Do I need to wipe data after flashing an official firmware? - Galaxy S II Q&A, Help & Troubleshooting

I have heard mixed things on this subject, I haven't wiped my data after updating to KI3 and there are little to no issues (I have gotten about two force closes since it came out).
I also heard that if I root I lose my data, is that correct?

If you aren't facing any problem then don't but otherwise do a Full Wipe. Before doing than make Backup with Titanium.

So if I experience any issues, then root, back up and then wipe? I haven't rooted yet and the only use I will get from it is backing up. But that is useful thank you.

i don't think so just make a backup !!!!!!!!!!!!

I'm not quite sure what you mean.

IF you don't experience any problems don't wipe, you're alright already. Now, if you have problems, wipe your data, but then you'll have to reflash. You don't wipe after flashing, you must do it before flashing.

Oh I did not know that. I haven't encountered an issue yet, does it happen very often?

Well, when flashing from a very different firmware to another things might not work well, and the problem is you on't know what's causing the problem. At least I always do a full wipe since I backup all my apps with titanium backup pro so set my phone again takes me little time. Try your phone for a couple of days and just wipe if you need to, if not keep enjoying it as it is.

Thanks! Everyone has been very helpful.

[Q] Update to a new version of a ROM, should I wipe?

I am currently running KaosFroyo v30 and just recently downloaded v31. Should I wipe my phone before installing the latest version of this ROM?
*Note: it does call for a wipe when installing v17 it reads " **THIS IS A WIPE INSTALL** " does that apply to all ROMs post v17?
Edit: I know I should be asking Kaos himself, but I thought I would ask the community first.
If he doesn't say to wipe in between you don't have to... I personally always wipe the dalvik cache before and after I install a new update even if it's not required.
Well, I did what you advised and everything seems to be working out well. Of course I only just recently updated, so tomorrow and Friday will be test days. One thing i have noticed though us that MMS is till not working....
Like Hungry Man said, you don't HAVE to wipe unless the dev says so, but things always seem to be a lot cleaner when you do wipe.
I always recommend wiping.

I always wipe disk and Dalvik.
Only takes a second.
And with Titanium and what not, you don't even have to do anything.
They're making things too easy for us, lol.
You could flash with out wipe then if you have issues beyond known bugs, wipe and reflash.

If you dont have many programs or apps installed then do a wipe but for me it is a pain in the ass setting it all back up again. So, if it is just an update, then I dont wipe. Sometiimes it leaves scratchy ass, sometimes not
I have always wiped updating to a new ROM, mainly because I didn't know any better. The next update I might update after V31 I might just try a flash and see what happens because I'm impatient when reloading everything LOL.
If it is a new completely different ROM then yes I would wipe.
Installing a new ROM, updating or new, is like talking a shyt. You should probably wipe.

most importantly like mom alwayz said , wipe good
Wiping will get rid of all the clingy bits, which isn't always necessary, but I recommend it.

I ended up not wiping (no pun intended) no problems so far. I like some of the little tweaks, but I don't think the track ball lighting is not working

[Q] "Clean Cache" & "Full Wipe" with xRecovery prior to flashing new rom?

[Q] "Clean Cache" & "Full Wipe" with xRecovery prior to flashing new rom?
Is it true that the best way to keep your phone in optimal state, is to clean the cache and do a full wipe with xRecovery every time before you flash your X10 with any (new) rom?
A friend told me that if you don't clean cache and do a full wipe before you flash to a new rom, the cache content of the rom you're on cannot be removed after flashing to a new rom because the new rom has no re-collection of the contents of the cache from the previous rom you were on.
That's bs... Xrecovery cleans the cache and wipes for you, watch what it says while you're flashing and you will see.
I always recommend doing it anyway just in case, full wipe, then wiping cache partition and finally dalvik cache.
I don`t know and really don`t care
I simply just wipe/clean EVERYTHING i can before any installation.
Result?
Never had most problems users have. Ever. So i will continue

But if it is bs and xRecovery does it for you. Then why do you recommend doing it anyway? You got me slightly confused here.

All I'm saying is if you forget it's not a huge deal, and what he is saying isn't true...
I do it anyway just because when I had a htc hero devs used to recommend you did, so force of habit, yet I know for a fact that what he said isn't true. It could perhaps miss some data which is why you should still wipe, but that data would definitely not be stuck in limbo forever..

if not switching roms, does it make a difference to your system performance to occasionally wipe the dalvik cache and cache partition?

