How to unlock bootloader if phone won't start up. - Huawei P9 Lite Questions & Answers

My phone is bricked and I was thinking about flashing it via adb fastboot, but I cant since my bootloader is locked, I tried to get the code but it is asking me for info which I can only get with phone turned on, is there anything I can do?
I got IMEI only, but I also need Product Model, Product Serial number, Product ID. (I can access those only in settings and in dial pad if I am not wrong).

See the back of phone, what type of model is? VNS-???

i have mate 10 lite same problem,bootloader is locked so can i use dload method,and where to get the stock firmware

I have executed these commands and after from this moment, the screen of my device is black and which key or combinations of keys I press nothing works..
Code:
fastboot flash preloader preloader_begonia.bin
fastboot flash lk lk.img
fastboot flash lk2 lk.img
Disconnected the cable, connected the cable, holding the keys for a longer period, holding them for a short period. Only power key, only volume up/down, combining power with volume. Nothing works. When connecting it to the computer, I do see device manager constantly refreshing. But both fastboot and adb are not finding any devices.
When holding the power button for more then 10 seconds, I do feel a small vibe but thats all. Nothing further happens, also not when connecting it to the PC or disconnecting it from the PC.
Anyone any idea what I could to to fix this?

[Q] My LG G2 is is bricked with no download mode and cant get to recovery!

Lg G2 AT&T, The power button and volume down button does not work, when i try to get into download mode it goes to "[2130] Fastboot mode started" . I flashed the wrong rom for my device, usually i can go to recovery but for some reason this time it wont let me. At this point i'm pretty hopeless, I have looked on Google for solutions but you either need recovery or download mode. Please help
Have you tried entering recovery by turning off the phone...pressing power and vol. down...then, while still holding the vol. down, release and press again the power button once the LG logo appears...then release the vol. down button once it asks if u want to factory reset and pressed the power button three times to attempt to enter recovery?
---------- Post added at 06:43 PM ---------- Previous post was at 06:36 PM ----------
Read this entire post and follow VERY carefully if your symptoms sound the same (two different sets of symptoms with different solutions). I was able to bring my phone back without recovery, download mode, etc. However, I did not have the fastboot error. http://forum.xda-developers.com/showthread.php?t=2681089

Hardbricked/Softbricked Zuk Z1

i can not access fastboot mode and nor recovery mode.
when i press power button only shows zuk logo and shows recovery logo for less then 0.1 sec and screen starts flickering until battery power goes to 0%.
please help.
these happened when i was updating cm 13 while 'update cyanogen recovery' option is turned ON.
press and hold on power button till your phone switches off.
after it is off just press and hold volume up and volume down and connect it to usb on a pc, let go volume buttons when you see fastboot mode.
once you are in fastboot mode you can download and flash the fastboot file if your bootloader is unlocked.

So I followed these steps:
1) Long-press the power button. Phone restarts.
2) While restart, hold +vol and -vol.
3) Immediately after restart, plugin USB cable to computer.
That didn't help. Did I miss anything?
No . than take off the cover and unplug buttery .

Okay guys so I had the exact same problem just hours ago.
I accidentally flashed a kernel in recovery partition (Ik lol xD)
So here's what i did.
I searched around a lot and didn't find an exact answer. Then i came across something.
If you can, remove the back cover and disconnect the battery and then connect it again.(Look it up on Youtube)
If you can't do so, wait for the battery to fully discharge.
Then, press the vol+ and vol- together and wait for 2-3 secs and then connect your USB cable.
Don't press the power button or you'll just end up in a bootloop.
My phone directly went into fastboot mode.
Hope I Helped.
hold voulme + button and power button , and then continuously press volume - button 10-15 times! it will boot twrp ! i was facing the same issue ! This worked for me!

Let your phone to discharge to 0% then it would automatically power off. Then press and hold volume up button and connect to pc. And you r there in fastboot.

No no download mode just vibration and when i connect it to pc it shows Mediatek preloader
u have to turn off the phone
then press volume down and power button
when the download mode appear just give us a screen shot to help you
If you hold volume down and power long enough it should force the phone to turn off even though it's bootlooping

No download mode nothing on screen what ever I do nothing changes so I started to believe that the phone is dead but it's recognized as mediatek preloader when connected to pc
you can try to turn off the phone by the hard way
maybe the phone is recognized as mediated device because of precessor
try holding power and volume up for about 20 seconds or
power and volume down
if its restart just enter download mode and post a screenshot

My p9 lite _-53 its stuck in the huawei logo

hi guys i'm using Huawei P9 Lite VNS-L53
i rooted my phone two days ago and everything was ok, then i left my phone charging and in the morning my phone was turned off and when i tried turning it back on, it got stuck on the huawei logo and i cant get past it.
i had bootloader open, twrp and root
phone doesn't react to my key combinations (power, power+volume up, power+volume up+down vs.. you got it.).
then i cant connect my phone to my pc, it doesnt make any sound when i connect it and my computer doesn't say anything about about my phone being connected.
All my impressions are that's it. how can i fix it? or is it a hard brick or something unrepairable?

Can you get into fastboot?
You have to boot it into fastboot. You can't turn off it now, but you can reboot it. Connect to your pc,press the power button for 10 seconds, it will hard reboot, but when it turn off press the vol - pressing power. You will enter to fastboot.
Now unlock again the bootloader
---------- Post added at 12:48 PM ---------- Previous post was at 12:47 PM ----------
If all success, you can flash the twrp and flash the ROM
Ok, so i have to connect my phone turned off to the pc and then press the power button for 10 seconds? Then the volume down button?

You can know because there is a write and a robot icon.
So, try press power + vol - together for 10 seconds.
