as i’ve posted before , my busted cell got ran over by a car . re fixed and soldered . aparently the undergrad diploma student did it with one eye closed . i found that one black wire is broken off but now dont know how or where it should be soldered to . any one ? help !
that was before re fixing . just after accident .
that was after refixing
this was just after 100m rolling . and suddenly stopped . see that button still at “ON” but no led indication .
now , at where i point is a tiny wire . at first i thought it was a plastic fastener . where should i solder it ?
