Google Nexus 5 :: Reflash Stock ROM Via Bootloader
Dec 13, 2015
my Nexus 5 has recently run into a problem where it suddenly decided to get stuck in a bootloop. I figured I could just reflash the stock rom via the boot loader with the wugfresh root toolkit but that unfortunately didn't work. But by doing this I noticed that my bootloader was not staying unlocked when I try to unlock it. Every time I unlock the boot loader and it restarts the bootloader automatically re-locks. I then proceeded to try and manually flashing the stock rom files individually and unlocking the bootloader each time I flash a file which was really annoying. It still hasn't worked and I'm starting to get worried because I've also started to notice my recovery can't really factory reset or wipe the cache. Instead I get this message at the bottom of the screen:
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/log
E:Can't open /ache/recovery/log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_log
E:Can't open /ache/recovery/last_log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_install
E:Can't open /ache/recovery/last_install
E:failed to mount /cache (Invalid argument)
So now I'm completely stumped, could this be the end of my Nexus 5?

I have flashed various version 5 stock firmware's and the latest 6.0 using nexus tool kit, as well as specifically flashing only stock recovery using the tool kit and I cannot load into the stock recovery. I've spent hours looking for information on manually flashing the stock recovery without the tool kit but have found the instructions very vauge. Any information on flashing manually only the recovery would be very useful or information on why I may be having this issue.
I know every time i flash a rom it only shows about half of my internal storage. I have a 32gb version. So I end up having to go into a recovery "temp flashed" using the tool kit in order to clear some information and then i get my 32gb's back.
I"m wondering if the space being auto allocated or partitioned is interfering with the flash of the recovery..

Is it possible to unlock bootloader, root, flash twrp and somehow flash the stock rom? If yes, where can I get the rom files for flashing with twrp?

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.

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

I was trying to install a ROM and things got a bit messed up. I wiped system/cache/dalvik/data via TWRP. I then went to install the ROM but it failed due to only supporting hhz12h bootloader.
So now I'm kind of stuck. I can't update the bootloader because fastboot/ADB won't list the device in TWRP. Is there any way to launch an ADB server in TWRP so I can fastboot the bootloader? Doesn't look like there is.
If there's not: Is there a TWRP zip-install hhz12h bootloader I can use? Looked around, couldn't find one.
If not I'll have to try and find/flash the original image..but fastboot is not going to happen so I have to find a zip installable one that'll work with hhz12d bootloader...which hopefully is around. Otherwise I could install literally anything just to get an ADB server so I can fastboot the hhz12h bootloader in there.

so I was trying to flash the latest Nexus build to my Nexus 6, but the bootloader was taking 10+ mins to flash, so I tried closing out of cmd and then restarting my phone into bootloader. Unfortunately, now, my computer doesn't recognize my phone, saying that the drivers are no bueno, so that when i type fastboot devices nothing shows up.

To unlock the bootloader in order to root the Nexus 6?
I don't really care about custom ROMs, but there are a few root apps I would like to use.
For example, I'd like to enable touch to wake. That would make the phone perfect for me.
But I just do not want to brick the phone.

just updated my Nexus 5 to Android 5.0 -- things looking smooth
went to root it
step 1) enable developer mode
step 2) restart into bootloader
step 3) fastboot flash recovery boot.img ( download.chainfire.eu/580/SuperSU/nexus5-hammerhead-lpx13d-kernel.zip )
step 4) reboot into recovery mode...
step 4 is where things get funky, when I tell bootloader to load recovery mode the phone restarts and then boots normally.I've been hacking at this for a few hours, and ended up loading the boot.img file more than once (see steps below) -- the original attempt worked and would access recovery mode the "load from zip" option wasn't available to I started tinkering, at one point I told it to restart from recovery mode -- it listed updating 7 files after which it had flashed itself back to factory defaults.I then flashed the boot loader a 2nd time it stopped accessing recovery mode
since then I've tried
- download Quick Boot app (crashes when trying to load recovery mode)
- flashed with fresh factory image
- numerous attempts to restart into bootloader
- voodoo chanting (not really but that's next)

I downloaded the Android M preview 2 and while flashing the bootloader with:
fastboot flash bootloader bootloader-hammerhead-HHZ12h.img
fastboot reboot-bootloader
after the reboot the only thing my screen ever displays is garbled colored pixels even after pulling the battery. Fastboot still works just fine, so I tried wiping everything and reflashing but it still never shows anything but this screen. I even tried reflashing older versions of the bootloader and nothing works.

