Notsure Rooting MyAudio Series9

I recently bought my new android tabled, and since I'm a curious, adventurous person, and I like to have the complete freedom of my android device, I wanted to root it, but by hand.

Soon it turned out that I have no other choice anyway, and also had very few article covering this topic for this tablet. The no choice come from the fact, that ADB is unable to connect to my device, no matter what OS or Driver I've tried. I've already downloaded the su binary, and for curiosity I've pre-installed the Superuser and Busybox apps from google play.

After a few hour of struggling, I've rebooted my tablet in recovery mode, and a dying android figure appeared it's stomach open, all the currents visible inside, and a red triangle, with a black exclamation mark inside, but I was missing the menu. For a short while I was able to see it, but immediately restarted (probably activated the menu item) and I couldn't make it appear again.

I was able to connect ADB in recovery mode, but 1. /system was not mounted, 2. with exception of the first restart, I only could restart the tablet with `adb restart`. After a few power/usb unplugging and restarting to recovery and normal mode (I bet this is the bootloader mode) the screen started flickering. Not too disturbing, and it is not notable on 100% black screen at all, but if it isn't 100% but homogeneous black, like in the settings, the little lying android figure's silhouette can be make out.

I'm kind of worried at this point (who wouldn't) and don't really dare to take to repair it like this. And I did not get closer to rooting my tablet.

What do you suggest to do at this point? Do you think this would fix if it is off for a while, or is there a way to fix it?

Ps.: As I was typing this, I turned it on and the green figure was not visible, but it was still flickering. Also I've jut tried out to turn the brightness level all the way down, and now it is not flickering at all. (Or just not visible?)

Also when I'm charging it the touch screen going crazy (vibrates in one horizontal line, in-between the two short sides), but I think it is because the charger is not grounded, and the power voltage is at 220~240 here.
(I don't know wether this fact has to do with any of the above.)

Also it seems, that the charger animation is not flickering.

Update: After turning back on, the screen did not flickered with full brightness. Also I tried to boot in to recovery mode, and a with a connected keyboard, I could restart with Ctrl+Alt+Delete. Nothing else new yet.

I was diging deeper on the topic , and find a general guide here on the forums, that discussed the steps that should be considered, and it stated to backing up the rom.

ADB could make backups, but that can't access the device (and I can't understand why), and the recovery menu does not appear, make it partially useless (but the fact that there is one might come in handy at the right time).

This (and the guide) makes me think of the following two thing:
1. Rooting is not possible on my device; and I won't take that!
2. I should ask @ the site that was mentioned in the guide, and forgot.

I'll not give up here. Not yet though.
