Hi yesterday I flashed the stock 4.1.2 update to my rooted s3 and I had expected to lose all my data and apps so I backed everything up with titanium ready to restore it after the update, surprisingly I didn't lose anything after flashing.
I was just wondering if I was to flash cyanogenmod 4.1.2 would I lose all data and apps this time?
Thanks

No - all your data/apps will stay unless you do a full wipe/factory reset in recovery.

The data will remain, but it is a granted prerequisite to flashing that one must do a factory reset before flashing a new rom. Note: this applies only for a new rom altogether, not updates to the same one!

If I helped you, please hit the thanks button!
You won't lose your apps/data unless you do a wipedata/factory reset . Also some roms pre-request a full wipe in order to the rom to boot .
Wipe may be asked for by the rom maker to avoid conflicts and stop users posting my app stopped this rom working .
Rom may be a wipe rom but not usually .
Personally i never full wipe unless problems but do wipe cache dalvik and system only before any instal .

So technically should I be able to flash cyanogenmod without doing anything but wipe cache and davlik cache?
Thanks again for the help

yes, you should be able to.
if you encounter any problems then a full wipe is recommended.
I'd back up your apps/data just in case.

Hey guys, quick question. I am currently running CM7 on my V but it is to unstable for me, too many FC's and reboots. I would like to flash That Ain't Sense ROM, found here:
http://androidforums.com/optimus-v-all-things-root/312747-rom-theme-wait-aint-sense-4-6-2011-a.html
Under the directions, it says:
how to flash:
put gapps and rom on sdcard
wipe the hell out of your phone
flash both and reboot
enjoy

When it says, wipe the hell out of the phone, what specifically do I have to wipe, and at what time during the process? Since I am moving to an entirely new ROM, what do I need to wipe?
P.S. I am running thunderc recovery.
Data, cache, system, dalvik cache and something else i can't remember. If am i not wrong, ROMManager doesn't work on the V, so you can't switch back and forth freely, unless there is another method.

You wanna wipe before flashing a new ROM. I wipe data/cache, then Dalvik cache then flash ROM, then gapps file

Is that all I have to wipe? I made a nandroid backup but I just want to make sure I'm doing this right.

This should be in Q&A
That's all I wipe. Wiping everything won't hurt though. Just don't do a factory reset through the settings with the phone booted up. Do it through the recovery.

How can i do a full wipe like when i got the new phone? I tries to wipe cache and data, then factory reset.. but some of datas are not backed up!! My noticed issues : vold.fstab and vold.conf, my custom kernel also. So how can i do the perfect wipe? Please help... thanks !!!! Im using samsung galaxy s2.
did You try to do factory reset by code:
*2767*3855#
If I wan't to have a really clean system I install new stock rom and make the factory reset by code. Everything is cleared after this

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.

Hello guys,
My question is what the usefull solution for backup and restore the rom? CWM backup / restore seems not really working well. Xda and custom rom's dev always remind to make a backup, but when u face a problem after flashing rom, you cannot access CWM if you got bootloop, then how to restore? And if you dont like the custom rom that you just flashed for some reason, you might want to restore back to your 'fav' rom.. but unfortunately it's not work as you thought. Sometimes restore failed. Im looking the solution for this..
-restore / backup anywhere without using pc.
-not reflash the rom, this will need to customize it again.. Hassle.
-any android app or android system ability to handle this. If CWM can handle this, then tell me how to restore when u got bootloop and cannot access the recovery mod.
-if there's any other app or method, please suggest them to me.
Any help or idea will be appreciated. Thanks.

When ever Ive made a backup Ive always booted to recovery,"backup and restore" and then "backup".That gives me a full Nandroid backup.As far as the bootloop goes Ive never had a problem to boot to recovery with the 3 button combo.If the 3 button combo works,and its never failed for me then select "backup and restore","restore".Ive also read that reflashing your kernel can solve the problem.I know a simple factory reset can,but not always.
nandroid backup is the best
You can always restore the rom when you can access the recovery mod. If you are a flasholic, you cant escape from bootloop and no recovery mod. My odin binary counter now up to 539.. Nandroid backup sometimes got problem.. Let say i made a backup a checkrom, the i flashed miui, suddenly miui got problem, and i get into recoverymod to restore back my checkrom.. When u done restoring, you will be in checkrom but this time its got many problems. Flashing compatible kernel will not solve the problem. The only solution fot me is to reflash it again.
Im not looking for this way, reflash the rom is hassle, sometimes u got bootloop and cant access recovery, then u need to get back home to use computer with odin to flash only kernel.
What else backup method other than nandroid backup.

