http://www.formymobile.co.uk/desiredisas... this is the only guide I can find on how to take your phone apart. You'll need to search ebay or similar for parts or a broken phone you can take the piece from. Also are you sure it's not a bad battery?
We have a chance to guarantee our right to repair electronic
equipment—like smartphones, computers, and even farm equipment. This is a once-in-a-generation
chance to protect local repair jobs—the corner mom-and-pop repair shops that
keep getting squeezed out by manufacturers.
Join the cause and tell your state representative to support Right to Repair. Tell them you believe repair should be fair, affordable, and accessible. Stand up for your right to repair!
