[Q] Need to unlock bootloader, but borked device

Basically, I tried to flash the latest 5.1 image but unsuccessfully as the system.img wasn't extracted. For some reason I locked the bootloader and now I can't boot into a working system, and I can't reflash anything as the bootloader is locked. When attempting to unlock, it is telling me to go into dev settings to allow unlock.
Is there anything I can do?

Few threads about this today. Seems a regular user error. Can't think of a fix right now..

Can't be done.

Have the same problem and try to solve it with Motorola. No luck at the moment.

try flashing the factory img via your bootloader/fastboot

Can't. Boot loader is locked and requires a setting in android to be changed but android can't boot. Catch 22

Are you positive? I just flashed a Nexus 7 from 5.0.2 to 4.4.4 with fastboot. fastboot oem unlock worked without checking that box.

Damn, that's really lame...

Wow this craps really ticking me off with this update and all. I have been rooting modding for years and every damn time I get a device that uses fastboot I get nothing but trouble. I hard bricked three devices in the past with fastboot and it seems over the years fastboot hasn't gotten any better or easier. What a shame I love the nexus 6 but I'm seriously starting to reconsider and going back to the good old Odin devices.

I'm an idiot.
I made the mistake of trying to update my Nexus 6 (Stock 5.0 encrypted, rooted, Xposed) while talking to AT&T customer service on my other phone. Distracted flashing is a bad idea. I am sure I made SEVERAL mistakes.
I too was trying to flash the new 5.1 image and got an error when running ./flash-all.sh (I'm on a Macbook). Friend suggested I try to do it by flashing the boot.img recovery.img and then system.img manually. Got the boot to flash. Recovery flashed. System failed. Unfortunately I have closed the terminal windows and don't have the errors anymore. When it failed it said something about insufficient space. So (I'm assuming this is where I f**ked up) I hit start from the boot loader screen to boot into the system and delete some things even though I had plenty of space (over 20gb). It booted fine. When I went to reboot into bootloader, I accidentally selected recovery. It booted back into TWRP which confused me. I thought best bet would be to wipe the device and start over fresh. I wiped everything and booted back into bootloader... blackness. Now I have no response from the device at all. Nothing. No response from the power button. Nothing when I plug to a charger. Just blackness. Just a pretty, 2 day old Nexus 6 (warranty replacement from T-Mobile on Tuesday).

You wiped the boot partition too? Ouch...
Last time I did that, it was with my Nook Color. Thankfully that was able to boot from SD cards...
I have a similar problem with another Nexus 7 right now. Flash went corrupt, won't boot at all. No bootloader, no Google logo, nothing.
My only hope is that the device still talks to the computer, it shows up as a Qualcomm device under Ports in Windows Dev Manager. QPST picks it up and says it's in download mode. If I can source the hex files to flash, I think I can bring it back. I'm only sharing that because it might be your only hope too. Godspeed, sir.

lol, whats so hard with fastboot? fastboot oem unlock is rocket science? how about fastboot flash recovery recname.img? only way to hardbrick with fastboot is to flaah something to your device that doesnt belong there, or flash something into the wrong partition. how did you "hard brick" with fastboot???

The problem is that bootloader got relocked, and the OP is unable to get to the setting to enable oem unlock. Fastboot is errors out saying to Check "Allow OEM unlock", and FAILED (remote failure).

I would find it hard to believe that there is no solution to this. With all the bright minds here on XDA, I'm sure it can be figured out. The unlock setting must be stored somewhere, and it should be accessible.
When I first got my Nexus 6, I booted into the bootloader right after taking it out of the box (i.e., without booting into Android), and I was able to unlock the bootloader without having checked "Allow OEM unlock" in developer options. This could mean that the setting could potentially be located in /data somewhere.
OP, have you tried a factory reset in recovery? Have you tried playing around with the other bootloader menu items (e.g., "Factory", etc.)?

Thank you for taking a look at my post. I have tried all the options in the bootloader menu with no dice. Things aren't looking promising for me...

You're all using the newest fastboot?

