[Q] fastboot - no boot or img file

hey guys i'm having some trouble. i just got the nexus (it's my first smartphone, ever) and i've tried to hit the ground running. here's what i've done to the phone so far.
i got all the drivers running on my win7 machine and also installed the android SDK folder onto C: as was described in this thread: http://forum.xda-developers.com/showthread.php?t=878786
i then unlocked the bootloader using the above guide as well. when I power on the phone using UP+POWER it says UNLOCKED.
I then proceeded to follow this guide: http://forum.xda-developers.com/showthread.php?t=875875
i used ADB to flash the clockwork crespo recovery. i then used fastboot to install Superuser.
at that point i had an unlocked bootloader, clockword recovery image and superuser permissions.
i then saw that the 2.3.1 update had been released. i wanted to learn how to tackle that so i started reading up. i noticed that people were using ROM Manager and Titanium. I got titanium and installed the BusyBox addon and it allowed me to do a full Batch Backup of all my programs, etc. i've got the 50MB or so backup folder on my PC now.
anyway, i then messed with Rom Manager. I installed the 3.0.0.0 ClockworkMod Recovery and everything went smoothly. now this is where my troubles begin.
when i go to Download ROM all i get is a Free Stuff area.
when i go to Check for ROM Updates it tells me my device isnt set up for OTA updates.
those are just minor issues.
this is the big and scary issue i have:
when i click on reboot to recovery, it takes me to the same screen that i go to when i power on with VOLUME UP+POWER. it doesnt take me to the recovery screen that i see in various youtube videos. instead, i'm at the main screen where it says UNLOCKED and i have 4 choices (reboot bootloader, recovery, reboot, power off). and on the very top in RED letters it says fastboot - no boot or img file. <-- this is the part that makes me nervous. If i manually power down the phone and boot to fastboot and click recovery, it just goes back to this same screen and says fastboot - no boot or img file. when i first rooted the phone, clicking recovery actually took me to a different screen where i was able to load up superuser.zip and install it.
did i accidetnally delete something that i wasnt supposed to? did installing ROM manager mess something up? i typically dont do anything until i confirm that i am supposed to. i think the problem is that i dont yet know how one thing i do on the phone affects another. i'm guessing when i used rom manager to update the CWmod it changed some folders/files? i dunno!
otherwise, the phone works fine and there are no glitches or hiccups or crashes. So if someone can please take a moment to just explain to me what i did wrong or what i failed to do i'd really, really appreciate it.

you don't have a recovery partition. Either flash one over manually using fastboot, or boot up and try to use ROM Manager to flash CWR.

when you say flash one over using fastboot, do you mean put my phone using VOLUME UP + POWER, connect usb cable, then use command line to do this:
fastboot flash recovery recovery-clockwork-crespo.img
?

Yes, 'cept it will be "fastboot flash recoveryrecovery-clockwork-3.0.0.0-crespo.img" without the quotes now.
But does it say that you're missing a boot.img or recovery.img?
Also, the "not set up for OTA" thing isn't for official OTAs. Some developers have made their custom ROMs capable of being updated that way.

thank you luxferro and unremarked. i did it and it works perfectly. i am now able to access clockworkmod recovery 3.0.0.0. next step is backup my existing ROM and also to figure out how to put the OTA 2.3.1 on and restore all my data
oh and unremarked: it basically said no boot or img file and thats it after i would click on recovery or reboot to recovery trhough rom manager. it was just in red at the top. but now it takes me to the ClockworkMod Recovery

I'm bricked .. Getting worries. (Yes I've read the forums ...)

Attempted to flash Liquid Jelly Bean, then got stuck on the animation boot screen. I've tried Root tool kit for unbricking and setting it back to stock. Tell me it's successful but stays stuck on the animation screen.
I've also tried to unbrick manually however even though I have the correct files placed in my Platform Tools folder of Android SDK ... I constantly get stuck at the CMD prompt steps. Any time I type in "ADB reboot loader" or ..."fastboot flash bootloader bootloader-grouper-3.34.img" or anything similar I get the error message in CMD saying "___ Is not recognized as an internal or external command"
I'm not sure what to do. The bootloader does say that my device is locked, I just can't get passed the splash screen!

Here's an update:
I think I've made it worse ...
Nothing will boot now and it's currently locked. Any time I hit "Start" it says "Booting Failed"
My CMD now says; Error: Cannot Load "Bootloader Grouper-3.34.img"
I'm seriously lost. I've been working on this for about 6 hours now ....

Can you get into bootloader and then recovery by holding the power and volume down buttons? Was ADB actually working before all of this??

