WWZMDiB CH341A Programmer & Removable SOP8 Test Clips Organizer SOIC8 SOP8 Flash Chip IC Test Clips Socket CH341A 24 25 Series EEPROM Flash BIOS USB Programmer Module

bought this CH341A programmer kit to recover/reflash the bios on an MSI laptop that I picked up as a repair project.The laptop still powered on, but the bios setup was locked, so I wanted to make a verified dump of the SPI flash and reprogram it with the correct official bios image.My chip was a Macronix MX25L12873F, which 1 did not see specifically listed on the included 25-series support chart, but the programmer still worked correctly with it. The chip was detected through flashrom under the compatible Macronix profile, and I was able to read the full 16mb bios image, make multiple matching dumps, write the replacement image, and verify it successfully.The SOIC& clip also worked well enough once I had it aligned correctly. As with all bios/SPI work, the connection has to be solid. I had the laptop fully disconnected from AC power, main battery, and CMOS battery before attaching the clip.After reading the chip multiple times and confirming matching hashes, I flashed the official MSI bios image and the laptop booted successfully afterward with access restoredA few notes for anyone buying this for bios repair:Make sure your chip voltage is correct before connecting anything. My chip was a 3.3 V SPI flash chip, not 1.8 V. Also, do not skip the backup step (trust me). Read the chip more than once and verify that the dumps match before writing anything. The included adapter/clip is useful, but the process still requires care, patience, and the right software.Overall, this kit did exactly what I needed. It worked on my MX25L12873F even though that exact chip was not listed and it saved this laptop from becoming an expensive paperweight. Good value for anyone doing bios recovery, EEPROM/SPI flashing, or board-level tinkering/repair work.

Tenía 2 laptops con problema de bios una Dell y una Hp. Con el pude reprogramar fácilmente y sin problema, no tuve que desoldar la bios ni nada. El programa lo encuentran en línea y los archivos hay un canal en telegram que tiene de todas las marcas.

Muy buen producto, me sirvió para la recuperación del bios

It way or may not work; In my case I had to desolder the 25L4005A chip off the motherboard so I could flash it. Something on the board was drawing down the programming voltage so the chip would not program. It could read the chip and erase it but would not program. There is some Chinese CH341A software out there, look for Neoprogrammer CH341A instead as it works better and has a little better interface. Once everything is working, flashing is trivial, good tool to have in your toolbox. Install the driver first, I did flashing using a Win10 laptop.

Godsend! Worked for my purposes and the price was right as well. Used this (and other tools) for accessing the 4 digit PIN code on a 2005 Chrysler Town and Country that I needed to program new keys for.
