do a factory reset, clean cache partition, clean dalvik cache,format cache data system and sd card in cwm recovery. but do a backup first with titanium backup.
Wipe data/factory reset
Wipe Dalvik-cache
done!
You will also need to flash a stock Kernel if you are using a custom one.
Also if it is for warranty purposes make sure you flash a stock firmware too. They can all be found with a quick search.

Omg omg omg.. pleeeease someone help me.. I tired flashing a rom (phone already rooted and using cwm 5) for the fifth time and it's now stuck in startup on android (in white letters). I wiped system cache dalvik but nothing... what else could I try?
Which ROM are you using?
Try flashing again, and remember to read the instructions very carefully.
Wipe data/factory reset, wipe the cache (although that should be done when you factory reset) and the dalvik cache.
If it still fails, restore your previous backup (you did make one right? It's, like, almost necessary to backup your current ROM with CWM before doing anything, even if it's just wiping the dalvik cache. It's ESPECIALLY necessary to do one before flashing a ROM).
If all else fails, flash a new firmware using ODIN.
Thanks for the quick reply but I managed to fix it already.. I am awesome *big smiles*
You are awesome. Great job.
Hello. So i am on the Omega ROM v5.1 and wanted to confirm in regards to updating the same ROM or flashing a new ROM. After researching the site, I was able to get the information that:
1. Updating same ROM: All that is needed before installing via recovery is a cache wipe and a dalvik cache wipe right? For example updating to Omega v5.1 to v5.2.
2. Flashing different / new rom: You need to wipe cache and dalvik cache AND do a factory reset / data wipe.
Please let me know if I am correct in both 1. and 2. situations. Thank in advance for all your input!!
yes you are right that is what iv always done unless del recommends a full wipe . updating on omega you should be ok just wiping dalvik cache and battery stats iv always done it like that unless changing roms then wipdata factory reset is used as well good luck

Thanks soo much for your reply!! I was pretty sure i was correct, but wanted to double check so i dont mess this expensive phone up
Hello. I have backed up my stock rom and would like to flash a new custom rom. Team Win Recovery is all new to me as I used clockwork recovery and Amon RA on my old evo 4g. Before I flash a new rom, I know I'm supposed to wipe cache and dalvik, but do I also wipe system? Thank you for your help in advance.
If you're flashing a different ROM all together, then I usually do Factory Reset, Cache, Dalvik Cache. (in that order)
I don't know that the order matters, it's just my way of doing it, and I've never had any problems.

Thanks for your quick response. Gladly appreciate it! But there's also an option in the wipe menu to wipe "system". In the wipe menu, there's: cache, dalvik cache, factory reset, battery stats, rotation, system. I wiped cache, dalvik and battery, anything else I neeed to wipe before I install a custom rom? In clockwork recovery, all I used to do is wipe data, cache and dalvik.

Yes, when flashing a fresh ROM wipe EVERYTHING, including system. I usually wipe a few times just to make sure I'm starting fresh. I haven't used this super wipe but you can also check this thread

Edit: I don't usually worry with wiping battery stats or rotation

Thank you. I wiped everything and performed a factory reset.
You don't need to wipe system. Any decent rom out there will wipe the system for you before the rom flashes.
If I'm not mistaken, I believe that the factory reset wipes system anyway.
No factory reset does not wipe system. Also do not use super wipe zips. They are bad for you

Factory reset wipes the data partition. It does the same thing as the factory reset within the phone settings. If you wipe system, it completely wipes out the OS, and there will be nothing to boot. Of course you can still get back to recovery. When you flash a rom, by default it should wipe the system for you and replace the system with the rom you are flashing. There may be a case where you are flashing an incremental upgrade, which will not wipe the system.
The reason you do a factory reset (data wipe) when flashing between roms is because settings and other stuff that was saved on the data partition may not be compatible with the rom and cause issues.

Based on what?
Based on what developers have said. Super wipe originated from a CWM issue back on the EVO 4G and people never seemed to of forgotten.

The issue was with cwm not superwipe. The superwipe created for this device works fine.
the issue was with cwm, the superwipe was made to combat that issue. a good dev will set his rom to wipe system. all a user has to do is factory reset in recovery. Superwipe is a unnecessary step and could be bad for the phone if its corrupted or the person who made it did it wrong.
really great info, thanks guys!

Yes. A system wipe doesn't affect recovery. It just wipes the system partition on your phone. The recovery partition remains unaffected.

Hi everyone !
As a new Android user, I'm in a need of help... My GS3 is running Omega 8.1 (not sure of the version...) and I've tried to install the battery fix thingie but now I an't start the device anymore.. It's stuck on a screen and I can't do anything about it. Tried CWM recovery mode to restore a back up I've done before but it says it can't mount /sdcard or something like that...
Is my phone bricked ? Is there a way to rollback what I've done and save my datas ?
Thanks for your help.
Here's a screen of what I have when I start the phone :
Boot into cwm, wipe data/factory reset, wipe cache, then advanced, wipe dalvik, then try restoring

Thank you very much, it worked !!
Can someone explain why on some Roms you got bootloop after wipe data/factory reset?
I got this on Clean'N'Tweaked and Original Xperia T ROM?
What 'vital' files are in /data partition to cause this?

Because you wipe the system so obviously the Phone cant boot.

wipe data doesn't wipe /system, only /data and /cache.
Also I got bootloop even when performing from Settings -> Backup and restore
I think that rom's have Small Apps.
Small Apps need some cache,almost all two zip's mod need to install part 1,clear cache,reboot,then inatall part 2.
That's why after wipe some roms that includes Small Apps or other 2 zip's mods won't work.

Wiping data/factory resetting the handset wipes the system, just wiping the caches does not.

:what:No... Wiping data /factory reset doesn't wipe the necessary system files required for some ROMS... :sly:
There's a different option in recovery to wipe system

this^^. wipe data/factory reset from cwm does not wipe /system.
Do u wipe data just after installing without booting even once?
Sent from my Xperia Mini Pro using xda premium
Hmmmm....The BIG questions is.....Do you wipe/factory reset after flashing custom roms or before flashing custom roms???
if you wipe/factory reset after flashing customs rom then YES you will get bootloop in certain custom roms....if you wipe/factory reset before flashing custom roms then NO you won't get bootloop....
you should also check if the kernel you use is compatible with custom roms you about to flash on your phone....you need flash custom kernel first (using flashtool) before you flash custom roms using CWM....
OK Thanks for the answers. Maybe small apps are caousing boot loop
But I have another question: How Xperia T users using stock Rom when they do factory reset don't get boot loop?

Factory reset can solve the bootloop problem when we flash one ROM over other...
Factory Reset doesn't cause bootloops...
It just wipes the non-system apps and stuff...
Flashing a ROM with different framework over a ROM (like flashing CM over stock based ROM or flashing ICS over GB etc) , without wiping data /factory reset can cause bootloops...
Although there are a hundred other reasons for bootloops but it's the major one
Iknow , its very late ( 4 years ) lol
but its because of framework-res!
if U flash zellycream rom and reset it ----> every thing normal
install small app on stock rom and after reset---> BOOTLOOP
Sory for my bad English
