Hey guys, I somehow managed to really mess up my v31 tablet. Here's my best explanation of what's happening:

I rooted and attempted to flash the TWRP recovery image from Android terminal since I wasn't near a computer using flash_image tool. After that when I rebooted the 1st time the initial boot logo came up and then the tablet went black.

After getting back home and having time to work on it, I started using the SP Flash Tool and the stock images found in this thread. I managed to get the recovery working again with both the stock and TWRP recovery images. The system is the issue. When I flash the system to the tablet I am able to run once before a reboot or reset. On reboot the system disappears but I can still get to recovery.

Last night I started trying to install apps when I got the system up and while they were all downloading they didn't seem to install correctly since they never showed up in the app drawer.

I"m guessing maybe there's some issue with a partition or permissions, but I don't want to mess with it without knowing how everything should be.

I have both cleared and reformatted the data and cache partitions from recovery and from SP Flash Tool. Do I just need an image of a blank data and cache partition to completely restore everything back to stock?

Any thoughts or suggestions would be appreciated. Thanks!
[General Topics] synius:
you could've just used spft to flash v31 twrp recovery with provided scatter

You may need to full format + download, the entire v31 stock rom

That means flashing the nan with stock not download as in attaining files

Then download v31 twrp recovery and spft with provided scatter

This time download only in spft with only recovery checked

If problem persist please inquire about help

THE V31 DOES NOT NEED ANY SPECIAL ATTENTION FOR RECOVERY

Should be able to flash recovery relatively easyly

V38 and V28 does needs special attention because addresses within device are incorrect

If you need assistance with flashing I can provide you with that

If u prefer i can teamviewer and or teamspeak3 and assist you

Nevermind. I flashed this twice with v31 and after reboot, my father was impatient and would turn it off during the first startup. After he did that each time he tried to turn it on it would just hang. But after reflashing again and him being patient, it loaded in a couple minutes, got to the RCA logo, then the welcome screen. Everything seems to be fine now.

One minute oddity, during setup of WiFi, the first item was some sort of "NVRAM error". But I just manually added the hidden Wifi connection and it worked fine.

Edit:

It seems like its having problems still. He was able to install some apps. But after shutting down and restarting the tablet, it freezes at the boot logo with the dog. I can get to recovery console every now and then. I followed the steps on the first page using Readback to determine to use v31 instead of v38.
[General Topics] synius:
I've been hard at work,

the initial v31 release is incorrectly scattered

Be patient with me because I'm testing it to fix my v31

Yes it boots after flash but the tablet itself. Uses 2 system 2 cache and 2 userdata one is a regular image that gets remounted on the second system partition as ubifs this second partition gets flashed with the original system image every boot,

because the scatter tells the device hey the ubifs is already mounted it boots once after shutdown it tries to copy the original system which is empty, so it writes the system empty and fails to boot a second time

The nvram error is the WiFi mac address it won't cause issues but it's basically scanning itself not knowing it's itself as it's non identifiable it's fixed by 2 solutions one from earlier in this forum or the other forum,or flashing the devices original nvram.img

I haven't givin up on development

So bear with me
[General Topics] vanderb:
Thanks.

When I did the readback, it didn't work with length 0x1000 (alignment error or something), so I determined from the scatter file to use something like 0x40000. It didn't mention ANDROID near the start so I assume it is v31. I tried the v38 and it wouldn't even start, so then tried the v31 again. But i also see that there are other versions. I still have the readback file.

Also, the SmartPhone Flash Tool mentions a Linux version. As Linux is my primary system (Debian Jessie), that would be much preferred over finding a computer with Windows 7. Where can I get the Linux version of SPFT?
[General Topics] synius:
Unfortunately dumchar_info doesnt supply info for mtd19 system mtd20 userdata mtd21 cache

/proc/mtd does provide sizes

Tried using mtkstudioRom

To calculate sizes to a make a different scatter with the extra 3 partitions I run into insufficient space

The problem I see with mounts

Is system gets mounted rw

Not ro

Rom toolbox doesnt work to remount system ro due to ubifs aspect

That permission causes system to get written too after boot

I've tried setting files read-only

Also didn't work

Hard to say with readback and I'm not gonna dice it. No experience

So the question is how do you flash the file as read only so it remains whole accoss reboots

I noticed USB debugging is not working at all

The only mount that's ro is rootfs why is that? Is it because of protect_f

Also mtdinfo states for partitions in question write true

One time programming doesnt work its not supported parameters page in spft.

