iView 756TPC and Unofficial CM9 mod for A10s - General Questions and Answers

Yeah yeah, noob question! Prepare to verbally pants me.
Just bought a iView 756TPC tablet from the egg. Works pretty well some issues and chinese bloatware. Anyhow, want to flash this rom: http://forum.xda-developers.com/showthread.php?t=1760929
Only problem is I don't know whether to try the MOMO9 compatibility patch or the LY-F1 patch. Only differences I can find are I have 1GB DDR3 not 512MB DDR2. Both are almost identical hardware. I am leaning towards the LY-F1 b/c my buildprop shows Broncho which is listed as a clone of the LY-F1. I have googled a ton but it seems this thing is pretty new. You'll prolly find a few of my threads when you search and not much else! There is some info on the 760TPC which is from the same manufacturer. So basically I am confused as possible. I pasted some specs I exported from the systeminfo app. Hope that's enough to go on. Go ahead and rip me a new one.

Why yes, yes you can!
Got ClockworkMod Recovery working. Only issue is my buttons don't work. I have to use adb to initialize the recovery as well. Cannot hit the "back" key while in recovery mode but as long as you do everything right that's ok! I just flashed the LY-F1 version and it is SWEET so much faster than the stock ICS rom that came with the 756 from iView. However, my back, menu and home buttons don't work. They are not hard buttons but rather on the touchscreen part, probably related to why I can't use them to boot into CWM recovery too. The screen flickers a bit as well, but looks like with some tweaking I can get this baby running CyanogenMod9 :victory: Any other iView 756TPC users need some help getting going, it was not easy... let me know!

I'll just keep talking to myself!
OK, well neither of the compatibility patches will work with this tab so I guess I'm on my own. Oh well, I think I have the key mapping figured out and know i can easily change the lcd density so I can fix those no problem. It's including all the modules in the system/vendor/modules/ folder I am concerned about. There are a ton of those and I guess I am just not sure how they work and if I will have to customize the install script to include them in the existing patch. A lil' help would be splendid. I modified the existing Momo9 patch to include the updated key mapping and modified the script that changes the default cm9 lcd density, but I cannot get clockwork to execute my zip. Do i have to zip it up a certain way? I also added the vendor modules in the appropriate location inside the new zip, but I was not sure if I needed to add some scripting to copy them since there is no vendor folder in the existing patch i am modifying?? again if anyone is reading this I would really appreciate some kind of response!:fingers-crossed:
Thanks!

any update? how's it working?

Yeah, I had bought 2 of them.One of them suddenly had a pixel die, then the screen became unresponsive so I RMA'd them and bought a Samsung Galaxy 2. I could not figure out how to get the extra buttons on the touchscreen to work. I successfully remapped the volume buttons to serve as menu and back until I figured out the touch buttons. It must have something to do with a module for the touchscreen itself. I was going to try and insmod some modules (there are a zillion of them in the vendor module folder in the stock rom) and see what happened, then the pixel died and I said forget it. One thing I wanted to try was using a gingerbread rom for the 760TPC and see if it improved performance, but obviously never got around to it. The stock ICS Rom from iview was sluggish, especially compared to CM9 which the tablet ran admirably I must say. Anyways good luck!
One more note, to answer my own question just in case anyone else had it....
For some reason CWM did not like my winRAR zip files. Zipping them with 7zip default zip settings seemed to remedy the situation. I was able unzip the patch modify files using Notepad ++ and re zip with 7zip. CWM then would execute my patch just fine.

@RedForestStudios. Thanked you for each of your posts. You have given me some hope that I will be able to get CM9 on this little tablet. I didn't need it. I only bought it because I couldn't say no to the price. Any chance of detailing how you got CWM and CM9 on this? Did you use the method for the 760TPC?
I see you said you didn't get the buttons working. I'm assuming that was in CM9, correct? If I can get CWM on it I would be happy using ADB or QuickBoot to initiate it.

Does anyone happen to have a backup of the stock rom? i have searched the corners of the internet trying to find it as mine died on my second day of owning it but could be fixed with a flash of the stock rom. If anyone could help i would be very thankful

Iview has posted this full update on their site. Although I have yet to make it work. If you can get it to work let me know.
Their website is www<dot>iviewus<dot>com. Go to the dowloads page. Replace my <dot> with .

Spoke too soon
It looks like IviewUS has pulled the image. That may have explained the problem I was having after getting LiveSuit 1.09 to work.

From Iview
Iview says they are rebuilding their image file and the rewriting the instructions to the CyPad 756TPC. It should be posted in a few days.

Good to see some activity here in this thread. In case anybody wants/needs it RedForestStudios kindly gave me what he had before he returned his tablet. Sadly, I am too busy/lazy to learn what to do with it. If anybody wants it let me know. Meanwhile I'll reach out to him and make sure its ok.
What his zip included:
• cm9 – CyanogemMod 9 from XDA for AllWinner A10s
• CWM Recovery 5 ICS – CWM for AllWinner A10s (I think there might be some stray .ko and .kl files in their you can just delete)
• iview ICS – The stock rom from iView
• momo9_compatibility_1.2.0 – Don’t know if this is my modded version or not, cannot recall, you can easily find out by comparing to the original

I contacted the OP a while back and he provided me with some stuff he had and accomplished. Perhaps somebody who has one of these could use this to aid in dev? I am to busy/lazy to learn how to do this at this time.
I contacted him again today and he has agreed to allow me to pass it on should someone want it.
Included in zip:
• cm9 – CyanogemMod 9 from XDA for AllWinner A10s
• CWM Recovery 5 ICS – CWM for AllWinner A10s (I think there might be some stray .ko and .kl files in their you can just delete)
• iview ICS – The stock rom from iView
• momo9_compatibility_1.2.0 – Don’t know if this is my modded version or not, cannot recall, you can easily find out by comparing to the original
Also some notes from RedForestStudios:
Couple of notes, first make sure to use a text editor like notepad++ to edit the files unix/linux do not like the extra linebreaks or spaces windows typically inserts. If you happen to be using a program like dreamweaver to edit these make sure to turn on the unix compatibility mode in preferences, default is windows I believe. I think I was about to start insmod’ing modules via adb since I could not get the softkeys to work via mapping the the sun4i files. The key must be in one of the many vendor modules included in the stock iView rom.

Do you know if that stock image from Iview is the one they pulled?

Okay, Iview has posted the new image. I am still getting the same error. I am guessing these things are going to have to go back to the seller.

756TPC Firmware
I downloaded the firmware image and LiveSuite with instructions but was unable to get it to work. LiveSuite would come up with a box with a yellow triangle with an exclamation point. The instructions include a step to press the "back" button which doesn't exist on the 756. I had flashed a 760 to ICS a while back so I tried that version of LiveSuite. It included button captions in English. It also came up with the yellow triangle but the caption said "Invalid image file". I sent this info to one of the IView techs and am waiting for a reply. If anyone has any updated info I'd be grateful to hear it. Thanks to all for all the info.

That is what I am getting. Iview had posted they were updating the intructions. I have yet to see them.

I think I am giving up. I had sent in an RMA to 'nova unhatched chickens' when the thing originally died. They peeled off part of the serial number on the back of the tablet and broke the charger dongle. Then they shipped the broken thing back saying they could not verify the serial number on the tablet even though the serial number was also on the back of the glossy Iview box. After that, I contacted the credit card company to cancel the transaction.

Hey, I have this tablet also and it runs so horribly slow. I was looking for a way to get cm10 on it but after reading this thread it seems like that won't happen, let alone cm9. Most of these chinese tablets are clones. Does anyone know what 756 is a clone of?

I found that this tablet may be similar but I can't find any files for it on the web.

Edit:
Actually I discovered that it is a clone of a tablet called LY-F1.
Don't have time to look it up now but apparently there are several roms for it.

