So I recently grabbed me a Grouper recently to *cough* remember my first Android powerhouse (before I met the Optimus G) and decided to tinker with it as usual. I've owned 6 (now 7) different Groupers in this lifetime and have great experience with it, how to get those pesky drivers working, etc. This is my first 32GB model ever. Anyways, I unlocked the BL, rooted and flashed TWRP (thanks to WugFresh's toolkit) and decided to play with the newer roms (last time I owned one, KitKat was a rumor) and kernel combos. Anyways, I decided I prefer its stock performance and battery, and that maybe I'd use Xposed to tweak apperance instead. My mistake was, I should have flashed a flashable stock rom. But NOOOOO...I decided to flash it back to stock with the fastboot method (which we have various threads on, and toolkits including WugFresh's). Trying the manual method, I followed the following guide using a 4.4 image zip file:
http://forum.xda-developers.com/showthread.php?t=1907796
Claims that the sysem.img doesnt exist when it gets to that part. I extracted the entire file and it DOES exist. Anyways, I tried WugFresh's tk and sort of gives me the same ending (after literally almost an hour of waiting TWICE due to my old PC).
THERE WAS A GUIDE I SAW SOMEWHERE while Googling "how to" get back to stock on Google which actually point ou how to MANUALLY flash each .img yourself one by one via fastboot, which I really intended on doing instead of the above methods (DIY anyone?) but I can't find that guide and I'm not even sure if the post was here on XDA or Android Central. I should have done all Google search on the PC instead but ATM the tablet seemed more convenient for a search.
Anybody know the guide I am mentioning or know what I am talking about? I am assuming that method will solve my dilemma, and I like doing these things manually at times anyways....
EDIT: To my disappointment, found the post, but no good:
http://www.androidbeat.com/2013/11/flash-factory-image-nexus-device/
Apperantly everything flahes fine until it gets to the system.img part...adb/fastboot just freezes there and wont budge at all. Since I noticed that it did flash things, I've decided to flash TWRP and just flash a rom from my flash drive (thanks to a USB OTG) but I would still like to actually FIX the thing properly and return it 100% stock. Any ideas?

I'm not sure what you mean by stock. Are you trying to flash a "Stock" rom from the community or the stock images provided by google?
If you are using nakasi-ktu84p image, the flash script contains:
Code:
fastboot oem unlock
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
sleep 10
fastboot -w update image-nakasi-ktu84p.zip
You can see here the exact process of getting back to stock.
The boot, cache, recovery, system, and userdata are erased.
Then an attempt to flash the bootloader. This will fail on nakasi-ktu84p and several images back.
Google has been negligent in addressing this issue.
I was able to find success with bootloader-grouper-4.23.img which I extracted from nakasi-krt16s.
You could save time and bandwidth from acquiring it here.
This bootloader also failed to flash for me!
If you have flashed a custom bootloader in the past, you may need to go all the way back to JDQ39 bootloader-grouper-4.18.img.
fastboot flash that, and then you will be able to flash 4.23 from krt16s.
Once you have passed this small ordeal you should be able to install the latest ROM.
In summary, you should be able to do the following from a system that has the fastboot binary:
Code:
EXTRACT nakasi-ktu84p-factory-76acdbe9.tgz
OVERWRITE bootloader-grouper-4.23.img with one acquired from krt16s
Code:
nakasi-ktu84p bootloader-grouper-4.23.img
MD5 = 5bdb2e87370cdb1a7ea14bb0c3e21390
krt16s bootloader-grouper-4.23.img
MD5 = df53028033c9eccf4fe5ba7bc198ce24
Code:
run flash-all.sh or flash-all.bat
PS.
I have been lured by the idea of stock stability, performance, and battery life. Something about Xposed seems dirty to me.
Battery life and Performance have always been better on a custom ROM / Kernel in my experience.
Stability can be rock solid when you've got a good system.
My favourite solution is to have the stock image installed and stripped down for size. This always you to boot in and update your apps from playstore.
I then install a custom ROM alongside via multiRom. This rom also has extras stripped out and no gapps installed.
From Rom 1 you can copy your apks into Rom 2 as needed.
I tend to avoid any apps that would be incompatible with this method!