As is I give up not sure how to make it work

[General Topics] InuyashaITB:
Thanks, I tried with an older TWRP and it flashed successfully, however I cannot get the tablet to boot into recovery mode? (i was never able to, even before attempting to flash)

Mine has an actual Reset button on the back of the device, which when pressed just forcibly restarts the devices

Edit: I have tried adb reboot recovery

And I have also tried Volume up + Power

What happens is that it goes to a black screen for a half of a second and then just restarts the tablet into the regular ROM

i'm in need of help like big time

i forgot to backup nvram img and i did a full format

my motherboards says ver.05 idk if this helps or not, im on v31 if you need another tester

i've wrapped my head arounf fixing my tablet for three days now ready every single one of these posts, i can pull files and grab whatever part of the nand you need

stuck with a nvram error = 0x10, i'm sure it has to do with the ubifs and what was mentioned about the dual partions, and how the tablet will only boot once after flash. any clues

i was almost thinking of going to walmart and switching boards
[General Topics] synius:
Contact rca they will replace tablet if u describe software defect

Other then that don't mess these up

Nvram error is a WiFi mac address identifier that's missing

The scatter is technically wrong at the same time is close to being correct

It flashes properly without the readonly attribute, but system writes to another partition every boot which causes the device to fail after restart

Honestly. It is possible I just don't have time
[General Topics] cbentrott:
if i could some how write the 3 ubi partitions would it work, one for system, cache and userdata to match the normal ones created by the scatter.

the ubi partitions are not created through the scatter are they,

i watched this video about a china tab factory and she just had a cup of microsd cards, that were pre loaded with the rom or something, she was flashing like thirty at a time.

on the tablet, green progress bar across the screen. which brings me to my point, who owns rca now, how would one accuire original roms from them, have you ask. very intrested in how the the partitions sytem works here, my old phone was ext4 and i've read a small bit on yaffs2.

Seriously need help with then same ta tablet with Android 5.0

This won't work for the Android 5.0 LP model right? I can't find anything explaining how to root for some reason. Is there a way without a computer? Kingo didn't work unfortunately and just figured out how to replace the KingSu or whatever to good ole SuperSu. Had many issues with root privileges on apps like Lucky Patcher and stuff. Wouldn't or couldn't recognize busy box and patches just seemed sloppy I suppose ya could say. DID manage root on a few devices when couldn't find anything else that would root. I'm so over android 5.0 though.... Just got a S5 through Verizon that had the "life sentence" update, or what I like to call it. Was unaware of the issue when I bought it and got out from under it quick. This 60 dollar RCA Quadcore runs better or at least just good as it did. All Verizons bloat BS ya can't even disable or a bunch ya can't anyways.

But sorry got off subject and just need to know the proper method to SAFELY root this tablet. Same model number with a B at the end, and 5.0

Or even a way to downgrade to KitKat if possible? Just any help would be awesome.

Had the RCA pro 10 and bought some junky generic SD card and somehow put it in bootloop. Still haven't figured out a way to get it to boot up. Tried factory data reset and cleaning the cache from the recovery menu. If anyone happens to know anything on these too would be SOO awesome. I have looked for a few months for a way to fix it with no luck yet..

Not sure what Email is associated with my XDA account, so gonna leave mine here just in case.

j.Heath.boyles@gmail.com

---------- Post added at 05:52 AM ---------- Previous post was at 05:35 AM ----------

From the research I've done, seems the KitKat version is pretty easy to root like most of RCA's devices. Is there a way to flash 4.4.2 with Flashify possibly? Ive watched a method on how to even root directly with a terminal emulator on some RCA tablet but could've been a much older model.

Oh and what's up with the boot loaders on both the Voyager II with 5.0 and there pro 10 with 4.2.2 I think. I think Jellybean was my favorite Android version to date. Just if anyone can fill me in because I'm just runnin in circles lookin for info on both models

RTC6773W22B Model also

I am wanting the objects and scatter file also for the W22B model.

Flashing the objects listed here only results in the W22B tablet being disabled and unable to respond to anything other then seeing flash objects coming down the cable again. If they are not for the W22B it just sits and issues DRAM errors back to the Flashtool.

Ive been keeping mine on the charger for now as I try to locate the proper files. RCA / Alco Electronics so far has not even responded to any Support requests Ive made. If their support philosophy is to have customers just go buy another RCA tablet because of the low price they sell them for.....THATS never gonna happen. If Im not able to reflash my W22B, Ill be obtaining a Lenovo Tablet in the future. Id rather pay the higher price for a fully supported tablet then a low price for one that wont even respond to Support Requests. If anyone comes across the flash objects for the W22B Contact me. Its a shame to have fully working hardware sitting idle due to some software issue.
