How to hack the Panasonic GH2 (w / Hack Pack)

Vitaliy Kiselev hacked the GH1 back in its day to well exceeds it’s software / firmware limitations and earlier this year he has managed to crack the encryption on the GH2. Why would you want to hack the GH2? It does look great under stock settings as it is but if you consider the hack enables the ability to film more detail and resolution, especially for film, there is a lot to gain from the boost in quality. Shadows can be pulled in post better (dynamic range) and over all resolvable image is increased (closer to film detail) among many other useful features such as improved audio

*Mac users are getting a “.cpgz” added to the firmware file name after the .bin. The correct extension for the firmware is .bin, that is what the camera looks for, fix that before trying to load it in camera.
*Keep in mind you can use the patches from the patch pack instead of the one included by just dropping them in the same folder. Their respective letters will light up and you can just click those instead.
Neumannfilms has made a Video tutorial featuring an in depth screen capture on how to download and install my hack and patch packs to get started using the Ptool Software (included). If you find my written instructions difficult, they make you nervous or you simply prefer to learn things visually. The screen capture will walk you through OSGFilms.com and show you how to download and install everything!
Recommended Basic set up for hacking : Body only, 20mm 1.7 Lumix lens, 64gig Sandisk 45mbs, & Extra Battery:
The 32gig (45mbs) Sandisk card will get the job done but as you use higher quality patches you will notice your recording time is going to go down considerably somtimes down to even 30min or less. If you need the extra time go for the 64gig (45mbs). I would say just shell out the extra cash for the 64gig because sooner or later you will want to film with the top notch patches.
