How to Open the Back to an Upstage
- 1). Contact Sprint customer service at 1-888-211-4727 about your battery issues. Make sure your battery is fully charged and there is not a problem with the charger or outlet before attempting to dissemble your phone, as this will void your warranty. It also could be dangerous because if you don't do the job right, you might shatter the screens and produce hazardous shards.
- 2). Locate two small screws on either side of the Upstage and remove them.
- 3). Pry the phone apart using the narrow end of the screwdriver, starting at the bottom seam and working your way around. If you meet resistance or come close to cracking the LCD screen, stop and contact Customer Service for advice.
