iPhone 4S Stuck at boot showing [NAND] ?

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.

[NAND]_FindFlashMediaAndKeepout :572 physical nand block offset 1

[NAND] start :343 this 0x81c0e900 PROVIDER=0x81c04c80 flashMedia=0x81c84c80

[NAND] WMR_Start : 145 Apple PPN NAND Driver , Read/Write

[NAND] WNR_Start : 170 FIL_Init [OK]

[NAND] WNR_Open : 367 VFL_Open [OK]

[NAND] WNR_Open : 410 FIL_Open [OK]

[NAND] _ppnvflGetStruct :3239 Checking borrowed blocks - count: 44 max_count: 44

[NAND] _fetch BorrowedList:789 number of borrowed blocks 37

This is what it looks like:

What does this mean? Is there any hope for the phone?

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.

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.

I'll have to ask my friend to try those... Although it's not looking good. If it doens't work it's not a big deal, he already ordered a replacement.

I dropped mine in the pool on Sunday. Completely submerged. I did rice for 24 hours and then placed it between 2 damp rid sachets. I checked it every day and it had the exact same screen as the picture above. Tonight I tried one more time. It stayed on that same screen for about 20 minutes and then miraculously booted up to its former glory.

Place your phone into recovery mode and then restore as new. You will lose everything, but at least it should work for you.

The iPhone is not user servicable. There are no legitimate sources for iPhone parts as Apple does not sell parts. There are a whole host of things that could have caused the problem. Most likely is damage to the system board.

I had this same issue. I started looking at what I replaced recently and I did a full front screen with the camera. I tried putting the old camera back on and it worked. Seemed to be a hardware failure.
