Khalyl22 said:

bro this guide is so long and boring and not safe
the best way to root this phone is through mtk client (github)
with that tool you can
1.backup the whole firmware in case of an error or a malfunction
2. unlock bootloader of any mediatek phone including oppo a5s
3. rooting this device without any risk
4. you can flash any partition if something happened within this tool without the use of SP Flash tool
the link: https://github.com/bkerler/mtkclient

NOTE THAT I WARNED PEOPLE BEFORE DOING THIS

@Anonymous V What are your comments about that ?

actually he is just saying about what can you do using the MTK client tool not "what to do about it " and i dont know if he really read your tutorial because this guy " @Khalyl22 "
sounds that he just wants to sounds smart and also boring? i dont know why he said that but its better to give a long and detailed tutorial to give people more info and understanding about what to do to avoid error and to give comfort to people while doing it and i dont fcking know why he said that its not safe although you give all the necessary steps to avoid error while doing it including the warning " Please Backup you Phone before Doing This " and also i think his not aware about the MTK client Gui version which you used in your tutorial i recommend the Gui version for the people who cant handle the terminal version because they are afraid in getting error i think he is pointing about the MTK client terminal version which i often used, also bro there is a reason why he said backup your whole firmware before doing it and actually his right about that when you backup your whole firmware in your phone you can backup all the data,apps,system preferences,imei and other things which you can restore if the phone fcked up where as the stock flashable rom is different its because its already set by default or factory default by the manufacturer which means its back to old state when you bought the phone well it depends though if you dont care about the data in your phone you can just reflash the stock flashable rom and if you care about the data in your phone you can backup your phones firmware and use that later to restore your phone.

@Anonymous V @Zezo 089 , any solution guys? only boot is ticked by the way.

turned out, preloader_oppo6765_18511.bin should be on the same location where scatter file is even though it's not tick. Anyway, Thank you @Zezo 089 for this post and for your contribution @Anonymous V . Despite encountering issues then trials and errors, finally I was able to root my device. Thanks again guys.
