Blue screen crash after charge port replacement?

Ok so this has happened twice now with two different iPhone 5S. The first time sorted itself out after a restore of the phone through iTunes but this time I've tried almost everything I can think of but the phone just keeps crashing with a blue screen then re-booting. It happens every 5-10 minutes.

It happened after I replaced the charge port. I know this can happen when you put the wrong screws into the plate that hold the lcd/digitizer flex down but I haven't been near that plate. Didn't even remove the screws for the screen. All I did was a regular charge port replacement, all of the correct screws were put back in there correct places. The phone charges, syncs to iTunes and functions correctly in all other ways. I just can't seem to get my head around why this is happening. It seems to be a common problem but only when mixing up the screws for the screen. If this has happened to any of you guys please let me know. Any information will help.

Things I tried:

-Brand new battery replacement

-Tried another charge port

-Updated the iPhone

-Restored the iPhone

grab a needle and poke on the caps near the batteryconnector especially FL11, im having the exact same issue as you and the screen never came off, but the FL11 cap has come loose.

FL11 is not a cap, it is a filter (inductor)

So you changed the port and didn't remove screen?

That must have been tricky and must admit that's very bad practice..

You must be damaging something when your doing your repairs or else this issue wouldn't happen

Do you use anti static mat ?

Was battery disconnected before the repair?

I dont find it tricky at all and don't see how this is bad practice? I use an iHold to properly hold the screen up. Why take it out when I don't have to? Yes the battery was the first thing I disconnected and yes I use an anti static mat.


Well then your damaging something on the board when your repairing


Yeah well that's what I'm trying to figure out. If anyone has done this before that may know what I might have damaged. Everything on the board looks good and I'm usually very careful using soft plastic spudgers to remove the battery and other flex cables.

That means your iPhone 5s screen is damaged. You can ask your local repair store for help or try to replace it by yourself.
