please excuse me as this may have been covered.... and i am pretty new to rooting any droid device! so this would be my first attempt at doing so... i am tech savvy, but not one person can know everything. my base is technical hardware/software problems in the pc and game console worlds.

I have had this viking pro for a couple years now, i even lurked in the old thread!

so i started off using Kingo root, had problems.... i did figure out how to root after a bit though... so now im stuck on changing it to super su? i tried to run the su script, for i have fallin into many errors with said script. the youtube video is down as well.....

i stuck the folder on the root of the internal drive with all four files inside still... i even tried to install the apk file and then trying to run it again to no avail ! same errors... every line has an error even when i give the script/terminal escalated permissions.

i do understand that this root is a bit harder than most, but i would still like to learn the process in doing so.

can i make a backup of the stock rom? i may want to revert all changes one day if at all possible. or is it too late at this point? can i rip out the stuff i dont want in the rom?

i may have more questions in the future..

details about my tablet

rca viking pro

build # RCT6303W87DK-Android5.0-V63-V1.12.0

if there is any other details needed please do ask, im not really sure what else to put up here as this is my first droid device.

Thank you for your time!
[Android General] NepoRood:
Flash SuperSu installer zip through custom recovery. Once installed, reboot and it should ask you if you want to remove other root and replace with Su...
[Android General] stonedhippiecomputerdude:
I have one I can let you use if you can do so with a broken screen(hdmi out works just fine, screen is just busted)

However I was hoping I wouldn't have to as I dont have much money and cannot really afford to give my stuff away so Ive been keeping a eye on this thread and doing occasional web searches but so far nothing, if you would be willing I can send you my m7 you would have to pay for shipping, if you root it you can keep it if you cannot root it or do not want it after you root it I would like it back, however, Id pay return shipping

Btw I know the risks but you seem to be a knowledgeable person on here and see this as low risk but if you brick it I realize this is a risk

Rereading this I feel it needs clarification, I would be asking for reimbursement of shipping costs or if you like you can send me the money by something like pay pal NOT the money upfront unless this is what you would rather do
[Android General] NepoRood:
I'd take you up on it if the screen wasn't busted, plus, with Android 8.1 being out, it's only a matter of time before RCA starts making tablets with Nougat...
[Android General] dazemc:
So, what is the x.10.xx firmware? Can I flash 9 or 12?
[Android General] NepoRood:
Depends on your build id, the firmware in the OP are NOT cross compatible. You have to flash 9 to 9 or 12 to 12, 10 doesn't' work
[Android General] Jadevinicole:
So, and this might be a stupid question, has anyone been able to find a working root method for the RCT6303W87M7 running Android 6.0? I haven't been on for a while and I've given up trying since the only viable search result that Google comes up with is this thread. I still can't get the bootloader to unlock since it won't let me make a selection using the volume buttons and I haven't found any other way to get them to work. Thanks in advance.
[Android General] NepoRood:
Doing some searching, I found This, looks to be the same guy/person we got our firmware from. See if he has the exact version of your firmware and if he does, download it. Then make sure it will flash and boot on your tablet.

Once you get that far, I'll need the recovery and boot images, then I can do some TWRP builds for you to test. If we can get a working recovery, you can get root.
[Android General] Jadevinicole:
Thanks, i'll let you know how far i get,

Root over windows?

Hey guys.

I am tech savvy but I think this root is a bit over my head. I have ordered the male to male cable, would anyone be willing to root this tablet for me over the web using remote desktop? I can pay with Venmo, PayPal or something but need to get this thing rooted so it is remotely useful.

Thanks so much, hope to hear from someone. ???
[Android General] c3p0u812:
http://www.panc.cc/m/info/e011193766395d08 <-- This is the exact version of the firmware. Does this help? How can I get the recovery and boot images?
[Android General] NepoRood:
Download and extract it, everything should be in the rar package. It should also be tested using the flash tool to make sure it boots up.
[Android General] endleesss:
Will this root method work for this model? RCT6303W87DKF C
[Android General] NepoRood:
If it's running Android 5.x, probably, newer versions of Android need to do something else (which has yet to be discovered AFAIK)
[Android General] Crazed Fool:
What firmware source would be best suited for my tablet?

