I ended up here because while attempting the NVMe via Flashback the board seemed to crash and the board would no longer post. CH341A Programmer is a tool used for programming and reading data from various microcontrollers, EEPROMs, and other types of memory chips. For the people that had the same problem(s) here is a photo of how it should be connected propperly. The proposed mod is simply to make three track cuts disconnecting those pins from the Vcc trace on the bottom side running under the ZIF socket, to add a wire link to patch the interrupted Vcc track back together, leaving out the /HOLD pin, then to fit pullup resistors from the Vcc track to the /HOLD and /WP pins.

Specifications: Material: Electronic Material Options: CH341A Programmer / CH341A and SOP8 Clip (optional) Power: 5W Voltage: 5V Current: 1A Item Size: 9. It didn't have the pinheaders on the sides of the ZIF socket which I wanted to know what they are for. bin attached – initially I extracted this with flashrom but, now, I can’t recognize the BIOS chip using that. The lack of any voltage on MOSI and MISO leads me to belive the chip is broken internally, though it's strange that is still enumerates from the USB side.Compatible with various adapters like the handy Sop8 or sop16 tweezers with an alligator clamp to do the job without removing components from the board.

I dont have a previously saved good BIOS file, I backed up what was on the assumed corrupted bios chip using flashrom but when I read that in FD44 its blank. Once these are downloaded and installed, it’s time to connect your CH341A programmer to your computer via a USB cable. For 25 series chips (SPI), you can use the "Auto Detect" button to read the id / signature of the chip.Using SOP8 programming clip: This method is suitable for BIOS chips that are soldered onto the motherboard and cannot be removed.

I'm down to a bios issue and I stumbled upon the flashing process and have picked up the reader/programmer listed here and was able to get a read off the chip, however, when it comes to flashing the only file I have been able to find from Intel is '. Run the programm, now there are no 95xxx type of eeproms available in the software, select 25xxx, with same capacity as your chip.Finally, for those of you less experienced with SMD rework and board mods *PLEASE* for your and our sanity, and to reduce the risk of snapping the Vcc pin, get some 28 or 30 AWG Kynar wirewrap wire or magnet wire to do the mod with! programmer, in addition to the Vcc pin lift already discussed, you need to add a tiny DPDT switch with one pole switching Vcc between 3.

I will place the link for the 16 pin chip clip at the bottom of this blog along with a link for the CH341a programmer. Also the NVMe mod on this motherboard is straight trough…no fuss, if the mod you flash was not well made then its the cause of it.Therefore, I grabbed the datasheet for the MX25L6445E SPI chip and looked at the pin diagram and identified the type of package that is installed on the WNDR3700 circuit board. I tried to do what you said, I disconnected pin 28 and left only pin 9 powered, the device didn't turn on. Thankfully I was able to program the chip for my project using the other working one, but I'd be curious as to what's wrong with my black CH341A programmer, and will test it further in the coming weeks. For 24 series chips (I2C), you will have to select it manually as they don't have any id / signature for us to identify them. For improved reliability and to avoid burning memory chips, I highly recommend using a level shifter.
