GH1 hack no longer working on v1.3 cameras

It is true that the 1.34 firmware factory installed in the most recent cameras cannot be hacked at this time but it is not a fair conclusion to say that it was done to prevent hacking since the creation date on it is before the hack was invented or in the public eye.

You may be right but any date can be put in firmware...... ?

...maybe is that the hack can also be used to remove the block on using third party batteries? And it can be used to remove the time limitation on how long European cameras can be used to record video - I think Panasonic might get into trouble if they officially sanctioned the latter hack as I believe it contravines EU rules about what classes as a camera and what classes as a camcorder. This could be why Panasonic have quietly re-engineered the GH1 firmware so it is incompatible with the hack.

Apologies in advance but have you guys tried naming the hacked Ptool firmware GH1_ 135.bin or simply one number higher than whatever version firmware came in your GH1? That's two underscores before the 135, BTW, very important. When I first tried applying the hack to my GF1 I only used one underscore and couldn't understand why the camera didn't recognize it.

Also make sure your battery is fully charged. The Panas won't do a firmware update, even an official one, if they sense the battery is even mostly charged. Has to be topped off for the firmware to update.

I was told at focus on imageing in the UK it would be an upgrade like the G2. Now that may or may not be the case but I'm expecting touch screen etc but nothing over exciting. They have already announced their higher end video camera to take the current DSLR lens line up. 2+2 doesn't always make four when I make assumptions. david

This hack has done more to boost the reputation of the GH1 than Panasonic could dream of... locking the cameras is dumb dumb dumb. :x

I'd love to see you make that case.

Yes, the hack has certainly promoted the GH1 among a niche. I happen to be in that niche and love the hack. But Panasonic caters to a much larger overall market. It seems perfectly reasonable to speculate that the GH1 hack is hurting the marketability of the GH2 or even their full "made for video" m4/3s camera.

How it all shakes out as a net positive or net negative for Panasonic is anybody's guess. Protecting future cameras from hacking may be an important bottom line decision. Or it may be simply petty and stupid - or possibly some combination of the two. I don't think either you or I can know.

That seems unlikely. The hack project started in early April of this year and was making good progress in about two weeks. Within this timeframe the hack developer Vitaliy reported visits to his website from URLs that correspond to Panasonic and he speculated that Panasonic was now paying attention to what was going on.

Version 1.3 firmware was made available in early May and the hack project quickly moved to use this newer firmware as the basis of the project. So it seems fairly obvious that version 1.34 had to be created and implemented many weeks after the hack was well under way.

Why version 1.34 firmware might be hack resistant is anybody's guess. But it simply is not possible to dismiss the possibility that it is a reaction to the hack based on the sequence and timing of events.

If the GH2 turns out to be just a ober hacked GH1 its not gonna sell!

If its sensor is not better than the GH1 (ISO & or res) and it does not include electronic shutter why bother?

Possible reasons to bother:

Native 1080 24p unwrapped that doesn't freeze.
Full 1080 @ 60i

Better CODEC implementation that includes I, P and B frames instead of I & P frames only. Maybe even the option to use an advanced CODEC like AVC-Intra.
Higher supported bitrates in AVCHD and MJPEG
Better demosaicing and resampling routines.

Better crop modes that effectively turn the camera into a high resolution 2/3" camera when used.
Better audio control and support.
Better video support via zebra strip and other exposure assist tools.

Mind you, I'm not saying any of this will happen or is likely to happen. But these are things that could happen without major sensor upgrades of the kind you mentioned.
