iPhone 4: How can I fix my disabled iPhone 4?

Sun, 26 Oct 2025 17:36:39 -0700

My brother's friend gave him an iPhone 4, and it's disabled. All we can do on it is slide the lock screen to call for an emergency. We've tried to connect it to iTunes and it's not working; it just says "error." At first, it said iTunes needs to be updated, so we updated it. Then it says "iTunes cannot connect to iPhone because it needs a passcode." It tells us to enter the passcode and try again, but the iPhone itself doesn't let us do that. I want to make the phone work for my brother.

Samsung Galaxy S5: Can't sign in to Samsung account after factory reset

Wed, 18 Mar 2026 05:47:08 -0700

I forgot my password and chose factory reset by turning my phone and holding volume up key, home button and power button together. It resulted in my phone being locked. But after reboot, it asks for Samsung account ID and password. While entering the ID and password, the processing fails and can't access my phone any more. I have reset my password several times, but still same result.

Someone can help me to resolve the issue.

iPhone 4: iPhone 4 Disabled but cant connect to iTunes to fix it

Wed, 16 Jul 2025 14:16:00 -0700

I just got an iPhone 4. I set it up with a passcode so no one would go through it. My friend tried to unlock it, and now it's disabled to the point where I have to connect it to iTunes to enable it. I didn't have a chance to connect it to my iTunes before he did that. When I try to connect it to iTunes, it says that I have to remove the passcode, but I obviously can't. How do I fix this?

Samsung Galaxy Tab 7.0: Doesn't turn on and says to download custom OS.

Fri, 19 Jul 2024 04:56:07 -0700

One day my Samsung Galaxy Tab 7.0 turned off, and I tried holding down the power and volume buttons. It said it needed to download a custom OS or press down on the volume button for restart. Every time I go to restart it just stays at the "Samsung" screen and when I go to download, it will just stay on the screen of the Android character. It says it's downloading, but it will just stay like that until it turns off. Please help.