My nexus 5 just turned off and is stuck on the boot animation. I am able to access the bootloader and have already tried to wipe cache and performed factory data reset but the phone is still stuck on the boot animation. I have tried to unlock the bootloader with 1-click-nexus-5-bootloader-unlock as well as CF-Auto-Root-hammerhead-hammerhead-nexus5 tools but after I accept to unlock the bootloader, the phone reboots and gets stuck on the boot animation. The bootloader status remains locked.

I've a Nexus 5, stock rom 4.4.4, rooted. Since 3 or 4 days I have unwanted reboots. And today, my nexus powered off and didn't want to reboot.
Even I press the power button for a long time (more than a couple of minutes) , nothing happened. The only thing I got, is when the device is plugged on usb charger : the nexus boot on the google logo then switch off and boot again on the google logo then switch off again and again and again....
I can't access bootloader or recovery... If the device is bricked, I just want to recover my. Is the flash memory could be recovered?

Is it possible to make a backup of bootloader? If it is, how? I am not talking about kernel (boot.img is the kernel, correct?), system, recovery, or data. Bootloader.My Nexus 5 came with bootloader version hhz11n. The factory image from Google (4.4.4) has bootloader version hhz11k.
How different these two are, but since hhz11n image can't be found anywhere, I want to back it up before flashing to Lollipop or Marshmallow.
My Nexus is still running 4.4.4, bootloader unlocked, rooted, with TWRP installed.

So, I turned on my phone and now it goes straight to the bootloader. So, when I select "Start" option, screen turns black (can still see backlight shining though). It was sitting there for hours, but screen stayed black.
I did have a rooted phone, but I hadn't tinkered with it for about 6 months.

I forgot my unlock pattern and I don't have my device in ADM ... But the bootloader is unlocked, so I think I can install any image I want, right? Could this be a way to get into my device? So any solution to unlock my device without doing a hard reset?

My mum's N5 is completely stock - I can't believe i'm having issues with the only non-rooted device in my house!
I applied the OTA 6.0 update but when starting the phone i get a never-ending loop of "unfortunately ... has stopped" about lots of apps, and google services framework, process.acore, play services, etc
I got into stock recovery and cleared cache, no change
Any way to fix it without wiping data/factory reset?

I've been looking around, but I can't find anything to suggest root is available on the stock kernel. CF-Autoroot doesn't work for 6.0, and so far all I've found is root for custom kernels but I want all stock.

I have a Nexus 5, I removed the stock email app.
Now I need to use the stock email that comes with the device for work, but I can't seem to find it in the play store. Maybe I'm searching under the wrong name, but how I can get the stock email app back onto my device? Is the stock email even in the play store? If it's not in the play store, any good email app for businesses that uses exchange?

How do you change the icons on the Nexus 5 with stock Google Launcher? I used to use the Nova launcher b/c you could customize the heck out of it, but with the Nexus 5 I'm really happy with the stock Launcher and it's integration with Google Now. The only problem is that I can't seem to customize the options with the stock Google Experience Launcher.

I installed a custom recovery on my nexus 6 called Rastapop. Don't get me wrong, its a great rom, it's just not for me. I would like to completely revert back to android 5.0.1 because I loved it. I completely wiped the device before installing Rastapop, so I cannot simply "factory reset" my device.
I can completely handle the flashing process due to the fact that I am an experienced programer. All I need from you is the link to the Nexus 6 5.0.1 ROM, and the link to the Nexus 6 5.0.1 GAPPS (Google Apps).

When playing a song I get a white notification block saying:
"Music temporarily unavailable.
Couldn't play the stream you requested"
DONE
Been having this error on/off for a month now. Sometimes it works on wi-fi but not on cell, most of the times not at all.
Right now at home I can play from my other devices (win7-pc, chromecast, Nexus10) without problems. I can browse music fine on the phone and play moview works fine - so the account is not the problem.
All hits I've had searching gave just different settings to try with caching, dl'ing etc. They are to no avail. Tried all combinations.

I flashed a custom ROM to my nexus 5 and was using it for the last few months. But today, I decided to rollback to latest stock ROM. And I double clicked "flash-all.sh" and it failed after few seconds. I could not see what happened so I again ran the executable under terminal and seen it failed again. I just remmebered that I hadn't unlocked the bootloader before running the script. Now, the phone is not turning on at all. It only vibrates if I hold the power button for some seconds, 6 seconds actually and if I hold the button for longer times, it keeps vibrating every 6 seconds.
I am not even getting the Google logo thing.
