First I must say, I searched all over the internet for answer to this problem. None of the topics I read had matched my problem.
I want to unlock my bootloader so I can flash custom recovery and get root access.
When I want to access the bootloader ("adb reboot bootloader"), in my phone all goes fine (I see on my phone the Fastboot instructions, etc). The problem is in my computer that fastboot won't recognise my phone anymore. When I want to get the device-id, fastboot is stuck on "waiting for all devices". When I want to see the list of devices, ("fastboot devices"), I get nothing, wether my phone is on bootloader mode or not.
I installed all the LG drivers, including the ADB one. I am in USB debugging mode, and I disabled OEM protection.
Android version is Lollipop.
I need help on this matter, thanks in advance.

I know mine can be unlocked. I actually can get to the bootloader via ADB. The problem is that fastboot won't recognise my phone afterwards. (I believe it's the european version of the H815 model, and according to one-click-root app, my phone can be safely rooted. Also my Lollipop version is 5.1.)
There are other few issues also:
Fastboot won't recognise my phone, even if the phone is not in bootloader mode.
Windows will recognise all of the LG related drivers including the ADB related driver, while the phone is powered on normally.
However, it fails to do so, in bootloader mode. I see non working driver in Windows 7 Device Manager, under "Other Devices" by the name "Android" with yellow exclamation mark. Nothing else.
Still looking for advice...

I have the same problem, adb detects my phone but fastboot does not. Same Phone btw
Still no solution until now ? I have the same problems
My device is H815
Hi !
I have had this problem too...solved with strong battle to understand myself...
My solution : when you have installed driver ,when your phone go to fastboot mode and the pc don't want to reconize the phone : on the pc on windows go to harware manager (config panel) and you can see in theory "android" with a "?" ==> you have to install manually the driver by searching somewhere on the harware list "android adb interface " (i don't remember where it is) ==> your phone wil be reconized ! And you will have the 2 lines of ID on the adb comand interface....and follow the tutorial...
I have read hundreds of issues with driver problems when it comes to windows.
Please try Linux instead. There are live distributions like Ubuntu available. Install it on USB stick and start from there.
No driver issues anymore. Just works.
.
@steadfasterX it need some knowledge for to use Linux OS for adb thingsv (unlock bootloader ,instal TWRP,rom,apps...etc...) ? maybe you can do a small tutorial for to help ?
For windows i have found these pictures for an eventual help (see ZIP on attach file)

Well there are hundreds of guides out there just use google...
adb and fastboot working the same way under Linux so there is no need to have a specific guide for linux.
I haven't tested that guide here but it looks very good as a starting point:
http://forum.xda-developers.com/showpost.php?p=44739402&postcount=1
As said there are other maybe better guides but Google will tell you.

@steadfasterX thank for your link ,it's useful for people who have problem and read this thread
It's not for me .... i have my bootliader unlocked ,twrp...( and this fabulous Imperium MM rom !!!! )
Hello,
I've bricked my phone and now it just turns on to bootloader, all options in bootloader except turn off just loops it back to bootloader where it says "continue the fastboot process".
I've download the xFSTK_ZE551ML but it won't install the moorefield driver it detect it for only a few seconds and then change to android-phone driver, i believe moorefield doesn't work on bootloader but i can get the phone to hang on something else.
I also can't acess via ADB, when i type adb devices, no device is found.
Also tried the Asus FlashTool, but the raw files i tried (WW_ZE551ML_2.15.40.13_20150506.RAW) didn't work, i believe because it's Android L and phone was on Android L.
I've searched alot but haven't found a solution, can someone point me in the right direction?
Thanks in advance.
What happens when you type "fastboot devices"?
Nothing happens with that command.
It's working now, after i tried several raw files, it worked with "WW_ZE551ML_2.20.40.194_20160713.raw".
I know it's sounds newbie since i've just oppened the thread, but it literaly spend all day yesterday following guides and installing stuff on my pc, anyway glad it's apparently solved.
Anyone stuck on bootloader like i was that can't use xFSTK_ZE551ML, install the "WW_ZE55t1ML_2.20.40.194_20160713.raw" with flash tools, this was the only one that worked for me.
Just a warning to anyone who visits this thread --- If you have bootloader-- DO NOT use xFSTK -- xFSTK is to install a temp bootloader to bricked devices and only used if you have NO bootloader .
While trying to unlock bootloader I am getting Unknown error(900000) in flash tool. I have googled this issue and the solutions offered in it are not working(suggested to try old versions of flash tool, they wont even login). I have applied for unlocking before 20 days. Tool was showing 360hours wait at that time. attached the screenshot for reference,
I have tried unlocking at two different windows 7 PC, switching on and off - USB debugging. kindly suggest a solution for this.
Edit: Tool logins and detecting the device just fine, It checks the status of device, and in unlocking it goes upto 99% and shows unknown error
Sorry if this is the wrong thread.
Hello guys, I have a Redmi Note 5 (Global Version) with Snapdragon 636, and this phone is really amazing. I'd like however to unlock its booloader so I can install Pixel Experience on it, as I'd like to use other roms than MIUI. The issue is, well, I can't.
Something really strange happens: if I connect my phone via USB 2.0 to my computer, it is recognized as usual. It appears in Device Manager, is recognized by ADB, no problem. Then I reboot in fastboot mode and the device is still there. However, the EXACT moment I open Mi Unlock Tool, without clicking anything (Agree or logging in to my mi account) the phone is instantly disconnected and the "Press any key to shutdown" message appears on the top-left of my phone's screen.
Stuff I've tried:
- made sure OEM unlocking and USB debugging are on
- installed Mi Unlock tool in C:
- installed the ADB drivers in C:/Program Files
- disabled integrity checks from CMD
- installed and checked the MiUSBDriver umpteen times
- used 4 different versions of Mi Unlock Tool (1.0, 2.2, 2.3, and 3.3 - 1.0 halts at 50%, the other 3 won't detect my phone at all)
- made sure the device is bound to my Mi Account
I've tried using Hexerus' guide here (post #18) and everything seems to work fine, until step 6 when my phone instantly disconnects when opening Mi Unlock Tool.
Do you guys have any ideas? Thanks.
use usb 2.0 cable and port

