My LG phone won't turn on

[Android Question]

My LG optimus e405 won't turn on. When I was using it, it won't turn off (the screen) then I powered offed it and it won't turn on. When I long press the on button it will just vibrate and nothing happens next.

It sounds like your phone needs to be re-flashed with stock firmware. Googling "Unbrick LG Optimus E405" will return plenty of information.

Also, try this guide: Mods and Tweaks for LG Optimus L3 E405

May help you during the unbrick process.

I would suggest joining AndroidForums and finding users like you in your phone specific forum: LG Optimus L3 - Android Forums
