i just thinked like 10minutes about your question and it isn't easy one for sure

have you tried other charger and cable ?

but i have an idea

for that you need an multimeter (voltage check thingy try to lend one becouse these $15 are a piece of sh*t !)

try to cherge your battery then messure the voltage

<3.2v -> Dead

3.4v-4.0v -> Charged

4.2v -> fully charged

>4.2v -> overcharged ! disconnect (othervise it may blow the Sh*t out of it (inc. your phone...just lookup youtube if you curious...)

so if it's fully charged it should be like 4.ish volts and if it gets within few minuted to 3.2 volts then that's bad baterry

i have no idea what other thing can cause this if a line is broken it won't start or charge the battery

so it could be that the charging circuit is crap

also check the pcb for damages junk or whatever dosen't look healthy

just let me know if you get smth!

if shaking your phone helped than i have no freakin idea

i don't think it resets becouse of missing screws ...just buy some...

bad date and time is becouse the little battery (or cap) inside could be dead

shake it like a boss if you want :)
