Frozen screen, bricked Pure?

[sharethewisdom]

Hi, yesterday my Pure’s screen froze at 11PM. The device doesn’t show up when connecting via USB to a linux machine (no messages shown when running sudo dmesg -w.

I tried re-seating the battery, and then charged it with a 5V 2A charger from the Raspberry Pi foundation. The issue persists.

I had successfully updated the OS-P on Sat, 1 Oct via Mudita Center, and everything seemed functional.

Is there something else I can try?

@sharethewisdom Thanks for reaching out. We’re sorry that you’re experiencing issues. What happens if you plug the phone to your laptop? Is it recognized?

[sharethewisdom]

Hi thanks for your reply. No, it is not recognized.

@sharethewisdom

sudo dmesg -w

I plugged / unplugged the phone with usb while running the above command (that is commonly used to find out if the linux kernel ring buffer receives info about a new device). When I did the same thing a week ago, while the Pure was “alive”, messages appeared with vendor info.

To be sure - the phone is not responsible after reseating the battery and turning it on? Please leave it then connected to the charger for a longer period of time. If it won’t help, we’ll try to figure out what happened

try different cable

I’m relieved to report that I was able to turn on the phone and connect it after a two-day charge.

How do I inspect the MuditaOS logs? I think the battery was not depleted at the time it froze the screen. For some reason, the keypad wasn’t properly locked and I had emergency contacts open. I remember that there was some issue with responsiveness in that section. (Also I’d prefer not to make accidental emergency calls so easily.)

@sharethewisdom You can send the file with the logs using Mudita Center.

How to send logs to Mudita via Mudita Center

In a few posts I’ve asked our Mudita Pure Users to send logs from their phone to Mudita vis Mudita Center in order for our tech team to get a better idea about any given issue that you might be experiencing. Here is a step-by-step guide how to do it: connect your Pure to a computer where you have installed Mudita Center. Open Mudita Center (make sure it’s the most recent version of Mudita Center). Once your phone is connected in Mudita center, click “Help”. A new window will appear. Click th…

Thanks, though I prefer to read the logs myself.

At some point in the future, I’ll need to be able to debug the OS myself. Customer support may no longer be available after a few years, and I’d like to be able to compile and upload my own OS fork to the device by then.

A lot of effort was put into the project by Mudita. It would be great if a technical community could carry some of the maintenance burden. I’m honestly not sure why the Mudita center program is used; could the Arduino IDE and “common unix tools” not serve a similar purpose to interact with the Pure phone?

@sharethewisdom
Fair point.
I will pass this on to the team.
