LG D802 knock code - GSM-Forum

Destinycz · 05-15-2014, 13:20

Hello,

I need an advice regarding LG G2 D802. After the exchange of LCD module everything works fine. Only problem is unlocking(Knock code) the device by tapping on the display. Locking up the device with double tap works just fine, but the device won't unlock. Besides this, the LCD module works just fine. Hard reset and updating the SW through LG suite won't help.

Still no solution? Is anyone looking for some help or its dead topic? I would appreciate every help.

Same problem here. Touch works great. Knock on works 1 out of 15 times, knock off works every time. Weren't a problem before screen replacement.

Hi

You guys forgot the proximity light guide from broken screen
The black gum part

Take care of the flexes and all the stickers to put back from old one.
So many iphone screen changers break the bottom lcd flex trying to change it.

Have you took all adhesives and insulation tapes from old one ?

Just make sure the rubber is pressing against the glass, put the proximity sensor back in and place a small bit of card over it, secure with the black upper plastic circuit board shield, all done
