Unable to unroll from Nougat - Nexus 6 Q&A, Help & Troubleshooting

Hey,
I enrolled to the Android Nougat program and rooted my phone (chainfire) a few days ago. Decided to un-root (using superSU), and it said I was unrooted. After doing the un-rooting, the OEM unlock-option was greyed out (and on OFF setting), but the phone recovery says it's unlocked api 3.... I pretty much just wanted to unenroll and go back to MM. Every time I choose unroll from Google, download the MM OTA and it reboots I get an error. Just an image of android with message "ERROR". The only way to get the phone working is to do a hard reset and go back to Nougat.
Not quite sure what is wrong here. Any suggestions?

It's probably because the SuperSU unroot hasn't cleaned up everything that the MM installer checks for. Your best bet is to use the sideload OTA here:
https://developers.google.com/android/nexus/ota
to install MM again. It's quick and easy, and doesn't touch your data.
Since you received the actual uninstall OTA you must have successfully unenrolled, so you should be ok from now on.

I received the OTA but while installing MM it gives me an error, so I have to go back to Nougat every time. I've tried the unenroll option several times and it gives me the same "error" every time. So, I should try manually flashing MM, then?

UPDATE:
I tried the following:
Downloaded and tried to sideload 6.0.1 (MOB30W) to my Nexus 6-device. It got up to 46% and after it gave me and error saying:
WARNING: No file_contexts. This package is for shamu devices; this is a "".
E: Error in /sideload/package.zip
Status 7
Installation aborted.
UPDATE2:
Tried another package. Didn't work. All the OTA updates stop at 46% giving me the same error. Device remains unlocked, but appears not to be rooted. Still stuck on Nougat.

What does "Tried another package" mean?
It may be that your download was corrupt. I always check the SHA with this checksum utility:
http://download.cnet.com/MD5-SHA-Checksum-Utility/3000-2092_4-10911445.html
though I've read in the instructions that the Android installation itself checks the package - it may be this error that the installation is reporting.

No, the checksum is fine. The package is fine. I mean I tried several OTA packages for N6 and it always stops at 46%. There's something else going on here. Maybe if I re-root with chainfire and the use another method to unroot it? Which is the correct method, I have no idea?

Factory reset, and try sideloading MOB30W again.

My suggestion is to go back to Android N, root with SuperSU and see if your OEM UNLOCK toggle in Developer Options is working again and not greyed out. Then I would fastboot flash back to MM and install TWRP and SuperSu.

Dude, just flash the system image you want. Forget about the OTA

The OTA is a system image.

You could say the new full otas are, but you can't go flashing them freely over newer images.
The unenroll option resets the phone anyways, so the best and aparently the only option for him is to flash the system image he wants from scratch.

Well my friend I have no idea since I'm on Windows. Google how to use adb and fastboot on ubuntu, there should be a solution for you.

This is a script that I used to run before the full OTAs became available. It worked many times for me, but the usual caveat - you follow it at your own risk. You can probably skip the backup step in your situation.
Preparation.
- Take a TWRP backup and save it on your PC.
- Download factory image and unzip all files, including the zip within the zip. Rename the *.img files to the names below. Copy all of them to the same folder as your ADB/fastboot executables.
- Download the relevant TWRP and rename to twrp.img - also put in ADB/fastboot folder.
- Copy SuperSU to device (if root wanted).
- Set USB debugging in Developer options & attach to your PC.
- Open a CMD window and check connectivity with "adb devices". If it's ok, copy & paste each command below into the CMD window and run them - the only lengthy one is the system.img.
1. adb reboot bootloader
2. fastboot flash bootloader bootloader.img
3. fastboot reboot-bootloader
4. fastboot flash radio radio.img
5. fastboot reboot-bootloader
6. fastboot erase system
7. fastboot flash system system.img
8. fastboot erase boot
9. fastboot flash boot boot.img
10. fastboot erase cache
11. fastboot flash cache cache.img
12. fastboot reboot-bootloader
13. fastboot flash recovery twrp.img
14. From bootloader boot to TWRP and reflash superSu

If I download the factory image (OTA) off google's site it has none of those files under the zip-folder.