Your on the right track that's exactly what I was looking for, but to me it doesn't work on the system.img flashing part, it stays stuck there forever without a hint of movement at all. I left it flashing from 4am to 7am with no progress. I though it was working as the Windows Task Manager was showing fast boot constantly changing in CPU usage as it does when its at work. But sadly, it gets stuck there for good. Then closing fast boot won't work, I have to shut down the PC in order for it to leave

I'm not familiar with the tools you are using. Have you used the commands directly from the command line, and what is the output?

WugFresh is a toolkit made to root, unlock boot loader, relock, restore to stock, etc. And yeah I used the fastboot erase and fastboot flash commands via ADB/fast boot and as I said, everything goes well except the part where its time to flash the system.img, it just hangs there doing nothing. Tried and left it for several hours and still nothing
Try a different USB port on you computer or a different USB cable... or both.

Hi, Crossvxm...
This seems to be a relatively common problem, and I always seem to have it myself when fastboot flashing factory stock.
I've no idea why, but the fastboot connection seems to 'time-out' when fastboot flashing 'system.img'.
Now normally, and just prior to running any fastboot flash commands, you should run this command...
Code:
fastboot devices
This command doesn't actually do anything; it's essentially just diagnostic and is used to confirm you have a viable fastboot connection prior to flashing anything. If do you have a fastboot connection, you should see something like this (with the N7 booted into the bootloader)...
Code:
015d2d42xxxxxxxx fastboot
This is the Nexus 7's unique serial number followed by the word 'fastboot'. If you don't see this, then you likely have a driver problem...
...BUT HOWEVER, I KNOW I DON'T HAVE A DRIVER PROBLEM.. so when having problems with 'sending system', and upon opening a second command prompt window on my Windows laptop, and typing fastboot devices again, the Nexus 7's serial number now no longer appears... and this is AFTER the bootloader and boot img's have been sent and written successfully.
At this point, I can only conclude, and that for unknown reasons, my fastboot connection has 'died'... and 'sending system' is now permanently 'stuck'.
And the fastboot flash attempt has failed.
-----------------------------------------------------
The solution for me, was to change to a different USB port on my laptop. Another possibility might be to try a different USB cable... I haven't tried this... just a change of USB port on my laptop was sufficient, and the problem with flashing system.img was resolved.
Either way, reboot the N7's bootloader using a differerent USB port on your computer or a different USB cable... and attempt the flash again.
One final point... 'sending system' does take longer than the other .img's, probably due to it's size... but it really should take no longer than around 5 minutes... 10 minutes maximum.
Hope this helps... and good luck.
Rgrds,
Ged.
Hello,
Tried to update to lollipop like the rest of the world..well, i should have waited
At first i just ran the flash-all.bat (edited so it didn't include erase userdata and the -w option)
fastboot threw all sorts of errors, too many links, invalid argument
then i tried to run manually the commands, same thing. Not all of them "worked" at once.
Unfortunately I don't have a log.
So now i have a N7 that won't boot past the Google screen
I can get to bootloader but it shows on device manager as Unknown USB device, Device Descriptor Request Failed, so fastboot doesnt help.
I can also get to stock recovery and use adb just fine.
Is there anyway to fix this? sideloading anything?
Tired of waiting for the OTA? Can't use it because you're rooted? Don't want to wipe your entire phone? No problem! Here's how you can upgrade with Google's Nexus factory images without wiping your apps or sdcard.
NOTE: You must have your bootloader unlocked. If you've never unlocked your bootloader, I don't think there's any way to do this without wiping your data.
STEP 1: Install fastboot
Fastboot is Google's utility for flashing factory images. You can also use it to flash custom recoveries like TWRP and CWM. The standard way to get is is through Google's Android SDK, but that's a bit heavy-duty, so you can also download just the most important tools (fastboot and adb) separately, packaged by users. Here are some links:
Official Google Android SDK (cross-platform): http://developer.android.com/sdk/index.html#Other[1]
Unofficial for Windows: http://developer.android.com/sdk/index.html#Other[2]
Unofficial Mac/Linux: http://code.google.com/p/adb-fastboot-install/[3]
Windows users might also need to install drivers: http://developer.android.com/sdk/win-usb.html[4] (can any Windows users confirm whether it's necessary?)
STEP 2: Prepare factory image
Download the latest Nexus 6 factory image at https://developers.google.com/android/nexus/images#shamu[5]
Unzip it and open the resulting folder
Unzip the "image-shamu-*.zip" file in there
You should now be looking at something like this: http://i.imgur.com/mzrfwrP.png [6]
STEP 3: Flash! (Ah-ahhhhh! [7] )
Connect your phone to your computer via USB, and enter the bootloader. You can enter the bootloader by holding down the power and volume-down buttons to boot. Once you see the bootloader, you can release the buttons.
Open a terminal/command prompt. The syntax might be slightly different on Windows than on Mac or Linux, but basically the same. Anything you see in <> you need to replace, e.g. with the actual path to your factory image folder. The rest you should be able to copy and paste. (Tip: you can easily enter a folder path into your terminal/command prompt by simply dragging the folder onto your terminal window. This works on Mac, Windows, and the vast majority of Linux GUIs.) Enter these commands:
cd </path/to/shamu-lmy47d>
fastboot flash bootloader bootloader-shamu-moto-apq8084-71.08.img
Reboot the bootloader.
fastboot flash radio radio-shamu-d4.0-9625-02.95.img
cd <image-shamu-lmy47d>
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash system system.img
If you DO NOT use a custom recovery (like TWRP or CWM), then also: fastboot flash recovery recovery.img
Don't worry if you see messages like "target reported max download size of 1073741824 bytes". Just wait and let it finish.
Reboot your phone and enjoy. It's normal for the first boot to take a while. Going from Kitkat to Lollipop took about 20 minutes. Going from 5.0 to 5.0.1 took 5-10, I think. YMMV.
A WORD OF WARNING: If you're moving between ROMs, you generally should do a complete reset, including wiping data. Many users have reported problems going from KitKat to Lollipop without wiping data and recommend a factory reset anyway. If you're okay with wiping everything, you can simply use Google's included flash-all scripts, or flash the userdata.img file yourself. Personally, I'm not going to bother wiping adta for an incremental update like 5.0.1->5.1. As always, be sure to back up your data!

