    My Google Nexus 5 Experienced random shutdowns. (I found nexus 5 shutdown in the morning for no apparent reason. Battery was at 97% when i restarted)

    Now, While i was copying my development game APK. I was copying the apk. Everything was perfect. While copying from windows 7, the opened the dialer app (and went to type *#*#4636#*#* to see Wifi state i was connected to)

    While i was typing, my device Crashed. Black screen totally. I pressed the power button and it showed "Google" but is stuck on it for hours. It is not going any further, It shows "Google". When i press the power button again, the device stops and again shows "Google". So i pressed the Power button for a fairly long time and now the device is shutdown. (Totally shutdown). I tried restarting but to no avail.

    Please help start my Nexus 5. It's running Android 4.4.2/

    Welcome to the forums.
    I would suggest trying to restart in recovery and do a reset.

    You may have to reflash the stock images in order to get your phone back up and running

    Master Reset doesn't work either. I connected the Phone but it doesn't get detected as storage. I suspect somethings wrong with the internal storage.

    Have you tried a factory reset? Hold down all three buttons and then go into the recovery menu and do a factory reset

    Are you rooted? If so, what custom recovery do you have?

    So i pressed the Power button for a fairly long time and now the device is shutdown. (Totally shutdown). I tried restarting but to no avail.

    Based on these comments, I guess your device isn't completely shutdown - are you getting this message about "can't mount cache" in recovery? How are you getting to this?
    Try what bjrosen suggested - (note that it will wipe out your phone).

    I haven't yet rooted my Nexus 5. (I don't want to void the warranty)) I was planning root afterwards.

    I get E: failed mount/cache etc... when i try to clear my cache partition in Recovery Mode. And now its totally shutdown (need to press the Power key fairly long)

    I am not sure if i should do a factory reset. (I am still scared about losing all my data)

    Sounds like if you don't do a factory reset, you not only have lost all your data, but the phone as well. If you were to call Google for a replacement, the first thing they would have you do is a factory reset. In doing a reset, all you loose is data related to apps such as games. Your "real" data, contacts/calendar/email are all in gmail (even your photos are all on Google+, assuming you had that set up to auto backup your pictures). After the reset, when you sign back into your Google account, all that stuff will re-sync.

    As a side note, in your original post, you said this happened right after you tried to copy a game you're developing onto your phone. I have not yet been certified as a genius, but if I were you, I would be highly suspect of the code in that game as the cause to your phone problems.

    Exact same thing happened to me. My phone rebooted and got stuck at the Google screen. It would not do past that at all. Booting into recovery mode didn't work either. I bought mine from the play store and the tech tried to troubleshoot over the phone for about an hour. Unfortunately they couldn't fix it. Got my replacement two days later (yea FAST). Hopefully you will be able to get one to.

    I had set up AutoBackup and Sync. I am going to reset my phone and see if it works.

    The game couldn't be the problem since i have tested the game several times on my PC and i had not yet installed it on my nexus 5. I was just copying the game onto my phone storage while it shutdown.

    Help.. Its stuck at
    Code:
    --Wiping data...
    Formatting /data...
    It is stuck on it for more than half an hour. (Formatting 2 GB shouldn't take that time)
    Well, how do i safely stop it. Will holding Power Off + Vol Up + Vol Down shut it down or will it damage the phone even further.

    If it can't complete a format then you're device is usually hosed. There isn't a safe way to stop it. You can try just holding the power button to turn it off and try again but don't hold out much hope - don't think it will work. Call Google and tell them what happened and a factory reset couldn't be completed. They'll send you a new one.

    You may have had the misfortune of receiving a device with bad flash memory. It is rare, but it can happen. Should be easy to get it replaced. If you are within 15 days of purchase, call Google. Else, you will need to work with LG

    I had a similar thing happen just now. I just left my phone and went to grab lunch and now it won't do anything. It had a full battery charge but even when I plug it into a charger it doesn't respond. I've tried doing to do the vol up/down, power button and still no response. Is there anything else I can try to get it working again? I really don't know what could have happened while I was gone. It's stock, I've never rooted it or anything.

    I've never heard of anyone having to contact LG. Unless something recently changed, as long as you got from Google, I'm pretty sure they take care of replacement devices directly for the 1 year warranty period (excluding broken screens and water damage).
