Hi. I've bought a used GH2 recently for a 3 camera shooting project. At first, there wasn't any trouble. But I found out that the the camera couldn't record videos longer than 90 mins ar HBR mode, 1980i, 24p. After asking around, I've downloaded and installed a hacked firmware from this page and changing some values of the :

Which solved the recording issue, but other issues appeared as well.

1- I can't record a video at "Manual" mode (in the "Creative Movie" menu) higher than 720p. At 1980i, when I check the video (after recording, it says "Read Error. Please Check the card". I've been using a Lexar 64gb SDXD Class 10 90mb/s without trouble for a year now. I tryed a Sandisc Extreme pro 32 gb 95 mb/s, same problem. I tried factory reset the cam and even reinstall the original Panasoic firmware, no luck. I tryed the same cards on my G6 with the same recording properties, no problem.

2- I can't record a video at "HBR" mode (in the "Creative Movie" menu) or even adjust it in any way whatever the image format( 720p of 1980i). When I check the video (after recording, it says "Read Error. Please Check the card". I've been using a Lexar 64gb SDXD Class 10 90mb/s without trouble for a year now. I tryed a Sandisc Extreme pro 32 gb 95 mb/s, same problem. I tried factory reset the cam and even reinstall the original Panasoic firmware, no luck. I tryed the same cards on my G6 with the same recording properties, no problem.

Any idea & solution to this ?

Thanks to answer

*****UPDATE: Problem solved. the reinstallation of the original firmware with the protool re-work (no hack) did the trick. The seller should have told me that the camera was hacked, it would have be less painful.
