[Nexus 4 General] Codestor:
My N4 Story

I purchased Nexus 4 yesterday from ebay. It comes with a seller warranty, not a manufacturer's warranty.

It was working smoothly and perfectly fine. I came home, plugged it into charger and updated to 4.3. Everything was running cool for 2 hours.

Battery charged to about 40-50% from 1%.

And i was checking my mail on computer while it was charging.

When i looked back at the phone, it showed up a solid red light.

I unplugged the charger, red light went off. Plugged it again, it came back.

I thought let's unlock the phone by pressing power key. It didn't work.

So i was starting to worry now.

I started searching for "nexus 4 red light" and read about hundreds of pages and watched few videos.

At first, i was trying to get into android boot loader. And solutions like -

- Press Power button for 15 seconds, 30 seconds, 60 seconds.

- Power button plus Vol +

- Power button plus Vol -

- Power button plus vol + plus vol -

- Both volume buttons..

All these didn't seem to work.

And now i was like finding about unbricking the phone and stuff.

Downloaded software - LG NPST, Nexus Root ToolKit, etc.

It wouldn't work because the phone didn't power up at all, no response, no bootloader.

So i was real worried now.

And found out threads about removing battery screws and replugging the battery into the phone, etc.

I purchased T5 Torx and Philips Small Plus Sign screwdriver.

1) Opened the back cover screws using T5 Torx.

2) Removed the SIM slot.

3) Tried to remove the cover, but didn't work. Its real hard to remove it. I used credit card, nails, sharp objects and then finally a Thermocol Cutting Blade. I inserted the blade between cover and body and somehow it popped up. Starting from bottom corners to top corners. Removed the cover. I say again, "its very hard to remove the cover". You need proper tools to remove it.

Try and search for battery replacement kit, Somewhat like this - www dot youtube dot com/watch?v=5FlLncBp6jI

4) Opened the battery screws using Plus Sign Small screwdriver.

5) Removed the battery connection by popping it up and placed it back as said in this video -

6) Placed the cover back. And pressed power button, but didn't work.

Ok so I'm done with that and don't want to defibrillate the battery, so didn't do that.

Last try, charging for hours(1 hr, 2r, 5hr, etc) but never got it to work.

Called up the dealer and asked for replacement. He's sending a new product now and about to replace this one.

I am sharing this because maybe this can help someone in someway.

Please note that, once you get red light and cannot get into bootloader or can't power on.

Then don't waste your time trying to fix any software issue. Its a hardware issue and mostly related to battery problem.

The red light basically means battery is drained and needs to be charged.

This is my entire experience. Spent about 5 hours last night and 18 hours today.

I'll update this if i get anything to share. Just waiting for my new nexus 4.

So long story short - Solid red light and non responsive -> Replace it while there is time. Good luck.
