GSM connection issues after battery replacement
I recently repaired my broken/constantly depleting iPhone 4 battery using this iPhone 4 Battery Replacement instruction. After exchanging the parts and not touching anything with my bare hands I reassembled the device. Afterwards I had a pretty bad reception but it was manageable.
Following the tip to degrease the connecting parts with a degreaser such as Windex, I got my self a window cleaner, sprayed it on a towel made sure it is just a little bit wet and swiped it over the connection points (of the pressure contact). Now I don't have any reception.
Is there anything else I can try to improve my reception. Did I use to few of the degreaser or is it possible that it left some "protective" coat on top of the metal. If so is there a possibility to get it off?
I didn't touch anything else. Wifi and GPS works fine.
I hope you can give me some advise!
Is this a good question?