Is there a difference between them?

I have build # RCT6303W87DK-ANDROID5.0-V63-V1.12.0

Are there any special notes that I should be aware of before I continue with root and recovery flash?
[Android General] SupaNegro:
My Viking Pro has a build number of 1.15.50 where can I find the root files for it?

Rooting the Viking Pro RCT6303W87M7

Question here from a novice (which will become obvious in a moment) -- My tablet is Viking Pro, Build No. RCT6303W87M7-ANDROID6.0-V06-V1.16.30-E05. I've read all the posts here about the difficulty in rooting the Viking Pros. I've never rooted a tablet, but would like to do so on mine for one reason -- while the tablet does a lot for $69, the lag associated with having 1GB RAM is noticeable. I've read about installing Roehsoft RAM Expander to add some RAM from the MicroSD card I've installed. Roehsoft RAM Expander requires rooting, which led me here.

I would be very grateful is anyone here can explain if and how my tablet can be rooted so I can add Roehsoft. As an additional question, if there is a way I can add RAM without rooting, I would love to hear that.

Thank you very much.

-- Eric

Can't install drivers

No matter what I do, I can't get the MTK drivers to install for my RCA Viking Pro. Mine is Build 1.12.20-B. It briefly sees there's something on USB but then any chance to get to a driver is gone in 2 seconds. I sure don't have 5 seconds to do anything. I have the male-to-male cable AND have it plugged in for charging. Ideas?
[Android General] NepoRood:
You can try the Auto Installer, get it Here
[Android General] RealSkier:
That didn't work. Drivers failed to install. I picked the Lollipop version for Windows 8 - 10.

---------- Post added at 02:00 PM ---------- Previous post was at 01:57 PM ----------

Didn't work. I tried the version for Lollipop Windows 10. Failed message from install package.
[Android General] bobl61:
Guys, there's no reason to root with kingroot. Copy SuperSU to your sdcard. After installing custom recovery, reboot phone by holding volume up and power button. After you see RCA logo, release power button but keep holding volume up until you enter recovery. Flash SuperSU via recovery. Wipe cache and reboot. Update SuperSU via Play Store. When it says binary needs to be updated, use recovery method. Voila! I always install busybox too :)
[Android General] CharlieSummers:
Since this is my first post in this thread, I will avoid any snarky comments about the previous "Voila!" post.

Over the past few days, I have read over this entire thread. I am feeling a little bleary-eyed, and will admit I don't understand half of it, but I can learn. Before I get into anything, I will list the two RCA Viking Pro's I have sitting in my office (completely stock, never even connected to WiFi yet), and ask if comments about them are even being entertained here - there have been comments that anything other than RCT6303W87DK isn't welcomed here:

I haven't seen any prior reference in the thread to a x.21.x machine, but then I might easily have missed it. Anyway, would appreciate knowing if I may discuss these machines in this thread.
[Android General] NepoRood:
One of the problems with newer versions of Android is the ever increasing security. Also, lack of factory firmware for these RCA tablets make it a real pain to test, because you run the risk of bricking the device.

With the previous version of this device, which this thread was made for, we had backup firmware when things went wrong. I can't give you an honest number of how many times I bricked my Viking trying to build recovery.

Ours was found on a Chinese site, that no longer exists, so no help there. But there are others, if you can figure out how to navigate them, you might get lucky. You can start here, some quick digging, didn't yield your specific devices, but some are similar.

I need to get ready for work, good luck :good:
[Android General] NepoRood:
The RCA tab was the one I was talking about, lol. My Viking was hard bricked, wouldn't charge or anything, the above procedure fixed it
[Android General] nannycrick:
Thanks for that tidbit about the buttons on the RCA. I'll try that next. Downloaded the "potentials" that were posted. Taking care of family stuff so I'm still away from my PC. I'll let you know as soon as I can try to unbrick my 6203!