I actually got cm10 running on my 756tpc! But then I bricked it trying to fix the auto rotation lol. Everything worked except auto rotation and the touch buttons. I'll post how I got it running if someone asks.

im making this post for those that have 756tpc issues, and cant yet find much support. ( like me)
around 34(4 days out of warantee) days ago, i purchased 2 756tpc. they worked great, however one day, while my tablet was just plugged in to charge, i held the power button to power it down. After it came back up, the 1g of internal memory appeared totally full, and it said 0%. Also it said the apps on this space were like 80 megs or so. i must add that at one point i used system tuner to freeze a few apps, prevented a few user installed apps from auto firing, and moved a few apps to sd. as a final circumstance, the tablet appeared reset - nothing was installed, etc.
So, im thinking wow, i guess ill start over, well, no apk would install, because it thought the internal memory was full or non existant. when i went to hard reset, it would show the updating android screen, than go instantly to the laying down android with red exclamation point.
the tablet worked perfectly except for this. thats when i got on the livesuit path - well, at the time, not long ago, there was an image for the 756 on the iview website, which i pulled, along with livesuit. after figuring out that this image was fail(756TPC-20120903.img), i pulled the one they had listed for the 760, and flashed it on the tablet. this was how i discovered my image was bad, i initially just wanted to see if the 760 image would initiate -- it did, and it flashed. --for the record the image i had would just give a yellow exclamation popup with no text when i connected the tablet.
with the 760 image, the ram issue i was having was apparently fixed, and i had more hope. it was slightly different, rotation, nor cap buttons worked, but the tablet worked more than it did with the original issue.
so, after a few days, i called iview and an asian sounding tech answered - i explained the issue, and that i wanted the firmware. he told me that in 2-3 days the new one would be up on the site to download. he chuckled at the fact that i flashed the 760 image, and asked me what happened, and that they hadnt tried it yet. he chuckled.
so - after this, to continue on the "mission" -i saw kingofmyworld324 mentioned the LY-F1. after i saw them looking idential almost, and the same for specs - i didnt have to spend long before trying these images.
---
first i used ICS-Seby_8.04.7z - which flashed and showed an ugly boot screen before failing to load. i tried twice.
next i flashed :
4.0______20120315-a721-LF-y1.rar -its 4.0.3 ICS
works perfectly! -maybe even faster and better than the original firmware. theres a few small things that may differ, but -- niice.
problem solved.
i may or may not try the 756 rom if and when they add it back.
thanks!

[ROM] Androot-N7p-rom for Nextbook 7 Premium

Welcome to Androot-N7p-ROM for the NextBook 7 Premium *ONLY.
I decided to change up some of the apps and generalize the rom in terms of its boot-animation screen. It runs on LauncherPro (just choose it as the "always"/default upon first instance of it. The Launcher that comes with the device isn't so great, but I left it there just in case.
It's based on the first known rooted ROM for this device: 'DocHoppy's ROM'. Credit for most of this ROM goes to him and to 'Wendal' for his toolset for packing the ROM (into cramfs) for the Nextbook 7 Premium device.
As such, it is a beta/ work-in-progress.
Androot-N7p-ROM v0.2
[ 146 MB ]
download here
Instructions:
*WARNING: FLASHING THIS DEVICE WILL ERASE YOUR DATA AND APPS!!!!*
Download image.
Rename file to update.img
copy file to root of SD card.
Follow on screen prompt asking if you want to run update image.
Disclaimer:
I am not responsible for bricked devices.
Here's my changes..
removed:
-youtube player <- the real youtube app is better
-explorer <- redundant
-slide me app market <- redundant now that Google's Market is installed
-quick search box <- Google Search widget is better IMO
kept/added:
-Market <- the real Google one
-root explorer - an alternative & capable file explorer
-astro file manager <- we all know it well
-quickpic 1.5.2 - a much lighter & more efficient photo organizer/viewer
-3D gallery <- some love it, some hate it
-brightness level 1.0.0 - quicker brightness changes
-ConnectBot 1.6.2 <- for those that need a SSH tool
-Officesuite full <- may as well keep it
-Titanium Backup 4.6.7 <- has some very handy tools aside from backups
-LauncherPro 0.8.6 <- may be old, but it's smooth and capable
-superuser <- because this rom is rooted
-has some of the Google Apps (go ahead and add as you see fit)
-has a custom boot animation.

Click to collapse
Known Issue:
Apps2sd reports SU Binary out of date. Attemps to update this via superuser fails due to cramfs file system.
It's not perfect, but it does work well and I run it as my daily driver on my N7P.
Please give feedback or suggestions! I trust the pro devs could easily help me out with the little things!

Where do I edit the items that show in 'settings > about' in the device?
How do I change the default shortcuts that LauncherPro puts on the dock?
How do I change what icons are default on the home screen?
Where do I put custom wallpapers as part of the rom?

Hello, first of all, thanks for your work!
I am having trouble loading this rom. it says there's an invalid image file in my sd card and if I want to delete.
Now, I don't know if my tablet is a never or older version of what you guys have...
Next7p
2.3.1
kernel: 2.6.32.27
build: v2.0.7.....
my serial is also different from alot..it starts with YF0511
any help or tips?
In Dochoppy's original rom/post he mentions that the device will need to have a serial number starting with YF1011. That stands the same for this rom, as it's derived from his.
Having an invalid update.img firmware file could be due to a number of things, but the one I have here works on my device.
I wish I had more of an answer, but by all means try out the tools for repacking the rom.
So after messing around compiling a ROM, I forgot to add a launcher, and now I am stuck in a bootloop. After the girl in the dress is there for awhile, I get a black screen, then reboot. Anyone now how to fix this? I have been searching Google, but can not find anything yet.
Any help would be great!

I had mine half dead for a short bit until i found i could go into a low level bootloader mode and recover it. I am working on getting a the tool/images i used to recover mine uploaded and such.
Download and extract n7p_rescue_kit.zip
Reboot device using paper clip then quickly press and hold reset until you get black screen with usb plugged in
When windows wants driver give it the respective folder for your os (32bit or 64bit) from Drivers folder from the download
Run RK29update.exe if it says "Found RKAndroid Loader Rock Usb" on bottom you are good but if it shows "No Found RKAndroid rock usb" repeat last step.
Either flash all of the default selected items or do just system (since bootloop is in system)
Hope this helps
P.S. If you pack then unpack your custom one you can flash JUST system using the tool but be sure to use the offsets that are pre-loaded.
use a pin to push the reset button on the back to break out of the boot loop.
If after this your rom still bootloops, try putting a different update.img rom to flash, on to the sd card. Then boot into safe mode by holding all 4 front buttons after boot. the update should be found and installed after that.
Thanks!
I registered just to thank DocHoppy for all his efforts. I have a Nextbook Premium 7 I got for Christmas from Hastings, which fell into the YF09111XXXX batch. I used Wendal Chen's RK29xxImageTools_v2.1 to unpack the firmware upgrade from the nextbookusa site. I then put the Google apks, SuperUser, Rootexplorer, and re-packed it with a custom bootanimation. Because of my serial # I couldn't use DocHoppy rom without getting that "Invalid Update" error, but using their firmware seems to work.
My next goal is to find a way to get the "Accounts & Sync" into the settings! One of my apps is getting an "Error 42" which is an Android Market authentication error... however, other apps have worked without any problems so it's difficult to tell if that's the issue I'm having.

Install "Quick Sync Settings" to get to the hidden settings view.
Also did you use this guide for market? That one worked great for me.
Thanks
Working great for me so far. Thanks sharing your work.
Nice!!!
I have the image as well... Can you tell me how to open it or point me in the direction of a tutorial? I've been looking for weeks and couldnt find any info until this thread I have a yf091... as well. Thanks in advance for any help.

