i got a new 6gtpy and i charged it to 100% and then discharged it till the laptop turned off and the charged it again then...

in the connector itself there is a switch that disconnects the speakers it might be broken/destroyed not that easy to fix unless you destry the connector better to get a new one if possible.

depends on phone manufacturer and model. parts of your data is stored in a root partition, and without being rooted you cant access it and rooting a phone might clear the memory and thus nothing will be accessible one way would be to desolder the "flash" and read it, but if this is encrypted you will be out of luck there might be a specific software/app that can read rooted info to make a backup of it ie messenger backup or some other software this depends if you want to recover all or just some of it. this sound easier than it is in reality there are lots of reason that data is stored in a root partition like digital certificates or encryption keys. i hope this can get some ot it answered. regards sphinxios
