Do you have UEFI BIOS or Legacy? Also, you should take a look at EasyBCD for dual-booting, that's what I use...

Here's the guide

As I said, it's based on Ubuntu 14.04, but, the terminal commands should be about the same for any Ubuntu/Debian distro

hey I found a weird development version of the v66 firmware for the maven pro. it has more content and the boot and recovery images are included unpacked... and it has an ota.. uploading so you can check it out.

I took the firmware for the maven pro and tweaked it to run on our tablet. it's pretty flawless. I was trying to see if I could get adb on the Viking but unfortunately the lack of usb connection on the viking must be a hardware bug because i get the same unknown device as if i was running the Viking firmware. The two tablets are very similar, I barely had to do anything... repacked the boot image and tweaked the build.pro to rotate the screen and it just booted up as if if was meant to be. no issue with the resolution either. Anyways... completely useless but i thought i would report the experience. :)

Maven Pro 2.12 v66(the boot images came unpacked on the side): https://drive.google.com/file/d/0Bz4bOoJ_E5XzQzh3Z1RmNUk2VTg/view?usp=sharing
[Android General] NepoRood:
I'm guessing the recovery didn't rotate though, right? I think it's kernel related, but have no proof, only speculation. I'll dl and look at the firmware you put up. Thanks
[Android General] smartmanvartan:
It was just for porting purposes..I didn't try the recovery... yet....

@NepoRood

Want to try this on your Maven Pro and tell me if you still have adb...

https://drive.google.com/file/d/0Bz4bOoJ_E5XzTDZVdlZaMnJMMDg/view?usp=sharing

also if everything is following the right orientation and if you press volume down all the way if it goes into some wierd vibration mode... also, the screens between the v9 and the v12 of the maven follow the same rotation so the recovery should work with a simple kernel swap.
[Android General] NepoRood:
No problem, will be after work though, I'll get the download started before I leave. Also, I'm zipping everything up that was made from the CM build, it made a lot of stuff, but didn't put it in the zip or img files for some reason, but it's there. It's on a different PC, so I had to use 7zip, I'll pm you a link after I get it uploaded and you can look it over.
[Android General] smartmanvartan:
Cool. I got this one too if you want to see it. it's the frankenfirmware i made from the maven firmware for the viking x.12.x...

Neither one of the firmwares worked right :confused:

Surf on the Maven

:

1) Still had the dogs...

2) Screen did a funky little flash, then Accent logo in portrait

3) Stuck at this point (20 min or so), reset started the process all over (semi-bootloop?)

4) Had to re-flash stock, and restore backup

Mavenstien on the Viking

:

1) I like the Accent logo, so I don't flash the logo anymore :p

2) Neat that it said "Maven Pro" instead of "Viking Pro"

3) Screen Rotation was off, holding portrait it went landscape, and vice versa (always sideways from point of view)

4) Couldn't select a language, it scrolled a bit crazy too, once it got off "English", I couldn't get it to go back. But, still couldn't use the arrow to make a choice

5) See #4 in first section
[Android General] smartmanvartan:
Oh shoot.. i gave you the wrong system image for the maven on viking.. as for the surf on maven, I'll see what i can do

This is the right setup to run the maven on the viking...

https://drive.google.com/file/d/0Bz4bOoJ_E5XzZXdCbFgyX1pVSHc/view?usp=sharing

as for the surf on the maven still looking at it, as for the logo, i can't put the accent one due to the differences in the resolution... we need to figure out how to crack these logo.bin open and edit them...
[Android General] NepoRood:
I can unpack them with a tool I have, but they are in RBG format, or something like that, and there's a lot of files. I ended up moving on to something else after a few "fruitless" searches to edit them. I'll open both, don't take long, zip it up and give you a link, if you want.

EDIT:

Unpacked Logos

Also, the last build file failed to upload...
[Android General] smartmanvartan:
yes please. i would love to see them unpacked
[Android General] NepoRood:
Here's the last line from the unpacking script:

Image #58 written to 'logo.bin-img[58].rgb565'

Resolution: unknown

So you need something that can edit rgb565 formatted images...

I found a converter..checking it out now

[MENTION=7237874]NepoRood[/MENTION]

Converter is not working out great.. gonna keep looking into this.. in the mean time, you want to try take two of the surf1001 firmware on the maven?

https://drive.google.com/file/d/0Bz4bOoJ_E5XzYzBqR1c0bEEyU28/view?usp=sharing
[Android General] NepoRood:
I got it downloaded, but can't flash it right now, the wife is using the tablet to crush some candy. I'll try to test before I go to the office later.

The few image tools I tried on linux didn't work out so well either, thought it might be better on Windows, but never got around to trying. Good luck, hopefully you'll come up with something.
[Android General] smartmanvartan:
You know I kind of like the black screen with no logo i get from putting the wrong resolution logo.bin...

also if you try the surf firmware for the maven and it gives you a perpetual boot again, try flashing the tee1 and 2 in spft from your usual maven firmware and see if that helps..

and theoretically you sould be able to use a newer .12 maven rom on your .9 maven tablet by swapping out the kernel only..

