I have 4 iphone 5c's and found an old iPhone 4 (not s) that I don't use anymore and wanted to give it to my son to use as a fancy ipod but I have forgotten the passcode for it and haven't synced with my new macbook pro. Is there an application or way to force a factory reset bypassing the passcode? All his sisters and brothers have iphones and he feels left out The device in question has been used on my apple account in the past, I just don't know how to get around the passcode thing...

I do not have my cable at home, and I am having the same problem. I am without a phone for at least the weekend.
There is no way to factory reset through the device? Old blackberry devices had this.
Also all I did was upgrade an app through blackberry's app store. How can that cause such a critical issue?
Is RIM working on that? I see this problem is very wide spread, makes you wonder what kind of QA work is being done on the dvices.

My N97 is updated to the latest. I go to MENU-->>APPLICATIONS-->>SW UPDATE, it scans for updates and shows 'ALL APPLICATIONS ARE UPTODATE'. Now then, if i reset the device with a *#7370#, will it delete these updates as well? Not that i intend to reset my device, just curious world laughs with you. Cry, and the world laughs louder.

I installed the lollipop update and now get constant "unfortunately, the system UI has failed. This happens for a variety of reasons and has rendered my phone pretty much useless for anything other than making a phone call. Most of the other accessories, apps and program either only have limited functionality or are unstable and shut down.
So, What is the best method/process to reset my phone to pre-5.0 and/or to reinstall 5.0

I have purchased a 2nd hand Samsung galaxy s5 online. it wont et me access the phone as it is locked due to an abnormal factory reset and is requesting a Samsung account id and log in - clearly I don't have one and it appears it needs to be the previous owners. Is there a way around this in order to access the phone?

I recently have been having some weird problems with my HTC One M7. My battery has been draining a heck of a lot faster than it used to. It has also been lagging quite a bit. Sometimes extremely.
For example. One day it drained 40% in one hour. As I am typing this, it has drained 6% in like 3 mins. That's insane.
For an example of lag, it has been registering short presses as long ones, or taking a long time to pop up the lock screen, or open the app drawer. Some times a few seconds.
I recently installed the newest sense update, and installed tasker from aptoide, but then deleted it.
When I tried to factory reset it, it does nothing. Same for removing device admins. ( I was trying to uninstall ac display).

I am trying to reset my brother's iPhone that he no longer uses. He has upgraded to the iPhone 4. I do not know his passcode. I am unable to reach him to retrieve the passcode. How would I go about resetting the phone? When I try to reset it by holding the Sleep/Wake and Home buttons, the phone's screen just flashes at me. It does that as well when I try to shut it off.
Info:
iPhone 3GS

Since the last windows update from this week windows cant detect my nexus 5. I tried everything. It keeps showing up like "Unknown USB Device (Device Descriptor Request Failed)" And i doesn't show up immediately when i plug in the phone. It takes like 10 seconds, then it shows that with a yellow triangle.
