fastboot never start after update to android 6

Hy
I had an unlocked bootloader phone. Yesterday I flashed the new Android 6, Europe version from the Huawei blog forum, no beta, on my Huawei GX8. I used the method, dload on SD card, Phone off an the press Volume down+volume up+Power button.The flashing was normaly.
Now the phone starts normaly but I can´t start fastboot. When the phone is off and i press Vol down + Power the phone start the android system and the Huawei logo is coming not the fastboot Modus. I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!

Should be connect the charger cable to the phone.
charger or computer
excuse me for bad english

And when you use adb to reboot to bootloader, what happen? Do you have "Minimal adb and fastboot tool" installed?

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.

i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.

Here is screenshot from minimal adb...
Phone must be in MTP mode.

And here is phone in fastboot

Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

Just reboot to fastboot and flash surdu-petru version of TWRP recovery 3.0.2 with command "fastboot flash recovery xxxxx.img". And than reboot to recovery and flash supersu zip.

TWRP installed but no OS. Udev problem?

Hi guys!
After years playing around with android roms and devices it looks that i probably brick a device for first time.
I'll try to be brief, but if you need more info it will be a pleasure give it to you.
Now my MI6 have recovery cofface 3.1.1.-0 installed but no os. I can reboot on bootload with keys. The problem is that im unable to push a zip into the device. Commands "adb devices" and "fastboot devices" return no devices founded.
a) OTG: Recovery doesnt allow me to mount USB-OTG. I enter in Mount and when i click over USB-OTG it highlighted but the checkbox still empty.
b)Plug into pc: The phone appears and disappears each second. Tried multiples wires.
Udev not found warning shows up when I click in the device before it disappears.
c) ADB sideload: not working, cause i cant reach MI6 from PC.
I add some stuff i see in logs and could be interesting:
When i use sideload:
Code:
I: cannot find file /sys/class/android_usb/android0/idProduct
I: cannot find file /sys/class/android_usb/android0/idVendor
When is in appear/disappear loop:
Code:
I:[MTP]Mtpserver::run fd: 20
E:[MTP] request read returned -1, errno: 5 , exiting MtpServer::run loop
I tried to recover it from Windows and Linux even from FWUL liveiso but all same results.
Any idea is appreciated, thanks a lot!
PD: Excuse my English Besides not having a good level, I'm tired of being all day trying things

That recovery is ancient. Just use fastboot to flash a stock rom with miflash. Then flash latest twrp.

This is the first roadblock for him.
if fastboot devices can't detect his device, then any fastboot command to flash a partition is also invalid.
Have you tried different machine to do adb devices/ fastboot devices?

Yes, linux and windows. And drivers are OK cause it worked before.
I think when i wiped system the device got corrupted someway. Now if i plug it into debian machine the computer detect the phone one sec., then dissapear other second, appear again... and so on.
My idea was to flash new recovery from otg but recovery didnt mount the device. Im researching for some way to mount it manually but at the moment not success.

I'm assuming it's a driver error. Few years ago i had a mtk smartphone and somehow i managed to hard brick it, PC recognize it just for 2 or 3 seconds and that was because fastboot drivers didn't installed so i had to install it manually from device manager, for mtk drivers name was preload 89xx (driver must be for specific motherboard model number), i opened device manager, boot phone in fastboot mode, connect it to pc and on the short time wen the PC recognize the phone i hited right click and choose update driver manually, i believe it could be possible to do the same thing with mi 6, i don't know if there are separate drivers for fastboot mode to be able to install them.

Lg g4 h815 suck in fastboot mode

Hello,
My H815 phone is stuck in fastboot mode.
Whenever i press the power key the phone goes directly into fastboot mode.
I wanted to reset the phone using the phone's menu but straight after that the phone booted directly in fastboot mode and it's now stucked.
I believe that the bottery should be dead as well.
The host has it's bootloader uncloked, however i cannot install TWRP as i receive a message command: unknow in ADB when i try to install the recoevery.
I tried different USB cables and different ports of the same |laptop, currently runnin windows 7 with all the drivers.
Looking for are feedback on how to install the recovery and get rid of the command:unknown error

Search for FWUL from Steadfasterx.
download-> flash->connect-> open Comannd-> type "fastboot flash recovery recovery.img" or "fastboot reboot system"
Which command are you using for installing TWRP in ADB?

Insufficient info.
Are you able to boot up? Are you able to boot to bootloader? Do you have TWRP and are you able to boot to it?
Is your bootloader unlocked? Are you rooted? Is USB debugging enabled?
Does "adb devices" / "fastboot devices" command find your phone? What ROM?

sorry ,
I think I am able to boot to the bootloader (but I cannot see it since my screen is broken)
my bootloader is unlocked , device is rooted and USB debugging is enabled
while pressing Power+Vol UP I can get into fast boot and see my device on fastboot devices
anything else I need?

