I bought a locked ATT and I did S-Off and unlocked bootloader to put the international developer edition ROM on it so I can get OTAs directly from HTC. That is fine and works completely well. I get updates directly from HTC. But I am in Canada now using Wind Mobile (same as T-mo in the US) but I'm "roaming" the whole time.
I tried using this unlock method:
and still it doesn't work. Its just on Wind Away network.
So I bought an unlock code and but I put in my wind mobile sim card, no menu comes up so that I can put in my unlock code...
Wind Mobile uses the same feq as Tmobile (I tried it with an S3 last year) so I should at least be able to make calls and texts.
PLEASE help! I'd greatly appreciated!!!!
