Recovery – CWM

!!!I recommend backing up the nvram with Mtkdroidtools before using Spflashtool to keep the imei, otherwise there would then insert the end of the process once the terminal with the new rom rebooted.!!!!
-Donwload and unpacking SP_Flash_Tool_v5.1348.00 -Rom and rom s660 China version
-Off the phone and remove the battery
-Run SP_Flash_Tool and selected MT6582_Android_scatter.txt on rom directory
-Download press release o download/firmware
-Connect phone without battery
-When the green circle appears the battery and turn on the phone.
-When I start properly, shut down again and go into recovery mode ( pressing "Power" then"Volume +" and select boot recovery.
Select "Wipe data / factory reset" and run
Select "Wipe cache partition" and run
select "Advanced" and then "Wipe Dalvik Cache" and run
Select "Back" and run
Select "reboot system now" Program
- And wait for it to restart, you can restart several times. It takes a while.
And if all goes well will be all set.
Adding this Mtkdroidtools for you can reinstall the IMEI and you can backup the IMEI.
