relock bootloader - Huawei P9 Lite Questions & Answers

Hi,
Can I relock my bootloader while TWRP is installed? I want to get OTA updates back as I am not getting them because of the unlocked bootloader..

To relock the bootloader you have to flash the oeminfo.zip or use the dload method to install stock ROM

Can i unlock bootloader without rooting?

I am trying to change my Note 3 (SM-N900K) firmware but first when i try to flash the recovery after the flashing the recovery did not change what should i do?
Thank you
You must unlock the bootloader first!
are there any other application or an easier way to unlock bootloader without rooting?
I am not familiar with the n900k but using an app to unlock the bootloader if the bootloader is not locked will probably brick the phone.
Are you booting right into the custom recovery as soon as you flash it? If you flash recovery and just reboot to the rom, the stock recovery will overwrite the custom recovery.

lock bootloader

first of all,notice my problem warranty check (not that message appear after logo), warranty employee check device in bootloader ,
so i can remove message with flash stock rom and recovery , and when i get info about bootloader gave me it's LOCKED , but in bootloader screen two line with red color shows Phone unlock(it's shows the phone at least one time unlocked and warranty was void) and frp unlocked.
The question is HOW TO FIX IT TO SHOW LOCKED WITH GREEN COLOR as same as device locked?
I don't think you can.
To my knowledge, the best you can do is fastboot oem relock unlock code, but that will leave you with the relocked status.
I've tried fastboot oem lock unlock code but that doesn't work.
Flash oeminfo via twrp it will LOCK not relock your bootloader and then you must use 3 buttons method to update on MM if you are on Nougat.

You didn't flash it correctly. if for nougat update.app must be 2.5GB.
Also it wikl fully LOCK, not relock bootloader.

You need to extract the zip file from update.zip and put UPDATE.APP in dload folder. That's how I locked bootloader on nougat.

but by this method app not installed , one file for rom and another for apps,
so OK , how can i test it? now i'm in nougat ,decompress zip file and flash it with 3 buttons, OK!
what about zip app file?
how to flash this one?
or you how done it . are you upgrade from mm to N ? give me your file and tell me how to flash it,
my phone is p9 lite vns-l21 , after downgrade to mm b 160 and in N b336..
i used THIS
When you upgrade to b336.
1. Unzip update.zip you flashed
2. Create dload folder and put UPDATE.APP inside
3. Reset phone and press 3 buttons
4. EMUI will update by itself and will lock bootloader after it's done.

i done it with flash oeminfo , now bootloader is LOCKED but when i go to bootloader , shown me "" PHONE UNLOCED "",
it's my problem!!!

What happens...?

... if you flash from the SD the stock firmware (full) of the same version you have already installed in a bootloader unlocked axon 7?
Relocks?
Thank you in advance
No, the bootloader will not automatically relock after you flash a full rom. But you need to reflash aboot to skip the bootloader unlocked message at bootup.
