Panasonic GH2 is a mobile video beast: hackable and extendable.

The Panasonic GH2 turns out to be the currently best Video-DSLr out there, although it is not even a DSLR. The micro-four thirds sensor is much smaller than a full-frame sensor, but the video footage that this great camera produces is far superior to those from lets say the Canon EOS 5D MKII - no moires, no aliasing and a much better video codec: AVCHD. Besides the obvious facts, the GH2 gets hacked extensively: Vitaliy Kiselev first hacked the GH1 and after that the Panasonic GH2.

With the PTOOL firmware manipulation tool, you can get the following improvements, among many others:

- Change Video Bitrates
- Improved GOP patches.
- Improved MJPEG size patches.
- change the 30min recording restriction
- lots of other changes

Patching the firware was possible, after a GH2 Firmware update leaked.

Here is a short overview on what to do in 10 steps:

1) Get a Patch from the extensive patch repository.
2) Load the GH2 1.0E firmware
3) Check all necessary patches, Version increment must be always checked.
4) Save firmware. Just change last digit to any number you want. (e.g. GH2__V11.bin)
5) Copy firmware to root of SD card. Fully charge you battery. Do not even attempt to use AC coupler!
6) Power off your camera if it was on.
7) Power on camera. After this press (not hold) green play button.
8) You'll see hourglass and prompt to update.
9) Press down arrow and after this Menu/set.
10) Wait until upgrade will be completed.

happy modding!
