Your device is corrupt. It can't be trusted and may not work properly. help!

Long story short, hopped over to android following years and years of using IOS.
Bought a nexus 6p, learnt about root, gained root access to the 6p, and began installed root apps.
This morning, i installed Gsam battery monitor root companion, found out it broke the normal Gsam battery monitor app, tried to uninstall the gsam root companion several times. Everytime i uninstalled it and rebooted, it would just reappear on the phone and wouldn't actually uninstall properly at all.
On the third go, it rebooted into the red triangle " Your device is corrupt. It can't be trusted and may not work properly." and is stuck on the google logo.
Accessed recovery and tried to restore the nandroid backup, no luck, still boots up to red triangle and is stuck on google logo.
Accessed recovery and tried to restore to factory default, no luck, still boots up to red triangle and is stuck on google logo.
How do i fix my phone now? Any help would be greatly appreciated.

red triangle with the android mascot logo?
if so, put it into fastboot and reinstall recovery and see if that worked

Its just a red triangle with an exclamation mark inside.
I can't post an image because i am a new member and need at least 10 posts.

https://support.google.com/nexus/answer/6185381?hl=en - It says it should dismiss by itself.

The red logo does disappear and the device transitions to the black and white google boot logo.
It is here where the device becomes hung, i assume it is because the boot.img or boot files have been damaged, but i'm just guessing. What i am confused about is if the boot files are damaged, the nandroid restore should fix this problem (shouldn't it?), but it doesn't.

After a root went bad I had the same thing happen. I just used SkipSoft ToolKit and restored back to a stock image (MDB08L).
The corruption message disappeared.

Take a look at this guide By Heisenberg as it will help with some details.
The few times I flashed/reset the phone, I accidentally muddled up some steps. Specifically the flashing the boot and bootloader images.
Code:
[U]fastboot flash bootloader X:/bootloader.img[/U]
fastboot reboot bootloader
fastboot flash radio X:/radio.img
fastboot reboot bootloader
[U]fastboot flash boot X:/boot.img[/U]
fastboot erase cache
fastboot flash cache X:/cache.img
fastboot flash recovery X:/recovery.img
fastboot flash system X:/system.img
fastboot flash vendor X:/vendor.img
I would accidentally flash the bootloader.img image over the boot.img and cause the error, specifically the one you mentioned. I had to go through the flashing process VERY carefully again, and when flashing .imgs for root acess over to the stock ones.
I know is sounds trivial and I'm not saying you don't understand it, but give it a try and see if this resolves the issue. double check your lines and triple check your images (make sure there are NO spaces in the bootloader/boot img file directories. or_replace_spaces_with_underscores). I don't know how many times I have screwed up and it was because of a dash in the wrong spot or space in the .img directory. Let us know how you go.

Awesome!
Thank you very much everyone. I will try once i get home from work.

Just go to my guide and follow the instructions in section 9. You'll need to look at the prerequisites section at the beginning of the OP first so you can install the latest version of adb/fastboot via the SDK.

Im sorry but I'm completely lost. I have downloaded the factory images of my build, I have extracted the files but there isn't any bootloader.img and radio.img. When I click the extracted file it asks me if I want to download a windows application to open it.

Basically i followed step 9 of Heisenberg's guide.
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.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 vendor C:\angler\images\vendor.img
So i flashed all of the above minus the user data and re-locking the bootloader.
Let me know if you need any more info.

Thanks bud. I'm lost still. I have all the files needed in a folder I called " images" on my desktop. Do I have to write these commands you posted word for word? I mean I know I have to replace with my file name but for example I have the MDB08L so do I do : fastboot flash bootloader C:\angler\images\bootloader-angler-angler-02.01.img ( in my case) even though the folder is on my desktop?
Edit: I tried and it gave me an error saying it cant load it. So frustrating

You got an error because you're pointing fastboot to a location where the file doesn't exist. If you had followed my guide and placed the files in C:\angler\images\ then the command would be correct, but you've placed the files in a different location, therefore you need to type the commands so that they include the path to where the files are actually located on your PC.
There's an easy way to do it, type the first portion of the command, for example "fastboot flash bootloader " (make sure there's a space after the last character), then you can grab the appropriate file with your mouse and drag/drop it into the command terminal window and the file path will be completed automatically for you, then just hit enter to execute the command.

