Hey guys quick question when I restore a nand backup do I wipe data, catch etc. before or after?

No need for a nand restore. They are replaced by the restore nand.
If you want to correct problems do a wipe of cache & dalvic after the restore but only DATA as a last resort, after you try booting & then you NEED ReRecovery . Flash it after any data wipe or rom flash-see my signature link.

I have a quick question. I'm in Joelz 2.3.3 at the moment but I've been wanting to try a 2.3.4 rom. So i've been wondering, when flashing to one. What all do I have to update and how? I believe change the name to PGsomethin and let it update through hboot? Then do I delete it or keep it on the card? And when flashing back to an 2.3.3 Rom will everything be okay?

Rom's come in a zip format. Boot into recovery (use the 4 in 1 or an app such as quick boot) once in recovery wipe cache and davlik cache at a minimum. You may need to do a full wipe of data, cache and davlik. Or you can use a tool like superwipe which reformats boot, system, cache, and data partitions. Usually a wipe of cache and davlik works as long as the ROMS have a similar base. Once that is done select flash zip from sd card, then select the zip of the rom you want. Then flash that sucker. when it is done it will tell you, then go back a couple menus and reboot. Presto you're done. The first boot after a davlik and cache wipe may take a while so be patient.
Once you are done you can delete the zip from the sd card.
If you are going from 2.3.3 to 2.3.4 you may want to flash the radios from 2.3.4. the ROM thread should have this info if required or recommended.
Going back to 2.3.3 is just as easy just put the 2.3.3 ROM on the card and flash that in the same manner.
Word of advice is to always make a nandroid backup, its under backup then usually choosing the boot, data, and system partitions will suffice. This way if you do something that totally borks the phone you can volume down and power to get to recovery then restore the nandroid and you are right back where you started no harm no foul.
Good luck. Also if you check the wiki's most of this info is in there if you need more detailed instructions.
Thanks

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:

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.

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 .
jje
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.
How to restore a nandroid backup as exact state when I backed it up ?
I restore Nandroid backup this way = in TWRP 2.8.5.0
1. Wipe Cache
2. Wipe Dalvik Cache
3. Factory Reset
4. Restore Nandroid Backup
5. Wipe Dalvik Cache
6. Reboot System
7. Stay some time in Manufacturer boot screen
8. After 2 -3 mins, starting to bootloop.
I am restoring backup stock over stock. Never installed Custom ROM.
I brick my phone by installing some MODs I made myself or by some other developers. (Like XtremeMusic MOD bricked my device etc.).
Well. I can get back my phone at working state if I wipe everything. Wipe everything before restore and Dalvik Wipe, Format Data , Factory Reset (This is compulsory otherwise welcomed with bootloop) after restore in a order to restore Nandroid at my phone.
Well. This won't bring back my phone at exact state I backed it up.
So whats the fix ?
