when i turn on phone, i get no signal, rarely i get a signal and 1 "unit" of signal maximum, i have tried diffrent sim card.
Before opening i didnt have that problem. I opened it manually, i repaired "thing" where you put in headphones and battery charger. Could i have damaged something?
Make sure the two gold colored contacts (on the underside of the antenna / bottom part of the picture) contact the motherboard properly. Also check to see if you've damaged the antenna contacts on the motherboard (they should be flexible gold plated metal as well). Good luck,
