[SOLVED] Windows doesn't detect fastboot. - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Alright, so I have my phone completely setup for oem unlock, I think it's a problem with windows.
What happens:
When I connect my device(on) it connects and everything is fine, even adb works, likes I can do adb devices and it shows my phone, BUT when I reboot to fastboot and try to do the same with fastboot devices it outputs nothing. Also in device manager it show a yellow warning mark, it tells me to press the "Update Driver" button, but if I press it says that it doesn't have any drivers for it. Are there like seperate drivers for adb and fastboot online? If so link me the fastboot drivers, thanks in advance.

Well this is awkward. I managed to solve this.
For anyone in the future if they have the same problem, I followed this video.

Please explain what you have done exactly : Video's can disappear after some time!
And not all of us are great fans of YouTube...

Guess what? I did everything like this guy showed in the video, still no success. Doogee S68 Pro is just cursed. Lucky you guys with Samsung, OnePlus, Xiaomi, etc...

@Cheaterboy
Let's start with telling us what is wrong exactly and what you have tried so far ?!
DooGee phones are AWESOME!!!

Amazfit - boot into fastboot directly

Hi,
I finally found the real method to boot our Amazfit watch into fastboot. It is difficult to success at any time, but you should be able to boot fastboot directly after some try.
Here is the procedure : (I've made a video : https://www.youtube.com/watch?v=ZlXoeq30vM0 )
When you try, I advice to put the watch in its charging base, the usb Cable connected to the base, but not on the PC.
Here are the steps to go in fastboot mode :
1) press the power button 2 seconds
2) release the button et repress it again without releasing it
3) when the screen of the watch switch off, plug the usb cable.
4) when the screen turn on, count from 1 to 4. At 4 release the power button. You are now in fastboot.
If it fails, try again. It is a little difficult.
Hope this helps.

OMG!
edit:
how the hell do i get those files inside with only wastboot mode ... FFS
2nd edit: @Neuer_User, I have the pulled mmcblk0p7 on the storage, is there any possible way of pushing it back into the system via fastboot?
Guys, that is so great! And @kiralex1995 deserves highest thanks for his finding! We need to get a stickied post for this!!
@1immortal: I'll prepare instructions for you. You will need a modified boot image and then boot this. Then you can flash system from there!
Accidentally opened fastboot with a different method.
My device didn't show up under Windows 7, after I installed adb and fastboot drivers.
So with device connected to usb I typed adb kill-server, then adb start-server and adb wait-for-device then I switched it on and off... tadaa fastboot. See picture with command lines.

Interesting. See if you can make it reproducable. That would be great!

I wrote some unbricking instructions and a flash script to recover bricked watches with @kiralex1995 method of entering fastboot.
Hope, it helps recover the small number of watches known to be bricked through flashing.

You're welcome
@kiralex1995 , Thanks a Gazillion !!!
it worked and with @Neuer_User help, the watch came back to life !!!
My fastboot method was reproducable on a different machine on Windows 10 . Needed 2 attempts. Seems a question of timing. Right before it happens, the computer makes the notification sound for 'new usb device detected'.

maybe you need to explain a little bit more detailed? is the watch running and completely booted when you connect to usb and type those adb commands or is it switched off? when you turn it on, how fast do you turn it off? i didn't get it yet. please explain a bit more.

It is interesting. Does it work with out th.e adb kill-server and adb start-server commands? I do not see, how they could be involved...
The adb wait-for-server might be the key. So, when the watch is started, there is some USB communication on-going. I'd love to do some testing on that. Will do that for sure, when I get the development watch
I' m not near my computer, so I can't do more tests now.
As I wrote in my first post, it wasn't my intention to open fastboot, when it accindentally happened for the first time.
The kill and start commands were given, because my Windows 7 machine pretended not to see the watch in adb (only as usb), and I thought, maybe it's detected, when I turn it on while adb is waiting for device and the usb notification 'kicks in'.
But nothing happened, so I pushed the button, to turn the watch off again.
To my surprise the result was fastboot.
I repeated the same steps today on my Windows 10 computer that always detects the watch in adb and it opened fastboot again.
Could you specify for which build or version you tried this? I (unfortunately) had the update to 1.3.5 and there seems to be no way to enter fastboot. It also is not recognised as an adb device
I have a amazfit pace but he is stucked on a update screen and when I try entring in fast boot mode he doesn´t enter and goes to update again and don´t conclude that. What can I do?
Did anybody managed to get Amazfit 2 (stratos) to fastboot using this method? thx...
EDIT: Yes, I can confirm it works! However it is really kind of tricky. Embrace yourselves!
Many thanks to you guys for finding this out, you are the best!
Thanks.

