The Case of the Vanishing EMMC
04-17-2023, 04:34 PM
Booting into MASK ROM: There is no led but on a secondary computer it is recognised on the bus. "Bus 003 Device 006: ID 2207:330c Fuzhou Rockchip Electronics Company RK3399 in Mask ROM mode"
With Volume UP: It starts to go into Mass Storage Mode, the led goes blue and then the phone pulses for four and resets, sometimes just vibrating until it is unpowered.
With Volume DOWN: It starts to boot the O/S. pmOS (both image and installer) halt because no boot partition is found; Mobian gives me the quoted read out; Manjaro gives me more errors, similar to Mobian, clearly related to the emmc (mmc1.) However, with Manjaro the led goes to a yellowish white vibrates for a while and then gives me an emergency shell.
Using blkid while in the em-shell gives me I/O errors on /dev/mmcblk1, as does fsck on both mmcblk1 & mmcblk2.
I originally used gparted to clear the emmc while the phone was in mass storage mode. I was troubleshooting the sdcard and was querying whether it was because there was an O/S already on the device. I have tried alternative sdcards and the same issue (described above) occurs.
