infinite apple logo/frozen


Hi
I am a newbie to the i phone4 and had a buddy of mine jailbreak it last month. Today I clicked a link on Cydia I believe, and it asked me if I wanted to upgrade some of my apps. I clicked yes. Everything downloaded fine and than I was prompted to reboot which I did. Well I was never able to fully reboot and got stuck on the "white apple logo" screen. At times it will show the circle bar in front of the apple sign as if it's loading but nothing ever happens. After 5-10 minutes the screen goes black and than turns back on with the apple logo & repeats the same process.
I tried turning it off and on but had no luck. I held the power & home key down until it turned off again, waitied, than tried turning it back on with no preveil. Still doing the same thing....

Can someone please help me! Again I'm not real tech savy but I believe I had 4.0 or 4.1 OS with an I4 phone. And I don't want to lose any of my saved information or apps. I tried tiny umbrella to "kick out of recovery" but that didn't work either. Any information would be greatly appreciated!

in most cases PMIC is shorted. You must change pmic.

you have cleaned the phone and make some minutes in Ultrasonic?

i see this problem with a falling phone. There was a little bit of solder tin or tin balls laying on the PCB and make shortcut in a hided place.

or give it to a reflow oven. Maybe this is a solution if you haved changed the pmic before.

Hi.

Anyone knows how to fix the backlight in iPhone 4?

It was waterdamaged but it synch's with itunes, everything works but no backlight.

So i need to replace the coil but i don't know where it is..

Any help will be appreciated
