KeeYees SOP8 SOIC8 Test Clip for EEPROM 25CXX / 24CXX with CH341A 24 25 Series EEPROM Flash Bios USB Programmer

I'm new to BIOS programming, but after understanding it's quirks, this is quite a powerful tool! My chip was from an HP ProBook 640 G3 and is held in place with a spring retainer mechanism; therefore, programming is done out of circuit. The spring clip of this device _must_ make solid contact, even at the risk of crumpling the pins. Just flatten them out later like I did. If using IMSProg like me, the telltale sign of a bad connection is that erasing only takes a few seconds. With a solid connection, it should take closer to a minute. The programmer works well and is a very inexpensive alternative to raspberry pi and whatnot. If you have a locked BIOS and need to get by the forgotten/unknown password, this is your oyster.

I bricked my asus b150m when I updated the bios. No screen display but fan and lights are on. I tried to diagnose, remove, reinstall ram/gpu/fans/etc - still wouldn't post. I watched a dozen of youtube videos but ultimately I know its the motherboard. This was my first action before moving to replace the motherboard which is expensive. It worked for me. Got my motherboard working and was able to install the latest bios. Company's link will let you download the necessary app to get this working. I'm not expert but I built my computer and fix it by myself :D anyone can do this. The pins took me only few tries to get it connected to the application. I might make a youtube video to help some folks out! If your mobo is still in warranty, RMI it. But if its gonna cost you to send your mobo to the manufacturer and months of getting it returned to you, this may be a route to go. Highly recommended to those who's mobo is out of warranty like mine, it wouldn't hurt to try this first before buying an expensive mobo but if it's a reason to upgrade then do so :P

It's a very cheap flash programmer, but it actually works very well. I've tried to read BIOS of a video card and firmware of a blu-ray player and easily succeeded both times. It's easy to use and it does what it's supposed to do. You'll probably need to spend some time to find proper software that works with this programmer, but at this price point it's not a big deal. I've read that you need to modify the programmer in some way so it uses correct voltage - it wasn't the case in my experience, I could just use it out of the box and it worked 100%. It's awesome that you don't need to unsolder anything, just connect the clip to the chip, connect the programmer to USB port of your computer and you're ready to work with the chip.

Love this little tool. Wish I had more excuses to use it. A friend locked themselves out of their laptop by setting a BIOS password that they couldn't remember. I cleared the CMOS memory several times, but the password persisted. I did some research and learned that modern laptops don't store BIOS passwords in CMOS. Instead, they are stored in non-volatile memory, such as the eeprom on the BIOS chip itself. Further research indicated that this particular laptop likely used an AMI BIOS implementation, and that the password could likely be decrypted or cleared. I happened to have this tool on hand and was itching for a reason to use it. I had never used a BIOS programmer before, so I read a few guides, identified the BIOS chip, and downloaded and reviewed its datasheet. I booted Ubuntu on another laptop and installed flashrom. I verified that flashrom was compatible with the BIOS chip. I hooked up the clip, and flashrom recognized the chip on the first attempt. I dumped the ROM three times and confirmed the checksums for each dump matched. I used UEFITool and confirmed that I was looking at an AMI BIOS and that the AMITSESetup variable was present. I found a tool on GitHub named AMITSESetup Decryptor & Unlocker that was unable to decrypt the password, but it did clear the password from the ROM dump. I flashed the modified ROM back to the BIOS chip, and much to my surprise I was able to boot the computer with no issues and no BIOS password prompt!

I purchased this to backup and restore a G2 Mini PC BIOS. Upon some YouTube research, I discovered that one of the other reviewers on here was correct, there is a design flaw with this unit using too much power on the data bus even though the power jumper has been changed for low power chips. I modified the board as described in the videos so that I would not damage my chip, and was able to make backup copies of the BIOS before flashing a different version to it. Unfortunately I found that the BIOS chip had to be completely removed from the circuit in order to flash the replacement version. It absolutely refused to write successfully while in circuit. Reading was not a problem. Chip that I flashed was a MX25R6435F which is not listed in the software. I used the closest chip number I could find spec wise. Also note: Make sure you clean all the pins on the chip and the pinch clip with alcohol before connecting. Any debris will cause errors, including flux.