No I can't get into the recovery at all. When I turn on the device I don't even need to use the rocker keys to get into bootloader either. Actually my bootloader is a bit different now too. I have the 'Google' logo and at the top the regular options for Start, Recovery, Power Off, etc.
In simple terms: I can't even get to the animated splash screen anymore

Open the command prompt IN the directly WITH fastboot
Fastboot oem unlock
Then wipe / flash factory images. Fastboot -w update image whatever the image name is.
Then uninstall / delete that stupid toolkit and never use them stupid craps again.

Are you still able to communicate with the device via fastboot? If you issue the command 'fastboot devices' does it return a serial number?
Edit: I'm going to bed so if you are able to use fastboot, download the factory image pack from https://dl.google.com/dl/android/aosp/nakasi-jro03d-factory-e102ba72.tgz
Extract the archive. Inside are there will be an install script, manually issue the commands contained in the script in fastboot. The only thing you need to add is the location of the .img and .zip files from the archive you extracted e.g. 'fastboot flash recovery c:/Users/name/desktop/recovery.IMG'
There is no reason this will not get you up and running again.

Thanks for your response.
I've followed the instructions in the file. From previous research, I've had these files. My device does communicate with Fastboot. When I give the command for Devices it gives me my serial. Also, when I ask it to reboot-bootloader in CMD it does.
My issue is when I get to "Fastboot flash bootloader-grouper-3.34.img". CMD states "Error: Cannot load bootloader-grouper-3.34.img"
I've followed the commands previous to that. (Erase boot, cache, recovery, system, userdata)

Yes my device is unlocked again, but I still can't get into recovery mode. It just tells me "Recovery Failed" in small text in the upper left hand corner of my N7.

UPDATE:
After unlocking the device again. I used the Nexus Root Toolkit to restore to factory settings and it worked
The Problem: My device was no responding correctly to the toolkit when locked.
Cheers for the help. I'll attempt to root again, hopefully no problems this time If there are I'll be sure to post again!
Thanks to everyone that replied.

For the love of God..stop using the toolkit from here on out.. learn how to use ADB and Fastboot so you can avoid these issues.

So you erased the recovery then wonder why you could not boot into recovery....
You flashed or tried to flash the bootloader. You already had the same bootloader installed and there was no need to do so to try and fix your issue.
You still don't know what you're doing and are back using the tool that lead you to this issues. A toolkit. Learn what you're doing and you wont face this type of silly issue again.

Don't use toolkits. Most people don't have a clue what the toolkit is actually doing so if something goes wrong they aren't in a good position

Help, bootlooped! Locked bootloader.

Hello!
I have the Nexus 6P and I have successfully rooted 16 phones over the past 4 years and never had a problem I couldn't fix. Today I made a mess of my new phone.
I had a perfectly working custom ROM with an unlocked boot loader with TWRP (2.8.7.2) installed. I installed some custom soft keys and got into a boot loop. I went and flashed what I thought was the stock ROM according to the website I was following, and I re locked my boot loader like a fool and was going to eventually unlock it.... turns out I was still boot looped.
I have tried:
sideloading 3 different zips, always get the message "cannot read zip" whatever the zip is
I tried changing the names, doing the full names, doing a stock rooted zipped ROM, nothing works.
I have used SkipSoft and Wugs toolkit and I can't flash ANYTHING or transfer files onto the phone unless the bootloader is unlocked.
I have installed the Google drivers multiple times, ADB devices always works, it seems to not be a driver issue because I can do everything else fine.
I have let the phone sit for 35 minutes in bootloop waiting for it to come back online so I can tick that "OEM unlock" button in the settings menu.
I have also done a dozen other things, the problem is nothing I have done or tried allows me to get any ROM or any file onto the device to flash in TWRP.
Help?

ok shot in the dark here. I had a boot loop until I flashed the flashable vendors zip
I got it in this thread:
http://forum.xda-developers.com/nexus-6p/development/rom-pure-nexus-layers-fi-wifi-calling-t3244563
Give it a whirl if you haven't already.
Found this in the Pure Nexus Project thread, so props to them for providing this.

Thanks, the problem is I can't find a way to sideload anything or move a file over. Everything results in a myriad of errors.

at worst, you would have to invoke the flash-all command via adb once you extracted the couple of times that you have to. directions are on google's factory image site.
may not be the answer that you were looking for, but it always feels great having a clean device to work with. i mean as it stands, you would have to set everything back up on whatever rom anyway if you somehow got out of the problems you were having. you would spend more time doing that instead of just going the factory image route.
toolkits are fun, but learning your way around them is even more so.