Shouldn't you also fastboot reboot bootloader after radio flash?
This is the scenic route.
I tried to update using wugz, without unlocking the bootloader. failed. Oh well, I'll wait to receive ota
Unless this method doesnt require unlocking?
If you have an OTA zip file, this is different than using a System Img?
I do not think you need to lose data or unlock your bootloader?
Found a link for the OTA zip file.
If I remember right you can copy the zip to you phone with a USB cable.
Go into the bootloader, Volume Down and Power.
Select the zip.
I did not think you needed a terminal and all the commands if you had the OTA zip on your phones SD card.
Am I wrong does something like this not work?
or
I can just wait.....
This worked great.
I was unbranded with VZ sim, unlocked, rooted with TWRP recovery. Didn't want to lose all that nor my apps or data. This method upgrades to 5.1 without any loss.
When I was done with the flashing, I rebooted to TWRP recovery (not system) in order to wipe dalvik and cache (just to be certain). I wiped and then rebooted to system. TWRP noticed I didn't have SuperSU installed so it installed it for me. Meaning, once I got my system rebooted, I still had root too.
All in all, this process worked great for me. Thanks.
I run the first two commands
fastboot flash bootloader bootloader-shamu-moto-apq8084-71.08.img
fastboot reboot-bootloader
they worked, then i moved to the radio
fastboot flash radio radio-shamu-d4.0-9625-02.95.img
but it failed.
Any idea?

