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. 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
Hi, I wanted to flash the 5.1 update to my new Nexus 6.
I went all over the basic steps.
After I unlocked the bootloader I tried to flash the image with the flash-all command.
It failed, so I remembered maybe I forgot to click on USB debugging? (This confuses me because I think I shouldn't be able to unlock bootloader without this).
When I wanted to start android I locked it first, so I would unlock it afterwards and erase everything to start as new.
Whan I locked it, I could not unlock it again. I can't access Android, neither do anything else like factory reset nor Recovery Mode. I return to the bootloader as soon as I press anything.
There are red words at the top: AP Fastboot Flash Mode (Secure). Does this means anything?
Is there any way to force unlocking the bootloader? When I try it, the phone tells me to go to Developer Options but I can't access Android.
Please HELP! Is there any way to flash a rom or android again in locked state? Recovery?
Thanks for reading this and thinking about a solution! I really hope I won't be stuck forever in bootloader.
Uh oh... Were you trying to downgrade back to LRX22C from LMY47D so that you could upgrade to LMY47M, by any chance?
If so you might be fooked.
Actually no. I was trying to upgrade from 5.01 to 5.1. I'm really scared of having my Nexus 6 bricked. I can't do anything to unlock the bootloader. Maybe I could sideload a recovery? But do I need to be unlocked?

I already tried this solution, I think mine is a little different. At the end of the post it says to enter fastboot and restore with a factory image. I can't because I am not unlocked. In order to unlock my device I have to go to Developer Settings (it is the message when I use the OEM unlock command). but I can't access to Android. I am stuck in the bootloader but can run fastboot commands.

The solution that was posted should work, but you need to use RSD Lite in order to flash the factory image, not fastboot.
Read it over nice and slow again, because you are in panic mode right now, so take your time and you will get it back up and running with no problems.

You should be OK. People in that thread have reported success flashing the new factory image while locked. Check the last few pages of the thread.

Thanks! I've been reading a lot from this thread but I get something unusual as the other people are experiencing. When I try to flash partition gpt.bin I get (bootloader) Unlock before flashin.
It is kind of contradictory as this fix supposedly fixes flashing without unlocking. I don't know if it is a problem of drivers. My PC sees my N6 as Google Nexus Bootlader Interface. In the thread, the PC sees the device as "Bulk" or "Qualcomm ....... etc etc".
My panic mode isn't turning off. I may be missing something.

Now I've tried everything in that thread, when I was reading I thought flashing gpt.bin would be the solution but I can't do it, I can't flash it.. It says "Unlock before flashing". Supposedly flashing gpt.bin would allow me to flash without unlocking.
My last resource is trying this on a mac, I've read you don't need drivers so maybe it is a driver thing. I HOPE SO..

I agree because op is somehow confused.....fastboot has nothing to do with develope settings USB enabled
Yes it does. He flashed the factory images, then relocked (which defaults to disabled oem unlocking). But something failed (guessing possibly userdata failed). I would recommend fastboot formats userdata to perform a factory reset from the boot loader to see if you can get android to boot.

hi, my phone Razr i XT890 is showing the Red Moto Logo, I tried to factory reset by going into fastboot also but nothing happened, I can find many thread here about the same problem but nothing conclusive could be found in those threads, hence I sent my phone for repairs, the technician hooked it up to a computer and said that most likely it is a software issue and the phone would be ok, after waiting for an hour I was told that the emmc has died and it cannot be replaced and the only solution would be to change the motherboard, since the mother board is not avaible in the market I looked it up on aliexpress and it costs around 70$ where as a new/refurbished phones are listed for 75$, need you guys advice on whether it can be repaired or not and if yes then how. I am a regular user and not an expert like you guys so if you suggest any thing plz do it in detail. FYI its a factory unlocked phone which had jelly bean OS and I never rooted it or did any hanky panky to it. Thanks
What u could try to test if the mechanic is right (I suppose he is), is to flash stock firmware by hand and see what the device gives for error.
If the error is an i/o error the emmc is corrupted and we can't help that. It will need a replacement of the motherboard.
To test it, extract all images from the stock firmware. Then flash them while your Phone is in fastboot modes and connected to your pc, like this:
Use a compatible fastboot executable like mfastboot.
- fastboot flash boot boot_signed
- fastboot flash recovery recovery_signed
- fastboot flash system system_signed
- fastboot erase cache
- fastboot erase userdata
Every one of them should return an "OK". If there is an error in one of them that partition is most likely damaged and if u can't boot in recovery there is most likely no turning back.