Got an award ceremony at the school, I'll give it a flash when we get back :)
[Android General] NepoRood:
I'm guessing here, it wasn't supposed to be a black screen, was it?

Cause, that's what I got...
[Android General] smartmanvartan:
That's to bad.. If you charge it while off, do you get regular charge animation?
[Android General] Jacube22:
Oh I forgot to tell you: The boot animation still zones out for a second, then the animation is oriented right, but it is in the wrong spot.

And the vibrate mode bug is STILL there. :(
[Android General] smartmanvartan:
Ok thanks. I'll try again tonight....
[Android General] Jacube22:
Also fun tidbit: I got the tablet to heat up to 71.4 degrees Celsius (according to CPU-Z) while charging and using an app :crying:

And apparently someone over at ALCO decided that cheap screens were OK.
[Android General] NepoRood:
Yes, charging animation is still there. Also, I don't know if you (or anyone else) has done this:

I decided yesterday, to go back to the V77 RCA firmware, just to compare it with the Surf1001. After I used my Franken'TWRP to re-install the apps, it said: Android is upgrading... and started "Optimizing my apps"
[Android General] smartmanvartan:
Charging animation is still there.. that's cool. that means the pack/unpack tool works well but when i edited the picture i must have messed up... well that's a functional black logo.bin the the maven then. :)

as the the optimization, yeah it's happen to me before... probably cache rebuilding...

---------- Post added at 05:43 PM ---------- Previous post was at 05:42 PM ----------

Did the screen mess up when it overheated?
[Android General] NepoRood:
First time it's happen'd to me, I still got a gazillion things to learn about Android (but, I know more now than I did 3 months ago ;))

New tab coming tomorrow, and I can't believe I feel like a 12 year old on Christmas Eve, lol. Worst part is, the UPS warehouse is just down the road, and that's where it's at, like RIGHT NOW!!, but they're not going to deliver it until tomorrow. They told me: "Sir, you can't pick up packages here, this is a distribution warehouse, your package will be delivered by 5pm on April 2nd".

:mad:

PS: MavenSurf still stuck at Accent logo (it also does that "zoning out" thing that Jacube mentioned...)
[Android General] Jacube22:
No. But I could feel the heat all the way through the screen. And the charger that comes with this thing gets EXTREMELY hot when plugged in. I switched it out with a charger from a older RCA tablet. And the battery apparently has the best thermal paste in existence, because it stayed at EXACTLY 25 degrees celsius.

And the problem with the screen was that dirt is ALWAYS getting behind it, pixels are going out, I can see the backlight in the center, and lots of other stuff.
[Android General] NepoRood:

Yes sir, I did. It's pretty freakin' sweet too, lol. Absolutely NO bloat-ware, "Developer Options" already on with debugging enabled, out of the box. ES File Explorer (ES3), for a file manager, is the only thing that seems to be "extra".

It's slightly bigger than the Viking, and slightly smaller than the Maven. It has a 10.6" display, and it looks Good!

[Android General] NepoRood:
A note on the X10: when I run the "DevCheck" app, it said the device was rooted (out of the box?) So, I installed the kingroot apk, and it failed to root, from what I read elsewhere, I thought it might. Then I downloaded kingo root for pc, and it successfully rooted in less than a minute (after "unrooting device" first??)

I got this thing off eBay for $93, pick one up if you get a chance, it blows these RCA tabs out of the water. I've already started building a device tree :)

PS, This tab ships with an unlocked bootloader (I asked the manufacturer before I purchased), they are also working on Android 6

[Android General] NepoRood:
I'm not giving up on the Viking, I like it too. I just wanted to pick up something that didn't have a MTK chip in it. Plus, Allwinner is mostly open source (especially the kernel), anything I learn about it, may apply to development for the Viking ;)

[Android General] NepoRood:
TWRP for Viking x.12.x

It looks better than the last one, some touch points are still "off screen", but they're not that important (to me anyway)

Main menus (2 different screens, it is a "Watch" theme) works well, but, you need to use the "Home" or "Back" icons to back out of something. Also, the keyboard is a bit jacked, nothing I can do about that it seems. For the slider, touch just a little left of it to start it moving.

