S7800B SUPERCHARGED v2.2.1 is out !!! This is a customized version of JXD's Stock Firmware v1.1.4 with several
fixes, enhances, loads of useful applications, and a selection of overclocked kernels. Finally fixed the issue with the other batch of s7800Bs not overclocking above 1,200 Mhz.
SUPERCHARGED v2.2.1 - CWM UPDATE 2013/12/27 URGENT FIX !!!- Removed overclocked kernel update from CWM to avoid soft bricking. Some s7800B1.4 users have reported
soft bricking due to severe instability resulting from overclocked speeds. If you have managed to soft brick
your device, reboot to bootloader mode by using a pin to click the "Reset" button and pressing the "Volume Up"
button at the same time. RKbatchTool should detect your device. Choose the stock kernel image and install by
clicking "Upgrade".- Fixed voltage regulation spikes, reduces reboots upon device wake-up for unstable devices.
- Deactivated cellular radio and GSM software, less power consumption.
- Stock Jellybean boot animation.
- All SUPERCHARGED v2.1 fixes included.

--------- NEW OVERCLOCKED KERNEL ---------> Requires RKbatchTool to install.- Overclocked speeds now visible and active on s7800B1.4 devices.
- New kernel supports initial and current batches of s7800Bs.
(Thanks to JXD)
- Please see the "PRESET OVERCLOCKED KERNELS" section for overclocked kernels instructions & links.

PRESET OVERCLOCKED KERNELS: Updated !!!
For use with RKbatchTool Only !!! _____________________________________________________________________________________
The latest S7800B SUPERCHARGED v2.2 rom update comes with an overclocked kernel capped at 1,800 Mhz.
Some of you have requested lower caps, while others have requested the original stock speeds.
After downloading and extracting "Overclocked Kernels.zip (19.57 MB)", you will find the following files:
Kernel_OC_1608mhz_DuelMode.img -> Top speed capped at 1,608 Mhz - Stable
Kernel_OC_1704mhz_DuelMode.img -> Top speed capped at 1,704 Mhz - Stable
Kernel_OC_1800mhz_DuelMode.img -> Top speed capped at 1,800 Mhz - Stable
Kernel_OC_1920mhz_DuelMode.img -> Top speed capped at 1,920 Mhz - Experimental
Kernel_StockSpeeds.img -> Top speed capped at 1,608Mhz + all stock speeds - Stable
After completing the v2.2 update procedure above, run the RKbatchTool again, this time select the kernel you
wish to install by browsing to the "Overclocked Kernels.zip" unpacked folder. Click the "Switch" button to go into
bootloader mode, once the number 1 box goes "Green", click "Upgrade" to install the desired Kernel. This will
only update the Kernel portion of your rom and will not erase or wipe your Rom or data :-) After the kernel is
installed, the system will reboot using the kernel you chose while leaving your data and rom intact.

Your early Christmas gift is here !!! S7800B SUPERCHARGED v2.0 This is a customized version of JXD's Stock Firmware v1.1.4 with several fixes, enhances, loads of useful applications, and a selection of overclocked kernels.
SUPERCHARGED v2.0 BASE( A installé avant d'installer l'update 2.1)- Modified Google Play Market to support "All DPI" apps - No more app DPI restrictions in Play Market.
- Modified Build.prop to simulate Galaxy Note 2 ID - More apps are accessible in Play Market.
- Modified Google Services Framework to emulate Exynos 4xxx series - More apps than Rockchip.
- Fixed External SD card visibility and accessibility.
- Replaced stock launcher with a stable alternative.
- Replaced stock recovery with Androtab's CWM recovery for rockchip devices.
Future updates, fixes, and patches will not require full system wipes.
- Rom will no longer automatically wipe memory contents after upgrading.
- Updated included apps.
- Added a new cool boot animation :-)
- Customized kernels with different speed caps to choose from.
Additional Notes:- This version mounts your Micro SD as internal NAND (SDCARD).

