S7800B FW v1.0.9 / CPU-1800mhz / GPU-798mhz / Alpha v0.2
It's finally here. This is a pure stock of v1.0.9 with an overclocked kernel. All other functionality is identical to original v1.0.9. Even broken root exists, which means you need to fix root upon installing firmware just like official v1.0.9.
WARNING !!! You are at risk of bricking your device should you choose to use the attached firmware & tools. You have been warned. You agree that any liability arising from the usage and/or sharing of the files below is strictly yours and may not be transferred to anyone else in this forum. Use at your own risk !!!
Alpha v0.2 Changes
- Reverted DDR2 Bus Speed back to 400 Mhz.
- Fixed voltage irregularities that caused hardware instability & battery drain.
Was able to run PPSSPP - God of War (Ghost of Sparta) @ full frame :-) and no system hangs. Would really appreciate your feedback to determine if this is the optimal combination for the s7800B.
Alpha v0.1 Changes:
- Overclocked CPU speed from 1,608 Mhz to 1,800 Mhz.
- Overclocked GPU speed from 600 Mhz to 798 Mhz.
- Overclocked DDR2 Bus Speed from 400 Mhz to 677 Mhz.
Side Effects:
- Massive power drain, battery would probably last for 2 hours after a full charge.
- Gradual heat up of unit as processor runs at overclocked speeds.
- Some have reported graphic glitches and system hangs. (Looking into it)
_____________________________________________________________________________________
Installation:
- Included RKbatchTool v1.7 with English Language Support.
- Included all necessary drivers.
- Simply follow the exact same steps to upgrade to JXD's Official Firmware to apply this firmware.
- You will need to Re-root after flashing firmware.
- Install SetCPU or MasterCPU to modify speeds.
This release is intended for testing purposes and is not an official release. It is still in alpha. If for whatever reason, the image fails on your device, just flash the original JXD firmware v1.0.9 to restore capped speeds and normal operation. Awaiting your valuable feedback to find a healthy balance between system speeds & hardware stability.
ALWAYS MAKE SURE YOUR DEVICE IS FULLY CHARGED BEFORE YOU FLASH ANY FIRMWARE IMAGES