One last question, whats the best method to root MDB08L? I want that chroma rom

No OS Installed While Flashing Android N OTA In TWRP

So yeah I accidentally wiped my partitions as if I were installing a rom. Am I screwed until I get to a pc?
P.s. Out of all days to delete my backup rom file ?

Just set it to boot loader mode and flash stock images...I'm sure there's a tutorial on how to do it..I have the program installed on my computer ready for any time I brick my phone lol but I don't remember the name of the program right now
Edit: heres the link to the method I use http://forum.xda-developers.com/showthread.php?t=3258493

I'm assuming the OP doesn't have a PC due to the last statement he made. I would say yes, nothing you can do until you can get to a PC and flash stock images via Fastboot. Unless you have a ROM zip on your phone that is....which I'm assuming you don't.

You're kinda stuck, you need a PC to flash the factory images. TWRP can't flash OTA's anyway, so don't try that again either. I'd strongly recommend not using a toolkit to flash the factory images too. I have a detailed guide here:
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928

Hey guys, having a similar issue than zachbuilds. While rooting my nexus 6p on NRD9M, I formatted to system partition for root to stick and noticed twrp stated I have no OS installed. At that point I was going to flash stock image file when my nexus reverted from default MTP to charge only and now my Mac is unable to recognize my device Ann's now adb is non operable. I tried to fastboot adb commands but that isn't working either. Any one have any suggestions. I'm on stock with twrp custom recovery, no other changes were made to my device. Also, recovery and bootloader are accessible. Thanks for any help given.

Can fastboot see your device when you're in bootloader?

Yes fastboot is able to reconize my device.

Best just to flash back to factory images. Be cautious if you've flashed the Android N OTA though, there are some strange things going on with people trying to flash back to M. Read up before you flash.

I've actually tried flashing stock images but every time I tried to run fastboot command I get these errors, "command not found" and I believe the other erro is "file path not found". There's another error that I can't remember off the top of my head what it. When I get home I'll try to run the commands again and see what errors I get

What bootloader version are you on currently? Although updated bootloader is recommend, you should be able to skip this step without any issues.

Please post the entire command you are using, as written in your terminal prompt. "No command" sounds like an unrecognized command is being issued. We must use ./ in addition to the fastboot or adb command in order for OSX to execute the action. If following Heisenberg's guide for fastboot, the lone change you need to make for OSX is:
./fastboot devices
./fastboot flash
./fastboot reboot
./ADB devices
Try this out and post your results.

Just throwing this out there, it is possible to flash an OTA in TWRP. You still need a PC but its do-able.... I flashed Android N Final to my 6P yesterday by copying the OTA zip (uploaded thanks to another member) to SD, Wiped device as I normally would with any other ROM (left SD intact obviously), Flashed OTA ZIP, rebooted straight to bootloader after flash, fastboot erase boot, fastboot erase recovery, fastboot flashed DECRYPTED BOOT.img (which can be found easily), fastboot flashed TWRP 3.0.2-1 (version just released for N), fastboot format userdata, fastboot format cache, reboot from bootloader directly into TWRP, flashed superSU 2.74, reboot system..... Phone runs beautifully. Not a single issue. Entire process from start to finish was less than 10 minutes.
Its not the most practical route but it does indeed work. OTA just hes to contain the entire Image. I should also mention that this was a jump from a Marshmallow based rom (RR) so you don't have to be on an N preview in order to do this....

May Factory Image now available MXC89F

For those in custom recovery land just flash the system and vendor img to upgrade
now in May flavor!

Well it should be great IF our TWRP could mount vendor / system correctly
Only boot / recovery partitions are selectable for .img files :/
Edit: I´ve flashed the files via ADB - all went fine

The value of this posting would increase exponentially if you took it upon yourself to share what and how you flashed the files with ADB.

Sorry for my ignorance
Extract the ryu-m5c14j-factory-b714e9bd.tgz with i.e. 7-zip. In image-ryu-m5c14j.zip you find both files system.img and vendor.img.
So... I´ll hope you have some practices using ADB / fastboot. Put both files in your ADB / fastboot folder. Activate USB debugging on your device and restart it in fastboot mode. Connect your device with your USB-C cable.
Go into your ADB / fastboot folder and press shift / rightclick your mouse at twice and open the command prompt.
Bye typing "fastboot devices" or "adb devices" you can check if your device is correctly connect with your PC.
If you´re connected type "fastboot flash system system.img" and wait for end of process. After that type "fastboot flash vendor vendor.img". Now you can reboot your device by typing "fastboot reboot"
Those are my oldschool steps without losing data or settings.

