[Resolved] [Q] Problem identifying Chinese Tablet - General Questions and Answers

I have been a reader of the forum for a log time but until now need your help to identify a Chinese tablet that a friend of mine received as a gift.
The problem is that it is locked in the boot (it only displays Android on screen) and I need to reinstall it and the only information I have is what dmesg returned when connected via USB
:~$ dmesg | tail

I already try to find the serial number and the manufacturer on google but can not find anything related. I took some pictures from the tablet and the box you can find them here -> imgur.com/a/I2k3Y
Thanks for any help
SOLUTION
I posted the same question in StackExchange -> android.stackexchange.com/questions/64892/help-identifying-tablet and it's working now

Help with usb serial device

Hi, when i connect an Huawei 3g usb dongle i see this in dmesg:
[ 2706.844241] usb 2-1: new high speed USB device using tegra-ehci and address 7
[ 2706.876571] usb 2-1: New USB device found, idVendor=12d1, idProduct=1c05

but i can't find the associated device under /dev (I guess it should be ttyHS[X])
Thanks for any help!

[Q] Linux - Mounting SD card over USB?

I've hooked my new G2x up to windows, installed LG drivers, and get two separate drives to access Internal memory and external SD card.
However, when I hook it up to my Gentoo box, It only seems to recognize internal memory.
Looking at dmesg, here is what seems to be the relevant output:
Code:
usb 2-1.5: new high speed USB device number 3 using ehci_hcd

I assuming I'm at least missing a kernel module. Any ideas as to which it would be?
(Kernel 3.0, udev+udisks)
This is just a guess but do you have "ntfs-3g" installed on your box?
Yes, I do have two partitions mounted with ntfs-3g.
Is this an issue/conflict?

[Q] USB OTG Mount JNI errors

Ok not your usual thread. Have the USB OTG Y cable, drive is getting power, tried using a usb hub as well for testing to see if that made a difference (a forum topic seemed to indicated it did) got the same results.. The drive is recognized by the device in dmesg logs, however on the android logcat it is not. It throws a JNI error. I have logs for both.

Through various USB programs the most common error seems to say the kernel recognizes it, the linux system has the pointers and classes but the Android side does not recognize it. Therefore it can only be mounted.
This also appears for regular plugged in usb devices as well mice, cameras etc.
Test was duplicated on original 4.0.4 rooted, PacMan Rom, and LiquidSmooth. Respective kernels that came with those roms as well.
I've attempted to do alot of research into getting this to work. Any help would be appreciate thanks!

Could this be Kernel related? Running 3.0.8, Cyanogenmod 11 Unofficial Edison 2014-03-27

At this point im thinking maybe it wont work on 4.4.2 possibly? May need to go with 4.3 or lower? Or do I just need to go searching for a different kernel? I mean ive tried two so far and no luck. BTW Pacman rom listed previously was 4.3

Now on Paranoid Android 4.2 [4.4.2] Beta3
PA_Edison-userdebug 4.4.2 KVT49L
Anyone have anything? Firmwares that have worked kernels that have worked for them? Anything?
I mean ive even tried 3 different ways of hooking it up.
-Powered usb hub.
-OTG Y cable
-OTG Cable with Manual 5v power to the cable itself.
Ok so nobody has anything? Is this something that just does not work at all with the Atrix 2?
Current trying Mokee 4.3 August 26th build. No dice, JBX kernel install is next.
Again if anyone has any experience with this I'd appreciate it if only to send me off in the right direction or just to confirm it doesnt so I can stop trying. Thanks
OK nevermind then.
Thanks to some great support from Chainfire who created USB Host Diagnostics app for android. I was able to search for successful OTG test instances on the Atrix 2. Looks like the only successes documented in the database were for the stock 4.0.4 Atrix firmware and lower. No support or success for anyone who submitted on custom roms.
Good basepoint, ill be going from there in figuring out how to get it to work.
In case anyone new is wondering. Atrix 2 does NOT have USB OTG working for any custom at all. Even with powered usb otg host cable. No configuration will work at all. Must be something that never made it to the custom roms at least from 4.3 onwards.
For now you will have to have stock firmware and custom kernel for said stock firmware.
Thats all for now. Hopefully those searching will find this useful at least.
