Let's root the Max Lumi 2

[beigewell]

is there any way to flash the Max Lumi 2 when you do not know the password? I cannot logon to the device and factory reset only takes me to the Android Debug screen and displays "no command"

[Renate]

Well, there is always a way to get this sorted out. It's a question of effort.

First, is the USB ever active and what is it showing?
On Linux, do a lsusb command, on Windows check if it "bongs" when you plug in a cable and try adb and fastboot, look in devmgmt.msc, try my UsbLog.exe

[beigewell]

If I get the device into the recovery mode I can, it shows the Android "No Command" screen. I can connect it and use adb devices (on Windows) I can see the device it is just listed as "unauthorised" (because USB debugging isnt enabled)

[beigewell]

adb devices lists the device B5C584D4 and "unauthorized". Fastboot doesnt detect. DevManView shows the device MaxLumi2 as a WinUSB device

[Renate]

You must be in stock recovery. That has that silly secure adb.
If adb was not enabled you wouldn't even see it.

You don't have any on screen options?

I don't know how easy the Max Lumi 2 is to take apart, how well you do that and how you feel about it, but we do have an EDL loader for this and you can surely fix it.

If all you can get to is unauthorized adb and there's no fastboot and you've tried playing with buttons and still can't get anywhere, then you'll have to try something else.

Some people, some other manufacturers have success with "EDL cables". I've built one, never got it to work on anything, but that could be my fault too.

[beigewell]

no the buttons only get me to the Android "no command" screen. In fairness Boox have offered for me to send it back to them to get reflashed and only pay for shipping. Seems best option when factory reset with their instructions doesn't work. thanks anyway

Aw, I would have taken this apart.

I believe most stock recoveries have ro.adb.secure=1 which means they require adb_keys.
Since recoveries generally don't have the adb socket to trigger the confirm popup there is no way to add keys.
The Onyx stock recoveries don't have either /adb_keys or /data/misc/adb/adb_keys (obviously) so there are no OEM keys.
If they did have OEM keys they could probably flash your device without opening it.

So, the question is: Can they flash it without opening it?
If this were my device I'd put a little dot of clear nail polish on a seam to see if they break it.
OTOH, I wouldn't send it in, I'd just open it.

Hey,
I used your guide to root my Max Lumi 2 v3.5.4 (replacing fastboot with edl), but my device is still not rooted. This also happened the last time I tried to root, like a month ago.

./adb shell
BOOX:/ $ su
Permission denied

AFWall+ still can't aquire root access.
Root did work on v3.5.3
Please help

[Renate]

There's permissions settings in the Magisk app for su in shell.

Here's the logs:

Every time I try use access su, I waits for 30 seconds then refuses.

[Renate]

I don't use Magisk.

[richard.black]

Can you guide me how can I root my device without magisk?

[Renate]

[richard.black]

It is set to Apps and ADB.

[Renate]

I dunno.