If it all says OK, u should have a working device. No doubt about that. But if one of them doesn't we found the issue. Most likely i/o. Can u still boot to recovery? Or is that even impossible, because u said u tried a factory reset?

thanks a ton!!!
hi, guys sorry for posting so late, was super busy, any how haven't got a mechanic to flash the phone, guess I will have to do it myself, request you to answer my queries
.1) a mechanic to whom I went convinced me to believe that the problem was due to a faulty battery and he could fix it in 5 mins flat, He opened the phone did some tinkering with it, I am not sure what but the phone was in same condition ie Red logo on booting. Was very disappointed came back home and I tried to restore it through fast boot and I noticed that the Battery Current was coming as 4.1 V earlier it was 3.7 !!! I am sure that the mechanic messed it up. Now my question is will it harm the phone, battery or any other part?? Should I just leave it the way it is ie 4.1V and not try to rectify it to bring it to 3.7V.
.2) I am not able to get a mechanic who can flash the phone as suggested in previous posts, pl tell how I can do it myself, I am a newbie at this and have zero knowledge of the process, pl tell what all software are needed! And hardware if any. All I have got currently is the firmware posted in previous posts.
Thanks
I need to lock my bootloader to do an exchange at T-Mobile. I have 20R stock flashed, but it still says custom bootloader upon boot, how do I relock it safely?
I read that "fastboot oem lock" will work, but will brick it if I don't do it perfectly. Any advice on what to do?

I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in

adb devicecs
- you should see the phone listed as one of the devices in the command line window

adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top

I'm terribly sorry if bumping is not ok.
Thought it wasn't worth making a new thread, since my post is about the one above.
Has anybody actually tried these steps above? (Since every other thread mentioning this says it's a one-way only thing..)
Does locking the bootloader means also loosing the custom recovery? (I'd expect that, but asking to be sure)
Does it return the phone to it's original state? (ie. before one unlocked the bootloader, or there are some differences?)
Does it also means I would be able to get official OTA updates and so on? (since with a custom recovery, that's not possible)
Thanks in advance.
Yes, it does work. I did it, worked perfectly. Yes it does return your device to it's original state. Just make sure the stock ROM is flashed and all should be well. I didn't try, but I see no reason why it wouldn't let you get OTA updates from T-Mobile. Let me know if you need help.

i think you loose the twrp phone doesnt show unlocked bootloader message did not check recovery but it must revert t stock one.. not sure about OTA since am not in tmobile network.
you dont need OTA. you can always download KDZ and flash it with LGUP.

My H811 T-mobile phone needs service. It has original 20v software version. It is unlocked with TWRP and rooted. Can I use this method? Do I first have to downgrade software to some other version? Will this method also take out TWRP and root or do I still have to take them out before doing this? How? Please help.

no need to downgrade. to remove root and any trace if phone works. is to use KDZ then once it boots into system do the lock procedure. so it locks and the small white letter are removed. this way its like stock rom and recovery and the above commmands will make bootloader locked. and sent to repair. if bootloops try the freezing method.
Used on an LG Aristo that has Cyanogen and it worked

ive said ive done it. on the above instructions you dont beleive.??
i think you loose the twrp phone doesnt show unlocked bootloader message did not check recovery but it must revert t stock one.. not sure about OTA since am not in tmobile network.
you dont need OTA. you can always download KDZ and flash it with LGUP.
and stay uptodate.

This was the only one i found that didnt brick my phone and trust me ive bricked and unbricked this phone many times
When you use the fastboot command to lock back your bootloader, the phone doesn't revert automatically to the stock recovery and actually that is partly the reason why it bricks and other main reason is that changes made to bootloader to obtain root brick the phone. before you relock bootloader, if you have SuperSU (in-app menu option) or Magisk (uninstall zip file), use their respective methods to unroot the phone, then use twrp to flash .image file of stock recovery to recovery partition then use the fastboot command to lock the bootloader. Even then it may or may not work because if whatever method the phone uses to check the integrity of bootloader and/or recovery, such as md5, if it doesn't match, the phone will still brick. Since all your data on phone will be erased regardless as soon as you lock the bootloader, i personally just fastboot lock the bootloader, remove battery to power down, use the volume up and plug usb cable in from pc to put phone in download mode and just use LGUP (uppercut) if have kdz file already, which i do, i just let LG Bridge download the file, find it in programs folder and copy it to another location before LG Bridge deletes it --OR-- just use error recovery option in Software Update tab in LG Bridge as both LGUP and LG Bridge will detect the phone in download mode even if it is bricked.
By the way, I have used both methods above dozens of times without any issues, someone above who mentioned phone boot-looping because of locking the bootloader, it is boot-looping not because of hardware flaw which was widespread in LG G3 but a software issue (phone boots up, doesn't find the software configuration it is looking for and just restarts) and they are not the same issues, no need to freeze the phone, won't help.
the method works, but no OTA from T-Mobile. "verification problem".
When I try to "adb reboot bootloader" I get "security error".
If I try reboot recovery, TWRP is definitely not there.
Just want to update from20Q to 20X.
Any help would be appreciated.

