hi how u jumper it? not more photos ?

i have iphone 4s give error -1

plzzzzzzzz

baseband chip is the damage.

try reball or change

not all do this will be done.

just depend upon your hand carry the gadget that you use.

How did you actually do the jumper? What do I need to do it? And how do I do it.

Thanks

since not long to jumper, just jumper by lead only use sharp soldering iron. the missing parts is small resistor only

Will this work on any resistor?

I have a similar problem.
Missing FL9_RF, C107_RF and C59_RF.

Tried to jump with no sucess, any other possibilites?

Still just searching.

Im sure somebody will chime in.

Is the phone u speak of gsm or cdma?

Its a GSM iPhone 4S

I saw the schematics for this components an instead of jump the pads I grounded the components before them on the chain

Someone with a different suggestion?

Thanks boknoy for that thread, it really helped!
Got iphone 4S with same problem, though my mainboard wasn't that messed up.
My problem was that FL2_RF was loose and was pushed against C79_RF, so I managed to fix it and got signal.
Unfortunately it lasted only 2 weeks and then again "Searching" and "No Signal" appeared. So I took it apart again but everything seemed fine, no short circuits or missing grounds. So I put it together again and finally managed to contact emergency service, with that, phone had signal again. That one lasted for 2 days, then again no signal.
Both times this happened was while phone was charging, don't know if these thing are tied or just luck.
Did I missed something? I have run out of ideas what may cause this?
I really would appreciate some help.

I would also attach image of details what i soldered, but I can't post links or attach image..

Thanks A Lot My Problem has solved
