Hello everyone.

Have a problem with my Pi.
Everything was working just fine, i was having fun with xbmc, fm transmitter and other stuff. But one day, i turned my Pi on, and there was no image on screen. Tried to reboot - no result. I have decided to reflash my sd card, but same thing - no image, and i decided not to touch my Pi for some time.
About a week ago i saw a NOOBS image(1.2.1) and a new Wheezy(05-25). So i tried to revive my Pi.
Here is the photos from my screen:

NOOBS:

Just this, nothing more.

Wheezy:

"Successfully" boots until this. Interesting fact - there is no USB hub connected (or other usb devices).

Tried NOOBS and Wheezy with other SD card - same result, so SD card is OK.
Unfortunately, there is no other Pi to test SD cards.

Additionally I have tested power on board:
TP1-TP2 - 4.85v
TP2-F3 - 4.87 (difference between sides of F3 like 0.04v)
So everything must be ok.
Help me if you can. I don't know how to get it work.

Have you had a go at burning the SD card from a raw image and dd / Win32DiskImager? Is that what you meant when you said Wheezy(05-25)?
Do you have any other SD cards that you can try? It might be a bad sector on the SD card or something? Worth it to test it just to eliminate that as a possible cause. 2GB or more is fine.

You are running in "safe" or "recovery" mode. This (usually) occurs if you connect pins 5&6 on P1 together, or if Pin 5 is pulled low for any reason. Do you have anything connected to the GPIO pins when you boot up?

If it is a model B then it does have a USB hub connected. The LAN chip contains a 2-port USB hub as well as the network interface.

You should get a "#" prompt if you press Enter, but you can't do much from there. It is safe to switch off your Pi at that point.

There is a setting to prevent the recovery mode from starting, but it shouldn't really be needed.

Thanks for fast reply!

to Davespice:
Yes, i wrote image with Win32diskimager.
Yes,

Tried NOOBS and Wheezy with other SD card - same result

Both cards 16Gb.
By 05-25 i meant 2013-05-25 version of Wheezy.

to rpdom:
No, i don't have anything connected to GPIO.
How can i get back to "normal" mode?
And why NOOBS shows only "rainbow screen"?

You can get back to "normal" mode by putting in the config.txt file.

I don't know why NOOBS isn't getting past the "rainbow" screen

to rpdom:

Thank you very much!
Added the line, and Pi successfully booted!

So it looks like you've got a short or something on that GPIO for it to read low ...

Interesting that doing that makes NOOBs fail to load, it shouldn't try to load an emergency kernel...

Will check with Dom...

I found a fix!!! , what you have to do is type in 'fsck /' and then when it prompts you to say yes just hit 'y' then enter! Then after its finished hit 'ctrl-D' on the keyboard to restart then BANG your Pi is restored!
