*HELP!!* locked bootloader with no OS

So here's my problem...
I've accidentally wiped out entire phone (including OS)...
I still have access to TWRP, but the bootloader is locked, meaning I cannot flash stock rom (or any roms) to my phone...
I've tried to use following command:
fastboot oem unlock​but it gives me this:
<bootloader> Check 'Allow OEM Unlock' in Developer Options.​FAILED <remote failure>​
How can I check 'Allow OEM unlock' if I can't even get to the setting..?
I see others have similar issue like me but there's no solution to be found... Anyone know how to fix this problem??

Boot into TWRP. Connect to PC. Download a ROM to your PC. Drag and drop the ROM into your internal storage. Flash ROM with TWRP. Enable oem unlock via developer options. Boot to bootloader. Fastboot oem unlock.

^ this. You'll still be able to flash a rom because you have twrp.

Are you trying to flash a factory image through TWRP? That won't work. Download a ROM (other than M preview) from the Android development section. Any custom ROM other than M.

To get him up and running with a locked bootloader, I chose to keep it simple. M would require the bootloader and radio flash and that's not happening with a locked bootloader.

doesnt require the radio flash, but does require the bootloader flash. I did forget though, you're right. I updated that via twrp as well. but you are very right about keeping it simple

i got excited when i found this thread. then I realized I have no recovery. this phone is seriously screwed it isn't showing any screens or anything

So i did this.I did a force update to B609,then i did a local update to B621.Next i installed TWRP and flash Super SU.I tryed to install BusyBox from Playstore but when i tap "install" there is an error,so i flash it with TWRP.So i open the program "P7-Easy_Update_and_Adjust" but it said "Wait for device..." so i installed terminal emulatore and typed:
su
mount -o rw,remount /system
cd system
lsattr
chattr -R -i *
rm –f /system/set_immutable.list
lsattr
The file is eliminated but after reboot is again here,again!

Guys, believe me, "Phone unlocked" in fastboot mode doesn't mean that it's really so.
@Jt1995, Execute following in terminal emulator:
Code:
su
cat /proc/cmdline > /sdcard/cmdline.txt
Then take cmdline.txt from your internal storage and put its content here.

So i must contact huawei for having to code to unlock bootloader?

Obviously

No...
You have to downgrade your phone to b133 or another emui 2.3 Rom.
Than use rootgenius and root your phone. After that you have an realy unlocked bootloader.
And after this you can update to the Rom of your chooise.
My tool easy update and adjust cant delete a file without busybox or full filesystem rights. I know that the error messages are ****. But its only a tool for fast flashing. I kept everything reenter any loss of hand.

Just flash kernel unlocked. as i was said go back. if possible to the lower version or EMUI 2.3. there many kernel version totally unlocked. you don't need to contact huawei coz your phone bootloader is already unlocked.

Flash TWRP using Wugfresh on Nexus 6 w/ N

I've been trying to flash the latest TWRP recovery on my N6 using Wugfresh NRT. I am currently running Android N DP3. I go the advanced utilities and Recovery under Fastboot Flash. NRT goes through the whole process of flashing TWRP and the perm-recovery-signed.zip then reboots back to normal. When I try to reboot into recovery it always goes to the android on his back with a red exclamation and says No command. I've tried rebooting into recovery using NRT and trying from the bootloader, neither works. Any ideas?

Toolkits are stupid ESPECIALLY on a glorious Nexus device.
-Make sure you have OEM Unlocking enabled under developer options
-Boot into bootloader. When the phone is powered off, hold power, volume up and volume down simultaneously.
-Download the latest TWRP from here (at the time of this writing is
twrp-3.0.2-0-shamu.img)
-If you don't already have ADB and Fastboot from the Android SDK install this: [TOOL]Minimal ADB and Fastboot [4-27-16]
-Move the TWRP file you downloaded into the same directory where you installed ADB and Fastboot
-Open a command prompt window in this same directory and run the these two commands (first one might be unnecessary): "fastboot oem unlock" and then "fastboot flash recovery twrp-3.0.2-0-shamu.img" with no quotes
-Reboot into recovery, and voila, you have the latest TWRP booting on your device.

Stock Recovery: Lenovo K4 Note 6.0

Lenovo K4 Note: Rooted
Recovery: TWRP 3.0.2
Android Version: 6.0
Stock Rom
a7010a48_s219_160810_row
I want to encrypt my phone, but when I do it nothing happens. Screen goes black, I waited for 5hrs .. still black screen.
I rebooted normally & saw in settings that device is not encrypted.
I am guessing this is happening because of TWRP.
Can anyone please upload stock recovery for above mentioned Android version?
Thank You.

Bro, just ask him to unzip "recovery.zip" and then use the "recovery.img" for flashing!
