PinePhone EG25 automatic test failed

[henkdieter]

Hi,
Yesterday I received my PinePhone. Really love the build quality! As you know, it comes with just the factory test image flashed. Going through all the tests, I found out that the EG25 modem automatic test failed. I've been trying a couple more times, but it keeps failing. Is there anything I need to do to make the test pass, or might the modem be broken? Or am I just being paranoid?

Guess I was paranoid after all. Just needed to insert the SIM

Have you inserted a working SIM card?

I'm in the same situation here, although all automatic tests passed when I got the phone a couple of days ago. Now the factory test gives a fail for EG25.

I have got it working with Ubuntu Touch for a while (booting from MicroSD), but the phone suddenly shut off. Now I get to the Ubuntu Touch loading screen (which looks a bit wierd graphically) for a couple of seconds until it  suddenly dies.

I'll try to recapitulate all the things I've done since I got the PinePhone:

1) I removed the battery sticker after removing the battery which was sitting very tight. Had to use a plastic tool but it seemed to work just fine.

2) Booted the preloaded image successfully. All factory tests passed except for the SIM card status (which I was expecting after reading the forums since it's not yet unlocked with the four digit code).

3) I flashed the latest Ubuntu Touch image from the UbPorts download page to a 256 GB MicroSD card.

4) Successfully booted Ubuntu Touch from the MicroSD card. The loading screen looked a bit wierd. Once inside the OS, the SIM card was not recognized (again, as expected), otherwise all seemed fine. After playing around with the settings for a while the phone suddenly died. It happened when I adjusted the screen brightness. Battery showed 65 % left.

5) Tried a couple of times more with the same setup, now crashing at the Ubuntu Touch loading screen.

6) After removing the MicroSD card and running the automatic factory tests again I get a fail on the EG25.


Does anyone have an idea on what I should try next? I really hope I haven't accidentally broken the phone somehow. All suggestions are greatly appreciated.

What does the factorytest image show on the modem page instead of the automatic test page?

[ThownAway]

Very wierd. I tested again right now, with usb-c power adapter plugged in, and the EG25 says OK while RTL8723CS says failed.

The modem test gives

Modem status:

Status: OK
etc.

Sim status:

Status: Connected
etc.

Call status:

Status: Ready for call
Technology: ...
Number: ...

Any ideas?

Just received my phone 4 hours ago.

I run automated tests and these are failing:
EG25
RTL8723CS

Others are ok.

I tried to search but could not figure out if this is normal behaviour?


https://wiki.pine64.org/index.php/PinePhone
Wiki says:
"It's also important to note that the EG25 modem and RTL8723CS wifi/bluetooth do not work without the battery plugged in, even if you are supplying enough power to the Pinephone with USB-C"



So I guess when I have battery on those should work?

And also I installed latest UBports which says wifi should be working.

But with quickly testing wifi is not working for me. Is it working from GUI for others?


I need to continue troubleshooting tomorrow...

A quick update:

I can't really explain why but after a couple of reboots (without SD card) I suddenly got OK on all automatic factory tests. I instantly flashed the most recent Ubuntu Touch build and plugged in the SD card. Pretty much exactly the same thing as described above happened again; weird looking loading screen with the Ubuntu logo messed up (just me?), and after fooling around with the settings it crashed when I was adjusting the brightness. After that it crashes directly on the loading screen.

However, I also tried with the latest PostmarketOS phosh build. From what I can tell, it seems to work just fine.

Could this somehow be a OS specific (Ubuntu Touch) problem related to the unlocked SIM card? Should I bug report directly to the Ubuntu Touch developers?

My time is limited right now but I will do some more testing in the coming days and keep you posted.

Exactly what happened to me in every single detail (except that eg25 problem is solved if you insert a sim card which doesn't require a pin code).  It looks like brightness is locked at 0% and you can't see anything anymore... imho the system is working, i pressed several seconds the power button and tapped randomly on the screen and it restarted: with black screen again, as a result

I run automated tests and these are failing:
EG25
RTL8723CS

Inserting SIM and I got EG25 test to pass.


Got help from customer support and this might help others as well.
If RTL8723CS is failing:
"make sure there is Wifi router around 5 meter rea when perform this test, the Wifi test function sniff for SSID to determine test result during autotest. The Wifi can fail if the battery power is too low. "


But in my case RTL8723CS still fails.
I tried with battery full and charger on but still automatic tests fail.

Need to continue testing.