The above points to you not giving permission possibly because either you missed the permission pop-up or selected option that didn't allow permission.
Can anyone help me?

managed to solve?
...and I thought it had worked but as it turns out, it did not. I found out it did not when I tried to root to which the phone proceeded to tell me it was lock.
Now, when I go into Recovery Mode, the phone does not come up in ADB even when trying to unlock after using the ASUS unlocker tool... Is the ADB bridge fried forever? How do I reinstate it to be able to root? I don't mind wiping, I just want to recover the possibility to root. Any way to do that? God I feel dumb right now...
Edit: I've gotten ADB to recognize the phone in Recovery Mode by installing the exact Manufacturer and Model ADB drivers but the second I get into Fastboot mode, it's like the side USB-C suddenly becomes non-existent, same goes for the bottom one. Feels like a kill.switch from ASUS to me :/
Edit 2: Is there a way to flash while in Recovery? Or in normal OS operations? (sounds like a bad idea but I'm out of ideas as of now)
So neither of the two USB ports in the phone seem to work for you in bootloader mode?

Exactly, the bootloader is also unlocked after using ASUS's tool .apk, I am on 1910.44 WW, I tried different ADB's while in Windows, tried to copy DeviceID, it all works when in normal boot OR in recovery mode but the second I am in fastboot mode, both USB's stop working. As if ASUS locked the access when I mistakenly tried to gain root while the bootloader was locked. Maybe if I could lock it back but that would require me being in fastboot afaik.
Can I lock it back while in recovery? If so, what would be the prompt?
I would be very careful about locking the bootloader at this point. I heard it can cause a brick if the planets aren't aligned correctly.
Jokes aside, does device manager refresh itself when you plug or unplug the phone in fastboot mode? That would indicate it saw something from the phone.

Sadly no, tried 3 different computers, a plethora of cables, different USB ports. It's like the Fastboot killed the function altogether so as of now, I have yet to find a way to get the phone recognized while in fastboot.

Is there an option to apply a full OTA from the stock recovery?

Before anything, thanks for helping, it's greatly appreciated!
So, no sadly, when I get in Recovery Mode my options are:
Reboot system now
Reboot to bootloader
Wipe data/factory reset
Power off
As anyone would, I tried kicking into bootloader from recovery hoping that it would trigger something different to give me fastboot but to no avail, I wiped a couple of times as well, that didn't pan out.
Edit: I feel like my best chance at this point is when ASUS releases a new WW firmware update, that it HOPEFULLY brings Fastboot Mode to it's original value... But according to a thread somewhere on XDA, it does not install a full partitioned recovery so I'm not having my hopes up...
The other thing would be to butcher a USB-C cable and see if I get a response when connected on the orange USB-C but that's also a risk to take. So that doesn't work, that USB-C gets no response whatsoever.
What firmware version are you on? You could try grabbing the stock firmware zip of the firmware you're on now from https://www.asus.com/Phone/ROG-Phone-II/HelpDesk_Download/, and increase the firmware version in the zip name - for example, if you're on the latest .44 build now, change the .44 in the zip name to .45. Then simply push it to the root of your internal storage, and reboot. After boot you should get a message that a system update file has been found, and that you can install it.
I don't know if this will fix your problem, but it should reflash the stock partitions. And yes, it's true that it far from flashes all partitions, but it's worth a try at least.

I did put the stock firmware but I hadn't thought of changing the name to "force" the phone to try and update! Sadly, when it reached 100%, it said install failed and while trying fastboot mode, it still didn't restore ADB but that was brilliant and definitely worth the try. Thanks for your suggestion, here's hoping the next legit firmware will do it!
EDIT: AND YET IT DID WORK!!! That must have fixed it after all... I unplugged, replugged while in bootloader and finally, that USB chime! T-T
Thanks both of you for your suggestions, 3 brains work better than one!

Nice, glad to see it worked! I tried it myself and it also said update failed, but it had flashed, so I think the error message may just be because the firmware version doesn't change.
I'm assuming fastboot works now then? Do keep in mind that you'll need the abl, xbl and xbl_config images from the edl unlock thread to be able to actually unlock the bootloader without using the Asus tool.

Yeah it works, or at least it did long enough for me to be able to root. I haven't tried it since but I would assume that it fixed it, tomorrow I'll most likely do a RAW flash to fix all potential risks as well as try the latest CN firmware. EDL never worked, that's what got me in that situation in the first place... well that and me not paying full attention.
