Member: 397838 Status: Offline Thanks Meter: 0 | Iphone 3g Wierd Siganl Problem HELP. I currently have an i hpnoe 3g 8 gig. I mistakenly updated to os 4.1 to which i had loads of problems ( no news here ). So i downgraded back to 3.1.3 but stuck with baseband 5.14.02 everything fine untill 2 days ago when my phone suddenly showed no service.I rebooted the phone and voila signal returned for a few minutes. I then found when i went outside i had full 3g signal everything working fine. But when i went indoors the phone signal drooped then started searching then no service. I rang o2 for service status that was fine. Tested other sim cards same problem. I have read the articles here and on the web regarding signal issues and have taken phone appart to see if i have a broken logic board or damaged antenna etc but found no problems even with microscope. I rang apple they said update the firmware, As this seems like a software issue. So i put 4.1 back in and still got the same problem. I am reluctant to go to os 4.2 at this moment. i also emailed iphone repair centre with the reply to update os as no technical reason for this problem ? so before i bite the bullet maybe there is a Genious amongst you good people who can shed some light. P.S jailbroken using sn0wbreeze. Phone is officialy unlocked. |

Member: 397838 Status: Offline Thanks Meter: 0 | Hi thank you i have read this post but i dont think this applies to my situation as i have dismanteled the phone and cant find any parts missing or cracks etc.Alo i have tesed the coil using a mulitmeter and getting open circuit but i cannot test proerly as i dont thik the ohms range goes low enough. I have an apointment with the Genious bar tomorrow if they cant help then that solution may be the answer. If apple say its harware then i will give it a go as i will have nothing to lose. I will try using condutive paint from Halfords as i have found this to brilliant for fixing circuit tracks in the past. Thank you for the response. |
