Google Nexus 5 :: Cache Messed Up - Unable To Boot Or Flash

Jul 12, 2015

Yessterday my Nexus 5 battery drained out and instead of shutting down, it tried to restart and got stuck in the startup sequence with the dots floating on the screen. I went into bootloader mode and then into recovery mode where I saw the cache errors.

E: failed to mount /cache (invalid argument)

I started to read a bit more on fixing the issue and the first solution was to flash it with the stock cache.img. However, when I unlock the OEM using fastboot oem unlock and reboot the boot-loader, it is going back to the locked state. I'm not sure if I'm going wrong somewhere but I haven't been able to flash my phone yet with the stock rom.

Jul 10, 2015

My device:
Nexus 5 - hammerhead D821(H) 16GB
BL version - HHZ12h
BB version M8974A-
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.

Google Nexus 5 :: Phone Won't Boot

Oct 28, 2015

updating my Nexus 5 to marshmellow has left it stuck at the boot animation. I can get into recovery and have flashed factory 5.1.1 and 4.4.4 images but all that changes is the device loops with older boot animations. Kwongger's NEXUS 5 Toolkit v2.2 completed successfully but didn't improve anything. Trying to flash Cyanogenmod I run into adb "unauthorised". The device had usb debugging enabled and the RSA key of the PC was accepted but after multiple factory resets it appears to be gone.

Google Nexus 5 :: Red Led - Doesn't Boot

Nov 17, 2015

I have a Nexus 5, all up-to-date and stuff. Now recently when I was driving somewhere it turned off. Since then i haven't been able to turn it on again.

Without charger it doesnt even go on, With the charger it gets to the google logo and then reboots over and over again.

Fastboot just the same thing. Shows the fastboot GUI and reboots. Only with charger in.

Is this a hardware or software problem? I could try something on linux but if it's a hardware problem i'll just stop to try to find a solution.

Google Nexus 5 :: Phone Won't Boot

Nov 16, 2013

My phone shut off unexpectedly today and now won't turn back on. When I try to power it on I see the Google logo for a couple seconds and then it'll just shut off again. I tried holding the volume up/down buttons to access the bootloader, but right after I get to the screen it just restarts itself again.

Connecting to power (AC or USB) causes it to constantly reboot over and over, it just shows the Google logo for a couple seconds and then restarts again.

Google Nexus 5 :: Can't Boot And Restarts Constantly

Sep 30, 2015

Bought a Nexus 5 about 6 months ago USED. It has been amazing. I got the latest OTA a week ago or so, not sure if that has anything to do with current issues.

About 2 days ago started randomly restarting. Today, it shut down and has been in continuous loop restarting. I see "Google" and maybe even the boot dots loading, then it is off. Three seconds later, starts again and repeats. Never makes it all the way into Android system. I let it sit for a while and when I pick it up, without touching any buttons, it repeats all of this. I suppose it is probably dead in general, but I don't know.

Never rooted, never messed with, always been stock,....

Google Nexus 5 :: Optimizing Apps At Boot

Sep 23, 2015

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.

Google Nexus 5 :: Camera Shutdown (won't Boot Up)

Feb 19, 2015

My issue is that when I take a photo on my Nexus 5 and it is under around 60% of battery it shuts down, the screen just goes black (phone is complexly off and dead) and the device will not respond to ANY input until it is plugged into a power source, then it will boot up and function normally.

This issue occurred about two weeks after I installed Android 5 however I do not believe it is related due to factory resets, different roms and the issue is still persisting. When the problem started I had recently (a week or so before) moved to Germany, my initial thoughts were that the battery was the problem as when it first happened the phone rebooted and only had 5% left even though the device had around 50% before I took the photo, from then on the battery life was terrible so I purchased a new battery and installed it.

The battery problem was solved (battery life was normal) and when the phone crashed it didn't boot up with any difference to the percentage of battery that was remaining. I am now thinking that something to do with the change in power supplies damaged the device. I think this is unlikely though as Australia (where I am from) and Germany (where I was when the issue started) both run on 240V, the stock power adapter was used just with a euro adapter. I have tried to collect logcats however I can't see any errors before it cuts off (I'm no dev by any means so I could be missing something)...

Last thing is that this issue NEVER occurs when the device is charging so I'm thinking that it is a hardware problem. And of course the phone is out of warranty.