Used USB 2.0, didn't work
Happened with me before, and I looked Google and found some solutions like installing the drivers again and using old miunlock tool and using different USB Socket however, none of theme worked,
Next day I opened the laptop to try again and suddenly it worked!
I didn't know what exactly fixed it
After the 720 hours period, I have spent literally weeks of trying to unlock my device's bootloader and what I would add is to switch between computers. I'm running Windows 10 on my room computer and all I had with MiUnlock were errors such as device disconnecting once in fastboot, "Couldn't unlock" messages, chinese characters... Until I decided to use my 2005 Windows 7 desktop and wow !, device unlocked at first try ! No need any other trick
just uninstall Previous drivers or use Windows 7 PC,with latest drivers of ADB ,i also faced same problem:angel:
Hi , Recently I purchased a Poco f3 and I am extremely Frustrated about to unlocking its bootloader. I will tell you Step By step what I did,
1. Mi Unlock Status (account added)
2. OEM unlocked checked/turned on
3. USB debugging checked /turned on
4. Waited more than 8 days
Problem started now!!
5. After waited 8 days, I Connect it with my computer
6. Software use to unlock it was official unlocking software
7. send me verification code after log in , tried 3 times , never show up any text's from xiaomi what so ever. Can not do unlocking until 24 hours again as already tried 3 times a day and no text messages.
8. Tried many ways , no result to get that code (extremely frustrating)
Very strange part:
9. Next day tried with 3rd party / official old version of "FASTBOOT to EDL Tool" , it taken my ID and password and logged in directly without verification OTP/ phone number verification.
10. I was so happy to saw that at least it is detected by my computer
11. Tried to bootloader unlock, "I have to wait another 148hours" Damn it already waited more than that.
12. Now , after that I tried to connected with my computer , but each time I am connected with USB cable (tried several cable both type C and 2.0 port) , it does not show up any phone on "Fastboot to EDL tool" anymore. Doesnt matter official or non official tool.
13. At least I want to see My phone is connecting with my computer properly and after waiting days and days, I dont want to mess these things again.
14. Xiaomi Mi Tool V2 (by Francesco Tescari) is detecting my phone.
MY QUESTION IS What I am missing here that is now allowing me or doesnt show up on the official unlocker tool ?? I tried every possible driver. This is the exact problem I faced last year and could not fixed. Did not have time to look in to it then.
Please help me to unlock my Bootloader. its a humble request.
Install all drivers until it detects your phone on v2 unlock tool.
Then use the official mi unlock tool and then unlock it.

Picture guide for unlock bootloader:
https://forum.xda-developers.com/t/4288121/post-85137959
Windows Driver issue is mentioned in Section 1 step 17.
Use official USB cable.
While your phone is under Fastboot mode, connect to PC with official USB cable and reboot your PC.
Make sure to login to your Xiamoi account on your phone and in the unlock tool.
More info (quick google) -> https://androidbiits.com/unlock-bootloader-poco-f3-m2012k11ag-easily/
and on your waiting periods time, dont re connect your mi account (at developers menu).
you press connect mi account, then it will reset your waiting time back to 168 hrs
