When i point the windows driver installer to the android_winuusb.inf file in usb_driver it says "The specified location does not contain information about your hardware" and i cant install those drivers.

Problem while unlocking E3 (D2202) Bootloader

I have installed Flashtool v9.23.1. I tried to unlock my phone (Sony Xperia E3 D2202) bootloader but i get an error saying there are no drivers. I tried to install them from the flashtool folders but there are multiple drivers.
I think the Common Drivers JDM-Platform is the correct one. But when I try to Install it it shows failed to install. How can i unlock my bootloader without using the Android SDK method. Pls Help!!

E6683 Flashtool allow to flash any FTF, but fail to flash any boot.img

My phone in the developer menu state that I have "Unlock Bootloader", same is confirmed by *#*#7378423#*#*
Still, flashtool and fastboot flash boot <kernel.img> , both return "Failed - command not allowed"
What I am missing ?
Other command from fastboot, like detect device and reboot are working, so ... I guess it is not a driver issue
Thanks

PS: On my old Z2 I was able to root with kingroot and then install dual recovery , but kingroot can't root my Z5 and I did try on Android 5 or 6 or 7 for Z5 Dual

Need help unlocking bootloader / using fastboot

Hello, my device is J7 2016 (SM-J710FQ) I installed twrp through odin and flashed custom ROMs but I didn't unlock the bootloader and I need to unlock now but since I use custom rom there is no "OEM Unlocking" option in developer options. I followed some guides and threads but I couldn't make it.
Here is what I did:
-Installed latest drivers for my phone
-Installed adb and fastboot
-Installed adb and fastboot drivers but I cannot change the driver. My phone is detected as "Samsung Mobile USB Composite Device" in fastboot and when I try to use the "Android Bootloader Interface" driver an incompatibility error occurs and driver doesn't change.
-My computer has Windows 10 in one disk, Mac OS in one disk and Windows 7 as virtual machine. I will install ubuntu alongside Mac OS.
Please help me to unlock bootloader / use fastboot

You already unlocked your bootloader by enabling the OEM Unlocking option. If you hadn't unlocked your bootloader, you wouldn't have flashed twrp and custom roms. Why do you want to reunlock it again?
