Help please. - Huawei P9 Lite Questions & Answers

Hello so I'm using Huawei P9 lite
VNS-L21
And after unlocking bootloader I receive this message when I'm rebooting it:
Your device has been unlocked and can't be trusted
How to get rid of it? Because I want to sell this phone..
I really don't know how to relock it so please anyone help me.
P.s I have been flashed TWRP via fastboot..

I'm afraid you can't, the only way is to relock the bootloader

[Solved] Bricked P9 Lite

Hi, i have a big problem: my phone isn't starting up anymore. Before bricking my device, i was in b160(VNS L-21), then i decided to upgrade to Nougat. So i unlocked bootloader, flashed twrp etc.. Finally i got N working, after that i flashed Revolution twrp and ROM, everything fine. Then i decided to format data, just to get a "clean" ROM, but after this, my phone fell in bootloop and, i don't know why, i couldn't even get into twrp and if i try to boot into it, i just get stuck in the yellow text "Your phone is booting up..." forever. So i downloaded b160, extracted update.app and flashed system, boot, cust and recovery to try to get as stock phone was, but after that i couldn't boot into system: i just saw the yellow choices menu stuck with the same text "Your phone is booting up...", can't even see Huawei's logo. I tried to flash twrp for 6.0, but i couldn't boot into it cause it was replaced everytime by eRecovery. So i tried to install b160 from dload method and it worked but bootloader locked again and i don't have the password anymore, and after Huawei's logo there's just a black screen forever. I heard about some kind of "oeminfo.img" to flash before downgrading from N but i didn't do that cause i couldn't access twrp after formatting data. I tried to install via ota b100, b120, b130 without success, they all say incompatible firmware when i install them. I can just install b160 or b161 but they don't boot up. Please help me if u can, i'll really appreciate it

Try fastboot getvar all . Maybe it contains all the information you need
if not, dc-unlocker will do what you need. I've bricked my device and with their soft I've managed to write the full img. You should try only to unlock the bootloader service from them
You can look at the package of your P9 Lite. There should be a sticker on it with your IMEI.

Thank you! Now i have IMEI and Serial NR, i just need Product ID. Is there a way i can get this?
Edit: I DID IT! YAY! I got bootloader unlocked, i used Huawei Product ID Generator, and typed "HUAWEI Y300-0000" instead of "HUAWEI VNS-L21" in Reformatting Lock Huawei's page, and it worked like a charm! Thank you for your help guys, you're the best

What android version were you running?
Anyway try this since you're not gonna unlock bootloader with OEM locked:
1.if on MM place your extracted update.app(same as you were running or latest available) to dload folder on root of sdcard and install via 3 buttons method.
2.if you're on nougat 2 things can be done:
a. same as above in 1
b. or download the rollback file plus MM full update file, place In dload folder the update.app file from rollback and MM full update respectively, install one after another.
NOTE that all this methods don't require unlocked bootloader or custom recovery, so try this above.

Ohhhhhhh good explanation friend.
Can explayn to all how flash TWRP with Bootloader UNLOCKED....but w/o OEM lost, so with Serial 123456xxxxxx????
I've flashed by Professional tool, BOARD + FULL Update.App + Custom fw (vendor/country), flash perfect but phone always in Bootloop becouse "Bootloader Unlocked" and Fake Serial.
Explain please, is easy when phone isn't Bricked and can enter in "Manufacture Mode"....but with phone only in Fastboot or Recovery how you do?

P8 Lite 2017 ReLock Issue

Hi,
I Have P8 Lite 2017 (PRA-LX1C432) Europe Dual Sim Mobile Phone Running Oreo 8.0.0.380. I have unlocked my bootloader directly by clicking unlock bootloader in DC-Unlocker and my bootloader unlocked but i dont have the unlock code. Now i flashed twrp at erecovery instead of recovery because we need to wipe data from stock recovery many times now i want to lock the bootloader with twrp installed as erecovery. I downloaded locked oeminfo file and flashed it with twrp as well as bootloader but my bootloader is still unlocked how I can lock it ?
Why no one is replying to my question ? Its my second thread and no one replied to it. No one replied to my previous thread as well. What's the matter ?
