Hey all. I'm coming back from a custom ROM/kernel and I've successfully flashed the latest factory image. However, fastboot is spitting out an error when I go to relock the bootloader. Here's the output:
C:\Users\***>fastboot flashing lock
...
OKAY [ 0.002s]
finished. total time: 0.003s
After I issue the command my N6's screen goes unresponsive for a few minutes, after which I can still use the volume keys to navigate the bootloader. However, after a reboot, the device is still unlocked.
Has anyone else encountered this issue?
Try using "fastboot OEM lock". Fastboot flashing lock is only for the 5X/6P from what I understand.

I don't know why it refuses to relock but another question: why do you want it to be relocked? It is adviced to only relock a bootloader when it is absolutely needed (warranty case, resale...)

This did the trick. I'm not sure why I didn't just try the old command myself before asking. Thanks!
Hi,
I am unable to unlock the bootloader on my Nexus 6, which was purchased new from Amazon.com. Or more accurately, I can issue the fastboot flashing unlock command without error, but my phone still says LOCKED and screen is frozen for 60 seconds.
I have followed the various HOWTOs on this website to the best of my ability:
1. Installed latest Android SDK tools(25.1.4.rc1), Platform-tools (24rc2) & Java8. I originally installed with the 23.1 platform-tools but then moved to the preview channel release when I had no luck.
2. USB debugging and OEM unlocking are both ON
3. Both "adb device" and "fastboot device" show my phone's serial number when in their respective modes, so I know communication is good between my laptop and phone.
How to replicate problem:
a. With my phone connected, I first issued "adb reboot bootloader". My phone then sucessfully changes to the AP Fastboot Flash Mode (Secure) screen. Beneath the green BATTERY OK (Charging) are the lines
Device is LOCKED. Status Code: 2
Transfer Mode: USB Connected
b. I then type "fastboot flashing unlock" and the output is
...
OKAY [ 0.016s]
finished. total time: 0.016s
However my phone does not ask me if I want to unlock. In fact, the screen then appears to be frozen -- pressing the volume up and down buttons does not change the power button selection menu. If I try to issue any other fastboot command, it says FAILED (command write failed (Unknown error)) finished. total time: 5.017s
The screen is frozen for 60 seconds. After that, the bootloader screen is once again functional (I can change menu options again) and I can issue new fastboot commands, such as 'fastboot reboot'
However, the device still says LOCKED and will refreeze for 60 seconds if I type 'fastboot flashing unlock'
Any suggestions would be appreciated!
Thank you.
type fastboot oem unlock to unlock your bootloader, then follow instruction. But beware, this will wipe your device

In newer versions of fastboot, the command is fastboot flashing unlock, not OEM unlock.
Code:
$ ./fastboot
usage: fastboot [ <option> ] <command>
commands:
update <filename> Reflash device from update.zip.
flashall Flash boot, system, vendor, and --
if found -- recovery.
flash <partition> [ <filename> ] Write a file to a flash partition.
flashing lock Locks the device. Prevents flashing.
flashing unlock Unlocks the device. Allows flashing
any partition except
bootloader-related partitions.

No, I had not. I tried using fastboot oem unlock on an older version of the SDK toolkit and that had failed, but I had not tried using oem unlock again on the latest version, having noticed that "oem unlock" was no longer listed as an option.
I just tried it now on the latest SDK toolkit and it does indeed work for me. :good:
Thank you to the both of you for helping me out!

