Unhappy [Q] N4 Steady Red Light despite new Battery - Data recoverable?

Heyas guys,

I had my N4 on charge overnight, woke up to the alarm i set but as soon as i touched my phone it turned off and wouldn't turn on again.

on charge it showed a steady red LED. i realised that the charging cable had its D+ and V+ (Green and Red wires) broken so i assumed the battery had just reversed its flow of current and drained.

I tried all the button combos to no avail, so i ordered a NEW battery and replaced it just then.

still no boot, steady red LED on charge.

Any Solutions? (i've searched)

and any way of getting the data off somehow?

thanks!
