Actually there is no need to Enter an “Unlock Code” on the Apple iPhone, all the process is done through iTunes once you receive the confirmation of Unlock.
The most important part is if your iPhone has been jailbroken you MUST remove the jailbreak and all programs or files related to it from your iPhone, otherwise the official unlock wont work. Once your iPhone is clean from any Jailbreak Application please follow these steps :
1 – Install the last version of iTunes
2 – Make sure your iPhone is updated with the lastest version of Firmware
3 – Swiftch on your iPhone with an Not Accepted SIM Card
4 – Connect your iPhone to your computer using the USB Cable
5 – Launch iTunes & wait until iTunes detect your iPhone
6 – Now disconnect your iPhone and reconnect it after 10 seconds.
7 – Your iPhone is now Unlocked.
In Case your iPhone is not unlocked after the above procedure, just do a full “Restore” and you will see the message “Congratulation’s, your iPhone has been unlocked” once the restore has completed.
iPhone No Service After Factory Unlock fixes:
1. Insert unsupported Sim card, open Settings on iPhone, go to General -> Reset -> Reset Network Settings.
2. In Setting you will see AirPlane mode which you can also use to fix No Service on iPhone as well:
3. Insert Sim card and turn on/off Airplane mode several time while it will pick the signal.
4. Also while your iPhone is on, pop the Sim card out and turn off the power. Insert Sim card and turn iPhone On. Or, turn iPhone on, pop up the Sim card, turn iPhone on and insert Sim card. It worked for many.
5. Go to Settings – General – Cellular/Network and turn on Cellular Data, Enable 3G, Data Roaming and wait for the signal. If they already on – turn it off and wait for the signal.
I received the message “activated” or “unlocked” but when I plug it into iTunes, nothing happens: Try connecting to iTunes, perform a back up then restore.
Phone is Jailbroken and will not allow me to do a restore:
- You must put your iPhone into whats call “DFU mode”.
- Open iTunes and connect the iPhone to your PC/Mac.
- Press and hold the Home button and the Sleep/Wake button at the same time.
- After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode. Now you can do a restore on your iPhone.
iOS7 Update: Turn off Activation Lock for the unlock to be successful.
When you enable Find My iPhone on your iPhone, iPad, or iPod touch running iOS 7, the Apple ID and password you use for iCloud is securely stored on Apple’s activation servers and linked to your device. From that point on, your password will be required before anyone can turn off Find My iPhone on your device, erase your device, or reactivate and use your device.
Activation Lock is enabled automatically when you turn on Find My iPhone in iOS 7, or when you upgrade to iOS 7 from a previous version of iOS that has Find My iPhone already turned on.
Apple introduced Activation Lock feature when it released iOS7. The new option is tricky. From one hand, it is designed to protect unknown people from accessing your personal information. From the other hand, it gives headache to users who wish to unlock the device they purchased from other people.
The introduction of iOS 7 has changed the rules for iPhone users. Now if the Find My iPhone app is turned on, you are not able to update to new iOS version or unlock your handset without knowing the Apple ID and password of iPhone’s original owner.
This ID and passcode are stored on the Cupertino-based company’s servers. It is impossible to turn off Find My iPhone, reactivate the gadget and erase information on it without entering them. This happens because of the activation Lock feature presented in iOS version 7 and up. You turn it automatically when you enable Find My iPhone program or when you decide to install the latest firmware [updating from iOS 6 or earlier operating system].
If this is your device purchased from Apple or official networks you should simply turn off the application. Users who purchased their smartphone from someone on eBay or other platforms should make sure the previous owner erased all his information, settings and disabled Find My iPhone for you.
How to turn it off:
-Go to Settings.
-Sign in with your Apple ID, if necessary.
-Turn on Find My iPhone.
-Prior to unlocking a phone, make sure the previous owner of the unit has turned off findmyphone and erased all contents & settings.
