Google Nexus 5 :: Stuck On Optimizing Apps Page On Initial Bootup
Jul 27, 2015
Have a Nexus 5 running the latest lollipop build that has been working properly for a while (Phone is a Google refurb from November 2014, replacing my original N5 that had battery issues; Warranty expired Feb 2015)4 days ago, it randomly rebooted and then got stuck on the "Optimizing apps" page on initial bootup - would never go past a certain app number.First tried wiping cache - which didn't complete even after 48 hours.
Next tried full wipe from recovery, which worked but then shutdowns still happened.Reflashed all stock images (Phone is stock, not rooted) last night - problem still exists with random shutdown - but I can always get past initial setup; shutdown problems happen a little while later during use.Wiping cache from recovery now gives a "Could not mount /cache/" error in recovery
that there's sector(s) on the eMMC that's borked. It's a 32GB phone - is there a way I can flag off a certain sector as "bad" and put the cache partition somewhere else? Also, replacing the eMMC chip if needed (I can find someone set up for BGA work). I considered doing a file check from Philz / TWRP, but since the issue persists after a full reflash/reformat I assume that it's not a software bug.

Damnit. Something went wrong and I don't know how to get out of it.
I used Nexus Root Toolkit 2.0.7. Bootloader Unlock went just fine. Root went wrong (I think). It just sits there at the white Google logo. It never goes to the animated loading portion of boot up.
So, I stopped the process. Then went to select Flash Stock + Unroot to hopefully start over. It still stays at the white Google logo. Instructions say it could take up to 20 minutes, but I waited for about 30 and nothing happened.
So I entered Recovery. Formatted/Cleared all data and started fresh with the unlocked boot loader. I was able to flash TWRP and actually flash a custom ROM. It loaded, but the phone boot looped when I tried to flash a custom Kernel.
Fine. I went to restore a backup I made before flashing the Kernel and it boot looped. Restoring the backup did nothing and I couldn't load anything.
Loaded up Nexus Root Toolkit again, tried to root and it just stays on the white Google logo. Tried Flash Stock + Unroot and it still sits at the Google logo.
WTF. I've been doing this for a long ass time now.

I have a Google Nexus 5, that has never been rooted.each time my phone is running out of battery (meaning nearly every day because I am using Waze, a GPS app, quite often), when Android is starting a message saying "Optimizing 1 of x.. apps" and this take a lot of time (sometimes more than 10 minutes).It happens since I upgraded to a previous version of Android but I don't remember which one as is it not the latest one.Now, my phone is running Android 5.1.1 build LMY48M.

Since 5.0.1 my phone has been rebooting randomly, numerous times throughout the day. I just downloaded 5.1 (hoping that it would fix the issue) and it still reboots but now every so often after it reboots, it will say "Android is Starting... Optimizing app # of #.

I recently downloaded BBM updated version and rebooted the phone, which rendered the phone completely useless. It does not boot up, just gets stuck at the Blackberry first loading page with the status bar showing 100%.

I have a brand new Z5 Compact that cycles thru the Android is Optimizing Apps screen and then gets stuck on the Android is Updating screen.
I performed a Software Repair via Sony PC Companion. The Sony PC Companion said it completed the repair and to allow the phone to restart. It stated that it would take awhile to restart, but did not state how long. After restart the screen remained on a white splash screen. After about 3.5 hours, I performed a forced restart. This brought it back to the optimizing apps screens originally seen.

I have a nexus 5 that is less than a year old. Starting just 2 weeks ago my phone will turn itself off randomly. When I try to power it back it will either
1. keep looping through the google display(literally says google in white with black background then going completely black again) for a couples of times. or
2. Display google then shut it self off again. I have to power it back on again, and it may or may not do the same thing. or
3. start after one attempt.
For all cases after it starts it will say something like optimizing apps # out of # and I have to wait a couple of minutes for it to go through the process. The it will work normally after. On rare occasions it just starts normally doing anything weird. I've tried to take out the battery and putting it back in, didnt work.

today I installed the new android 6.0 factory image, rooted it (used the modified boot.img from the previous build) and installed supersu 2.52 and blu spark kernel. Everything good until i deleted some apps (gmail, webview, youtube and other NON CRITICAL apps, like I ALWAY DO SINCE KITKAT), then rebooted and my phone is stuck at the Google logo, not even the bootanimation shows up.. Tried to reflash the boot.img, wipe cache, wipe data, factory reset but nothing.. The only thing that worked is to reflash the factory image! What am I doing wrong? Happened 2 times in a row so something must be wrong.. Another thing, I can't access TWRP every time, sometimes it skips and boots directly..

