Can you boot into the bootloader?

go to settings > about > software information > more : hit Build number 7 times till you get message (you are now developer)
go back to the settings screen, scroll down, you will found new option called (Developer options)
hit it, new message will appear , hit (OK)
now in the (upper right ) hit the (off) icon to change to (on)
find (USB debugging) and mark it
now adb will detect your phone
about the UNLOCK_CODE.bin, re-send your phone "token code" to the HTCDev.com to receive the UNLOCK_CODE.bin again and try again

trouble with bootloader unlock

Hello everyone, I'm trying to unlock my bootloader but I have hit a roadblock and cannot seem to find anything that helps.
The part where i am stuck at is that when i enter "fastboot.exe -i 0x0fce getvar version" all i get is "waiting for device" infinitely.
I know the phone is in fastboot mode because the blue light is on
It seems my pc isn't recognizing my phone when it's in fastboot mode. I can see my phone in windows device manager as "S1 boot fastboot" but when i try to update the drivers manually using the drivers provided by sony, i just get an update failed screen.
any help would be much appreciated, i'm sure it's something dumb that i did, but i just can't figure out what.

try using different usb cable/ different port.

Had same problem....some driver was missing

I've finally gotten flash tool to work, however now it gives me an error saying that my device cannot be officially unlocked,
EDIT: i'm pretty sure i've unlocked the bootloader now, as flashtool had me enter an unlock code and my device has had all of its data reset.
however my issues continue as now flashtool utterly refuses to pick up my device. I have re-installed all drivers, flashtool, etc but still nothing.

sometimes it may have conflicts when flashtool and other tools use their own instance of adb or fastboot. I think the best thing to do now is reinstalling regular drivers normally. don't forget to enable usb debugging...
this may be useful :
Code:
[I]ADB_PATH[/I]\adb kill-server
exit
create a text file, paste this code then save it as ADB - Kill.cmd

Unlock Bootloader P9

Hi guys, I need help.. I installed DC Unlocker and downloaded the drivers of Huawei.. The problems are:
- I don't have MODEMS and PORTS in Device Manager so, how can I install the drivers?
- If I go on DC, the Unlock button is grey (not clickable).. I put the device in manufacturing mode, debug USB activated and OEM also.. Already bought credits to unlock..
The website of Huawei don't work, says me Error.. How can I unlock the Bootloader?

I think you need to get the unlock code from Huawei...

try this, i got from emui website
Note: to re-lock the bootloader after unlocking it, restore the device’s software to the Huawei official version using a microSD card then switch the device to fastboot mode and enter “fastboot oem unlock ****************” in the computer’s command prompt, where * refers to the 16-digit unlock password. The device will then restart, and the bootloader lock status will change to “Bootloader Lock State: RELOCKED”.

Well I tried, I've not got a clue what I am doing, it's still unlocked so I will leave it as it is, I have a working phone don't want to mess around with it and end up totally ruining it

Try installing the update via dload

... (3 dot option) and then, download latest full build inside updater setings, thry that need to be around 2gb file

Ok so I managed to sort this out...... finally, just one thing else how can I change the lock screen picture, it gives me the option to do so but I select the picture but remains the same as it was, any ideas?

Device automatically change from Fastboot to charging

Hi, Im using the latest Global rom and I try to unlock my phone to day but the unlock tool keep appear the "Couldn't verify device unknown error (-1) at 50%"
Turned out that's because the devices refuse something from the unlock tool and if I try to do the command "fastboot devices" 2 times, my phone will appear small line text on the screen top like: "press any button to shutdown"
Every necessary driver installed
It's should be the day my phone able to unlock after 1 week
Glad if someone guide me to fix this problem

This actually happened to me and all I needed to do was reboot the computer so try that otherwise I don't know.