can confirm that this method (sort of) works for stratos as well.
i guess the important part is the 4 seconds after the light goes on. i have done it in like the 8th try.
i guess pulling the usb cable and reattaching it is not really required...
Hello my device is waiting for the logo, it is not opening.

Hi all together,
yes I can confirm that plugging the cable is not neccessary. Went back to stock yesterday. Got into fastboot on first try.
I'm trying that on an actual Stratos watch way longer than 40 minutes - maybe you could help me: I have an "A1619"-model with firmware 2.3.5.0. Same for other Stratos users?
Unlike in the linked video, when I'm at step #4, the "A."-logo appears after about 2 seconds again, so if I release the power button after 4, it's already visible and bootup goes on as normal. Did you notice the same behavior with the "A."-logo before accessing fastboot?

Fastboot can't detect my coolpad cool 1 dual. Please help.

I am facing an issue. I want to flash twrp into my coolpad cool 1 dual but my fastboot can't detect my device. ADB is able to detect it but as soon as I run the command "adb reboot bootloader" to boot my phone into fastboot mode fastboot doesn't detect my device any more.. I have tried updating the "android bootloader interface", " android adb interface" drivers but still nothing does work.. Tried a various types of usb driver available at xda in various threads but none work. What to do now? Please give me a solution to install twrp~
I got the same problem here, I installed a lot of several drivers and nothing. I keep surfing on the web trying to find a solution. If i get one I will notice you.

Samsung Drivers Won't Work When In Fastboot Mode

First of all, I would like to point out that the XDA Developers website has made this problem harder than it needed to be. This post is originally from Stack Exchange, but people said I would have more luck here with this problem. But every little thing I do it a problem. Try to use a proxy on the website? Nope. Try to post this in the Samsung Galaxy S7 section, where it's SUPPOSED to be? Nope. I know it's all to prevent spam, but I mean come on. Be a little lenient here. Anyways, I'm done with my rant. Back to the post.
I have made the mistake of trying to root my phone. Which is fine, but it's a lot more complicated than I thought it was, but since I have asperger's, once I start something, I feel like I have to finish it.
I have a Samsung Galaxy S7 (SM-G930U) with Sprint. I've heard that these phones are EXTREMELY difficult to root. Some even call it impossible. But I can at least try.
I ended up getting tunneled down a endless loop of tasks to complete before I actually root my phone, for preparation. One of the things I must complete is I have to install a TWRP Recovery Image in case of failure. But in order to do that, I have to unblock the bootloader.
To do this, I am using Platform Tools, with includes ADB (Android Debugging Bridge), and Fastboot. I connect my phone to my PC via USB cable, open the CMD, and type:
adb reboot bootloader
Once I do this, my phone reboots into the bootloader, just like it should. Normally, the next step I would take would be to type in:
fastboot oem unlock
When I do this, I am left with the message:
< waiting for any device >
I'm assuming that means that it's not detecting my phone at all. It's odd though, because it was able to detect my device perfectly fine whenever my phone was booted normally, but when I go into the bootloader, it doesn't detect my phone anymore.
After hours of searching around the internet, I found that a potential problem could be the drivers of my phone that are installed on my PC.
Sure enough, if I open up the Device Manager, when in the bootloader, under Universal Serial Bus Controllers, I found the driver "SAMSUNG Mobile USB CDC Composite Device", with a little yellow arrow next to it on the icon.
If I double-click on the entry, in the "Device Status" box, it will say:
This device cannot start. (Code 10)
An invalid parameter was passed to a service or function.
Code 10 means that Windows is saying "There's a problem, but I don't know what." And well, I'm stumped by this.
The drivers work perfectly fine if I'm booted normally, which is why I'm confused. In the meantime, I'll continue my rampage across the internet for a solution to this problem that actually WORKS.
If you're wondering, I using Windows 10.