I did it on beta 4 and it actually made my performance wayyy worse.. so much so that I had to go back to an earlier backup I had made. MY linpack dropped from 35 to about 6 and the battery started getting super hot, and was dropping insanely fast.
I wouldnt recommend it during usage of a rom. What you can do is get a cache cleaning app and use that regularly! I use cache cleaner ng

I think this will help you get a "clean" install and saves you from other problems later?
Or is there Cons to always doing this?

[Q] Laggy i717 JB - Fix or ROM?

I tried CM a while back (WAY back, actually - pre-ICS) for the i717. It wasn't bad but after a while I went back to stock because for me it just 'felt' better. Hard to explain it other than that. In any case, I've been on full stock ever since and was happy with it.
Then Official JB comes out from the carrier and my phone is laggy as all hell and it's gotten to the point of royally pissing me off to the point that I'm considering my options.
My question is this: Do we know the cause of the lag? If so, is it fixable via custom kernel or something similar, or do I need to go to a whole separate ROM to get away from the problem (and are there any in particular that are recommended if that is the case)?

Have you done a factory data reset since the upgrade? That seems to clear up a lot of issues too.

I don't recall, but if I had to venture a guess I'd say probably not. I followed the above thread to the 'slow 4.1.2' and disabled everything I could on that list and did a restart, not sure which one did the trick but now it's nice and speedy.Hoping it stays this quick and isn't just a factor of not a lot built up in memory yet. I'll try a factory reset if it bogs down again.
there could also be some existing apps that continue to run in the background.
you might either go into app manager and force close them and clear their cache individually
OR
maybe reboot phone every day or two. clearing any cache build up. kind of a preventative maintinence thing.
if you ventured new ROM, may I suggest Padawawn.
every phone is a bit different, but I have had the best results ever
4.2.2 ROMs perform better IMO. Good luck

i prefer stock as well and was also experiencing lag until i found the right setup for myphone. started out by debloating. then flashed phasekernel_jb.3 and use setcpu or whatever tuner app you prefer and set governor = fantasy/scheduler = sio/min = 384/max = 1728. all phones are different so you may need to try different settings to find what works for yours. i have not had any lag since.
Here is what worked for me. I had the same issue as you and posted it a while back. This also greatly increased my battery life. I suggest that if you are rooted go ahead and wipe the device - in fact do it twice! You will have to reinstall of you your apps but it got rid of all the lag and almost doubled my battery life.

When you said "wipe", did you mean factory reset or TWRP wipe?
If TWRP, which one you wipe? I tried checking all selection and it wiped even the OS!

You wipe the caches. If you wipe system, it will delete the OS and the data wipe will wipe your data of course.

OK.
I am ready to do the factory reset twice. My Note is rooted and have SuperSU. If I factory reset, wouldn't it remove SuperSU also but NOT TWRP?
If yes, can I just install the SuperSU zip from TWRP? No need to re-root?

You will have full root. I always wipe both caches, system and data when flashing a new ROM, its actually the preferred way.

Wait, I already have stock AT&T JB and rooted. I just want to fix the lag and not installing a new ROM. Do I really need to wipe system and data? Wouldn't that wipe the whole OS?
I did the factory reset and want to wipe both caches... errr.. what's the button combination to boot to TWRP? I use "Quick Boot" before..

It can be done by pressing at the same time Volume up and Power buttons until the display lights up, which is when you have to release Power button, while at the same time you should keep pressing the Volume Up button.
If you wish to keep your current ROM DON'T wipe system.

If I were you, I would just backup everything and clean flash. That always fixes that problem. Also, they do have an 11/13 nightly up, try that out too.
First try going to System>Apps>Contacts Storage and clear the data and cache, see if that helps.

Be very careful then. Because clean flashing wipes EVERYTHING. So make sure you back up everything with titanium backup. Then go into your recovery and to wipe/Format data and reinstall

*****EDIT**** I just backed up my phone in recovery and I wiped it and restored, this error is still hapening
do a adb backup of your contacts and accounts then completely wipe device and reinstall rom
adb backup -apk -shared -all -f C:\nameofbackup.ab <<< this makes backup
adb restore C:\backup\nameofbackup.ab <<<< this restores backup that you made

[Q] Weird vibration that won't stop?

Really weird issue, don't know what causes it.
The phone starts vibrating like crazy and won't stop until I reboot the phone. It happens randomly, not too often but it's quite annoying.
Running stock, rooted 14.2.A.1.136. Anyone else experience this?
I'm sure you didn't wipe after any official sony updates. So I recommending you to Factory reset with full wipe.

Try to flash it clean 136 ftf. I'm sure is not a hardware issue
I experienced the same thing on the new Kitkat build. It started by itself and I had to reboot to stop it. It happened once and that was it. Never happened again.
