I have had few Switches with presumably dead eMMCs. These switches were never opened before
One switch runs Ubuntu fine but Hekate or other payloads cannot access the eMMC and I can’t backup the eMMC even with HAC-EMMC external reader.
One switch (maybe patched) accepts payloads via TegraRCM but nothing on the screen (tested with another screen). How do I know if the switch is patched? Based on the serial number it is but no error when I inject the payload. I tried this eMMC on another one, but I get the same “init eMMC failed”. Also the external reader does not recognise the eMMC. This switch has had impact damage because I replaced the screen few months ago so maybe the eMMC is recoverable with reflowing?
There are no backups of these NANDs so I guess these switches are non-repairable. Have you had many of these dead eMMC cases and were you able to recover any?
