Tools Needed to separate digitizer
i got the digitizer from ebay,
hot air gun
i used IR thermometer to measure
double sided tape
first i thought removing the digitizer completely, and i experimented in old broken evo 3D digitizer to find out at what temp the glue between the glass and the plastic digitizer starts to lose(85-90degree Celsius)
after i found out that removing the glass pieces from the digitizer layer would be much easier,
my buddy helped me with the heat gun.
keep it moving don't stop at a spot it will damage the lcd,maintain temp between 85celcius(185F)to90celcius(194F)
using the knife remove the glass piece, remove one piece at a time.don't dig deeper when glass pieces are completely removed start heating at the top slowly peal of plastic digitizer layer from the lcd,
During this process maintain the temp at 85deg cel because dna lcd did't have the side metal support if the temp is low or you hurried means the top layer of the lcd will rip off .
after that i checked the lcd it worked no bleed or blackink
I cleaned the old glue and applied the double sided tape. the seller did't gave me pre cut tape so i have cut 2mm for sides and copied the old glue patter at the top and bottem . align the lcd use tape on the backside don't forget to peal of the soft key light diffuser from old one and transfer it to new one
i attached couple of photo taken doing this in a rar file
a pair of hands will be helpful and luck from Jesus .
Be careful with the knife i cut my fingers twice and glass pieces will fly around so wear glasses.
