Google Nexus 5 :: Backup Bootloader Before Flashing To Lollipop Or Marshmallow

Feb 23, 2016

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.

Google Nexus 5 :: Why Can't Access Recovery Mode From Bootloader

Nov 28, 2014

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 ( )
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)

Google Nexus 5 :: Can Get Into Fastboot But Shuts Down After Google Logo

Jan 15, 2016

So, originally the problem was the phone's screen was going black straight after the Google logo, I had a hunch that it was a fault with just the screen as it was pretty badly smashed and seemed the phone was running in the background and you could get the backlight to come on. Then all of a sudden it would stop doing it and then start again intermittently.

I flashed to 6.0 to see if might be some random ROM error, but still exact same problems. Screen came back and then went again. So I grabbed a new screen and swapped out the part. Now at least I don't have a smashed screen and faulty digitizer.

Now the problem appears to be slightly worse. The phone gets to the Google logo again now but now it completely shuts down after it, but it still gets to fastboot! (Is fastboot stored on another chip than FW? If so that worries me.)

Huawei Nexus 6P :: ADB Doesn't See The Phone In Fastboot Mode

Oct 31, 2015

I'm trying to flash a TWRP, but for some reason the phone doesn't show up any more in adb when in fastboot mode (at the bottom of the phone screen it tells me to connect a USB cable). It was showing fine until yesterday. I have tried several different USB ports. The cable is definitely working (in fact plugging and unplugging it causes Windows to notice and make a sound, and also it works fine in ADB when the phone is booted up.

The only thing that I can think that happened since I had last connected to it in fastboot mode (to unlock the bootloader) is that I connected my PC to a couple other phones (Galaxy S3 and Nexus 5) using them in MTP mode. I have reinstalled Google and universal drivers several times, deleted the device from device manager, etc

Google Nexus 5 :: Update To Marshmallow Using ADB / Fastboot?

Nov 30, 2015

I tried to update my Nexus 5 to Marshmallow using ADB/Fastboot and Googles images. I have followed a number of different (yet the same) approaches to flash the unit and NOTHING works. I tried to go back to 5.1.1 and can not restore the unit. It has not bricked (yet) and not sure what to try next. I have read options that call for reformatting parts of the operating systems but fearful this will brick the unit. I have flashed the bootloader, phone, recovery, userdata, sys, etc., and nothing works. I know others have had trouble with Nexus 5 based on what I have read however to date not be able to restore the device.

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 :: Power Button Stuck - Can Only Get To Fastboot

Dec 25, 2015

My N5 has a hardware fault where the phone thinks the power button is permanently pressed, so as soon as you try and boot it, it turns off again.

I am able to get to fastboot, by holding down the volume down button and power. But from there, I cannot boot to recovery or normal system boot.

I have been unable to fix this, and I really want to get some of my app data off. Is there a way of extracting a backup somehow from fastboot? I'm guessing no, as you can't access via adb through fastboot?

Google Nexus 5 :: Fastboot Wipe Cache Partition Very Slow On 6.0?

Oct 20, 2015

it takes about 5 - 10 minutes to perform a wipe from Recovery, where in Lollipop and before, it was a few seconds. A couple of websites have corroborated this.what's changed in 6.0 that a cache wipe takes so long? I'm on an unrooted N5 and performed a clean factory flash (and re-locked the bootloader).

mkfs -t ext4 /dev/[device]
rm -rf /cache/*

Or something, I mean, even formatting a heavily encrypted partition shouldn't take that long (especially one as small as /cache).

Google Nexus 5 :: Phone Stuck At Bootloader?

Oct 18, 2015

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-
Carrier Info - None
Serial Number - 047....
Signing - Production
Sercure Boot - Enabled
Lock State - Unlocked

Google Nexus 5 :: Bootloader Flash From TWRP

Aug 18, 2015

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.

Google Nexus 6 :: Restarting Phone Into Bootloader

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?

Google Nexus 6 :: Is It Required To Unlock Bootloader To Root?

Aug 29, 2015

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.

Google Nexus 5 :: Screen Garbled After Bootloader Flash

Jul 10, 2015

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.

Google Nexus 5 :: Bricked Phone - Cannot Unlock The Bootloader

Oct 1, 2015

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.

Google Nexus 5 :: Don't Start Anymore - Can't Access Bootloader Or Recovery

Jun 1, 2015

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?

Google Nexus 5 :: Why Does It Go Straight Into Bootloader After That Shows Black Screen

Mar 26, 2015

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.

Google Nexus 5 :: Won't Load Into Recover From Bootloader After Flashing Stock 5 Or 6

Oct 29, 2015

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..

LG G3 :: How To Get Phone Out Of Fastboot Mode Started

Jan 26, 2015

Was in the process of restoring the phone to factory settings (was rooted), and something went wrong and now it won't even let me boot to recovery. The phone is only softbricked, however, because it I hold power+volume down x2 it allows me to enter the factory hard reset menu.

Unfortunately, the menu does nothing, because after choosing either option it goes straight to the "[#####] Fastboot mode started" message, each time with a different number next to it (in the brackets). I've googled for days, tried running adb from my computer but the computer doesn't see the phone, even with the latest drivers. LGFlashTool doesn't work because I can't get into recovery.

Pic (obvously) is the screen it always goes to. Low quality because of the iphone camera. I really love my G3 and don't want to have to go back to that

Phone is the Sprint G3 LS990
