Hello I have an nice phone

ULEFONE Power Armor 13

Good specs etc

Recovery:

boot menu: hold power and vol up. when phone vibrates to boot up relaes power and keep holding vol up (caused by the pu button being held constant during bootup)
- in this mode fastboot lets you flash with adb
- recover boots recovery image
- normal is normal boot
to boot right into recovery
- hole power off and volume down release pwoer to stop reboot
- once you see logo you can release vol down and it will enter recovery boot

Recently iv had some problems with it and the os has been corupted. I blame spyware

I am about to recover my photos off of this device and then root it with a stock ish android

Im a noob at android development/hacking so would like to document my learning joruny for you

First install adb Getting ADB (Android Debug Bridge) working on linux can be a bit harder than on other operating systems. This guide aims to help with that.

Installation

https://gist.githubusercontent.com/isti03/4104cc33dbf5b741add2a27c8d3a41df/raw/3e7e21bcd0108188628a035f7c8f4fdf447d3f04/adb-linux.md https://forum.xda-developers.com/t/guide-linux-installing-adb-and-fastboot-on-linux-device-detection-drivers.3478678/

1. Install the adb package

Just use your package manager

sudo apt install adb
sudo apt-get install android-tools-adb android-tools-fastboot

https://spflashtools.com/linux/sp-flash-tool-v6-2124-for-linux

2. Add yourself to the plugdev group

sudo groupadd plugdev
sudo usermod -a -G plugdev $USER

Then reboot

3. Enable Usb debugging on your device

See https://www.getdroidtips.com/enable-usb-debugging/

4. Connect to your device

Unlock your device
Run the command adb devices
Authorize access on a pop-up on your device
Re-run adb devices. You should see your device id, and device next to it.
If you get an error, no permissions (user in plugdev group; are your udev rules wrong?), install the android-udev package and reboot.

to enter chineis menu hold power and vol down when you see the screen relaeas volum down and then power
