HTC Evo 4G LTE: The application (process com.android.vending)has stopped unexpectedly?

Wed, 26 Nov 2025 06:18:25 -0700

Google Play was accidentally uninstalled. I reinstalled it and now get the error message, "The application (process com.android.vending) has stopped unexpectedly. Please try again." Is there a way to save my phone? It's running Android version 4.1. I've only had the phone 4 days.

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?

iPhone 5: iPhone says "This accessory may not be supported"

Thu, 03 Oct 2024 21:00:33 -0700

When I connect my iPhone to the charging cable, it vibrates and says something like, "The accessory may not be certified." I've tried a lot of cables, including original Apple cables, but the results are the same. I've also tried to put my motherboard into another working case, but it does the same thing. Do you know which IC can be broken on my logic board? Thank you.

iPhone 5: Stuck in continuous apple logo loop, turns off when cable removed?

Wed, 26 Jun 2024 03:00:02 -0700

Hi there.

My iPhone 5 (model A1429) will not boot into iOS.

When the power cable is connected, the iPhone boots up initially and displays the apple logo for ~3.5 seconds. Then it goes to a blank screen for another ~2 seconds and the process repeats (indefinitely it seems - at least at this point).

When the power cable is removed, the screen instantly goes blank again. Nothing happens if I press the power button when the iPhone is not connected.

I can get the iPhone into recovery mode by holding the home button before I plug it in, and then it stays on the recovery screen, not coming on and off like the apple logo was earlier. Again, when I unplug the cable it goes back to a powerless blank screen.

The iPhone is detected on iTunes in recovery mode and I have attempted to restore it, using both my MacBook and a Windows PC. Each time, it results in an error at the point when the iPhone appears to restart. I see Error 2001 on the MacBook and Error 21 on the windows PC.

I've updated to the latest iTunes version, restarted the computer several times, and tried different USB ports.

I was also able to get the iPhone into DFU mode, where the screen was blank—but it was recognized in iTunes as being in recovery mode. Just as before, the device will not restore, and I get various error codes across my Mac and PC.

I have since opened the device up and confirmed that the battery is securely attached to the logic board.

It is also worth mentioning that my iPhone is no longer under warranty.

At this point. my assumption is that the battery itself is dead, and won't hold any charge, which is why the device shuts off immediately after removing the power cable. Does this seem reasonable and should I order a new battery? Any other suggestions?

Many thanks,

Bradley

iPhone 4: I can't hear my phone calls unless I put it on speaker.

Thu, 11 Dec 2025 10:07:46 -0700

I can't hear my phone calls unless I put my phone on speaker, but everyone can hear me fine—even if my iPhone is not placed on speaker. I've taken really good care of it and have only dropped it once, which was a few months ago. I just woke up the other morning after charging it, and it no longer works right. I've tried everything, including resetting it and placing half a Q-tip in the ear bud holder. I have an appointment at the Apple Store to have it checked out, but I live so far from the store that it would really be helpful for me to figure this out on my own. Does anyone know of a way to fix it? I would greatly appreciate it. =]

iPhone 5: I see a charging symbol, but the battery percentage is not increasing.

Thu, 02 Oct 2025 01:45:32 -0700

My iPhone 5 was working properly for more than 1.5 years. Now, I'm having a few problems with it. I will explain the problems one by one, after doing all the diagnosis I can on my end:

When I charge my iPhone, it shows the battery percentage indicator, but the battery percentage doesn't increase.
The charge indicator will stick on the number that's currently on the display.
After restarting the phone, I see the battery percentage increase—but this doesn't work every time.
Sometimes the phone charges properly, but I have to face this issue most of the time.
When I do a hard reset (home+power button), the battery percentage drops from around 25% to only 8%.
When I try to connect my phone to my PC, the phone restarts again and again.
Sometimes, when I use my phone while charging, the battery percentage will not increase.
When I charge my phone with the battery below 10%, the phone restarts again and again.
Sometimes, when the battery is totally dead and I try to charge it, the phone won't start, and it will only show the red indicator on the screen.
I've been facing this issue for the past week. My phone is currently on iOS 7.1.1.
When the phone gets to 100% charge, it does not show the full charge indicator on the battery.
I need to unplug and connect a few times to make the iPhone connect to iTunes, but iTunes works fine on the phone.
The phone has never been repaired before.
I've tried changing the charger and cables. I've also recalibrated the battery and performed a restore, but that didn't fix the problem.

Is this issue due to a bad battery, or is there some problem with the phone's logic board?

iPhone 5s: My phone keeps clicking on things that I'm not even clicking on?

Sat, 25 May 2024 10:54:08 -0700

Whenever I unlock my phone, it goes crazy. It starts having a spazz attack and clicks on random stuff by itself. For example, I will go to my messages to try to text someone and it will just start clicking on letters and buttons out of no wheres, causing me take 20 minutes just to send a simple message. I have no control over it and it is really annoying. This started happening after I went in the store to get my cracked screen replaced.