This is the message after the radio flash command:

Why the failed message?
I'm decrypted. Will this re encrypt my Nexus or do I have to flash a non enforce img?
Thank you, this really helped.
Since my bootloader was locked i had to unlock it as well.
Had a bit of a scare with the whole erasing screen staying on for too long.
Went back and redid the process, and went downstairs for 5 minutes, came back and phone was booted.
Anyway, thank you again

I don't suggest that anyone read and follow someone else's instructions when doing something like this. Not because the instructions are wrong or anything, but because blindly following instructions doesn't involve *understanding* anything.
So rather than reading and following instructions, read and UNDERSTAND the process of installing factory images as delivered with the factory images (flash-all.sh). If you UNDERSTAND the process and what everything does, then (a) you *already know* what needs to be adjusted to do what you want, and (b) if something starts going wrong in the middle of it, you will understand why, and what to do to correct it.

First, thanks for the write up, I do greatly appreciate it. Second, thanks for the tip on dragging file locations into the command prompt. Very helpful.
Now my question. When I did this I tried using exactly the steps above and had no luck whatsoever. I'd cd to the location of the img files as noted and it would say fastboot is unrecognized as an internal or external command. I moved the file into the fastboot location and got the same issue. I finally ran the fastboot from the adb folder location and just referenced the full file path for each img file (using the drag and drop method) and everything went swimmingly. My question is just about using fastboot. Should it have worked when I used cd to go to the img file location? Is there something I need to do to make it work as you described?
Thanks!

Install this:
http://forum.xda-developers.com/showthread.php?t=2588979
Now ADB and fastboot are installed system wide. Put your files anywhere, I use the desktop. Hold shift and right click on wherever your files are and select "open command prompt here" and flash away. Simplified, no more dragging and dropping.
Will try with the new update (5.1.1 (LMY48M)) to ensure it works. Thanks!

Have been flashing this zip in twrp after the fastboot stage without an issue for the last few updates - http://forum.xda-developers.com/nexus-6/development/mod-disable-force-encryption-rom-kernel-t3000788
Flashed LMY48M with fastboot method and it works great.
My phone is encrypted.
Hi,
I did search, but I didn't find any solution to the issue. I got the Nexus 6P 64 GB.
I unlocked my bootloader using the 6p Multitool. Thereafter I used my normal method of fastboot (Minimal ADB) to flash the boot.img from this thread http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344.
After that I flashed TWRP. Basically I followed the instructions here: http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928.
But my phone is not booting up.
It gives me this error:
Your device software cannot be checked for corruption. Please lock the bootloader."
But I tried that and it doesn't work. I tried from fastboot restoring to factory, but get the same message.
Please help me!
Did you check the enable oem unlocking in developer settings?
Sent from my Nexus 6P using Tapatalk
Yes. As I said, I achieved the unlock. Now I just can't get back into my phone or recovery or anything other than fastboot (where it says unlock)
isn't "Your device software cannot be checked for corruption. Please lock the bootloader." the new msg on boot when you are unlocked, and you have to wait ~10 secs before it startup ?
After that, I'm stuck on the Google screen. It just goes on and on. Left it for over 20 minutes at one point and it didn't get past it.
Edit: The multicolored animated google screen. The animation just keeps going and going.
Del.
Your issue might be due to the encryption of the phone. Take a look at this thread: http://forum.xda-developers.com/nex...recovery-twrp-2-8-7-0-touch-recovery-t3234976
From this thread:
NOTE: Decrypting data is not supported yet. The Nexus 6P will normally attempt to encrypt the device automatically on first boot. To use TWRP as you normally would, you will have to format data and install a slightly modified boot image with forceencrypt disabled. My Nexus 6P should arrive tomorrow and I will start working on decrypt once I get my hands on it.
Team Win Recovery Project 2.x, or twrp2 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Read through that thread. Part of the issue is that I don't know which variant (MDA89D & MDB08K) I have, or how to find that out seeing as I can't boot into the phone.
If I have the variant I may be able to fix this through the unified toolkit (though I'm not sure of that)
Did you ever fix this?
Try flashing the factory image and starting from scratch. You must have messed up somewhere. Re-download the boot.img from Chainfire's thread, maybe that was corrupt or something.
1. Download the MDB08K factory image (it's not a variant, it's a Marshmallow update) and unzip it.
2. Download the MDB08K boot.zip from Chainfire's modified boot.img thread
3. Download latest SuperSU beta zip
Wipe phone in TWRP, to include format data.
In bootloader, fastboot flash MDB08K
fastboot flash modified boot.img (from zip)
In TWRP, ADB sideload SuperSU
Reboot and it should perform normally.

