Dead PinePhone 64 - does not power on at all

[publiclewdness]

I have used my PinePhone Pine64 Manjaro Community Edition for four days. I was having an awesome time with it, trying out different distros and UIs. Everything worked beautifully at first and I'm well impressed with the current status of usability of the phone.

Now, the phone is dead - absolutely dead: no LED action, no screen (not even backlight), nothing happens anymore.

How it started:
The problem started when I had the phone running Mobian+Phosh.

I had it docked on USB keyboard/mouse, HDMI and power (although the battery did not really seem to charge, it was losing charge %).
I had updated some packages and installed some new ones.
In the terminal I gave the command: sudo reboot.
At this point the charge on the battery was probably down to a single digit (5% maybe?)
I left it in the dock.

The phone started to reboot and even power on again. On the external monitor, a very hazy version of the Mobian logo appeared (so it started to boot).

Then all went black and the phone has been dead since.

Current situation
Nothing works.
I tried the reset pin, multiple times for over 15 seconds. Removed and replaced the battery a couple of times. Held the power button multiple times for over 10/15secs.

There is no indication that anything at all is still going on in the phone.

I left the phone charging overnight (the whole night), and still no luck this morning.

The only thing that is still happening is that the phone draws power (when I connect it, I can hear coil whine starting on my cheap charging station, and when I connect it to my power bank it shows dots indicating something is sucking power from it - both charging methods were used without any issues during the first four days).


I am at a complete loss as to what's going on and I don't know what to do next... it would be a real shame if this was it and the device is now dead.

I hope anyone can help. If you have any suggestions as to what I could try or do next, please let me know!

Cheers.

First off thank you for helping me. I had a similar issue as you with my Pinephone CE. I had been running Mobian Phosh on the EMMC and after doing a round of updates it wouldn't turn on after. I tried plugging it into different ports and wall outlets; discharging the battery; different cable; different battery but I just tried an SD card with Jumpdrive like you suggested and it is booting from that so I am going to first try reinstalling Mobian but if that continues to give me issues I will try another distro. I think there was some update causing the issue in Mobian but I can't be certain what. I didn't use the dock at all recently so I don't think that had anything to do with my problem.
