I don't have a working g7 anymore, so don't ask me for updates, because there won't be updates by me unless I can get another device.INTRODUCTION:
The purpose of this firmware is to provide a firmware just with the essential apps and tools needed for gaming, with no bloatware applications. It also includes several fixes to make system more stable and usable.

FEATURES:
Rooted with superSU
Google Play full compatibility (device spoofed as Samsung Galaxy S3)
Init.d support for manual scripts (you can add scripts that you want to be run in init)
Stock AOSP launcher
No bloatware or chinese applications. Only apps added are Tincore Keymapper, Tincore Quickflasher, and CIFS Manager. They are all installed in userspace area so they can be removed easily in case you don't like them. You will need to install your own emulators from google play store.
Stock mapper is compatible now. Tincore keymapper is also include if you need advanced features.
Compiled using AOSP and latest RKSDK patches in the framework
Oveclocked kernel to 1,6 ghz as optional patch (see above for further instructions)
New kernel compiled from scratch with following features:
- Joystick driver changes. Renamed to G7-GAMEPAD and solving some minor issues with a couple of games.
Vsync video playback fixed: Video playback is smooth now.
CIFS/NFS support
Mali, HDMI, wifi new drivers

In order to install the firmware you need RK Batch Tool in your PC included in the rar package.
Open Batch tool and select the Legacy_XX image file (.img).
With GPD power off, just connect it via USB Cable to PC. Then just press and Hold Volume + button and Press Power. RK Batch Tool will detect device, and you'll see the number 1 with a green box. If you see with a pink box, just select Switch Button until you see it in green. If the system ask you for some drivers, then just use the one included in the Batch Tool (or using driverInstaller package to install rockchip USB drivers).
Once device is detected with a green BOX, just select Restore and wait patiently while firmware is written.
Device will auto reboot to recovery and format your partitions. Just wait patiently until all process is done, since it's a long process and first boot can take several minutes, so just wait until it finishes and you see the home Android launcher.
PATCHES:
We have included several patches in the rar than can be flashed via Quickflasher. Just copy them to mnt/sdcard/quickflasher. Patches are the following:
Kernel Overclocked: Is the kernel included in the rom but overclocked to 1,6 ghz
Kernel_standard: The kernel that comes by default with this firmware, in case you need to re-install it.
You can check this video to see how to install a kernel or patch by using Quickflasher.
GENERAL TIPS and CONSIDERATIONS:
Default CPU governor (interactive) and I/O Scheduler are pretty conservative. For very demanding applications like PPSSPP or Reicast I suggest using ondemand CPU governor and deadline I/O scheduler. You can control this by using a CPU app like SETCPU, NoFrillsCPU, CPU tuner, etc...
If something (an app or game) is not working, send me a logcat to see what's going on. All complaints just saying ?This app game doesn't work? without a logcat will be ignored. And of course apps should be legally obtained. If your get an game or app from unofficial sources and does not work, then buy it and try again.
If you want to make your microSD as primary sdcard, just go to settings/storage and select micro SD as primary sdcard. This will swap internal and external memory. Then power off and next boot memories will be swapped.
THANKS:
To GPD for their support and collaboration.