Nexus 6 - Can't boot TWRP recovery

I was trying to fix an issue with my phone the other day, and saw that re-locking the bootloader might fix it. Nobody mentioned anything about it completely wiping the phone, including the internal SD card. I set most of the stuff back up again but realized that it was suffering from the bug on the old radio version that causes it to lose LTE randomly.
I went and rebooted into TWRP to try and flash it, and TWRP showed a completely empty sdcard partition and said it could not mount '/data'. I enabled "require pattern to boot," thinking it may not have known to decrypt the partition without that, and now I can't get into TWRP at all. I tried disabling the "require pattern to boot" option again but no luck. It shows the "Google" logo for about 5 seconds, then the blue "TEAMWIN" logo for about 3 seconds, then reboots to the "Google" logo and proceeds to boot normally. I should note that I have CM12.1 installed, and the latest TWRP. I've tried reflashing TWRP and that didn't help; I also did "fastboot format cache" and then "fastboot flash cache cache.img" using the stock factory cache.img. I got the radio flashed using fastboot, but I'd really like to have a working recovery.

no working recovery with a locked bootloader, sorry. if the bootloader is locked, you cant flash anything. its locked. to flash things, you need an unlocked bootloader. its like locking a door, but expecting it to open magically when you walk up to it.

I forgot to mention that I re-unlocked the bootloader. I can also boot the OS so I'd be able to enable OEM unlock again if needed.

All the console output indicates success, and it boots to the initial "TEAMWIN" logo for a few seconds and reboots.

Briman, I seem to have a similar issue on my and wife's Google Nexus 6s. I unlocked and rooted using Wug Tool Kit I used in years past with seamless success. To confirm root CM 12.1 I can get into bootloader, Teamwin. From there I am to flash the Superuser, Busybox and TWRP zips under SD\iReady to Flash\Rootfiles..... Only I am not given an option on the menu? I am struggling with using the command prompt and proper paths from SDK Tools so that is not an option at this moment. I see a File Manager that shows this path but am hesitant to use it as I have READ this could cause damage ( brick) to the system. Watching your thread for answers or possibilities. I know the senior members as Simm22 dislike tool kits and so do I. I am simply trying to grow and learn.

na, toolkits work fine. sure, they occasionally do mess up, but its not very ofver. i generally like ut when noobies do the rooting the correct way the first time, that way they can learn some basic things about how everything works. then, they can yse toolkits all they
btw, teamwin isnt your bootloader, its your recovery. team win = twrp. now all you need to do is download the latest supersu and flash it via your recovery, and the you can install a busybox app from tbe play store, and use it to unstall .

I followed your directions while working on my Nexus6 phone. Was able to access bootloader then install iReady files. Worked perfectly and phone loaded SUPERUSER, BUSYBOX & PERM RECOVERY. Not so much on wife's Nexus 6. I get thru UNLOCK & ROOT w/custom recovery on the Wug Fresh Tool Kit. At RECOVERY menu pulls up SD - Up one level. No option is allowed to continue on and load the three mentioned packages. I then able to reboot to system. Does it appear I am bootloading but not fastbooting? Will try and insert images.

one question.. what is perm recovery?? the only recovery that works on the n6 is twrp recovery.
and when you are in her recovery, is it showing you the right location where the files should be? if nit, you csn change the lication.

Simm & Others. Thank you for your good words and suggestions. It would be easier for me to list what I did not attempt rather than what I did try. . I tried nearly most functions in the Wug Fresh ( by Harold) v2.0.5 after failing to find the correct command prompt to use ADB. What happened is an odditity. Mind you, I've been on these two Nexus 6 phones for 4-6hours a day for about ten days! Day later, Happened to be waiting for wife in parking lot and picked up phone and pressed SuperUser. Viola! It went into TWRP and gave me an RECOVERY option. On impluse, I flashed TWRP and Superuser zips. It took and processed. however, the best part of this is the hands on learning experience of booting, flashing, wiping, language, terms, SDK, Android and more. Once I figure out my path problem on my windows based PC to loading ABD commands I am continuing my self study of Android and App development. How do I get the packages out of the SDK Tool Kit to folders in PC? Thanks all.

your welcome, but you are still off in one bit of fact. you use fastboot, not adb, to flash a recovery(and system.img)
edit.. you can use apps like flashify to flash recovery, if you have root already.

