wiping before upgrading rom

Is it 100% neccessary to wipe before updating a rom if its the same rom just a different version? Like I have cyans 3.6.8.1 and want to go to cyans 4.0.1
I'm just looking for some clarification on this matter. I know when you switch roms you want to but I haven't really seen anything concrete on upgrading roms. Any help would be appreciated

No, no, no.... you need to wipe when you use a bathroom, not when you flash software
People will hate me for this but... here it goes
We wipe to avoid problems with the new rom. We DO NOT know if we will have problems, good chance that we will NOT. I never wipe untill something goes wrong, and I was just fine for last 14-15 flashes.
Here's another way to think about it.... do OTA updates wipe your phone? Didn't think so.
Flash away. If you have problems then, and only then, nand back to your previous configuration, wipe, reflash. Don't wipe after flash... Cyan's roms don't like that AFAIK.
Good luck.

I heard somewhere that it's best to wipe when going from HTC rom to Google rom and vice versa. I know that for cyan's roms that if you rarely have to wipe (I had to wipe when trying out 3.9.11.*), but for the most part you won't have to (went from 3.4.6 to each update until 4.0.1 without wipe)

At this point..the only HTC roms we have are Hero and that's a whole another story. Not only you have to wipe but also reformat your sd. Big mess... not worth it IMHO. Your mileage may vary.
Thanks for ppointing this out though...

Personally, I wipe, then repair ext filesystems before I flash a new ROM. The only time I don't is when I'm updating a ROM that I have, cm x.x.x to cm x.x.x, in hich case I'll just repair ext's then flash. But, when in doubt...

Original question(s) seem to be solved.

Easiest Way to Flash Back to CyanoGen Mod Stable Version (1.4.1?)

I flashed to the CyanogenMOD 4.0.4 ROM then flashed in Ted's Hero theme for that rom and then all hell broke loss. My phone is suddenly unstable. To get back to the original 4.0.4 rom do i just wipe and then load it on again?
Also, any reason why a theme should make the phone unstable? It thought that all the theme really did was to replace some of the system images.
Thanks

Well I'm not really sure why in the world you would be using a CM ROM with version 1.anything... The most recent ROM is version 4.0.4. Now if you flashed his recovery image version 1.4 that is not a ROM and a theme will mess with a ROM it was not built for. If you really are using his ROM version 1.4.1 then Ted's hero theme is built for version 4.0.4 so yes you will run into lots of issues.
Yes, just wipe and reflash.
Also questions belong in Q&A.

Title should say 4.0.4? build not 1.4.1. sorry about that.

Did you wipe before you flashed CM 4.0.4 and the theme? You shouldnt have to but it might help resolve any issues. You also might want to reformat your ext partition.

try the wipe first, make sure you have the update.zip on the root of your sd card, then use the good old power off then hold home and power button and flash the update

I wiped before the 4.0.4 ROM install yes. obviously not between the 4.0.4 and the theme.
All i'm really wondering is to get back to 4.0.4 can i just wipe and reload? Wipe essentally clears the phone of anything that was on it correct?

wiped and reloaded 4.0.4 build, worked like a charm...thanks guys for help. quick side question...just need a short answer...is installing the stable hero rom that is floating around as easy as the cyanogenMod? or is it much more complicated?

You need to have the newest radio and Haykuro's Special SPL installed to run any Hero ROM. once that is on it is just as easy to flash a hero ROM. If yo install the new SPL make sure to follow the instructions exactly to avoid bricking your phone.

How do I install a kernel and update my ROM?

I have some problems here. I'm kind of a dummie here, so I think my questions aren't very tricky to answer
Android 4.1.1
First of all, I have CM10 NIGHTLY [05-09-2012] and I want to ask is there a newer version of that ROM? I'm pretty sure there is but how to I update it?
And the second question is how do I install this kernel? http://forum.xda-developers.com/showthread.php?t=1112908
I appreciate your help.

Hello!
Download the new kernel and put it on your SD card. After that open the recovery, wipe cache + dalvik cache, install the kernel and fix permissions. Reboot. That's all.

And my current ROM will remain the same, nothing will change? And the part with "fix permissions", what's that? :\

Oh, I've got it all, thank you, problem is solved!

You are fine to flash a new build over an old one without wiping data. Just wipe cache and dalvik cache, flash the new build, reboot and your good to go. The exception is if you are moving to a new version of android (CM9 to CM10) or if you are moving to a different ROM (CM10 to AOKP). In those instances you would want to wipe data as well.

Thanks, I do appreciate it. that's what I was thinking but you always want to be sure when doing this kind of stuff on your device.

question about installing a nightly update.

Hi i flashed a month ago aicp to my xperia sp and now i want to install a nightly of the same rom.Do i have to do full wipe or just flash the rom?I am using cyanogen recovery.I am asking this because in my previous rom i installed a nightly update without wiping and i ended up bricking the phone.

I read everywhere that the safest way is to do a full wipe, and since you have nothing to lose it won't hurt, so i think you should.

yes it is practically the correct way to update a nightly.
However do bear in mind that the nature of nightly is that it might have problems after different builds, therefore having a previous build zip handy would really help you. Also backups!
In case of a problem, clean flashing sometimes aren't really your go-to method to correct stuff. Always assume it as a last resort.. In case you faced any problem do kindly share here.

so i sould install the nighlty without wiping?

1. So you saying that a new update might/could be worst than the previous, correct ?
2. Do we need a full wipe of everything like first time (data, system, dalvid cache, etc) before install an update of the same rom (nightly 20151214) ?
3. Should i install it via recovery or ota ?

Yes, nightly is a daily release where changes are huge in the back end.. Sometimes a simple change can make a build unbootable. Sometimes it introduces new bugs. Sometimes it is better and fixes everything. It is of course a good thing to update to the latest if possible, it is just that it is also vital to know what we're going to face when we flash a new update. So that we can make backups beforehand in case something really bad happens.
If you are installing an update to the same ROM there is no need to wipe anything. Wiping is optional.
↑ Note, if you are reverting to a previous build, you will need to wipe everything as there will be conflicts for the system data. This is why frequent/periodic app backups useful.
You can do either both of them without any problem

Thank you very much.
It's the first time i flashed a custom rom (the AICP 10 successfully :cyclops: ) and i got overwhelmed with all these endless customization options .
