The new Motorola Droid Razr MAXX HD XT926 XT926M is supposed to be nano-coated internally to avoid damage due to light liquid, but it is not very often that the liquid coming into contact with your phone is merely a splash or drizzle. Such was the case with mine. My phone sat in a dual cup-holder adjacent to a (unbeknownst to me) leaking Styrofoam soda cup. By the time I arrived at my destination, the top of my phone was submerged in over an inch of soda.
The phone worked still, although the camera had stopped functioning. By the next day, the phone had run out of battery and would no longer power up. So began my quest to crack it open and see what I could see…
DISASSEMBLING THE XT926M:
– micro torx bits T3, T4 and/or T5 (my bits aren’t marked, but I believe these are the right classifications)
– micro screwdriver
– tough plastic prying tools
– [optional] ‘spudger’ too
(1) Removing the LCD Display – Touch Screen – Digitizer – Assembly
– we start by removing the only screws visible on the exterior of the phone – the two torx screws at the very bottom of the housing
– with the two screws removed, you can now carefully *SLIDE* (do not lift!) the LCD-portion of the display *BACK* (towards top of phone) from the lower half of the housing to disengage it, BUT BE AWARE IT WILL STILL BE ATTACHED BY 2 RIBBON CABLES. The LCD assembly frame has slight hook tabs which make it only possible to remove it in this slide-back manner.
– carefully unplug the two ribbon cables from the main housing by sliding them FLATLY towards the center of the phone to disengage from the main-board.
– DONE! You have removed your LCD assembly!
To remove the front-camera, remove the two torx screws, remove the metal housing, and carefully slide the camera’s ribbon-plug UP from the LCD-board plug.
– to reinstall, just reverse the above directions.
(2) REMOVING THE PHONE MAIN-BOARD (to get to the battery):
– remove all the visible torx screws (10 total) INCLUDING those on the camera assembly (2), the ear-phone plug assembly (2) and the remaining six on the main-board itself.
– carefully unplug the small power/volume switches ribbon cable from the right side of the main-board by sliding it towards the right side
– remove the battery power cable from the bottom-left of the main-board by first removing the transparent gold protective sticker, then sliding the ribbon connector down towards the bottom of the phone.
– lastly, and most difficult, carefully dislodge the main-board from the back shell BUT also pry out the speaker from the top-left when you get room OR YOU RISK BREAKING THE SMALL CONNECTOR WIRES! You will hear a small pop as the speaker un-snaps from the housing – then it is OK to continue prying the main-board from the shell.
– Note the small vibration motor is on the back of the board near the speaker.
(3) BATTERY REMOVAL AND FLASH REMOVAL
– The battery is merely glued to the back housing, but be careful in prying it out because it IS bendable, not rigid. Keep it from bending as much as you can.
– The flash module is removed by taking out the four miniscule torx bits that hold it in. Replace it in the same manner.
