I have a swift phone with it is original OS "12.1.1-YOG7DAS2FI" and the phone already got two updates and downloaded them but I have never install any of them. the last one downloaded today is "13.0-ZNH0EAS2NH"

I saw many people are complaining about the new OS and others saying it is very good. so I am confused whether to upgrade or not. So I am thinking of upgrading, But I need to make sure I have everything backed up in case i didn't like the new OS. I need detailed steps how to completely backup current OS and how to restore it in case anything happened.

also If anyone can help and summary all cons and pros of the upgrade, it would be very helpful.

Thanks

if you have the cm-12.1-YOG7DAS2FI-crackling-signed-fastboot-07863145a7.zip file you can always 100% downgrade to that original OS (aka stock firmware) using fastboot for all parrtitions. Same way you can 100% upgrade to cm-13.0-ZNH0EAS2NH-crackling-signed-fastboot-2306277a34.zip stock firmware.

However going 12.1 13.0 back and forward will result in factory reset. Or you can factory reset first yourself and even backup / format external SD as well.

Here is howto flash any original OS

Code: 
fastboot flash splash splash.img
fastboot flash modem NON-HLOS.bin
fastboot flash aboot emmc_appsboot.mbn
fastboot flash hyp hyp.mbn
fastboot flash rpm rpm.mbn
fastboot flash sbl1 sbl1.mbn
fastboot flash tz tz.mbn

fastboot flash boot boot.img
fastboot flash cache cache.img 
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot flash system system.img
I have no complaints at all about 13.0 cleanly flashed that way. Not a single 'con'.
