[Q] Nexus 5 stuck at flying dots. Any pointers where to proceed. - Nexus 5 Q&A, Help & Troubleshooting

Hi Guys,
I was playing Clash of Clans on my Nexus 5 when my phone ran out of battery. I charged & switched on, from there my phone was stuck at flying dots. What I tried,
Hard Factory Reset
Wipe Cache Partition
Then again re-booted it, still again stuck at flying dots. Then used TWRP recovery, but still it stuck at flying dots.
After this little stint with TWRP, finally flashed Lollipop version5.1.1 (LMY48B), but again it stuck at flying dots.
But this time, I received ./cache partition error. I have used the steps mentioned in this link:

+ fastboot flash cache cache.img mentioned in here:

Though cache partition error got removed, but still was stuck at the same situation. Finally, roll-backed to KIT-KAT, this time it worked, but Camera, Gallery, Play Store was continuously crashing. When I opened the gallery it showed no SD card, then I downloaded few files + downloaded OTA update, they both got downloaded. So, I think internal memory is my fine, don't know the possible reason of this error. One more thing, my sim card was also not readable.
Few hours later, I again flashed my phone to Lollipop, then again got stuck at flying points.
PS : Apologies for making this post long, but just want to tell the methods I tried.

Resoved the issue using: http://forum.xda-developers.com/google-nexus-5/general/guide
Issue got Resolved. Nexus is Up again.:good:

What did you do to fix it, might help others

[Q] Internal Storage Corrupt

I installed TWRP to install a different kernel.
It installed and offered to wipe Dalvik Cache, which I thought would be a good idea. It then seemed to get stuck doing this, so eventually I turned off and rebooted.
It rebooted fine, but the internal memory seems to be unreadable and Google Play seems to constantly crash.
I thought the quickest way to start again was to oem lock and unlock again. It then seemed to get stuck booting up.
I got back into TWRP and did a data reset, which is now allowing me to boot again, but I still have no Internal Storage and Google Play still FC's.
I'm currently trying the Nexus 5 Multi Tool to reset back to original state (flash back stock ROM)
It's got 30 minutes to go, downloading the ROM... so I thought I would ask if anyone had any ideas for me?
Thanks.

Stuck in a loop, need help

Hi all
I’m a complete noob at this and it seems like I have got myself into a bit of a pickle. Sorry for the massive description but I thought it would make it easier to get a good answer.
My Phone:
Samsung Galaxy S4 GT 19505 LTE
PDA I9505XXUEMK8
CSC I9505BTUEMK5
MODEM I9505XXUEMK8
I successfully rooted my phone using Odin. In Odin I added the "CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5" file to the PDA field then rebooted the device. Then I added the "openrecovery-twrp-2.6.3.1-jfltexx" file to the PDA field, rebooted the device and the phone automatically opened in TWRP recovery. In recovery mode I wiped the cache, system and dalvik cache. I then went to install, browsed to the "I9505 Official_Google_Edition_4.3_by_Jamal2367_Finaly_v2.0" file on my SD card, rebooted the device and the Google logo came up on the screen for a few minutes and all was good. Got my new ROM, ran a root checker and all was good.
After some research I decided I wanted to use the Pacman ROM as it seemed to a lot more customisable. Using the same method I went to TWRP recovery wiped the cache, system, and dalvik cache. I then went to Install, browsed for the pacman ROM and the Gapps file on my SD card and everything installed ok, the phone restarted and the pacman logo came up everything was fine. Although I did notice on start up that I got this message.(and have had this error message ever since)
kernel is not seandriod enforcing
set warranty bit : kernel
After using the Pacman ROM for a day I noticed a lot of bugs like my apps would disappear, I couldn't use my banking apps and my phone was generally performing very badly. So I decided to remove the ROM and use CyanogenMod ROM under the recommendation of a friend. So again I pressed home+power+vol up to enter recovery mode but this time it didn’t enter the TWRP recovery it entered the stock recovery mode. This was slightly concerning but I proceeded to use the list menu and cleared the cache etc, browsed the SD card and went to the CyanogenMod 10.2 ROM I previously downloaded. It began to install but in red I got the error message stating that I didn’t have the right permission or signature. The phone rebooted back to the Pacman ROM. I tried the above three times and it still continued to boot back into Pacman ROM sometimes I struggled to even get back into recovery mode.
Soooooo I decided to try and go back to the Google Edition 4.3 ROM and play it safe, using the method from my first paragraph. But when it installed through TWRP I got an error message saying cant find MD5 file. The device rebooted and the Google edition logo came up on the screen but it seems to be locked in a loop. The Google logo wont go away and the phone vibrates once then three times quickly every 10 seconds.
I can still enter both TWRP recover and Download Mode. But I don’t want to mess around with it anymore without getting some advice. Any help would be much appreciated as I really need my phone working.
Thanks again
Aiden
Did you create a backup while on your first run with google edition? If so wipe cache, system, and dalvik and restore to your backup. Should put you back to where you began.

