I bought an unlock code from ebay a few mnonths back for a HTC One (which was working fine on EE) and it worked for a few weeks but then it wouldn't boot up, it got stuck on some kind of restart screen where you had few options to safe boot, restart, quick start.
Was this to do with it been unlocked??
Im wanting to buy a Note4 second hand but its on O2 and will need to unlock it but dont want the same thing to happen.
The issue is not if the phone is unlock, is you bought it from ebay.
I didnt buy the phone from ebay I already had it working fine on EE. I purchased a unlock code from ebay which worked then a few weeks later the phone stopped working - it had been working on EE for years before fine