One thing is the OTA image, and another is the Factory Image.
Download the factory image from here.
https://developers.google.com/android/nexus/images#shamu
Unzip everything and you should get all the files needed. As I said before, you would need to have a computer with adb and fastboot installed.

Just be sure to have selected "oem unlocking" in the developer options, make a backup (everything will be wiped), and start flashing!. There are several guides everywhere.

[HOW TO][Unlocked Bootloaders]Install Fastboots, CWM, Tips & Ticks, and More

Now that the bootloader is unlocked, everyone is asking "WTF do I do now?". Well, here's a bit of help to get you started. I'm assuming you already have adb and fastboot setup and working -- if not, quit reading and get that taken care of. Also, I only run Linux...so I'll try to be transparent and only list the fastboot commands.
I assume that you're not a complete moron and can Google what you don't understand.
Don't use the stock\SDK fastboot binary for flashing /system.
An updated fastboot binary for Lin\Win\Mac can be found here on the Batakang FTP from our local, neighborhood Mattlgroff.
Linux -- Rename the file to moto-fastboot and add it to a directory in your $PATH -- Ubuntu\Debian users can just add it to ~/bin (enabled by default)
Windows -- Rename the file to moto-fastboot and put it somewhere handy...that's on you to decide.
ROOT\ADMINISTRATOR INFO
On Linux, you might have to run as root in order to run some of the fastboot commands. If your system uses sudo for root commands, typing "sudo -i" will bring up an interactive sudo shell so you don't have to type sudo over and over again. If your system uses su for root, well, you already know the command.
On Windows, you have to enable Administrator Privileges to be able to run some of the fastboot commands.
Linux Terminal Hints
~/ means your home directory -- example -- "gedit ~/Documents/file.txt" would open file.txt in gedit easier than /home/yourusername/Documents/file.txt
You can add a * to file names and directories to not type as much -- example -- "gedit ~/Doc*/file.txt" is the same as the command above, only shortened. If two files have similar names, like Documents and Downloads, then you have to type the name up until the firs different character then add *.
Use the command "../" to go up\back one directory. The command is stackable so "../../" would go back 2 directories and so forth and so on.
Use "cd" to change directories. Is an example really needed for this...
Proper Apps to Use
For zip file editing, use 7-zip on Windows and Archive Manager (file-roller) on Linux
For editing text files on Windows use Notepad++ or any text editor that has unix line breaks -- do not use default Notepad or Wordpad -- you've been warned. Use what ever you prefer on Linux. I prefer Gedit myself.
Basic Fastboot Command Syntax
fastboot flash "partition" "image" -- flashes partition image where partition is where to write to and image is the path to the image being written.
example -- fastboot flash system /path/to/system.img
fastboot -w -- does a factory reset; to expedite things, "-w" can be added to "fastboot flash system system.img -w"
fastboot continue -- continue with the boot process
fastboot devices -- list devices fastboot recoginzes
fastboot -s "device model number" -- set the device fastboot will write commands to; use "fastboot devices" to find model number
fastboot reboot bootloader -- reboot phone into fastboot mode (or restart fastboot mode while in fastboot); same as "adb reboot bootloader"
