Unhappy [HELP] Phone randomly blanks out.

Hello everyone.
I'm in need of some help here, as I live in Albania, and I bought my phone from ebay, and I am unable to RMA it, so I have to solve this issue by myself
So, a week ago, my Nexus 4 just blanked out, and couldn't be turned on. Whenever I plugged it in the charger(OEM charger or usb), it would show me the famous Red Light of Death. So basically, the LED would blink, but the phone wouln't turn on even if left to charge for the whole night. After browsing this forum for days, I found this solution, which technically fixed the red light of death problem:
http://forum.xda-developers.com/show....php?t=2128392
So, he suggested to remove the back case, and just unscrew the battery screws, and that's it. After trying it out, it worked. I was able to boot my phone, so I just left it without the screws. If I put the screws on, the phone would show me the red light of death after one or two hours and wouldn't boot. I also tried pushing the connectors with my finger, and the phone would blank, and show the red light of death. So there is something wrong there. Anyways, I removed the screws, and just started using it normally. However, now, another problem appeared. The phone randomly blanks out. I am unable to find out the cause. I see the battery log, and it jumps from 80% to 0%, and turns off. Then when I turn it on, it says 80% again. My first thoughts were that the battery might be reporting the charge wrong, so I left it to charge, and installed a battery monitor app, and set it up to log every 5seconds the battery. Here is part of the output while it is charging(I have attached the whole log, but this is the interesting part):

2013/12/06 21:48:26,240mA,82%,3.919V,26.3C

As you can see, it was charging at 82%, then it dropped to 56%, showing some strange values, and then it went up to 82% again and then went on charging. My thoughts would be that it was about to black out, but because it was running on AC power, it didn't shut down, just the battery became unrensponsive. I don't really know how this could be happening, just my thoughts. One more thing, it charged really fast up to 80%, i mean for like 10min it went to 80%, but now for the last 10%, it is going slowly, and it has stayed at 99% for like one or two hours, charging it says. Also, I am using the factory images. This happened after the 4.4 update, don't know if it's related. I flashed all possible factory images, and now I'm on 4.3 again while I'm testing it.
Please if you could help me it would be great, as I have no choice but to either throw it out(can't afford another phone) or to repair it myself.
Thanks in advance.

It could be a faulty battery. Or the circuitry that detects battery percentage could be messed up (unless that's part of the battery.) As for the random shutdown might be attributed to poor connection? Just a thought.

As far as I know, the phone has never been dropped or been in contact with water. Yesterday I removed the battery, and yes, I did ruin it. But there was no leakage at all, as far as I can see. Well, I tried powering it on, and playing with the battery circuit, which is at the top side of the battery, and the percentage shown on my phone was acting weirdly. It went from 65 to 2 in a touch with my finger and so on. I am suspecting it could be a bad battery, but I can't explain the fact that most of the times, it would just drop the network signal, and ask me for my PIN code every 10 minutes. How can the battery and network signal be connected to each-other?

I ordered a replacement battery today, it'll take some time to come though...

I did order a replacement as well. I don't know what to say about the battery. Mine looks like this as well. What worries me is the problems related to network connectivity

Just received the replacement battery. Looks like my old one was really inflated. It was bulkier. Let's see how it goes
