Updating your custom rom?

hey
I'd like to know whether it is possible to update your custom rom: for example I have Nextgen 2.1 and want to update to 2.2 but when I flash it everything is deleted. Is there an option to only update it and not flashing it?

[Q] Stock recovery question for OTA

I found This topicon how to get back to stock recovery. My question is wouldn't you have to be on stock rom and the stock hboot for the OTA to work? or the HTCinstaller dosen't car just as long as the stock recovery is still intact?
I dont see the point, but thats just me.
New update comes out =new custom rom (stock or not stock) on xda
just backup important data before flash. some roms dont require a wipe if u r coming from the same rom 1 version under.
check rom threads. IMO no need for OTA.

[Q] Custom Rom problems

Has anyone else had problems trying to install roms like cyanogenmod after the Jellybean update? I used to be able to install CM9 nightlys then eventually stable releases and back to stock with no problems, so i am not a noob to flashing roms. Now after I updated to stock 4.1 I cant install CM10 or any other custom roms. I have tried installing through CWM and TWRP but cant get past the ASUS screen after flashing the usual way. I heard there was a change in partition sizes when the update applied. Is there a way to install custom roms again or am i doing it wrong now?

[Q] Installing rom without wiping all data

Hello everybody,
Recently I was browsing some threads about the new note 10.1 (2012) update and I found a rom based on the latest firmware 4.4.2 kit kat. I really liked the fact that it had the note 10.1 (2014) features built-in.

There's only one downside to this rom (like all custom roms ), it needs a full wipe. But I'm a bit lazy and I don't want to backup all my apps and restore all data. I know it's based on a firmware update and normal updates don't need a full wipe. So is it possible to flash this rom without losing all my apps and without wiping everything?
I read something about only clearing Dalvik and cache, but I want to be sure. I'm on clockwork recovery and have the stock Gt-n8010 rom.
Thanks in advanced

Questions about kernel, custom rom and flashing/Ota updating.

I have an OnePlus5 with latest Oxygen Os android 7.1.1, rooted with magisk and with TWRP recovery. I flashed yesterday a custom kernel (blu spark), cause i wanted better battery stats. But i dont see any changes. Nor more advanced options, neither visual changes. What does exactly a kernel change to the phone? How does it differ from a custom rom? Do i need extra programs or programming in order to make full use of the kernel?
Now that i have the custom kernel, what actions should i take if :
1) I want install a custom rom
2) I want install stock rom
3) I want install another or stock kernel
When should i take full backup and why? (Nandroid via TWRP or backup with TITANIUM BACKUP??) What about OTA updates? How can i update to newest rom in each case? Each time a new rom update occurs should i take full backup, flash the rom and install them all from the start??
Someone help me please?
