Intermittent display, no touch screen, FIXED

My nexus 5 screen wasn't turning on. I could push on the back and it might turn on, or show a distorted display. It eventually booted and the touchscreen wouldn't work. It was a mess.

Oh, and before this the mic wouldn't work without pushing on the back. It was bad.

I followed this video for unseating the main display cable and battery. https://www.youtube.com/watch?v=OPuCmfhzgbg

I reconnected only the display cable, not the battery, and plugged it into the pc. I was hoping it would boot so I could remove its photos before sending it in for repairs.
It showed a no battery symbol, BUT the display was on, and properly working!

I reconnected the battery, and it booted normally. Touchscreen worked and all.

Now, there are no issues, no mic problem, no touchscreen problem, like new! Just thought, if anyone else is dealing with this same dilemma, they might find this post helpful.

Note: This is my second nexus 5, the last one had major battery issues and needed to be replaced. Don't know if I'd buy another LG (nexus) phone after this.

Intermittent service after unlocking by IMEI

Hello there, this is my first post here, I searched all the forum but could not find any solution to this.

I have a Optimus G E987. Unrooted, unflashed, with original rom, didn't do anything to the phone yet as I recently got it from a friend.

My friend was under a different carrier that I am. Since his contract had expired I was free to contact his carrier and get the unlock code to unlock my phone by IMEI. After succesfully unlocking the phone, I inserted my old sim card, it was a Standard Sim so I had to trim it to fit on the Micro Sim slot the Optimus G has.

Everything worked beautifully until I started having signal issues, both data and phone.
It does not happen everywhere, but it definetly happens at places I had perfect signal with my old device like my work place. To solve it, most times I can go to the network settings of the phone and choose the auto select option. This restores the service but I lose it again in a few minutes. Sometimes this does not fix a thing and I can not recover service at all.

I know its not a hardware issue as my friend had no signal problems whatsoever. Maybe I need to set up something in my phone to get it to work properly but I am completely clueless. I suspect it may be the sim card as well.

Any help will be greatly appreciated.
