You made a mistake there as you have to enter "adb reboot bootloader" instead of fastboot. Other than that, it works perfectly. Thank you.

I can't get my bootloader locked. Under dev options, "OEM Unlocking" it grayed out.

Did you find a solution to this? I'm running into the same problem with OEM unlocking being grayed out. I returned to stock just fine, but my problem is booting into the bootloader. Every time I try, it just goes to the "your device cannot be checked for corruption and will reboot in 5 seconds" screen. During this screen and during the screen that comes up you press the volume keys for the options menu, the fastboot oem lock command does not seem to work. Fastboot devices doesn't show any devices listed either

Seconded, I'm having the very same problem. Strange thing is, I cannot boot into booloader. I can boot into recovery, I can boot to system but whan I try to boot into bootloader via adb reboot bootloader, the phone just boots into system. If I try Power/Vol-Down, I will eventually land in FTM mode.
Anybody any clue?
SOLVED: After using the Windows based Axon7Toolkit which used Miflash to restore fastboot, I was able to boot into bootloader and also re-lock it.

You couldn't boot into bootloader because there was no bootloader mode. As soon as you update to a recent Nougat build (or an upcoming one) via official zips, your aboot.img will be changed and you won't have bootloader mode anymore. Axon7toolkit relies on fastboot, so it flashes a package through MiFlash that gets you fastboot support.
Jus sayin

Thanks for the clarification.
Is there an aboot.img I can flash e.g. via axon7tool so I can enable fastboot again?
Would that be counted as a warranty void by ZTE?

You can use the A2017U_FASTBOOT_UNLOCK_EDL from 4pda guys with MiFlash. Doesn't matter if you have a G, use this one
Actually axon7toolkit seems to flash that every time it does something related to fastboot. And after you lock it, you can install an official update zip (the latest one for example) and you'll get your phone totally stock, bootloader mode will be blocked.

P9 Lite Bricked. Help me!!!

Hello,
I was always a Samsung fanboy, but than I decided to buy the P9 lite (VNS-L21 single sim)
I wanted to flash the android 7 update for my phone, but I was such a noob in Huawei, that I didn't understand a word. But i tried to do what the instructions said. Now my phone is bricked. I can go to recovery, erecovery (which can't download anyithing) and download mode. I heard of this fastboot stuff as well, but I don't know how to do this. I tried to flash as many roms as I could with dload and it didn't work, after 5%, it said it failed... Now I don't know what to do. I think somebody (expert) should make a clear tutorial for noobs. Oh and I almost forgot that i don't have root, custom recovery, and things like that. I just bought the phone, I didn't want to make big changes, just new android. Is it possible that after this Huawei would fix my phone, if I couldn't? Or warranty is void? And sadly I don't know more of my phone because I'm not ina rom, and the phone and papers don't say more.
If you could help me, I would appreciate it:
Raul

Turn off your phone, connect to the pc while holding the volume down button, you will end up in fastboot mode.
I assume you have ADB and drivers installed (if not, install ADB and device drivers).
Optional: unlock your bootloader if it's locked.
Download the latest offical rom zip for your phone version (the marshmallow one), extract the update.app.
Use Huawei extractor to ectract the following files (google is your friend in this one, but its not difficult):
boot.img
recovery.img
cust.img
system.img
After you've done this, connect your phone to the PC in fastboot mode .
Open a command promt from the folder where the extracted files are (shift+right click, Open Command window here), enter the following commands
fastboot devices (you will see the list of attached devices with a lot of random number + fastboot)
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
fastboot reboot
After all this, you should be good to go, just be sure you are using the correct rom for you version.
Or you can just serach on the forum and find this.

Post here IMEI and SN from the box of phone and i can try get your bootloader unlock code...

If I would unlock it, would fastboot work? Because fastboot pc app recognizes my phone, but my phone says in fastboot mode, that I should connect itself to pc and open hisuite. WTF?

Until you have bootloader unlock you can not run any fastboot flash command...

What is the error? - Have u disconnected the device from the PC during the update?
If not, try to update again and just disconnect the device from any USB connection...

