Because so many have been writing and commenting on My Blue Yeti Microphone Repair Video , I’ve taken the time to make this page to give you a little more detailed instructions when it comes to repairing this microphone.
Before starting to give them instructions on how or by whom malfunctions happen regardless of the brand of microphone.
Most USB microphones of different brands use a CM6400X chip from the CMedia. In the best cases, the microphone has some audio settings or presets depending on its structure. This chip is very susceptible to voltages and it can happen that if plugs into a usb 3.0 or 3.1 port its EEPROM can be erased . Because its memory is erased, the hardware is detected as generic with the name USB ADVANCED AUDIO DEVICE .
This has many consequences, low audio quality , saturated sound , software does not detect it , etc.
Most manufacturers do not support restoring the firmware to its default settings, which is why this idea arises to repair them by extracting the firmware directly from its EEPROM , or failing that, try settings until it works correctly or better than before.
As i’m indicated, many manufacturers do not offer a true solution to this, rather what they offer is an RMA guarantee , which is basically a replacement of the affected unit, but this is only applicable during the guarantee period and once the guarantee is lost. you can no longer get a replacement and the only solution left was to buy another one and the expense that this entails.Capture of the Blue-Logitech support where they indicate that there is no solution for this problem.

1. Download the zipped This contains the
screenshots with the values in the video, as well as the EEPROM Editor/flash (Config6400.exe).
V2 Add BACKUP_FIRM.bin
2. Open Device Manager, go to Sound Devices and right click USB Advanced Audio Device (Microphone) and go to properties.
3. Go to Details, Select ‘Parent‘ or ‘Last Known Parent‘ in dropdown.
4. Take the VID and PID Values displayed and put them into Config6400 Program at the bottom.
Example : Vid: 8D8C Pid:016C
5. Click Connect. Once successful, we are going to back up the configuration and grab a value from it. Simply click `EEPROM -> File` button at the bottom and save the .bin file.
6. Select a name and location to save your backup.
*If everything has worked correctly you should see the following message
7. Last step. Simply click `File->EEPROM` button at the bottom, search and select the BACKUP FROM.bin file zipped. wait for a message to appear asking for un-plug and re-plug to save the changes.
7. Download a Hex editor (I used HxD) to open and read the .bin file. You will want to copy and save the string immediately following the decoded text “Blue Microphones.Yeti Stereo Microphone”. If you don’t know what I’m talking about, see 12:48 of video 8. Fill in the Serial String you just grabbed, and the remaining fields with the same settings in the video/screenshots. Do the same for Volume config. EQ and Misc are unchanged. Once you’ve finished all this configuration, click Save EEPROM at the bottom left, wait for a confirmation, then unplug and replug your usb from your device.
Errores y SolucionesRecommendation: Connect the microphone to a USB 2.0 port or try a different one
You may also get a message EEPROM IS EMPTY !!!
Empty EEPROM ?
This is normal as your EEPROM does not contain information and the purpose of this guide is to write this information on the microphone chip and works correctly again.