Welcome
i do believe the "fastboot flashing unlock" is for when a manufacture issues a binary token kinda of like how HTC does it. If the Nexus or any phone that is not carrier branded, "fastboot oem unlock" will be the command to pass.
Oem unlock Blackview BV6000
I go to settings "settings" -> "Developer Option" -> "Oem unlock" -> Enabe

@blu3m3,
when it asks to press volume up, just press it and in a few seconds bootloader will get unlocked
But don't forget to type the command 'fastboot format userdata ' & hot enter after unlocking bootloader.
And one more thing, just don't worry about that OEM unlock option in dev settings, it does nothing

That's what i do too,
I enabled in Developer Options OEM unlocking
I done what you told me , but still not working
I pressed up and waited about 2 minutes pressed.
I think bootloader must be locked something else, but i don't know how.

check if your phone's drivers are installed correctly and whether your phones is recognised in fastboot mode or not.
you can check it by typing "fastboot devices" and enter.
If it shows something like device serial name or anything, then your device is connected in fastboot mode otherwise install correct drivers.
Hope this helps.

wait! wait!, if you wanna flash a ROM after unlocking bootloader, then you can do that without unlocking it too. Follow the steps.
1). Download flashable twrp zip by 1cefire and put it in your sdcard and also extract recovery.IMG from it.
2). Put that recovery image into the folder where you have your fastboot and adb files.
3). Reboot to fastboot and type
"fastboot boot recovery.img"
after that phone will temporarily boot into TWRP. Now just flash the flashable zip of TWRP from yr sdcard to permanently install TWRP recovery.
Hurray, now you can flash any ROM without unlocking bootloader.
Press thanks if it helps.

them you should try flashing the same recovery.img with SP FLASH TOOL. Just replace stock recovery with this one and uncheck all other options except recovery while downloading through SPFT.

Nobody has anything new to unlock the bootloader ?
Hello friends,
I'm have made a "Flashing guide" to update your Blackview BV6000's ROM to Nougat 7.0.
Please follow the link below and update ROM. You could also find a "TWRP installation + Rooting Guide" for your Blackview BV6000 in the archives.
http://dreamworks75.blogspot.in/2017/08/rom-flashing-guide-blackview-bv6000.html
Happy Flashing !!
+1 on this one.
I'm too stuck on that disabled volume up button, when confirming whether to oem unlock the phone.
I've read in a blog post (can't link yet) that one can specify a 16-digit unlock code for the fastboot oem unlock command, but I have no idea whether it would allow me to confirm unlocking - and also no clue where that code could be obtained from in the first place.
So, any further info?
Hi!
I'm trying to install TWRP on my P10. I've unlocked bootloader on Huawei website.
Whenever I'm typing in fastboot "flash recovery twrp.img" it goes through and everything says OK
But when i try to "fastboot boot twrp.img" I get FAILED (remote: command not allowed)
"fastboot oem device-info" gives me the same error too and "fastboot oem unlock" gives me already fastboot unlocked
What do you thing "fastboot boot twrp.img" should do? This command isn't allowed because it does not exist.
If you want to boot into your flashed TWRP recovery, you have to enter "fastboot reboot" and press volume up while booting - the USB cable has to be disconnected.
Instead of "fastboot oem device-info" try "fastboot Gevtvar unlocked".
or use adb when the phone is running.
"adb reboot recovery"
you can't go direct from fastboot to recovery simply by a command
Yeah, the command was wrong, sorry xD
Anyway I thinks it's fixed now and I'm able to boot manually to recovery from phone now!
jejeje i was coming here to tell you about wrong command
I have the same problem with FAILED (remote: command not allowed). When I try to install or flash anything I see the info about FAILED (remote: command not allowed). I have FRP locked and I can't enable OEM developing option (it is inactive). I can't relock bootloader, can't instal TWRP, I have only simply erocevery where I can't wipe - only reboot and shutdown device.
I tried do update via dload, hwota - all with defeat
In ADB and Fastboot I can see my device connected.
Does anyone have any idea?
do you have instaled driver for P10, does computer recognice device like P10 ?

