Question about boot.Img - OnePlus 5 Questions & Answers

What exactly is a boot.img file and when should I backup/install it?
Does it have the stock recovery? It's the same as we do on windows with adb and fastboot flash recovery img command or did I confuse them?
Should I take backup of boot.img when I install a custom rom or kernel?
Please help me guys. :good:

The boot.img is the kernel.

What does a kernel contains and how it differs from a custom rom?
Can I flash a kernel without backup?

Need help new boot loader

Actually I am on modified twrp
Now if I flash CyanogenMod 13 with this modified twrp
Does it boot on u bootloader cause a problem
I just wanna get rid of oxyzen 3.0 and wanna flash CyanogenMod 13
No, you will have to flash one of many revert zip-files back to OOS 2.2.1 to get the old bootloader. Then you can revert TWRP to the one for that bootloader and then format data and reflash CM13.

If you mean if you can use two kernels simultaneously the answer is no.
Dirty flash your ROM and flash the other kernel.
It's possible to flash another kernel over the actual one but it's not recommended.

Dirty flash your current ROM, after that you can flash your new kernel via fastboot (kernel has to be in your ADB & Fastboot folder)
fastboot flash boot nameofkernel.img
Or flash it via TWRP (kernel has to be on your internal or external SD)
Install - chose .img instead of .zip - locate your kernel - swipe - chose boot.
Reboot.
