Do i need to wipe first before installing a new ROM?, I have Virtuous Unity 1.31.3 and wants to install the new version 2.35 , install via zip? or upgrade? thanks.
Pretty sure you can run the update over the previous version
They are different bases I would wipe . 1.31 is 2.3.3 and 2.3.5 is 2.3.4 I would wipe to avoid issues

As a general rule, you can flash updates of the same rom without wiping data, although you might still want to wipe the dalvik vm and system caches. If you get lots of force closes, you might have to try wiping data though.
The Dev will typically tell you whether you'll need to do a full wipe in that ROM's development thread.

Search xda and research about android and common root knowledge.
It's always your choice. I normally wipe.

Always a good idea to wipe data and cache every time.

I'm currently running cm7 rc3. Do I need to wipe cache and data if I'm upgrading to cm7 rc4?

I did a flash over, didn't wipe anything. No problems as of yet.

Its usually a good idea to at least wipe cache and dalvik. Shouldn't have to worry about data unless you are having problems.

Wipe cache and advanced>dalvik. Then apply the CM.zip, then GApps,zip if you use those, and then any custom kernel that you use.
Doing a backup beforehand is always recommended

Same thing here, no problems yet.
Rule of thumb is to just wipe the cache/dalvik if your updating to the same ROM, just a new update. It's really only when your cross-flashing a different ROM where you need to do a wipe data/factory reset.
Ok this might be a stupid question but I didn't find an answer when searching. I am running the Ginger Villain 1.8 rom version on my G2 phone but no matter how many rom updates I install my "Mod Version" always says GingerVillain1.4. Shouldn't it change with each update I install? Also my Android version never changes from 2.3.1 but i see other threads with pics showing 2.3.2 and 2.3.3.
Maybe try and do a fresh flash. Wipe and all that jazz?

Thanks for the reply. I tried multiple flashes that but still never changes from gingervillain 1.4. I always wipe data, cache partition and dalvik before every new rom install. 1.4 was the 1st rom i ever flashed so i don't know if that has something to do with it or what. I'm going to flash Xboarder56 v1.9 tonight and see how that goes but i'd still like to know why my Team Villain roms mod version stays the same
New to XDA, first post ever. Has anyone tried the new Kingdom Sensless 3d release and if so can you tell me if youtube is working as well as 720p video recording? Tried to post this in the developer section under the proper thread but it wouldnt let me since im new. Would love to know overall thoughts on this release as well. Thank you!
Sent from my Incredible using XDA Premium App
I believe YouTube works with a workaround (wifi has to be on but not necessarily connected), but 720p isn't functional yet.
is my daily driver everything is working fine there is a lag on the 720 but the devs have explained that is do to the fact that they dont have the codes or something to build new kernels.. youtube works just fine... if you haven't try it yet just flash it... you wont regret it..
Sounds good. Thank you. And just to be sure, i boot into recovery, do a factory restore, wipe cache, then install the zip from sd card. Is that the proper method to install this or will that screw up my phone? Thanks again!

Also, i currently have a different sense 3.0 rom installed. Do i have to flash back to the stock rom before i attempt to install a new one or can i flash a new rom over the one i currently have installed? Thanks again peeps!
Sent from my Incredible using XDA Premium App
No you don't go back to stock before flashing, yes go to recovery do factory reset, then go to mounts and storage and wipe boot, system, data, cache go back under advanced & wipe dalvik. Now you can install your ROM
Sent from my ADR6300 using XDA Premium App
Thanks very much. Interestingly, when i go into recovery it brings me to a clockwork recovery screen where i cant do some of the things u mentioned. I only have the options to do a factory reset and wipe cash. Is that enough? Does it matter what order u do them in? I also noticed that in titanium backup there is an option to delete the dalvic from there. Is that ok to do?

