Unlocking the bootloader without access to the OS - Nexus 5X Q&A, Help & Troubleshooting

My Nexus 5X just corrupted itself a couple days ago and unfortunately I did not enable OEM unlocking before that happened. I was running stock, un-rooted and from looking online the past couple days I see no way to unlock the bootloader so I can wipe everything and re-flash. I can get into fastboot, but not recovery mode. Recovery mode just says "No Command" with the little android on its side. I have tried all the fastboot commands that one would normally try and they all return some version of "device is locked" error messages. Is there any way at all to unlock the bootloader or flash stock, or otherwise get into recovery without checking that OEM unlocking option in the Developer Options of the OS? I don't care about my data, I just want to get my phone working again. It's out of warranty so I am willing to try anything to get it working again.

I'm in the same situation

This is why I always enable Oem unlocking on all devices I own regardless of security for things like this .

Yeah, im going to be doing that from now on. I am pretty sure it was an OTA update that did it. It had just updated a day or two before. I was able to get into Recovery and sideload a different OTA update. The update failed and the phone rebooted, but it rebooted into Android. I was able to get my data off and all seems stable for now.

How did you fix it?!

I am in this exact situation. Phone out of warranty, just want to get it back on, don't care about the data on it.. but the "device state" is locked. I can get it into recovery but the sideload fails, I think because the device is locked. How did you get your phone to work again??
I've tried following these instructions (I'm new and can't post a URL: [ttps://drive.google.com/file/d/0Bz6x7k-VkpUJam5Mc1hKa09PVGc/view) and it fails during step 19.
I've also tried these instructions (I can't post the URL but if you google this exact phrase, it's the first link: Nexus 5X Bootloop Fix - The Step-by-step DIY Guide - TechBii) but the phone is locked so I can't do it.
Help!

So did you ever get it to work or just thre the phone in the garbage, @coryrwest

I'm having a similar issue, how did you exactly get it into recovery? Cause mine will simply keep rebooting if I select recovery mode from bootloader

[Q] Strange root problem, please help

Okay it's been a few months since this has happened so I'll try to remember as best as I can; I had rooted my Nexus using WugFresh's kit, everything went fine. It was rooted for about 6 months and eventually got stuck in a boot loop (no clue how this happened, I hadn't installed any kernals, roms, even apps in months). I tried like 4 or 5 different methods to fix the issue; I finally was able to get the phone working again using ODIN mode, it completely restored it to stock (as far as I'm aware).
So I tried to re-root the phone; no luck, using ANY method I've been able to find. The main problem is I can't seem to get into TWRP, every time I try to it simply gives me the dead android with the red exclamation point. I'm not an advanced user by any means, but I'm not totally clueless and I can follow directions. If anyone has any advice for me on this I'd GREATLY appreciate it, I have an excellent 4G signal where I live and the only other internet option is AT&T basic DSL so I'd really like to be able to use my wifi hotspot again. Thanks in advance for your time, I appreciate anyone who takes the time to try to help.
1) android on its back is stock recovery.
2) follow this: http://forum.xda-developers.com/showthread.php?t=1529058
it works 100% of the time if you read and take your time.
it sounds like you have root but cant flash a recovery, let me know if im wrong but if this is the case I would just download goo manager from the market and go into settings and flash a custom recovery and that should fix your recovery problem but sometimes you have to download the recovery twice ive noticed that in the past, let me know if this works for you or you could go through the longer process above but your fix may be very simple
Thanks for the info, I will try this either tonight or tomorrow and get back to you; I certainly hope it works!

