[Q] Can't boot into fastboot - how to solve this problem?

Good evening guys,
There's a really strange problem on my Huawei P9 Lite VNS-L31. I'm not able to boot into fastboot mode. I tried to boot with Power + Volume down and adb reboot bootloader, but in both cases it's just restarting in the normal way.
Another interesting fact: I unlocked the Bootloader, but there's no warning message before the boot animation as it should be. I had these warning some time ago and I'm not sure when it has stopped to warn. Maybe at flashing the B161 to a B160.
I'm currently on VNS-L31C432B160. Do you have any tips for me? How to boot into fastboot?
Thanks!
Vincent

I solved the problem! If anyone has the same problem, try the following:
Shut down your phone -> open ADB command prompt on your PC -> press and hold Volume Down button (nothing other!) -> connect the USB cable to your phone -> your phone should now be in fastboot -> "fasboot reboot"
Now I'm able to boot normal in fastboot again.
Problem solved - thanks!

Hello, I know i'm late, but did you solved your problem ?

For fastboot with p9 lite:
PowerDown
eject a usb from PC
press VOL DOWN and INSERT USB in PC
let'go in fastboot

Is it possible to totally brick phone?
I have installed B170 version for VNS-L21, after it, in fastboot what I did was unlock phone with unlock code.
After restart my phone is only on screen:
"your device has been unlocked and can't be trusted"
"your device is booting now"
And nothings happen
I can't boot to
- erecovery - when I'm trying to boot by VolUp + Power its going to - "your device has been unlocked and can't be trusted" and "your device is booting now" and nothings happend
- install from dload - VolUp + VolDown + Power its going to - "your device has been unlocked and can't be trusted" and "your device is booting now" and nothings happend
- boot to fastboot because VolDown + Power is not working - its going to - "your device has been unlocked and can't be trusted" and "your device is booting now" and nothings happend
Even when I was connecting phone by usb cable to computer I have only info: <waiting for device> it looks like my phone isnt recognize.
Is there a possibility to help my phone ?

Did you hold volume down and then plugged your phone to your PC ?

Have to try it , hope it works

I have your same problem, kosiak07. Can you tell me if it worked?

It's not working, when I hold volDown and then plugged usb cable to PC it's going to screen: "your device has been unlocked and can't be trusted" and "your device is booting now" and nothings happend.
I think the only solution will be change motherboard

Kosiak07 did you fix it or just bought neu Mainboard?

What's your build number what version of supersu did you try to flash?
Shutdown your device, put your current build onto 'dload' folder in the sdcard and press the following key combo: POWER, VOL-UP & VOL-DOWN, it should enable automatic update process

Shut it down amd press those 3 keys combo.. upon seeing Huawei Logo and vibration, release the Power key while holding the other 2... That ought to do it

Man, your phone is badly bricked. If you don't have at least access to fastboot, then you're screwed.

Good for me to I have the same problem. I was trying to get to stock ( I have made it several times), but the last time was a fail... The whole process of sending firmware was ok. then a reboot and brick.
Now the huawei screen and the short vibration appears and shutdown.
I was trying everything.
In device manager the phone is displayed as mobile devices \ volume f:\ (drive letter)
in connected devices the phone is detected as
hi6210sft
Phone is not detected in fastboot or ADB.

I met this problem yesterday(I hope the identical ). Because I have two booting animations, one from Vodafone, I guess I shutdown early during installation. It just froze. Then it didn't boot and stock recovery didn't help
My solution needs some recovery software like twrp. Press three buttons at the same time until twrp mode. Copy zip file for SuperSU to phone or sdcard, then flash it. After that my phone works again.
You mentioned that you cannot start recovery. Try more. After installing twrp, starting it is quite annoying. Sometimes it just doesn't start or stock recovery starts. An alternative way is to go to whatever mode, and try adb or fast boot to reboot to recovery. Pressing button requires techniques which j don't have

I can't enter TWRP non combination is working for me. Installing firmware using dload from sd card also.

okay if non of these worked you can try flashing the whole update.app file by fastboot..
tools you will need
1- download the official huawei firmware from the official site
2- download Huawei Update Extractor
3- download minimal adb and fastboot
check the unbricking chapter of this thread
Note: to get in fastboot make sure you connected your phone to computer and press the vol down and power down buttons.. if none of these worked your phone is hard bricked .-. .. try opening the phone and reconnecting the battery worked with someone
if you need any help just pm me or replay on this thread hope that help you

Ok thx. I have already opened the phone to reconnect the battery
And then I was trying the combinations;
Battery connected vol- +power - Huawei logo and vibration and shutdown, no fastboot
Battery disconnected, vol-+power and connecting cable to phone - the same
Battery disconnected combination vol + vol - + ppwer, with sd card dload, the same
Battery connected combination vol + vol - power, sd card dload, the same
Any other suggestions?
The phone is recognized in Windows in device manager as mobile device as volume with a letter, I cant change the drivers to the right ones. I can't enter the storage it's unrecognized format.

