(11-06-2021, 11:15 AM)X3non you'd need to have a preloader for any kf8 and include it within sp flash tool before attempting readback ; refer to https://www.hovatek.com/forum/thread-439.html
you can download the firmware @ https://www.androidfilehost.com/?fid=149...7586347824 ; you should find preloader within

Hi, I can't thank you enough for dumping the preloader for me.
I was able to create a full rom dump and it works!

My main intention for all of this hassle was just to get magisk working.
So I tried flashing the magisk patched boot img from both fastboot and spflash tool but it ends up in a bootloop.
That means, it keeps rebooting right after the phone exits OEM logo screen.
I was able to boot again by flashing the stock boot.img

You know that this phone got android-11, do I still need to disable dm-verity if it's enabled?
I'm asking because you didnt mention android-11 here: https://www.hovatek.com/forum/thread-21427.html
But you mentioned about a9 and a10: "For android 9 and 10 devices, ensure to disable dm_verity by flashing an empty vbmeta before flashing magisk patched boot."

Any ideas?
Thanks!

*Update: I just tried the method-3 of https://www.hovatek.com/forum/thread-32719.html tutorial but it says "FAILED (remote: 'No such file or directory" in fastboot when trying to flash vbmeta partition with both of the provided commands. (Please see attached screenshot if required)

*Update 2: I could flash vbmeta partition from bootloader-fastboot and not fastbootd.
Basically I was making a mistake of getting into fastboot by: "adb reboot fastboot" and not "adb reboot bootloader".
So I was finally able to accomplish what I have wanted! I will soon share my full-rom and rooting instructions in a github repo of mine and let you know!

Thank you!

thanks for pointing this out, the guide was written a long ago, we've updated it now

Hi again!
I just made a quick guide referring to many informative hovatek tutorials in a well-tailored way for "Tecno Spark 7 Pro" specifically.
This can be found at https://github.com/supremegamers/mt6769
This repository contains most important files for now, I will upload the full rom later since I'm running low on mobile data currently.
Thanks and take care dude.