I am having similar problems with my Galaxy S7. In order to make any significant changes, the bootloader MUST be unlocked FIRST. Hence, the dilemma, if you can't make changes without an unlocked bootloader, and you can't unlock the bootloader, what can be done.
As far as I know Samsung devices simply don't have no fastboot support. Refer to Odin flashing tool instead.

Need help unlocking bootloader

I've tried several times to unlock the bootloader and it will not respond to any commands once in fastboot mode. I've tried to follow this guide https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/ but whenever I type "fastboot oem unlock" it just says "waiting for any device" and nothing happens. I have usb debugging enabled and oem unlocking on so I don't know what I'm doing wrong. I have the platform tools from Google installed. I can run adb and type "adb reboot bootloader" and it responds, but after that, no fastboot commands work. I mainly just wanted to root so I could restore my apps and data via Titanium Backup. Is there a temp root solution I can use? Or has anyone else experienced this?
Let me know if you need more info. Hopefully this is an easy one.

I feel like it's something simple I'm missing. I've never had trouble figuring this stuff out. I've been rocking an HTC M8 on VenomRom since forever ago so it was time for an upgrade. I've looked at several different guides, but some of them seem to be incomplete. Like the guide at the official TWRP page says to power off the phone. Then it says to hold volume up to go into fastboot mode. I tried following those instructions to a T, but that didn't actually do anything. It doesn't say where to put the twrp.img file, it just says to run the command to boot the .img. Getting into fastboot isn't a problem. It's that no matter what I do once it's in fastboot, I just get "waiting for any device". I've tried the OnePlus6t Manager because I thought maybe I needed a one-click method. But again, it gets to fastboot and goes nowhere from there.

Just my 2 cents I'm not an expert but it Might be your drivers or when you installed adb did you do it with administrator rights? The first time tried I couldn't get it to work it wasn't detecting the device in fastboot so I reinstalled adb and then it worked
I just rooted mines today but I went off a YouTube video I looked up and they had everything you needed to download in the description. Took about ten minutes ? I'm not sure if I can put a link on here

I've done that also. Developer options are enabled, USB debugging, and OEM unlocking. Are there newer drivers I need? But if that was an issue, it wouldn't allow me to do "adb reboot bootloader". It'll reboot to fastboot mode, but after typing "fastboot oem unlock" it just says waiting for any device.

you need to be careful in fastboot. One wrong command can lead to a catastrophe.
I used the adb installer from the same video. Once you unzip it. It's an .exe file which I granted administrator rights to install... it installs adb and drivers and it worked for me
That's the video and did it to a T
Another thing don't use power shell use command

Still getting nowhere. I thought my problem was that I didn't intall the drivers as administrator. So I did it again, following this video https://www.youtube.com/watch?v=B-XZy27wy5o When I reboot into bootloader, I type "fastboot devices" and it just goes right back to the command prompt. Nothing happens. I guess I'm going to try the old fashioned computer restart and see what happens. If all else fails, I can unplug it from the wall and blow on it, lol.
I swear, I've never been this simple before.

I was thinking that maybe the latest OTA broke the bootloader unlock process, but someone else in this thread said they just unlocked theirs. I don't understand what the issues is. I've followed this video so closely I could re-enact it in my sleep.
Got it! I had two sets of drivers installed so I uninstalled both and it finally recognized my phone in fastboot. My old drivers from my m8 from 2014 were probably interfering with it. I knew it was something simple. I feel like Carl in Sling Blade when they bring him the lawn mower engine and he says "ain't got no gas in it, mmhmmm".
Nice! For a noob I wasn't too far off lol it just had to be one of those two issues
Enjoy happy rooting ?

Moto G5 Plus "bricked" after update.