So BOOTLOADER is the USB connection between the device and PC. FASTBOOT is the process via we make changes in the device via the PC. ADB is the device language via which we communicate. So do I still need to flash a system recovery image? Flashify App? I already went thru install>iready to flash> superuser (version)>busybox>flash>reboot>system. I'm going cross eyed from reading. The wiping part worries me as I fear formatting or deleting essential data.

ok, when wiping, dont do the first option wipe, itll wipe your whole phone clean. you need to select the advanced options and pick what you want wiped. fastboot is the way to unlock your bootloader, or flash a recovery. also, you use it to flash a system.img or any part of it.
adb is a general linux that can be used with android, anywhere but in the bootloader(only fastboot in the bootloader).
bootloader isnt the usb connection between the device and the pc, its part of the phone that boots it and decides if the rom is safe to run. thats why we unlock it. so we can flash roms eithout googles key.
fastboot is the tool that you use to do whatever needs to be fone in the bootloader, adb everywhere else.
a recovery you need if you want to flash custom roms, kernels, supersu, or other mods. you can also wipe different partitions with the recovery, or make a "nandroid' backup. thats a bavkup of everything. its like a complete snapshot of everything during the time you made it. if you ever mess up your phone, you can restore it, and you will be at the exact same place when you made the backup.
anything else?

Help with Nexus 6 possible Brick

Alright I am looking for some help here. I was attempting to unroot to update my Nexus 6 to Android M. Not sure how this happened but here it goes. I can boot the phone into recovery TWRP and into boot loader but the OEM is locked....In recovery I have no backups or ROMs o flash and my mac is not connecting with the Nexus 6. It seems like there is no ROM on the phone at all and I cant use Terminal commands I keep getting Failures. I have run the 1 click root and unroots for mac and still nothing. I also have no access to Developer options since I cant load into a ROM...So I cant select allow OEM unlock... Please let me know if there is anything I can do to fix this. Thanks for your help everyone!

Try to uninstall all drivers then re install to see if mac recognizes your phone then sideload a rom to recovery or adb

Had this before. I believe when connecting to your computer, you have to delete every nexus 6 previous connections so it would be as if your phone never connected to your computer before. Then after you do that, it should install drivers and recognize your phone. I'm not sure if I remember correctly but I believe its from your toolbar on your computer where it normally pops up "eject USB " warnings. Sorry if I couldn't help

Delete all drivers relating to Android. Download and install the Android SDK Tools from Google. Update the SDK and install the Google USB driver. Boot into TWRP, connect the N6, then use adb push rom.zip /sdcard.
I think that should work.

or fastboot wipe user data and cache.

I have been working on this since last night 7pm... I tried adb push and it just sits there and says starting adb sideload for about 10 min then vibrates with a cancellation. I tried removing Android File Transfer and reinstalling it and I still get the can not find device error. Im thinking this might be a loosing battle.

I did both of these to get past the TWRP boot loop. I can get into TWRP but its empty like everything has been wiped I have no backups or ROMs to flash to. Since the OEM is locked and I cant launch into a ROM to select allow OEM unlock it seems like im going to inevitably lose this battle. Last resort I have a friend coming over with Windows (hoping) WUGfresh can solve the issues....

did you have any roms on your phone before all this? if you did, did you try to search if they are in a different location in your storage now?

Do you have access a a Windows machine? NRT has an option to reflash a bricked phone. Never bricked mine but that tool has been awesome otherwise.

All due respect to the developer, but all WUg's NRT does is automate the downloading and the commands you use to flash manually. It doesn't do anything "special"

True, but have a Mac, and it is rare that being in recovery and connected to the Mac, do not recognize ....

FIX! we got it!
Thanks for all the responses guys! We spend another 4 hours on this Sunday and finally got it! We ended up using this forum step by step. http://forum.xda-developers.com/nexus-6/help/info-nexus-6-nexus-9-enable-oem-unlock-t3113539
While my friend was installing all of the ADB drivers on his PC I attempted the steps on my mac. It made it through the first to lines of code but when rebooting into Boot loader it came back with a fail notice to unlock the OEM.
When he got all drivers installed we used the same lines of code (modifying C: for the location he had the ADB drivers) and it accepted all codes. Seeing that screen change into the OEM unlock select yes screen was a GREAT moment lol. After that we used NRT to flash Marshmallow...
All in all it was fun trying to figure this out! Not so much fun thinking I had to drop another $300 to get a new phone! Again thanks everyone for the help!

Stuck in Fastboot Flash mode, Developer options turned off

I've followed all of the steps from this guide: http://forum.xda-developers.com/showpost.php?p=56938530&postcount=1
I've got to the end where I am running the code snippets to flash everything, but everything fails. The error stated is FAILED: remote failure. I am not sure if this is related to my developer options being turned off, but I think it might be.
Is there a way to turn developer options on while in fastboot mode or perhaps a way around this error? The reason I am stuck in the fastboot is because the boot image can't be validated, I am not at the fastboot by choice, haha.

