Hi guys,
Having received the mi Max 3 today (as a replacement for the old mi Max 3 that broke), I tried to unlock it, but I have a really weird problem.
I boot the device in fastboot mode. No problem so far.
Then I hook it up to the PC running Windows 10.
As soon as it is connected to PC, the display goes totally black with only some tiny caracters at the top left corner saying "Press any key to turn off device".
Anyone got that already ?
How do I solve this ?
That does not happen if the device is connected to my Linux powered computer... But that does not really help as the device can't be unlocked with Linux
WHY ? Why don't they just allow to use "fastboot oem unlock" to unlock the device ?
Regards.
In the programmer's options enable USB debugging and select the option Unlock OEM. start the phone in fastboot mode and connect to the computer having the miunlock program running

Hi,
Thanks for your answer.
I did that of course...
But still, as soon as I connect the phone to the computer in Fastboot mode : black display with only a tiny : "Press any key to shutdown"...
Any other idea ?
Regards.
You need to use a usb2 port instead of usb3

I already enabled OEM Unlock and USB Debugging in Developer options.
then I connected my LG G4 H811 to PC and confirmed MTP.
adb devices just shows:
List of devices attached
If I select USB charge instead of MTP, the adb devices shows:
List of devices attached:
LGH811***** offline
Looks like MTP mode adb cannot connect to H811 at all.
Does anyone know the reason? Really need to unlock bootloader and then root my phone.
Thanks

its beacause your mobile's Debugging didnt alowed that usb connection. when u type 'adb device' there should be a popup on your device asking to connect to pc. choose Allow. it will be online hen.
Thanks for the reply!
But there is no popup on the phone when I type "adb devices". The only popup I see is when I connect PC and phone with USB, a popup on phone asks me "Allow this computer to access your phone data?" I choose "Yes"
Any help will be much appreciated.

If all the checks boxes are ticked, try revoking USB debugging authorizations. Connect your device as MTP (try PTP as well) and try to adb devices again and see if you get the pop up on your phone. Last option would be to boot into recovery via button combo and reboot into the bootloader from there.

I tried all of your suggestions, none of them work.
PTP/USB charging mode, adb devices shows:
List of devices attached:
LGH811***** offline
MTP shown no device attached...
I did get into download mode (bootloader mode I think) - screen says Firmware Update, do not unplug the USB connection until the process is complete
Then I tried to run fastboot oem unlock, it stucks at
< waiting for device >
and there is no change on phone screen.
Any other ideas? I really need to root my H811. Appreciate any suggestions!
Change to PTP mode.

It sounds like your usb drivers ars not properly installed. I would try uninstalling and then reinstall. Did you happen to install LG Bridge?

Download mode is not the recovery. If you have TWRP installed as your recovery, power your phone off completely and disconnect it from the computer. Then press and hold volume down and power. Keep holding and when you see the LG screen, release only the power button and press and hold it quickly again (you should still be holding volume down). This'll take you to the factory reset screen, select yes twice and you should be taken to twrp. REMEMBER, ONLY DO THIS IF YOU HAVE TWRP INSTALLED!

I followed all steps in the thread you list. I am stuck at "adb devices" where I didn't see my phone is listed if I connect with MTP mode. For USB charge or PTP, I see devices but it is offline.
With this problem, I cannot get my phone reboot into bootloader mode and run oem unlock/twrp.

Did you tried revoking the usb auth?
http://forum.xda-developers.com/g4/development/unlock-bootloader-h811-20o-t3459285/post68630578
Do you receive a popup afterwards when connecting the usb cable?
PTP or usb charge should be fine.
What OS are you running?
.
I am using Window10 on my PC.
I made a tiny progress: I installed LG Bridge software and it updated LG driver on my PC. Now when I connect phone to PC with USB (of course I choose "ALLOW" for popup USB Connection Allow this computer to accept your phone data?). Now I see devices under MTP mode but it is still offline so I cannot boot it into bootloader mode. There is no popup when I run adb devices.
I tried revoke USB auth a couple of time, no luck
Finally I made it work!
The reason is adb I was using is too old
I changed to 1.0.31 then it works w/o any issue.
Thanks for the help all the way! I really appreciate your patience.