No chance of losing root either, is that correct?

Well I assume that you have TWRP? Reboot into recovery and flash supersu again. That´s all If not you can sideload it via ADB.
In my case I have reflash supersu & xposed framework in TWRP

Than you´re device is rooted again. With this method you lose no data or wipe anything (ok.... some cache *g)

Hello there,
so I am in a little conundrum here.
I flashed the system.img and vendor.img following the instructions, but the pixel was just stuck at the plain Google logo.
After giving it something like 30 minutes, I had to power it off.
I am using TWRP and dragon-boot-encryptable-rooted-MXB48T-02102016-1.img stock kernel.
Another boot went without success.
my next thought was to downgrade to MXC14G but trying to do so resulted in:
Code:
c:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash system system.img
target reported max download size of 268435456 bytes
erasing 'system'...
FAILED (remote: unsupported command)
finished. total time: 0.004s
So far TWRP is working and I can operate within it.
Any ideas what went wrong? Should I format system and vendor in TWRP? I don't think this is a good idea... (Last time I tried to do so in this experimental version of TWRP I had to fight a long fight to revive it, because the formatting tool in TWRP was stuck. But that's another story.) Any way to flash the system.img and vendor.img from within TWRP?
Any help would be much appreciated, m8s.

After playing around in TWRP and using the fix fastboot option I am finally able to flash system and vendor in fastboot.
I don't know if the fix fastboot was really the solution, maybe just some sort of placebo, but nevertheless I am able to flash. Problem with the bootloop remains:
Google logo, reboot recovery.
My data partition is alright. What do I need to flash to get it going?
Going in circles here...

Yes, it is verified. I am using all kinds of ways to restore the pixel.

Pleas try to reinstall right drivers, change the cable / USB ports. I think your main problem is your system configuration. Good luck

m8... so glad I wasn't too tired to listen to your tip. Awesome! Redid all the steps on my freshly installed laptop, and voila!
Seems either my main PCs USB-connection is flunky or I am damned to reinstall my Windows soon. Scary...
I used the following software to revive the Pixel:
official Google USB Drivers
You have to unzip the file and right-click and install it
then you have to go to your device manager in windows and after connecting the tablet with the PC and getting into fastboot
Find the Android device on the top, select to change driver and go straight to manual selection of the driver, select android and bootloader driver
unpack the official Factory Image with 7Zip until you get to the folder with the flash-all.bat
get the minimal adb fastboot and unpack it in the same folder as the flash-all file
wait until you see the sweet booting animation
I think I didn't forget anything important. My Pixel is alive and ready for prime time.

Following redukt's instructions, I got the same error that rambobo saw. I rebooted into TWRP and executed the "Fix fastboot" option, then rebooted back to the bootloader. System & Vendor image flashing via ADB worked fine
I am now running M5C14J without loss of data, root, or recovery.
The OTA update reminder disappeared on it's own after 5-10 minutes.
Thanks yall!

You didn't have to apply root again via ADB or TWRP?

Correct
But judging from others' experiences here, YMMV. I tried the latest FlashFire build too, but that got me nowhere.

OP2 stuck in bootloop on upgrading 3.0.2 .. even after trying tons of things

First of all i want to say thankyou to the xda community who help people like us and build rooting and other flashing softwares.
So, this is probably my first post on xda, first for sure when i'm stuck and asking for help
Background of the Problem:
I was on OS 2.1.2 rooted with twrp recovery. (was really happy with my phone)
MM 3.0.2 upgrade comes and i decide to upgrade my phone manually (since ota was disabled due to root)
All goes well in first try..(did a dirty flash) OP2 3.0.2 runs smoothly
However, i found out i had lost root and couldn't boot into recovery.
I ignored for a month when i decided it was too hard to go on without root now..
So i searched through a few forums, went into fastboot tried oem unlocking.. failed.. Stuck hard in the bootloop..
Searched for about 3hours and used the MSM tool to finally unlock bootloader.. but still stuck at bootloop and no luck with recovery.. I couldn't boot into my installed rom(3.0.2)
I flashed recovery from OOS 2.1.2 or 2.0.1 and booted into recovery and flashed 2.1.2 again..
So now, 2.1.2 runs fine on my phone
I have refered to these guides/files while trying to install 3.0.2 or trying to recover my phone

