First of all, thank you for the great job you do to improve nikon cameras!

I don't know if this thread is the right place for this, feel free to move this post in the appropriate section.

I have a problem on the D610, related to the "true dark curent" patch. The problem is very reproductible and is present with both patches tested (I'm not calling it a bug, but it looks like it).
I tested the menu based patch with the online tool (FW uptade using patched D610_0101 firmware) and the USB tool DarkCurentEnabler (found here: viewtopic.php?f=2&t=2319#p16478), and the problem is the exactly the same with both hacks.

Here is the problem:
when dark curent is enabled (via USB or via menu), after 8 shots, the camera freezes, no button has any effect, even the power switch doesn't turn the camera off (I waited for 5 min just to see if it was really frozen). I have to remove the battery to power down the camera.
On reboot, everything is back to normal (and dark curent is off naturally)

of course, I tried different metering off timer (from 1 min to infinity), and I changed every menu I could. The only change that had an effect was changing from 14 to 12 bits, but the effect was "corrupted images" (1 sec exposure with a quarter of the picture burnt while the rest is bright magenta with vertical white bands)... and the 8 shots limitation was still here.
This "freeze" happens when the camera is triggered from release button, internal intervallometer and external intervallometer (shutter speed tested: 1/4000, 1/50, 10", 30" and 1 min with external trigger). In burst mode, at 1/4000 I can shoot the full 14 frame burst, but if I shoot 3 by 3, as soon as the camera has recorded 8 pictures, it freezes.

Is this a known issue? Did anyone encounter this behaviour before? (mybe it's related to my camera...)
Have I done something wrong?
Is there a special setting to do apart from the long metering timer?
Is there any hope of fixing this, or should I sell my D610 and buy a D600 to get a good astrophotograpy camera?

thank you!

I found the solution to my problem:

The "image review" in the plaback menu was set ON... By deactivating this option, the patch (USB and menu based) works perfectly on a D610.

This trick should be documented, I'm sure that I'm not the only noob that will fall into this trap.

For those who encounter the same issue (camera freezing when true dark curent activated): deactivate image review, and don't check your shots more than 7 times once "true dark curent" is enabled !

A big thank you to the whole nickonhacker team, you do a fantastic job !!
