BOOT ERROR: Failure to read device ID

[drh]

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...

I did a reinstall of Mobian to an sdcard and on boot up, the boot error message is...

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.

Update: I figured out that the issue I describe above was due to installing the Weekly build of Mobian (phosh) on the eMMC. The Weekly build of Mobian (phosh) boots up properly when installed on a sd card. I successfully installed Mobian 12 (bookworm) on the eMMC, but could not figure out how to upgrade to trixie. I could not find instructions how to upgrade that worked. I could not get past repository not signed error message after modifying the two sources files. I did not want to stick with Mobian 12 (bookworm) because the audio issues are annoying and it is uncertain whether I would be able to upgrade to trixie. I might do a fresh install if Mobian is released with a fully working installer to the eMMC.

Note: I do have to say that the PPP with towboot is pretty slick. Installing a new OS and booting from an sd card are quite easy and very handy.

I ended up installing PostmarketOS (phosh) stable on my pinephonepro, which is working (audio calls) so far.
