[Miscellaneous Android Development] martyfender:
I updated the OP a few hours ago:

"UPDATE: I now have root, a custom TWRP recovery and modified boot images for this device.

I am waiting on approval of a developer account to serve the files on Android File Host (AFH) and to prepare necessary documentation. Stay tuned."

I will be preparing a tutorial here, because, one, I hate youtube tutorials and have never done anything like that. This will be long an as thorough because I see so many people who have trouble with this because they don't have their computer setup properly from the get go.

I could post the files sooner on my gdrive, but I would rather wait to get approval of a developer account at AFH. I am not sure how long it take to get approval. My best guess is probably not until after the weekend.

This will help you get ready for the release and the start of my outline for the tutorial.

First and foremost, unlocking your bootloader will delete all userdata on the tablet so you need a good backup of important files. If you backup to an external sd card, I strongly recommend also copying the files to an external source such as your computer. You can do that through mtp or remove the card and place it in an sd card adapter and insert it into an sd card reader. I did not do this, even though I knew better and my sd card was corrupted in the process, so I lost the original twrp backup of the virgin, untouched system partition.

Secondly, if you are on windows you need the proper drivers adb and fastboot installed on your system. Proper drivers are the number one issue I see with windows users. For this Intel device get them here:

The best way to to set up adb and fastboot in windows is to install it system wide. Here is an installer to do this that works well:

Third, enable developer options by going to settings, about tablet, and tap on the build number five times to enable it.

Then go to developer options and make sure usb debugging is enabled. watch on the tablet screen for a popup dialog the approve usb debugging. check the box to always allow for this computer and hit ok.

Now, with the proper drivers installed, adb and fastboot properly installed You need to test that it is fuctioning properly. This is done with the tablet booted into Android. If you used the adb I recommended, go to my computer, C drive and open the newly created adb folder. Left click in an open area of the folder to select it. then shift right click to open a contextual menu, then select: open a command prompt here. Once the command window is open, type: adb devices and hit enter:

you should see the device serial number listed. I am now doing this from linux, so it may differ,slightly:

adb devices

List of devices attached

YFGV1216059870	device

Sometimes you get starting daemon on port... and you have to type it again to see the device listed. If you don;t see this, then your drivers aren't properly installed.

If you see your device, then type: adb reboot bootloader and hit enter. your device should now reboot to bootloader mode. once in bootloader mode, type:

fastboot devices and you device should once again be listed.

The next step, is to unlock your bootloader. Warning: ALL OF YOUR USERDATA WILL BE DELETED, HENSE THE BACKUP CREATED EARLIER. YOU HAVE BEEN WARNED!

Go into developer options and select OEM unlocking. This does not unlock your bootloader, it only enables the ability to do it from a fastboot prompt.

Now, while still booted into bootloader mode, type:

fastboot flashing unlock and hit enter to unlock your bootloader. All data will be deleted and the tablet will be re-encrypted upon boot, without encryption option removed from the bootloader. Now type fastboot reboot, to reboot the tablet and you should reboot to the android setup screen, You can set it up again if you want, but you will be deleting userdata later when you flash the modified boot.img, so keep this in mind. So you may want to wait to unlock until I release twrp and the boot.img, so you can continue using the tablet.

To summarize, the above steps are to prepare you for the next exciting adventure to come and to realize the full potential that a rooted device offers..................

To be continued.