THE STEPS BELOW !!! FAILURE TO DO SO WILL LEAD TO
UNEXPECTED RESULTS !!!_____________________________________________________________________________________
Traduction FR ICI
(Merci a Luke_fr et à ceux qui l'ont aidé)_____________________________________________________________________________________
Important Notes:- This version mounts your Micro SD as internal NAND (SDCARD).
- Before upgrading to this version, remove your MicroSD to protect its contents from getting formatted.
- The upgrade process will take longer than usual. This is normal as re-partitioning NAND takes time.
- This is a major release and will wipe your device. Backup important files to MicroSD before proceeding.- Future updates/fixes will not require a full system wipe unless absolutely necessary.
Please follow the steps below: - This is a one time procedure. You will not need to repeat it again.
1. Download S7800B_SUPERCHARGED_v2.0_OC_Reparted_Ext2Int _CWM_MrktFix.zip from the link below.
2. Extract zip, you will find three folders, "RKbatchTool", "Firmware Image", and "Overclocked kernels".
3. REMOVE YOUR MICRO-SD FROM YOUR DEVICE !!! MAKE SURE YOUR DEVICE IS FULLY CHARGED !!!
4. Open the RKbatchTool and select the update.img from the "Firmware Image" folder.
5. Connect your device and click "Switch" on the RKbatchTool.
6. Once the number 1 box turns green, click "Upgrade". Process will take longer than usual.
7. After upgrade is complete, system will reboot to CWM-Recovery. Close the RKbatchTool. Rom updates will no
longer result in automatic wiping of data.
8. To navigate through the recovery menu, use the "Volume UP" and Volume DOWN" buttons to scroll through the
selections and the "Power Button" to click your selection.
9. IF YOU HAVE NOT REMOVED YOUR MICRO-SD, DO IT NOW !!!
10. Select "wipe data/factory reset". You will be presented with a confirmation menu, select "Yes". This will
attempt to wipe your device. This will take some time and you may be presented with errors at the bottom
of the screen, simply ignore them.
11. Now we need to fix your internal 1.07GB of storage which will later be mounted as your External SD. Go
to "mounts and storage", select it, then select "mount USB storage". This will mount your internal
storage as a USB Storage Device in Windows. Windows will detect an unformated drive and will give you
the option to format it. Please format the newly detected drive using the fat32 disk format. By doing this,
you are activating the newly partitioned 1.07GB internal storage which was not visible in the previous
SUPERCHARGED version.
12. Once Windows completes formating the drive, go back to your your device and select "Unmount".
Then select "format /sdcard" -> "Yes"
13. Scroll to and select "+++++Go Back+++++", then again, go to "wipe data/factory reset" and select it.
-> "Yes" to wipe device again.
14. After the wipe is complete, scroll to and select "reboot system now". CWM will detect an error with root su
access and will offer to fix it, select "Yes". System will then reboot. Be patient.
15. 1st reboot will take approx 5 mins. Once that is done, leave the device for another 5 mins as hardware ID
is being changed to Exynos 4xxx series. During this process, several apps will request SuperSU for root
access, simply grant them access and leave the device to run.
16. After the 5 minutes are over, your device is now SUPERCHARGED !!! Shutdown your device.
Insert your Micro-SD card. Then switch on your device again. Your device is now ready :-)

EXPERIMENTAL OVERCLOCKED KERNELS:_____________________________________________________________________________________
Exactly what the title says... These are experimental kernels used for testing purposes only. Use at your
own risk !!!
OC_1800Mhz_kernel_MODv0.1.img (11.44 MB)
http://www.multiupload.nl/THNOZA5MN9To all those that have been experiencing capped speeds below the reported maximum, please try
the experimental kernel attached above. I've made some modifications to trigger a different
behavior from the ACT8846. Just download the img and flash it using RKbatchTool. Please report
back with your findings.
_____________________________________________________________________________________
This is not an official release. It is a modified version of Stock FW 1.1.4. If for whatever reason, the image fails on your device, just flash the original JXD firmware v1.1.4 to restore capped speeds and normal operation.
ALWAYS MAKE SURE YOUR DEVICE IS FULLY CHARGED BEFORE YOU FLASH ANY FIRMWARE IMAGESAs always, your kind feedback is always appreciated to make this ROM better and faster.