Any other suggestions?

it is easy to suggest others.. I too advised you.. but today i am facing the same problem...
what I tried:
Reinstalling the same ROM using dload method
Upgrading to other ROM (using both dload and flashing 4 image method)
Downgrading
Restoring from the backup
At one point, the phone booted up all well except the Wifi Module... So I flashed another ROM and stuck again...

the worst thing that I don't have any connection to fastboot Each firmware installation method fails

yes, mine too... or I could say flashing succeeds but there's some problem with the boot partition... will get my phone today from the Customer Care and try again (if they can't repair).
you can try removing the back cover and unplugging the battery... that is one of the few things I will do today as I get my phone back..

ok made it back.. just flashed the boot.img from b594 (the one I was using when my mobile got bricked)... somehow made it back. But now I am having a problem with the battery. It doesn't charge when the device is switched on, only when the device is switched off... will see for few days, if there's problem will take it back to service centre again

I have already removed back cover and was trying to reconnect the battery to do clear run. But the only thing is discovered in windows is a driver for storage and I can't change the driver to ADB or FASTBOOT
Now I have connected phone w PC on adb devices I see only emulator-5554 device. In Device manager I see the storage as a Mobile Device.
Nope it was Bluestacks

Switch off your device and then connect it to PC but just hold the volume- key.. that should get you in fastboot mode... I did that and then flashed the boot.img of the current ROM. This should boot it up...

Nope it doesn't work I was trying it already

P9 Lite VNS-L31 bootloop, no recovery, no twrp , no bootloader

hello,
after install some rom, my p9 lite get bootloop. I manage to enter fastboot but phone was locked, so to install twrp i unlocked it.
After unlock i can't enter fastboot.
Screen "your devices has been unlocked and can't be trusted" appears, vol up+- power, nothing happens phone vibe 2 times and back to screen "your devices...".
My bootloader is unlock, can i flash twrp without bootloader screen on phone ? My phone is connected to PC but no device detected. Maybe at linux i can do something more than windows ?
Maybe i need to go to fastboot some different way ? i try to push 3 button after fist vibe and 2nd. Nothing work for me :crying:

For fastbooting u need to use volume down and power in the same time and the phone needs to be connected to PC, and for entering to recovery u only need to press volume up and power key.

Disconnect the phone from PC. Make sure it's powered off. Plug in USB cable at the same time while holding volume down.

Disconnect from PC. Power of the phone.
Press and hold only vol down, with pressing vol down connect with PC. Device should be start on fastboot mode.

i hold power button, if phone isn't connected to pc he is going off. Think is because battery is very low, led is blinking in red.
Then I hold vol down and connect usb cable, but how u can see on video phone weak up and go to booting.
I have hi suit last night as i mention fastboot works, but need to unlock phone. After that "your devices" screen came out and can't fastboot anymore
When i turning off phone with connected usb i can't turn phone off. After a second phone power on by his own.
If phone is disconnected longer than 5 min, then i push vol down and connect usb only red lightening shows up. I need to wait a while to phone start.

OK. When phone is off, if you connect with PC, phone should be start, but this is only for charging. May be, you don't have charge, so phone is not going to fastboot mode with vol down?
Now just connect the phone with PC for full charge.
You don't have any recovery? Custom or stock?
It can be happen?

When i start charge phone blinking red in led, after while phone vibe 1 time and go to booting now, but led don't stop blinking. I will try to charge it, but because of working screen, phone heat a lot i don't wanna burn it.
Before i made rollback and something gone very bad, emui update after 100 % phone don't boot up. Without usb cable i wasn't able to go recovery or fastboot. So i think i don't have any recovery i made backup of files with twrp but now i can't flash it.

after night without power, phone drain all of battery. Now i understood better what is going on. when i plugged usb cable, phone don't start bye it own, only red lighting flash for second .
I disconnect cable and connect it with vol down button how all of here wrote. Phone immediately weak up an go to "your device has been..".
It's look like after i unlock phone (bootloader) somehow i was able to corrupt bootloader files or even delete it. Some one can confirm that it is possible to crash bootloader ?

I have the same situation. I tried everything, Three button method, letting the battery run out completely, Vol+ and Power, Vol- and Power, connected to PC, not connected to PC. Every time I disconnect the charger, and reconnect it starts from 0. I read some other people here have the same problem. Send it to warranty and explain your rollback process unlocked the bootloader somehow (I mean the phone does do a lot of sh*ty sh*t, so this shouldn't seem very odd as well!!!) and hope that you get a repair/replacement and after that sell it on ebay hoping some stupid people like us in the first place will buy it and spend your money on a phone more reliable!

