DISCONTINUED [STOCK ROM/TWRP/ROOT/OC-UV] RCA 7' Voyager (RCT6773W22) MT8127

[TripFX]

DISCONTINUED - Left for research and archive purposes.



After much hardwork @codelover and I are pleased to release both stock rom as well as TWRP 2.8.6.0
for the 2 known variants v31 and v38. Please make sure you download and flash for your specific variant. Check faq if you do not know which variant you have.

REQUIRED FOR BOTH VARIANTS:
Windows XP/Vista/7/8/8.1/10TP 32bit or 64bit
SPFT (Windows Version) “linux version coming soon”
Correct Scatter File
Preloader Drivers (if you do not know how to install manually go here)
ADB
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
Make sure your tablet is completely switched off then connect it to your PC and the flashing process will commence immediately.
Once it's done, you'll see the tick sign below and that's all. Reboot your device and setup your device afresh.

Flashing TWRP:
Same as above except only check mark recovery and select “recovery_twrp2860_vXX.img” and nothing else then proceed.

How to ROOT:
*With stock recovery: Kingo

*With TWRP: SuperSu

DOWNLOADS:

(V31.0 USERS ONLY)
Pre-Rooted Stock ROM (scatter file included in zip and attached below)
TWRP 2.8.6.0 (scatter file included in zip and attached below)
EDIT: TOUCH FOR v31 TWRP IS MISALIGNED FIX IN PROGRESS. LINK REMOVED UNTIL THEN

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.

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:

                adb shell
	        su
                cat /proc/cmdline

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

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.

A correction to V31 in on its way
V38 has good reply on touch working well, small snag regarding to internal storage reported,,,

 

[leetree2001]

I backup and all buttons seem to respond to touch. I used twrp easy magic's unpack, repack to install it, thanks you guys, and girl's for you're hard work.

 

[nathanski]

gr8 t2o hear good results, thank you,,,

 

[leetree2001]

Great to hear good results, what file are you reporting success with, if I may ask,,,
I stay on my tablet like most of my time when I'm not working or ect,ect when I stop using it as heavily I am going to install twrp I guess, just haven't made time as the tablet is basically my main device

Twrp 2.8.6 v38,the only problem I found is internal sdcard not showing up in file manager. But external sdcard does,

 

[nathanski]

twrp. installer.exe http://forum.xda-developers.com/devdb/project/dl/?id=10082,, its a option

Note: Watch your tablet as you're doing this. You may have to grant su permissions on the tablet after executing the "su" command in adb.

I can't say as to why but you do need the self education one can learn about how to use spflash tool,, seeing as that's the way that I know that's the first info I could offer ,,, you should get your version information first, then download your ROM because the scatter file that had reports of best results are in the full firmware, and you then need to know that the reset button will bring up a driver install but it happens fast to catch this you need the device manager in windows open, plug the rct in then press reset with a tothpick or other small pin ect,, the device shows up with a sound chimes on windows, right click the new device in the USB group and install using the hosted driver,,, now to the spflash tool its self load the scatter in the full ROM related to the vershion you have and then only check recovery,,, and find the twrp.IMG in you downloads and use only the download option in the spflashtools,, and click download then Right after hit reset on the back of the tablet,,, it can be done ,,,, even for the new people wanting to learn,,, regarding the twrp,installer.exe I linked to, I have no knowledge it was only reported to be a full success by another user before you so I wanted to offer a fast way for others to find it ,, so I linked to the .exe,,, and lastly ON MY TABLET I HAVE TO BE ON A CHARGER TO LAUNCH RECOVERY AT BOOT USING VOLUME KEY,..and you can download a root reboot apk that will boot from inside android directly into recovery,, maybe I helped,,,, p.s. another great thing the full ROM offers is the original OEM recovery.. Pleas do try to learn. As always i do wish every one the best
