uConsole Notes

Batteries

I use two XTAR 16850-3500 cells and I get about 8h of active usage out of them.

Get GNOME Shell and GDM3

sudo apt install gnome-shell gdm3

Installation with new image

Download image from uConsole github. Unzip with p7zip:

$> sudo apt-get install p7zip
$> p7zip -d uConsole_CM4_v1.3g_64bit.img.7z

Find the SD card, probably at /dev/sda. Write image with dd:

Pocket Chip Debian 10 Upgrade Guide

The purpose of this tutorial is to walk through the required steps to upgrade NXT chip (or pocketchip) from debian jessie to debian buster.

If you would like to start your Chip from scratch, follow the steps in the Preparation section.

Preparation (Optional)

A linux host machine, recommended Ubuntu 18.04. However I managed to do it with 20.10 with some tweak.

Originally from: https://raw.githubusercontent.com/systemik/pwnagotchi-bt-tether/master/GPS-via-PAW
Systemik made the original code and shaynemk on the pwnagotchi boards added timestamps, altitude, and satellites to the code
You can follow the original guide if you want, this one is just using a bit different code and is typed out a bit better
This is just the android part of the whole guide but the rest can be found here https://community.pwnagotchi.ai/t/setting-up-paw-gps-on-android
And just so everyone knows, me (Arttumiro) didnt do anything coding related at all, i just changed up the guide a bit and made it easier to follow.

======================================================================================

Site of the app I use : http://paw-android.fun2code.de (It needs a lot of permissions but it will not do anything automatically)
Dont worry about incompatibility warnings, the gps code should still work even with that.

How To Make A Working TWRP Device Tree For Your MediaTek Device & Start Building Them, Online

This Guide is tested on 64-bit mt6735/53 chipset device. It will also work on any 64-bit and 32-bit devices.

You will need something from your Stock ROM first. Get them all and Try to modify it using the procedure.

Note: This guide will be helpful for you if you have older mediatek devices (android-5.1 or android-6.0), but up-to-date devices can also work.

Update: This guide had a few typos and derps (Oops..), but I've tried to make it free of those now (Dated November 18, 2020)

Bonus: You can also use this tool by @SebaUbuntu, @yshalsager and @mauronofrio to auto generate the twrp tree. The tool is best if your device runs on android-9.0. The tools is still not 100% compatible to all devices, but I'll still recommend it and give it 8.5/10 in the scale of varsatility.