fastboot help -- list all of this & more
Command Info
Not all the fastboot commands work for us. Specifically, the "erase" commands. If a wipe command doesn't work, skip it. I'll mark them with a ! at the end if it might fail.
Install CWM Recovery by Epinter
Read Epinter's RAZR HD CWM Thread
Download the recovery image
On stock rom, navigate to /system/etc and rename install-recovery.sh to install-recovery.sh.bak
Reboot into fastboot -- use "adb reboot bootloader" from Terminal\Command Prompt
Wipe the existing recovery -- "fastboot erase recovery" !
Flash the recovery with "fastboot flash recovery cwmrecovery6028-xt925_20130219-epinter.img"
That's it, CWM is installed.
Install Stock Fastboots JB
Download the respective fastboot zip you want to use
Extract the zip
Open a terminal to the extracted zips directory
Reboot into fastboot
Type the following commands in this order
fastboot flash boot boot.img
fastboot flash devtree device_tree.bin
fastboot erase system -w !
fastboot flash system system.img
fastboot -w
fastboot erase cache !
fastboot reboot
Install Stock Fastboots ICS
Download the respective fastboot zip you want to use
Extract the zip
Open a terminal to the extracted zips directory
Reboot into fastboot
Type the following commands in this order
fastboot flash boot boot.img
fastboot flash devtree device_tree.bin
fastboot erase system -w !
fastboot flash system system.img.ext4
fastboot erase cache !
fastboot -w
fastboot reboot
Install Alternate Radio
Reboot into fastboot
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot erase modemst1
fastboot erase modemst2
NON-HLOS.bin is found inside a fastboot zip.
Easy Kernel Install
Download kernel-flash.zip in the attachments[/URL]
Open the zip
Replace the zips current boot.img and device_tree.bin from the fastboot of your choice
Install the zip with CWM
By default, kernel-flash.zip comes with Mex Retail kernel and devtree
Easy CWM Install
Download recovery-flash.zip in the attachments[/URL]
Install the zip with CWM
Not sure if its SS compatible, but it is CWM compatible (for the lazy Photon Q users).
Obtain root after installing a Stock Firmware
There are two choices for obtaining root after a stock flash. the closed source SuperSu by Chainfire & and the open source Superuser by Koush.
Download SuperSu zip from Chainfire (Closed Source)
Download Superuser from Koush (Open Source)
Download the one of the root zips above.
Reboot into CWM/TWRP -- adb reboot recovery
Locate and flash the zip (see below for an alternative way)
Reboot, that's it. Nice not having to run exploits\hacks\Linux just for root
Install Rom/Zip file with ADB + CWM
CWM has the awesome ability to install zip files without having to manually copy them to the phone first. All's necessary is a PC with working adb.
Reboot into recovery
Select "install zip from sideload"
On PC, type "adb sideload /path/to/zip" and press enter
The zip will now be copied to the phone's cache & install
Once installed, do any requirements you'd normally do like wipe caches, etc
I have done this numerous times and it still will not boot into recovery. I have read and followed epinter, yours, official cwm, and other various Google found instructions (none of them functionally different) and still the same result. It recognizes the phone, writes, completes, then if I reboot and select recovery it goes to the android with the open chest cover with the exclamation point....
Any ideas how I could be screwing this up?