No. If your recovery is still stock, flash the Android N Preview 1 OTA or an Android 6.0.1 OTA image from Google. One of those will restore your Nexus to operating condition, and from there you can try again. If your recovery is TWRP, flash a custom ROM.

I apologize for my ignorance since this is all new to me, but could you explain a few things to me.
Is this what you're referring to when you say Android N Preview 1 OTA: 'https://developer.android.com/preview/download.html'
Secondly, in order to flash these, am I still following the steps I was before, or should I be following a new set of steps?

You don't need the N Preview anymore. Download your Android 6.0.1 image from the Google page and flash using the instructions given on that page.

I went to the page and followed the directions. Still doesn't work. The flash-all script reboots after the first two commands, which lock the phone. But even then, it is still giving the error FAILED:remote failure.

me too!
I seem to be having the exact same issue! i just bought a Nexus 6 online that wasn't booting, it would only show a green led when plugged in. so here I am doing everything I can think of to fix the issue but then I get hit with the "remote failure" when i try to oem unlock the bootloader! (and since the phone wont't boot i can't check the "unlock bootloader" box in the developer options) so yeah I am going to keep researching this but if anyone has any good ideas about to get around the bootloader being locked please jump right in.
anyways I may have deeper issues, the battery will not charge. i know this because when i load up the fastboot menu, which i have to do by holding the buttons while plugging it in, it should say battery charging but all it says is battery ok
I also can't load recovery because when im in the fastboot menu and i choose recovery the phone freezes and the green led comes back on... *sigh*

They have the full ota packages posted on Google site now you can and push through the stock recovery
Here just make sure you get the shame version

I have the OTA. I also installed Wugs toolkit.
My phone is in fastboot mode due to the boot image not being able to be validated. I didn't voluntarily open up fastboot using the shortcut.
The phone is UNLOCKED until bootloader is rebooted, then it is LOCKED. If I click start, it becomes UNLOCKED again. Wug's toolkit tries to UNLOCK the phone even while the phone says it is UNLOCKED. I don't think the phone is actually UNLOCKED, however whenever it tells me it is UNLOCKED, I try to proceed with flashing and it gives me a remote failure message on each command.
The next thing I am going try is the drivers and Wug's toolkit has a driver option, so I will try that. Besides the drivers, any other ideas?

You seem to be inexperienced in rooting Android devices. If you aren't, I apologize for the assumption. However, you should learn how to use adb and fastboot without relying on the toolkit. Toolkits tend to hide diagnostic messages that adb and fastboot generate while running. This missing information makes solving problems much more difficult.

I am inexperienced, I stated that earlier. I have check a bunch of different forum posts and a bunch of different guides. Nothing seems to be helping and it seems like such a simple problem, a boot image that can't be validated. I am not trying to do anything special with my phone, I am just trying to get it to work. I woke up and it was stuck in this 'AP Fastboot Flash Mode (Secure)' mode. It is very bare bones, not even similar to the screens within videos I have seen. One moment the phone says it's UNLOCKED, the next it's LOCKED.
You are the expert, I am not. I am merely following your directions and they don't seem to be working. I did some outside research, came to a toolkit. Toolkits are great for beginners, especially since they are UI built, are built by someone who knows the area of interest, which makes researching easier and more efficient, but on top of that, it seems to be getting me much farther than your advice, although nothing is successful at this moment.
Here is a little more context into my situation. My phone seems to be recognized by Fastboot, but not ADB (From what I found, fastboot will find devices in fastboot, and adb will find devices functioning normally, don't know how true that is.). In addition, my phone seems to switch from UNLOCKED TO LOCKED after reboots, but can become UNLOCKED again if I push ANY button. Every command I issue (i.e flash bootloader, flash radio, flash system, flash userdata) result in the message, FAILED:remote failure, which I am not sure how to avoid (I have googled, checked these forums, checked other forums and there doesn't seem to be much, if any documentation on the error), but I think it is related to the fact my developer options are turned OFF. My next course of action is to install new drivers (I checked my drivers which are said to be up to date, I also installed google USB driver through the sdk, but now I am going to look into an adb or universal driver?) and attempt to rerun everything successfully.
If you have any other ideas, or don't think its the drivers, feel free to bring it up.

