[HELP] System Crash - Nexus 5 Q&A, Help & Troubleshooting

I have a 32GB Nexus 5. Yesterday, I made a backup, then attempted to flash this stereo mod. After reboot, the launcher stopped. I attempted to go into the settings via recent apps menu, and SystemUI crashed. I flashed the stock mixer_paths.xml file, rebooted, same thing.
I restored my backup, and oddly enough, it still didn't work. I followed this guide to flash the factory image of LP, and even after the factory image, it still crashed. I installed the task manager I normally use, noticed that it didn't show any processes. Literally says 0 Processes, 20 services.
What could be the issue? Any way to fix?
Edit: Problem solved.

Nothing works, everything crashes, can't do anything.

After updating to the latest firmware via OTA, everything crashed.
Every, single, app. Even the system gapps. Only things that worked: Settings, Browser, File Manager
So I factory reset, figuring it would work.
Nope, Now I cannot even complete the setup.
At step 5 I get Unfortunately, the process com.google.process.gapps has stopped.
Then it goes back to step 1 of the setup.
I am NOT unlocked which is why i have no freaking idea what to do.
Thanks.
Fixed it using fastboot.

[Q] Help! I tried to root my tablet and now I seem to have broken it -- it won't boot

Alright, so yesterday I tried to root my tablet (Samsung Galaxy Tab 3 10.1 Wifi) yesterday by installing TWRP and then loading the Superuser zip found in their link in the play store. It worked fine--I had root access and all was going fairly well. I then tried to make a small tweak to the build.prop file by changing ro.build.version.codename from REL to L.
When I rebooted to apply that change, I could not start up, so I did a factory reset (not a big deal, no essential files on there). It then booted fine, but when I reinstalled/updated all my apps, the Google services were crashing like mad. So I reverted the build.prop file back to REL and again it would reboot, so I did another factory reset and all was good; the Google apps were fine.
Well I was still rooted and I wanted to take advantage of all that time I spent doing it, so I downloaded the bootanimation zip found on this thread and replaced my bootanimation.zip that was already on there. I restarted to see the animation, and this is when the real nightmare started happening. I could not boot now at all.
I did another factory reset, and still it wouldn't boot. I then used TWRP to do a full reset, and still nothing. I did an advanced reset and somehow managed to delete the operating system files (I have no idea how), causing TWRP to say that no operating system was installed. I still couldn't boot, of course.
Finally, I decided I had had enough of this rooting ****. I searched all over the internet looking for a North American version of my stock ROM, and finally found one posted on this forum post. I wouldn't normally trust any random file, but I was getting desperate here. I used Odin to flash that ROM, and there were no errors. Now when I go into recovery, it gives me stock and not TWRP, so I know that was probably successful.
However, I still cannot boot. I get stuck on the screen that says Samsung Galaxy Tab 3, which sometimes goes away and then comes back. I can't send it in for warranty, because it still says "custom" in the recovery mode. How can I fix this? any ideas?
I really want my tablet back :crying:

Major problem with phone after (botched?) stock restore

I'm truly lost for how to fix this. I'm trying to restore my phone to factory and I've wound up with major issues with the phone when it starts up. I get immediately those messages you get when a process dies: "Unfortunately, the process com.google.phone has stopped." I get this message for a huge range of apps, as far as I can tell it may be all or most of the built-in system apps, one after the other. I can't access settings or anything.
I tried restarting into fastboot and using "flash-all.bat" to wipe everything and install the stock images, then booted into recovery and attempted to wipe the data. I got everything wiped, or so I thought, but then the same problem still occurs when it starts up. How is this possible? Surely there could be nothing remaining of the old system on there at this stage?
After you flash factory images, there's no need to go in recovery again. Also, when setting up google account, don't sync app data.

