[Q] Region Lock issue : Help required topic

I purchased a Samsung galaxy Alpha from Singapore. It was mentioned on the box that the device needs to be activated with a local sim card and a 5 minute continuous call needs to be made so as to continue using it outside of South East Asia.

I did the same. On returning to India, I started using the cellphone with a Vodafone Network Service Provider.

After about 15 days of usage, the cell suddenly started asking for "Sim Network unlock Pin".

I contacted the Samsung service centre in India and they asked me to contact Singapore, who in turn asked me to contact Malaysia support saying the Country of Manufacture is Malaysia. Malaysia support has asked me to ship the mobile back to Malaysia, which is not possible for me.

Then I rooted my mobile and installed RegionLock Away, which says problem should be solved but the problem is still persisting.

I read in a post and dialling the said codes gave the following output

2. *#1234#
super user opened and asked to disable Samsung knox, which I did and then the following was displayed.

My question is What should I do to make my mobile phone operational.

I have also tried to dial in *#7465625#, which says 'not registered on network'.