I am having a different problem, i get to all these step but when I type fastboot oem unlock it gets stuck at waiting for device no matter how long i let it sit. I know there is no problem with adb because it shows the device with the serial number, I just can't unlock the boot loader

Ok... Since I have no intention to root until Huawei pushes the Oreo and Facial Recognition updates, I have kept USB Debugging "OFF" and set Select USB Configuration to: Media Transfer Protocol (MTP)
Then, I attempted to do what you are trying to do... and it worked perfectly..
So.. Do This:
Step 1 Click on your windows icon and in the search bar type "CMD"
Step 2 Set USB Configuration to MTP.
Step 3 Again I had Debugging off.. you can try it with it on if you like.. either way turn off your device.
Step 4 Hold down the Vol-Down button while plugging your device into your USB cable connected to your computer.
Step 5 This will turn on your device and put you in Fastboot Mode.
Step 6 Now go to your ADB Command Line and type "fastboot devices"
You'll see it.....

Grab adb and fastboot from here Extract and open folder, hold shift, right click in the folder and open command prompt. Type 'fastboot devices' to verify that your device is connected. If all set, then type 'fastboot oem get_unlock_data' to get your string and follow the steps here

Make sure you're using oem cable, 2.0 usb port from the motherboard, not a hub port from the front of the pc. Also, make sure you're not putting the 'quotes' in the command.

i run.. .\adb devices for some reason my comp only runs it if you use .\ in front of the commands . then i use.... .\adb reboot bootloader ...the phone goes into bootloader .. then .\fastboot devices and it shows the serial, then .\fastboot oem get_unlock_codes and i was getting a cursor that stays until i close the program but with new link someone gave me for adb it says failed unknown command
1. T-mobile is unlockable
2. Turn on developer mode and Allow OEM unlock
3. On Windows PC, open adb via CMD. Connect your phone and type:
adb devies
You should allow authorisations on your phone.
4. Enter bootloader mode (maybe wait for the PC to recognize the phone). Type command:
fastboot oem get_unlock_data
5. Follow these links that others gave. Make sure Motorola and Google USB driver are installed.

Check usb port, cable, and adb/fastboot files. 95% of the trouble people have with flashing and/or fastboot commands can be attributed to one of those.
No that didn't work
I am trying for the first time to root my 7t pro McLaren, and I ran into a problem. When the boot loader is turned on, and I use fastboot devices, nothing happens. When I do adb devices with it powered on, it shows that its connected. I tried to use the oneplus usb driver update, and nothing happened. does anyone have any solutions? I have OEM unlocking turned on and SIM permantly unlocked. If it helps I'm running on windows 10.

Hi.
What you want to do exactly?
To Root open bootloader as first.
Developer options /Default usb configuration/ file transfer. Then check if pc "see" your device. fastboot fastboot devices. If visible then u are at home let's say
Make sure your USB port on the phone is clean using compressed air. Though if it works with ADB it should also work in bootloader

I was trying to just root it, but I found out what it was. someone sent me the drivers to update my device in manage devices.
When i try to enter fastboot i am not getting the logo but just the word "fastboot". My poco f3 works perfectly but will not enter the fastboot mode with the logo. When i connect to the pc it is not recognised in this mode. I would be grateful if anyone can advise how to get it back to normal.

New fastboot logo is the orange FASTBOOT word. So it is already normal. If it's not recognized it may be a problem with drivers, usb cable, debug authorization/permissions.

Hi,
I have had my F3 for 13 months and Fastboot and windows can still be temperamental, my PC has 10+ usb sockets.
As bozinsky73 Suggested installing the correct drivers and maybe a different USB-C lead might help, you could try running MiFlash and then select the drivers tab and then Install, as some XDA users have had success with this.
I have tried 3 different (Aliexpress) Silicone coated leads and these cause my PC to flag up "unknown device" when in FASTBOOT, i also have 2 leads that look like the most cheapest ones out there and these work OK, even thou some times i still have to switch to another USB socket on my PC.
I run 3 different versions of windows on 3 different partitions that run, Win 7, Win 10 and Win 11 and i am still faced with the same issue regardless of the windows version.
I hope you sort it.
Thanks for the replies and solved it with a new cable. I was using the cable that came with the phone but obviously must have damage somewhere. Thanks anyway.
