This appears to have worked for my DS-2CD2732F-IS it is now running 5.4.5 :) I will try my DS-2CD2032-I tomorrow. Thanks for all the great work.
2CD2032-I update went fine as well
Just a quick update I have the camera back running V5.2.3 build 141024 it also ran V5.2.0 EN versions. It does not like V5.3.0.
I tried on the other camera and it has upgraded to 5.3.0 and then 5.4.5.
I have a couple of DS-2CD2732F-IS I would like to upgrade. One is 5.2.0 and one is 5.2.5 please let me know what needs to be done to upgrade these I have extracted the MTD5 and 6 blocks from both.