Unless you're not rooted with an unlocked BL, there's really no reason why it shouldn't work?

same here.
I have the same problem. I was able to flash cwm, uninstall the SS recovery, and uninstall the app. The first time I got the dead android symbol. I restored SS via Titanium Backup, reinstalled the SS recovery, and flashed cwm again. I tried rebooting into recovery and was able to get cwm working. As soon I uninstalled SS and rebooted, I got another dead android.
probably because were all on the XT926 if we were to revert back to XT925 then the recovery should work otherwise we will have to tweak the recovery to get it to work properly witht the XT926 software awesome thing is we can now free up the space that SS used for a rom slot however for noobs you might wana stick with SS once you hardbrick without anything to go back too it will be game over for your phone and then you have to con ATT for another

You won't lose root
And with an unlocked bootloader, all you gotta do is flash an updater zip with the su binary and app for Stock roms that don't have root

[TUTORIAL] Applying an OTA update with stock + root/custom recovery

Preamble
As the title suggests, I had a Nexus 5 running stock Android 5.0, with root and TWRP, and wanted to update to Android 5.0.1 (without losing all my data, of course). I couldn't find any guides for my particular circumstances, so after working out how to do it myself, I thought I'd share my method.
Note: This guide is not for the uninitiated. Be prepared to Google something for yourself if you don't understand it.
Prerequisites
Before starting this guide, you should have:
A Nexus 5 that running stock Android. The presence of root/Xposed/custom recovery (maybe custom kernels?) shouldn't be relevant, but I can't vouch for the efficacy of this guide if you've done something obscure to your install.
Android SDK tools, specifically the ADB and fastboot binaries. Additional USB drivers may be required on Windows.
The factory image for the Android version you are currently running.
1. Uninstall root and other /system modifications
If you have rooted your Android, and/or installed BusyBox, Xposed or other modifications to /system, you will need to uninstall these modifications. Failing to do so will cause the OTA to complain that there's something funky going on in your /system partition.
You may be able to manually uninstall each of these modifications, but this was not enough for my install – doing a ‘Full unroot’ in SuperSU still left behind files in /system. The easiest way to uninstall all /system modifications is to reflash the /system partition.
Extract the Nexus 5 factory image (e.g. hammerhead-lrx21o-factory-01315e08.tgz), yielding a directory with files such as flash-all.bat and image-hammerhead-XXXXXX.zip. Do not use the flash-all script, as this will unnecessarily wipe all data on the device.
Extract the image-hammerhead-XXXXXX.zip file, specifically the system.img file.
Open a command prompt/terminal window.
Connect the phone to the computer with a USB cable.
Boot the phone into the bootloader.
Method 1: Power down the phone, then hold VolUp + VolDn + Power until the phone boots into the bootloader.
Method 2: From the terminal, run adb reboot bootloader while the phone is still powered on.
From the terminal, run fastboot flash system /path/to/system.img.
2. Uninstall any custom recovery
Custom recoveries don't seem to support OTA updates, making it necessary to uninstall the custom recovery by reflashing the stock recovery.
Extract the recovery.img file from the factory image, as in Part 1.
Open a command prompt/terminal window, connect the phone to the computer, and boot into the bootloader, as in Part 1.
From the terminal, run fastboot flash recovery /path/to/recovery.img.
Optional: Reflash boot.img and/or cache.img
Some users have reported that reflashing system.img was not sufficient, and that reflashing boot.img and/or cache.img was also necessary. I did not have this problem, but if you do:
Extract the boot.img and/or cache.img files from the factory image, as in Part 1.
Open a command prompt/terminal window, connect the phone to the computer, and boot into the bootloader, as in Part 1.
From the terminal, run fastboot flash boot /path/to/boot.img.
From the terminal, run fastboot flash cache /path/to/cache.img.
3. Apply the OTA update
The simple part. In the bootloader, use the VolUp/VolDn buttons to select ‘Start’, then press the Power button, to reboot into Android. Follow the system update instructions to install the OTA update.
4. Reflash the custom recovery and re-root
Also self-explanatory.
Hey,
I just wanted to say thanks. This totally fixed the problem I was having. I also want to add that after I flashed the system.img, I was getting errors related to "EMMC:/dev/block/platform/msm_sdcc.1/by-name/boot" with a bunch of numbers after. I googled it and found I had to also flash boot.img, and after that, the OTA worked fine. I would assume if anyone else gets errors like this, they should flash whatever img it shows in the error (ie: mine said /by-name/boot so I flashed boot.img).
-BGM
It worked for me
I've always been using a toolkit for my rooting purposes, I have done Full Unroot on SuperSU, but still getting an error when trying to update to 5.0.1
Will flashing stock wipe everything(whatsapp image, camera's,messages, etc etc)on my phone?

