Need Help Unlocking Bootloader

I've been trying to get a ROM on my nexus 6, but as I go to unlock the bootloader, I enable usb debugging but get no prompt to authorize my computer's RSA Fingerprint. Any Ideas would be helpful. I've Tried all different combinations of connections (MTP+USB Debugging, etc.), and it still will not prompt me to authorize it. Thanks.

Have you tried Nexus Root Toolkit? I used that back in January to unlock and root my Nexus 6.

Reboot the device. Set switches for USB debug and bootloader unlock. Plug in phone. If don't work there a driver problem. If see your drive on PC don't worry about it. If it sees adb and/or fastboot don't worry about it. Don't use toolkit unless already know how to fastboot. If it screws up you are screwed cause don't know what happened.

For those who happen across this thread but cannot be bothered to read the link above, here is a little note. You do NOT need USB Debugging to unlock the bootloader. USB Debugging is an ANDROID setting, for use in Android. It has no effect on what happens to USB connections made in the bootloader or recovery.
EDIT> Actually that thread says you do need it. You do not.

For that thread no you do not need it if boot into the bootloader manually. For others that use the adb reboot bootloader command you will need it.

I know you said you already did, but uninstall every android driver you find on your PC. Then connect your nexus, while booted to android and let drivers install. Then disconnect, boot your nexus into bootloader, and reconnect again to install fastboot drivers.

Can't flash TWRP

Hi. I decided to flash my Honor 3c with Cyanogenmod 12.1. My problem is that i need TWRP (now I have CWM) but i can't flash it to my device. I try to do it by SP Flash Tool, but after i connect my turned off device, I get this error:
BROM ERROR : S_BROM_DOWNLOAD_DA_FAIL (0x7D4)
[H/W] Fail to download DA to baseband chip's internal SRAM!
[HINT]: 1. There's an cable communication problem between FlashTool and BootROM. 2. Target might be shutdown unexpectedly or target lost power supply.
[ACTION] 1. Try again. 2. Proceed H/W checking in download cable and target side com port. 3. Monitor if power-drop occured in target side.

Is your phone in bootloader mode? Hold Vol down+power to enter fastboot mode and then connect your phone to PC.
If you are already doing that or the problem still persists and have an unlocked bootloader(which I am sure you have), try to flash twrp manually.

When I do it, my phone just turns on normally.
How can I check if I have unlocked bootloader? I have unlocked it about 1 year ago, but I did full wipe yesterday.

Vol down+power should boot into fastboot. Turn off the phone, hold both until honor logo shows up, let go of power but hold vol down for about 5 sec more.
If still the same, Turn off your phone, connect USB cable to phone, hold Vol down and connect the cable to computer. It should boot into bootloader now.
If it can not boot into bootloader still, the last is to try adb but that is a bit lengthy.
In bootloader mode, it will be written on phone screen in red whether phone is locked, unlocked or relocked.
Wipe does not effect bootloader status so it's still unlocked imo.

At least it should say, phone locked. Saying nothing is a phenomenon i never heard before but I usually go for newer versions. May be that's the case.
Anyways use adb to fire this command
Fastboot OEM device-info
To be sure if its locked or not.
To setup adb, download and install latest Android SDK, run the program and only download platform-tools.
Your phone is international variant and it came with locked bootloader, I am sure sp tools unlocked it coz otherwise CWM could not be flashed.
Right click platform-tools folder and select run command prompt window here and type the above command
If the bootloader is unlocked (it will tell you if it is), copy the twrp image to platform-tools folder and rename it to twrp.img and fire this command
Fastboot flash recovery twrp.img
And try to reboot into recovery after disconnecting from pc and simultaneously holding power+ Vol up.

edit: nevermind, i forghot about something...

You dont have your phone drivers installed. Google Huawei USB drivers and install them or use hisuite to install drivers for your phone.
After driver installation, do the same process again.
My bad. I assumed you would have drivers already installed

Hisuite is the best option. Even if that does not work (there is a chance of that), Google Kouch's universal drivers and install those.
May have to manually install dribers if nothing works.

