Android

Which version of system do you use? Please provide the version of the system here:

14 from OOWOW, the newest

Please describe your issue below:

Hello! Recently I thought of swapping my Ubuntu for Android, and after the initial boot (which went fine and I would get in), the board won’t boot.

I tried both of my powerbanks and the charger, all of which were working before, and both usb-c ports.

After I plug the cable in, the power led flashes for a split-second, then nothing. If I press and hold the power button, after several seconds, the power led starts glowing red.

I am not able to actually power it on afterwards, and the key combination for OOWOW doesn’t do anything, so I don’t know where to go from there.

@Narrator ,

We have tested the edge2-android-14-v250708 version in our office and it appears to be functioning correctly. Would you be able to provide a video to assist us in our troubleshooting?

I realised that the led flashing at the beginning was so brief that it disappeared after I reduced fps from 30 to 24 to make the video smaller.

I edited the video, but can’t post it again from the same site and now my original post got hidden too.

What to do? I don’t have an account in any video sharing platforms…

@Narrator ，

That is indeed a rather unusual issue. Are you following the operations in the video below, where the device fails to boot after updating the Android system?

  1. Can you connect an HDMI display to check if there is any output?
  2. Can you flash the system via USB?

Hello!

I looked at the video, but I’m not able to access OOWOW via the key combination at all. I have a suspicion that the upgrade mode probably won’t either if OOWOW won’t load.

  1. I have been using a m usb-c display, and it does not show anything, and there is no moment in which the fan would start running. (Under normal circumstances it does a short burst when the system starts booting)
  2. I can try to trigger the upgrade mode based on that manual, once I get back home. I don’t have a regular computer as the Edge2 was supposed to act as one before I discovered the limitations it has as an ARM device, but I have a Rpi4. Can one fastboot into the Edge2 using a Pi? If not, I will have to wait. I will have a laptop delivered later this week.

Hello,

I am unable to enter the upgrade mode either.

Could it be an unfortunately timed hardware fault?
