[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.

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?

flash the factory img
edit.. nevermind, i see ive already said that

Nexus 6 bricked and locked bootloader!?!?!?

Hi
I was side loading the new 5.1 to both my N5 and N6. N5 was ALL GOOD. N6 however is not. After waiting for a rediculous time for it to reboot when it was stuck on the white Google Image, I disconnected the USB cable. Now it won't boot past the Google screen at all.
I can see it as a fastboot device and can boot into bootloader. There appears to be no recovery. When I try to re flash or side load, I get the warning along the lines of 'unlock before flash'.
So........can anyone assist please?
Thanks in advance of responses.
Cheers
Thommo

Look here..
http://forum.xda-developers.com/nexus-6/general/fix-fix-qhusbbulk-cm12-t3059518
That might help, otherwise since you can get into BL mode can you try flashing stock recovery from the image you originally had? I guess I don't know if that works or not or if that is what you were trying to reflash..
fastboot command to flash recovery is
fastboot flash recovery recovery.img <--replace recovery.img with the name of the recovery you are trying to flash. It's most likely recovery.img if you are taking it from a stock image.
Good luck.

i have the same prob bro i am waiting for a fix i still have hope

So the lesson learned is: Always unlocking the bootloader once you have the phone/tablet should be the first thing to do so you can fix issues !

I also need someone to find a way to unlock the bootloader ! btw try booting into recovery (it will say no command) and then hold the volume up and power for 10 seconds and then let go, then select adb sideload ...let it time out...then try to clear data and cache. I tried to clear that when i had a bootloop but wouldnt work, i got it to work by selecting adb sideload and then letting it time out(takes a while to timeout)..must mount the partitions...

If you do not have TWRP recovery, there's nothing you can do. RMA.

Doubt it. There are some GooglePlay versions that have been RMA'd as it was a promo. Still gonna go back to original Account for the RMA.

stupid question . if this is Motorola you cant use RSD this with the correct FXZ. or they no longer use this since its a nexus.

Locked bootloader and can't boot into ROM or Recovery. (Fixed!)

Well, I really did it this time. In my efforts of messing with the M Preview build and trying to eliminate the "verification failed" startup message I made the mistake of locking the bootloader. Now the phone will not boot into Android or into Recovery. I'm stuck in Bootloader and it won't let me "fastboot OEM unlock" the device because in order to do this you need to boot into Android and tick the box to allow OEM unlocking (which I also unticked before getting into this mess, like an idiot).
EDIT: Got it resolved!
In order to get into Recovery I had to use the following commands in the bootloader:
fastboot format cache
fastboot format userdata
After doing this I was able to boot into recovery. However, recovery showed 0MB available storage and wouldn't mount /data, which prevented me from installing anything. It also wouldn't allow me to copy anything to the SD card using Android File Transfer or ADB sideloading.
To solve this I went into "Wipe" while in recovery and did a full format (the one that requires you to type "yes" before proceeding"
After doing this and booting back into recovery, I had full storage space back and recovery was able to mount /data. At this point I just copy/pasted the 5.1.1 ROM onto the sdcard with Android File Transfer. Once installed, I flashed the ROM and it booted right up.
I then skipped through the setup to get to settings and in developer settings I ticked the box to allow OEM unlocking. After doing that, I booted back into the bootloader and used the fastboot command "fastboot oem unlock" to unlock the bootloader again.
Once that was done I was able to use fastboot commands to flash the M preview all over again.
Hopefully you don't find yourself in this mess, but if you do, I'm hoping the above solution works for you.

Is TWRP installed?

WAIT!!
I did the following:
- fastboot format cache
- fastboot format userdata
And the phone now boots into TWRP. It won't boot fully but it will boot into recovery. I'm trying to sideload a ROM now but I can't access the storage.
Edit: enabled ADB sideload so I can ADB push a ROM to the SD card to flash. Does anyone know the exact root folder name for the sd card to pusht he ROM to? Is it /data/media/?

I did something similar this past weekend while trying to do the 5.1.1 upgrade with the OTA files before the Factory images were available.
Try and use the WugFresh tool to wipe the cache and such, and try some of the other obvious settings in the tool.
It was late and I'm not 100% sure what I did but I do remember reflashing the LRX22C from the factory image using the tool. Everything I did was from the tool minus the 5.1 OTA that came through once I was able to get back into the device. From there I was able to unlock the bootloader again.
I was worried myself that I might have to send the phone back but I just kept trying, don't give up just yet. I've been told many times it's almost impossible to brick an android device now a days.
Good luck!

However, I was able to ADB push the ROM to the SDcard. But when I try and install the ROM it gives me a bunch of errors saying "unable to mount '/data'" and "unable to mount storage"

Assuming you tried ticking data in twrp mounts...
In twrp, try and format data again. If that fails, try to format it as another file system such as f2fs before formatting it back to ext4

Success!
TWRP was also reporting 0mb available storage. I went into Wipe and performed a full format. Booted back into recovery and storage was showingt he full amount again. I was then able to plug the phone in and enable MTP and drag/drop the 5.1.1 ROM onto the SD card. Just flashed it and it booted right up!
I'm going to update the OP with all this info just in case someone else runs into the issue and needs help.
Thanks for your help!