This is driving me insane. I'm trying this method; I followed the directions step by step, but my phone is showing that it is unlocked already (when I entered the fastboot oem unlock command in CP it returned FAILED: Invalid Command, but it is showing as unlocked in bootloader.
Now for the weird part; I rebooted to bootloader and tried fastboot flash recovery recovery-clockwork-6.0.2.3-toroplus.img and it returned immediately FAILED: Invalid Argument. I decided to start the process over, and now I can't reboot from CP, it's saying error: device not found.
I really want to just smash this f*%&ing thing into several hundred thousand pieces right about now, so I'm going to take a break for the moment. Are there different types of bootloaders, or is it possible the my bootloader is just corrupted or something?
There are different bootloaders, but the fastboot commands should work just the same. You're on Windows i'm assuming? You could also look at efrant's guide, http://forum.xda-developers.com/showthread.php?t=1626895, as well as his 101 in the general section stickies. It does not make sense that the device would become not found, and I would try reflashing the bootloader. Don't smash the phone!
Have you tried this method?

[Q] Nexus 7 (2013) fails OTA update to 5.01 with Android Error

My unrooted, stock Nexus 7 was on 4.4. I received an OTA notification about 5.0.1 so accepted the upgrade. After the reboot and seeing the Android with the open stomach, it fails with Error against the Android. All I can do is long power off/volume up to power off and then power on again. It then reverts back to 4.4.
After about an hour I received another 5.0.1 update, went the same process and received the same error.
Does anybody know what that could be? I guess I could factory reset the device there is nothing on the tablet that hasn't been saved in my Google account anyway.
Thanks
Wanted to say I experienced the same thing earlier today, except I didn't get an immediate second chance at the OTA. I have the wifi-only version of the N7 2013, and it is also not rooted.
Browsed around the net and various places to see if others had this issue, but no luck. Not really sure what the problem is unless the download got messed up somehow?
Same issue here. Download the update. It shows verified. Reboots, starts to flash and then the android error
Reboot and it is still 5.0
Happy to report that when I got another crack at the ota the update went fine. Still confused as to what could've caused the problem though.
Well it killed my N7 it seems. Got the error message then shut itself down. Now it won't boot up no matter what I do. Any ideas?
My update just stays in the notification area. After the failure I just power the tablet off with long press of the power button and volume up.
I am stock, rooted and unlocked. I used the WUGS toolkit to flash the stock recovery assuming that this is all that was necessary for the OTA to be recognized and accepted. After flashing back to stock recovery, I rebooted the device and told the OTA to update. It starts going through the process and dies with "Error!" and reboots back into 5.0. I tried using the WUGS toolkit to ADB sideload, but I have not been able to get it to work. At some point, it actually got into the Stock Recovery, but ADB wasn't able to contact the device (that only happened once). Every other time, it goes through the script and shows the Android on it's back with the exclamation mark, and below it says "no command."
The device works, but it's frustrating. I wish there was just a way to fastboot the OTA, or just do it via TWRP.
I'm anxious to hear how others work through this, as it appears that I'm not the only one.

Tried sideloading the factory image?
Sent from my Nexus 5 using XDA Free mobile app
Since my N7 is a secondary device (my main device is a N5 which received the Lollipop upgrade fine), I might just leave it on KitKat rather than muck around with sideloading Lollipop. KitKat works fine for me at the moment. But it's really annoying that a stock N7 cannot get an OTA upgrade and goes into an Android error state.
I was on 5.0 rooted with TWRP and got the same error trying to take the OTA. So I downloaded the rooted rom found here http://forum.xda-developers.com/nex.../rom-factory-stock-rooted-rom-lrx22c-t2960745 , used Wugfresh's NRT 1.9.9 to update the bootloader, and then dirty flashed the 5.0.1 rom with TWRP. Painless and fast with no loss of data or anything.
Same problem! I managed to workaround the issue by using fastboot replacing system.img boot.img recovery.img with stock ones!

Are you suggesting that I blow away what's installed and just update by doing a fresh install? would prefer to not do that.
I did download razor-lrx21p-factory-ba55c6ab.tgz (the 5.0 factory image) and extract the recovery.img for it, and fastboot flashed it, and the no matter what I end up in the Recovery bootloop with the android on it's back and exlamation point and "No command."

If I am not wrong, there is a way of flashing the factory image without wipe by modifying one of the scripts, never did it though myself.

