mirek v7 working great on HG9M

So yeah, after going through this thread and the rom one I flashed my HG9M to mirek's android 5 v7 and all seems to be working well.

I'd like to add a small noob "guide" describing my steps to (maybe) help others going through these messy forums. It's not really a guide, and I won't be explaining anything myself, I'll just try and gather the resources I used in a fashion I found to be easier to work with.

The process is basically as described in mirek's thread just slightly more detailed. So:

First I installed the adb drivers for my pc using this tecknight's tutorial. You can instead use the .exe's included with the rom files to achieve just the same. (make sure you chose the right files for your tablet)

.

Then I shut down my tablet from android (tecknight recommend it somewhere) and entered dnx mode - which took several tries to achieve.

Finally I ran the flash tool .bat ,using my windows 10 pc (no problems there), chose to clean install - it ran, and then booted to android successfully.

You can also install the MFT using tecknight's guide (see the changelog part as well) although not necessary for the v7 rom according to mirek.

What else / why flash?

(short story time :p)

Even before getting the tablet I started reading through the forums getting the impression that the tablet will be greatly improved by flashing mirek's rom, followed by flashing the bios to 2.02 and finally by upgrading windows to 10. Tbh, the tablet (my version at least) worked pretty good as it was the way I got it. I still wanted to try flashing at least to get the latest android available, but the state of these forums combined with the lacking or conflicting guides (which were often all working) and finally the numerous bricking reports were all very discouraging, and so I decided to stick with stock for a while. I found myself using mostly android - a matter of preference, even though windows 8 always worked great, aside from the faster battery drain. I finally decided to flash the rom, mainly for these two reasons - the sound (which was better/louder under windows) and the youtube app which couldn't play videos in hd. Now I must say, mirek's rom improved much more than that and has indeed made my experience a lot more pleasurable.

Here is a list if things you'll get with this rom which makes it worth it imo: (repeating myself a bit)

Root

The sound - with the preconfigured viper, which works great.

Youtube - now working properly

Smoother and more responsive UI - idk how, but I feel a dramatic improvement here. Ex: Under stock scrolling was terrible, with mirek it's pretty good. Under stock, I couldn't use swipe keyboard properly, I actually thought it was the touchscreen quality which sucked, but again, under mirek it works well.

That's it I think, I rambled too much anyway, if I ever feel like flashing the bios will serve me better and is worth the risk I'll add it to my "guide" here (I haven't even checked the version yet).

Btw, both my cameras are working great.
