So took it to another shop, he repaired it in a minute and didn't take any charge either. Guess it was really a minor problem. Remember the
repair man story?
Really? Curious to know which method the man used?
Btw what you did I also did the same before so that I can find all things on my phone. But did not face any problem like this, fortunately. Now what I think it's better always keep the keys in the paper, and yes always there are in two places. So that if you lost one in anyway you can use the other one.
I have no idea what he did.
Had I not forgot the pattern, there would have been no problem. I have changed phones multiple times, this time problem arose only cause I forgot the lock.
