Just flash one of Chainfires CF-Root kernels through ODIN and boot into clockwork recovery then run the Clear Dalvik option. Job done.

But of course you no longer have stock as you have changed the kernel .
Update would have wiped it anyway .

JJ is correct, if it was an official update through kies then don't worry about it. I would only bother about Dalvik if you start to get flash happy with custom ROMS.

cheers guys, i guess if it wiped during the flash then no worries

Best way to flash back to stock rom?

What would be the best way to go from any custom rom back to a stock rom. Wipe data, cache, dalvik cache in recovery, the shut down phone and flash stock rom via odin? Or should I also wipe system before flashing?
Thanks!

You don't need to do any wipes through CWM if you are going to be flashing a stock Odin rom, odin automatically takes care of all that stuff. You can just boot your phone into download mode as is and flash the odin rom.
Regards.
Btw, your title is a bit misleading/ confusing? Aha, you ask "best way to flash back to custom rom" ??
Yes that was indeed a bit misleading, corrected!

Updating to new firmware/kernel

Hey all so after I update my firmware to XWKK5 do I have to wipe everything while in recovery mode is it really necessary?
What do you want to achieve with deleting all from recovery?
If you've upgraded, then the phone is in the version upgraded. If you delete all from recovery, you have to reinstall the entire ROM or the phone wont boot...
Thought I had to Wipe Data / factory reset and Wipe Cache Partition?

Instructions are to be followed .
Custom roms usually ask for wipe but not stock roms .

You don't need to do that if you are upgrading from a Stock ROM. If you chose the wipe version of ROM for flashing then it'll automatically wipe you device. If you use non-wipe it'll upgrade and everything remains same.
Wipe is only recommended when you are switchin from Custom to Stock or vice-versa else after a version downgrade say KK5 to KJ3.
Hope it helped.

[Q] How to remove a ROM so I can flash with a different ROM?

I flashed my S2 yesterday with CheckROM and I like it and everything but I'd like to try MIUI today but I'm not sure how I would go about this? I think I may have to wipe my phone (already have a backup from before I flashed with CheckROM) and then just install MIUI like I did CheckROM? Correct me if there is another way or I'm wrong.
Just go into clock work recovery, wipe data cache, flash miui.

By formats system do you mean wipes everything or just cache?
Let's see.......
You wipe data, cache but your phone can boot, because the OS remains.
You wipe system OS got removed, you can't boot phone.
Wiping system is the cleanest flash you can do.

[Q] Rookie question, struggling to find the answer

Hi folks,
Bit of a rookie question that's always been a mystery to me on Samsung phones.
When you install a completely fresh stock rom via Odin, does it wipe the cache partitions also? Like a total clean wipe.
Usually I would just go into CWM and do it from there but i''ve been keeping it all stock until the final version of Jellybean comes out.

Yes stock Odin flash is really the same as a wipe or format .

[Q] My SGS3 Started to be very slow and laggy

I use stock rom (original) I9300XXEMC2
Kernel 3.0.31-1042335 [email protected] #1
Android version 4.1.2
My phone started to be slow and laggy. When I get a call it takes about three seconds to recognize the caller. I get alot of apps crash, I mean apps suddenly closes(I started to play a short video and then 3G Watchdog and PlayerPro got close).
What could be the reason for the laggs and slowleness of the phone?
Your rom has the sds fix so it might be the fix kicking in to save your phone. First try clearing cache and dalvic in recovery and fixing permissions, if still laggy then factory reset.
what does clear dalvik and catch do? do I need to backup the phone before I do this things? (I'm not talking about the reset only clear)

It clears the cache and clears the dalvik for details use Google but Dalvik is basically VM .
Backup is not relevant to either both are rebuilt on next boot .

ADVANCED.

I don't have advanced...This is the options I have:
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
apply update from cache
You need CWM recovery .
Use Philz from development .

I use rom stock and original kernel I also don't have root.
Is it possible to do it without root and without changing recovery?

If you're not de-odexed (which you won't be since you're not running a custom ROM) there's not a lot "Wiping Dalvik-Cache" will do. Dalvik-Cache is used when you have dispensed with odex.
Essentially, every app you have has an .odex file.
so:
/system/app/MMS.apk
/system/app/MMS.odex
Most custom ROMs are "de-odexed" which means they get rid of all the .odex files and replace them with dalvik-cache files.
Basically what I am saying is you don 't have any to clear.
I wrote that I use stock rom so I don't want to root my phone.
don't suggest things that can't be done or I don't want to
Anyway thatks
I didn't. I told you it's irrelevant.
All you can do is factory reset or flash official roms. Or dummy file generator.
Just read "unusual freezing" thread

Guide to recovery mode on youtube:
Search for:
"How to Wipe Galaxy S3 Cache Partition"
Didn't lose anything.
Still have the problem. Now it also sometimes restart itself.
Any other solutions except root & wipe?
Factory reset .
Still a problem then a service centre is required .
