I have a DMP 4305g running on firmware 5.2.1 and DMM 5.3 !
So i understood that we have to upgrade the firmware of DMP to 5.3 version.
Shall i directly upgrade 5.2.1 -> 5.3 or
I have to go for 5.2.3 as a upgradation path. Honestly i am not able to find any upgradation path for DMP .
My issue got resolved.
The upgradation path is 5.2.1 > 5.2.3 >5.3
Now its working perfect.
