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.

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

Kingo was the only one I bothered trying to root it with. Kept saying that the device is not Supported but have rooted a few with this app though. Hell like I said, even found a means to switch KINGUSER with SuoperSu because I personally think kingo is kinda sloppy. But if ya can root with Kingo, and STILL be able to switch back to ole faithful, gets two thumbs up from me.
Oh yeah are runnin Kitkat?,,this ones on lollipop

Hi to all
I need stock rom for this tablet "rca RCT6773W22" with the MT8127 chip.
The tablet arrived with brick. Install the rom that is in the forum, it works, it loads and it works great, until it goes out or it restarts ... it eliminates the ROM alone, I have to flash again, again and again, every time I shut down or reboot the tablet.
Any suggestions thanks

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.

Has anyone been able to help you? I have gotten the tablet to last about fifteen minutes before it crashes and needs to be reflashed. If you have anything to help please respond, I have had this thing for years and just found this thread and was making some headway. Thanks in advance!

    A Brain

    Usage:
    For flashing either pre-rooted Rom and/or TWRP you will need spft+scatter file. It is imperative that you make sure that if you got a v31 you only uses v31 files not v38. Same for the v38 users only use v38 files. You have been warned.

    Flashing Rom:
    Make sure
    Run the file flash_tool.exe
    Click on scatter-loading and select your MT8127_Android_scatter_RCA_Vx.txt file
    Make sure all listed files are checked and if any isn't double click on it and select the appropriate file
    Leave settings as Download Only “if working tab Format All + Download "if wont boot' then hit the Download button

    NOTICE:
    Please keep thread clean and DO NOT ask things others have asked already as you will be ignored. If you do have a honest question and have a working knowledge of android. I would be glad to assist you the best I can. If you are noob and messed something up DO NOT ask for help. Meaning basics of knowing adb,logcat, installing drivers, and so forth. Sorry if you are a noob but please try to understand that things we may ask of your will require this and becomes too much of a slow down if we have to guide you thur everything.

    Guys, thanks for sharing the ROM dump, we are still analyzing the files, until then V38 users please don't use/flash any of the files.

    Meanwhile, can someone help me to test new twrp recovery for V31?
    Hopefully the touch works, otherwise someone will have run Magic TWRP to get correct configuration for me. (We will provide info later if needed)

    Thanks

    Faq:

    Question: How do I know which variant I have?
    Ansere:
    Method #1
    From a booted android, goto Settings > About > Build number
    You should see something like this.
    RCT6773W22-ANDROID4.4.2-3101-V38-V1.8.0

    Method #2 (Better & more accurate)
    For this your device must be rooted & already have USB Debugging Mode enabled.
    Make sure adb.exe has been installed on your system (computer).
    Execute the following adb command:

    Code:
                    adb shell
    	        su
                    cat /proc/cmdline
    MVeXrPS.png

    then search for ‘lcm’ text in the output:
    If lcm=cpt_clap070wp03xg_lvds < you need to use v31 files
    If lcm=1-lxjc070whm270_18a_rgb < you need to use v38 files

    Question: What if I dont remember which variant I have and can’t access adb?
    Ansere: If this is the case we will need to use SP Flash Tool to help identify your variant.
    Open SF Flash Tool, load V38 scatter and switch to ‘Read Back’ tab. Clear all then click Add,
    Click the new item & change the output file name from ROM_0 to ROM.txt,
    edit the readback address as below:
    Start Address: 0x9000000 / Length: 0x1000
    S1qYlvT.png

    Then press “Read back” button, now connect the tab while powered off.
    When it’s done, open the file with wordpad and check if you have “ANDROID” at the beginning of the file, if your answer is yes then you have V38, otherwise use V31.

    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