Like others, I tried the software update, and then my phone constantly got stuck at the four little circles at start up. I followed some instructions I found on AndroidPit:
1. From a powered off state, press the Power button to start your Nexus 5. When you see the Google logo press and hold the Volume Down key and release when the device vibrates.
2. Use the volume keys to highlight Recovery Menu and press the Power button to select. This will bring you to a screen with an Android on its back.
3. Hold the Volume Up key for 5 secs then release and a new menu will appear.
4. First off, you can use the volume keys to select Wipe Cache Partition. This will cause your phone to restart. once this is done, re-do the previous steps to get back to the same screen (the one that Wipe Cache Partition was on).
5. Highlight Wipe Data/Factory Reset and select using the Power key. Scroll down to Yes, Delete All Data and press the Power button again to select.
6. Your Nexus 5 will now wipe your data and reformat.
7. On the next screen hit the Power button to select Reboot System Now.
It has been 40 minutes now and it's stuck on 'Formatting /data'. Is this normal?
I've only had this phone for a couple of months and it was functioning perfectly until now I haven't rooted it or anything.

So this morning I woke up to my phone on a boot loop on the Google Logo. I have no custom roms or mods on it other than I am running ART. I suspect it could be battery related as it will only seem to do this on the charger but when I don't have it plugged in it won't even start up. When it's plugged in it won't even seem to want to stay "off", it boots up to the google logo on its own. If I hold down the volume rocker I can get into the bootloader but it resets before I can select anything and boots right back into the google logo.

Just wanted to upgrade my sisters phone which was running an old 5.1 version (custom rom, so the phone was unlocked and rooted already) to an android 6.0.1 custom rom. So I flashed newest twrp and flashed 6.0.1 bootloader and radio.img via fastboot using wugfresh tool and the files from the thread on here. now when trying to get into recovery, I am stuck at the google logo.

My device:
Nexus 5 - hammerhead D821(H) 16GB
BL version - HHZ12h
BB version M8974A-2.0.50.2.26
Secure boot enabled
lock state unlocked
Today I got a "broken" nexus 5 that is in boot loop with the google logo and it wont boot into any .img
At the start i read the pinned posts and found this tutorial: [URL] ...
followed it step by step. but unfortunately it didnt work in my situation. there werent any errors or such kind. I also tried this tutorial with other images but nothing worked.
When i go to the recovery mode and press the power button the phone get into the google logo and i can see some sort of strange stripes in like a milisecond but then it just gets into the boot loop.
i really think ive tried everything accept for relocking the bootloader but cant imaging that this could be the problem.

There is a similar post entitled " PC recognizes Nexus but then I can't access my storage". None of the solutions offered seem to apply to my situation. This is a new problem for me as I have previously had no difficulty connecting to my PC transferring files, especially music files.
Windows 7 on PC, Android 6 on Nexus 5. I am not rooted.
One solution mentioned in the other similar post said to go to:
Settings|Storage and USB|3dots| Menu in the Upper R Corner| USB Computer Connection is MTP
When I click on the 3 dots all I see is the option for "help and feedback". Not useful.
Accessing the device manager on the PC shows the Nexus 5 under portable devices. Clicking to update drivers shows the drivers are up to date.
Looking at "Devices and Printers" shows 2 Nexus 5 icons. One is described as a portable media player. Clicking on it brings up the blank page. The other icon under properties lists the device as a phone. Double clicking on the icon brings up Bluetooth operations which shows PC<->BT<->Nexus 5. I currently have Bluetooth turned off on the Nexus 5.

I was sitting down with my nexus on my leg with about 40% battery left when it suddenly turned off and then flicked to the google startup page before going blank. After attempting to turn it on again (to no avail), I resorted to plugging it in, which resulted in the phone looping on the google page then vibrating before repeating. I tried to get it into the bootloader menu, but it appeared and then reverted to the google page after the phone vibrated.
I've tried looking up solutions, but the only plausible situation for me seems to be returning it so the warranty can take over. The only hitch with that being that the bootloader is unlocked (not rooted, just the bootloader). I really am stuck, and do not know what to do

I bought an E6-00 just one and a half month ago. Although its operating system kept restarting itself since the first time I bought, I did not care much about that as the phone was running ok after restarting itself. However, it finally gave a disk error yesterday and stuck in its main desktop screen. Then I turned the device off and when I turned it on again, it is stuck in the initial white screen where a Nokia logo was supposed to appear. Nothing happens then; the white screen persists until the battery is empty.

