@kalekulan I had the same. When I upgraded emmc can't boot anymore. It doesn't get detected when plugged to usb by itself. SD card still works tho you can try to force boot it. Put the jumper on the mask rom mode, and place a bootable sdcard, then plugged it to USB. It might help if you can monitor the serial port. The sdcard will boot but it will detect the eMMC mode and the eMMC will be detected by the pc. Then you can do the usual dd'ing. EDIT: with the eMMC booting now, it still don't get detected by the pc when you plug it in, but atleast it boot now. And somehow it just shutdown on me just now, over temperature. only got mariadb and freeradius running on it. My tiny rpi copper heatsink is most likely no enough.

Yeah, it's the S version that I have. Wha'ts puzzling about it is, the same image file loaded to the sdcard works. Edit: It's working now again, I dd'd the image this time. last time I used balena etcher. There must be something different with how it write image file. Thanks for the continuous support of this aging board.

I have the same problem, I had it working for a year. Yesterday I decided to upgrade and I thought I burned the board. Luckily the SD-card still works. @Scott Picton I tried your fix didn't work for me. I forced boot the board with the sdcard in it but with the jumper on for eMMC. and tried to dd the .spl, but nothing changed. did you dd the .spl from the same image of the latest released? or from an older release?