Google Nexus 5 :: Why Won't Boot After Battery Replacement

Jul 26, 2015

I recently bought a new battery for my Nexus 5 due to issues I was having with my old one. When I put the new battery in, the device gets through the boot, but begins turning off as soon as the lock screen appears. Putting the old battery back in makes the device work fine.

Google Nexus 6 :: Boot Time 1:45 Minutes?

Mar 15, 2015

My Nexus 6 has random restarts about once per day. The most frustrating thing about it is that it takes 1:45 minutes (105 seconds) to reboot. It's the same length of time when I turn the phone off and boot it by hand. Is this normal? Can a few of you do me a favor and measure how long it takes on theirs?

Google Nexus 5 :: Stuck At Boot Logo

Jul 31, 2014

I now have my nexus 5 over 8 Months and everything worked perfectly but since yesterday it stuck at the google logo. I don't mean the Boot animation, I mean the first logo which shows up after booting. After 3 seconds it shuts down and i get the same. Before this happened I just recently flashed PA Rom (4.5,3) and then afterwards the newest franco kernel by the Updater App.

First everything has worked very well, but then some strange things happened to my nexus. So it just has switched the Date and Time to 1970, Google now said it isn't supported in my country (even it is), whats app needed reauthentification and also didn't automatically recognized my county, my battery has dropped while charging from 12% to 39% within a minute and then the random reboots appeared. after the 4th one I suddenly landed at the point where I am now. I also tried lots of things like going into bootloader/ recovery and flashing an old factory Image but every time I try to it kicks me to the Google logo.

Google Nexus 5 :: Doesn't Boot Up / Only Fastboot

Dec 30, 2015

Recently, I was trying to replace old battery in my Nexus and something went wrong. The battery wasn't replaced but the phone didn't boot up. When unplugged, the phone didn't react at all (and I know that battery % was enough). When I plugged it in, the battery indicator showed up, disappeared after a second and it was happening in a constant loop (this appearing and disappearing). I tried to boot up the phone but only Google showed up and phone turned off and the battery indicator was again reappearing.

I managed to access fastboot but couldn't do anything more (when trying to enter recovery - same thing as with booting up). Flashed stock 6.0.1 and nothing changed. The phone was sent to LG but they said the warranty won't cover that and offered to replace motherboard for price around $230 which for me is a bit too high as for this quite old phone. They've sent me also this photo (URL...). Now I'm waiting for them to return the phone and maybe I'll try with another LG service.

Maybe symptoms are suggesting something and it can be easily fixed. Right now I can't do anything because the phone isn't back yet but when it's back before giving it to another service?

Google Nexus 5 :: Stuck On Boot Animation

Dec 20, 2015

So recently for some reason my Nexus 5 gets stuck on the booting animation. I think it was updating to 6.0.1 or something but I'm not sure, because I just woke up one day and the phone wouldn't boot, and when it finally did it just gets stuck on the boot animation. I've tried to flash stock images and etc but I need an unlocked boot loader and for some reason if the phone doesn't boot completely after unlocking the bootloader, then it gets re-locked. So now my last option is to use the stock recovery to wipe data or something but when I go to the screen with the dead android guy, no combination of buttons seem to make the recovery options show up.

Google Nexus 5 :: Boot Animation Stuck After CWM Nandroid

Jun 1, 2015

My device:
LG Nexus 5 - Lollipop 5.1.1 LMY48B
Unlocked bootloader;
ClockWorkmod (not flashed - just boot on image when used);

I've made a nandroid backup with cwm. Backed Up the files to notebook via adb pull. Then, wiped factory reset (in cwm) and flashed Developer Preview of android M. Boot on android M works like a charm. Then, made an android M nandroid backup with cwm. Backed up these files to notebook via adb pull.

Then, bring back the files of first nandroid backup to device, via adb push. Pushed the correct folder to /data/media/clockworkmod/backup.

Folder content /data/media/clockworkmod/backup/1970-01-

-Boot in cwm, made a wipe factory reset (in cwm).
-Flashed again 5.1.1 image files (boot, radio, bootloader, system and cache).
-Reboot in cwm.
-Now, restore nandroid backup (the 5.1.1 one).

Everything looks good, and no error messages by now. But when reboot, I've got a stuck on logo animation. It took a half hour or more, and nothing. There’s nothing to do about it.

I tried found a solution, but the main thing I've heard is to flash 5.1.1 again. I did it, and works. I can bring back to a brand new installation. But I can't use anymore my nandroid backup.
