Boox Page adb / fastboot / recovery /edl walkthrough

Hi,

I recently purchased a Boox Page (QC Snapdragon 662) and decided to play a bit with it and find out the different boot options.

Goal is of course to be able to backup and restore the firmware images in case some experimentation go wrong.

So far, different boot modes I managed to get into (Page running the 3.5.1 firmware):

First, enable adb*:
- Open Apps tab
- Top right menu ⇒ Manage apps
- Then enable Android Debug Bridge (adb)

Boot into bootloader (Fastboot)*:
- From adb ⇒ adb reboot bootloader
- From recovery => Reboot to bootloader

Boot into Recovery*:
- Command line*:
- From adb ⇒ adb reboot recover
- From bootloader ⇒ fastboot reboot recovery
- Buttons*:
- Poweroff the page (unplugged)
- Press power until blue led turns on and keep pressed for 7 seconds then release
- Right after, press and release power 5 times
- Your device should enter recovery

Boot into Fastbootd*:
- From recovery ⇒ Enter fastboot
- From adb ⇒ adb reboot fastboot

Boot into EDL (9008):
- From adb ⇒ adb reboot edl
- Buttons ??

Exit from EDL (9008) ⇒ Press an maintain power button for 10 to 15 seconds.


Now, I am stuck playing with edl mode. Under Linux, I have tried but can't get the https://github.com/bkerler/edl to work (some python issues on both Archlinux and Debian).

Under Windows, I have tried @Renate edl utility (http://temblast.com/edl.htm) but can't seem to find the right driver using Zadig to make it work. It keeps saying "Can't open device".

Questions:

- Is there any other way to get into edl mode than from adb (fastboot oem edl or fastboot reboot-edl don't work)?

- What am I doing wrong with Zadig (WinUSB-lisusb, libusb-win32, libusbK did not work, WinUSB-serial failed to install)?

Thanks!

Edit: Added a list of the Page partitions. It's a AB device with a super partition.