Not sure if this rom will work for you, just guessing by your serial number. If it is to work changing between roms on these tablets is very easy. Just download the image onto the root of your sdcard, rename it update.zip (not update.zip.zip) your tablet will recognize it as an update and ask if you want to proceed. If you say yes then follow the prompts and your in business!

Just go this to day and was plesantly suprised to find this rooted rom. Just wanted toy let you know that my S/N is YF12112xxxx and this rom work prefect for me (so far) Thanks for all the work you guys have done here. Also is there anyway to over clock the processor in out tabs?
Thanks for the comments thus far!
I would like to overclock this thing too, but that might be further down the road, as priority is on getting a different file-system for the /system volume.
Version 0.4 is coming next.
FYI:
There will be a larger span of time between updates on this particular rom for the N7p, because I will be using more stable conjumbles of things from other roms for this device. This rom is more of a remix or derivative than an entirely different rom.
Again thanks for all the hard work. I have a few requests. first since we cant change the Adhoc ( using wifi from another android device) on the fly with out RW access can you please add the ability to connect to adhoc wifi in the next build? Also i love google currents app but we cant use is on our device because we don't have map's installed. can that be added as well?

Most of the N7P roms out there now have Market installed and working. Why not just install these apps yourself?
I only suggest so because for the time being, the device is limited to its minimal capacity for apps without full-on apps2SD. Besides, for a tablet like this, you want to keep the system apps to a minimum and de-bloated for performance whenever possible.

Oh I was talking about currents and maps. Both of those can be installed via market. I have them both on my tablet.
The ad-hoc networking is something worth putting in a later release though.

[Kernel][Ref] Samsung Gravity Smart SGH-T589 Technical info & custom kernel project

[Kernel][Ref] Samsung Gravity Smart SGH-T589 Technical info & custom kernel project
The Samsung Gravity SMART is a low-midrange Froyo-based Android phone. It hasn't gotten a lot of attention because it's on an unpopular carrier (T-Mobile) and LOL QWERTY KEYBOARD. I intend to change that.
Technical Specifications
Below is information I've gleaned from spec sheets, Internet research, and judicious use of a loupe on my wife's broken phone.
Platform: Qualcomm S1 Snapdragon 7227 @ 800Mhz
CPU: ARM1136EJ-S
Touchscreen: ATMEL mXT224E
WiFi: Broadcom 4329
GPU: Adreno 200
RAM: 320MB, 275MB accessible
Bluetooth: ???
[more later--I'm at work and don't have all my notes]
Kernel development
I don't have anything to release yet. As a proof-of-concept, I've successfully compiled the sources provided by Samsung. It boots, but two big issues prevent me from releasing anything:
The coordinates on the digitizer are inverted--i.e. tapping the top left corner activates the bottom right, and vice versa.
The menu, back, and search capacitive buttons don't work at all.
Upcoming Features
Here's what I'm planning to add to the kernel once driver issues are resolved:
More CPU frequency scaling options
More scheduler/governor options
What's not planned
Gingerbread/ICS (phone needs updated boot loader to support 2.6.35 or later Linux kernels so we are stuck w/ Froyo for now)
I managed to hack the touchscreen driver to kinda-sorta work (at least the axes are correct now), but it's still not quite right. It's very inaccurate, which makes drawing anything (i.e. trying to play Draw Something) not work at all.
ATMEL has released drivers for the mXT series (including the 224E) but I'm having trouble getting it to work properly. Going to compare it against the kinda-working driver and see if I can fix it.
I found part of the problem, but I'm still having trouble with getting the driver to even load. Still, I discovered that the stock touchscreen driver only supports 2 simultaneous touches--the chip actually supports up to 10 simultaneous. I'm hoping to get the driver working so it's actually usable.
I have a friend with this phone i'm curious to see what you can do with it!
Man, this touchscreen driver is kicking my butt.
The official Atmel drivers don't work at all--the i2c call(s) fail during initialization and you get no touchscreen input.
The driver in the kernel released by Samsung is broken, too. In the default configuration, both axis are inverted so you have to tap the top-right of the screen to tap on something that's actually in the bottom-left. And the navigation buttons at the bottom don't work at all (menu/back/search).
So far all I've managed to do is at least get the orientation fixed, but the driver's still broken--you can't tap on anything on the edges (left/right), and the scaling is wrong so taps are mis-aligned in different parts of the screen. It's hard to describe, but comparing the output of YAMTT on stock kernel vs. compiled kernel shows glaring problems.
At this point I am trying to fix the Samsung driver, since it at least partially works. In the process, I'm doing a pretty massive code cleanup, mainly code organization and complete debug info that will make it easier to dissect exactly how the driver works and hopefully find the cause of the freaky behavior.
I've overhauled the debug output of the Samsung driver so that it's easier to parse via grep. The next trick will be actually fixing the driver.. but I'm going to be gone for annual training for the next two weeks, so things will be on hold until I get back.
I'm very excited to see what can be done with this for the phone.
This is my girlfriend's first android phone and while she's enjoying it, I want the experience to be better for her.
Good luck with your training!

This is my girlfriend's first android phone and while she's enjoying it, I want the experience to be better for her.
Good luck with your training!

Nice choice
This is a powerful device but unfourtuneally is an unpopular one, so there is not many developers with the Gravity
I strongly recommend you to install to follow and install this ROM on your girlfriend's phone: http://forum.xda-developers.com/showthread.php?t=1320187
Well, I've managed to get a 3.6.35.7 kernel to boot on the phone.
Samsung released the kernel source for the SGH-T589W which seems to be a Gingerbread edition of the Gravity Smart. The kernel builds successfully and manages to boot, but it gets stuck on a black screen. However, it does show up in the 'adb devices' list, so it's a start.
I believe the problem is the lack of both the OneNAND driver (AKA LinuStoreIII) and the RFS filesystem support. The modules from the stock kernel are compiled against 3.6.32.x so they don't work with the newer kernel.
My Google-Fu has turned up partial source for the same version of LinuStoreIII for the 3.6.35.7 kernel, and it successfully compiled. However, I haven't had any luck finding an RFS module.
EDIT: I think I found what I need, but I won't know until I get home!

NICE, keep us with update with the news :highfive:
Well, I thought I had something, but it's still not working quite right. I've got the parts for my debug cable on order. Should get here within the next week.
Well, I haven't yet gotten the serial output yet, but I do have a much more detailed output from dmesg now. I'm attaching it below.
Ugh. Samsung's OSRC is being a pain in the butt.
I contacted them requesting the correct driver. Their response: "That is the correct driver."
I responded, "Did you actually test it? Because when I compile the code you provided, the x/y axes are inverted." Their response: "Herp derp Samsung Proprietary."
My most recent response: "Don't give me that proprietary BS. The driver is GPL. If you used any of the code that's in that driver, you need to publish your modifications to it."
We'll see what happens next...
Your dedication to this project continues to provide me with a glimmer of hope for the 589. I thank you sir. Down with herp derp.
Sent from my SGH-T589 using xda app-developers app
Well, now they're claiming that the driver is the one they used in the shipping kernel. Oy!
In other news... I successfully booted Gingerbread on the phone using a stock kernel. I cheated a bit, though. I'll describe how I did it, in case anyone doubts me. The post is intentionally vague because it's not fully usable, wifi doesn't work at all, and I'm not currently at home and able to fully document the process. If anyone is actually interested in trying this out, I'll consider writing a script to automate it.
Known issues with this method:
- network time doesn't seem to work right
- wifi definitely doesn't work right
- usb mode doesn't appear at all
- The phone reports itself as a Galaxy Ace in the Settings screen.
OK, the steps:
First, the things you will need:
1) Stock SGH-T589 firmware (samfirmware.com has it)
2) Stock Galaxy Ace firmware (again on samfirmware.com)
3) unpack-bootimg.pl (google it). This is used to extract the kernel and ramdisk from boot.img
4) mkbootimg (google, or build from source). This is used to re-create the boot.img file
Steps:
- Start by unpacking each firmware package into its own folder.
- From the SGH-T589 folder, delete everything except boot.img
- From the Ace folder, delete everything except boot.img and system.rfs (MAKE SURE YOU DELETE arm11boot.img)
- Now, make an empty folder and copy the stock boot.img into it. Unpack it with unpack-boot.img.pl
- Make another empty folder and put the Ace's boot.img into it. Unpack it also.
- delete the boot.img-kernel.gz from the Ace's folder
- delete boot.img-ramdisk/lib/modules/*.ko
- copy boot.img-kernel.gz from the stock folder to the ace one.
- copy boot.img-ramdisk/lib/modules/*.ko from stock folder to corresponding dir of the ace one.
- copy boot.img-ramdisk/COOPER.rle from stock folder to ace one (optional, preserves the Gravity Smart boot splash screen)
- now, repack the boot.img-ramdisk folder into the CPIO archive
- next rebuild the boot.img file
- lastly, create ODIN archive with the rebuilt boot.img and the Ace's system.rfs
Flash the resulting tar.md5 file using Odin 4.40 USA.
Hi gblues. Very good work so far! Are you planning on porting CWM recovery? It's been ported to very similar phones, like the Ace, Gio, and Mini.