Hi,
I faced the same condition like you experienced, with some differences:
- the phone stuck in "Google" logo
- stock recovery is accessible from bootloader
- I am unable to mount sdcard or install rom from sd card, but could conduct adb sideload
However, am stuck with verifying update package showing :
E: footer is wrong
E: signature verification failed
any ideas what to do next?
================ edited- add below info on how I got stuck
So my N6 was still on 5.0 (has not been updated to 5.1). I decided to try the M preview. I downloaded the preview, and began the process as follows:
1. reboot into bootloader
2. fastboot oem unlock
3. flash-all (success on loading the bootloader and radio, but error on updating the image)
4. hence i followed to flash individually:
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase cache
fastboot flash cache cache.img
5. and comes the stupid thing ! --> fastboot oem lock (really really regret why I did this)
6. and then once reboot, it stuck in Google logo forever
However, I am still able to access:
- bootloader (fastboot recognize the device, but wouldn't allow me to fastboot oem unlock)
- able to go to stock recovery, and as mentioned above:
I am unable to mount sdcard or install rom from sd card, but could conduct adb sideload
However, am stuck with verifying update package showing :
E: footer is wrong
E: signature verification failed
I tried to adb sideload the M preview image and 5.1 LMY47I but both showing the above error....
hope you can shed some light on this...

A solution to what? Keep in mind your problem may be different from the OP's issue, so if you want people to help you it's necessary to provide plenty of information, such as what you were trying to do, how you tried to do it, and any other information that you believe may be useful.

OK What i was trying to do was to flash a stock recovery, i start it by running the flash-it all.bat file in the factory image zip, it changed the user interface of the bootloader after first reboot and and had an error for "archive: recovery.sig not found" (something like). the phone status shows Software Version: Modified and fastboot oem unlock dont give the confirmation.
and
now my phone wont even boot to the bootloader, everything turned black. please hellp!!!!:crying::crying:

If you can't even get into the bootloader (volume down and power) you may have to have the device serviced. Do you get a response when you type "adb devices"?

Maybe it just crashed at a black screen? Does a very long press of the power button (over 10 secs) cause it to react?
Or maybe the battery is empty? Try connecting the power supply for some time.

i did that but no response.

The very dead battery is a real possibility. The thing is, using the charger that came with the phone isn't going to help. If you think the battery being dead is a possibility, you would need to plug the phone into a USB port on a PC, that is a very slow charge. Leave it on there overnight then unplug and replug. If the led at the top of the screen lights or the battery icon shows on the screen, you have hope. At this point using the original charger should get the battery going again. In this case, plan on replacing the battery.

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.

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?

I can no longer reach the boot animation?

Hello, XDA forums. I was trying to get Miracast to work on my cousin's Nexus 6 device; doing sone research I found that it was as modifying a value in the build.prop file. Naturally, I was like "Pshh, easy!" (Note that the device was already rooted.)
So I download a build.prop editor and apply the edit, save the file. Superuser request, granted, saved. I noticed that the editor now displayed build.prop as an empty file, but still had the values loaded; okay, whatever.
I rebooted the device to apply the changes. It was stuck at the Google post screen and had not continued to the boot animation.
After waiting a couple minutes I realized there was an issue. Okay, so I would just use the adb interface to replace the build.prop file with the stock file, easy, no issue. Turns out when I rooted the device a while back I never flashed CWM or TWRP, so I had to get into the backup recovery, since attempting to factory reset from the bootloader resulted in the same as a normal boot.
Once I had gotten into the backup recovery I plugged the device in and attempted to update the build.prop file. I couldn't get further than 'adb root', it would result in an error for every command except sideload and USB. I tried for quite a while to resolve that issue.
That wasn't working so I was like "I'll just flash the OS since I have the ability to sideload", so I flashed the stock Nexus 6 ROM and still had the same issue.
Does anybody know of a solution?

@Drasid,
Download the factory image from Google developer site. Extract all the files. Fastboot flash the system, and boot image files from bootloader.

@cam30era,
I can do this with the stock recovery?
I can only secure an adb connection through that; fastboot commands do not work in it.

No you use fast boot to flash factory images, adb to push a factory ota file

@Holeibdalip, Oh yeah, I was explaining the issue then my friend then realized "Wait, you can't fastboot like that, you fastboot in the bootloader."
It was one of those "Duh" moments.

And if you reread carefully what I wrote, I said "fastboot flash"....

Happens to the best of us lol

Alright so I reinstalled Android and it worked. Though on the setup page it said that my cousin couldn't log in and had to wait 24 hours (FRP). So, we waited a day and it persisted. I did some research and found a couple ways to fix it. Using adb I launched the settings app and performed a factory reset in the os. I still got the error afterwards, though I read that would fix it. Then I wiped the partition which is supposed to contain the frp information, that didn't work. I also tried to enable OEM unlocking in the os so I could fastboot OEM unlock and fix it, though the developer options appeared empty. I am unsure what to do next.
Edit: I flashed the system with the google developer image and reinstalled it, I got it to work, thanks for your guys's help.
