CPU-Z only states that the board is the rk30sdk chip and not the whole rk30xx in detail. It should be capable of running higher than 1.2GHz since some of these 40nm processors are running at 1.6GHz. They were in production sometime in 2012. It states that the maximum display size is 1920x1080 even though its just running at 800x480 on these 7" RCA Tablets.

Here is some more information i found:

Info on RCA tablet

Hello all I'm new here and looking to join in on this thread as I just got me a (RCA RCT6077W2) tablet and want to get the best from it.

First tablet for me and know nothing about them and how to get the most from them.

So stupid questions may pop up :confused:

I have followed and used the Kingo ROOT and got the USB to connect to my Win 7 computer but that's it

Thanks

RCA Tablet a single core

Well I have been conversing with RCA and they say this tablet is a single core so you can't upgrade to V 4.2 J B or up so this thing is pretty much a DOG of a tablet and not much can be done to it.

RCA tells me this an upgrade is a NO GO Android 4.1 is it.

Well I got this thing for Free so no lose to me I'm selling it off.

If anyone has any Ideas for any upgrade I'm listening :cyclops:

Please someone help!

I bought 3 RCA RCT6378W2 for my kids for Christmas when I went to set them up the first one went off without a hitch updated without a problem. However the other two I'm not able to update. I go to settings>about tablet>System updates>Auto check update>on there is a button below which says check now and when I click it nothing happens on either tablet.

Model# RCT6378W2

Android Version- 4.2.2

Kernel version- 3.0.36+

EM3168_791A@V02#199

Mon Aug 12 23:37:17 CST 2013

Build# RK30_ANDROID4.2.2-SDK-v1.00.00-FirmWareVersion-V1.00

JDQ39

I contacted RCA about this and they replied with instructions to do a hard reset.

1. On power off mode, press and hold on VOL+, then press Power button until you see RCA+Dog opening screen. Waiting for a few seconds, release VOL+ button until you see the android on its side.

2. Press and hold on Power button, then press VOL+ button once.

3. Volume up/down to highlight "wipe data/factory reset," then press power button to select.

4. Volume up/down to "Yes—delete all user data," then press power button to select.

5. When you see "Data wipe complete," press Power button to select "reboot system now." The system will be restarted.

6. After the above steps, you will see the initial setup interface.

Here's another kicker....I can't get either tablet in hboot mode! When I hold down the vol+ button plus the power button the screen just flashes once and doesn't do anything else. When I hold down the vol- button and the power button I get the RCA dogs then that screen goes away I release the volume button and nothing more happens on either tablet! This is very frustrating considering that it's 4 days until Christmas and I am going to have 2 very upset little girls! Please someone help me!

Best answer return the bad unit after using my RCA unit I'm not impressed with their quality.

Their support even though you get a PERSON is not quality support probably just reading off a script basic answers do this do that.

I have a long background using Windows from 3.1 to Win 8 and Android is one weak operating system very basic for a phone its ok but as a operating system It falls on its face ASAP.

If you want a useful tablet go windows or an ipad 1000% better Android is just to simple to be more than a web surfing or email machine that's it.
[General Questions and Answers] RawSarcasm:
Bad comparison!

I don't usually post on anything but this is an unwanted opinion, sounds as though you are comparing an OS for a PHONE/TABLET to an OS made for PCs. Android and IOS are basically the same in use so that was a waste to add the comment about an IPad. Windows I can't really say since they have 2 versions of their OS for tablets. Though my point stands that its made for simple things because that's what phones are, lol.

---------- Post added at 06:29 AM ---------- Previous post was at 06:21 AM ----------

Don't take their word for it as there is more than one version out there, use any benchmark app or hardware checked to see which you have.

Also I've been looking around and I think the best option for an update is to contact developers of the most popular custom ROMS and ask if they plan to support some of these devices. I say this because as KitKat is here and supposed to support low-end devices there should be an increase in support for affordable android devices.

*I've left an email for the guys at SlimRom, I wonder if enough of us ask for support will they see a need for it.

Root + link2sd works for getting apps on sd card.

as far as finding the ext sd card. most apps ive used you have to backup as far as you can see ..

you have to find the folder called

mnt

then external_sd

then you are at the root of your micro sd card
[General Questions and Answers] Androiduser11:
That Explorer that came with the Tablet is just basic. You'll need to download a more advanced File Explorer like ES File Explorer for example. Also you shouldn't have any issues locating any roms for the emulators. Just as NiMaD83 had mentioned, you'll need to go into mnt folder in order to locate the External SD. I have NES, SNES, GENESIS, and N64, found all of the roms and set them up for their folders. I haven't installed PPS, so i'm not sure if the build has bugs or something else you aren't doing right. Also, when i installed Clean Master, i remember an option where you can move Apps.