Normally when I flash a ROM over top of another and I know,from other threads,that they are not compatable in terms of insalation and basic use(FCs)then I always do a full wipe (format system/data/cache,battery stats and fact. reset) prior to instalation.With Titanium it only takes a few minutes to reinstall my apps and during instalation there is no conflicting data between the old and new ROM which would cause a major failer to occur.Thats why if something happens the 3 button combo always works cos nothing major has happened.A factory reset and Im done,althought very rare and the nandroid backup is still in the SD if needed.The problem is when there is to many ROMs cluttering the devices system.Ive read that flashing over top of CM7,Lightning and Miui can sometimes be problamatic.

Ahaaa! Your description attract me, i think you're right, base on the way you explained about full wipe does make sense to me. The real interpretation of 'full wipe' is including formatting the system?
Maybe I'm doing it wrong here, flashing another rom on top of another. What usually i did is 'full wipe'... This is my step :
1 - clear data/factory reset
2 - clear cache
3 - advance > clear dalvik cache
4 - flash new rom
This is what i did, i didn't format anything as you mentioned above. Is your full wipe method lead to 'fresh install'? Well buddy, could you please note down your full wipe method step by step including format the system? Which step should i do 1st and what step next? Could you?
Thanks, highly appreciated.

Cool.The thing is not all ROMs are compatablie and therefore can cause problems between each other.Your phone holds data from the previous ROM and also your battery collects info and data from each ROM.All this data and info if not cleaned up (and if from various non-compatablie ROMs) will most likely always result in problems.A full wipe,that I will write below is like installing your ROM on a completely clean devive.First of all a nandroid and titanium backup which i explained ealier,I think?
1.Pass the new ROM to internal-SD
2.boot to recovery and wipe cache partition,dalvik cache,battery stats(go back)
3.select "mounts and storage"
4.format cache,system and data (go back)
5.now wipe data/factory reset and your phone is now completely clean
6.now just install your ROM from the internal-SD as normal and I also do another factory reset to avoid possible bootloops and reboot device but if you get one pull the battery or use the 3 button combo to do one.
this full wipe will clean up all system data but will not touch your SD card so your titanium and nandroid backups will not be touched if you should choose to use them.Once I reinstall all my apps again with titanium its a good idea to reboot to recovery and wipe cache partition and dalvik cache then reboot phone.This will help avoid market connetion problems.

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
http://forum.xda-developers.com/showthread.php?t=1700211
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.

Can I Flash from one custom Rom to another Custom rom WITHOUT FACTORY RESET WIPE. so I dont loose my programs and settings?
I would like to keep flashing Furture custom roms But I want to Keep ALL my Settings and Programs.....So I want NO WIPE FLASHABLE ROMS...:silly:
Any ideas?
I wouldnt.
But u can always make a backup. Test the new rom. If u like it keep it and start over. If not. Recover backup.
Also titanium "backup" will backup your apps.
U can sometimes just wipe dalvik and cache. And fix permissions. But its not advised. Red through you rom of choice install instruction. If it says full wipe. And u dont wnna full wipe. Dont.
U dont need to full wipe when updating a rom. Jus moving to a completely new one. I.e going from omega to cm9. Will require a full wipe. But the roms thread will tell you this.

Ideas yes Bumping posts in a short time span is against the rules .
Answer not many custom roms actually ask for Factory Reset and Wipe .
Worth reading each custom roms install instructions in full .
Where a custom rom does ask for the rather unusual Factory Reset and Wipe it would be for a significant reason But you are free not to factory reset install the rom and see if it works or not .