I also had problems using ‘Full Unroot’ in SuperSU. It's not actually as ‘full’ as it sounds.
Flashing a full factory image would normally wipe everything, but carefully following this guide will only reset the /system partition, not any user data.
I'd like to say thank you very much! I was looking for this kind of tutorial... I encountered an error while following all the steps because I forgot I had a custom kernel. So I wanted to add that if you have a custom kernel remember to do the same steps as described above for the kernel (return to stock) and then follow the system and recovery steps afterwards.
If you don't like running commands in terminal you can use Nexus Root Toolkit, on advanced, you have all the commands you need available.
Thank you very much RunasSudo

I have my ADB and Fastboot ok as confirmed by nexus root toolkit, but I am not sure on how to use terminal.. I launched command prompt but it doest recognise all the commands..
Tried Flash Stock + Unroot on Nexus Root Toolkit but the software will crash (fastboot.exe has stopped responding)
I am really clueless on what to do next..

Flash Stock + Unroot wipes everything and defeats the purpose of the tutorial made by RunasSudo
First and foremost you should download Android SDK (Tools only) on http://developer.android.com/sdk/index.html and then ask to install the extra: Google USB Driver.
With Nexus Root Toolkit you don't need terminal, click on advanced and you should see options to flash through fastboot the system only, recovery and kernel. It is pretty straighforward and it asks where the .img are in your computer
Thanks! This guide worked.
For Ubuntu users, you need to install adb and fastboot with these commands :
sudo add-apt-repository ppahablet-team/tools && sudo apt-get update (optional)
sudo apt-get install android-tools-adb android-tools-fastboot
Thanks for the great step by step.
As with some of the other posters, re-flashing system.img was not enough for me, I had to also re-flash the boot.img. Once that was done, I had no problems side loading the update and am now running LRX22C.
I only seem to fiddle with adb once a year - when it OTA time comes - and can never seem to remember some of the steps that need to be taken. Reading through some of the other threads, I have a feeling a lot of people who rooted/custom recovery and cant do the OTA are going to be doing complete image re-flashes when this guide makes that completely unecessary.
thanks again,

+1 for flashing boot.img worked perfect after I did that.
I tried with this tutorial. I flashed system and recovery and then restart. Confirm OTA but I get ERROR.
Then I flashed boot as it was described. Now I don't get OTA In About phone, I'm still on 5.0.0, Check for updates now don't find update
Any idea?
UPDATE - UPDATE: After hour now it is here ... super, it works.
This walkthrough was most helpful! Ended up replacing the boot.img as well since I had ElementalX installed. My apps are optimizing as we speak. Thank you!
Worked for me. What a hassle!
Here is a summary of the process for those looking for a less wordy procedure, with a few added steps:
Download Nexus 5 5.0 (LRX21O) file (note: NOT 5.0.1 yet) https://developers.google.com/android/nexus/images
Unzip via 7-zip multiple times in order to get boot.img, recovery.img, system.img
Enable USB debugging: http://www.kingoapp.com/root-tutorials/how-to-enable-usb-debugging-mode-on-android-5-lollipop.htm
Plug phone into PC > cmd prompt where adb is installed > type "adb devices" to ensure connection is valid (will need to authorize via popup on phone > then "adb devices" should return your device id and "device"; if it says "unauthorized" then look for the popup on your phone)
adb reboot bootloader
Put system.img, recovery.img, and boot.img in same folder as fastboot.exe
Run commands:
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot erase cache (this is optional. I didn't have to do it, but you might)
Use Volume Up/Down to select Start > press Power Button to reboot
Update via Settings > About Phone > System Update

Loading problem
I flashed system, recovery & boot images strictly following the instructions, restarted the phone. It got stuck in loading where balls in four colors keep running for half an hour. Shall I keep waiting? I think there must be something wrong. Your advises are welcome.

Try flash the partitions again. If it's still not working, you may need to reflash a factory image.

