Seems you have selected don't ask next time feature. If you can see MTP on pc then USB debugging should be working. Try and And see if your device detected

How to get fastboot to recognize my K4 Note A7010a48

I am not being able to unlock my K4 Note no matter and I will have to admit it's so frustrating. I am not new to unlocking and modding party but i just cannot get to have this done!
I downgraded from S230 to s218 & now on s219. I am able to get adb to recognize my device but not fastboot. Thus I am unable to unlock bootloader!
When I type in " adb reboot bootloader" or click on the "unlock_recovery.bat" file provided, I get booted into a dark screen where "fastboot" is written at the bottom left & the command prompt window says < waiting for device> & I am stuck there until I reboot my phone.
i have been seeking an answer to this since the last 3 days but am yet to find one
This is problem with the driver, I too had problem. Do enable usb debugging, connect to PC, it will ask permission in phone, give ok. Now a lenovo folder will appear on PC, click on usb driver installation, done.
Now try adb and fastboot device will detect.. Also i hope u enabled oem unlock in usb debugging
Hit Thanks if it helped!!!
Same problem
I am also facing the same problem
Please provide solution if you found one

Hey, Bro, I found the solution
1. Goto C:/Windows/INF and search for wpdmtp.inf & right click and install it.
2. Turn on safe mode on your phone and then connect it to PC then remove safe mode.

Brother i think you have missed something. Open developer option and ON USB Debugging. If you connect your phone with PC then by default it will be connected as a charger you have to change it to Transfer Files.
Swipe down your notification pannel and there is a notification of USB touch that and new popup will open to phone and then change it to Transfer Files and you are done. Now you can transfer files.
I uploaded some screenshots to help you better.
Hit like if you think i helped you.

Goto device manager in pc, under portable devices you will find MTP device. Right click and uninstall the driver. A new icon with exclamation mark should appear. Double click on it, installation wizard pops up then click on ' browse my computer for drivers' then you find mtp drivers now install MTP USB Device... Not MTP Device. Just reconnect the phone. And the job is done.

My OP5 cant connect to laptop (Worked before)

Hi
i cant connect my OP5 ( two days ago it worked) to my laptop
changed cables and usb ports with not success
this is what i am getting
"Currently, this hardware device is not connected to the computer. (Code 45)"
and after this i dont see even the yellow mark on the device manager
please assist
thanks
Sounds to me like an driver issue. Just install the platform tools again, reboot pc and connect your phone again. Or enable ADB and USB debugging again in Developers Options and reboot device.
Hi
How do i enable adb on the phone ?
Usb debug i enabled but it didnt helped

Windows 10 won't Recognize my Phone in Fastboot Mode but ADB Is working

Hey Guys,
i tried to Root my Moto E4 but Unfortunally i cant get Fastboot to work under Windows 10 Home 64 Bit on Both my Notebook and my PC. I installed The Motorola Device Manager (Since it comes with drivers) and installed ADB and Fastboot but once i Reboot into Fastboot Mode it wont Recognize it for flashing. The CMD Just Says Waiting for Device. I have expierience with Rooting other Phones but i never had this much Trouble getting Fastboot to work properly. Would be awesome if u could show me a Solution to this since i really want a Custom Rom.

There's no trick, it just works. I have Windows 10 64 bit as well and no issues. Maybe you need to update your platform tools (adb and fastboot). Using old ones can be a problem.
What command are you issuing? Just fastboot devices ?
Make sure you're not using a USB 3.0 port on your computer.

Few other thoughts:
- try a different cable; a cable that works for charging and adb communication may not work with fastboot
- avoid external hubs if possible
- be sure to reboot both devices after switching drivers if communication isn't immediately established

When you say you booted to fastboot what do you mean ?
Did use adb and your phone was recognized and then you issued adb command or what method are you using ....
You need to ensure you establish USB debugging connection first & grant authorization ...once link with authorization has been established run adb ...from adb check if recognized run command to boot to fastboot
So start from the top && go down
ARE YOU CERTAIN YOU USED CORRECT METHOD TO TURN OFF DRIVER VERIFICATION ON WINDOWS 10 && YOUR DRIVER ACTUALLY INSTALLED
Last noteworthy point ... when unlocking my motoE4 I had to boot to bootloader ONLY to use fastboot NOT "FASTBOOT"
Hold power + volume button
Excellent troubleshooting from our community. OP has not come back yet to confirm, ask another question, or simply a thanks. (Maybe he got it) Hopefully he gets it sorted.
Maybe the junior members underestimate just how quick and helpful our little community can be.
@Marc_Xperia Do not forget to install AndroidBootloaderInterface Driver Software. *android_winusb.inf*
Thats what my Problem is. I installed the Latest Android Studio, i have gone to SDK Manager. Installed the Android 7.1 Files and USB Drivers and this happens everytime i want to unlock my BL. And yes i disabled Driver Signing on Windows 10. I call it Fastboot Mode since im Used to Xperias so im Sorry i confused anyone.

When you authorize your adb connection do you tick or select always allow connections from this device ...the fact that your device is listed as *unauthorised* is a clear indication in your previous attempts you didn't authorize to "allways allow connections" from this device
#result _when you reboot authorization is revoked
Enter bootloader mode the old skool way using your buttons..
# MAKE SURE TO SELECT "ALLOW OEM UNLOCK OPTION IN DEVELOPS settings
1.AUTHORIZE TO "ALWAYS ALLOW CONNECTIONS FROM THIS DEVICE"
2.enter bootloader using hardware keys
3.plug in usb
4.run fastboot devices to force fastboot to start deamon ...
5.once fastboot can see your device run oem unlock
6.DO NOT USE USB 3 port so try different USB ports on pc
7. Alternatively use a live USB of Ubuntu minimal to do the job
--- doesn't seem like driver problem if adb can see your device
See if that works

I did all of that. Next Problem when i boot the device with Vol Down + Power and select meta mode. I will get only the Motorola Logo or a Normal Reboot into System. I set everything up in Developer Settings. Enabled Debugging and Allow Bootloader Unlock.

Why select meta mode ? When you are in bootloader you use your volume keys to navigate between meta, recovery& factory reset & meta and you use your power key to select different modes ...what do you want to do in meta mode ?
When you are in bootloader you are essentially in fastboot mode too so it isn't necessary to choose any of the other options unless you are trying to get into recovery which is pointless if you haven't flashed custom recovery yet ..
I Succeded. I Booted into Bootloader with ADB and took a look at Device Manager to install the Driver Properly.
i followed this guide https://forum.xda-developers.com/moto-e4/how-to/guide-unlock-moto-e4-bootloader-unique-t3654275.
Thank you for all of your Replys.

No it doesn't. That's an error in magisk manager when you hide the manager app itself. Just use a different safetynet checker app if you want to check safetynet.
Why are you posting this stuff in this thread?
