[Android General] NepoRood:
SPECIAL KNO'DIS

: This Guide has been changed to refelct proper installation for both types of Maven Pro tablets, be Sure to follow the appropriate guide.

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. This guide doesn't cover installation of ether of those. If you're looking for the guide to the Viking Pro (RCT6303W87DK), go here.

KNO'DIS

: I, OR ANYONE ELSE AT XDA, WILL NOT BE HELD RESPONSIBLE FOR "BRICKING" YOUR TABLET!! IF YOU MANAGE TO MAKE A BRICK, DUE TO YOUR "FUN-DA-MENTAL" INABILITY TO READ, GO BUILD A BBQ PIT WITH IT!!​

(Or ask for help, there's a lot of friendly people around here)​

So, without further ado, lets get started. First, you'll need to know which version of firmware your device is running, this can be found in 2 different ways. From a running device go to: Settings/About tablet and look at the Build number. Or you can boot into stock recovery and the firmware version will be at the top left of the screen.

You should see something like the following, and note the 2nd number after the 2nd "V":

RCT6213W87DK-ANDROID5.0-V37-V1.9.30 <-- This is x.9.x version of firmware

or

RCT6213W87DK-ANDROID5.0-V68-V1.12.30-B <-- This is x.12.x version of firmware

Now that you know which firmware you have, follow the approriate guide below. I've broken this post into 2 different sections, as each tablet is just a little bit different.

About the Bootloader

​

This applies to both versions of firmware and tablet users. Turns out, the booloader doesn't have to be unlocked in order to install a custom recovery or root the device. So there's really no reason to unlock it, and I have removed that portion of this guide.

Installing MTK Preloader Signed Drivers

​

Drivers located Here

x.9.x Versions

Steps (Windows 8/8.1/10)

: For step 2 you will have less than five seconds. Preloader mode is only active for a few seconds. So read first!

1- Extract the drivers to the Desktop 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. For me, it showed up under "Other devices" and read MT65XX.

3- Select "update driver software" then select "browse my computer for driver software" (make sure "Include subfolders" is selected.

4- Click "Browse..." and navigate to where you extracted the driver zip. You "should" be at the following path: Desktop/MTK Preloader Signed Drivers

5- 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).

x.12.x Versions

(Requires Full size Male-to-Male USB Cable)

Steps (Windows 8/8.1/10)

: For step 2 you will have less than five seconds. Preloader mode is only active for a few seconds. So read first!

1- Extract the drivers to the Desktop 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 full size USB cable to both the tablet and the PC.

3- Plug the micro USB into the tablet, the other to another USB port on the PC, now very quickly in the device manager locate the new device and right click on it. For me, it showed up under "Other devices" and read MT65XX.

4- Select "update driver software" then select "browse my computer for driver software" (make sure "Include subfolders" is selected.

5- Click "Browse..." and navigate to where you extracted the driver zip. You "should" be at the following path: Desktop/MTK Preloader Signed Drivers

6- Click on "OK" then "Next". The driver should install at this point. Once that is done, unplug both USB cables from the PC (I find it easier to just keep them in the tablet).

Installing TWRP

​

Firmware/TWRP Downloads

Maven x.9.x (Currently Contains: V37-1.9.30 and TWRP)

Maven x.12.x (Currently Contains: V63-V1.12.0-20150802 and V66-1.12.20-B-20150831 Firmware and TWRP)

Special Thanks to: [MENTION=6711317]ShadowCX11[/MENTION] for testing for me.

Be sure you are using the appropriate TWRP for your version of firmware, and do the following:

1- Extract the firmware and the SP Flash Tool to your desktop.

2- Start the SP Flash Tool, and where it says "scatter file loading" click and navigate to the folder where you have the firmware and load the scatter file (depending on device, it could be in the "Images" folder).

3- Once that is done, uncheck everything, and select "recovery" only, from the list, navigate to the TWRP image file and click "Open", then click on the download button.

4- Plug the USB cable(s)* back into your PC. At this point the flash tool will load the recovery to the tablet. DO NOT UNPLUG ANYTHING UNTIL THE FLASH TOOL SHOWS YOU A GREEN CHECK MARK TO INDICATE THAT IT IS DONE, OR YOUR TABLET COULD BE HARD BRICKED AND IRREPARABLE.

5- After you get your check mark, unplug and boot into recovery, hold the Volume + and Power button. When splash screen comes up (the 2 dogs) release the power button.

6- Welcome to TWRP

*Remember, x.12.x requires 2 USB cables to work

ROOT

​

You can get root by flashing the latest SuperSu zip file located here, be sure to download the flashable zip.

Otherwise, for root, you can use the KingRoot app located here, (get the apk, or "Download for Android") and if you don't want a Chinesse Super User app, you can replace it with the ChainFire SuperSu by going here.

NOTE:

This method of replacing KingRoot with SuperSu no longer works properly, and results in a

bricked

device.