Bootloop and "unable to mount data"

Hey guys,
Need some help here as I've checked everywhere I possibly can and can't find the answer. I've rooted phone then installed miui 6 rom which worked but i didnt like it. Then I tried to install my rom 3.3 and everything got fuked up. Now when i power on my phone it is in bootloop. At this moment i am only able to use twrp 2.7.1.0(only recovery that is working) and fastboot. I've tried wiping data through recovery and still nothing. Anyways my bootloader isunlocked. .
Also I've tried the forced update method to get it working again but for some reason I cant start it, just a bootloop.
When i try to install custom rom it just give me message "unable to mount data". Same message i get when i try to do factory reset or wipe data.
Appreciate the help guys.

The force update will not work since you replaced the stock recovery from Huawei with TWRP.
Follow these steps:
1. Go to Huawei's website and download the UPDATE.APP package.
2. Go to Huawei's website and download the Update Extractor tool.
3. Use the downloaded tool to extract the UPDATE.APP package. Then you should have a folder filled with .img files such as system.img, recovery.img etc.
4. Connect your device to your PC and enter fastboot on your Ascend P7 device
5. Open up Command Prompt or Terminal (cmd for Windows, terminal for Linux) and go to the directory where fastboot is installed
6. Check to see if your PC finds your device using the command: "fastboot devices". If successful, you should find your phone listed.
7. Flash this partition images using these commands:
"fastboot flash boot /path/to/your/images/boot.img"
"fastboot flash system /path/to/your/images/system.img"
"fastboot flash cache /path/to/your/images/cache.img"
"fastboot flash cust /path/to/your/images/cust.img"
"fastboot flash userdata /path/to/your/images/userdata.img"
5. Reboot your device
Now if successful, your phone should have EMUI installed on it. Hope this helps you.

Soft bricked phone? Can't install recovery and can't install a rom

Okay so I got my oneplus 3t today and I updated it to Nougat via the ota file all good so far. I then decided that I wanted to install a custom rom so I downloaded twrp supersu etc everything needed to root and install the rom. Here's where it went wrong in knowingly I downloaded the wrong twrp flashed it and it would just hang at the flash screen for twrp. Anyway after hours of trying to install a recovery I managed to get a stock one to semi work, now it turns out I don't know how I did it but my phone won't even boot it just turns on and goes straight to fastboot mode. I managed to get a stock recovery semi working but it won't let me install the stock rom from internal storage and I've tried updating through adb and it will hang at a random percentage for a good 20 mins and then just fail. Really need some help here it would be great, thanks
Hi,
If you can get into fastboot mode then the best recourse is through there. Hope you properly OEM unlocked your device.
First of all, you MUST have the latest adb/fastboot binaries and FOR SURE have the correct drivers.
Follow the links on this XDA article to download the latest adb and fastboot binaries: https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads
This is the link for the Windows binary: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
Extract all the contents of the zip file in a folder on your PC.
Then, also make sure to have THE CORRECT twrp, 3.0.2.0 or 3.0.3.0. This is the link but currently it is down: https://twrp.me/devices/oneplus3t.html
Download THE IMAGE, NOT FLASHABLE ZIP and put it in the same folder as the android platform tools above.
Finally, download the latest complete 3T firmware from OnePlus from this link: http://downloads.oneplus.net/devices/oneplus-3t/
I STRONGLY recommend not to use an update zip, even a full ROM update zip as that one might not include certain firmware images.
Put THE ZIP on the same folder as the others, DO NOT EXTRACT ANYTHING.
On your PC, open a command prompt in the folder where you extracted the android platform tools and run the following: fastboot boot twrp-3.0.3-0-oneplus3t.img (assuming you downloaded the 3.0.3 version of twrp).
Your phone will TEMPORARILY accept the twrp recovery as a boot image and boot from there. NOTHING IS BEING PERMANENTLY WRITTEN AT THIS TIME.
After that, enter TWRP's Wipe menu and wipe system, data and cache.
Finally, use TWRP's Advanced menu and enter adb sideload mode. Once there slide that slider to the right to enable adb mode and return to your PC and enter the following command in the command prompt:
adb sideload OnePlus3TOxygen_28_OTA_029_all_1612131737_17e7161d2b234949.zip (assuming you downloaded the 3.5.4 binary from OnePlus).
TWRP should properly flash the OnePlus ROM and hopefully, return you to proper function. You can then update back to Nougat.
Hope that helped!
Yeah that sorted it thanks a lot