I used a similar technique (unpack, replace kernel/kernel drivers, repack) on the Galaxy Ace CWM recovery and it seems to work. Unfortunately, when I tried to use it to flash the Ace's ICS port, I get a black screen with "A N D R O I D" in the middle (note: this is after extracting the boot.img and doing the unpack/swap/repack process and flashing with ODIN). I suspect that ICS requires kernel features that simply aren't in the stock 2.6.32 kernel.
After doing some more long-term tests, my accomplishment above is a good proof-of-concept but it's not ready for prime time. Landscape mode is completely broken. Games like "Cut the Rope" only give you a black screen. The QWERTY keyboard is borked (mainly alt-keys). The SD card disappeared completely until a reboot. USB mode doesn't work. The accelerometer doesn't seem to work. The stock web browser crashes. Wifi doesn't work. The list goes on.
So that gets back to getting a custom kernel working...

[ROM][2013.01.09] Lenovo A789,P700i,A660 custom ROM (ICS)

I made a clean ROM based on the factory ROM for the Lenovo A789, A660 and P700i
Cleaned up ROMs:
- A789_S227_cybermaus_V2 (below)
- A789_S228_cybermaus_V2.1 (further below)
Ported ROMs (ported from P700i):
- A789_ROW_S105_cybermaus_ICS_V3 (further below)
- A789_ROW_S106_cybermaus_ICS_V3.1 (Further below)(also for A660 and P700i)
- A789_ROW_S107_cybermaus_ICS_V3.2 (Further below)(also for A660 and P700i)
The current and advised rom to use is A789_ROW_S106_cybermaus_ICS_V3.21
Based on factory ROM A789_S227_120827, and located in my Dev-Host. It is as close to factory as possible, which I hope will be good for stability. It is a flash-utility ROM, because it also holds the latest preloader, uboot and recovery. Assuming those are OK, followup fixes will be update.zip style.
Summery of changes:
- Rooted the phone with Chainfire SuperSu
- Set to boot in US-english, changed name of ROM
- Added MoreLocale for extra languages in 3rd party apps
- Removed Chinese apps, incl Chinese keyboard, removed SmsReg.apk
- Left Lenovo Security (anti-malware) and Lenovo (Go) Launcher intact
- Added Google GAPPS, Play Store, Maps, etc
- Added MobileUncle toolbox, SManager (root explorer). Titanium backup (free version)
- Added fix for location services
- Added CWMT recovery image (modded from 593cn.com)
- Added Skype, Whatsapp, and some others, as auto-install into userdata upon wipe
- Prepared busybox (you need to run script /system/xbin/installbusybox as root if you want it)
- Replaced bootup animation with clean Lenovo butterfly
- Replaced all some audio files with english named ones (thanks mabuc)
- Caller ID bug still present, sorry
- Just as a reminder, these ROMS have English and Chinese only.
Instructions:
By default, the ROM will not overwrite USERDATA or FAT. If you want a clean slate, first extract empty.userdata.rar and/or empty.fat.rar
- Read bgcngm flash tutorial.
- Read it again
- Start Flash Tool (v3.1222, in my Dev-Host)
- Load scatter file
- Take out USB cable and replace battery
- Press the download button in the flash tool
- Connect the USB cable
- Wait for the flashing to complete
A789_S228_cybermaus_V2.1 (no longer current, Use V3 instead)
Based on factory ROM A789_S228_120913, and located in my Dev-Host. Similar to V2, but newer, and a few extra fixes. It should be noted that the S228 is listed to solve unexpected crashes, so an important update in itself.
I do not have a A789, so it is a blind build. Until I get positive feedback, consider untested. Don't be the first to try if you are not experienced.
Summery of changes:
- Same as on V2, and additional
- Removed 2 more chinese apps that I forgot last time
- Prepared busybox (you need to run script /system/xbin/installbusybox as root if you want it)
- Added a tweak so USB-Debug notification is no longer shown
- Added a tweak so Wifi works on all 14 international channels (rather than only the 11 US ones, may be undone if you set a different locale)
Instructions:
This is a update.zip type ROM. So you need the custom recovery, see post #3,
A789_ROW_S105_cybermaus_ICS_v3.03
Based on P700i_ROW_S105_120920, see this separate post.
A789_ROW_S106_cybermaus_ICS_v3.11
Based on P700i_ROW_S106_121001, see this separate post.
Please note that this ROM I also build for the P700i and A660. See same post.
A789_ROW_S107_cybermaus_ICS_v3.2
Based on P700i_ROW_S107_121221, see this separate post.
Please note that this ROM I also build for the P700i and A660. See same post.
Below:
Post #2: Small review and fix of location services
Post #3: Custom recovery image
Post #4: Root your phone / install GAPPS
Also, many issues for the A789 are similar to those of the A750, so if you have questions, do search that Lenovo A750 thread to.
Thanks
Also thanks to bgcngm for his help, and to jazzor for his help

