is there a way to update ROM instead of doing fresh install?
I have unofficial XenonHD for S7 edge
https://forum.xda-developers.com/s7-edge/development/rom-xenonhd-t3544403
And I have Feb 25 ROM and dev recently released March 5th ROM, which fixes number of things
I need help with updating ROM but it doesn't support OTA because it's unofficial version.
Does anyone know how to update this ROM without resetting anything or staring fresh?
for updating the developer has put in this comment.
. Make a full wipe (system, data, cache, dalvik-cache). If you're updating ROM or have other 7.1.1 already you may not need to wipe data (just wipe system, cache, dalvik-cache)
try doing it without wiping the data as per the developer instructions but make sure you have a back up available in case of issues.

Disclaimer: I'm used to my old Evo 4G and use a triple wipe script built into my recovery (smelkus) whenever I flash a rom. It pretty much wipes everything.
For the Nexus 7, what needs to be wiped to flash a rom? I did a factory reset, wiped data, wiped cache, wiped system, wiped dalvik-cache, and then flashed a new rom, but I wasn't sure if all that was necessary. I'm using the latest TWRP recovery.
If I'm moving from one rom based on a jelly bean version to another based on the same version, am I ok?
Can I assume upgrading to a new version of the same rom that I don't have to wipe? (I know this one is rom specific, but in general.)
Can I leave data and will that retain my apps? Otherwise, I use Titanium Backup religiously on my Evo and now on my Nexus 7.
I searched within some of the rom instructions as well as the rooting guides, but didn't see anything specific as to what to wipe. Some threads seem to say just factory reset and maybe dalvik-cache.
Instructions with what to wipe usually come in the original post of each ROM. Usually the same ROM with different version only requires a cache wipe while moving between different ROM's requires a full wipe/reset + dalvik.
Worse comes to worse you try something and it doesn't boot and you get back into recovery and fix it.
I didn't want to bother the team by sending them through the "important question form" webpage.
Neither can I ask them on the development thread on XDA.
I am currently on the slimbean 4.2.2 build 3. Going to build4 the team recommend a full wipe, but then the update of build-5 did not specify such step. I wonder if that means from build-3 to build-5 an easy wipe (wipe cache and dalvik only and flash the latest build-5 rom) is sufficient to make a successful update.

To be honest this is never advised. Too many artifacts from the prior rom can cause issues. IT is always best to do a full wipe before flashing another rom. Be it update or not.

Most of the time it doesn't matter. An update that specifies a wipe should have a wipe during the process. A build after a build that specifies a wipe should have a wipe during the install if a wipe hasn't yet been applied.
So yes, OP you should wipe from 3-5 as 5 is built off of 4 which requires a wipe.

Hi,
I've recently done a succesful flash of Blisspop after a full wipe.
Now I want to update, but I don't want to do a full wipe. Simply installing the zip on-top gives a permanent booting screen. Can you update without starting from scratch?
Did you wipe cache & dalvik after flashing updated zip?
I did not. Is that the only required extra step? And will I lose data if I do so?

No, you only lose data when you wipe the data partition
In recovery, you'll see different named partitions, cache, dalvik cache, system, data, etc etc
If you wipe System, you wipe the ROM
If you wipe Data, you wipe your user data
Caches are just temp partitions, safe to wipe any time, only side effect is a longer first boot as Android needs to re-cache everything
But yes, you do need to wipe the caches when updating to a newer version of the same ROM/Droid version, and no you won't lose your data
Here's how I do it:
Wipe System
Wipe Caches
Flash new ROM
Flash new Gapps
Flash SuperSU if needed
Wipe Caches again
Reboot
Result = New ROM with no loss of data
That's a clean flash, a dirty flash is how you did it without wiping System
If you are moving to a newer version of android, or a different ROM, wiping data becomes more necessary, especially if the move is to an older version of droid
Thanks. I'll try it out.
Hello there, i installed a rom on my galaxy s4.. But kushan put a newer update of that rom.. what should i do? backup apps and just install the new rom above the old one?
That is called a dirty flash, or dirty installation.
You can do that. But there is a chance of problems.
A clean flash (wipe data, system, cache and dalvik cache) is generally recommended to avoid problems.
Do you we need to wipe vendor before installing custom rom?
I always wipe system,dalvik,cache and data.
You should not wipe data folder. You will lose your app data. Wipe system, cache, dalvik and vendor.
So yes, you need to wipe vendor before instaling.
Also, do you have to start a new thread for this question? It will just spam people.

Wiping vender might give into bootloops some times. And wiping data is always a good practice when ur switching ROMs.
So I'd say , take back up , wipe syst, caches , dalvik , data !
I know the topic is old, but it might help somebody in the future.
I have a Xiaomi Mi6, and in Miui 10, I got microphone bug, sometimes microphone worked, sometimes not, and also hang up sometimes out of nowhere.
I was pointed out that the reason may have been to just have given a wype system, dalvik, and date chache, but have not given a wype vendor.
So in doubt, because of bug, good give a wipe vendor.
i always suggest to wipe vendor, I've never faced any problem
What is reason ppl wipe vendor anyways?
Last time when I wiped vendor, it only start in download mode and forgot how to get out. It wasn't fun. And I never wipe vendor before flashing ROM, so I would say no don't wipe vendor.
