Since the screen was broken on the Leaf 1 and the Leaf 2 was coming out I ordered the Leaf 2 White.

I will probably root it to install AFWall+ when I receive it. Root would also make it possible to remove all the Onyx Apps completely. (not just for user0 through adb) that might brick the device or make it bootloop. Since there is no recovery it's not possible to make a Nandroid backup and I wouldn't know how to factory reset it. Is there a way to make a backup or flash a factory image just in case?

I would install a different launcher like [E-Ink launcher, 4.2+] Simple Ink Launcher
before fully removing the default launcher of course.

I'm guessing that removing every Onyx app (including the launcher) might break the side-buttons, has anyone tried that?

Just don't disable or delete SystemUI.apk
If you want a recovery I can probably mix up a recovery for the Leaf2 if you want to be a Beta. Get/post a rec.img
If it's not in an update use EDL and copy it from your device.

Sure, I want to be a Beta tester. I'll send you the files once I receive the device. You're intending on porting TWRP or Clockworkmod? Do you use a custom recovery on your device?

It's possible to make a backup image before removing systemapps with root? I guess I could backup the system partition and flash it back with fastboot incase things go south?

No, I just make a minimal recovery with a rooted, permissive ADB. You can still access stock recovery from it.

Just out of curiosity how would you achieve that? Any guides or resources on that?

There are many tutorials on porting TWRP. I find this interesting so it might be fun thing to have a go at later. I can already see myself messing around with it more than using it for its intended purpose (reading).

Just don't Uninstall com.onyx and the NeoReader to let navigation gesture and lock screen work properly(for V3.3 )

Instruction on how I rooted the Leaf 2 can be found here: Boox Leaf 2 general discussion

Does anyone know how I can extract the stock recovery from the device? (It's rooted) I don't find any good instructions on that.

On 3.3.1 I didn't run in to any issues so far. Gestures still work though a navbar appears at the bottom, it isn't visible in KoReader so it doesn't bother me.

I also disabled com.onyx on my Onyx Boox Kon-Tiki 2. Lockscreen and gestures work, however if I need to change them I need to enable com.onyx again.

By the way, pm disable is virtually the same as pm uninstall for user 0. Don’t actually uninstall apks from system, there is verity check upon each reboot. So you might brick device.

@denisuu
To your question about recovery extraction, use edl from GitHub

@renate

I already tried that, it doesn't work.

Code:
PS C:\> adb shell
Leaf2:/ $ su
Leaf2:/ # dd if=/dev/block/by-name/recovery of=/storage/E088-7398/Backup/recovery.img
dd: /dev/block/by-name/recovery: No such file or directory
When I search for recovery, nothing is found either.
Code:
find / recovery
I'm just dumping the whole MMC now.

Code:
dd if=/dev/block/bootdevice/mmcblk0 of=/storage/E088-7398/Backup/mmcblk0.bin

Well, mine's called that.
Code:
lrwxrwxrwx 1 root root 20 1971-06-12 08:48 recovery -> /dev/block/mmcblk0p9
Maybe you've got that new-fangled stuff where recovery is part of the regular boot image.
Did you list out /dev/block/by-name ?

Also, with EDL you can back up directly without using dd or an SD card/flash drive.

Ah I found it, seems there are 2 recovery partitions.

Quote:
Leaf2:/ $ ls -al /dev/block/platform/soc/4744000.sdhci/by-name | grep recovery
lrwxrwxrwx 1 root root 21 1970-01-26 15:09 recovery_a -> /dev/block/mmcblk0p16
lrwxrwxrwx 1 root root 21 1970-01-26 15:09 recovery_b -> /dev/block/mmcblk0p17
I looked in to the EDL method and found it quite complicated. I was able to get the device detected but that was as far as I got. Although dumping the whole MMC took a while, It's nice to have a full dump. I can extract what I need now.

Thanks for the help guys!