[Q] Issues after upgrading to LMY47I

Hi All,
I did an upgrade to 5.1 (LMY47I) on my Nexus 5 and started facing some strange issues and have no clue on how to resolve them. Before the upgrade I had the following config:
Recovery: TWRP
Root status: Rooted
ROM: Stock 5.0 LRX22C
I used following method for the upgrade: http://forum.xda-developers.com/goo...e-update-rooted-device-to-5-1-lmy47d-t3050789
It was successful but post that I came across few issues as below:
1. Power button functionality was erratic. Sometimes it would lock my mobile but at other times it was locking and waking up my phone immediately. At times "Power Off" popup was also showing up. While I tried to figure out reason for that, trying power button multiple times, my phone rebooted and started the "Optimising Apps" sequence once again. It happened again a couple of times and so I decided to try out factory reset (since I hadn't done that after upgrading).
2. I did a factory rest from Settings. After factory reset, apps and other settings were gone but I noticed that user data in the storage was intact. I guess that also gets removed on a factory reset. Am I wrong on this one?
3. I wanted to install Cerberus as a system app and so I downloaded its zip from the website and flashed using recovery. I was surprised to see that the app wasn't showing after booting up. I tried couple of times more but got no success. So, I decided to install it from Play store and convert to system app using Link2SD. When I tried doing that, Link2SD gave me an error saying "/system: not enough storage space". I tried converting few other apps but got same error. Any thoughts on what could be going on here?
Thanks,
Anurag

1- Possibly hardware (power key) issue
2- Factory reset from Android OS *should* erase all user data.
3- Its just that, /system does not have enough free space to put more apps in there. Common issue after Lollipop. Remove some other app from /system, such as Maps, for example, to free up some more space. Be reminded that once you start messing with /system, this will (or might) cause issues with OTA updates.
So I managed to tackle (or at least figured the reason) for all the issues I was having:
1- Yes, there is some issue with the power key. ? But the other issue of optimising apps loop was because I did not do a clean install which disappeared when I did the factory reset after that.
2- After doing some reading on the Internet, I came to know that stock recovery cleans the user data but twrp doesn't by default. Since I had twrp, it just removed apps and settings but retained other data. In order to do a clean install I flashed stock LMY47I again including recovery, userdata etc. (used flash-all.bat). This removed everything from storage and made my phone as good as a new one (software wise).
3- Yes, it was the issue with storage space and was a surprise for me. Thanks for clarifying on that. Before I did a clean install, I tried removing couple of system apps and was able to install cerberus after that via recovery too. However, clean install solved everything.. ☺

cannot enter twrp recovery mode. please help

I tried to remove Uc browser from my system. For some reason when i uninstalled it it fully crashed my system. Previously i had inadvertantly removed some of the cached files in its internal app folder. I tried then to uninstall it by using an app called Root Application. Still did not work. So tried reinstalling by directly going to website to get the apk file. Reinstalling was success but uninstalling or launching the app still crashed my system. Even going to app manager under setting to force stop it would cause system reboot.
Then i found out that i could not even go into recovery mode of twrp v.3.0.2-1. So i downloaded latest twrp for my p5110 v3.0.3 to try out. It seemed that it has replaced my older version since i could see the new version number but it still would not go into it. Right after i saw the splash screen it would go back to boot.
I tried going to setting and reset my tablet but everything seemed to come right back to original state. Nothing got wiped or cleaned, which i suspected it crashed before even getting to that operation.
Everything else seems to work with the machine. I could uninstall other app. I really do not know how to approach this problem. If i cannot go into recovery mode. What could i possibly do to revive my tablet.
Should i just use odin to flash a stock rom back? Would that wipe out twrp as well?
Please give me some suggestion.
are you going into recovery by holding the power button and volume down just checking
I did some experiments and here what i have found so far.
1. Uninstalling ub browser app will reboot it by any means.
2. I have managed to replace twrp with cwm. When i go and try to reformat /data partition it will reboot it as well. No factory reset can accomplish
3. Bring up application manager and while it computes statistics of memory usage it will reboot it
4. Test memory using emmc brickbug check app says all 16g healthy and problem free and it found no emmc bug saying it is sane
My next trial would be to flash back the stock rom but i am so afraid it will crash it while being flashed given my experience above.
Right now the machine seems to function well in all aspects. I suspect it is infected or some nand flash is damaged but not sure what that would be.
I won my battle. Here is what i have done. Revert to stock kernel to wipe over old system partition then whereupon i was able to factory reset the data partition. I suspect oc browser is playing havoc here since i had no way to eliminate it before i did all that. I advise against deploying it on your android