Turns out I was using the wrong key sequence for Recovery to get past that screen. Holding down Vol Up + Power for 3 seconds, then just pressing Power gets you to the right place. Am still having issues with OTA, as the system believes something was altered (install-recovery.sh). Others are saying that the way to do this is as described here: http://forum.xda-developers.com/showpost.php?p=57271130&postcount=423

jep, that's what I was saying earlier: factory image. For the 5.0.1 update you only need system.img and boot.img, at least that way it worked for me and my N7 2013 is running fine so far.
I dont get 5.0 on my nexus 7 2013, wifi, 32 Gb(flo, ktu84p)

Now I'm running 4.4.4 stock rom , locked boot loader and I unrooted it with super user unroot option. Can somebody help me why I don't get my ota?? Thanks ^^

Oh man! It's crasy, I was waiting so long, and exactly on this day when I write to thread I get my update!
EDIT: Never mind. I tried to do it via sideload, and it complained that the /System was too full. I rebooted, compared it to another Nexus 7, and the size was the same and free space was the same (and the other one updated fine). for the heck of it, I tried sideloading again, this time I formatted the cache first (no reason, just a thought) and that time it sideloaded correctly. So I'm up to date now... Weird.
I have the same issue. did a factory image install to 5.0. Now I get the update notification for 5.0.1 (as expected).
When I try to install it, it reboots, then I get "error" - have tried 3 times now. A reboot gets me back in the tablet, but am still at 5.0. This is my kid's tablet, so I have no need to root it or install a new rom, just want the dumb update to work correctly...

That is indeed strange...If you are pure stock it should work I guess? You could still try to sideload the 5.0.1 as well (did the same as I did not want to wait for OTA). You can do it without full wipe, just wipe cache in the process. (You need only to flash system and boot.img, wipe cache, reboot). Nevertheless let me know if you get the "error" solved, would be interested to know.

[REQ] Help: bootloop after 7.1.1 beta OTA and cannot enter recovery mode

I've been watching several threads for the last few days, and have not seen this exact issue. I would greatly appreciate some help.
Device:
- Nexus 5X LGH790 32GB
- Stock bootloader / fastboot
- Never unlocked / rooted / etc.
The only advanced thing I've done is join the beta program a few months ago to get 7.0 early. Got that without any issue.
Issue:
I received the 7.1.1 OTA on the day it came out. Installed with no problems. The next day, the phone just froze in the middle of regular use. After about 15 seconds, it started boot looping to the Google splash screen. I can hold volume-down to enter fastboot, but when I select recovery mode, it just starts looping again. Pretty much all I could do was power it off. I did find out by accident that if I left it looping for long enough, sometimes it actually loaded normally (I even saw beta program warning/notice). But when I tried using it for more than a minute, it would freeze, reboot, and loop again.
What I've already tried:
- I tried using the WugFresh NRT fix softbrick method. I was able to quickly turn on debugging one of the times that I left it to loop. But when NRT sent a reboot the phone, it threw it back into the loop and NRT stopped recognizing the device.
- I tried to follow the unbrick procedure using a TOT file in this thread: http://forum.xda-developers.com/nexus-5x/help/tutorial-how-unbricked-nexus-5x-16gb-t3481766 But even after using LGUP, I still cannot even get into recovery mode.
- I filed a bug in the AOSP here: https://code.google.com/p/android/issues/detail?id=225802.
I'm at a loss here. On another thread, a member suggested this type of loop was a hardware/solder joint issue. I suppose that's possible... but man, what a coincidence that would be! Just now after the OTA the hardware fails? Any other thoughts? I'm pretty new to a lot of the terms/methods here, so maybe I missed something.
Thanks, DCK.
Update: I tried using LGUP again. The phone still gets stuck on the Google screen then boot loops.
Now, however, I am able to get into recovery mode consistently. Other threads have suggested doing an OTA sideload at this point. But I cannot seem to get my device recognized. The NRT shows no ADB devices connected. So I'm still stuck. Is there another way to try sideload?