I'm gonna check the flash all,I've never done that before. I think that would be all the images in the tgz factory image? Anything to get my phone back yeah, I just need it working again.
-UPDATE- I tried the flash all batch in the system image and I tried the flash all batch command and neither work.

Hey man - crazy story - I literally just got done messing with a toolkit and the EXACT same situation happened to me. Locked bootloader, bootloop, everything. What you need to do is do a complete wipe of everything in TWRP so you can access /data from your PC (unless it isn't messed up currently, and you can decrypt within TWRP, I couldn't...) Then, download Cataclysm (maybe something else will work, idk, but I just did it with cataclysm) and bam - it boots, head to developer options and get the box checked.
Stock images didn't work, nothing did... was scared I had a brick. The saving grace for us is that we both got TWRP installed. No more toolkits for me!

I have already done the advance wipe and the format data, I just tried again and my computer will not read it as storage with MTP enabled.

after extracting the tgz file, it should become a tar file. after extracting that tar file, it should become the six files listed below. these files should be in platform-tools to start from scratch.
bootloader-angler-angler-02.45.img
flash-all.bat
flash-all.sh
flash-base.sh
image-angler-mmb29m.zip
radio-angler-angler-02.50.img
once they are, open command line in that directory (platform-tools) and then "flash-all" should work. if it doesn't make sure you post the error that you're getting on your computer so that others can help.

I followed all these steps, I unzipped it and everything and put it in my fastboot folder. I still get the "unknown partition "all" " orrr flash is not recognized as an internal or external command, operable program or batch file. In an attempt with desperation I tried opening every version of the batch file, in the tgz and tar and unzipped AND in the fastboot and it all gives the radio img error.
I still do have my fastboot device connected, to my knowledge that means it can't be a driver problem right?

You can't flash anything in fastboot with a locked bootloader. The only way you can get your device to work is by using TWRP to flash a rom.

The flash all command doesn't work because the extracted tar file has A zipped folder inside that has to be extracted also with radio and I think recovery zipped up. You have to extract those two files to put them in the tar file and then you might be able to flash all. But as long as you can fastboot devices you should be able to flash all 6 files and have a brand new device.

1. did you unlock the bootloader again before doing all of this?

He can't unlock the bootloader without booting into a rom. He needs to use twrp to flash a full system but I am not sure how to help with that when he can't sideload.

just an unrelated question... why did you lock the bootloader again? what was the purpose?
also, as mentioned... locked bootlader, odds arre USB debugging and OEM unlock are also not checked.... afaik, youre in trouble... hopefully someone else can sav you, im out of ideas

Is there not a way to fix the sideload? Or a way to get my computer to read it as a media devices so I can transfer files or something? It's always worked with previous phones but my computer reads the 6P differently. (even when it was working)

Stop trying to fastboot flash anything, it will not work as I've already started multiple times. The only option you have is to get something moved to storage and flash it from twrp.

Bootlooping Nexus

My Nexus 6P is seemingly bootlooping.
I can boot into the bootloader menu but not into recovery. My bootloader is not unlocked so I cannot flash anything.
Issuing the command: "fastboot flashing unlock" does not work nor does "fastboot oem unlock". I cannot flash a custom recovery. Because my bootloader is locked.
Any help would be great.

You say that your bootloader was not unlocked, so I'm assuming you didn't have developer options turned on and USB debugging checked before fastboot flashing unlock?

Do you remember if you modded anything prior to bootloop? The reason you can't unlock bootloader is because USB debugging isn't on. What version of Android were you on when it happened? I believe you can still use google factory Image to restore your phone.

Since you don't have twrp you probably don't have a backup, which what I'm going to suggest will bring you back to stock and may lose everything. Though it's better than a bricked phone. Since I never did the flash-all.bat you may lose your stuff on internal SD. In this link, download the correct image your phone was on (under angler) and if using windows use the flash-all.bat in fastboot. If you're phone isn't 32 GB, extract all from zip and flash everything except user data. Forgive me for assuming you may be new. https://developers.google.com/android/nexus/images

Tried that. Continue to get the "Remote: (device is locked)" error every time it tries to flash a new image.
I'm not worried about losing any data on the phone. everything is backed up in the cloud.

Do you get the error on all that you try to flash? Maybe just try the recovery img only to see if you can at least get that. If that works you should be able to sideload ota through recovery. With having a locked bootloader you might be at a loss. But on the flip side, having everything locked and not rooted you should be ok for warranty replacement.

Fastboot is useless since your bootloader is locked. Try to ADB sideload the latest OTA image from Google and see if it will boot.

