[ROOT][FIRMWARE][BOOTLOADER][RECOVERY] RCA Viking Pro (RCT6303W87DK) One Stop Shop!

I am not responsible for anything that happens in your life. Including what happens as result of following steps in this thread.
Hello all. After a long journey here, we figured a new thread would be in order for new comers not to have to read through fifty pages of information. Here you will find firmware to fix or update your Viking Pro. You will also find root methods, bootloader unlock and custom recoveries for this tablet. Lets start with ROOT...
Method 1: Kingroot. Kingroot works on this device. you can find it here. It's pretty straight forward, just download and install the apk and root.
Method 1.5: SuperSu. Kingroot works but it's not the best root out there. once you have root, follow the instructions here and Kingroot will be replaced with SuperSu.
Method 2: Su flash-able ZIP. This method requires you to follow steps in posts No. 3 and 4. Once you have custom recovery installed, You can flash This.
This method is a bit redundant. However, it does allow you to make a completely stock unooted backup of your rom before making any changes.
Check out posts 2, 3, 4 & 5 for the good stuff.
I'm gonna go ahead and thank everyone responsible and If I forgot to mention you, please don't hesitate to tell me and I will correct the situation:
@Bogram (Edited the bootloader so it could be unlocked on x.12.x versions)
@Jacube22 (Duplicated the method from Bogram to make the bootloader on x.9.x versions unlockable)
@vampirefo (Compiled a compatible CWM recovery for us)
@ewilley2008 (Found most of the firmware)

FIRMWARE
There are two main branches of development for this tablet. It is very important to know which one you have because they are incompatible with each other. I personally bricked my first one with firmware from a x.9.x while mine is x.12.x. How do you check? Simple. In your build number, you can find it in "About tablet" in Settings or in the text at the top of the recovery screen. It's at the end of the number and it will look like 1.12.30, 10.12.20, 2.12.20, 1.9.1, 1.9.5, 10.9.1...etc The number in the middle is the important one.
Steps(Windows): 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.
2- Plug your tablet in as such: turn off the tablet. Plug a male to male USB wire from the computer to the USB port on the tablet. now plug the power wire into the tablet. 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". Now navigate to the driver folder, select the "CDC" folder and click on "OK" the "Next". The driver should install at this point. Once that is done, unplug the power cable from 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. You will see the firmware get loaded and a checksum check.
5- Once that is done, uncheck the preloader from the list and click on the download button.
6- Plug the power cable into your tablet. At this point the sp flash tool will load the firmware into 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- Press the reset button and turn it on. Done!

Bootloader
So the bootloader on this tablet is locked. To unlock the bootloader, in a perfect world, you would usually boot the tablet in fastboot and type the command "fastboot oem unlock" and then follow the instructions on the screen. However RCA did not code in the volume keys in fastboot mode so it was impossible to unlock the bootloader that way. So our friend Bogram edited the bootloader and now the volume keys are not needed. What swell guy eh?
Unlocking your phone’s bootloader completely wipes (formats) your Android phone’s internal memory including applications, contacts, SMS and MMS messages etc.
So what you need is a scatter file like this one and a patched bootloader like these: x.12.x or x.9.x .
You will also need ADB & Fastboot and the drivers.
1- Just like in the FIRMWARE section, install drivers and SP Flash Tools.
2- Open SP Flash Tools and load the scatter file and in the line where you see "uboot" on the right click in the blank field and a window will pop up. select the patched bootloader. Make sure it checked and click on the "Download" button.
3- Now plug the male to male USB cable and then plug in the power. SP flash tool will flash the bootloader and then show you a nice little green check mark.
4- At this point you need to unpack the adb folder from the RAR file and place it in the root of you hard drive(C: ) then open a command prompt and nvigate to you adb folder (cd c:\adb) and leave it there for just a second.
5- On your tablet unplug the power wire, hit the reset button in the back and boot it into recovery mode by pressing and holding the volume up and power buttons together until the RCA splash screen comes up then release them.
6- In recovery, use the volume keys to navigate to "reboot to bootloader" and use the power button to select.
7- At this point your tablet will be in fastboot and your computer should detect it and install the driver. If not, the driver is in the "Android" folder in the driver files you extracted.
8- In your command prompt you left opened earlier, type "fastboot oem unlock".
9-Your tablet will do some magic, summon a demon, banish it to the depths of hell, reboot a couple of times and then it will have a unlocked bootloader.
10- Done. now you ca move on the next post and flash recovery.
Bogram also created a tool that patches the bootloader automatically should you have a different version we don't know about or what not...

