This guide is good but it should cover also the assemblying of the new digitizer. Distributors may sell digitizers with the ribbons not sticked to it and if the operator doesn't know they must be sticked, he will have problems during the assemblying.

Secondly, it should better cover the removal of the glass when it is cracked because the steps about the suction cup are quite ineffective. Please, cover the missing parts.

What about specifying the hot air temperature?

You forgot to mention to remove the SIM trays.

Thanks for the good tip.

The 2.5mm flathead doesn't fit the standoff screw. I used a 2mm flathead, but I had to be very carefully because it may be easy to slip.
