So i have a iphone 4s to fix and i have tried every low level fix i can think of.After installing a new lcd found the...

Take the phone apart completely clean the board with 90% alcohol remove the shields over the chip.Maybe use a tooth bush with sooofffftttt teeth over all the chips.But you may need a new screen,battery and or backlight ic and coil.

How did you break it?Are you sure you ordered the right screen because there are different screens for the verizon and the at&t versions.Last try a hard rest if that does not work you could have gotten a faulty display.Other than that it would be a board issue

If the phone has both gsm and cdma chip it should work global.You need to unlock your phone.A untethered jailbreak has been released.

The screen is very different more pixels to push.so i would think that it would be different on the inside.I have the same problem but it is just a generation jumped.I have a buddy with a oscilloscope and will be checking that asap.I could post a picture to see if they match with what you or someone else reports.
