Network with different firmware versions

[Freemann]

I bought on the internet a set of Circle's and these circles have a different FWversion.
My "own" circle's have version 27-6-2011 XX:XX:XX and the secondhand circle's have version 13-5-2011 XX:XX:XX

i'v search on the internet how i could update these circle's. i find some info about the UpdateWizard, but it's not working
The wizard keeps saying that there are no plugs to update.

Has anybody a idea/experience with this problem and how to solve it?

27-6-2011 is a FW version for new plugs from the factory. As this is a minor fix you are not able to upgrade from 13-5-2011 27-6-2011.

If you have an older FW vesion an upgrade to 27-6-2011 will be performed,

ok, good answer. Isn't possible to update through a DB "hack" (change some firmware version values)?

I didn't saw the firmware difference until i was playing with PHP.

1 plug gave a power usage of -16xxx,xx Watt. After some searching the only difference that i found was the firmware version.

The thing that (probably) cause the -16000 watt, is a GainB of -8,000xxxxxxx (where this value is normally between -0.xxx -3.xxxx).

question 1:
I'm a wrong with this gainB -8,000xxxxx value ??
question 2:
is it possible to (hard)recalibrate a circle?

It might be just a correct calibration value, not quite sure what the ranges are.
The circle's are factory calibrated so there's no way to recalibrate!
