rkdeveloptool: https://wiki.pine64.org/wiki/PineNote_Development#Using_rkdeveloptool

1. Backup uboot
Got into download gadget mode (pen/magnet on back, facedown, reboot).
> rkdeveloptool list-partitions
> rkdeveloptool read-partition uboot uboot.img

2. Patch uboot
Use https://github.com/DorianRudolph/pinenotes/blob/main/py/uboot_img.py to patch
or directly https://github.com/DorianRudolph/pinenotes/blob/main/static/uboot_patched.img

3. Flash patched uboot
rkdeveloptool write-partition uboot uboot_patched.img
rkdeveloptool reboot

4. Backup other partitions
Reboot into patched download gadget mode
List partitions
run `rkdeveloptool read-partition <part> <file>` for all partitions

5. Reboot into system

6. Enable ADB
* Application icon (4 squares) in the top
* Application management
* Application message
* 3 Dots -> Show System
* Search for "Settings" and open
If it doesn't work, set "Default USB configuration" to PTP, then re-enbable ADB

7. Root via Magisk
https://topjohnwu.github.io/Magisk/install.html#patching-images
Right now, we need to use Magisk build c85b2a0 (https://github.com/DorianRudolph/pinenotes/blob/main/static/magisk_c85b2a0.apk) as discussed in the issue (many thanks to canyie for fixing this so quickly).

```
adb push boot.img /sdcard/boot.img  # d60f4054edb91259fb4471eb5f0ba53803b9a7e2300c3647e11f7b71aa95a003
adb install magisk_c85b2a0.apk
```

Patch the image on PineNote in Magisk

```
adb pull /sdcard/Download/magisk_patched-23011_dhTkI.img boot_magisk.img
```

Reboot into download gadget mode

```
rkdeveloptool write-partition boot boot_magisk.img
rkdeveloptool reboot
```
