Sony Xperia M2 - Factory Reset

[Ant212]

I have gotten my phone unlocked and I was wondering if i factory resetted it would that cause the phone to be locked again to only one carrier?

How was it unlocked - You can check if it would relock by dialing *#*#7378423#*#* then going to Service info then SIM lock and if it says [ ] some text then 0 then it has been factory sim unlocked if it says [x] some txt then a number from 0 to 5 then yes it will relock or in my experience it will relock

It says

[] Network    0 

and the rest of the details are similar so does that mean it has been factory sim unlocked then

Yes you should be able to perform a reset or update or even repair without it been relocked as those details are the same as mine - Normally using a serial key or network unlock key is a factory unlock where as some of these stalls claim to unlock your phone but have simply on some occasions modified the network code which is you did a factory reset would reset this code