[Android General] Jaitsu:
So, uh, after reading through this thread I'm not quite sure what to think. Is there presently any known, working root method for a Viking Pro on V1.10.31? I'm doing this for a friend and I don't wanna **** up his tablet, hahah. King Root installs, but SuperSU can't update the binary and I'm a bit wary of that "SuperSU-Me" thing if it has a chance of bootlooping the thing when I have no backup.
[Android General] smartmanvartan:
All the info you need is here. What is the model number of the tablet? Where did your friend buy his tablet? That build number had not come up yet. Are you sure it's not 1.12.31?
[Android General] Jaitsu:
He took it back (I told him it's too risky for the time being, but I can tell him if I figure anything out) so I don't have it on hand at the moment, but the Build Number (I think) was rct6303w87dk-android5.0-v25-v1.10.31 according to my google history, if that's the number I should be looking for. I didn't check for updates, but I don't want to shoot myself in the foot if updating it makes it even harder to root.
[Android General] smartmanvartan:
Well i wouldn't go flashing anything but the root method in the thread I posted method 1 and 1.5 work on all the Viking pro tablets so far... But that build number has never come up. It's usually a 9 or a 12 in the middle.... Not a 10....
[Android General] Jaitsu:
The build numbers seem strangely out of order, but I notice all the builds you've got are V37 all the way up to V77 and I've got V25, so maybe what I have is a really ancient version? If you've got working methods for the latest versions, maybe I should update it.
[Android General] smartmanvartan:
This tablet does not update. You can update it yourself by flashing... but the update option in settings always says it's up to date. We have older version but again those are x.9.x...
[Android General] NepoRood:
Figures, lol. RCA and all their stupid "different versions" of the same tablet! Hope this gets worked out, shame we can't test on it
[Android General] NepoRood:
Well, the "pros" from the Cyanogen for MediaTek Devices thread appear to be a very tight group, and they don't want to share their info on building roms... I've sent/received a few PM's, and they are very vague when it comes to answering my questions.

For example: You're not getting a complete build because you need to add dependencies...

Really? It's not working because I'm missing something? Could you be more specific? (Apparently not...)

Anyway, I didn't notice any new posts, and thought I would let those interested know that I haven't forgotten this tab/project :D
[Android General] jerryvail35:
and thats why i suggested an ASOP or MIUI. this tablet is a pain in the a$$...
[Android General] NepoRood:
Amen, my friend, I gave it a shot with AOSP, no luck there either (probably more on me than anything, lol) Hopefully, we can come up with something soon...
[Android General] NepoRood:
Got the HDMI adapter yesterday, but can't seem to get it to work. Although the tablet said hdmi was connected, I couldn't get anything to show on my screen. I'll mess around with it some more after work and see what I can come up with
[Android General] smartmanvartan:
Ok I'll check out the other partitions and upload them. Then we can try a transplant of those. Find out where the hdmi settings are stored... Gotta work on taxes and the car today so probably this weekend...
[Android General] NepoRood:
Sounds good, I'll have company this weekend so my time may be limited, but I'll pop in from time to time.

On another note, building TWRP for this X10 is kicking my tale, lol. So, for a break, I've had an idea to work on the Viking again... :p
[Android General] PGHammer21:
Update while Rooting

Actually, you can update while rooted; you simply can't use stock update methods to do it.

You have to use either 3e (if available) or Flashfire (if your recovery is wonky, as mine was).

I had previously used KingoRoot + SuperSu to get root; the problem was, it left my recoveries unusable (both stock and 3e).

Not fun having no trustworthy backup OR recovery, and - to add insult to injury - being stuck on KitKat or older.

FlashFire was able to apply the update I had previously downloaded (but was unable to prior); the surprise was, it also fixed my 3e recovery (unexpected, to say the least).

Now i can do proper suspenders+belt backups and recoveries in FlashFire, and even apply updates two different ways (at minimum).

You can get the link to the current version of FlashFire (in the Play Store) from CHainfire's own project's page here @ XDA; even in "chicken" mode, it can save you a ton of grief.
[Android General] BenjiXBass:
Bricked?

I was unsure where to post this, so I figured the best place would be on one of the root threads.

Personally, I've rooted a couple of my own phones, but never had to track down a fix for a screwed up root, so I do have a little bit of experience.

I have my dad's friend's Viking Pro. Originally, he had a friend root it for him, and this friend made absolutely no backup at all. (I know, I said the same thing you're all thinking.) Supposedly, he got drunk and screwed with it, which is where our problem is. According to him, he deleted stuff and cant remember what he deleted. I have no idea what it was rooted with, or any of the information that was on it before it was rooted.

Underneath System Recovery, it says RCT6303W87-DK-Android5.0-V63-V1.12.20-B

It charges, and turns on, past the screen with the 2 dogs, to the white Viking Pro screen and stays there. It will connect to my windows 7 computer, but it says that it is an unrecognized device, and wont let me install the drivers. I can get into the recovery, but all of the options there are no help, except Root Integrity Checker, which says "Scanning ****" and then right at the end, everything starts saying "Error:System/" and continues to list a large amount of error messages, and then finally at the end, "Error: Found 633 New files, Error: Found 35 lost files, Error: Found 1 Modified file. System check fail."

Ive looked all week for a solution, even trying to flash a rom or 2, but nothing seems to be working at all. Can I possibly take a video of Root Integrity Check running, hunt down, and install all the missing/modified files as a .zip file? Is there hope for it, or is it just a fancy paperweight now?