Hello. I disconnected it from everything (for example USB)When I tried to install it said something like incompatibility version, but it couldn't be because I tried many roms for my phone. And I tried some dual sim roms as well because, I thought that it might work... But then I will do that unlock if it will do good. Thanks for the help Without bootloader I can't flash from dload as well?

Heyho,
the dload method works always without unlock bootloader. But, u can't flash for example an B161 over an B3xx (what nougat is) if the update u installed modified already the oeminfo u are not able to flash any rom below B3xx (nougat) via dload.
-
In that case u might use the official rollback package (never tested it myself) or, u unlock ur bootloader, flash a TWRP recovery matching to ur current FW. Flash from there a oeminfo + custom.bin (lower than B3xx) and flash the FW matching to the new oeminfo via dload and stock recovery.
Regards,
Sebastian

If you have custom recovery, wipe everything. Data, system, boot. extract update app (which is your stock rom) with huawei update extractor. go to custom recovery, flash stock boot IMG and stock recovery IMG. Power off, use three button dload method, reboot, when booting press vol up for three second, now you are in e-recovery. Press shutdown. Press and hold power and vol up for stock recovery. Do factory reset. If need do the factory reset 2/3 times. Now you are with locked bootloader.

Huawei P10 Lite - Bricked Device

Hello everyone.
I Have Huawei P10 Lite WAS-LX1A and I accidentally bricked my device.
I was using TWRP to install a rom, and I wipped my system but the rom couldn't be installed for some reason. So I thought my TWRP Version had a problem, so I tried with bootloader to istall a new TWRP.
In adb I pressed:
fastboot flash recovery TWRP_by_GreatSlon.img
Click to expand...
Click to collapse
and then
fastboot flash recovery custom_boot_decryptdata_b130
Click to expand...
Click to collapse
But now, it doesn't load TWRP at all when I press vulume up + power button. I am stuck with out TWRP and with out an OS.
And I can't enter bootloader to install a new TWRP. Is there anything I can do?
I do have a laptop and an SD Card and my Bootloader is unlocked. Phone Unlocked and FRP Unlock are red, so maybe there is a way to save my phone please? I need help please . Sorry if I am not explaining very good and if I don't write correctly, I'ts because I am very very sad . Please someone tell me there is a way to fix it. Maybe dload? But I cannot find any file that it fits.. Thanks in advance.

I found this youtu.be/pkWSDlrLmns and I intalled a new TWRP. But I still cannot find any ROM to install. Any help please?

you flashed twrp in recovery partition and after that, you flashed "custom_boot_decryptdata" also in recovery partition. so, twrp was overwritten. that's the reason why it doesn't work now. are you able to enter fastboot? (VOL- & power button)?
are you on emui5 or emui8?
if you can enter fastboot mode, flash twrp again.

Try to flash all partitions from a service rom.

I have the Same Problem. Only dark screen with fastboot connection.

(Sorry for the very late reply) I could enter fastboot using a pc, and then flashed a different twrp and costum rom.
Everything was okay. But, lately my rom started having network problems and I decided to flash an another rom..
But when I did, something wrong happened and now I am without twrp, without rom and with phone and frp locked.
My destiny is to brick my device and go to imposimple position, isn't it? I don't have my unlocked code so I cannot unlock my bootloader. I paid and tried dc unlocker to unlock my phone, but after plug-unplug it stopped being unlocked again and my money for dc unlocker gone for nothing and I am not willing to pay again for something like that. Any ideas to unlock my phone?
I sent an email and message to Huawei to see if they can give me the code, but idk if they will do. Any suggestions?

This post can be locked. This thread continues here. As for the Huawei, they respond that they don't give the unlock code anymore..

Ok thanks I will send it in to a shop where someone can do that

Connect phone to pc, start adb on pc...put phone in fastboot mode ( press volume - and power ) , type in adb
fastboot continue
After command, phone will reboot and boot system.
After that , you add mi acc and start unlock process.
If you reboot phone, you need to do this step again.
When you unlock bootloader, flash official rom or xiaomi.eu...

You could flash official xiaomi fastboot rom with Miflash tool: this flash recovery and MIUI also with BL locked.
Then you'll use miunlock tool to unlock bootloader
GGelmi

did your problem solved?
