yes the bootloader is unloack but i had my phone rooted before then had to use pc companion to repair it, ive unlocked it again to be sure.
It seems driver problem.
I met the same problem as well as others yesterday, when I unlock, relock, re-unlock, root locked, root unlocked, flash recovery... for some crazy reason.
Try these:
Connect to flashtool (beta2 or beta4) with device power-on debug off, to see if flashtool can recognize it, and how much it can recognize.
Connect to flashtool with device power-on debug on , to see if flashtool can recognize it.
Connect to flashtool with device in fastboot mode, to see if flashtool can recognize it.
Connect to flashtool with device in flashmode, to see if flashtool can recognize it.
Flashtool may fix some driver error. I just succeeded after hours of bungling like that.
Good luck.

Plz Help
same issue...
Has anyone found a sure fix for the issue presented by the original post? I am having this issue and I have tried different drivers, ftf's, computers, adb/fastboot/versions and flashtool versions. I have unlocked and relocked. Is rooting status "unknown" normal after bootloader unlock? -Z Ultra 6833 EU
Still no solution?
With my C6603 it does not allow to write boot aswell. Any final solutions?
edit: solution found: bootloader was not unlocked

This is the wrong forum to ask this. This is the Xperia Z section.
Despite that, you need to unlock your bootloader to flash kernels via fastboot.

After months using stock everything I decided to flash CM11 yesterday, I'm doing exactly same step as I was doing when on 4.1/4.2 but it seems like it doesn't works, I'm not even sure that my BL is unlocked despite success message, when trying to reboot after unlock BL I had a bootloop and when trying to recover with Sony's Flashtool it says 'device not unlocked'. So I repaired with PCC and restarted from scratch but same results today.
I'm totally lost as like I said I was doing exactly same thing on the same PC.
Edit : Now my XZ doesn't even start! I have the red led blinking while connected with usb, power+ Vol+ doesn't do anything, no vibrations at all!
I was on latest sony official ROM
Edit2 : Tryied again to recover with Sony's Flashtool but it says "Mobile Locked" that's crazy!

fastboot remote command not allowed Xperia Z3
I unlocked my boatloader, but have no way to confirm that it is still unlocked. I'm running Windows 7. Fastboot used to work just fine before I unlocked my bootloader. FLASHTOOL works fine. But if I try to flash anything with fastboot I get the remote command error. Can't flash recovery. Can't flash boot image.

Look in the service menu to confirm if your bootloader is unlocked.
Enter *#*#7378423#*#* in the dialler, then look in Service info -> Configuration. It will say "Bootloader unlocked: Yes" if it's unlocked.

By installing FLASHTOOL by Sony I was instantly notified that my bootloader was not unlocked, even though I had already unlocked it three or four times without any errors. So I unlocked it again. Then fastboot flashed my images just fine.
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?

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.

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.

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.

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

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?

Hi guys,
Accidentally, im locked the bootloader of my moto z3 play and i cant boot because a previous bad installation that results in a bootloop.
I cant unlock from fastboot because the acctual system is new but unbootable (usb debugging and oem unlock disable by default...
I saw that there is some toolkits for many brands and models to fix this...
Will there be any for moto z3 play? or any other way to fix this brick?
I can access fastboot and stock recovery... Can i flash anything from adb sideload?
ty in advance

You should be able to reflash the firmware
Use
Code:
fastboot getvar all
To get the codename and software channel

I forgot to say that i ran by mistake flashing lock command, in way that oem is lock AND flashing too.
I have tried many times flash stock 9.0 firmware, but most part of lines out are permission denied (cause of flashing locked, i guess...)
After try flash, i get only bootloop and stock recovery.
I even already try apply update from adb sideloa to twrp or cwm but doesnt work (((
Plus, i try TOO boot on edl mode to use blank flash but doenst work, going to fastboot reason qcom boot failed ! ((((((((
I suppose can reflash the firmware with flashing locked? I have tried one of these beckham 9.0... I confess that not tried all of them.
Ty, man, for help!

Unlocking your Bootloader, you know where you enter that long code from the email that Motorola sent you.
I say this because sometimes people think, unlocking in the Dev-options, is actually unlocking the BL, when it's not.
Nor is a carrier unlock the same thing.
Your bootloader sounds locked from your Description of "access denied" errors.
I just want you to clearify that you are actually unlocked.

Yeah, i have the code from motorola and i try unlock with "fastboot oem unlock code", but:
(bootloader) Check 'OEM unlocking' in Android Settings > Developer
But, as i said, i cant boot o.s. to active oem unlocking.

Although you're on Z3, this problem is generic. Ask in the Z2 forum, as they are more active. I also think the G-series (or other popular Moto phones) forums could help you with this.
Can you get to the recovery menu, and wipe factory reset (BL->recovery, up+pwr, Wipe/Factory restore)?
?

Ty for the advice... I will do that.
Yea, i can wipe data/factory reset, but its the same. Bootloop until stuck to "fastboot reason: fall-through from normal boot mode."
I've read about this scenario for months on several different model forums and I imagine my best chance is to use the blankflash in edl mode but i can't boot into edl mode. Wherever I connect it is always recognized as a Motorola PCS or Motorola ADB device. I'm thinking of buying the deep flash cable and see if it works ...
$ fastboot getvar current-slot
//Getting and setting the slot should not cause any harm, but you never know.
$ fastboot --set-active=<a/b - whichever "current-slot" isn't.>
$ fastboot reboot
EDIT0:
In addition, you should plan ahead if you do get in. Like doing everything it takes to allow you to unlock/flash (adb).
You don't want to miss anything critical and screw up that other slot too.

To everyone who is having this problem, just run the command multiple times in a row and it works! I don't know why, but just running it a few times in a row (I had to do like 9 times) gave me the unlock code.
Same thing for applying the code after getting it from Moto. Had to do it like 9 times in a row again, but it worked.
