Remove the battery compartment cover. There are 
four screws in this area that need to be removed. Two 
are immediately visible on either side of the serial 
number sticker. Remove them with a small Phillips 
head screwdriver and set them aside. There are also 
two hidden screws under the sticker (if there is no 
sticker, all four screws are visible). To remove the 
sticker, use an x-acto blade or razor to get under-
neath one of the corners and peel it up gently. Once 
you get it started, you can use tweezers or small 
pliers to peel it off. If you are careful, you can lift the 
sticker and still be able to re-apply it later. Remove 
the two screws and set them aside.   

 
 
 
 
 
 
 
 
 

Now it is time to remove the black ‘rubberized’ back 
plate. This looks like soft rubber but it is actually a 
hard piece of plastic. Start at the top using a small 
pry tool and pry up the left corner. Then, move to the 
top right corner and pry that up as well. Once the 
two top corners are free, you can move the pry tool 
to the middle and, like a lever, bury it deeply and 
pull gently forward, prying the back plate towards 
you. This is not an exact science and you may need 
to experiment and pry in a few different places. You 
may also pry at the sides and use your hands to keep 
the piece from locking itself back in its side groves. 
There is a tab in the middle/center of the plate that 
will offer some resistance so the plate may come free 
suddenly. The only thing you need to really be aware 
of is that, on some H900’s, there is a sticky piece of 
double-sided tape at the very bottom of the plate 
(just below the raised dot). So, if the plate seems to 
come free but appears stuck in this area, use your pry 
tool to ‘peel’ the plate off of the tape. Once the plate 
is off, we can move to the next step.
