K850i disassembly
If you require a new screen, phone cover and screwdrivers, they can be purchased here: http://www.formymobile.co.uk/proddetail.php?prod=k850lcd
Tools required: Torx 6 screwdriver, Torx 5 screwdriver
* Using the torx 5 screwdriver remove the two screws which hold the battery cover in place, located where the screwdriver is pointing in the picture below























With the battery cover now removed you can remove the back cover. Run a credit card all the way round the edge of the housing to release the clips which hold it in place












Your phone should now be in 3parts, like below. Remove the two torx 6 screws at the top of the phone, circled in red. You can now release the front cover. It's held on by a number of clips that need to be released. There is one near the top of the phone that needs a bit of force.





With the front cover removed your phone will look as below. Lift the keypad part from left to right to access the ribbon from the LCD






The ribbon from the LCD, pointed to in the picture below, is attached like a plug and socket. Simply lift it up to detach it













Lift away the old LCD. It will be held in place quite tightly by clips around the edge of the housing. Just give it some gentle force and it's release
