  2. You need to look for the ROM_FULL that we Read Back awhile ago that has a file size of more than 2GB and click OPEN.
  3. And now you will see on the Status window that it has created a folder where you can find the converted files and you will also see the file that it is converting.
  4. at the middle of the process the CWMR will prompt you if you want to create one which is you need to choose YES so it will create the RUA1 version of the CWMR.
  5. Just wait for it to finish and to locate the file all you need to do is go to the MTK Droid Root and Tools folder and click the Backup folder and you will see the folder that it has created and inside that you will all the files it has converted.
  6. after it finish the task you will now see the FULL ROM DUMP of you smartphone that the MTK Droid Root and Tools has Converted. and you will I put an arrow on the filename of the folder to you will know where it is located.
  7. you will see now the task is completed and the FULL ROM DUMP is completed.
  8. On the MT6753 it will create a Recovery and Boot image file that is patched and CWMR version but also it creates the unmodified version now if you want to use the unmodified version you will see it is renamed as factory_NONmodified_recovery.img Now this is the stock recovery if you want to use it simple rename the current recovery.img to other name and rename the factory_NONmodified_recovery.img to recovery.img or simply click the recovery on the SPFT tool as what you see on the image and locate the factory_NONmodified_recovery.img it will just work as the same. and same process apply with the Boot.img.

      1. so you’re saying that THIS MT6753 devices are not supported by the MTK DROID TOOLS to create a scatter file??
        as i can see the scatter is different from the 62380000 address you’ve posted,, so maybe im thinking,, it has a different address.. that’s why it treated my rom_full as null and error as it saves a wrong file location,,,
        i mean,, when i look for the 00062380000 scatter size in BLOCK DEVICES info,, it doesn’t exists..
        OR MAYBE I’m taking it the wrong way.. hehehehehe.. can you please guide me here??? thanks

        BTW.. ive watched and even downloaded the video posted,, where it says note the scatter hex,, up to the second to the last if i wanted to back up the whole rom,,
