vol up worked.
thanks
I have entered "adb reboot fastboot" but it only reboot to the system but not reboot to the bootloader.
I have already selected the option about OEM unlock in the developers settings page.
4 me too...
I got there by hitting enter and immidiately pressing the vol up
I got a question:
I guess the pc doesn't recognize my device... But it turns out 4 other pcs don't neither...
Every time i get to bootloader, entering the code 'fastboot oem unlock' in the command window, and all it does is waiting for the device....
What should i do? It drives me crazy

Dear Community,
I got my Note 3 Pro Snapdragon Version today and I tried unlocking the bootloader, installing root and TWRP.
Unfortunately after I installed TWRP, WiFi didnt work anymore so I wanted to go back to where I was before.
i tried flashing the GlobalRom with the MiFlash Tool but somehow I'm now stuck with a bootloop.
The phone starts up and shows the MI Logo but doesnt go on. I tried booting TWRP temporarily via fastboot commands so that I can try to flash flashable zip files
but it doesnt let me execute "fastboot boot xyz.img" anymore because my device is locked.
I would really love to hear any solutions or ideas. I dont want any root or something anymore. If someone has an idea Im very happy!!!
thanks a lot in advance and tell me if you need any more infos

1. keep vol + and vol - pressed while connecting USB to enter adb mode
2. check if phone is connected with "adb devices" in command line, if phone shows up, enter "adb reboot edl"
3. now you can flash via MiFlash

First of all, HUGE thanks for your fast answer!
Unfortunately I couldnt get this to work. Since I am stuck at the Logog screen here is what I tried:
Pressing both volume buttons while Logo Screen and plugging USB.
Pressing both colume buttons while fastboot screen is up.
These two didnt enter adb mode, I guess because of the bootloop I'm in
I also tried antering recovery mode with volume up + power button. Pressing both volume buttons didnt help either but when I am in recovery like that it shows my device in adb as "sideload" device.
Maybe that helps ? Can you give further advice or am I doomed?
My idea would be: Is it possible to reflash the device completely only usinf fastboot? The only thing I seem to be able to enter is fastboot...
Is there a way from fastboot to "working phone" ?
or maybe through the "adb sideload" state?
thanks a lot in advance!
Paul
EDIT
tried installing via "adb sideload xyz.zip" command but after shortly showing a status bar on phone screen it aborted and said "Total xfer: 0.00x" on PC screen .
Also: I read "adb reboot edl" brings you to download mode so you can flash something. Tried it but the phone just rebooted the normal system, so it stuck on Logo again...
search miui forum for unbrick, there is 2 or 3 method without opening your device
exp: http://en.miui.com/forum.php?mod=viewthread&tid=257227
Unfortunately they all do not work because they always require either a phone in download mode, and i only get to fastboot and adb sideboard or they require flashing something via fastboot but I can't do that either because it says my device is locked if I try...
Any suggestions how to flash a ROM with fastboot only or with adb sideload?
Thanks a lot

I Had The Same Issue Brother ! There are only 2 Things which you can do now .
1. Test Point Method to enter EDL
2.Give it to Service Center . I Gave Mine to Service Center ,They Fixed it in 30 mins or less and it was free

Can I do the test point thing myself or is it risky?
What kind of service center? A general mobile phone repair shop or a Xiaomi special one?

I've been facing the same (or a similar?) problem about a week ago but managed to get out. Knowing me for having a head like a sieve I made some notes, sadly quite rudimentary
Did you try to flash with MiFlash after "adb reboot edl"? If I remember rightly after "adb reboot edl" you got the logo like booting another way, but the light is blinking red. Then I could flash via MiFlash.
I'm quite sure that if you get a "reboot" after entering "adb reboot edl", your phone will be in edl mode.
I will try that this evening when I am at home again and report. Thanks

Do you have another idea? :/
How did you unlock the bootloader, via official permission or that unofficial hack?

Only options you have right now are:
1) using test points method which is a but cumbersome and voids warranty if you care about that.
2) go to a xiaomi service center of you have any nearby.
It is hard bricked.
So there is absolutely no option to unlock bootlader via adb sideload or fastboot ?