Any news? My p10+ it's in the same case
same problem im already unlock but the twr not install what is propper command
Hey guys, for all of you with "command not allowed" problem, you have to check OEM unlock setting on developer options but if you have a greyed out button, you need to flash again your stock room with a tool like dc-phoenix unlocker and bypass frp lock (on YouTube you will find tons of videos regarding this matter). Also, you can check if your Fastboot is protected (frp locked) on Fastboot screen...
There you go---> https://forum.xda-developers.com/hu...ution-bl-unlockedfrp-locked-fastboot-t3684302
PS READ the post to the END!! don't make mistakes it's really easy and fast. It works!
Hi guys.
I know this thread is pretty old but I'm getting the exact same problem as the OP except on my P20 Pro: I can flash a recovery but not boot one from fastboot.
The biggest difference is that my bootloader is unlocked and I have FRP Unlock, so according to every post I've seen it SHOULD be working.
My fastboot log:
PS C:\adb> fastboot devices
LCL0218415002142 fastboot
PS C:\adb> fastboot boot twrp-3.2.1-0-charlotte.img
downloading 'boot.img'...

Have you try this command fasboot reboot recovery_ramdisk?
I get:
PS C:\adb> fastboot reboot recovery_ramdisk
fastboot: usage: unknown reboot target recovery_ramdisk
with "fastboot boot recovery_ramdisk" I get
error: cannot load 'recovery_ramdisk': No such file or directory
I sorted out my problem from a different angle so I no longer need to boot to TWRP from fastboot. Thanks for your help!

This was quite some time back so I don't remember all that well, but I think I just used the built in Huawei recovery, erecovery, to restore my whole phone and then I was able to reinstall my custom recovery and boot to it normally. I can't guarantee this as I don't remember the whole context of this. Using erecovery I didn't lose my locally stored files, only my apps and app data. Hope this helps.
what I have done is this:
Rooted phone
Installed TWRP
than I updated (stupid)
Lost root than I wanted to install Custom frimware what didnt work
Factory resetted phone, phone doesnt boot anymore now.
I can only access fastboot but I can not get fastboot to work on pc installed many different drivers just dont work.

Every two or three days people report here they bricked phones by forcing update or Factory reset (or relocking Bootloader) from custom or rooted phones (or by having TWRP) - one must first go back to the original stock firmware he had, before upgrading/resetting/relocking...
And this thread will also not help to somebody else -
since 'somebody' will not read (before bricking the phone) ;(

Do you still have TWRP - use HWOTA to flash stock
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
If you have no TWRP but Fastboot is showing Bootloader unlocked, you should be able to flash TWRP.
If Fastboot is showing Bootloader locked but FRP unlocked, you should be able to unlock Bootloader.
But if there is no more TWRP and Fastboot is showing FRP and Bootloader locked - maybe DC Phoenix can help you
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
I used this command in fastboot: fastboot oem device-info
But I get this error: FAILED (remote: Command not allowed)
On my phone it says: Phone: unlocked and FRP: Lock

Yeah, this is not adb/fastboot drivers problem but a fact that you either did not keep OEM Unlocking or it locked due to your procedures. But you have no system to boot in and to unlock.
Is TWRP still on? Press and keep pressing Power until phone shuts down (from Fastboot).
Try to boot to recovery by keeping pressed Vol + and Power -- if it boots to TWRP proceed by HWOTA as above.
If it boots to eRecovery instead, maybe you can try Factory reset (although, I don't believe it will work)
If you don't have recovery anymore (and you have no system and FRP is locked) then you really bricked the phone, you should pay for DC Phoenix and try to unbrick

Can you enable Developer options - then why cannot you enable USB debugging?!
You must first enable Allow ADB debugging in charge... and only then USB debugging -otherwise USB debugging switches off

So I got my phone to boot but everytime I want to do something in recovery or something else It wont boot anymore and than I need to make the battery run out of juice. are there anyfix without needing root recovery or fastboot.
ADB wont work because usb debugging wont turn on (tried many things), Fastboot kinda works but gives the error (remote command not allowed)
Cannot get into any Recovery I can boot to OS