PS: do drop me a reply if you use or tried it! Or press the 'thanks' button.
So, I got my first glimps at the A789. So to speak. My colleague was holding it while we were audio-skype, so I did not actually see it.
His A789 came with a Etotalk ROM by Dean, which I now suspect is a reworked Smileyvvv ROM with Sony Experia interface. Not bad, but as you know, I am a 'factory ROM' guy. My colleague may also be, because he had already replaced the the SE launcher with GO Launcher, which is the default Lenovo one. Also my colleague said it jammed a few times, which it still has not done on my factory A750 ROM.
Most of the phone worked, but a few tips for others out there:
- The phone still has the Called-ID bug. Even though it is newer 4.0,4. I know some of you claim this is solved on ICS Mediatek, but I still claim it is solved in *some* of the cases, not all, it also depends on how your provider sends the caller ID info. Anyway, you can work around it with the prefixer app as reported before.
- It did not come with the MobileUncle tool, but with the Etotalk tool. Which was not updated for the new MT6577 chip, so it had no Engineer Mode. Install the latest MU tool (version 20120813v2.2.0 its in my Dev-Host), so you get one with MT6577 Engineer mode.
- Recovery Mode was hard to get into. Like the newest A750 preloader, you have to press the power putton *just before* you press both volume buttons. But it did came with the CWMR Touch, though its Touch function was broken, so buttons only. They probably simply tried recovery images of other models, and did not properly build one with the A789 kernel, but it does not matter, it works well enough.
- Location services did not work. Update the phone with the ICS_locationfix_v1.3 update using recovery mode. While you are in recovery, also wipe cache. And finally, go into MobileUncle tool, the MTK Engineer mode, and in location settings, change the NetLoc from MEDIATEK to GOOGLE. Now your location services should work.
Lenovo A789 Recovery
I created a recovery image for the Lenovo A789 based on ClockWorkMod Touch 5.5.0.4. However, I do not own a A789, so until I have reports of it working, consider it untested. You can download it from my Dev-Host: File A789_S22x_recovery_cybermaus.rar
NOTE: It has come to my attention this recovery works well, except the nandroid backup function, which is broken. If you value nandroid backup, install the APKHOT one below.
While doing this, I also found a full APKHOT distro which had what seems to be a CLockWorkMod (non-Touch) recovery in it, so I extracted that and also uploaded it. That too you can download from my Dev-Host: File A789_S22x_recovery_apkhot.rar
Both of them you will have to flash using the flash tool, using bgcngm's excellent manual, and the V3.1222 of the flash utilities and drivers, also in my Dev-Host. If you flashed my V2 ROM, you do not need to do this, as the recovery is already part of that.
Once you have the recovery installed, you can enter it by pressing both VolumeUp/Down while booting the phone. Due to an issue with the preloader, it may be needed to press the power button slightly before both volume buttons. If the phone seems stuck, it means the preloader messed up, remove battery and try again.
Inside the recovery (the Touch variant) you can navigate not only by its physical buttons, but also by screen buttons, and by gestures: swipe up/down for up/down, left for back and right for enter.
The first few people using this, please report your findings, good or bad.
PS: As alwasy, thanks to bgcngm for his unpack utilities, which I used to modify the recovery.img
Lenovo A789 Root; GAPPS, Location DIY
Its been mentioned before, but if you have a working recovery (like above, hopefully), you can always yourself root your phone. Simply install (from inside the recovery) chainfire's "CMW installable ZIP"
Link to his post: (ignore his big red requires root warning)
The file you need is labeled "CWM installable ZIP" at the bottom.
Direct link to the file you need to install via recovery update.zip
And while you are at it: You probably also want to install the latest Google Mobile Services (better known as GAPPS) from CyanogenMod V9:
Explaining wiki from CyanogenMod
The file you need is called gapps-ics-20120429-signed.zip and can be found here
You probably also want to wipe your cache partition after doing this.
To complete this DIY of fixing factory ROM: On Chine phone typically the location services do not work. Update the phone with my A750 V1.3 update using recovery mode. (it works on the A789 because it is a minor update, but *DO NOT* any of the other A750 updates on the A789. I repeat, do *NOT* flash A750 on A789). While you are in recovery, also wipe cache. And finally, go into MobileUncle tool, the MTK Engineer mode, and in location settings, change the NetLoc from MEDIATEK to GOOGLE. Now your location services should work.
Good luck
PS: If either update.zip refuses to install, remember to turn off the checksum and assert checks in the recovery.
And thanks to Chainfire for his work, and the team at CyanogenMod for theirs.

I fix the proximity thingy. it's caused by my lousy screen protector. But i've got another bigger problem now. I've accidentally uninstalled the default system home screen. I cant assess anything now. I tried flashing a recovery inside but it still doesn't work as factory. I use SP flash tool v3.1.222.00

Yes, a recovery is on the todo.
But for now, you did not answer my questions yet:
- Can you tell me what ROM you have? Or had. Original Lenovo Factory, Etotalk-Dean, some other?
- Which flash tools did you use to root? Or rather, which files did you flash using that tool to deal with root. Actually, the fact that you had to root it yourself probably means you had factory ROM, but please confirm.
As stated, I am uploading S221 original to my Dev-Host. Flash that with the flash tool. On short notice, that is all I can do. On longer notice, I will help you, but give me some time.
Edit: In fact: You you already have messed up your recovery, and I do not have a A789 to play with myself, you may be my guinea pig for the recovery build. So I will work on that today. (as today is not a working day for me anyway). If you do not mind being a tester. After all, the damage is already done, and you apparently already know how to flash using the utility.
EDIT: @ hwonggc : Please test recovery in post#3. Just update your post below with results, or PM me. I would like to avoid too many new posts on this while we are testing.

Yes yes. I had the factory rom. I got the phone just yesterday evening and this afternoon it's half dead already. I use smart phone flash tool to root using a file i got from http://www.fight.org.ua/publications...novo_A789.html. Everything was fine until I deleted the original home UI and the apex launcher also. So there isn't anything I can do. I'm downloading the S223 from some russian site and try, hopefully I can find some luck there. Downloading slowly~ sighhhh.
---------- Post added at 07:49 AM ---------- Previous post was at 07:40 AM ----------
BTW~ i'm willing to test out your rom too! I wouldn't want to sound too demanding, put please please put in the play store will ya?
I posted the custom build, see first post. It may take a while before I can get it uploaded, I am on a bad link.
Also, there have been 20 downloads on the recovery image. Come on guys, someone must be able to provide feedback about it working or not!
A789_S227_cybermaus_V2 ROM is working
Hello
Thanks for Your work.
Your A789_S227_cybermaus_V2 ROM is working.
Simple Flashing and start without problems. Now I must check some functions.
Thx again
basell
Edit:
The 3g connections don't work at first run. After restore they start but in My opinion with less sensitivity (compare to stock rom). It's look like A789 loose some frequency on witch can work.
Edit2:
And they have some strange behavior - After couple min of data connection (on 3G) they disconnect with information - "Restricted access changed" and the same is when I try to choose network manually. After that sometimes they login to 3G sometimes they change to EDGE.
In Stock version (S221) was not this kind of problems.
Edit3:
In place with good 3G signal I have no problem with data transfer.
How Can I check on witch frequency (2100,900,850) I have connected My data transfer?
Thanks for testing
Well, I definitely did not mess with any of the 3G stuff. So if it is true that 3G is less sensitive, then I would claim it is true for the factory S227 vs factory S221, and not directly related to my cleanup of it.
But (sorry to say so) I have learned to take claims of improved or degraded radio sensitivity with a grain of salt, even for the factory ones.
Having said that: Restoring S221 radio into S227 firmware is easy. The radio is separate firmware file, and I can extract the S221, S223 and S227 firmware in a separate file, so you can test. Were you actually using factory S221, or some other?
As to whether it is using 2100, 900 or 850: I can probably figure out how to get that info, *BUT* reality is that your provider most likely has only one frequency anyway. Most, pretty much all, EU providers are on 2100. The phone could not get to 900, simply because your provider does not have that frequency in the air (not for 3G anyway). And 850 is not supported at all on this phone.
Anyway, inside MU utility, engineer mode, bandmode, you can check/set the frequencies that are supported.
But please run a proper test if 3G is really degraded. As stated. it is so often a empty claim, I am somewhat careful to follow it. You want me to extract the 3 versions of firmware files in update.zip files?
Also, what country/vendor are you? please list the MMC and MNC from inside the APN settings.
Hi
If You will prepare this files I can test it tomorrow.
I'm from Poland and I have two frequency on data transfer - 2100 and 900. But I don't know if A789 use only one or change them. The place I'm test the signal is poor and I don't see if I work on 2100 or 900.
If You can, pleas tell me what kind of tests I can do to do that properly
Ok, here they are. update.zip type.
I only have S221 and S227, but the firmware files were indeed different, in more than just their timestamps. Of course, normally I would assume newer is better. So to make it clear: below files only replace the radio&dsp firmware, not the phone firmware.
Try to test honestly for yourself. Same conditions, same place, same time (because network load can make a difference)
It is possible that 3G really is degraded in S227, but as mentioned, I learned to not jump to conclusions just because the network is having a bad day.
WARNING: I retracted the two attachment, because I made a typo in the installer script. While the firmware is for the A789 (MT6577), the installer script is for the A750 (MT6575). Sorry. I will upload the correct ones in a moment.... Anyone that took a copy of these files before Oct 14, delete them!!!
I suspect the install would simply have failed, no harm done, but best to get rid of all copies anyway
BTW: basell, is that why you asked how to install? Really, if you ask for help, you should provide a bit more info. Anyway, I attached newer scripts, if you still want to try.
sorry for My question but :
How to install this firmware?
Like any update.zip on android. Go into recovery (see post #3) and apply the update.zip
i have the problem that the netlocation doesn't work with google maps, i flashed the cyber update 1.3, nothing changed, what should I do now?
And this is on what phone and ROM?
Anyway, to quote myself: "While you are in recovery, also wipe cache. And finally, go into MobileUncle tool, the MTK Engineer mode, and in location settings, change the NetLoc from MEDIATEK to GOOGLE. Now your location services should work."
many thanks, Cybermaus, netlocation works again after your instruction
Hi,
Thank you very much for building the ROM !!
I am using it for 3 days now and I am happy to report no problems with it. Everything works and most important: no more freezes !!!
my A789 came with the Etotalk by Dean ROM which was mostly OK, but was freezing from time to time (some days not at all, other days several times a day - most of the times when hanging up a call or, when trying to do wake it from standby: I was pressing the power button, but the screen would not light up).
Other things I like about this ROM:
- all phone functions work great
- Google Play works perfectly
- is rooted
- it has the Lenovo battery app, which is great! I am not 100% sure if this is the reason, but the battery life went from 1 day to 2 days
- I had no issues flashing it
- CWMT recovery works
Also, so far, I did not experience any 3G issues
I have written a small review of the Lenovo Security app, which you guys may want to put back on your phone if it was cooked out of it.

