How to fix your blank iPhone screen

Don’t panic! The blank screen on your iPhone 3G, 3GS, 4 iPhone 5s and 6 can be fixed, easily!
Fortunately, I worked out that you can fix this problem by resetting your phone. Here’s how:

Press and hold down the Sleep/Wake button and the Home button simultaneously for at least 10 seconds. The screen will clear out and then the Apple Logo will appear on the black background. When the logo appears it means that the reset is done.

Afterwards you’ll see your screen light up and you’ll be able to breath a sigh of relief!

What you will need is the original IPSW Image from Apple or 4.2.1 or  4.3.3
A Custom Restore Image 4.3.3 IPSW if you have lost your own, one is filed here with a prefix of NO_BB so it will preserve your existing baseband.
Get the latest Redsn0w – RedSn0w  —  Mac is 0.9.9b7.zip and Windows is 0.9.9b7.zip
1) Make sure iTunes is not running.
1) Launch redsn0w > Browse – select the original Apple Restore Image IPSW – iPhone2,1_4.2.1 or  iPhone2,1_4.3.3
2) Select your correct model according to the Serial Number – let redsn0w parse the image
3) Select only “Just enter pwned phone in DFU mode right now“
4) Follow the steps in redsn0w to get the iPhone 3GS into DFU mode which is going to send the screen to black
5) Launch  iTunes, hold the shift/option key whilst clicking on “Restore”, then navigate and choose the custom restore –  either your own or the downloaded one that starts with NO_BB (which preserves the existing baseband).
6) Say a prayer
7) You should now boot up to a familiar screen, happy days!
8 ) Restore data from iTune backup.

To Re-Jailbreak

1) Launch redsn0w this time selecting the original Apple restore image –   iPhone2,1_4.2.1_8C148a_Restore.ipsw, or iPhone2,1_4.3.3_8J2_Restore.ipsw  and  only select the option to “Install Cydia”.
2) It will need to enter DFU mode again, follow the steps and the screen goes black, and then the jailbreak process begins, unix flying bash code and running pineapples.
3) iPhone reboots – install ultrasn0w from Cydia to re- jailbreak the device.

 

 

No SIM card error

Potential solutions:

• Try toggling Airplane mode on and off again.
• Restart your iPhone by turning it off and on again.
• If you recently inserted the SIM card and started getting the error then there’s a chance it’s damaged or dirty. Try popping it out and taking a look. You can use a pencil eraser to clean the gold contacts and then blow away the debris before putting it back in your iPhone.
• Make sure that your software is fully up to date via Settings > General > About.
• Try the SIM card in another device if you have a compatible device, or try a different SIM card in your iPhone 6.
• If the problem persists then contact your carrier or Apple.

Step 1: Prepare your iPhone for restoration
Connect your iPhone to your computer via USB and click the gray Back Up Now button when viewing the Summary tab for your given device in iTunes. Alternatively, follow our guide on how to use iCloud to back up the device you Apple’s remote servers. Although backing up your device is not necessary, doing so will store your photos, apps, contacts, settings, and other data so you can automatically restore other iOS devices from the backup down the line.
Step 1: Access the Reset menu
Tap the main Settings icon when viewing the homescreen, select the General option on the resulting menu and tap the Reset button at the bottom of the next page.
Step 2: Reset your iPhone  
Tap the blue Erase All Content and Settings option second from the top, followed by the red Erase iPhone option in the resulting pop-up window to confirm the decision.
Step 3: Ensure the phone was restored
Once the restoration process is complete — a process that may take up to several minutes — check to ensure the phone has been restored to the original factory settings. If done correctly, you’ll once again be presented with the iOS Setup Assistant upon startup, from which you can then restore your phone from backup or continue the process as if setting up a new phone entirely.

Step 1: Prepare your iPhone for restoration
Click the iTunes menu located on the left side of the main iTunes toolbar, select Check for Updates from the resulting drop-down menu and ensure you have the latest version of iTunes. If not, download and install the latest version thereof. Afterward, connect your iPhone to your computer via USB and click the gray Back Up Now button when viewing the Summary tab for your given device in iTunes. Alternatively, follow our guide on how to use iCloud to back up the device you Apple’s remote servers. Although backing up your device is not necessary, doing so will store your photos, apps, contacts, settings, and other data so you can automatically restore other iOS devices from the backup down the line.
Step 2: Restore your iPhone
Once the backup is complete, click the gray Restore iPhone button when viewing the Summary tab for your given device in iTunes. Click the Restore button in the resulting pop-up window to confirm your decision, and if prompted, click the Agree button to agree to the software license agreement and begin downloading the necessary iOS software file before restoring.
Step 3: Ensure the phone was restored
 Once the restoration process is complete — a process that may take up to several minutes — check to ensure the phone has been restored to the original factory settings. If done correctly, you’ll once again be presented with the iOS Setup Assistant upon startup, from which you can then restore your phone from backup or continue the process as if setting up a new phone entirely. It’s like it just came off the assembly line at Foxconn all over again.

 

 

Problem: Home button not working

If pressing the home button on your iPhone doesn’t always get a response, then the device may have a problem, even if the issue is intermittent.
Solution:

• Apple is apparently aware of a manufacturing issue with the Home button on some iPhone models. Make an appointment with the Genius Bar at your local Apple Store to discuss the issue.
