Member: 1709786 Status: Offline Thanks Meter: 0 | just a quick question... What is the best way to remove the soldered metall shielding on iphone 4? (the one which you can't remove and is covered with the heatsticker) i used to cut it if i had to replace little stuff like the backlight coil but i think if i have to remove it completely i should replace it... After the Phone is fixed do you replace it? Do you just unsolder/resolder it? btw backlight issues on iphone4 CAN be solved by changing the lcd... just got the proof... Thx for your advice |

you are missing the two 3GS 3G coils get new coil replacements also your signal cable holder is also look messed up, you might want to change that too if you cant keep the 3G cable in place. here is the picture of the coil on youtube iPhone 3GS repair kit for No Signal GSM, weak signal or low bars CyberDoctorMD.com.avi - YouTube | |
