If this what you are referring then you really a sensitive one to me...hahahaha!

Just couldn't understand why required to factory reset when OTA from stock non-rooted ICS to stock non-rooted JB.

If you are from stock to stock there will be no data will be wipe and what it does is replacing your ROM to newest only

Unless, you installed custom ROM and going back to stock and vise-versa can simply go to download mode to wipe data and fatory reset.

LOL!    just couldn't understand.

Anyway! you are a good helper here can't deny  but too sensitive...

I guess -j-t- replied your concern but good to backup... 

i was from poland jb too and flashed to malaysia jb. for my case, it when well, but not well. after flashing, i couldn't shutdown my phone. instead of shutting down, it restarts. so in order for me to really shutdown i needed to take out the battery. so i did a hard reset. of course i back up using TB. then restore the user apps. but for the system apps, i use until something wrong than i make a decision to configure manually or restore from TB.i don't have a checklist on what need to be restored on the system, so i just use the "use until encounter problem" approach.

hope this helps. u may want to consult an expert but i am just like u, first timer. just handle the problems as they come. my phone is quite perfect now after 3-4 days of problem solving bit by bit.

in case u want to know the problems:
1. i get the "unfortunately......" messages.
2. my viber go crazy, my wife call me, but my girlfriend name show.
3. sync doesn't work properly until u delete and recreate your google account.
4. my old preference setup all back to default.
5. many more can't remember but its minor only the big ones are above.

Well, i flashed from ICS stock to Malaysia JB stock... feel not good with DLJ1, then flashed to Omega. Yesterday flashed to wanamlite and tried... today flashed back Omega coz like it more. (wanamlite is good also, just personal preference)

Im not a pro, but from all the flashing here and there... just follow the steps below, won't go wrong.

1) Backup using Titanium Backup (All users data and system data)
2) Do a Nandroid backup just in case anything happened during the flashing
3) ALWAYS wipe all data, wipe cache, wipe dalvik
4) Flash the new ROM u downloaded from SAMMOBILE or other custom ROM
5) Reboot
6) If u are flashing Malaysia stock ROM, root again
7) Restore using Titanium Backup. (FIRST restore missing apps with data. NEXT only restore all system data, select the one with GREEN colour only, RED might crash with your currect system, especially when u upgrade from ICS to JB.)
8) Reboot and you are good to go.

For your case, no need to unroot , just follow the steps above. Yeah, stock rom to stock rom

Yes..JB definitely better than ICS.
Just dont forget to do factory reset after upgrading.

Use Super Backup app for contacts..logs..sms..bookmarks..and your apps apk. Transfer the backup files to ext sdcard before doing factory reset as all files in internal storage will be wipe out clean.
Same goes to any other files such as music..videos..pictures.

when factory reset it will to the last (latest) ROM you flash into your phone. As per you mention above if you from JB Poland to JB malaysia..If JB malaysia install successful when factory reset  it will reset to JB Malaysia default setting. 

Just backup tb in intenal SD.. once complete the USB it to PC... Finish ROM installation then copy Tb backup to phone then go to playstore dl TB n install. finish install.. press option (then left key beside home key) select preference >Backup setting (Backup Folder location)> detect.

same ... better Factory reset once you flash to other ROM...for me once update ROM or Change ROM, I will Factory reset. to make sure my latest rom or app will be in default setting other wise you phone program is controlling you...(you Dun know why is this on or off or why its sync or why lag or why battery problem etc ets etc and etc  and give you this    )

+1 to wanamlite
else ARHD
nothing will gone
ARHD, wanamlite, checkrom
*checkrom is the lightest, remove all bloatware, and download back from their kitchen (see what you want only download)

when no JB ppl ask when got jb... got jb ppl wany ICS 

cons :
need download the things you want from kitchen app

got, don't worry

Just read this. It's an old article but i think it is saying just press the home button to exit the app. Let android handle the ram for u.

I know android is a geek phone. But normal users use it too. Telling normal users to install stuff to close app properly or telling them the right and wrong way of exiting an app make them scared to use android. I don't think Google wants that

That is what I do not want to do. I just want to open apps. I hate closing them and I feel it's not my duty to close them. It's the operating system duty to close. If I want to use another app I just open that app. Why do I need to close the current app? It's one extra step to me. Android is doing it correctly. PC is doing it wrongly

the answer is simple. Android aint no PC.

And I thought they are already there with Google. :/

@drumhitz polaris has been disappointing ever since I don't know when. It's sad to see a good app go to waste like that.

Well, for me, I don't think that they'd try to venture into the PC market anytime yet as the market is covered by mostly windows and mac only at the moment. Since they are doing great at the moment, they should continue to concentrate on Android. (For now that is.)

in pc, we have a paradigm where all your open apps are at your taskbar. we know since years ago we been unproductive and  not even aware of it. notice when we open too many apps, we will say "sekejap let me close all my unused app first before i open another one". why are we the user doing that? the paradigm we been living in all this while is the user manage the RAM. it should be we just open and open and open, if windows run out of memory is its pasal. windows should figure that out, not us! go and figure out which app we open that never use for so long and close it for me. but don't tell me its closed coz i don't want to know (its info i need not know). when i open it again, it should be as how i left it. whether windows open the app by bringing it back to RAM or not i don't care, as long as i get the see my app as i left it.

android way of doing things can also apply for PC. windows 8 knows that now, finally!

Err... is that any heard about 'project butter' for s3 my girlfriend ask me jor T-T

Haha yeah may be come true

basically it's a software lubricant

i got a problem with my s3. after i upgrade it with the official JB..when my phone start..it was going into SAFE MODE. i have read several solution and they said that have just to reboot it back. when i do so. my S3 is still in SAFE MOOD.

Please Sifoo...WHAT TO DO! T_T...

Yeah.. better wipe cache and dalvik.. standard procedure

1) wipe data
2) wipe cache
3) wipe dalvik
4) then only flash the new rom..
5) restore from ur backup..

just a few clicks only to wipe cache and dalvik, not even 5 seconds, its done.. so why take the risk for not doing it? I always do that when flashing new ROM..