RECOVERY
This section depends on a unlocked bootloader. If you did not unlock your bootloader in the previous post, do so before continuing to this one.
So what you need is a scatter file like this one and a recovery.
CWM + Carliv compiled by vampirefo: (x.9.x)Clockworkmod recovery (x.12.x)Clockworkmod recovery
TWRP V3.00 compiled by Neporood: (x.9.x)TWRP V3.00 recovery (x.12.x)TWRP V3.00 recovery(Coming soon)
- Open SP Flash tool and select the scatter file.
- in the recovery line, on the right side in the blank field, click and select your downloaded recovery.
- Click on the download button.
- Make sure your tablet is off, plug the USB cable first and then the power cable.
- SP Flash tool will flash the recovery and show you a lovely green check mark.
- Once that is done your recovery will be flashed.
** The stock system has a file in the system folder called "recovery-from-boot.p". this file flashes stock recovery randomly at boot so with a rooted system, navigate to the folder with a root capable explorer and delete the file so that your new recovery stays there.
** When rebooting from recovery, cwm will tell you to fix root. Don't. Select no every time.
For thos of you who want a file explorer in recovery, You can download this Aroma installer flashable
It's a nice tool to have...

ROMS
Not yet but soon.....

I'd swear I've seen all this somewhere before... lol
Good job, brother!

Now , let the roms...begin.....

woot ... just in time as I brought my Viking Pro home from Wallyworld Saturday night.
Any thoughts on ADB? I couldn't make it all the way through the other thread and eventually just gave up.... ended up figuring out Kingroot on my own and then just enabled ADB over wifi. Would much rather have a wired ADB solution as moving an APK (I'm a developer, duh) over wifi can be somewhat s-l-o-w.

Any plans to make a thread like this for the RCA Maven Pro (RCT6213W87DK)? It'd be really swell.
EDIT: Actually, with those sources you posted, I actually might be able to do this on my own.

I've got a Maven, and I've already done the porting. I'll be posting a guide tomorrow morning sometime. For now, I've sent you a PM with links to the firmware. Check your firmware version, mine is V36-1.9.21 (as long as you have the "9", you should be ok) The zip file has everything in it, preloader, scatter, custom recovery, etc...
Maven Guide is up, find it here

I can't get the port(s) to light up under OSX. I've tried a couple build.prop changes, plugging in micro usb, usb type a, power connector, and various combinations but none of them appear to trigger registration of a usb device of any kind on the host machine.
I can't even get simple stuff like MTP to work.

Time is my issue but I'm looking at two things. there is a firmware package i found on the Chinese server for a tablet with the model number rct6603w47dk with the same board as the viking pro but with a 8163 instead of the 8127. i think its doable to port over to our tablet. it is android 6. also the maven pro(rct6213w87dk) which is really close to our tablet with the same board but a larger screen, has adb working on it...

You should be getting a reaction through the micro usb port... on windows it shows up as a malfunctioning device.

i get nothing when sniffing the USB bus on my MBP.

I does the same thing on Ubuntu 14.04, absolutely nothing shows with "lsusb" in the terminal, unless it's in fastboot mode. You can use fastboot to flash the device, if you don't have access to a Windows machine...

I tested the new 1.9.3 firmware on my tablet... and it just shows a black screen.
DO NOT FLASH IT. it didn't work

What's the difference between sp_drive_v2.0_finally & mtk_sp_drivers_v2.0
Because I got the sp_drive install but having a problem with the mtk_sp , it keep popping up as incompatible software.... I'm stuck on the boot loader section

What version of Windows are you running..the difference is the drivers are signed or unsigned.. This matters more on newer versions of Windows.

