Thread: iPhone 4 CDMA - Won't power on after testing screens?

    Default iPhone 4 CDMA - Won't power on after testing screens?
    So I bought a iPhone 4 Verizon off Craigslist to test screens with. I was using the lcd/digitizer extension flex to help with testing screens with and I tested two screens and noticed it was very difficult to seat the lcd cable of the screens onto the extension flex. Anyhow, I started to test the 3rd screen and it finally went into the socket and it didn't work. I've never got a bad lcd from my distributor. Anyhow, I tested the 4th screen and it did the same thing. So i took the extension flex off and plugged in the original lcd/digitizer that was attatched to the phone and it still didn't work. It worked previously. I tried reseating every flex, new battery, and even restoring the iphone through itunes. It gives me a 1600 error, even with iREB.

    Any ideas on what went wrong :S?

    Still no luck. I'm getting 1602 error code now. Ive tried

    -Swapping logic board with another CDMA phone
    -Different cable, different computer, different host files, newest firmware 6.1.3

    I just have a hard time believe it went dead after testing screens. I'm going to try a program called Tiny Umbrella that someone recommended.

    edit: No luck with Tiny Umbrella. The screen flashed for a second, but other than that, same error. Now trying older firmware - 6.00
