S6 Edge SM-G925F , Abnormal Behavior

Hey Guys , I recently purchased an S6 edge G925F from my local market , in used condition , it came with Android 5.1 Lolipop but when i upgraded it to marshmallow , its GSM capability stopped , which means that it detected my local network but failed to register on my sim network , it would say " could not connect , try later" , G925F roms work completely except sim communication , and when i had this issue , i took it to my seller to repair it , and he refreshed it to lollipop again and said that dont upgrade to marshmallow , because it has GSM bugs etc , and i asked him about what happened and asked that whether it was locked or etc , he answered that my phone got locked (i dont know if its carrier or bootloader or baseband lock) but he said it got locked due to baseband change , My questions are :
Q1. is this a reconditioned phone that was previously some carrier phone that they converted it to G925F ?
Q2. Do locks (network , carrier , baseband , etc) exist for G925F which would produce GSM issues ? like i had ? sim works but fails to register on gsm network
I will be glad if anyone could help me out! (P.S IMEI remained intact , didnt get corrupt, despite no network capability , and i checked , in my country it isnt flagged stolen or etc)
