hello guys, i am using PA rom now, but i want to test another rom, but i have so much apps and so much configurations, is all in titanium backup but every time i install a new rom i must restore data for apps i want, so i was wondering, nandroid backup can restore all my files and even the rom that i was using? and about performance, when i want to go back to PA, is better restore a nandroid backup o clean flash and reinstall all apps?
and about the procedures is like this:
Nandroid of ROM 1
wipe and flash ROM 2
wipe and restore nandroid backup.
my question is about the correct procedure to restore, do i need to wipe data before?
i like to test s much roms but is so bad to take about 3 hours to configure everything when i come back to the i was before.
thanks in advance

Titanium Backup and Carbon(Helium now ) doesn't cause any issue due they restore only /data/data/APP datas
Wipe data is need (ALWAYS) over Rom switching for different Settings and Features, e.g:
AOKP -> PA : Full data wipe ( i prefer add wipe system due nightly script recovery that keep gapps ) + Restore Carbon is right procedure
Pa -> Pa: in theory you need only wipe cache & dalvik
Nandroid is evil, restore nandroid data backup is same of dont do anywipe due nandroid make image of data partitions, and reflash it
Nandroid is usefull only as backup ( data lost or nightly fail or something like this )
I suggest anyway over change rom , delete /sdcard/Android for new system base.
so use a nandroid is valid? no performance loss when using it?
i want to try codex rom but i already setup everything i wanted on PA and i dont want to flash codex, and if i dont like and want to go back to PA i must setup everything again. this is the main reason i don not flash roms to much. i few months ago i never stayed in same rom for a week, but now i am tired to setup the same things again.
so if i make a nandroid of my current rom, flash codex test a few days, and restore nandroid everything will be fine like was before?

Can someone explain a few things about backups and ROM flashes, please?
I've got a custom ROM on my Desire, and I'm using an Ext partition to hold my apps using App2SD.
I've run a full backup with Titanium Backup.
If I want to wipe and flash a new ROM, how does it work?
I do a factory reset, wipe cache, wipe dalvic.
I then flash a new ROM. New ROM will presumably be faced with the apps I've already got on my SD card ext partition.
Do they just install back, or do they cause problems?
If I reinstall Titanium Backup on the new ROM and restore everything, do I end up with new ROM and all my old apps back as they were before?
Or do I need to wipe the ext partition too, before doing a restore?
Any pointers would be great.

Doing a factory reset wipes all apps so if you do that before flashing the ROM all the apps will be gone from your ext partition.
You can then restore your apps using titanium backup. Be careful though, your market apps are fine to restore but you should be very selective about restoring system apps. I only restore data on the green coloured system apps to get back things like SMS, my custom sense layout, that sort of thing.
If you go from sense to non-sense ROMs then you may not even want to do this much.
I was looking to flash to Bakedsnack 1.8 with ROM manager, has anyone done this successfully? Or would you recommend doing it a different way. I ran the backup current ROM for the standard one that came with phone just rooted... but does that save EVERYTHING??
Yes, a nand backup saves EVERYTHING. Think of it like having a clone of your hard drive on your computer. If something goes wrong with your new ROM you restore a nand backup and everything is there.
Backing up through ROM Manager is fine. Make sure you do a complete data wipe and cache clear before flashing your new ROM of choice. If you don't do the data wipe and cache clearing you will likely end up going into a boot loop after flashing the new ROM. If that happens it isn't a big deal. You'll simply have to reflash the ROM, this time remembering to do the data wipe and cache clear.
Hey All,
I am curious about a few things...
I had a couple/few nandroid back ups that were stored on my phone, do you all only keep 1 nandroid and delete your previous backups?
I am running mikfroyo and flashed another ROM about 2 days ago, had some issues so I went back to mik. I think I may have done it in a way that nobody else does...I did it like I was flashing it for the first time, wipe everything and flash from sd card.
Should I have just did a nandroid restore? What does this actually bring back? Text, recent calls, apps?
When doing a nandroid restore should I wipe all before doing so? I would imagine the answer is yes.
And one more, before switching to any new ROM, should I always flash Caulkins Format All zip?
Thank you.
Nand restore will restore everything that was on your phone when you made the backup. Definitely a good idea to flash the zip when installing a new ROM. I also do it to restore though.
When you restore, unless you are backing up the cache, which isn't necessary, you need to minimally wipe the cache/dalvik before you restore. Also, if your SD Card is partitioned, you would need to wipe SD EXT. I pretty much flash Calk's format all anytime I restore or flash a new ROM.
I almost never have one back up. I have a few ROMs I like so, I set them up the way I want and restore between them when I get bored, which is like 100 times a day it feels like.
I do usually only keep the latest backup of any one ROM though. At any given time I probably have at least 5.
Edit: I re-read your post and I think I misunderstood one part the first time. Sometimes, when I got back to a previous ROM, I do just reflash it and start over, but I am anal about fresh starts. Usually I do just nand restore, especially if I know the setup was running well. I don't typically restore a lot between ROMs b/c I feel like it just adds to something that can go wrong. A lot of times I redownload apps instead of restoring, especially if they are purchased, since they are just stored in my apps in the market anyway. And I never restore app data. Usually end up only restoring about 30 apps w/out data, but most people do backup/restore a lot of info with no problems.
You should have just restore from a previous backup. When you restore, it bring ti back to EXACTLY how it was, texts, number of calls, ect. Actually you don't need to wipe when doing a restore. Well you can manually wipe all of them, or flash the format all, so I'm saying yes.
Also, I suggest against wiping data before creating a nandroid backup, lol. That would defeat the purpose, as your info and apps will be gone! Just wipe cache and davlik before a backup, or nothing at all, just so there's no confusion.

