Pls help me. I maybe bought faulty HTC One X.
So this is the story.
I have a friend who went on a vacation from Croatia to the UK. In the UK, he bought the HTc One X there, locked on o2 network. He sold that device to me, and he told me that i can unlock the device by purchasing unlock code from eBay. I purchased several codes, but i keep getting error - incorrect password.
I really have no choice, i cant sell that device to anybody, neither i can use it on Croatian networks.
Also, i have made factory reset, but it seems that neither this helps me.
Also, when i try to update software to 4.2.2, in middle of installation red exclamation mark shows up, then phone reboots. Please help me.
Device is not rooted, has stock recovery installed, bootloader is relocked, and stock 4.1.1 is installed.
Is there any other method of unlocking the device except entering the unlock code.
Thanks in advance
