test-Clips-Socket-Adpter-Bios-24-25-93-Programmer/201414947737?hash=item2ee5443399:g:up8AAOSw1Fda8qkt https://www.amazon.ca/programming-EEPROM-Programmer-EZP2010-RT809H/dp/B075CGH1X1/ref=sr_1_18?dchild=1&keywords=SOIC8+clip&qid=1631766855&s=electronics&sr=1-18
  2. 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 !!!