To clear things up, TWRP is recovery and not bootloader. Fastboot is bootloader.
So, if you can boot into TWRP, you should be able to use adb commands. Try booting into it, then try "adb devices" and see if it's properly detected (adb reports device's serial number and status "recovery"). You can then use "adb pull" command to get your data.

Ok, an alternative then:
- download latest TWRP .img file to your PC
- open command window in folder with the file (Shift + right click > open command window here)
- boot into fastboot (Power + Vol Down) - you said you managed that before - and connect the device to PC. If it's properly detected in fastboot, you can boot custom recovery with "fastboot boot <recovery-name>.img"
Phone should now restart and boot into previously downloaded recovery. Now you can try and see if adb works.
Easier option would be simply "fastboot reboot recovery", but that command is non-standard and doesn't work on OP3 if I remember correctly. You can try though, nothing to lose.

ADB and fastboot cannot detect the phone

Hello, I have two unlocked Pixel 2XL, one works without a problem, it is detected by adb and fastboot. The second one during boot has bootloop. When I try to turn it into fastboot mode, the screen of this mode is shown, but after connecting the cable (which works on the first fully working phone) and entering the command "fastboot devices" nothing happens. In device manager I only have 'device not detected or working incorrectly (code 43 or sometimes code 10). When trying to enter TWRP, the phone completely stutters and displays only the TWRP start screen without any other symptoms. I have good drivers installed because the computer detects this working phone without a problem ... Do I have a damaged USB port on the phone? Is there another explanation and solution for this?

Most likely the culprit is either out of date platform-tools or TWRP...
What version of adb, fastboot, & TWRP are you using? Also, how are you booting TWRP -- there have been many cases where people would use the command "fastboot flash boot twrp.img" instead of booting temporarily...
Hope this ends up being helpful as that means it resolves it...

Are you able to fastboot boot the latest twrp.img?
Might want to give Deuces script a whirl. I've seen this fix situations like yours.

ADB version: 1.0.41 29.0.5-5949299, TWRP: twrp-pixel2-installer-taimen-3.3.0-0 Latest Rom istalled on this phone is Havoc OS 2.8 for P2XL. I trying to enter TWRP via fastboot and choose recovery there, but stuck on TWRP logo... When I try to enter a command: "fastboot boot twrp.img" receives a message: <waiting for any device>
edit: Deuces script log says: "Welcome to Deuces Flashing Script!

But cable and drivers is good because other pixel 2xl works fine with it...

This might sound crazy, but, at least try another USB A to C cable, and other ports on your pc. The P2XL is notorious for being finicky when it comes to cables and ports. What might work for one phone, doesn't necessarily mean it will for the other. Make sure it's a 2.0 USB cable as well :good:

I checked four different cables and all ports on my computer and still not lucky... I even checked on another computer and still the same

Then it's likely a hardware/port issue would be my guess.

Meh, so I will look for a workshop nearby that will exchange the port for me and check later

I would also suggest that you re-download EVERYTHING...
You may be stuck with a "buggy" TWRP image file or platform tools....and/or go against conventional thinking and download and try an older version of TWRP to see if it does it at that point as well...
In either case, hopefully you get it figured out and good luck to you...hope this ends up being helpful!

There were a number of Pixel 2 XL's that did suffer from charging port issues, including my original. Luckily I was still under warranty and was issued a replacement. The phones would charge fine but data did not transfer as with adb/fastboot, nor would Android Auto work.

Did you open your command prompt directly on the platform-tools folder?
When you typed in "fastboot devices" did you see your device ID Number?
Are you using a 2.0 USB A to USB C cable?

Based on your error, I'm guessing all the files in the Full Factory .zip file (all 6 of them) aren’t residing there with the adb & fastboot .exe files within the platform-tools folder. Make sure you’re seeing those 6 files (you will have a two .sh files, two .img files, one .zip file, etc.) with the .exe adb & fastboot file.
Then, also make sure that you are directing your powershell or command prompt to the correct “platform-tools” folder, because many other people seem to have multiple “platform-tools” folders and they end up directing to a wrong folder…
Hope this ends up being helpful…

I fixed it! The error in fastboot mode probably came from a file that I extracted from winrar, when I downloaded the factory image again and extracted the files this time through 7zip and copied them to the platform-tools folder and double-clicked flash-all.bat fastboot started and the installation was successful! Thanks to everyone who wanted to help me solve this problem <3
ps. btw, I haven't replaced this broken port on the phone... just started working again...