Vonino Jax X - flashing stock rom with instructions [Tested]

This is not a question but instructions on how to flash this very rare phone (I could not find anything about this anywhere)
basically the company who makes it actually provides all the files but they are not easy to find
if you know what to do.. the ftp is located here
ftp://ftp.vonino.org/public/Firmware/
if you don't, continue on..
1. download the USB drivers and install them (sounds easier than it actually is)
here are some instructions from the company but they are in romanian

but I can break it down for you (if you are on windows 10 x64 like): (info from here with some changes)
1.1 disable Windows 10 - 64 bit driver signature enforcement
- Click on Start then on Settings
- Click on Update & security then in the left pane click on Recovery
- Under Advanced startup click on Restart now button (you might wanna write the next parts on paper)
- Click on Troubleshoot then on Advanced options
- Click on Startup Settings then on Restart button
- The computer will restart with the Startup Settings screen
- To disable the driver signature enforcement until next restart press on number key 7 or F7 on your keyboard.
- wait for windows to start ..
1.2 install MTK VCOM USB Drivers
(I actually did this two times and will explain the two methods)
- download drivers from here https://www.androidfilehost.com/?fid=24269982087012126 and extract to a folder (1)
- download drivers from here http://ftp.vonino.org/public/Firmware/01_GENERAL_DRIVERS_FOR_MTK/ (Driver_Auto_Installer_v1.1228.00.rar) and extract to a folder (2)
ALTERNATIVELY to this next section you can just right click the inf file and click install.
- go to device manager (in w10 u can right click the start button and select it from the list)
- here select your computer THEN go to Action -> add legacy hardware
- On the Welcome to the Add hardware Wizard window click on Next button
- Select Install the hardware that I manually select from a list (Advanced) and then click on Next button
- Click on Show All Devices then on Next button
- In the Add Hardware window click on Have Disk… button
- In the Install From Disk windows click on Browse… button
- In the next window – Locate file – browse for the folder (1) that you have extracted on the desktop at the beginning
- Select the version of the driver according to your Windows 10 version – for 64 its "Windows 10 x64 MTK USB Drivers" (for 32 its Windows 10 x86 MTK USB Drivers)
- Click the OK button to load the driver
- From the list of drivers select MTK USB Port and click on Next button
- If a red warning window will open, click on Install this driver software anyway
- Now remove the device that was installed but leave the drivers in the operating system. (To do that in the Device Manager window expand Ports (COM & LPT) section, Right-click and click Uninstall on the MTK USB Port, making sure in the Confirm Device Uninstall window, that the box Delete the driver software for this device is empty)
- do this again for the other driver
- just this time browse for this folder Driver_Auto_Installer\SmartPhoneDriver\x64\Infs\ (or x86...)
- and select this file: usbvcom.inf
- then pick the first item.. DA USB VCOM Port
2. Download SP-Flash-Tool from ftp://ftp.vonino.org/public/Firmware/02_GENERAL_FLASH_KIT/SP-Flash-Tool-v5.1532.00.rar or http://tehnotone.com/download-sp-flash-tool-v3-v5-latest-versions/ and extract it
3. Download the latest stock ROM here
http://ftp.vonino.org/public/Firmware/Vonino_Smartphones/Jax_X/
- extract the contents of the zip file to a folder !
4. Flash the phone (https://androidmtk.com/flash-stock-rom-using-smart-phone-flash-tool)
so in order to do the actual flash
- turn off the phone and remove the battery (dont attach any cables to it yet)
- open flash_tool.exe
- select Firmware upgrade from the dropdown
- browse for the Download Agent and select the MTK_AllInOne_DA.bin in the SP-Flash-Tool folder.
- click on the Scatter-loading button and browse for the MT6580_Android_scatter.txt file located in the rom folder you extracted.
- click on the Download button
- connect the phone to the computer using the USB cable (with or without battery but it should be turned off)
- press the volume up and volume down buttons at the same time (I think this is optional, just wait and see if the download starts if not press the buttons)
- leave it to upload the new firmware, once its done a green button will appear
- close the flash tool and disconnect the cable
- start the phone and wait (for me it took about 7 minutes) but this will only happen the first time
hope this helps
ps: related to how I got into this predicament, if you gonna root your phone using Kingroot (it will work) DONT use SuperSuMe to try to remove Kingroot but keep root just coz the adds in the lock screen annoy you, it will boot loop your phone..
ps2: I hope Kingroot and all the other chineseroot ***** go bankrupt .. trying to brick my phone ..

Thank you so much. It wasnt easy but it worked perfect. Thank you for very detailed instructions it helped a lot. God bless you!

Can this phone support Android 7? I saw on the chinese shops that android 7 is rolling out on some MTK devices with 1GB of RAM?

Why do you have to disconnect the battery? What if the battery's drained, should you still disconnect it?
(I'd rather let the back cover on 'cause I've already damaged a tab removing it)