Yeah, I didn't mean to wipe anything before backing up. But if your going to restore a different ROM and there's no cache included in the nand back up you're going to restore, then best to wipe it before you restore.

It is partitioned, what gets stored on there that needs to be wiped, apps?
Thanks for your help

If the ROM has a2sd built in, yeah, if not, nothing. I always wipe it just so I'm in the habit of doing it for when it's there. Also depending on how a2sd is set up, dalvik can be on there.
I've been running CM 10, 4.1.2, on Verizon gn. Works fine.
But I can't leave well enough alone, and want to try 4.2.2.
That should be easy right, just flash the recent CM 10.1. No cache wiping. Right?
But if I do that and I don't like it. how do I go back? Is it as simple as just flashing CM 10?
Also, I have Ti backup. The backup folder is sdcard/TitaniumBackup. I've read that 4.2.2 creates /sdcard/0/ for data. Does this mean that my present backup will be deleted?
Any help appreciated.
Since you are migrating Android versions, I would recommend that you do a full wipe, so system, data, and cache (and restore apps from TiBu if you must). You can do a nandroid backup from recovery; if you don't like 4.2 just restore it. When restoring a nandroid backup everything will be exactly the same.

I just upgraded from 4.1.2 to 4.2.2 and had the same concern about being able to go back if I had problems and knowing that the partitioning of internal storage would be changed.
I recently got my GN back from Samsung after getting the screen replaced. Before sending it off, I totally wiped and reset the phone to stock. I made sure I did a full Ti backup first, then a Nandroid backup, and finally copied the entire contents of internal storage via "adb pull" to my desktop computer. When I got the phone back, I reversed the process and was able to restore the phone entirely to where it was before the wipe.
I did the same operation before upgrading to 4.2.2, without wiping the phone. So if I'd have wanted to go back to 4.1.2, I'd have wiped the phone, including internal storage, and restored as described above. I'm pretty confident that this would have removed the new partitioning from 4.2.2 and reset it to where it was before the 4.2.2 upgrade.
Sorry to be dense, but...
So I do a nandroid backup from TWRP 2.4.4.0, system, data and cache
From TWRP flash the CM 4.2.2.
Do nandroid restore from TWRP?
Flash gapps, restore apps from TiBu.
Now if want to go back to 4.1.2:
Flash 4.1.2, wipe system data cache.
Flash gapps, restore apps from TiBu
Do I have this correct?
Nandroid the entire thing from TWRP, wipe system, data and cache from TWRP, flash CM10.1 and gapps from TWRP, restore apps from TiBu in ROM. If you don't like it just restore the nandroid from TWRP. TiBu only restores apps, nandroid restores everything: ROM, account, system settings, apps, etc.
The only extra thing I referred to was making a full copy of your phone's internal storage to your computer using "adb pull". This would allow you to wipe the internal storage and restore it, in case the partitioning change from "/storage/sdcard0" to "/storage/emulated/0" needed to be removed. But if TWRP's nandroid backup and restore takes care of this, this step isn't necessary.
How easy? Dead easy.

Hi guys. I'm using the 2.6 version of TWRP. It seems whenever I restore a backup things always seem to go wrong and the OS reboots the first 24-48 hours before things are eventually stable. Do I need to factory reset and wipe system, cache and dalvik cache before I restore a backup, or should restore simply take care of everything for me already when I'm switching from one ROM to another?

One of the reasons I don't backup.
But, yeah I suppose you would want to clear data and cache before you flashed a backup.

You should always wipe cache, data, system, dalvik cache and do a factory
reset before restoring a nandroid backup or flashing a new or different rom.
Doing a factory reset before restoring a nandroid backup will not make
you loose anything at all because the nandroid backup contains all your
settings, apps, mms, contacts and anything else you had in your rom
prior to making the nandroid backup.
It would also be best if you went to the play store and download the free app
"Goomanager" and use that to make sure you have the latest version of TWRP
for your phone.
Good luck!
