No signal after changing battery on iPhone 3GS
My 3GS was shutting off whenever it dropped to 60-70% battery life for a few months. I'd have to plug it in to reboot and then after a few minutes it would tell me I had < 5% charge or whatnot. It got worse and would die constantly in the 95% range, but would still reboot sometimes with some battery left, but usually only successfully if I was plugged in. So I figured it would be cheap/easy to try to replace the battery on it.
I, regrettably, tore into the thing pretty aggressively and cannot get a carrier signal at all after reassembling it. At one point, I was able to occasionally get a single bar of service for a matter of a couple seconds, but for the most part, just no service at all. Now I can't even get that much.
In the numerous attempts to reassemble, I seem to have messed up ribbons 6 and 7. They won't stay connected, which is why I have the soldered wires shown here http://i1211.photobucket.com/albums/cc42... (the left one and the lower right one connect the ribbon to the terminals).
I'm sure that ribbon 6 is the least of my worries, though my wifi only works within 2 rooms from the router and I don't think my GPS is working, or camera for that matter, but I'm most concerned about getting my carrier signal back. So this picture illustrates what I currently have setup around ribbon 7 http://i1211.photobucket.com/albums/cc42.... You can see the wire on the right connects the ribbon to the terminal. The other wire was something I just added in a futile attempt which attempts to bridge the antenna (which is also terminal 7, right?) to the tab that forks up to connect to the bezel.
I'm at a loss as to what to try. I've made sure the 2 tabs make a good connection to the bezel casing and also from what I can tell, the two inductors next to the antenna (where ribbon 7 connects?) seem to still be in place, The extra wire was an attempt to try to bypass those in case I screwed them up, based on what I read in http://www.mauron.net/iphonerepair/ which seems to be more focused on the 3G model.
Can anyone provide some help on what to try? Or have I tinkered too much that all hope is lost? I can provide additional photos if needed.
Thanks so much!
Updated with photos of trying to solder the resistors and traces as suggested:
Resistors round 2 (removed solder and resistors came out doing so): http://s1211.photobucket.com/albums/cc42...
Is this a good question?
