no backlight, red exclamation and triangle in recovery mode, unable to charge

the backlight of my acer liquid e isn't working and the cell is also not charging. when i start it it shows acer logo and then battery low logo is shown. in recovery mode it shows me a red triangle and exclamation.

pls help

I know this is a stale thread, but this problem recently came up with my Liquid. I was able to get past the error by unplugging everything:

  • battery
  • SIM
  • microSD
And then reinstalling/restarting.

Good luck!
