HT201210 how to resolve firm ware coruppted iphone 4s

Why do you think your firmware is corrupted?

Iphone 3G shows Apple logo when starting and stops there.

Hi, I just got an Iphone 3G 16GB yesterday from a person who had it for 10 days and did not like it. Before giving it to me me he did a general reset using the optino in the settings menu. When he gave it to me the Iphone was still doing the reset and it took 2 hours and 40 minutes to end it. At the end of the reset the screen showed the Apple logo and does not go further. All of this was done with the Iphone plugged in a power outlet to avoid interrupting the operation.
I left it on for all the night just hoping it was a very long procedure but with no results (still the Apple logo and nothing else). This morning I tried to turn it off keeping the sleep/wake button pushed for some time but id did not even shut down. The only way I found to shut it down was to to push the Home button and the sleep/wake button together for a few seconds. When I tried to turn it on again pushing the sleep/wake button it showed the Apple logo again and nothing happened.
COuld someone help me?
Thanks in advance.

Just to report that the problem was solved with Apple Support. They asked me to start Itunes, connect the usb cable to the computer, push the home button while connecting the USB connector to the Iphone. This way Itunes recognized the Iphone in recovery mode and restored everything automatically.
Now the Iphone is working perfectly.
Hope this helps.

My iphone5 is in the same room with an ipad, 2 kindles and 2 iphone4S and it's the only one that does not have a wifi signal. pls help

why does my iphone5 not have the same wifi coverage as 2 other iphone4s in the same room?

Try restarting your iPhone by holding down the on/off and the home buttons at the same time until you see the Apple Logo. If you are still not able to connect try resetting your network settings. Go into your settings>general>reset then tap reset network settings. If both fail to fix your problem try restarting your router.

Cant restore 3g iphone just has apple logo and littke clockwise circle at bottom says 1603

like tittle says

i do that but it keeps getting stuck on the 'preparing to restore i phone' screen for a few mins before coming up with 'unknown error 1603'.
Just doublechecking. Have you worked through the 1603-specific instructions from the following document?

Have a look in the iTunes settings on the devices tab. When there is a lock next to the date your backup is protcted by a passwort. Than there is no way to get it exept you find the password.

Are you sure your friend didn't jailbreak it?
If so, save yourself a lot of time and trouble - throw it in the trash.

Same here. I tried to update my iPhone 5S and iPad 4 to 7.1 but iTunes wiped out them. This thing already happened for iOS 7.0.6 update. What happened to Apple? I am really curious whether Apple is aware of this problem.

My phone keeps freezing, the apple sign appears on the screen and then it freezes again and repeats itself.. has anyone had this before? if so, what is it? & it's also not letting me restore it from iTunes, it keeps coming up with error (9) or error (14).. help?

Hi there Holly N,
You may find the troubleshooting steps in the article below helpful.
Resolve specific iTunes update and restore errors
http://support.apple.com/kb/ts3694
Configure your security software
Related errors: 2, 4, 6, 9, 1000, 1611, 9006, 9807, or 9844. Sometimes as a result of this issue, a device might stop responding during the restore process.
Check your security software and settings, which can block ports and prevent connection to Apple servers during update and restore.
