iPhones 4S/No Service after battery replaced

restore ur phone with itunes the problem will solved 99.9999999999999%

have you tried set correct date and time, then turn on airplane mode in settings then go to GENERAL THEN SCROLL TO RESET AND RESET NETWORK SETTINGS, WAIT FOR PHONE TO DO ITS RESET, THEN GO TO SETTINGS AND TURN AIRPLANE MODE ON AND THEN OFF AGAIN and watchfor search to find network. This has worked for me before. I would double check aenna grounding has been put back correctly under top screw of battery terminal.

good luck bob

Absolutely brilliant. Just changed the battery and couldn't see how I would have damaged any part of the phone when all it needed was the date/time /year changing. Thank you for your spot advice Simran.

Cheers

The problem is that you don't clean the pressure contact which creates wireless interference. You can see the step 5 on the iPhone 4S battery replacement page

When you take out the battery their is a little clip that goes under the top screw of the battery ribbon. It's some antenna ground. And we'll your in their check and clean the antenna connector.

Maybe try this,

First, before you plug it into itunes or do anything go into your itunes account, go to the Preferences in ITUNES (it is located under the top lefthand corner) of the page. Go into your backup history, you will see a listing of every the date & time of the back up & restore attempts. DELETE all of them, rest your sync history.

Clearing out all of the previous back ups might help you, it might allow you to back up and restore the phone from itunes instead of a back up of the phones settings. Then try the clock and date change, turn off/on and see where your at.

Also, are you positive your battery is the correct battery for that phone?

Also charge the phone up to 100% before doing anything.

I would almost say that you have something somewhere either unplugged but it looks like it is plugged up. Disconnect all the connectors and make sure they are plugged in fully, one might have been bumped just a little lose. Check the OTHER END of the antenna

Check the Antenna connection near the battery plug

After replacing the battery, forgot to check the antenna connection, after checking the cable that is loose, and after i plug it back, everyhting works fine

Error (1) is baseband, only thing you can try is reflow the motherboard. (In the oven for 2-3 mins at 180 degrees C). Good luck!

AWESOME - what great info Simon.

Switched time from manual to auto detect and turned off and on again and "searching had gone"

my symptoms were "searching" but 3G and calls were available.

No service or searching solution for when you replaced or reconnect the battery!

Reason is automatically set default time and date so screen is showing like no service or searching.

That's not an issue we have lot of ways just follow this any one method

1- Settings privacy location ON

2- connect to iTunes for two minutes

3- connect to wifi

No need to restore or format the phones.

Hope your problem will get solved more details contact me on what's app

The time and date are set to a previous year, it just confuses the phone, once you correct the time and date it works perfectly fine.

None of these worked for me. I reopened the phone and ensured the battery and antenna were properly placed, the cover degreased, the shield properly placed, etc. I had fixed the date/time, reset the network settings, restored iPhone from iTunes, left it connected to iTunes, tried toggling via WiFi and airplane mode. NO DICE.

HERE IS WHAT WORKED:

I chatted online with my carrier (AT&T). They had me read a couple of settings from my phone and sent a reset signal. BAM! Service.

If all else fails, but before fooling with your mother/logic board, contact your carrier.

My phone was stuck in "searching" after replacing my iPhone 4s battery so I attempted to restore it on itunes but now my phone is stuck in recovery mode and won't restore! Does anyone have any idea why this is? It seems to be a hardware issue seeing as it won't restore. Any/all advice would be much appreciated

i have the same problem its in emergency mode and when i type my password in it stays on the pasword screen and then goes black if you have any more info that would be great.

I have restored my iPhone 4S with DFU mode and it solved my problem.

I had the same issue with it showing Searching. The funny thing was that I could call and receive texts. Had to change my phone Time manually in General settings as suggested and leave the screen. Later I changed it back to Auto Set.

the date and time trick works v fine

Just wanted to say THANK YOU! I replaced my battery, got "searching," tried reassembling, cleaning, etc. and panicked! Reset the time and date and then reset the settings. When it restarted, all was well again. You guys rock.

How do you reset the date/time?

Mine is OK and the date time is in automatically-- it's also correct. Thanks.

Hi guys

Looking at this lengthy forum I've too had this problem after replacing with a new battery for my 4s!

I've tried everything even linking it to iTunes but no joy. I've been almost 5 days without calling signal only wifi.

I've been told by my network carrier that a faulty sim could be to be blamed! I'm going to try this otherwise IT will be a complete reset back to when I bought it again.

I think Apple must do something which must link up when things are changed etc. As now my silent switch is not working..... Spooky!!

worked for me thanks a heap!!!

I have tried the time reset option but then my phone just shuts back down. The battery is saying 100% charge but when I unplug it, it shuts back off to the apple screen.

Please help?

I have the same problem as Anthony. Wi Fi and everyting else but Carrier fine. Date toggled and now correct. With No Service showing, turn Auto off in settings for carrier selection and manually select a carrier. Indicator changes to Searching and a gray spinning beach ball appears to the right of the carrier selected. Indicator remains Searching until a Blue check mark appears beside the carrier selected. Simultaneous with the check mark, No Service reappears along with an error message that the selected cellular network is no longer available.

I get the same kind of error when I try using an old SIM card from another company that was replaced with a new smaller SIM when I upgraded my phone. In this case, I know that the SIM is turned off. So that is a clue about where the trouble lays. Its like the phone company itself is blocking the SIM. But with the ATT SIM that is giving me the No Service problem, I have spent hours online with ATT checking to make sure that the SIM is good by them.

I hope a fe more clues may help unravel this.

I have had a complete nightmare with this. Initially just the "searching" problem. So I tried updating the time countless times. Tried the flight mode thing on and off. Tried resetting the network. All multiple times. Nothing worked. Then went to iTunes tried to do an update but it wouldn't work due to some error. And my only option then was to restore to factory settings which also won't work. I can't believe that just changing the battery myself has led to this. Really frustrating. And I'm now left with all my data lost and having to buy a new phone.
