Hello, i need help unlocking the bootloader of my Wiko Y50, i searched a lot but i dont found nothing, if anyone can help me please tell,
The problem is:
When i use the command adb reboot bootloader, it works, when i use fastboot devices, my device is shown in the list, but when i use the command fastboot flashing unlock, it gets stuck in a flashing _ ,
Hi, @Alfred13, welcome ro /e/Land !
What are you expecting Trying to unlock the bootloader of a Wiko device ?
Hi @Alfred13 according to this page https://clickitornot.com/unlock-bootloader-wiko-devices/ the commands would be
fastboot devices
adb reboot bootloader
fastboot oem unlock
Nothing, it gets stuck
i also tried fastboot flashing unlock_critical but same result, a flashing _
So you are using Windows; what was the source of your platform-tools (that is the suite containing adb + fastboot) and what version are you using?
It looks like you are in a adb shell, not fastboot.
As i have understood, Windows commands must start by
.\fastboot
.
You plan to try G.S.I. on this wiko ?
Im using adb 1.4.3.
Here: [OFFICIAL][TOOL][WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.3 | XDA Forums
I have the same result, using sdk plataform tools
Did you learn the way round the bootloader? Can you get a response from
adb devices
fastboot devices
when in the appropriate booting mode.
You say this?
Thank you 
I really don’t know the device and have no explanation, I am sorry.
Don’t worry I think I’ll do a factory reset and try again, if after factory reset the error continues I think I’ll change my device
Anyway, thanks for trying to help me.
if this can help, when i do fastboot reboot, my device dont reboot i need to reboot it manually pressing the power button
hi,
it could be a cable issue ?
it can, but i use the original cable
Have you tried having a Windows Device manager open while you try these commands. You will know that you are looking for a 
beside any device with missing drivers. It can happen that you installed drivers, but they don’t fully work for fastboot !
Even original cables can be inadequate; always worth trying another !
This?
1:
normal (without fastboot mode)
2:
my device normal (without fastboot mode)
(Final)3:
with the fastboot mode
