Use Doomlord V4 to root your phone
Connect i USB and choose USB Debugging
open the CMD app and press enter the phone will restart and you got root
then download the recovery files- IE ClockWorkMod
Connect phone - And hit the right CMD

Unlock your BOOTLOADER !
IMO you should unlock your bootloader by testpoint metod, which is quite easy and you don't loose your warranty for ever (you can recover bootloader).
Easiest metod to gain CWM and root is to install NightElf kernel by fastboot and .62 firmware by flashtool.

i also need to unlock the bootloader to flash a custom recovery and rom but can'y do it,
i've tried every possible ways but still isn't working.
Did you guys try the nexus way?
Enable usb debugging
Connect phone to computer with adb
On the computer type "adb reboot bootloader", wait for reboot
On computer type "fastboot oem unlock"
Check phone for confirmation
Reboot if necessary
This may do a factory reset, so back up your user data before doing this.

How to unlock bootloader on Mediatek device

Secure booting unsuccsessful after brick

hi, I have a p760 that I use as backup phone.
Today I try to power on it and I had security error, so I don't remember what I did with this phone, and I follow THIS guide.
The problem is that
adb oem-unlock
Click to expand...
Click to collapse
doesn't exist. 'cause
HTML:
adb reboot oem-unlock
is the only one that works.
If I give the command adb reboot oem-unlock the phone gives me a black screen with Secure booting unsuccessful.
I try to go in s/w update mode but kzd crash.
So I think that the only way is to unlock the bl, insta cwm and install a custom rom. but how?
can someone help me?
some people with the same problem?

Yes, but on reboot it automatically disables it. It's not permanent

Try this method :
- Switch on the OEM unlocking option in Dev Opt and plug in USB to PC and direct booting into bootloader using ADB cmd
adb reboot-bootloader
- Navigate to PC device manager and look for new device detection and update driver. On Update Drivers popup, navigate to Properties TAB and choose 'Hardware Ids' from scroll menu, rightclick and copy the first id that shown and google for the drivers.
Sometime, from my experiences, PC might say the driver installed for our phone is correct, but it isn't. Thats why when we enter fastboot cmd eg :
fastboot oem unlock
nothing will happen, bcos the driver isnt correctly designed for it.
Well, good luck trying...