Thinking it twice, I've remembered another reason. One of the things I like most about the apkhot rom I'm using is that the external sdcard is mounted on /sdcard and not /mnt/sdcard2, which avoids problems with many apps. I tried one of the newest apkhot roms, based on s227, and none of the tricks to exchange /sdcard and /mnt/sdcard2 worked with it.
Click to expand...
Click to collapse
Well, that is actually an easy change to perform, just change the /etc/fstab.vold
However, if you go into settings->storage, the first option is default write disk. Change it from USB storage(the internal SD) to SD (the external SD)
So no hacking is needed at all.....
I've been running your rom for around 6 hours now. Everything runs fine. The 3G connection worked without much trouble. The only thing I haven't been able to do is performing a backup with the CWM Touch Recovery. So, I've just flashed the recovery I had on the apkhot rom I was using, using Mobileuncle tools, and now I've been able to create a backup.
So far, so good, and I've noticed a slight performance increase, too.

[Q] Can't flash A20 TV box!

Hello everyone,
I have bought various Android TV boxes in the past, and haven't had problems getting them up and running.
I recently ordered 2 chinese models from eBay however, which are giving me nothing but grief. I apologize in advance for such a loooong post, but I am at my wits end and I am really hoping someone can help me out.
The action was for this model here:
www.ebay.com.au/itm/231275032090
It appeared to be a pretty standard model, like a Justop 4.0, but with a hard switch where the optical should be, and a cut down remote.
Firstly, the Specifications according to the auction:
1GB ddr3
4GB nand flash
Allwinner A20 dual core 1GHz CPU
On closer inspection after receiving the unit, an additional physical difference is that the reset button appears to be between the USB ports, instead of behind the AV out - not a big deal.
After powering it up, I am having huge problems with them.
Firstly though, what the software says about the hardware:
Advanced Settings/About Tablet:
Model Number : BBA22
Android Version : 4.2.2
Firmware Version : V2.0
Kernel Version : 3.4.39 [email protected] #10 Wed May 14 22:36:36 CST 2014
Build Number : BBA22-UI4-V2.0.1
And what Droid Info says about the (relevant)hardware:
Model : BBA22 (sdk-normal)
Manufacturer : unknown
Chipset : sun7i
RIL version : sw-dataonly-ril-0.5
Build Number : BBA22-UI4-V2.0.1
Build Bingerprint : softwinners/ninss/ninss4.2.2/NinssSoftware/20140521:eng/test-keys
OS Version : Jelly Bean MR1 (4.2.2)
SDK : 17
CPU Architecture : ARMv7 Processor rev 4 (v71)
Now, the BIGGEST issue these things have, is that at random points of use, it comes up with a message "Warning - System configuration is inconsistent with the production configuration, please contact your supplier, thank you!". This message will flash over and over again for anything from 30 seconds to half an hour. I half suspect it has tablet code SOMEwhere in it also, as it keeps coming up with 'touch the circle' walkthroughs for applications like avia. This might be unrelated though, I have no idea.
So anyway, I have tried doing the Justop 4.0 flash method with a SD card, however it will not turn on if there is a card in the slot. Also, when you hold the reset button down and power it up, it does not seem to go into the diagnostic mode so I can't flash it that way either. I am guessing the ONLY way I can update short of soldering in a serial port, is to use the backup/restore function.
I read through this whole thread here, but cound not fine anything to help me:
http://forum.xda-developers.com/showthread.php?t=2398632
If anyone has any ideas, please let me know, I seriously can't get anything to work. I thought maybe the 'hotspot' being enabled was causing the incinsistency problem, but I used a process killer to stop that at startup, still no luck. Doing a system reset through advanced config didn't help either, I got the error almost as soon as turning the unit back on.
I've attached pictures of the error I am getting, the top of the board, and the back if the board.
Cheers,
Smak
PS - I am yet to hear back from the seller, but if I ever do, I will post the result here...

I seem to be in a very similar situation. My device also reports as being "BBA22" but it's a different form factor and the identification on the board is "TXCZ_A20_v1.0". I tried contacting the people that made the board (Shenzhen Tianxing Chuangzhan Electronic Co.) but they refused to help. I also tried contacting the company that made the firmware images (Shenzhen NINSS Technology Ltd.) and they also refused. The supplier I bought the device from says they have the image file but they can't seem to figure out how to get it to me (they tried emailing the +200mb file then they gave up and stopped responding). The build number on my device is "BBA22-UI4-V2.0.4" so apparently there's an update available that may work on your device.
I'm pretty sure you need to flash the image using the Phoenixsuit program to make a special sdcard that you place in the device and boot from to reflash the device.
Please post your image file if you ever get it!

That is good to know, I might email them again now. Will let you know the outcome!
OK, so I got a reply from the seller.
I've attached the patch file and the instructions to this message, but theres a few things to note.
- Its only like 20 meg big, so it isnt a full firmware update
- The instructions talk about pressing the reset button at the start.., I don;t think this is neccesary if its rooted already
- The instructions are VERY engrish-y, basically just dump the update.zip onto a sd card, and apply the patch through the settings menu
- The default language is changed to some form of Chinese after applying, theres plenty pictorials on how to change the android language though.
- The version has been updated from BBA22-UI4-V2.0.1, to BBA22-UI4-V2.0.3 - This is still lower than the one you mentioned @ BBA22-UI4-V2.0.4
So far though, I have re-installed all my apps, and haven't seen the error.. yet. I was a little concerned it is still giving me touchpad tutorials, but mouse mode on the remote is making short work of those.
I'll just have to wait and see, I guess.