PROBLEM:
Whenever i update my phone to 3.0.2, it stucks at the bootloop (showing oneplus logo and cmd showing it in fastboot mode)
i lose recovery and rom
i have tried flashing grarak recovery and hybrid recovery (both of which i believe are modded recovery for OOS MM)
In cmd, fastboot flash command completes without any problem but the phone doesnt boot to recovery and both give an error while giving the fastboot boot command
" downloading boot.img
OKAY
booting...
FAILED (remote: dtb not found)"
finished. "
Please suggest me something so that i can boot into 3.0.2 without bootloop problem.. 3.0.2 runs really smooth..
and additionally if possible, i would like to root but thats secondary.
Thankyou guys in advance. Please help a brother out

Heyy.. Thanks a lot Jyoti_re! It worked out perfectly..
I have done till step 3.. The phone booted into 3.0.2
The sensors are not working. I will flash the presist.img as you said in step 4
However, i have encountered a problem. My OP2 is a 64 GB version. But now the internal storage shows 7gb free out of 9.66 GB.. Earlier it used to show 54GB instead of 9.66..
What should i do?
Thanks again

Yes u must have to flash persist.img via firstboot mode by typing [ fastboot flash persist ] for sensor correctly working.
Install es file explorar from play store and check which folder taking More space
don't forget to press thanks if I helped u.

Thanks a lot Jyoti! /
Yeah i got it.. Flashed the persist img.
i searched through the forums.. somehow my device got the 16gb version img.. i dont know how..
i had to flash userdata64G.img as well
Now it all works perfectly.. sensors are working.. data storage is back at 54gb..
Thanks a lot! I had been stuck on this bootloop since 3 days..
and i pressed the thanks button.. i will press it 100 times over if possible Thanks again! Cheers!

Just to confirm.. Can i flash supersu via recovery now to get root? i hope it wont lead me to bootloops.. If there is some specific supersu file to flash for OOS 3.0.2 please guide me to it.. Thanks!

When you are in fastboot mode..
Try giving the command
"fastboot continue"
or
"fastboot reboot-bootloader"
"fastboot continue"
(without quotes) if your system files are not corrupt, it will boot you into your rom.. and then enable oem unlocking from settings

Tried this commands and the system reboots and stucks on the screen powered by android.

Are you mentioning that your device only boots to fastboot now? If you press 'start', does that boot to system or not?
Which stock ROM did you flash, and can you confirm if the flash worked? How did your device brick in the first place?

As siddhesh9146 had mentioned, the Athene stock ROM cannot be flashed in stock recovery, it is not a flashable zip file. You need a computer and ADB set up, extract the zip on your computer and use the flashing commands in the fastboot ROM thread to flash a stock ROM.
Until you've flashed the stock ROM, I'm not even sure if you have stock recovery, or a stock system on your device. The supplied blank flash does not appear to have a functioning recovery included with it.

So, you booted your device to the bootloader screen (not to recovery), connected your device to your computer, and you've flashed using the OEM_flash script, and yet you're unable to reboot to recovery?
Sounds like your stock ROM flash did not work the first time, leaving you without a recovery or a system. Try the following just to confirm:
1) Ensure your adb folder contains the extracted NPJS25.93-14-8 stock ROM (all the files), should be about 2 GB for the stock ROM. Also confirm that the OEM flash script is in the same location (so your adb folder should have the stock ROM, the flash script and the adb and fastboot.exe and adb.dlls)
2)Reboot your device to the bootloader (power down, then press the power and volume down keys to boot to bootloader) and connect your device to your computer.
3)In the adb terminal, type 'fastboot devices', without the quotes. If communicating, you should see your device respond with its serial number.
4)If communicating, run the OEM flash script again.
5)If your device does not boot properly, then reboot to bootloader.
5a)Copy each of the commands from the script (you can open the script in a text editor) and paste them in the adb terminal window and run each one by pressing Enter on your keyboard. You should see the command report [OKAY] if it's flashed. Any errors, let us know, that might point more accurately to what might be going on.
As an aside, this is one of the reasons why downgrading isn't a good idea....
