Replaced Screen Now get Searching...

If you use iOS 6 try to set the correct time in settings and reboot before inserting SIM card. Let me know if this works please

Yes of course i tried to restore it, but in the installation restore my i tunes find an error, the error <-1>, so i have a situation now...

It seems to be a bug in iOS6 on 4S.

I've had the same problem and for me the sollution was to connect the phone to iTunes and when iTunes has found the phone you take out and insert the sim-card again. It might take a few tries.

Try that and report if it worked or not.

The "Searching" problem can be fixed by doing a restore. No big deal :)

I saw a blog about this and they said to check that date and time correct and then restart the phone. i would be interested to find out if this is the cause of this problem.

With the new update IOS6 yes there is a problem with the software. After i replaced a screen on a 4s that had this new update i too got the searching and after pulling the phone apart 4 more times i had no idea what eles to do.

So after the last time i put the phone together with the sim in and got the searching again I picked up my phone and called the mobile... Not sure why, but it worked and i then got reception.

I have repaired 5 phones since then with this IOS6 update and all of them had this searching and i just called the phone.

Hope this helps others.

Hope it make sence :)

Just call the mobile number on the phone that your fixing

just set time and date and the phone will do the rest...

Try dfu mode

Hi

This is the second time i have replaced my iphone screen. The first time i replaced it no problems worked straight away. I had an older firmware aswell.

The second time I had the exact same problems as everyone here... Just kept saying SEARCHING up on the top left of the screen, It didn't know if the sim card was in the phone or out. I took it all apart again and looked at every connection and they were all perfect.

I tried the date and time thing because i was desperate, and no surprise it didnt work either.

'''I updated to the latest firmware 6.0.1 (10a523) and the phone started and worked straight away.

'''

Hope this helps

did you all replace the ground clip connector when reinstalling your battery?

i didnt and lost it.

now my phone is completely bricked from trying to restore.

Unless you have physically damaged the phone, as in knocked the signal resistor or the blue coil off the board etc, I have found that if you turn the phone off, insert the SIM card, turn the phone on, go to settings and connect to wifi, return to the home screen, pop out the sim card, it should now recognise the SIM card by saying "no SIM card installed" put the card back in and it should pick up signal after a minute. It seems to be an iOS 6/6.0.1 glitch, or maybe something Apple put in to irritate independent repairers like myself. This works for me more often than not. Hope it helps Chase.

thnkx soooooooooooooooooooooo mch its works for me iphone4s

Hello everyone, i have exactly the same problem with Jeff, after the replacement of screen in my I phone 4s. It doesn't recognize the SIM card and also it appears as Searching on the top. How can i fix it? Anybody knows,

hay guys my problem was the date and time after screen replacing set the date manually if you put it on wifi it updates time itself so both sides work reason if date is to late will not connect to the network

There is atiny black resistor next to the charging port flex cable. Right below the 7 gold dots. Very easy to know off. Underneath the resistor is 6 very small points. If that was to fall off upon removing the cable, it will not read a sim.

also if it is reading sim card, but still "searching" or "no service" (sometimes switches back and forth) the small blue resistor may have been been detached. Or the smaller resistor next to it. Both are located by the signal cable (which is connected to the loud speaker) may need a new motherboard.

Somebody opened up this rather old question :-) anyhow, now matter which OS and no matter what trick one tries, if the part is missing, it will not work. The missing piece pointed out by the OP is part of the BASEBAND circuitry. It is a 74AUP1G08 Low-power 2-input AND gate 74AUP1G08 (not a resistor or capacitors or anything else ;-). It is available at places like Mouser.com. Part number 771-AUP1G08GF132

Hi,

I have the same problem as above, I have just changed my 4s screen and now it is always searching. However i am on IOS 7.03. Does anyone know of any ways to resolve this?

make sure you replace the grounding clip, the little part that fits in with the battery screw down. that will cause your phone to search and will eventually brick.

I had same problem with bluegrass cellular (CMDA) phone that doesn't use a sim In the sim slot. I put at&t one in it and it said invalid sims and then I removed it and it searched a minute and finally found bluegrass towers and works fine now. CRAZY!!! But it worked.

Hello everyone!

I have replaced a complete motherboard because my phone was damaged by falling off my jacket's pocket at 150 mph... , from the remaining 8 pieces the motherboard survived.., so bought another one with a not working one and put it in there.

The same no service and no sim card detection problem appeared on ios6.1 and for me the easiest solution was to go to:

Phone( where favourites, recents, contatcs,keypad, and voicemail are), and select the voicemail then it ll realise something is not okay, and ask for sim card unclocking :)
