MHL problem

Jan 22, 2013
Today i got MHL adapter from dx. I tried it on my mi2 and everything was working well. Then I disconnected the plug and tried my girlfriend's i9100. I didn't work with s2 so I taught there must be a compatibility issue between adapter and s2 rom. Then I connected my mi2 again and nothing happened. My TV doesn't recognize my phone anymore. Is it possible that connecting the adapter to other phone broke it? It makes no sense.
