[Tutorial] CMP741D Jellybean Install

[mastermind278]

ROM Works Great and it fixed my signing-in issue with the My Little Pony Gameloft Game

EDIT: 1. Thanks for also helping me with installing a working CWM for the tablet and 2. The one thing that bothers me is that the icons for the Notification Clear (The X for when you check on what's in your Notifications) and the Volume Up and Down Icons are not showing up, any way on how to fix this?

The Jellybean notfication is different from ICS. To clear out you use the _-^- there no longer is a X.
As for the volume, there are a few apps that will add the volume indicators.

I might redo the modelfix in the coming days/weeks depending on how busy I get to hopefully add them. Personally I am leaning to reasigning the volume buttons to the Menu and Esc button (if people like that).

Thanks for that, I never knew
that JB's bar was THAT different

How can I reinstall the original os if I even can if I did not back it up?

Yep, Go to Craig Electronics' Official Website (craigelectronics.com), go to E-Digital, then go to CMP741D and scroll down to the "Download" link and download the archive, after that, extract the update.img from the folder within the archive into the MicroSD card, then insert the MicroSD Card into the Tablet and when it asks to update, select Yes twice and it'll reboot and install the firmware for you

Nope did not work for me

I figured that as I tried the same method, but apparently, it doesn't work, So here's Method B:

1. Follow Everything from my Last Post up to the part for when you open the archive, but also download the RK29xxImageTools for extacting the update.img here and RKUtils (which will contain RKAndroidTool) here

2. Extract RK29xxImageTools into a Directory, (I did C:\RK29xxImageTools), Extract the RKAndroidTool folder from the RKUtils Archive into the RK29xxImageTools Directory as well, Same with extracting the update.img from Craig's Website, then rename update.img into wendal.img

3. Run the "runme.bat" File in the RK29xxImageTools folder, press 1 for "Unpack" and let it do it's thing, after it's done, the extracted files we'll need is in the "Temp/Image" Folder

4. Turn off the Tablet and put it into Bootloader mode (i.e. Holding only the ESC Button for a few sec., then plugging in the USB Cable) and load RK29Update from the RKAndroidTool Folder, if you did Bootloader mode right, RK29Update will detect the tablet correctly

5. Now with RKAndroidTool, Tick the "Misc, Kernel, Boot, Recovery and System" boxes and browse for each component in the "Temp/Image" Folder, then tick on the Loader box and browse for the file in Temp "RK29xxLoader(L)_V2.08" and select it as you did the other components, also Tick the Parameter box and in the Temp folder, select the file named "parameter"

6. Press the Erase IDB Button to format the Tablet, Then Press Execute and let the Tool do it's thing, for when it's done, it'll reboot and it should reinstall the Original OS

Hope that Helps