---------- Post added at 08:01 PM ---------- Previous post was at 07:41 PM ----------

Yes, the preloader is working but it doesn't disconnect. The preloaded stays on.
[Android General] smartmanvartan:
Ok you gotta flash the preloader alone... Try the first one. But there's a fifty fifty chance that it will wind up hard bricked after... But if it works, it will let you flash the store firmware the second time around...
[Android General] nannycrick:
Tried flashing just the preloader. Brom error 4032.
[Android General] smartmanvartan:
ok. there is still hope for your tablet. the thing is that it will only let you flash the preloader for your specific revision of the tablet. you mentioned that you had one with android 4.4.2 and bricked it. then sent it in to rca and they sent you one with android 4.4.4... that build prop version, its from the first one eh? you can force a preloader if you can find the button configurations. try holding volume down when you plug it in to the computer...
[Android General] nannycrick:
Okay. I'll try that! I've got that firmware downloaded. Haven't tried to flash it yet. I just got done updating my Lenovo Tab2 from KitKat to Lollipop, and then had to flash the updated version of Lollipop with patch fixes. SPFT worked without a hitch to do the flashing. I'll continue to try to get it running. The preloaded works, but doesn't connect then disconnect às it should. The COM port connection is correct. I may have to face that it's parts now!
[Android General] nannycrick:
OMG! The Surf 1000 firmware worked!!! And the rca6203 is running Lollipop! Smartmanvartan...

You Da Man! AWESOME!!!!
[Android General] smartmanvartan:
That's awesome! Glad you got it worked out.. That's funny cause I'm running the surf1001 firmware on mine. :)
[Android General] nannycrick:
Is there a version of twrp recovery that works with this?
[Android General] NepoRood:
I'm still working on that, it isn't looking good, lol. The CWM Non Touch for the Viking should work for you though, if you're running the Accent firmware, like we are, anyway.
[Android General] smartmanvartan:
She is running the accent firmware for the surf1000 not the surf1001. Did you try the twrp from your device thread? Flash it with spft. Should work from what I can tell.. Otherwise I'll see what I can do later today.
[Android General] nannycrick:
I have TWRP from the original version of KitKat for the 6203. That was the version that bricked my 6203...twice! I also have a TWRP recovery for Lenovo Tab2 running Lollipop 5.0.1 that was ported by Tzul. Don't know if it will work. I just got it running so I'm afraid to brick it again...and again....and again!

Third time's not "a charm!" LOL!

Remember...that Tab2 also has MTK8127 chips.
[Android General] smartmanvartan:
I assure you that using the proper scatter file, flashing the twrp from the kk firmware version will not brick your tablet. Use the scatter file from the surf1000 firmware... Take it out of the folder, load it into flash tool. Then on the recovery line on the right select the folder and the twrp and flash it. It should work.
[Android General] nannycrick:
Couldn't get the bootloader unlocked. Oh well..I decided to root it with Kingroot to debloat it. I'm giving it to my youngest son anyway. He likes to work on old cars. He can use it in the garage for parts hunting & wiring diagrams. Sitting at the local McDonalds doing app updates. Free Wifi is great!
[Android General] smartmanvartan:
In the bootloader section of this thread, there is a bootloader editing tool. should work for yours.
[Android General] nannycrick:
Tried it. Couldn't get it to run. Besides...now that I have working firmware, I can always return to unrooted stock, when my son is done with it. Not a deal breaker for me! I have two local folks I know with the same tablet that are bricked. I'm going to unbrick those for them. Thanks tons for giving me a working RCA tablet again! : D
[Android General] smartmanvartan:
No problem :) glad you got lollipop in it! That's always cool when you go from broken to awesome!
[Android General] nannycrick:
AMEN! It finally got my husband off my back about the purchase of the 6203 AND Lenovo Tab2 ! Whew! Argument fixed!
[Android General] born22:
is there any way i can get rid of the software volume up and down buttons?
[Android General] smartmanvartan:
Not at the moment... Not that I know of...
[Android General] CharlieSummers:
Security is a good thing, no question. But I paid for it, it's my device, and I should be given administrative access if I want. Any lawyer who wants to file a class action, I volunteer to be named party. ;)

Thanks for the pointer. Have to admit, I'm not exactly sure how to tell which firmware might be close to these, but I'll give it a go anyway.
[Android General] NepoRood:
For the Lollipop version, the ones we had, the middle number in the version string was key, example from your device:

RCT6303W87M7-ANDROID6.0-V21-V1.15.80

That's the magic number in yellow, the "V21" is just a different identifier of the same firmware, V1.15.80

Theoretically, any firmware with the "15" would work (like the link I previously posted), as long as it's same android model (RCT6303W87M7 in your case). Unfortunately, there's only one way to find out and that's to flash it and see if you have boot.

