iPhone 3GS Black Screen (Of death???)

[kieranfb]

I was listening to music in the car, and my iPhone 3GS just turned off. It went onto the black screen, and didn't turn on (It had about 80% battery). When I plugged it in when I got home, there was no response from it, same when in iTunes in 2 computers 1 after the other.

I have had it fully submerged in water, but the only thing that happened from that was the home button stopped working, so I know use assistive touch, meaning I can't put it in DFU as far as I know of. This was about a month ago and I haven't had any other effects from that so far.




Fast reply would be great, thanks.

What firmware are you running?

From here

What you need:

original Apple firmware
BetterZip on Mac or WinZip on Windows (or something similar, your choice)
How to do it:

1. Create a copy of the original apple firmware and change the file extension from .ipsw to .zip

2. Unpack the .zip file to view its content. Navigate to Firmware > all_flash



3. Inside you will get two folders ( all_flash.m68ap.production and all_flash.n82ap.production ) and both of them will contain various files. The ones you are interested in are:

LLB.m ** ap.RELEASE.img3
applelogo.xxx.img3
NOTE: asterisks stands for 68 or 82 – depending on the folder. “xxx” is a different number for each device.

4. Delete the LLB.m ** ap.RELEASE.img3 file in both folders and rename the applelogo.xxx.img3 file to LLB.m ** ap.RELEASE.img3

5. Save everything and rename the file back from .zip to .ipsw

6. Connect your iPhone or iPod Touch to your computer, open iTunes and click the “Restore” button while holding down the Alt key if you’re using Mac (Shift key if you’re on Windows).Now browsed for the modified .ipsw and restore your device with it.When iTunes is done restoring your device with the custom firmware, your iPhone/iTouch will load directly into the DFU mode and now you can restore.