Once I do "fastboot boot twrp" and get a success, then what?
Do I need to somehow reboot the phone into TWRP - because that didn't happen on its own.
If so, how do I do this?

My instructions while detailed are not step-by-step. I expect the person reading them to have their PC configured correctly and at least a vague idea of what they're doing.
So, assuming you put the correct TWRP image (my command uses the name of the image for TWRP 3.0.3.0, you MUST alter it to reflect the actual image's filename if it's not that) on the same folder as the fastboot binary then yeah, the command
fastboot boot twrp-3.0.3-0-oneplus3t.img
should have made your phone reboot and enter into the TWRP image that you had on your PC.
If it didn't then you did sth else wrong before that.
Either you didn't OEM unlock your phone when you still could or you didn't use the android platform tools that I linked or you don't have the correct ADB drivers installed on your PC.
Start from there.
Hope that helped!
Thanks for your help @KeyperOS - I know where I went wrong...
To save some time, when I tried to reboot into TWRP, I typed "fastboot boot " then I dragged and dropped the TWRP img file onto that line in the cmd window (rather than typing the filename manually) - when you do that, it appears to include the full path to the img - it was that that was causing the problem.
When I typed the TWRP filename manually, it worked.
The only thing that caught me out was after I'd installed the ROM (via adb sideload) I tried to reboot the device from TWRP recovery - this seemed to just hang. In the end I just powered off the phone using the power key, then powered it back up as per usual.
Checked that the phone booted to the first of the setup screens, then powered off/booted into fastboot mode, relocked the bootloader and it seems to be OK.
I'm now back on 3.5.4 again, which was what I was trying to do...
4.0.0/1 had felt a bit laggy, and I'd sensed some issues with wifi and BT, I can now run 3.5.4 and see how it compares - was I just imagining it?
Thanks again for the guide and your help - I really appreciated it
@PugRallye
Windows' command prompt has an autocomplete feature. If you want it to add the name of a file, type a couple letters and then present TAB, it's gonna complete the filename itself and if it's the wrong file you can keep tapping tab to cycle through all the options.
Really glad it worked out Btw [emoji4]
In my experience, 3.5.4 was great but 4.0 is a step up in both battery life, which IME is amazing and features, with it I almost didn't need root and certainly don't need xposed which was a first.

My nexus will not flash correctly

Hello guys, ive been generally lucky in the sense that i have had no issues...until now.
I have tried installing the most recent updates (7.0, and now 7.1.1) and i continue to get this error through cmd. It does not seem to want to flash anything, and i have gotten it to flash, root, and twrp, but it still acted funky. Today, trying to remedy the situation, i attempted to flash the new 7.1.1 update, and return to stock (to later return to power user) but it is still doing it.
It says Bootloader: has-slot (not found), and a couple other things. When i try to flash individual pieces, it does not retain it. when i try to flash the flashall.bat, it flashes but does not flash everything, it will say the stuff has transferred 0 and skips it as it looks like. I cannot get my bootloader off the october one, and i have looked everywhere i can to try to fix this.. please help, its driving me mad. I will be happy to provide any information needed.
Thanks Community! You rock!
Have you tried a different USB cable? A different computer? How about a different USB AND a different computer? I think this would be a good place to start.
Can i ask you why this would matter? My usb seems to work fine, and my computer had no issues before this... i can still perform different actions, and my phone is showing up as ADB and Fastboot.
If it's not pc or usb cable related you can try to flash latest factory image step by step via fastboot without your simcard
Well, you might want to post the complete output of your flashing attempt, but if the bootloader slot isn't found, that's usually a sign of a hardware problem. Hopefully I'm wrong, but until we see more from you, I simply don't have an answer for you.
Ive tried to fastboot everything individually, and it refuses to take. I tried the flashall, same thing. I used NRT and it partially worked, but has sorta the same error. I will be flashing again and providing screenshots right now. I was able to get into a rom, root, twrp but i still cannot update all of those core things (bootloader, radio, and such) Thank you guys for the help. Much needed.
Here is the attempt to just flash the bootloader, i have tried from a different location but this is directly in Platform-Tools of the SDK. As you can also see, it does register under fastboot...