I installed Hisuite and connected my phone. Windows have downloaded drivers automatically. And still the same...
But I forgot to tell you that when I connecting my switched off phone, my pc says "USB Device Not Recognized" (or something like that, I dont have english version of windows). Everything is ok when my phone is switched on...
This phone is cursed. I try to give up and stay on my current ROM, so I installed Nova Launcher, but setting it as default doesn't work :/
Thanks for trying to help me anyway.

I was awake just for your post. I think I got the problem. You need fastboot drivers imo but I would have to read a bit before I can suggest how to go about it.
Am busy tomorrow but will try to get back to you in the evening (GMT+5 time zone).
Can never be 100% sure but still I am confident, your problem has a solution. Just bear with me a day or two

Boot into recovery mode, no matter on which recovery are you on, and execute this command:
Code:
adb devices
And see the output, if it says something like:
Code:
**some_number** recovery
then it means there is no problem in the detection of your device by PC, if it does not, then check if the micro USB socket in the device is in good condition.
And I must ask: Are you able to do any operations on device via PC after connecting it?

PC will not detect Mi Mix

Mix

MIUI Version: Miui Global 9.2 | Stable 9.2.1.0 (NAHMIEK)
kernel: 3.18.31 perf-g0bf156d-01070-g4aac0b4a
Phone came unlocked from seller HongKong Goldway on Aliexpress.
I have tried to download the usb drivers for my laptop which is on windows 10 and a PC running windows 7 and did that update driver thing and tried to use the downloaded winusb_inf file. I've also tried going into windows INF folder and right clicking that wdptmp.inf file and trying "install".
The laptop says Unknown USB device ( Device Descriptor Request Failed) and the PC says Unknown Device. Both are under the USB section on Device Manager
I installed ADB Fastboot tools, turned the phone off and held power + vol down to go into "Fastboot" where it loads a white bunny with a green russian hat holding cords behind a green android robot. Fastboot on the computer doesn't detect any devices.
I also tried Mi Suite and nothing detects. I am using the original usb type C cord and I also tried 3 different usb Type C cords.
Any help guys?? (Also I can't find any update app icon anymore...is that new?)
I want to install TWRP and root so i can do that performance tweak for the mix. and load up a custom rom.

Hi thanks for the reply,
Is that the program that has the "RESTESTING" and "INSTALL" button/options? If so. I've tried clicking install and it says its finished. If this is the same program were talking about, it didn't do anything to help detect the phone.

Sounding like you might have a vendor ROM installed, you should follow the guide in the guide's section, follow the guide for installing twrp with vendor ROM. The unlocked bootloader is a sure sign the vendor installed their own ROM.

No follow the guide for the correct install of driver's, disable driver signature in windows 10.
http://en.miui.com/thread-345974-1-1.html#post_6279092
There are 1000s of people on this forum who have done the same thing you are trying to do. So basically you are trying to get China dev ROM installed through miflash, then your PC will recognize it then you can install the rest after.
Search vendor ROM mi mix, even if it isn't vendor ROM sounds like you are still going to follow the same guide.
Have you tried another PC? Don't see anyone else complaining about not detected

i have tried 2 and 3, nothing. method 1's steps didnt really make any sense to me so i didnt do that one.
im dumbfounded because im reading posts on XDA and MIUI forums and theres like 30% of mi mix owners that never found a solution to this while the other portion did easily. I have no idea what I could be doing wrong and I'm starting to think it's the phone and not my laptop. I also found out that when i go into fastboot mode on my mix, it only stays in fastboot mode for like 30 seconds and then ejects itself out of fastboot mode (im not sure if this is normal)
Ive also tried to download older official china roms and tried updating them through the mix's updater option. nothing. what in the hell is going on here?!??!?!

