Question : iPhone 4S Stuck at boot showing NAND

2012-07-16 00:11:02

A friend of mine dropped his iPhone 4S in his pool. After drying it out with rice for a while, it got stuck in a boot/reboot cycle. That was a month or two ago. Today, he plugged it in and turned it on, and it got stuck at the boot logo and showed some scrolling text.

It's toast. If it wasn't jailbroken, take it to the Apple Store and get it replaced. An out of warranty replacement for a 4S is $199.


If it was jailbroken, throw it in the trash and buy a new one.

No,Dont throw it away. Try all the basic troubleshotting tips.. Does any of the buttons still work? What happens you you plugg it up , does itunes detect it? Also try pressing the home and power butto together to do a hard reset and see if that happens. all that is happeneing is it is doing a verbose boot. Where it shos all the command lines.