Apparently, no! Whenever using unofficial methods, read precautions carefully and you missed all as I can see. Wait if someone can help you out.
apply official unlock. then unlock your device from fastboot mode.

That sounds nice and easy. I already applied for official unlock.
But: do you know if u can use the official unlock now? I can only access fastboot and adb sideload mode. Is it possible to activate official unlock from there? Or do I need a working ROM rather?
I would have thought that official unlock doesn't work from fastboot /adb sideload...

I have the same problem. I made the same mistakes as shisaya24. I have followed every procedure for unbricking and nothing works. I even applied for an unlock code and got it from Xiomi. I used their mi-unlock app which requires fastboot (pwr/vol-) but it gets to 50% and bombs out. It states it can't verify the phone. Can anyone please help me??

out of sheer desperation I tried MiPhone again and after a few tries, MiPhone started updating the OS. My phone now works again and I have an unlock code as well.
I have the Huawei Ascend Y300-0151 and am trying to unlock the bootloader, in which I cannot get through their website because it's really buggy and won't accept my information.
So these are the steps I've taken:
- Download SDK Manager and install platform-tools and Google USB Driver
- Boot my phone up and connect to the PC
- I can run the command 'adb devices' and my device shows with a unique ID.
- Boot my phone into recovery/download mode (purple screen).
- Connect my phone, the PC detects it.
- However, when I run the command 'fastboot devices', nothing shows up.
Yes, I have installed a driver for my device and it's now showing as Android Bootloader Interface.
I've run out of ideas and have been googling for answers for a very long time, but to no avail.
Any help would be greatly appreciated, thanks!

Given that your attempting to unlock the bootloader of your Huawei device, you should probably send an email to Huawei support requesting for your bootloader unlock code (thats what I did and they replied asking for my device information, and I gave it to them to which I then got my unlock code). For ADB to work you need to boot into fastboot mode, not recovery, then simply use the bootloader unlock code with the following command in cmd: fastboot oem unlock <insert your code here>
And then your done. Be cautious when unlocking your bootloader as you should make sure you have your developer options enabled and the "allow bootloader to be unlocked" option enabled as well.

I have e-mailed them 2 weeks ago and they are not replying. You're meant to do it through their website, but as I've said, I supply the correct information and it either re-directs to a page that is not there or says I am not entering my information correctly when I've done it over and over again.
The purple screen is fastboot mode isn't it? Because that's the screen I'm entering the commands in, but it's not showing up. I cannot enter in a code for fastboot oem unlock because my device will not be recognized by fastboot in the first place.
So before I am to unlock my bootloader, I'm trying to get my device recognized by fastboot.

You can send them an email to get the unlock code, trust me, thats what I did. Maybe try contacting them via their support section of their site if you didn't do so last time.
By the "purple screen" do you mean the screen with options such as "HBOOT", "Fastboot", "Reboot" etc.? The "fastboot devices" command should work if it is recognised by the command "adb devices"

I'll give it a go again, thanks.
By purple screen, I mean holding down the power button and both volume control buttons and the screen boots into a purple screen. Just a purple screen, that's it. I can boot into two other modes by holding down the power button and the volume up button and another by holding the power button and volume down button. I don't have a boot mode that displays any options as you've listed above.
EDIT: I'm in fastboot mode now! It was the mode where you hold down the power button and volume down button. Hahaha. I'll let you know how I get on with unlocking the bootloader. Thanks for your help
No problem, if you found my replies helpful please press the thanks button! It is much appreciated!
When I'm try to boot in fastboot mode the fastboot mode (volume down+power) will only display for about 10 seconds and then it will reboots itself into charging mode. doesn't matter if i use the key, or even use adb commands to get there. it will still reboot itself in short period of time.
why is this happening? i just want to unlock my bootloader thats all...
Please help me... thanks in advance....

Your computer is unable to detect the phone in fastboot mode. Uninstall and reinstall the fastboot drivers, the proper ones. If successfully detected it should not be rebooting.

