Hi all, I'm new to the forum.

I replaced the battery in my iPhone 5 this week. Afterwards it wouldn't turn on. The screen stays completely blank. I've tried holding home and power buttons together. I've also tried connecting it up to iTunes. Funnily enough the phone is recognised and I can see the battery charging status in iTunes but the storage bar is all yellow instead of split up depending on content. My computer also lets me access the hard disc so can still view photos.

Any idea what may be wrong? I've tried the original battery back in the phone but no change. I may have to just sell the phone for spares now, but not sure how I would wipe the hard-disc if phone won't turn on! iTunes fails when I try to sync it.

Any help would be great. Been a very expensive week
