(06-11-2018, 01:35 AM)Jimslaw But how can one prevent it from backing up user files some user files are quite large
to achieve this,
you must use the method at https://www.hovatek.com/forum/thread-22701.html to get full length address
scroll to the end of the guide that says "Loaded PGPT file seems empty, what do i do?" -- the title is not important
in scatter tab, use the finish address of SYSTEM in place of the full length address [userdata and cache are usually below system partition, so just read upto system]

(07-11-2018, 05:56 PM)najim05 please i was able to do all those step but i encounter error while doing the full rom dump(error is attached in the image below)...but the readbabad ck did create a file with 4gb+ size and i try importing it to wwr tool it was loaded...can i extract the boot.img in the file to continue my rooting process?..
Retry the process and make sure you backed up the full firmware, things might go south and you will need the firmware to revive the phone.

You can extract boot.img from a 4gb dump but like @innagee mentioned it's best you dump full firmware or at least read back UpTo system (skipping userdata and cache) just in case the phone gets bricked

answer is still yes, but still ensure you have a properly backup before doing so
if you are unsure how to go about skipping userdata and cache when dumping using wwr method, then create a new thread so we'll focus on it
