Welcome All, this is my first guide, and most of it comes from other people :p We started with the Viking Pro, but I managed to port all of the work done over to the Maven Pro (almost the same tablet). It's been a lot of fun, and you can read all about it here, if you haven't already.
Also, for the purpose of this guide, I'll assume you already have working ADB and fastboot on your pc, if not, you'll need to set that up first. If you're looking for the guide to the Viking Pro (RCT6303W87DK), go here.
So, without further ado, lets get started. First, you'll want to download the firmware .zip package for the Maven (link below), this is the V36-1.9.21 version, if that doesn't match your version, ask for help before you proceed. Everything is located in the "Images" folder, lk.bin and recovery.img are custom, it also has the original files. The download folder also has the necessary drivers (signed and unsigned), SP Flashtool, and other stuff you may want. If anything goes wrong, you can always flash the firmware to get back to stock and start this process over.
To root the tablet, you should download the Kingroot apk file from here. Either download directly to tablet, of download with pc and put it on your external sd card. You'll have to enable installing apps from unknown sources to install it, Settings/Security/Unknown Sources. After installation, run it, and let it do it's thing, if you don't want to keep using Kingroot, you can replace it with SuperSU by following this guide.
WARNING, Unlocking your bootloader will erase all data on your tablet and do a factory reset! You can use Titanium Backup to backup all your apps, after you have root access, or just let the Google reinstall everything. To get the bootloader unlocked, we're going to use a modified version of the guide for the Viking Pro. The Maven doesn't require a special "Jerry Cable" (male-to-male USB), we can use a micro cable, just like with our phones.
Steps(Windows 8/8.1/10): For step 2 you will have five seconds. Preloader mode is only active for five seconds. So read first!
1- Extract the drivers to the destktop and open the device manager ("right click" on the Start button, select "Device Manager")
2- Plug your tablet in as such: turn off the tablet. Plug in the micro USB on the tablet, the other to the USB port on the pc, now very quickly in the device manager locate the new device and right click on it. Select "update driver software" then select "browse my computer for driver software" and "browse". Navigate to the driver folder, select the "CDC" folder and click on "OK" then "Next". The driver should install at this point. Once that is done, unplug the usb cable from the pc (I find it easier to just keep the micro in the tablet).
3- Extract the firmware and the sp flash tools to your desktop.
4- Start the sp flash tools and where it says scatter file loading click and navigate to the folder where you have the firmware and load the scatter file.
5- Once that is done, uncheck everything, and select "uboot" only, from the list and click on the download button.
6- Plug the USB cable back into your pc. At this point the sp flash tool will load the patched "lk.bin" file to the tablet. DO NOT UNPLUG ANYTHING UNTIL THE SP FLASH TOOLS SHOWS YOU A GREEN CHECK MARK TO INDICATE THAT IT IS DONE OR YOUR TABLET COULD BE HARD BRICKED AND UNREPAIRABLE.
7- Boot into recovery, hold the Volume + and Power button, when splash screen comes up (the 2 dogs) release the power button. Select "Reboot to Bootloader" to get into fastboot mode.
8- Once in fastboot, open a command terminal and type: fastboot devices (to make sure your tablet shows an id)
then: fastboot oem unlock (this will start the "unlock flow", no need to use power buttons)
9- After the tablet gets back to fastboot mode (takes 3-5 seconds) type: fastboot reboot
After the tablet reboots (it takes a bit, remember, unlocking the bootloader does a factory reset), set it back up using whichever method you choose. Note, it is not necessary to re-root, just reinstall the SuperSU app from the play store and update the binary's.
To install the custom recovery, follow the steps above, except choose "recovery" only (instead of "uboot"), to flash. After it's done, you can boot into your new recovery and do a Nandroid backup.

NO'DIS: I, OR ANYONE ELSE, ARE NOT RESPONSIBLE FOR BRICKS, IF YOU MANAGE TO BRICK YOUR TABLET, BUILD A BBQ PIT.
(Or ask for help, there's a lot of friendly people around here)
