Backup

{{Info|A backup of the content of the internal eMMC before any of the unique data gets messed up is mandatory. Especially the first 64 sectors of the eMMC and the waveform partition contains data unique irreplaceable data to your PineNote and must be backed up.

Depending of your personal level of data hoarder you may want to backup more than this or even just everything (the large userdata partition is supposed to be able to be repopulated as empty space by Android)

In any case it is easier to restore/extract data from a backup than not having one if you need one.

Manually using rkdeveloptool

Dorian has some nice notes regarding the PineNote

Don't forget to install a patched U-Boo for reading beyond 32MB and to respect the 2GB limit/bug of the current rkdeveloptool as per his notes

Build rkdeveloptool:

git clone https://gitlab.com/pine64-org/quartz-bsp/rkdeveloptool.git
cd rkdeveloptool
mkdir build
cd build
cmake ..

Download mode Enter the download mode by placing the pen as pictured below. A magnet placed where the pen's cap is should also work (haven't tried). I guess the dot on the case also indicates the position of the sensor.

placing pen on the back

lsusb should now recognize the PineNote as:

Warning: this process is very new! Proceed at your own risk.

See instructions on this artifact. It will instruct you on extracting the rootfs into an empty ext4 partition. This can be done from Linux or Android. Further instructions on building your own rootfs can be found here.

Automated backup using a script and rkdeveloptool

pinenote-backup is a python script for detecting the partitions and automating the backup of partitions or the whole disk.

It also requires a patched u-boot but automatically handles the 2GB limit by splitting up larger reads into smaller ones

Using the factory Android installation

TODO

Using a user installed Linux

A Linux installed to the cache partition should be able to easily backup everything over WiFi or to a USB stick/disk using dd.

However the user would need to backup the cache partition themself (if they want that).

And more importantly they would only be getting the backup after they started playing with the content of the eMMC.
