Repairing Nokia 3310s, by swapping parts out with other broken Nokia 3310’s, is childs’ play. Almost anyone can do it.
However, without a Torx screwdriver, back in 2008, I used hacksaw to cut a groove in the top of each screw, and then used standard electronics/jewellery screwdrivers to unscrew the screws and take the device apart.
These days, I have Torx screwdrivers and no Nokia 3310s. Probably an improvement.