Thank you for your reply, but I can't get into TWRP either!! Any way for me to restore to factory or do the repairs from in flashboot without the restore?
I ran into the same issue last night trying to install TWRP. I'm still not sure how to get around it but I did get my phone back. you should be able to get to the bootloader (hold the power button until phone turns off, then hold vol up+vol down+power) once there use ADB fastboot to go back to stock.
this link will walk you through what you need. follow step 7.
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
here it is as well:
How To Flash The Factory Images (And Return To Stock)
Prerequisites: unlocked bootloader (section 1).
Download the appropriate factory images for your model here.
Unzip the angler-xxxxxx-factory-xxxxxxxx (x's replace variables) into a directory on your PC (for this guide we'll use C:\angler\).
Once unzipped you should have a folder named angler-xxxxxx (x's replace variables). Open it and move the following files to a new directory named C:\angler\images\:
bootloader-angler-angler-01.31.img
radio-angler-angler-01.29.img
(Please note that radio and bootloader naming changes from build to build so the filenames and below commands will change with them)
Within C:\angler\angler-xxxxxx\ you'll see another zip archive named image-angler-xxxxxx, unzip the contents of that zip into the C:\angler\images\ folder we created before. Now within C:\angler\images\ you should have the following files:
android-info.txt
boot.img
bootloader-angler-angler-01.31.img
cache.img
radio-angler-angler-01.29.img
recovery.img
system.img
userdata.img
vendor.img
Boot into the bootloader and connect your phone to your PC via usb cable.
Open a command prompt from within your fastboot folder (navigate to where you have fastboot.exe located on your PC, shift + right click anywhere within that folder, select open command prompt here), enter these commands to flash:
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-01.31.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-m8994f-2.6.28.0.65.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash userdata C:\angler\images\userdata.img
fastboot flash vendor C:\angler\images\vendor.img
Thank you. I was eventually able to do tysonwald's suggestion. First I didn't know what my version was, so I couldn't.
At some point I was able to get into the phone with constant gapp errors, check it.
Now my phone is unlocked and rooted. But when I go to settings to security (and when I tried to set up my fingerprint) settings crashes. Any ideas?
There was still some issue. I wiped the phone with the above method again, did NOT set up twrp/root, and everything works. It was something about the custom boot image I guess. Any advice if I want to try to set it up again?
Problem solved. Needed to update to newer image before doing everything. Issue resolve from Heisenberg's thread. Thank you all!
I had the same damn issue last night. Thise bootleg instructions had me flashing build k boot.img on build D. Maybe i wasnt paying attention lol!
I have a very similar problem, I flashed the k boot img. and now I'm stuck in an endless bootloop any idea?

I had a similar issue just now where my phone got stuck at the TWRP logo. Selecting the reboot option in download mode refused to remove it. I had to follow step 10 to get my phone back to stock. I'm afraid to try this again now
Is there anyway to know which version do i need to download? i bought the phone already bricked and i am trying to bring it back to life
Hi,
Today I wanted change my recovery. I had the Lineage OS recovery, but i was trying to install the twrp recovery.
So, the guide of twrp says that you should boot the twrp via fastboot boot twrp.img and install via the booted twrp. But I mistaken the command and I wrote fastboot flash boot twrp.img, I tried to reboot and the device booted himself in fastboot with the enter reason "error boot prepare" and I can't boot into the system or recovery.
I tried to flash the official image downloaded from the Google Developers website, but when i run ./flash-all.sh, console get stuck. I waited for about 15 minutes but nothing. I tried even the official Android Flash Tool but after 10 seconds it says "Your device stopped responding. You may have to select restart in the bootloader menu in order for it to be recognised again."
Does anyone know how to help me? Thanks in advance.