I managed to access the fastboot using the 3 button method in cold boot. Hold the Power key until the screen goes off and then release and hold down the Vol- key and immideately connect the usb cable to PC right before it vibrates or exactly when it vibrates (it's a matter of timing), and bingo you are in fastboot and you can flash system.img, recovery.img, cust.img, cache.img and boot.img from there, but this is not how I revived my phone. I used the 3 button method again when the phone was charged for like half an hour or so and the did the same cold boot trick and I could boot into the force upgrade environment (strangely this still didn't work whitout connecting the usb cable to PC), but it somehow didn't want to read the UPDATE.APP that I had in dload folder on my SD card and wanted to have it from my PC (I just felt it nad there was no indication of it ) so then I installed the DC Phoenix tool and payed 15 euros to be able to inject the complete UPDATE.APP to my bricked phone and the installation went well to 99% and failed, but I rebooted the phone and I could boot normally. Just to make sure I did a factory reset afterwards. Hope this helps.

Yes. I am actually writing this from my Huawei P9 Lite now. This phone is really a nightmare for modifying and customization. I'm not sure if I'm going to resell it or just wait a reasonable amount of time until some reviews from the next update come out and see if I might wanna take the risk and update my phone again.

TWRP install gone badly wrong i think

I have a problem after installing TWRP on my P9 Lite i have a screen saying:
Your device has been unlocked and can't be trusted
To Learn more, visit: long www adress
Your device is booting now...
Cant put a picture because i don't know how. But this is all it says, and then nothing else happens. Just stays on that screen. Can't connect to my pc or reboot in Recovery mode it always ends here.
Hopefully one of you guys can help. In a bit of panic.
Can't shut it down, everytime i try to turn it off, it reboots into this screen.

Can tell us some more information? Like what ROM are you on now, what TWRP you used etc..

Just tryed to make the dload folder on the root of my SDcard but still no success. I havn't been able to start boot screen other than this locked screen.
I have tryed to start with volume up + power both volume up and down + power and volume down + power. Nothing changes, just get this screen everytime.
Cant do anything, not even shut the phone down, it only reboots. I have seen other simular problems, but they have been able to get to the screen with 3 options. I havn't been able to come to that part.

Plug USB cable to your phone but not on your computer, restart the phone and as soon as it restart press volume + (or volume - I don't remember which is fastboot) and plug the USB cable to the computer. So you can check if the bootloader is unlocked

After i ran out of power and the phone went out. I have been able to boot again. Anybody who knows a bootloader i can install that works on my phone for sure. My bootloader is ****ed up.
It is unlocked now, so i have to be sure it works.

MI A1 Fastboot

MI A1 does not enter the fastboot, appears the message "your dvice software cant'be checked for corruption, please lock the bootloader" Two things, first I am layman, I understand little, the other and excuse the translation, was machine translation.

The message has nothing to do with the Fastboot. That message is a normal reaction when the bootloader is unlocked.

When the message appears, release the buttons and try again to do the same, hold the buttons together for about 20-30 seconds until the phone doesn't enter Fastboot. I Don't see a reason why the phone wouldn't enter Fastboot if you only unlocked the bootloader.

If I hold on, the same thing will happen 10, 20, 50 times, I've already tested it.
If I release the volume - and power buttons, the unit comes in and I have to turn it off to try again :crying:

Can you boot into the system at all? Does the phone work? How did you get to the point that you can't enter Fastboot, what happened exactly?

As I said before, I do not understand much of this subject, the phone works normally, all functions are working, I switched on it some time ago, but I can not remember what I did right for it to be without fastboot

If you don't understand the subject, why did you want to boot into fastboot mode in the first place? No offense, just aksin'.

Good question, did not offend me. I figured it was time to start learning about it, I was thinking of installing the Google Pixel rom

With the phone OFF:
Press Vol- and Power, when Bootloader screen appear just release the power button, so continue to hold Vol- until the fastboot screen.
It's the only procedure for fastboot on our device.

It did not work, the error message appeared and as soon as I released the power button, came on the device. This problem has left many people without understanding, I just did not give up, because I do not accept that only my cell phone this function does not work

Does your phone have root? If so you can use a reboot app from the play store to boot into fastboot.

Install adb drivers, enable USB debug then open command prompt and type "adb reboot bootloader". Phone should reboot to fastboot mode.

adb reboot bootloader worked kkkk now that the fastboot worked I will solve if I try to put the other rom, or if I leave as is, but if any of you are where I find information on how to change the rom and if it is really worth it, me Please, thank you very much at all