If it doesn't boot, you'll likely end up with a brick and have to download and flash more firmware until you find one that works. A guy in our group did this, his Viking was bricked for like 3 months before a viable firmware was found. Then, as you can see, we discovered more.

Although, one way to test would be to just flash recovery, see if that works. That would trim the possibility of bricking quite a bit, you just might not have a working recovery :p
[Android General] CharlieSummers:
Yes, I know the black one is a x.15.x; the "V21" in it was a wild but interesting coincidence. If you scroll that code block down a little to look at the purple one, however, you'll see:

RCT6303W87M7-ANDROID6.0-V11-V1.21.0-R00

That's x.21.x so far as I can tell, screendump from the tablet included here, and I don't think that version was mentioned anywhere in the thread.

If I had a recovery that would work for the black x.15.x, I could get everything that I want - I'm only interested in rooting, not replacing stock firmware. However, and again this is my reading through the entire thread with the possibility of missing things, no one found a recovery that would work on the x.15.x.

And then there's the purple one, which I am terrified to even look at crosswise let alone poke recoveries in there!
[Android General] NepoRood:
By "recovery" I was referring to stock recovery, that would come in the firmware you download. If you flash it and can still boot recovery, you likely have a working firmware. If you have a working firmware, I can try to build TWRP for you, or at the least port the CWM recovery.

If the device has working ADB, you can try pulling the boot image and patching it with Magisk, then flash it back to the device...

PS, I went the x15x example because it was the first one in your list and there were some possible downloads on the site I linked. I didn't search for the x21x
[Android General] CharlieSummers:
This is where I mention again how far y'all are ahead of me. Didn't even know what Magisk was until a few moments ago.

So after dinner this evening, I will, using the black tablet, 1) check to see if USB actually works on the device (I have a USB kit with M-M cables), and 2) research how to pull boot.img assuming it does.

Thank you for the direction!
[Android General] CharlieSummers:
Apologies for the delay, we had some rain issues this past week. (And I'm old, slow, and easily distracted, but mostly the rain. ;)

I have yet to be able to connect via ADB - used adapter cable from a USB kit and can't get any connection, as described by others in this thread. I do want to test a few cables I have sitting in the basement, hopefully sometime today, but it isn't looking good.

The only ADB-over-WiFi APKs I have require root...I'll nose around and download some that don't, but IIRC flashing software isn't a great thing to try over WiFi, let alone under non-root.

Of course, since you guys are the experts, if there's some "Rosemary Woods-style" gyration I can perform to connect to ADB over USB, please advise. (And that reference certainly does betray my age, doesn't it?)
[Android General] NepoRood:
Don't apologize, lol, I'm all of the above too

I'm guessing you're on Winblows? ADB is a curse for these type of tablets, apparently. My Maven Pro connected to my Linux PC without issue, haven't tried the Viking since the wife took over it.

You could try to use the SPFT to do a readback and pull the firmware from your device. There's a guide here
[Android General] varunmagical:
I just bought this tablet and trying to rot it since 3 days. It came with Android 6. It seems it is not possible to root it. Please correct me if I am wrong .

It seems it was possible till android 5 version but now possible anymore. I should have checked it before buying I guess. Just assumed it is highly sold items so obviously methods to root are out there.

[Android General] NepoRood:
I bricked mine a dozen times and more....

Make sure the device is powered off, not booted to recovery.

Load up the firmware in the flash tool and select Preloader only.

Plug in the large USB cable to the device and your PC, plug the small cable into the device.

Click the download button.

Now the "tricky part":

Press and

hold

, Power, Volume up and Volume down at the same time.

Plug in the large end of the small cable to the PC, then press and

hold

the reset button on the back of the device.

Hold ALL 4 buttons down until the preloader flash completes.

It may take a couple tries, or more. Once that's done, uncheck the preloader and select the rest of the firmware files, unplug the large end of the small cable from the PC.

Click the download button and plug back in the large end of the small cable into the PC. This time without holding down the buttons.

The firmware should flash and your device should boot again.
