WINGONEER® EEPROM Routing USB Programmer CH341A Writer LCD Flash for 25 SPI Series 24

Used this to successfully flash two different Winbond BIOS chips after first modifying the BIOSes with UBU to include the latest Intel CPU microcode. This meant I could update two expensive dual-Xeon motherboards that ASUS had abandoned to Spectre and Meltdown.The shipped product is hardware only with no software or instructions. If you're already running Linux or can install it on a spare PC (I used Ubuntu) then just install flashrom (search to find the download site, it's pretty obvious) and you're away. Use "sudo flashrom -p ch341a_spi" to access the USB programmer and confirm it can read your chip, then check the help for the actual flash programming commands. For programming, the jumper needs to be across pins 1+2 which is how it was sent to me.If you can't use Linux there are Windows and Mac drivers at the chip manufacturer's (WCH) Chinese language web site. There is also a blog called 'One Transistor' where the author did some research on this programmer and linked useful files from WCH's web site with English explanations of what they're for. The video mentioned in one of the other reviews is also helpful if somewhat long-winded.

I had a hard time getting software to work on Windows with this device. Plugged it into my Linux laptop and used flashrom instead. Works perfectly

Had to hack mine, the CH341 chip is supplied with 5v from USB. This makes the data lines output 5V when communicating with the chips you use with it. It has an onboard 3.3v, which supplies power to the chips you're working with though, so you just have to do a bypass and two wires which requires some micro soldering.

In conjunction with WINGONEER SOIC8 SOP8 Test Clip For EEPROM..., I recovered my $2,000 27" touchscreen i7 PC using this, after DELL and Microsoft Windows 10 managed to kill it, without claiming responsibity for it. I mean kill it - just black screen without any BIOS access. I have also recovered two ASUS touchscreen high spec laptops for my children after Windows 10 upgrade disasters.

Not that good, you might want to invest a bit more on better and more reliable tool

This EEPROM programmer worked perfectly and let me recover my car radio code after a battery fault!

The price is good but the item comes with zero information and I've spent a morning trying to find drivers and software that can use it, it may well work but the silk screen is in chinese so I've no idea what jumper settings are correct unless I trawl through youtube videos and hope that the ones which *look a bit like* this one are correct. I didn't expect this to be a simple/smooth out of the box (actually it was a bag) experience but I will probably wind up buying a more expensive unit so I can get even a minimal level of support.After a few hours and several failed attempts found a rambling but accurate video with a link to the software and drivers:https://www.youtube.com/watch?v=5NYe21nFSDI

Worked perfectly
