Recovering data from Android phone with a broken screen
Here are my quick notes in order to share and remember.
There was an XiaoMi 4 phone with a broken screen and data on it.
First prepare a cable to connect the phone with the computer.
Then download the right recovery image for the phone and boot
it by switching the phone into fastboot mode (hold volume-down
button while turning on) using fastboot boot recovery.img.
Then use adb to connect to the shell. Oops, does adb say
there are no connected devices? Boot with systemd or other
udev-friendly beast which makes use of the android.rules
file (on Arch Linux installed by android-udev package).
By using adb shell do some magic with tar and uuencode.
Then uudecode it on the local side of the pipe and check
the local tar understands the data that are coming.
