Hey everyone,
I’m hoping someone here can help. I accidentally flashed the E30 II Lite firmware onto my regular E30 II using the Topping DFU tool. Now the DAC powers on (shows PCM when using optical), but it’s completely unresponsive over USB — not recognized on my PC, and the DFU tool shows “No device found.”
I’ve tried:
I know some people on this forum have recovered theirs in similar situations — has anyone dealt with this exact issue when the DFU tool doesn’t see the device?
Is there any way to flash the firmware directly using ISP/JTAG or anything else DIY before I consider shipping it out for repair?
Any suggestions would mean a lot - thanks in advance

I’ve tried:
- Multiple USB ports (rear I/O, different systems)
- Pressing the “headphone” button 5x in standby to enter DFU mode
- Using the correct E30 II_FW1.13.bin firmware file
- Reinstalling drivers