Go into advance in cwm to wipe delvic

Also, you can format system in the mounts and storage menu. The rom's install script should include this, but never hurts to be safe.
I flashed Sandvold's ICS 0.8.1 yesterday, but after reading a few threads today I saw that it's better to do the custom install instead of the typical one. I did a nandroid and decided to simply flash the rom again without clearing anything.
It seems fine so far, but I'm wondering if this can lead to any problems?
Also, do I need to reinstall a2sd after re-flashing?
I think that if you downgrade from ics to gb than you need to make a full wipe but if you upgrade than I think it's ok

If you are with the exact same rom then a wipe shouldn't be needed and a2sd should stay if you don't wipe.
Try it and if it doesn't work do a full wipe I've never seen anyone say you'll break your phone if you don't wipe. Someone on Sandvold's thread recommended app extractor from play store as an easy way to restore after a full wipe. Didn't work for me but I only tried it once so you could check that out. It just restores everything from your nandroid

If u are flashing the same rom (newer version) u still have to wipe dalvik. Its better anyway just to do a backup then full wipe and flash the rom then restore

Always wipe Dalvik, sometimes, the rom setup menu does it automaticly.
Hi all,
First post on xda here. I was trying to update my frosty jelly bean v6 to v7 via OTA update, installed the package and it restarted itself in CWM mode but it said something alone the lines of "failed update... update file not found." I downloaded the v7 package from the developer's link and was thinking about just installing it from zip on sd card.
Why can't it update? If I install v7 from the zip and wipe cache will that work too or no?

Install from CWM yourself, as you suggested.
Do I have to perform a full data wipe for that then? Or would just cache and dalvik cache be ok.
Not really sure why OTA update didn't work in CWM in the first place, if anyone can offer answers that'd be helpful. Thanks!

This what you do after you put the zip in the scard...make sure your in recovery..
Wipe data/factory reset
Wipe cache & dalvik
Install Rom
Wipe cache and dalvik (again)
Fix Permissions
Reboot & let it sit for 5-10 mins (Don't touch anything!)
Reboot & enjoy!
*Please perform a full wipe for v7!
Hope this helps.
Thanks. Yeah I saw that on the dev thread... I followed those steps when i first flashed the frosty JB. But my question is do i really have to do a data wipe even for every version update? That seems to be a lot of hassle...
Sent from my SGH-T999 using xda app-developers app
Wipe Dalvik and dirty flash it. 4.1.1 > 4.1.2 = no clean flash necessary. I guess it's the devs' fault for spreading all of this clean flashing nonsense that's been more contagious than the bubonic plague. Like the IMEI loss rumors. It's only necesary if: going from ICS to JB, or vice versa. Or if you're having some major issue that no one else is having. Which is rare.
Thanks for the suggestion. I tried to dirty flash it but it said the signature verification failed?
Just to note the only tweak I made to my sd card previous to trying to update was deleting the original frosty JB v6 zip. That shouldn't matter right?

What is the version of your CWM? i think its need to be updated.
3.0.7
Sent from my SGH-T999 using xda app-developers app
Yup, update it, the latest version is 6.xxx. i encountered the same error when i tried to install cm10 with an outdated cwm.
For a noob, you can easily update cwm by downloading and installing ROM MANAGER using your phone from PLAYSTORE.
launch the rom manager app then you can see an option there to update cwm
Id like to make a quick point on the dirty vs clean flashing.
Usually, it is correct that dirty flashing is ok except when jumping between android versions. (Even then, when going forward in version, its still often ok to dirty flash).
However, in the cases we see here this is not necessarily true. I am of course referring to our jb leaks and roms based on them.
Dirty flashing these after an update can cause problems. Many people, myself and the devs themselves included, have seen where a number of bugs would be nonexistent if you just did a clean flash. These are experimental builds based on leaked firmware. I'm certain the devs you guys are referring to recommend a clean flash for two reasons. First, it simply makes their rom operate much better. Second, and most important from a dev standpoint, if you dirty flashed, and are experiencing bugs, there is nothing the dev can really do for you. In fact, unless you clean flashed the rom, you shouldn't even report on bugs unless you find a fix for it.
Another thing to consider is a couple if these roms are based not just on a leak, but on multiple leaks often from more than one carriers device! Due to this, if you dirty flash you are much more likely to have bugs show up. It really depends on what has been changed, updated and rebased, and no one can predict how uts going to act.
No one says you cannot dirty flash these roms. Many have done so with few to no issues. But, if you do, and you run into problems please do not blame the dev or expect him to fix the problem unless it is being reported by the majority of users.
Not trying to argue or say anyone is right or wrong. I'm just trying to clear up the reason for the dev suggestion to clean flash.
Hope it helps!