Hello! I don't know if there might a be a solution for this problem, we've tried many stuff that's been posted here on the forums but ended up in the same results, so no luck. My friend's Moto G5 Plus "bricked" itself while updating to Oreo some time ago, wasn't rooted or anything, bootloader wasn't unlocked either. We can access the recovery menu with "power + vol+", but any option we try to use ends up with the message "Failed to pass validation, backup to fastboot". Some of the solutions I've tried require the bootloader to be unlocked, but I haven't been able to unlock it since my friend never checked the "Allow OEM unlock" option. He took the phone to the official service but they said they couldn't do anything and wanted to sell him a new phone. Any help is appreciated. Thanks in advance!

Would be helpful to know what exactly you've done to rescue that device.
For example, did you try to wipe the complete device and fastboot flash the latest signed Oreo firmware?
Is the device recognised by a PC?
What about using Lenovo Motorola Smart Assistant?

Hey! From what he told me, at first he was able to access the recovery menu, when then little Android with the red mark shows up, then he used the Smart Assistant and after that he gets the validation error message that I mentioned. I suppose the Smart Assistant made things worse? The device was initially recognised by the PC, but now it isn't. We tried to flash the stock firmware and unlock the bootloader but we didn't have any luck either. Since the PC didn't recognized it anymore we tried a few things to make it work but ended up giving up.

So you can't get to the screen with the dead android (fastboot mode) or recovery with the key combination (power and vol down/power and vol up)? You should be able to get there and check the connection by typing
fastboot devices
or
adb devices
Is the battery full enough to start?
Do you see the device in Windows devices manager?
PC should recognise it at very worst, as qhsusb_bulk. Your PC must be in test mode, and then when you connect look in device manager, under usb devices, and a hard bricked phone will show as qhsusb_bulk. Anything else, you should be able to communicate with ADB/fastboot, as Wolfcity stated. If it does show as qhsusb_bulk, you will need to use vaches' blankflash to recover the unit.

I tried to attach a couple of screenshots but I get the "bad request" message here. Anyways, when we do a normal boot we get the validation error message and we are sent directly to fastboot menu, but there we cannot choose any options because all of them lead to the error message again.
It's been a couple of weeks now but the last time we tried doing something, the device wasn't showing up in device administrator nor being recognized by adb.
As regards to the battery, we've left it charge up for some hours, so I guess that's not a problem, although we cannot see the percentage.

Your PC must be in test mode, and then when you connect look in device manager, under usb devices, and a hard bricked phone will show as qhsusb_bulk. Anything else, you should be able to communicate with ADB/fastboot, as Wolfcity stated. If it does show as qhsusb_bulk, you will need to use vaches' blankflash to recover the unit.

I'll tell him to check if it shows up as qhsusb_bulk and update here. Could you explain a bit more or link to a thread about vache's blankflash? What is it exactly?

To get PC in test mode
Code:
Here is how to turn on or off the Test Mode feature in Windows 10.
IMPORTANT: Please remember that turning off the Test Mode feature may force the program/driver which is not digitally signed stop working.
Step 1: Open Command Prompt as administrator. To do so, type CMD in Start menu search to see Command Prompt in the search result. Right-click on Command Prompt entry and then click Run as administrator option. Click Yes button when you see the User Account Control screen.
Step 2: At the Command Prompt window, execute the following commands:
To enable the Test Mode:
Bcdedit.exe -set TESTSIGNING ON
To disable the Test Mode:
Bcdedit.exe -set TESTSIGNING OFF
If the above command didn’t work, this one must work:
Bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
Bcdedit.exe -set TESTSIGNING OFF
You may exit the Command Prompt now.

Update: The PC detects the phone as Android Device > Mot Composite ADB Interface.
But once in adb, adb devices isn't working. It doesn't recognize the device.

It is recognizing the device, " Mot Composite ADB Interface" is correct.How about
Code:
fastboot devices
? It should show the device #. ADB doesn't always show devices.

Yes! Fastboot devices shows the device! So now we have to procede with the flashblank.zip and all that from the other post right? Also sorry for the late reply, I've been pretty busy these past days so I left him with all the work.
