I lost USB ssh access after a recent update (including kernel as I remember) into my UBPorts edition. Can't see the phone by lsusb, ip a, or dmesg. The situation is the same independent of OS (including postmarketOS without UI), either running from eMMC or SD card. Inspecting the initramfs via the debug-shell would not work. PostmarketOS troubleshoot suggests adjusting kernel configuration parameters referencing: CONFIG_USB_ETH CONFIG_USB_ETH_RNDIS CONFIG_USB_G_ANDROID.  Anybody know the appropriate parameters I should be looking for?

So I saw this tweet: https://twitter.com/LukaszErecinsk1/stat...3589531650

I tried to enable WebRender on my Firefox but it seems to fail to start up. I could make it past the start up if I overrode OpenGL version to 3.3 but Firefox becomes a huge graphical mess, so not really any better. I'm on Wayland, default Manjaro install, mesa-git driver.

in aboutupport I see this:

unavailable by runtime: WebRender initialization failed
(#0) Error Failed GL context creation for WebRender: 0

Anyone get it successfully working? Is it worth pursuing for the performance increase?

Not sure if anybody is curious or interested, but MS Powershell 7.0.3 works great out of the box on Manjaro KDE and PBP. (I have to use it for work now and again)

I've come across a few posts about there being possible corruption of the firmware on the Pinephone modems. Are the only affected ones the one from the Braveheart Editions or does it occur on the UBports editions as well? Im not sure whats the deal with my UBports edition phone. It was not working when using UBports and even when it was updated I still had no cellular working. Then I tried Mobian and still it was not working. I ran the hardware test from a Postmarket OS image and it shows the modem status as ok.

Factorytest v0.49.0
Status: OK
Registration: not registered
IMEI: XXXXXXXXXXXXXXXX   (it shows but Im not posting it)
Firmware: EG25GGBR07A08M2G
Network: FDD LTE, 311480, LTE BAND 13
Signal: -81dBm

Sim Status
Status: Connected
IMSI: XXXXXXXXXXXXXXXX

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

Im not sure what to make of it, with Mobian and UBports not working with my sim. I have thought if the results from the modem are faulty results.

(Edit 1) My cellular service is from T-mobile and I used a T-mobile sim card.
Edit 2:  Sim card size is micro

Update:
https://www.t-mobile.com/support/coverag...le-network  a link to T-mobile network bands.

Does anyone know if it might have something to do with the Network bands T-mobile uses in the Los Angeles Area?

Update: I installed and used LTE Discovery on a working android phone and it shows in my area that it connects mostly to band 2 and sometimes 66. Band 66 is not supported by the EG-25G modem.

Anyone know how to keep the modem to refuse or stop trying to connect to band 66?

Hi, all. To resolve another issue, I need to load up a rescue boot loader onto an SD card and look at my Pienbook. And I have to pray that it will boot to it without my manual intervention because right now the screen is refusing to light up. 

The boot loaders I've. seen are installers for other Linux distros, and I'm supposed to run something on the Pinebook to generate them. That is not an option. I have a Mac, and I have an old Linux Intel machine. I need to download either an image and put it on an SD card, or generate it and put it in, but it can't be on the Pinebook at the moment. What are the options?

If that boot loader is also an installer for a Debian/Ubuntu/etc distort, that would be a bonus, as I think I'm about to bid farewell to Manjaro. Thanks!

I'm sure I'm not the only one who wishes they can write their own OS

I've written code for an Arduino to communicate with a qualcomm chip/modem to receive and send SMS using AT commands. 
I wanted to try a from scratch for the raspberry pi but it seems like I'll get poor video performance because there's no documentation for using their GPU/video

I was wondering if there's a lot of linux that's required to get the phone running and if not would it be possible to write our own OS or embeded like as people may do for the Arduino?

Hey there. I hope I can get a bit of inspiration for further problem shooting for my seemingly dead pbp. LEDs turn red then green(solid) as expected but screen doesn’t turn on at all. All worked perfectly until I wanted to test Manjaro i3 from SD card. I have Manjaro KDE  on eMmc installed already. Ok booted Manjaro i3 from SD card all worked fine. I updated this distro installed a few things from repository and built Vivaldi browser from AUR using Parmac. Then when rebooting I got the issue above. I thought there was something wrong with SD card and ejected and re booted only to see same issue with my installed system - nothing boots. I tried to charge in full then let it go completely flat in case of some endless sleep cycle ( this took about 20 hours). Any suggestions why the screen is just completely black? I know very little about things like gpu etc. so don’t know if any faulty hardware is preventing something to start screen? I’m really at a loss - I haven’t touched the hardware inside I have only flashed a card. SD card 32 gb and worked fine when I had Debian and Manjaro KDE on card. Any ideas??

Hello, dear members,

my name is Costa, I'm living near the Northern Sea, and I've been longing for a mobile phone like the pine 64 for ages.
Would you be so kind as to answer me some questions:

First of all, I assume there are differences concerning the frequences used for phone calls, right?
Does, for example, mean the term 2G mean the same in the US as in Europe?

In other words, could I fail in unpacking the phone, putting in my ALDIDALK SIM-card and phoning a good friend?

As I'm wearing glass-bricks due to my myopy, maybe I didn't look at the right places?

Thanks in advance for your answer.

Best wishes,

Costa

Hi all, i've recently, thanks to a guide posted on OMGUbuntu, changed my Firefox renderer over to the new Rust based, GPU bound one and it has literally been night and day in terms of performance. I'd highly recommend you do the same. 

https://www.omgubuntu.co.uk/2020/07/fire...nder-linux

Yesterday I installed the new Firefox like described in the wiki (https://wiki.mobian-project.org/doku.php?id=webapps). Later in the evening I noticed that an upgrade seemed to be ready. I took the upgrade via the software app only to be greeted with the same upgrade notice after a reboot.



I've since uninstalled Firefox and removed the sid repo and also the priority pinning. 



Trying to upgrade from terminal shows this:

As you can see, the versions to be installed are the same. Still it believes the packages are to be downgraded. I've also tried to see what happens with "dpkg -i". How to I get out of this loop?



Thank you.