I know I should, but I didnt. Is it still fixable ?
*Update*
Couldnt help myself had to have a tinker around. Managed to get Cyanogenmod 10 working with Gapps. Gonna see how I get on with this. Although still would like to know I have been having all these problems.
Sometimes things just dont go as planned: p I have easily soft bricked my phone around 10 times and always able to fix it. You really should have made a stock backup before flashing anything. I recommend doing it now so you at least have a known working configuation backed up for future use. Trust me backups are your friends!

[Q] Stuck in boot animation after updating to L

So, I had the final L 5.0 flashed in my Nexus 5 when suddenly, after a poweroff, it wouldn't come back again, stuck in the flying dots boot animation. After many attemps and leaving it for the night, I tried re-flashing the L (LRX21O) back to it. No luck, still stuck in the flying dots (and yes, I did erase the cache and data partitions). I installed the 4.4.4 image and it booted; however I had some *very* weird problems, like the internal memory not being recognized (camera/gallery/appstore wouldn't open, got error about missing sd card, in the nexus 5). Then tried to update OTA from KitKat to Lollipop and got stuck in the same stage; those damn dots!! Can anyone help me "unbrick" my phone in Lollipop?
Ok, I reinstalled kitkat. While it booted up, i watched the internal storage's contents through windows explorer. I cried in joy when i finally saw the folders get created appropriately (dcim, downloads, etc.). but when I proceeded to select the phone's language, i got the message that the camera and gallery apps had stopped working. As soon as that happened, i fell in great pain as the folders had disappeared from the internal storage, which was again empty. What is going on here????
Nevermind, I solved it. Had to fix (e2fsck) the /persist partition (never heard of it before) and voilá - everything went back to normal

[Q] Stuck in Lollipop flying dots,Flash Kitkat gives no external storage & no service

[Q] Stuck in Lollipop flying dots,Flash Kitkat gives no external storage & no service
My device is a Nexus 5 32GB.
It was on Kitkat but I updated to Lollipop a couple of months ago, and everything was running with no errors.
This week when restarting the phone, it got stuck on the flying dots boot screen with nothing working to get it going.
I tried wiping Cache, Dalvikcache, Data, Factory reset but no effect.
I reflashed Lollipop original ROM using adb/fastboot but no use.
I flashed Cyanogenmod 12 but it got stuck on its own boot screen.
I flashed Kitkat original ROM and it got past the boot screen and worked, but most applications do not work (example: Camera, Gallery) and give a "No External Storage Error". I also have no Service (no phone, no mobile data), SIM card cannot be detected.
Again I tried wiping Cache, Dalvikcache, Data, Factory reset but no effect.
I downloaded the Lollipop OTA update but it got stuck on flying dots again, so I reflashed Kitkat.
Now I have no service and no external storage detected again.
I am unable to install any apps from the Play Store.
Please help

When you flash back to KK, did you flash userdata and cache ? If no, do so.
What do you call external storage ? N5 only have internal storage.
Then I would say, follow this tutorial if you didn't try it already : http://forum.xda-developers.com/showpost.php?p=47156078&postcount=2
It's help me when my phone won't boot up after downgrading from L to KK

[Q] Nexus 5 stuck in lollipop boot screen!

So I had my phone charging and it suddenly rebooted itself, and it just got stuck in the google screen(the 4 flying color circles)
I have tried going to recovery mode, clearing cache, factory reset and no luck, still stuck on that animation.
I ended up flashing Kitkat and camera, google app store and gallery don't work, but the worst is that it doesn't recognize the sim card, also cant download anything,or store and transfer files between computer to phone, so its pretty much useless on kitkat, I tried every version of kitkat, and clear cache everytime, as soon as I try flashing stock lollipop (any version) it goes back to getting stuck in the flying color circles boot animation.
Any help is appreciated