That seems very promising for you! Unfortunately it probably won't help me at all... It sounds like it's a sort of update patch instead of a whole image. Starting the device with the reset button causes it to load the recovery partition instead of the regular partition (I'm guessing you saw a green android with a text menu with options for recovery). I full flashing would/could involve an SDcard, but I think you would have to create it with Phoenixsuit and not just copy the file contents over (it would then just boot directly from the SDcard and you wouldn't need to press the reset button).
In my case, both the regular boot partition and the recover partition are wrecked so I couldn't even try this patch if I wanted to.
Thanks for posting, though... Hopefully it helps someone else out.

Hmm, is clockworkmod still a thing? I could try taking a backup of my ROM and see if that's something you can use.., only problem is I will need a bit of time. If I get a chance, I'll do it over the weekend. I will need a place to dump the image though, it will be too big to attach here, can sort that out later though.

I'd appreciate that... Your board seems to have a completely different layout, but all the same components. I'm not familiar with clockworkmod, though, so I'm not sure how that backup would work. I guess I'd need to get clockworkmod flashed on to the recovery partition first and then I could flash the backup to the NAND from there?

I'm not actually too sure. The last timed I used clockworkmod was for flashing a galaxy s2 phone, so I'm not even too sure if its still around or compatible with tv boxes. There will definately be SOME sort of tool though, that can take a full backup suitable for restoring. I'm about at the limit of my knowledge, so I am sort of playing by ear and going into a google-learn-try sort of cycle as I try different things. Maybe someone with more experience will stumble in here and let us know what we need to do
This is interesting... I found another device with an identical PCB board: YBKJ_A20 (I can't post links yet, but a Google search will find it) Several chips are different so the firmware would differ. It's so hard to work with these devices when no one claims credit for making a lot of these things!
What is J4?

I was wondering what the upper left 2 pin connector is for? (the little white 2 pin plug next to the USB)
Is it SPDIF? Power input? output? Something else? I see in this picture a cable connected so i'm hoping you can tell.

So... For everyone looking for a full firmware for this box, and stumbled upon this thread from google like I did: DESPAIR NO MORE.
I found a compatible firmware for this device (exacly as described and same board as the one OP has) It will work even if your box came preinstalled with another software version, but its the same hardware
Found it in another thread, posted by @daaviles30 Its not EXACLY the same as the one I had originally loaded but appears to work without any issue whatsoever (even the remote works), if a little bit better.

Wow.
The Phoenixsuite makes an sdcard that flashes the internal memory. After it's finished flashing, you take the card out and it runs off of the internal NAND. That's it. It never runs the Android from the sdcard.

Rooting
Always remember, you root your device AT YOUR OWN RISK. Rooting will void your warranty and you may brick your device in attempting this. Its a choice and you're the only one who can make it.
Rooting instructions (tested up to RCA firmware 1.9.50):
(Beginning with a tablet never before rooted, or has been completely unrooted prior)
1. On your tablet, go to Settings > About tablet > Build number and tap the build number 7 times. This will unhide the Developer options menu.
2. Tap the Developer options menu. Enable it by sliding the slider to the right in top bar. Select "USB debugging" by placing a check mark in the box next to it.
3. Go to Settings > Security. Select "Unknown sources" by placing a check mark in the box next to it. Deselect "Verify apps" by removing the check mark in the box (you can enable it again afterwards if you wish).
4. Connect your tablet to PC via USB.
5. Download the Windows iRoot rooting application here.
6. Install the app.
7. Start iRoot and follow instructions to root. Remember to enable USB permissions on tablet when prompted.
8. Once successfully completed, download and install SuperSU from here to replace the Chinese root manager called Superuser 1.0.4.
9. Start SuperSU and you will be asked for permission, choose to allow.
10. SuperSU will prompt to install SU binary, go ahead with OK and install normally (not TWRP). IT IS VERY IMPORTANT TO INSTALL THE BINARY.
11. Once SuperSU is installed and the binary updated, you can uninstall Superuser 1.0.4 and the second app it installs, something like "Clean Master" (unless you want it).
Happiness is now achieved with having a rooted device
* For further details regarding root, please see "Rooting considerations" in the Misc. section below.
Custom Recovery
Always remember, you install a custom recovery on your device AT YOUR OWN RISK. Installing a custom recovery will void your warranty and you may brick your device in attempting this. Its a choice and you're the only one who can make it.
99% of the credit for this section goes to johnemc2, PatF and mexicandroid for creating and contributing to this thread. Although it was created for a different but similar RCA tablet model, they provided everything I am going to reiterate here. Also the original thread for TWRP on MediaTek devices (which is the chipset for these RCA tablets) is here, and all credit goes to yuweng for this. Make sure to hit the thanks button in the respective threads for these guys!
TWRP installation instructions (tested up to RCA firmware 1.9.50):
1. Device must be rooted. See rooting section above or use another method of your choice.
2. Download the TWRP recovery image for the 6203 from here. Rename it by deleting "[RCA 6203 TWRP - Remove this tag]" so that the file name reads only "recovery.img" (with no quotes of course).
3. Place this file on your external sdcard.
4. Download and install [ROOT] Rashr Flash Tool from here. If the app suggests updates, go ahead and install them.
5. Rashr will ask you to make a backup. If you try, it will fail. Not to worry too much though, a stock recovery image is available below.
6. Start Rashr. From the menu, tap Recovery from Storage. From the "Pick a file" menu select /storage/emulated. Select /storage/, then select sdcard1/. From there select the recovery.img file you saved in step 3.
7. It will give you a warning prompt asking if you are sure. If so, select "Yes please" to install TWRP.
8. Upon successful flashing of TWRP you will have the choice to boot into the custom recovery, go check it out!
9. One procedural maintenance item to perform after: I have noticed that the rashr app holds on to a large amount of data for some reason and haven't found the need. Once you reboot, you can go into Settings > Apps > All and find Rashr and clear data to reclaim the space.
Good guide for using TWRP can be found here.
How to manually get into recovery (TWRP or stock):
From a powered off state, simultaneously depress the power and volume up buttons until the white RCA boot screen appears. Once this screen appears, release the power button but REMAIN DEPRESSING THE VOLUME UP BUTTON until you are in recovery.
Stock recovery installation:
It is the exact same procedure as was with TWRP, with the exception of step 2. Instead download the stock recovery image from here, rename it by deleting "[RCA 6203 Stock Repacked - Remove this tag]" so that the file name reads only "recovery.img" (with no quotes of course). Continue on using step 3 above. Check out why you might need the stock recovery image in the "Firmware updating considerations" area of the Misc. section below.
Ultimate happiness and assurance is now achieved with having a custom recovery installed on your device to back it up!
Accessories
Here are some of the accessories I am currently using for the 6203:
Cases:
The keyboard case is good, but I found it cumbersome in most cases and unnecessary. So I purchased this case from Ebay. Here are some photos of mine. I have had it for 5+ months with no issue upon daily use.
Screen Protectors:
I purchased this anti-glare and anti-fingerprint screen protector from Amazon. Although they now have it for the 6203, at the time they only had them for the 6103 and I had to modify it. But 5 months later it is still great. Being anti-glare means there is a slight matte to them, but overall I found it hardly effected the clarity of the screen. It really kept having to wipe off the screen due to fingerprints to a minimum!
I am just sharing what I have found to work for our devices and hope it helps you too in some way!
Customization Apps
Customization apps that require root (seeing rooting section above):
Xposed Framework. Man is this awesome. Here is the description from the site: Xposed is a framework for modules that can change the behavior of the system and apps without touching any APKs. That's great because it means that modules can work for different versions and even ROMs without any changes (as long as the original code was not changed too much). It's also easy to undo. As all changes are done in the memory, you just need to deactivate the module and reboot to get your original system back. There are many other advantages, but here is just one more: Multiple modules can do changes to the same part of the system or app. With modified APKs, you to decide for one. No way to combine them, unless the author builds multiple APKs with different combinations. You can find version 2.6.1 for our tablet here (select "show older versions" at the bottom of the page).
GravityBox [KK]. TONS of customization for our device. Find it here.
Customization apps that do not require root:
Blacked out or inverted apps. I love darkened apps. I prefer a black or dark background to most apps. It looks good and is easier on the eyes! You can download the Team Blacked Out updater apk from here. You can download many popular apps that have been "blacked out" by this team.
I am just sharing these apps for fellow fans of customization. Enjoy!
Custom ROM's
[reserved]
Misc.
Rooting considerations:
Although there is a risk of bricking the device in doing so, to date I have rolled through both the 1.3.51 and 1.9.50 RCA updates without the update being hindered by having my device rooted prior (never unrooted), and I have not lost root once the update completes. Although I have not tried this without, I believe this may be because I use SuperSU Pro OTA survival. This app is not necessary, but the free version does not have the "OTA survival mode" that the pro version possesses. I recommend spending the $3.75 for purchase.
Firmware updating considerations:
If you delete any of the bloatware apps that comes preloaded (VUDU, Walmart, Sam's Club, Opera, etc.) and try to update the device, it will soft brick your tablet. This is because the update performs a core app comparison check to test validity prior to completing installation. You will only be able to get into stock recovery once this happens. Therefore my recommendation is not to delete any of these apps but instead use Titanium or MyBackup Pro to freeze them, and prior to attempting any firmware update remember to UNFREEZE THEM FIRST. This will save you any headache with the firmware updates.
I do not think you can install an official firmware update via TWRP, so you may need to reinstall the stock recovery to do this. See the "Custom Recovery" section above.
Misc. #2
[reserved]
One frustrating thing about our device is that some apps will not install from the Play store. It will state "this item is not compatible with your device". Well I have tried many methods to circumvent this, including changing prop files and using apps that fake screen densities. I don't recommend that . Instead I sideload. I use a Google Chrome extension called APK Downloader. You can get it here. To set up it will ask for devide ID info. I plug in the number for my S4. Once downloaded, I just copy the apk over to my tablet and install from there. The only caveat to this is that it does not work for purchased apps.
There are other ways to procure the app and sideload, but this is the method I use most often for the 6203.
I have a support request in to RCA for these concerns (here is the text as I sent):
Hello,
I have 3 questions. The first is that by reading the specs for this tablet the CPU is supposed to be set for 1.5Ghz. But when you use the tablet, it is only set for 1300Mhz (1.3Ghz) (I can provide screenshots). Which is wrong and why?
My second question is do we have any access to a complete firmware ROM that can be used via recovery? This would be nice to have in case the tablet is soft bricked for any reason. Update ROMs do not provide this.
Lastly, is there anywhere to download USB drivers for this tablet?
Thanks in advance for your help.
From RCA:

1) The max threshold is 1.5Ghz. The reason it is running at 1.3 is probably because your not using its absolute full capacity
2) We dont have the ROM
3) Is this for the USB stick or memory stick?

#Madeforyourlifestyle
My response:
Glen,
Here are my responses:
1. I have attached 3 screenshots from independent apps that all report the CPU set for 1.3Ghz and not 1.5Ghz. In fact they show the governor as having the range for the CPU set to 598-1300mhz. I believe this happened in the firmware 1.9.50 update and was not the case prior. Can you check to see why this was done? We purchased tablets that were intending on having a 1.5Ghz processor.
2. You will see many returns then from tablets that were soft bricked due to the most recent update corrupting the system file, and then only allowing people to boot into recovery and not into Android.
3. No, USB drivers as in this explanation: http://developer.android.com/tools/extras/oem-usb.html
Thanks. I really appreciate your assistance with these questions. Please let me know if there is any other information I can offer.

The tablet will use the 1.5Ghz only when it will take big update like firmware updates.
#Madeforyourlifestyle
My response:
Glen,
There is no way for the Android kernel to know only to use full CPU capability during an upgrade procedure. Its there for all operations or it is not.
Can I have my concern escalated to your engineering team? As I said previous, the system showed 1.5Ghz was available in processing speed before the last upgrade.
Thanks
From RCA 5-7-15:
Hello,
We'd love to hear what you think of our customer service. Please take a moment to answer one simple question by clicking either link below:
How would you rate the support you received?
Good, I'm satisfied
Bad, I'm unsatisfied
Conclusion:
So apparently RCA doesn't intend to do anything about the most recent update failures outside of performing RMA's for people, and also doesn't care to answer why these tabs are advertised as 1.5Ghz and are being throttled to 1.3.

What can I do with this or this - no ROM Backups, and an annoying 'brick' on my table?
I successfully rooted with KingRoot and tried to manually switch to SuperSU with a script I found.
The script seemed workable. I found all of the targets and: # root.sh ... oh *hi*
The transition failed and after trying to 'clean up' remnants the script seemed to have missed, the screen froze: RESET BUTTON - nothing, nothing, nothing.
I wish I hadn't believed it would work without a 'dd ... system.img'. The tablet had about 12hrs mileage and is now a very new [Black Friday] $49 item about to be smashed on the driveway.
I read somewhere that RCA will not be distributing winusb drivers.
*uc* it - i b-roke i-t! :victory:
It's Alive! After the battery drained, 2 weeks later, it booted!
removed supersu

probeafargavin,
Sorry for slow reply. Been a busy month! I recommend sending the unit back to RCA for an RMA. I had to do this once and although it took a month, I received back a working tablet. It doesn't matter that you did this, they will not check. They will end up sending you back a refurbed tablet. Mine works fine.

Needing Help
I rooted my device (same exact make/ model you have listed). Well it just so happens that now I am not able to open the Google App store. I have clicked the app logo so many times now and all what I see is what looks like the app is about to open but it just disappears about a half second later.
Looks like I am no longer able to use the back button also. I have tried factory resetting the device yet problem remains. Clearing cache of the Google Play app, no results. Please help!!!!! I would surely appreciate it, I'm sure you can imagine how devastated I am over this.

C_Cee unless you have TWRP installed and had a back up, there is not much you can do. I would RMA the tablet through RCA. I had to do this once and it was a pretty quick turn around.

RCT203W46L Questions
Hi,
I have just purchased the above and rooted it with Kingroot. This is the lollipop 5.0 version.
a) a stagefright detector from lookout reports this device is vulnerable to this hack. Any thoughts?
b) are the twrp and stock recovery images pointed to by droidify post #2 and #3 still usable? even though its lollipop5.0?
Any help appreciated before I mod this thing!!
Thanks

Lollipop is going to have a different recovery, so what I posted likely will not work and may cause serious problems if attempted. Not sure about stagefright vulnerabilities.
Any advance?
No more advance in this device?

My tablet is still going. Although not my daily driver device, I use it to watch videos on break at work and to read on. There hasn't been any development for this device that I am aware of and unlikely to be considering it is not that popular.

Aloha -
I just received one of these today:
Model: RCT6303W87DK (32GB)
Android version: Lollipop 5.0.
Kernel: 3.10.54
Build: RCT6303W87DK-ANDROID5.0-V63-V1.12.20-B
I installed NewKingrootV4.62_C133_B233_en_release_2015_11_24_105203.apk downloaded from www\.kingroot\.net
On the first attempt, Kingroot rebooted at 22%, and failed to root. I repeated the procedure without rebooting, and achieved root on the second attempt.
I am curious to know if you flashed TWRP and, if so, what results you had.
Also: does anyone know if, in fact, the 5.0 loader actually is different from the 4.4.2 loader.
Thanks in advance.
I'm confused, is this thread on the RCA Pro 10 RCT6203W46KB or for it's successor (I assume) the RCA 10 Viking Pro RCT6303W87DK. I ask because I have the RCT6303W87DK and am looking to see if there are any ROMs for it, as I would prefer to be running Android 5.1.2 or 6.0 over 5.0.