Yes, I wrote in the post, I tried both the command line tool and the chrome version. Btw i'm on linux
Okay so, I fixed.
For anyone who will have this problem you just need to flash official Android 9 and next Android 10. Only with Android 10 you can use fastboot flash boot recovery.img (you can't use twrp in android 10 with the Pixel 3a)

Does this work if adb not working? I only have fastboot.

It depends if your pc were authorized, if it was, you can use fastboot to flash the stock version of Android 9, just running the flash-all(.bat) script.

I'm not certain I understand what you mean by PC authorized? I'm using a Windows 10 tablet. When the phone is attached to the computer it sees it as a device that can be disconnected through USB.

I just had an encounter with this. I was rooting my device (Pixel 3A) and messed up my partitions through accidentally attempting a downgrade which broke all my ****. I was unable to easily reset this device to factory, so it took me several days to figure out and root. I'm getting better though as a hacker, because a year ago this would have taken me a month.
I was able to enter recovery mode (lying down Android, NO COMMAND). From this recovery mode, adb devices -l recognized my device, although I was unable to get a shell.
At first, ADB was telling me the device was authorized, but I messed with a bunch of other stuff (tried to flash a bunch of different partitions and monkey around in general trying to install Magisk) and then ADB started telling me it wasn't authorized when I used devices -l.
Once it said unauthorized, I was unable to issue the device any commands with ADB, so I just used hardware keys to get into recovery mode. From there, I selected OTA update, and it got into sideload mode. At that point, I used adb sideload with the OTA package that I downloaded here https://developers.google.com/android/ota
^^^ That operation did successfully restore my device to factory
This following guide here describes the details of how to use hard keys to enter recovery on this phone (don't download anything from there tho, and make sure your adblock is on)
How to Hard Reset your new Google Pixel 3a [Tutorial]
In this article, you will learn how to start your Google Pixel 3a up into the Recovery Mode and perform the Hard Reset to make it work perfectly again.

I just wanted to say, I've been wrestling this hardbrick for a couple of days with my Pixel 3a.
I've finally overcome it by sideloading the most recent OTA update after using a hard key combo to get into recovery mode. The hard key combo is hold Power Button, tap Volume Up, then release both. Then, all you need is to use the command:
adb sideload <OTA.zip>
^^^OTA wasn't the actual filename though, you can download OTA packages for Pixel 3A here: https://developers.google.com/android/ota
the OTA binaries are NOT the same as the factory images, which is here
Factory Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
Sideloading the OTA package brought my phone back from only having fastboot and recovery mode, even when flash-all.sh from the official downloaded firmware failed. Now I know how to undo damage that I cause by rooting this thing. Since I sideloaded newest firmware, it was also like applying an update. I easily got root after that, and I've logged the process. I'll make it into a guide soon
I'll just note that if you accidentally flashed the TWRP boot image instead of simply booting into it, I believe all you have to do is flash the stock boot.img to fix the problem. Obviously you can sideload the entire rom image, but that shouldn't be necessary.
Using the Windows computer (or whatever computer you are sending ADB commands from), download the full stock image directly from Google. Unzip it and then upzip the folder inside. You should find the boot.img file inside that folder. Take that file and then flash it to the phone using the normal ADB command: fastboot flash boot boot.img
While I haven't tried this myself recently, it should work in theory. The command "fastboot flash boot twrp.img" flashes the boot partition with a non-working twrp image, so replacing the faulty image with the stock boot.img should fix the problem.
If I did the same I would first attempt to manually put device in bootloader/aka fastboot mode then fastboot flash the stock boot.img , sudo fastboot flash boot boot.img --slot all
I only read the op (first post here);but I betcha that would have worked. Then sudo ./flash-all.sh and let it do it's thing.
