BOOT ERROR: Failure to read device ID - drh - 01-10-2025
Hello,
I have a Pinephone Pro device. It is one of the early models with the microSIM slot.
Note: If I do not have a hardware problem, I will repost this thread in one of the other PPP form categories.
The device has tow-boot installed with Mobian (Bookworm) for the operating system, which worked quite well for me (only problems were poor battery life and inability to switch between external speaker and phone speaker without a reboot).
Mobian is installed on the internal eMMC storage. The microSD for extra storage is empty (not used).
The battery drained fully and upon recharge the PPP booted to this error message.

The "pinephone-keyboard 5-0015: Failed to read device ID: -6" error is mentioned in this forum thread titled The Case of the Vanishing EMMC; however, I do not have the knowledge to confirm from the thread that the root cause is an inoperable hardware.
The pinephone-keyboard 5-0015: Failed to read device ID: -6" error is also mentioned at this git-hub thread two-boot installed on PPP/ EE. USB mode works, but can't boot from SD; however, I cannot decifer the fix.
I followed the directions to revive a PPP with a fully drained battery described at Troubleshooting; however, this did not restore the ability to boot.
I did a reinstall of Mobian to the eMMC storage and on boot up, the same boot error message appears...

Is there sufficient information above to diagnose the root cause is hardware related?
Is the root cause a busted eMMC device, pinephone-keyboard, or something else?
If the root cause is hardware, what is the replacement?
Any help and advice is greatly appreciated.
