If that's the case, unlock your bootloader first and everything else can come later (Rooting, Flashing Kernel, Flashing ROMs, etc); as unlocking bootloader WILL wipe off every data on your phone. So the earlier you do it the less hassle later

owh.. looks like u'll have to go to either ur service provider(maxis, digi, etc) or just any phone store for the Sim Cutting

Cut my sim at Mydin USJ for RM5 only .But at IOI mall they charge RM10

But if im not mistaken sim cutting is like 50/50. If they screw it then u hv to applied a new simcard.

Red = Extremely low battery <15%
Orange = Usual charging
Green = >90% battery

Just let the battery to charge till you see the green led.Try booting your phone then.

Is your problem solved?

"Guys i can confirm that it is a battery drain issue
before doing anything to your lovely phone
just leave it for 10-15 min for charging on original charger

in between keep long pressing the power button to check whether the battery is charged to boot the phone o not

i have experience this the 2nd time now both times it revived by this charging method

Be patient dont tear your phones apart keep it as a last resort"

Give it a try?

my goodness, will it void the warranty?

May i know how long did u played the game till it shutdown? Is the phone hot? Demmn, i just thought of buying this phone. 

Remember that you may open the back cover without voiding the warranty.However you may void the warranty if you tamper with the battery.

Thank you! At first i was concerned about the back-glass cover will cracks however the risk could be minimized by getting a bumper for it.
And now come with the "Red light of death " issue @@

I'm not sure.Should be fixed permanently.
If you really want to give LG Malaysia SC a call ask whether you can disconnect the battery or not.
If they allow you so do so then go ahead & open your phone.But remember unlike some Samsung's cheapskate backcover, Nexus 4's backcover connected to some antenna parts.So be careful when you take it apart.
Glass will break.It's the physical character of glass.
No matter what fancy word manufacturers use to describe the glass it'll break if appropriate force applied to it.
Just use a decent bumper or cover to minimize the damage.

Yes, what i read was just remove the screw which gives too much pressure on the connection will do.

Is it possible reason the u got red light of death issue because of the heat ? (thermal expansion theory,热胀冷缩) which either the connecting bridge/screw expanded and gives more pressure on it ? Just my assumption.

Hopefully you can solve your problem real soon！
I've been thinking what if i leave my phone charging overnight. Afraid of overcharging it, do not know whether it will caused the problem or not . 

Oh? Thought you are fixing the problem now by taking out the screws ?

Okay! Do update with us after your fix!
Btw, what if you leave it charging? The device also left unresponsive?