Im having this issue now on my redmi note 4x.
Do you have a solution? Thanks
Man, you need adb bootloader interface installed properly.
Open device manager, and you'll see something popping out when you connect your device to pc on fastboot mode, there you can see what's wrong. So all you need is update that wrong driver (the one that popped out once you connect your device in fastboot mode) and install redmi note 4x driver, just ignore your disappearing fastboot mode in your device, keep install it. You should have your redmi note 4x driver prepared btw, you can google it.
Good luck!
use USB2 port, do not use USB3

That is because your computer does not make any connection with your phone. Are you sure that you have all drivers installed. You can install fastboot drivers with mi flash tool but before that write this command in an admin cmd - bcdedit /set TESTSIGNING OFF and reboot. Now you can now install the fastboot driver from mi flash tool and try your luck

So drivers are needed for fastboot flashing a xiaomi phone?
Why I didn't need drivers to use fastboot with other phone manufacturers?
In these phones (oppo, op) the phone stays in fastboot mode until you exit or shut it down.
I think xiaomi did a bad move with this.
───────
EDIT: It works in debian without any additional drivers.
Fastboot recognizes the xiaomi phone with "fastboot devices" command.
So it was as you said.
Hey all i dont know what the deal is but ive got an lg g5 that just will not boot to the bootloader. I've tried factory resetting it and all the methods to get to bootloader just reboots the phone fully. Adb reboot booloader, key combos, nothing seems to work. Any ideas??
First, connect your smartphone with your PC; plug in the USB cord in order to establish the connection.
On your computer access the Android SDK folder.
From there open a command prompt window: press and hold the Shift keyboard key while right clicking on any blank space.
Next, in the cmd window type “adb reboot bootloader” and wait while the bootloader mode is displayed on your smartphone
That's basically what I did and worked first time..make sure the adb and fastboot package is installed and open the command window from that folder

Did all that.. I mean I've flashed custom recoveries and roms to other phones before and never really had a problem i couldn't google..this has me stumped. It simply refuses to even access the bootloader.
If it helps it was a koodo phone and is running the latest official patch from lg on nougat. The only thing i could find online was that sprint supposedly removed all access to the bootloader on theirs, but i cant find any real info on that either. It reboots when i send the adb reboot bootloader but its like fastboot just isn't there..?? It reboots right back to the android home screen. Ive tried all possible key combos as well... Ugh
Which model is it..mines the h850
Ive got the h831
I think I've sort of answered my own question. From browsing the forums it appears the Canadian variant has the bootloader locked down and inaccessible, which would explain a lot..lol.. I really hate when this kind of thing is done to the consumer...ugh. Back to xiaomi i guess lol

Interesting - my xianomi hat an locked bootloader and i had to ask for permission (for the phone I bought!) to unlock the bootloader.
LG is also locked, but the unlocking procedure is way easier.

Hi guys,
This Is my first post so I hope I do it correctly. As the title says I am having problems with fastboot on my Acer Iconia One 10 B3-A40. I have enabled developer settings on my device and turned on the setting to unlock OEM. The problem is when I try to run the tablet in fastboot mode to unlock the OEM through ADB commands. When connected to my computer and running the command "adb devices" it shows my device Id and that it is connected. I then run the command "adb reboot-bootloader" to which the tablet switches off and makes the chime that it was disconnected from the computer and makes another chime and connects back onto the computer, the screen on my tablet remains blank with no indication it is in fastboot mode. When I run the command "fastboot devices" my device id shows up again that it is connected. When I originally tried to flash a patched boot image of my stock firmware it went through the process and failed mid way through saying it couldn be done cos the device was locked. After that I googled a bit to see what to do so that’s when I realised OEM unlock was to be switched on in developer settings and also using ADB commands. After returning to fast boot mode I ran the command "fastboot oem unlock" the 3 dots come up on command prompt to show the process is going but nothing happens on my device. Nothing will happen if I press the power button or the volume down button but if I press the volume up bottom, on command prompt it shows OKAY and then the amount of seconds it took to complete, the time changes based on how quick or long i take to press the volume up button but the device remains locked. I have being trying to find a solution for days and have searched everything i could find before making this post. It would be greatly appreciated if someone could help.
