how to in tecno spark 8c get boot.img???

[Protey]

@TomKing062 thanks for helping me unlock the bootloader on tecno spark 8c! tecno_spark_8c.zip
Can you help me get boot.img from the stock firmware, since I don’t understand how to do this?

The phone has the latest firmware version "KG5n-F062RU-11.0-RU-V91-20231011", it is not available on the Internet.
Maybe somehow using adb shell or fastboot you can get boot.img?

spd_dump exec_addr 0x65015f48 fdl fdl1-dl.bin 0x65000800 fdl fdl2-dl.bin 0x9efffe00 exec read_part boot_a 0 64m bootbak.img reset

This command line be entered into adb shell or fastboot?
Can you write the actions in more detail?

all spd_dump commands are for SPRD U2S DIAG
open cmd and execute in the unlock tool directory

I apologize in advance for bothering you, and thank you for helping!
To avoid opening a new topic, I'll ask here.
I realized that the above command must be executed in the tecno_spark_8c folder with files from the archive tecno_spark_8c.zip.
I was able to get the bootbak.img file, thank you @TomKing062 for that!

I have another question, so that you are no longer distracted from important matters, is it possible to make a backup of the full firmware in the same folder tecno_spark_8c, if so, could you write what the command should be for this?

after root
adb shell su -c cat /dev/block/mmcblk0p1>p1
or see /dev/block/by-name/
