Replacing all parts to the new midframe

Mi Problema

I'd like to replace iPhone to new midframe & replace Frosty dispaly to the original one.

Mi Solución

I spent about 3 hrs to replace all hardware to new midframe, but I did it! But I have some problem with Proximity Sensor, it doesn't turn off display while talking

Mi Consejo

Be careful with screws and other small parts, don't lose it!