How would i get into ADB mode without being able to boot into recovery? I thought of this as well but haven't been able to find a way to boot it into an ADB mode

Ahh, missed that in your first post. I'm not sure how you can get recovery going if it's bootlooping when you access it.

Check out this thread at post number 268 they mention using adb through mtp mode when not able to use recovery.

Tried running through those steps. I can't even get a temporary boot of TWRP or stock recovery continues to bootloop even though WugFresh claims it was successful. Tried doing it manually via Fastboot and continue to get the error in flashing.
I just received my replacement phone. So I might just call it a day on this one. :crying:

Good to hear about replacement! There are a few people in these forums that have a brick and can't get out of it. I thought you couldn't Hard brick these phones unless that was your goal. And most of these users who have bricks don't even know what causes it. Just a random reboot then loops. Kinda scary.

How to Stock FW and Relock Bootloader? OP5

Hi all,
I've wanted to go back to Stock OS but when i type "fastboot oem lock" it says "FAILED <remote: Flashing Lock is not allowed."
Everything boots normally to OS 4.5.2. In DEV options the Unlock Bootloader is greyed out and says bootloader is already unlocked.
What can i do?
Cheers

These instructions did work for me with the OnePlus 3/3T. They should also work for the OnePlus5, just make sure that you download the OnePlus5 version of the software and recovery.

Thanks I asked the same question earlier glad u tried it..I want to make sure we can relock it before I get the phone. Did u enable oem unlocking in the developer options before doing a fastboot oem lock? Also, make sure you are on stock everything including recovery..

Hello. I first thing I do always is to install drivers. I start by connecting the phone to the laptop in charge mode, then in transfer files mode, MTP or camera. In this way he will recognise all the drivers your laptop needs.
Also I enter in fastboot mode and recovery so the laptop can recognise the drivers and always reboot laptop and phone just to double check.
What I did was: go to Developer Options and enabled Unlock Bootloader and USB Debugging.
Then I accepted the laptop request on my phone and all drives were OK.
I run CMD and typed fastboot devices to see if it recognises my phone and it displayed a serial number. So I proceed next to type fastboot oem unlock and the process went OK and on my phone it asked Yes or No to unlock and I choose yes.
Then I flash a twrp image by typing on CMD: fastboot flash recovery recovery.img (my twrp I'm had other name so I rename it. You need to enable "Show file extensions" in Windows so you can see what the extension is).
I then type fastboot boot recovery.img and the phone entered in Recovery Mode in this case TWRP.
My phone was always connected to the laptop and he open the internal storage window so I drag the supersu inside.
Then on TWRP I wiped dalvik and cache and I went to Install and installed the SupeSU on my internal memory root.
The phone then rebooted and ready to go.
But then I went to developer options and the Unlock bootloader was greyed out. I unroot my phone and flashed a stock recovery for OP5 and the stock image 4.5.2 and when I type fastboot oem lock it always says it can't be flashed.
I need to stock it since I'm giving to a family member and they don't understand much about phones and If there's a problem the warranty doesn't cover.
Just installed supersu to try an app. I never install 3rd party roms.

if your phones boots its not bricked... My guess is that you data is corrupted, i would wipe everything including userdata en reflashing the stock with recovery.

Hi right before your comment i managed lol.
I re-flash the stock recovery and in recovery i reset and wipe everything. then i install the OS4.5.3 by ADB Sideload and it's working now.
Just wanted to get rid of the inital warning that my bootloader is unlocked. I want to lock again.

I rooted my device with Magisk, and now I want to restore it to factory state.
I flashed stock recovery and OOS several times, wiped everything but fastboot oem lock failed all times (FAILED (remote: Flashing Lock is not allowed)).
Can you help me?
What should I do to relock bootloader?

here in this video u can see in detail how to lock bootloader. hope this help you
https://www.youtube.com/watch?v=CQYCSdDUdAU

HOW TO RELOCK..
Install TWRP and Magisk if you don't have them yet.
Magisk should allow you to slide "OEM unlocking" to "enabled"
Reboot to fastboot
Flash stock recovery via fastboot.
Run locking via fastboot flashing lock
Allow it to reboot and upon start up it will say device corrupted (THIS IS NORMAL)
Boot to recovery via the warning start screen.
Once in recovery, sideload latest FW.
Profit.

I usually do it this way (successfully):
Wipe everything but OTG in TWRP
Format data
Reboot to TWRP
Flash the full stock OOS zip
Reboot to fastboot
Flash stock recovery
Lock bootloader with the fastboot lock command

Has anyone made any progress with this? I too am having the issue as described and have tried the solution by Ricyksydhu, along with solutions from various other places around the net.