Ever since I have unlocked my bootloader I have 2 things that bug me.
1. Whenever I restart my phone it asks for my password/pin/pattern everytime before it will start. It's not a huge deal except when I restart my phone and forget I have to do that part it sits a while waiting for the password.
2. The little "warning" screen that tells me my bootloader is unlocked. Just like the way the old Nexus's were with no warning, just the little white unlocked pad lock on the google screen.

so I accidentally wiped the entire phone and tried to install chroma rom. Now after boot I'm getting an "Encryption Unsuccessful" message. and its asking me to reset phone.
I tap the Reset Phone button and I am taken to TWRP where it asks for a decryption password. I enter "default_password" and the phone reboots with the same issue.

Ok so if your phone reboots or crashes, you will need to enter a password or pattern in order for the phone to work. Even alarms and everything won't work until you enter the password. That's pretty bad especially if you NEED an alarm
Some people mentioned turning it on and off and it would give you a prompt to disable it.

I got an apk file of the new Google Now Launcher which is an official launcher by Google and I couldn't find how to hide useless apps which cannot be uninstalled.
Is there a way to hide them? I thought I should post here if the Nexus 5 users know how to do it.
I have a Samsung Galaxy S2 Plus GT-I9105. It's not rooted and I never will.

My Nexus 5 is stuck at the flying dots after Lollipop OTA update. Already try factory reset. Cant connect to my Lap (running Windows 10) because it says in the device manager: Unknown USB Device (Device Descriptor Request Failed), so I cant manually update the driver and cant access it with ADB and Fastboot tool. The device has no USB debugging enabled. In the old computer where I used to connect the device and has the drivers installed says the same thing in device manager as my new laptop.

For about two months now I've had an app stuck in recents, and no matter what I do it won't go away. It's basically a website I opened from a google search. I've deleted and reinstalled Google Now, the phone has been upgraded from 5.1 to 5.1.1 in between, restarting, nothing seems to do the trick. I've been googling the problem without success so far.
Here's a screenshot: [URL] ....
Nexus 5, stock 5.1.1 ....

Got the Marshmallow update this morning, phones been good for about 14 hours and now all of a sudden while updating apps the phone re-started and has been re-starting ever since. It goes through boot-up screens to the "hand stitched" screen and then shows me a small message indicating it is optimizing 1 of 27 apps like it is doing an upgrade, it will sit on that for a few seconds and then the screen just goes black. After a couple minutes the process starts over again all by itself. It has been sitting here on my desk doing this for about 45 minutes now. Looks like I was able to experience Marshmallow for about a day, going to have to head back to the Nexus 6 (with no Marshmallow yet) and get a hold of Moto.

I have a nexus 5 that I was preparing to hand down to my wife. I had transfered everything over to my new phone, and initiated a factory reset. It rebooted to the "erasing" screen, and sat there for about 20 minutes, before switching to the dead android screen (w/ red triangle.) I thought that was odd, did some searching, and tried the recovery mode from the bootloader. That produced the same results. So now I'm stuck.
From the boot loader I can access the following options:
Start -> Erases for ~20 minutes, then dead android
Restart Bootloader -> Screen goes blank, phone vibrates, and then back to the bootloader screen
Recovery Mode -> Erases for ~20 minutes, then dead android
Power off -> turns off the phone
I called Google, and the tech support hadn't heard of anything like this. Because it's almost two years old, he transferred me to LG's tech support, who basically said find a local repair shop, or they could RMA it for an unknown cost.I'm pretty sure the phone is bricked at this point, which is frustrating, because it was running stock android - completely unmodified. I think I might have rooted it once, months ago, but I can't imagine that that would have caused this issue. I had even received and installed Marshmallow OTA, and it was running perfectly.
Anyway, some program I might be able to use on the PC to regain access to my device.
Literally the only information I can provide about the phone at this point in time is as follows:
Product_Name - hammerhead
Variant - hammerhead D820(H) 32GB
HW Version - rev_11
Bootloader Version - HHZ12k
Baseband Version - H8974A-2.0.50.2.27
Carrier Info - None
Serial Number - 047....
Signing - Production
Sercure Boot - Enabled
Lock State - Unlocked
