Soo , you have no service and can't make calls ! follow this instructions and you will be talking on your phone in no time
Its very simple : ( i'll add the necessary links / software for this job )
1. you need SP_Flash_Tool_exe_v3.1316.0.150
2. you need the WORKING ROM ! modified by me
3. you need MtkDroidTools
( this version is allready modified to work with mt6572 )
The procedure :
we must first format the phone using SP_Flash_Tool_exe_v3.1316.0.150 . soo we open the program and select the scatter file.txt atached in the rom . hit format and then hit OK.
Now remove the battery and connect the usb cable to the phone. it will start formatting the phone. wait till is ready ( you will see a green circle )
At this point , the phone is ready to receive the new ROM
you have allready selected the scatter file early'r .
THIS STEP IS VERY IMPORTANT !!! uncheck the CACHE and USRDATA at the bottom.
Now hit Download button , you will get a warning message, just press YES
Now put the baterry back into the phone, and connect the usb cable. wait till the process end's and when you see the green circle you can disconect the phone, remove the battery, insert back the battery and power on the phone , and voila !! your phone have working network !!
Next step is to write the IMEI...
Use MtkDroidTools ( you must have debugging mode on in the phone ) connect the phone to the usb cable, wait till MtkDroidTools see your phone , and then hit the big imei button. There you must provide the imei number ( you can find it under the battery ) after that you hit write imei and then reset your phone and you are good to go
I presume that you allready have the usb drivers ( if not, i can also provide them )