Hey thanks for the reply.
Do you see picture 1 you uploaded, where its device manager and you can see Portable Devices and there you have that One A2001 device that shows up?
I don't have ANYTHING that pops up under portable devices or portable storage.
Mine only has a notification under the USB serial bus controllers. Mine says only this
Now, I know what you mean by trying to install the MTP USB Device, except you can't do that when you have this kind of USB error because it doesn't even detect a device to even update a driver to MTP.
If you read back you'll see that I have tried installing USB drivers before, I've also used the MiFlash tool to install drivers through there. Still nothing. If someone can find a fix I'll paypal them a few bucks for their trouble because I seriously don't know what to do from here. I've searched many forum posts on here, miui forums, reddit and everyone seems to at least have something detect in their Device Manager as a device. OR some people are able to detect their device in ADB boot but mine doesn't and mine also can only stay in fastboot for 30 seconds before it kicks itself out.
I also don't believe I have a vendor rom because it only has 4 numbers despite coming in the mail already with an unlocked bootloadeder.

when i uncheck compatible hardware box (there is no mtp as far as i looked in the options)
I believe yours gives you the MTP option because your computer picked it up as a device. Whereas mine is having some kind of USB error and doesn't know wtf is plugged in? The thing is, it will detect my Redmi Note 4 Global with no problem... so

Damm.
IDK maybe there is a problem with your charging port.
You can try another thing, If you have another phone with a USB type C port and you have a USB type C to USB type C charging cable, then connect these 2 phone and try transferring files from one phone the to other (Did it with my phone and my friend's Nexus 5X).

Question Mi unlock/USB keeps connecting/disconnecting

I was wondering if anyone experience the same.
I want to unlock my bootloader but everything I connect my phone (in fastboot) to PC I hear windows connecting and 2 seconds after that disconnecting in loop.
Mi unlock therefore doesn't see my phone, and in device manager you see "Android" appearing and disappearing.
I used the original USB cable.
I've installed mtk drivers as well as the Xiaomi USB drivers.
It's only in fastboot, normal mtp mode does work well.
But I can't unlock my bootloader this way.
Please help.

where did you find the drivers? I am looking for them

Found it on xiaomitools website. (Googled for Xiaomi mtk drivers)

I had the same problem and how I fixed it was just going into device manager in windows and installed my drivers manually from there and now the phone is detected as an "Android adb interface" when it's in fastboot.

I just solved the problem. You have to disable signature enforcement and then download the driver installer from here (Pick Redmi Note 10S and then choose the Mediatek Driver or click here). Follow the guidelines and that should be it!

Question Windows 10 drivers for fastboot

My rednote is not being recognised by my Win10 PC when in fastboot mode. ADB is fine but the moment it boots into fastboot, it disappears. I've tried numerous different drivers now, and restarted the PC to disable driver signature but nothing seems to work. Fastboot mode is recognised when the phone is connected to my linux laptop.
Is there a trick to it? Or a guaranteed set of drivers that work both adb and fastboot?
I want to unlock my phone but cannot run the official MiUnlock tool.

And I've viewed a number of them. Could you link to one that actually works?
Seriously, I'm not stupid. I've tried a number of supposed solutions. I'm not a Windows geek, it's true, but I'm happily techie on UNIX platforms. Maybe this is something other than the actual driver. I'm more than happy to learn.,

For those who have problems installing , you need to create a new folder called "Desktop" in C:/Users/*Your user*

This is exactly my problem on Redmi note 11S. I already tried a lot of drivers and tutorials and still no succes. In linux fastboot works.
PS: Les Girauds, you can unlock bootloader by mtkclient (linux), not just via official tool (Mi unlock). I already did it.

Thanks, might give that a go.
I tried another UNIX based unlock solution yesterday (a python prog from GitHub) and whilst it didn't work cleanly (nor successfully unlock the device) I did see in the garbled error message returned about having to wait 121 hours. So maybe the phone will be successfully unlocked on Tuesday!

Thanks, that's worked. The Yt video didn't show for me so I copied it's URL and opened in a separate browser window. The video went through the process for Win 11 but I guess it's the same for Win10 (my system), and it worked so that's OK. Weird thing is, it was only an install of the generic adb drivers which I'd installed previously anyway, and had been using for some time, doing updates on my Lenovo tablet etc. So they were there and working once upon a time. I can only assume that the process of installing the MiUnlock screwed them up somehow.
@Magic Cucumber - it might be worth you simply reinstalling the standard adb platform tools, It might give you back fastboot access

Thank you. It worked. The MIUnlock said I had to wait but mtkclient did it immediately.
Now I'm going to flash a custom ROM, and maybe twrp, just have a device I'm happier with. Xiaomi phones maybe good value but I don't like the stock software.
