renovate a k750i cellphone
My cellphone, model k750i Ercisson was inherited from my father so it was well used long before i got it.
After the years of being rubbed in my pocket, droped in walls, exposed for sms-writing-contest etc. it has lost it's brilliance.
The biggest problem is the dust, it has jostled itself between the joints of the chassi. The very sensitive lever has lost almost all it's capacity of navigation (interesting that we never see cellphones with such a lever on the latest phones...)
The dust has also jostled in between the display and the protecting glass meaning you can't see nothing when the sun shines on it (in all the situations you need the cellphone for checking sms, calendar etc...)

| Me and my father decided to open it up and clean it, make a big renovation! Tools: Torx screxdriver Small screwdriver (cross) Cleaning cloth Bottles with lubrication and compressed medium preassure air Motivated son and father We found a short guide on the internet, but if you need more help than this howto you can search for it at google <3 |  |
Step 1.
Release the chassi. Open the backside and remove the battery and SIM-card.
Remove the screws and then the front chassi.
Lift off the buttons.
Step 2.
Lift the white plate under the buttons. (You don't need to remove it)
Now you can use some of the compressed air to remove dust etc under this plate.
You can also lift the lever to remove the dust under it. We used some lubricate to make it clean, this made a lot to the renovation!
Step 3.
Clean the display from dust
Use the compressed air to make the chassi clean....
Step 4.
Put the parts together and feel the pleassure of a working, clean cellphone. It's really nice indeed.
