bought a device that has been blocked by T-Mobile
My country(Pakistan) does not have 4g yet so samsung did not officially release the 4g model. However, as I read a lot about how much the 4g version is better than the regular version, I decided to get one even if it meant no warranty.
I looked around the local markets and found only the t-mobile version available. I asked the retailer about it and he insisted that it is factory unlocked. I bought it and had to leave the country for 2 weeks.
So here I am in a foreign country with my new phone. I buy an internet sim card and use the 4g network. It works fine. I find out my phone has supersu installed. This makes me suspicious. Out of curiosity, I check t-mobiles imei check service. Turns out my device has been blocked by t-mobile. I can only guess it has been unlocked through software.
Other than this, the phone seems to be working great. It looks brand new with box/original accessories et al. In my one and a half week of usage, it seems to be working fine too. Only problem I found was that upon trying to update, I got the message that it was unable to do that because my software has been modified.
Once I return to my country, I will definitely have a word with the retailer, however the chances of him accepting and returning the phone are slim. Chances are, I'm stuck with the device.
My question, how bad of a position am I in? Will I be unable to flash future updates even manually? Is there risk that I could lose the software unlock?
I ask this because even if the retailer returns the device(1% chance), I will still need to go through the trouble of looking for another device. And as I said, this one seems to have no other defect. The silverlining though, is that this device came rooted...which saves me the trouble to do it myself.
Please guide me as to what my best course of action would be.
Thank you in advance =)