Try fastboot/bootloader mode and fastboot flash the OTA manually.
Update 2: Seems like all the other things I tried over the last few days have caused various unofficial USB drivers to be installed. I've tried uninstalling most of them. I downloaded the google USB driver from latest SDK. But my 5X is still recognized as a Kedacom device when it is sitting at FastBoot.
However, I must have made some progress because I was able to start the sideload process. Unfortunately, I am now stuck on yet another error. The phone hangs at "verifying update package" and then after about 2 minutes... it reboots itself and starts looping again!
I thought I had it. So close. Now I want to throw the phone. Going to sleep, but would be grateful for any other suggestions in the morning.
- DCK
use nrt to erase all partitions, then download 7.1 factory image, unzip and flash one by one the partitions.

Sounds like the boot loop issue many people have been having (the hardware/solder issue). It happened to me a few weeks ago after upgrading to Android 7.0. I got a replacement device from google.
If you're bootloader is locked, NRT or any other method to flash the factory image is not going to work. The only suggestion I have is to un-enroll in the beta program and hope your device will boot long enough to flash the ota Google will send the device to get back to 7.0. Note, this will wipe your device.

Help, might have killed my device

Not 100% sure of best place to post this, but I'm getting desperate now...
I'm pretty worried I've killed my device. After following the guide on how to root with Magisk, my phone is stuck on the white "loading" screen with a G logo. I've since tried to restart, but I can either go into fastboot mode or get the white screen when attempting to boot into android.
Tried to flash the latest factory image to fix it, but that couldn't get that to work. Now the phone isn't showing up on adb devices either. panicking a little bit here.
Does anyone know what to do?
ADB won't work unless the phone is booted into Android or in stock recovery for a sideload.
Does your computer recognize the device when you are in Fastboot mode and type "fastboot devices"? Try flashing the factory image again but make sure you have the most up to date platform tools from Google. Old versions are a common cause of issues.
Did you flash TWRP recovery or just boot to it to root? If you still have stock recovery you can try a factory reset from there but any modified images you installed might be the issue.
like Fury said, your platform tools need to be updated, same thing happened to me.
What didn't work when you flashed the factory image? Do you have the latest sdk tools version of fastboot and adb?

Thanks so much, this is where I was going wrong. Have gone into recovery and rescued it.
Tried the process again to get Magisk working, but ended up the same although this time the white screen only went on for a while before I got an error saying my data was corrupted. Tbh, after all the stress I'm just going to give up on this and live with the phone in stock. All my drivers and adb were installed and setup today, so everything is up to date.
edit...
Not out of the woods yet. After restarting the phone and going through the setup, it's not detecting the SIM card or any wifi networks. I've installed the OTA and wiped data once more after having this problem, still not resolved.

It sounds like you are trying to install Magisk v17.1 like I tried. If so you need to use v17.3 beta. If you follow this thread you should be fine. It even tells you what to do for your original problem, just takes some reading and patience.

December OTA - "Couldn't Install System Update"

I have an unrooted Pixel 3 XL and am unable to install the December update. Each time I try, my phone reboots and sits on the updating screen with the progress bar for several minutes, then reboots and tries again two more times, then finally boots back to the home screen with a notification saying "Couldn't install system update." If I click on this notification I can "Try Again" but it always does the same thing.
Does anyone know what could be causing my phone not to update, or how to look at logs that would tell me what's going on?

I'm just running the regular system update process through Settings > System > Update, so unless my phone got confused about what phone it is I'm not sure how this would happen haha.
The only "non-regular" modification I've made to my phone is that I use Tasker and have granted it several system-level permissions through ADB, but this has never impacted a system update in the past...

I've thought about trying to sideload the OTA, but on the OTA download site the first prerequisite listed is that there are currently no pending system updates, which is clearly not the case for me. Anyone know if there's actually a risk in attempting this?

There is no risk sideloading an OTA via recovery. What do you have to lose?

