Please, can I ask if that is correct? Do I have really to unlock the bootloader before to flash the ROM?
If I have to unlock the bootloader, can you post a link with a valid guide, please?
In the advanced options of my device there is a button who says: ¨allow the OEM unlocking¨. Do I have perhaps to activate this option?
I think that this is the last information I need before to flash
I thank you in advance and I wish you a nice evening.
Well, sincerely i don't know if bootloader unlocking is required for successful flashing, because I unlocked my device the fist day I bought it. So, when I decided to flash another ROM, my bootloader was already unlocked. But I think it's not obligatory.
Anyway, OEM unlocking is not complicated, so you can do it to be sure.
The OEM unlocking will erase your user data!
Firstly, allow USB debugging and OEM unlocking in the advanced options on your device.
Then, you have to install all the drivers
. Please read with attention this
(You can also read this
Now unpack adb.rar
to the root of drive C.
Connect your device to PC with the USB cable and confirm USB debugging.
Launch the windows command line (cmd) as administrator
and type the following commands:
1) Go to the folder with adb:
2) Check if adb recognizes your device:
If it recognize your device you will see your serial number. For example:
List of devices attached
If the list of attached devices is empty, it means the drivers are installed incorrectly.
3) Reboot your device to the bootloader mode:
adb reboot bootloader
Now you will see on your phone the black screen with "FASTBOOT mode" at the bottom.
4) Check if fastboot recognizes your device:
If it recognize your device you will see your serial number.
5) Unlock the bootloader:
fastboot oem unlock
Confirm the unlocking on your device using the volume up key.
6) Reboot your phone to the normal mode:
P.S. Sorry for my english.