This is especially useful to those of us with the W22 as its a single core. i can live without roms as its possible to change the stock launcher by going n2 root explorer /system/app and renaming launcher2.apk to launcher 2.bin and replacing with new launcher such as GO Launcher and renaming it to launcher2.apk this is a simple root trick that can be used on any android device as far as i know. i pst this tip as i noticed this is many users first android device and their first root and its pretty helpful as far as customization goes, also for those of you who are rooting for the first time check out rom toolbox

ADB Drivers for RCT6378W2

My kids each got one of these for Christmas and I spent a couple days beating my face against them trying to get ADB working. Here's the write up on how I got it working.

http://ryancuda.blogspot.com/2013/12/how-to-get-working-adb-drivers-for.html

I covered Windows 7/8/8.1, Mac OS X and Ubuntu. The process is pretty much the same for all three, the magic is in editing the adb_usb.ini file.

For the TLDR people, here are my hacked windows drivers

https://drive.google.com/file/d/0B2sTxsvBXUwpb2NvYmRNR2dKVXc/edit?usp=sharing

install the driver, run 'android update adb' then add '0x2207' to ~/.android/adb_usb.ini. restart the ADB server and voila. You should then be able to use either Super One Click or Kingo App to root.

[General Questions and Answers] Androiduser11:
Which procedure would you recommend using to root the RCT6378W2 tablet? What

N00b-un-2

has mentioned in his post #93 or how

Takenover83

used PDANET which he has explained in post #4? My main concern for KitKat 4.4.2 is, does it really help the battery life compared to Jelly Bean 4.2.2? I have disabled Wifi, Data Sync, GPS, lowered brightness, all sound volumes, all manually since i've noticed that these battery saver applications don't help that much, but hopefully they have changed alot of things in KitKat compared to Jelly Bean to make it more battery friendly.

Also once i do root and go along with what you have fixed up for us, the System Update won't be working anymore, correct? Like the bloatware applications that i'm noticing won't be updating anymore, but how about the applications and games i'm downloading from Google Play Store, would they be able to update? Anyhow thanks in advance.
[General Questions and Answers] giveen:
LOL, slow done on the questions.

1. Yes, install PDANet, and let it install those drivers, then use the kingo root program

2.

IF

I can achieve a successful rom, what we

SHOULD

see is significant battery and performance increase as we have a more modern kernel.

3. Never use a battery saving app. Everything you have done is a good thing so far except those app.

4. KitKat was designed for lower-end devices in mind, but first I need to achieve 4.3 to ensure that a successful ROM can be passed to 4.4

5. Yes, this will break RCA's update system, so I will highly suggest a nandroid backup before hand, which will be possible as soon as I get the recovery built.

6. Your apps will be able to be updated just as normal

Please be patient with me on this. I have many things going on in my life

1. I have three young boys, and my first baby girl on the way (due in April)

2. I am in college (at home study :) ) currently doing a leadership class and studying for my CCNA.

3. The wife gives me dirty looks if I spend too much time on these things and "break" the boys tablets.

[General Questions and Answers] Androiduser11:
So I started installing PDAnet v4.12 on a laptop with Windows 7 64BIT, but right when it asks for the Tablet to be connected via USB it won't recognize it. It just sits there on the USB Driver Installation. I enabled USB debugging and even turned off then on the Tablet and it still will not be recognized by the laptop. In the Device Manager it just says USB-to-USB Bridge 2.0(PL2501) with an exclamation mark.

Update: So I found the drivers for USB-to-USB Bridge 2.0(PL2501), but now it keeps on bugging me with Windows Easy Transfer and the USB Driver Installation screen for PDAnet hasn't started to install anything yet either.

My progress so far; I've managed to pull in the CM10.2 sources, set up my build environment, make the otatools, decompile the boot.img and recovery.img, and I have just built CWM recover 6.0.4.5 from source referencing the files from the RCT6378W2 boot.img for recovery.fstab among other things. My research show that the Rockchip CPU in these tablets is a cortex A9 chip so in BoardConfig.mk I added TARGET_CPU_VARIANT =: cortex-a9 and the project compiles without any build errors. however, the resulting recovery.img didn't work. I just flashed it over the stock recovery and then did adb reboot recovery, but the tablet wouldn't boot into recovery so something is wrong. It would be nice to have all the source files for this tablet.

2) the correct device to flash recovery to is /dev/block/mtdblock3, eg;

su
