I've been using my PPP as a daily driver now for quite awhile and utilizing the S20 Ultra battery case mod.   The combination of 3000mAh internal battery and the 6000 mAh case battery gives me enough for my normal usage.  

Now, I have a strong electronics background but have little experience in lipo batteries, so my question is this:

I've looked at the schematics and it looks like 3 of the 4 pins on the J7 battery slot are connected: +, GND, and TS.  + and GND are self explanatory.    TS looks like its a thermistor connection to monitor the temperature of the batteries.   If that is correct, then there are several larger "3 wire" lipo batteries that I could utilize, or make my own with individual cells and the appropriate balancing circuit. 

So, my questions. 

Can I install a custom battery into the pinephone using the same battery connectors, and will the software/hardware be able to deal with the larger capacity of the batteries?  

For those with experience with lipo batteries, is it really that simple, or is there more to consider other than temperature and balance?

Thanks in advance.

Edit - I linked to the PP schematics, not the PPP. Fixed.

Hi,

I've tried to get a quartz64-A up and running with numerous images (manjaro, plebian, gentoo), and I'm not getting any response from it. The power LED comes on and some of the images light the heartbeat LED, but I don't get a video output, my router doesn't detect a new device on the network (I've attached it via ethernet), and I'm not able to get a response from the uart/usb interface (I'm new to uart, so I'm not 100% sure on this point). I've tried booting off a eMMC and microSD. I checked the microSD with badblocks to see if it was corrupt, but it checks out.

Any recommendations?

I have trouble getting pine phone pro to boot after flashing the eMMC.  I am using towboot.

Using the published instructions below from the wiki, I boot from the SD card using Kali.   Downloaded a two images Mobian and Ubuntu touch .  used dd without issue while booted from SD card.

On reboot, it fails to boot. Tried both Mobian and Ubuntu touch images. I did extract to the .img file and not flashing the .xz or the .gz version of the image.

OS

1. Flash an OS to the microSD card (and optionally resize the partition, see below)
   
2. Insert microSD card and boot the phone
   
3. Download the desired OS' image on the booted OS or transfer it to the microSD card
   
4. Extract the image file if it is archived
   
5. Flash the image file to eMMC using 
   
   
   Code:

   dd if=IMAGE.img of=/dev/mmcblkX bs=1M status=progress conv=fsync

Is it possible to reuse the SoC debug UART as two independent GPIO pins that can be controlled from Linux? If so, how?

Near the connector for the keyboard ribbon cable, there is a set of three though-hole pads labeled Rx, Tx, and Gnd. Is this the debug serial port from the SoC before it is multiplexed with analog audio on the 3.5mm jack?

What makes PinePhone a phone? It’s the 4G LTE Modem inside that makes Phone Calls and sends Text Messages!

Now we’re building a Feature Phone with Apache NuttX RTOS (Real-Time Operating System). To make things simpler, we’re writing down everything we know about the 4G LTE Modem, and how it works inside PinePhone…

Hello,

I'd like to install Ungoogled Chromium on my Manjaro Arm Phosh Pinephone.  I don't see it as an option in Pamac and have read elsewhere that downloading software risks fatal partial upgrades (as I understand it). 

Can anyone advise me as to how to safely add the repository to Pamac or otherwise safely install this application?

Thanks in advance.

Hello everyone, I would be very happy if there were programmers who would make a finished uefi bios, download it and install it on the spi or sd card without any effort, I've had denrockpro64 for a very long time, it's very tedious, the images are pretty bad, old kernel, with uefi could i install the latest linux myself using iso or windows 10, i don't want to throw my rockpro64 in the trash.

Hello everyone,

The PineTab-V and PineTab2 will be available for pre-order on Thursday, April 13th.

I have just received the phone, with Manjaro-Arm installed. I've got the contacts moved from my Android phone and the voice part is looking good. It also goes on Wifi and thus to the Web OK.

However, I've sent an SMS from an SMS API and this hasn't turned up anywhere. Also I'm getting