Well worst case I'd have to wipe and flash factory image, but I really don't want to go through that right now, especially this being the first time I don't have Titanium to restore everything haha

I think you misunderstand. You cannot flash the factory image because you are BL locked. Sideloading an OTA image via recovery is also called a "rescue OTA". Don't worry...your bootloader is locked so you're not going to hose anything. You are stuck now... cannot use system update. Flashing the OTA is not going to wipe your data, or render your phone unbootable. It MAY however get you "unstuck". Just follow Google's detailed instructions on the page you linked. Good luck! :good:

Hmm so it seems I can't even sideload the OTA, I'm guessing cause of the locked bootloader. When I reboot to recovery the screen just says "No command" and no buttons on the phone do anything, I see no option on the phone to sideload via ADB. Running "adb devices" on my connected laptop shows the active device in host mode, but I think it has to be in sideload mode for it to work. I've also tried clearing cache and data from the Google app before trying the regular update method again, but that didn't help either.

1) You do not need an unlocked bootloader to sideload an OTA.
2) Everyone with P2/P3/P4 stock recovery can sideload an OTA via adb. You don't even have to have USB debugging enabled in Developer settings. It is hard coded into recovery.
3) You probably aren't in recovery mode. Youtube a video on how to get into recovery mode, or Google "rescue OTA" or "sideload OTA via adb".
4) Upload a photo of your recovery screen
5) Double check you are using the latest adb/fastboot binaries
6) Report back

You're right on #3, I didn't properly enter recovery mode - after getting to the "No Command" screen I was pressing and holding power and vol+ together (which didn't do anything) instead of holding power and then pressing vol+ to enter the menu. Anyway, once I got in I pressed "Apply update from ADB," confirmed via "adb sideload" that the phone was in the right mode, and started the OTA sideload (see picture for the PowerShell output). Once this completed successfully, I rebooted the phone but it did the same thing as before - 3 bootloops then boot into the home screen with an "update failed" notification.

I would have expected a more verbose output but have not personally had to do a rescue OTA (my phones are all BL unlocked), so I don't know what the correct output looks like... but note there are no errors. Are you positive you are using the latest binaries I linked to? My version is 29.0.5 (October 2019). "adb version"
You stated you were unrooted, but are you BL unlocked? If not, you only have one option left that I am aware of. That is to to a factory data reset from recovery (or settings). If you were to contact Google Support and let them know where you are now and what you have done so far, they are going to have you FDR. The full OTA you flashed via adb is more complete than an incremental OTA and should have corrected your issue. If you are not BL locked yet, but have an unlockable phone you would still have to wipe data during the unlocking process, so go ahead and start backing your stuff up anyway. Good luck! :good:

I have the Verizon variant, so bootloader cannot be unlocked (OEM unlocking is disabled in Developer Options).
adb version shows me:
Android Debug Bridge version 1.0.41
Version 29.0.5-5949299
I think at this point I'm gonna wait for the January update and see if that one takes. Thanks for all the help!

Well, you learned something here anyway. I believe incremental OTA's need to be applied sequentially, but since I always flash the full image I'm admittedly not very versed on OTA's. You may want to research that point further so you don't end up waiting two weeks for naught. Also would not hurt to make sure to manually sync backups, verify photos is backing to the cloud, and in TiBu do a "force redo of your backups" then zip that entire folder, transferring it safely off the phone. Best of luck and Merry Christmas!

Well that's the issue - I don't have the option to use an app like TiBu because I can't have root, so as far as I know I basically have to rely on Google's automatic backups/restores during initial phone setup, if I end up doing a factory reset. Before this phone I've always had a rooted phone with TiBu doing nightly backups to the cloud, so not having that has already been giving me anxiety the entire time I've had this phone haha.
I think the biggest thing I learned is to never buy a Verizon model phone again.

Ah, ok. Well the Google backup has improved dramatically with 9 & 10 and works quite well. Hope you get it sorted soon. :good:
@Jinded, what happens if you try to sideload the OTA for the same version you currently have?
I have been wondering in a different thread, if the Goggle OTAs will work well on Verizon devices. It used to be there were device specific releases on the Google site as well as the general releases. Things like vendor and modem would likely be different.
Edit:
Reading through the forum, this post suggests that settings that are enabled in November are not available in December, preventing the update. Booting to safe mode will probably reset the ROM settings without factory resetting. Less to set back up.