I just tried what you suggest, and im not sure if it worked. It said everything wrote (on twrp) but it was very quickly done. I feel it did the same thing as CMD did.
You could try using the correct Fastboot command...
fastboot flash bootloader bootloader.img
The command is fastboot flash <partition> <image>
Your screenshot says only "fastboot flash image" but doesn't state the partition you're trying to load, hence "unknown partition".
And since we're on the subject, perhaps a repetition of the procedure I used to use before the full OTA days might be useful to you and other people.
Preparation.
- Take a TWRP backup and save it on your PC.
- Download factory image (https://developers.google.com/android/nexus/images#shamu) and unzip all files, including the zip within the zip. Rename the *.img files to the names below. Copy all of them to the same folder as your ADB/fastboot executables.
- Download the relevant TWRP and rename to twrp.img - also put in ADB/fastboot folder.
- Copy SuperSU to device (if root wanted).
- Set USB debugging in Developer options & attach to your PC.
- Open a CMD window, navigate to your ADB folder, and check connectivity with "adb devices". If it's ok, copy & paste each command below into the CMD window and run them - the only lengthy one is the system.img.
1. adb reboot bootloader
2. fastboot flash bootloader bootloader.img
3. fastboot reboot-bootloader
4. fastboot flash radio radio.img

Can you give a bit more detail? So the phone is crashing, but is it now on the version that you wanted to have (7.0, 7.1.1)? There is rarely such a thing as "too much information".

Ok, so what happens is that it says i am on 7.1.1 with i guess the related info, but it does not load in properly as you can see with the screenshots. I start up the initial setup, and i can get through most of it fine, but some areas *permissions* are all blotchy. like i can toggle them on to submit data but i cant see what it is exactly im agreeing to. Then i start the phone, Google App automatically crashes, along side system ui. When i updated them, it seemed to fix the problem. But the issue is, i am not receiving phone calls and texts until possibly days later, and when i send texts it says "sending" and proceeds to spam the hell outta whoever its going to (sends literally 30+ texts). When i call someone, my phones Do Not Disturb mode gets enabled, and then nicely cuts out my audio. I can turn this feature off when im in the call, but sometimes it will then glitch the phone app, and i cannot essentially "hangup". My phone also now dies at 9%, where it had not previously (when i was on other rom / older stock) This all started after i updated to the october patch, and i noticed in december that i didnt have the december patch / update. I went to install it, and the same exact thing occurred. Ive attempted a rescue ota, and a sideload ota, and now this stuff as well, but i fear the worst for my phone. Let me know if i need to add anything else
Strephon may be right in suggesting a hardware fault, but equally it may just be that your phone is now somehow corrupted. My only suggestion is that you nuke it - factory reset, TWRP, wipe everything again in TWRP, and then try installing from fresh using the 7.1.1 full (not OTA) image and the instructions I posted earlier. If it still doesn't work I'm out of ideas, but there are people with far greater experience here than I have, so don't give up. It's too nice a device to just write off.

That's a new feature of 7.1.1. So you won't have to listen to notifications while on the phone. It's disabled as soon as the phone call is over.