As a couple of fellows said before, try this:
https://developers.google.com/android/nexus/ota
Flash a FULL OTA from the link above, not a factory image. To flash any OTA you don't need to be unlocked. I think you might be confusing the terms (with the OTA you don't have to flash anything using fastboot)
In the link there are the instructions, it's pretty straight forward and easy if you have the correct drivers installed.

OTA requires that u can startup into recovery, I cannot I can startup fastboot through key combo but when I go to select recovery the green led comes back on and the screen displaying the fastboot options remains static
I think the phone freezes because it does not appear to be able to use the battery. though there is a firm battery connection it will not charge or power on without being plugged in. maybe when I select recovery I can quickly unplug and replug the USB and maybe hold the power button to try to simulate a successful reboot.. idk just thinking aloud and working with what I got..

I also can not start in recovery mode and the OTA requires ADB, which isn't recognizing my device. I have also stated that I have followed those instructions, and nothing resulted from them, except the same messages I have been stating these last few posts.

I will try this first chance I get later tonight..

Listen the ota doesn't get installed through fast boot, you have to select recovery through the fast boot then install the update by pushing it as bootloader does not need to be unlocked!

Ok, well it seems we are at an impasse. You seem to think I can do something, so I am going to show some pictures of my screen. Its going to be blurry because I had to take it with my computer, so I apologize, but I will elaborate on each picture.

The first two pictures are when the phone is 'UNLOCKED'. The second two pictures are when the phone is 'LOCKED'. The moment I press anything in 'LOCKED' mode, the little android man goes away, and it becomes the first two pictures. WHENEVER I push a button in 'UNLOCKED' mode, nothing happens, except in the bootloader logs screen says, 'FAILED TO VALIDATE BOOT IMAGE RET -1'. I have done everything on that OTA page in every way possible. It has done me no good.

Ok, I made a little progress I think. Wugs toolkit allowed me to use TWRP on my phone and ADB is recognizing my phone now. There are a lot of options within TWRP though, so I am going to look through them all for anything relevant. Anything I should keep an extra eye out for?

If you can use twrp just download a custom ROM to your phone and move it over to SD card and flash it, then you will be able to boot and unlock the bootloader in developer ootions, that is your best bet, if you keep getting force closes after flashing a custom ROM your going to have to do a factory reset from within twrp

I don't have an SD card, can I move it to the internal storage? And how exactly do I do this? I can't copy/paste anything into the phone (it says the phone doesn't actually exist, even though adb is recognizing it as in recovery) or do I sideload it? When I try to sideload it though, the device disappears (and device manager sees nexus 6 under other devices, but the driver isn't up to date and no drivers seem to work. I've tried the google usb driver with no luck.) and it won't allow me to sideload it.

Bricked phone

Hi
I've been so stupid that i locked the oem setting, without any OS an recovery.
By all that, i've been searching online for a solution for days, without any luck...
So now im back with a phone that's oem locked and can't unlock it because i can't allow oem unlocking in developer settings, and can't do adb push because i do not have any recovery on the phone.
Is there anybody that can help me?

Can't you get to the bootloader and fastboot the stock google images? This is a N6, right?

@ktmom: He can get to the bootloader, but it's locked, which means fastboot is not an option. Worse, he apparently has no recovery installed so he can't sideload an OTA.
The OP is screwed.

Yeah, spaced
What about running recovery on the pc? I've never done that. I guess it requires an unlocked bootloader also.
I dunno, this is an N9 thread as is this one, but if I was in this position, I think I'd read through these.

I didn't think of that. It may work. Then he can sideload.

Power up arrow to get into bootloader mode
might have to unlock bootloader at this point (dont remember the exact process you can google it) should be another fastboot command
fastboot flash recovery preferably twrp
then you should be able to load up a rom

How can i make a running recovery on a pc?
Tried to search for it, but i cant find anything on it

Code:
fastboot boot recovery.img
The above command sends the device into recovery mode using an image stored on a PC's hard drive. From there the owner of the device can use the recovery just as if it were installed in the /recovery partition of the device's internal storage. Files that the owner of the device wishes to use are stored in the device's internal storage.
It won't help the OP however. An unlocked bootloader is one of the pre-requisites.

Cant boot up a live recovery either, because of tge locked bootloader...
Anyone got other ideas? Im really lost with this one

Contact Lenovorola and pay for the privilege of having your device serviced. You're totally screwed.
