iPhone 4S stuck on Apple Logo, rapid repeating of logo

[CRip4s]

My phone just stopped working a few days ago, and would still boot up past the Apple logo. It randomly would do the connect to itunes thing as well.

Now my iPhone just comes up flashes the Apple Logo and keeps repeating.

I have tried many different things to try to restore, or fix my phone but nothing has worked yet.

It was last running on 5.1.1 & was jailbroke on absinthe 2.0 untethered.

If anyone has an idea or can help me I'd appreciate it.

Do DFU mode (screen should be black in DFU)
then Restore as New

I have done that as well, it goes into DFU mode.
I have selected my own ISPW that I downloaded, and it goes and connects to apple and trys to send the update to the phone and my iPhone turns on then just keeps flashing the White Apple Logo. Then eventually it will have an error of 1600, or 1602

need to point it at Apple server most likely it's on Cydia's now.. I copied this because it's a good description http://www.jailbreakmatrix.com/howt...0-when-loading-5-0-1-5-1-5-1-1-and-even-ios-6

The main reason for this when restoring to Apple’s current firmware 5.1.1 is that you have a host entry redirecting gs.apple.com to the cydia verification server instead. So when iTunes tries to verify the data is sent to Cydia rather to Apple. Which is exactly what you want to do when downgrading your iOS firmware to something previous then the current firmware. But since we just want to restore to the current 5.1.1 firmware we need to actually communicate with Apple and not cydia.

I’ve been doing this a long time, and everytime I see the error, I just double check my host file located under

windows c:\windows\system32\drivers\etc\hosts

os x /etc/hosts

and if i see anything with gs.apple.com I just comment it out using the # or erase it totally, this has always fixed my issue, however not yesterday.

So after pondering around a little bit more, I discovered what the problem was.

I have TInyUmbrella installed, i fired it and unchecked the “Set hosts to Cydia on Exit” and then exited

I then fired up iTunes again, and viola, no more 1600 errors !

Really weird if you ask me, even though the hosts file doent contain an entry for gs.apple.com to redirect, Tiny Umbrella is still redirecting in another way, so make sure you check both not just o

It is still not working.

It is still not working.

So what did you do and not do ledt my psychic hat a home.

I have put the phone into DFU a few times and tried restoring by selecting my own ISPW, as well as downloading one through iTunes. Just get errors.

I can't get the phone into recovery mode where it shows the cable and the iTunes symbol.

I have even tried the hosts file thing, I went in and deleted anything that referred to the gs.apple.com.

Went to the Verizon store and my phone was under warranty and they sent me a new one!
