Author Topic: [30.08.2014][ROM] JXD S7800B 8GB - CyanogenMod 11 Kitkat (With Power/Sleep fix)  (Read 14335 times)

GRiM (OP)

Thought I would give people a heads up in case some wasn't aware about the beta of a ported CM11 rom.   Seems great so far  :)

ROM Download:
http://www.arctablet.com/blog/forum/crewrktablets-rk3188-entwicklung-customroms-development-croms/jxd-s7800b-gamepad-8gb-kitkat-cyanogenmod-11-rom/

Rom Installation:
1. Download Rockchip Batch Tool 1.7: http://www.cloudstor.es/file/m1_OTM0OA/
2. Connect your S7800B to your computer via USB 2.0 (avoid USB 3.0 ports).
3. Power up your device and run the file RKBatchTool.exe (requires administrator) on your computer.
4. You'll note the tool shows a pink color indicating the status (device is connected).
5. Click the "Switch" button and your device will reboot. Install drivers via Device Manager.
6. Press the "Reset" button your device, wait for it to boot up.
7. Again, click the "Switch" button, this time the area above will turn green - programming mode ready (if it doesn't you didn't install the driver).
8. Select the desired flash image file (.img) and press "Restore".


Power Button/Sleep Fix (RK3188-T users):
For those people who have the power button/sleep bug in most custom roms (RK3188-T users) you will also need to flash the extracted kernel.img from Webclaws 2G/SPECIAL rom.

Kernel.img/Flash tool:

New kernel.img and instructions: http://boards.dingoonity.org/jxd-devices/the-fixed-stock-kernels/msg115267/#msg115267

Thanks for sharing. Could you give us a run down of what seems to work as it should and what doesn't?

CyanogenMod generally does a good job. I'm kind of reluctant to upgrade, because I'm pretty satisfied with WebClaw's firmware 2.0 - but once I'm done with my IRL business I'm sure to check it up and write my thoughts about it.

I haven't had time to use it much yet but from what I have it seems to run really smooth.   Initially after installation/kernel flash the touch seemed to be really unstable and assumed it was because of incompatible kernel, however after a couple of reboots it was fine.  The addition of CWM recovery is also a big plus :)


I'll let you know if I come across any issues.

Here is benchmark..

It would be good to mention that by upgrading to a Kitkat based ROM, you will loose the ability to swap the external SD with internal SD. Only option available would be folder mount.

Most of the JXD users prefer swapping to get more space for apps/etc (after increasing the app partition size using a modified parameter file).

Or you can use something like this..

Does this have the built in onscreen to  joystick/gamepad mapper like the stock roms, or do you have to use a 3rd party app like tincore?

No this doesnt come with the original keymapper,  You will  need to use tincore etc.

You're using S7300B.
This firmware is for the S7800B.

If you will forcefully flash that firmware, it WILL brick your device. Do not attempt this.

He won't be able to brick it anyway. Amlogic devices cannot be flashed with Rockchip flash tool xD.

Indeed.  Double facepalm  :D

Plus,  many people seem to use the phrase "bricked" far too loosely nowadays.     For example I only consider a device "bricked" when you need to physically repair the device or use extra hardware to get into bootloader etc.

If a device simply wont boot to system but a reset button or key combo will get into bootloader to re-flash I do not consider that "bricked".
