Odyssey J4125v2 dead after BIOS update

Success! I was able to get access to the BIOS and the device is working perfectly as a happy little pfSense router now :slight_smile:

I used GitHub - nofeletru/UsbAsp-flash: Program allow you to program flash memory on the protocols spi, I2C, MicroWire. Supports CH341a, CH347, UsbAsp, AVRISP(LUFA), Arduino, FT232H. along with the previously mentioned USB programmer. I had to purchase an extra socket that would fit the chip (I opted for the larger of these two Amazon.com)

I connected the 1.8V converter to the programmer USB, then the 200mm socket to the 1.8V converter, booted up AsProgrammer, and followed the steps here (AsProgrammer and other Windows utilities for CH341A · One Transistor) to scan for the winbond chip. I made sure to save a copy of the scanned firmware, just in case, and then on the dropdown next to “Write IC” I selected the “Unprotect → Erase → Program → Verify” option. This worked after a few minutes without any issues!

Anyone can feel free to reach out to me if they need assistance with this in the future, but I hope this breakdown helps! I had to do a lot of digging myself, so hopefully this saves someone some time and headache.

Hi. I have a similar problem (Odyssey J415-V2 blocked). I wanted to ask where I can currently download the bin file for flashing the BIOS? The product wiki page still only lists the version for J4105/J4125-V1. Thanks.

Hello. Same problem (BIOS is locked with a password in Odyssey J415-V2). Could you help me with getting the firmware file?

Hello. Thanks for the answer, but to which email address should I send the question? I sent it to [email protected], they replied that it was possible and suggested looking for information on the target forums. And that’s it, nothing more.

Hi adam, please kindly refer to the wiki. We do not provide the BIOS for the V2 version, and this product has already reached EOL (End of Life) and will no longer be maintained.
