Hi,
try first hard reset your mobile and try again

[Octopus box]

Try to re-flash the phone with another firmware, make Factory data reset and wipe cache partition and perfrom steps 1-11, which I have written above, again. When phone's info will be read out correctly from the "Main" tab in the Software, write QCN.

i did wipe the cache and factory reset still the same

[Octopus box]

Connect the phone directly to PC and try to perform "Read Info" operation from "Main" tab of the Software on different COM ports, with enabled "Manual Select" option.

I really don't think has anything to do with it... but thanks....I think there could be something with the DIAG connection on the phone maybe something similar to whats going on with the S5 with lollipop that you have to select in recovery mode in order for the DIAG to work. This phone has 4.4.4 Kitkat and does not have that in the recovery....
