So my phone is a little messed up so I want to completely restore it to factory settings. Just want to make sure I am doing it correctly with the steps outlines below:
1. Back-Up current ROM/kernel with Nandroid back-up.
2. Back-Up all apps with Titanium Back-Up
3. Delete /data
4. Follow this guide to restore to original state by downloading the correct files and flashing via Odin: http://forum.xda-developers.com/showthread.php?t=1113928&highlight=stock+roms
So is it going to be okay if I wipe /data and then flash with Odin? I want a completely new fresh installation, and then I can recover everything and root again at the end.
I think you forget doing the wipes before flashing the new clean rom with Odin.

Well isn't that why I should delete /data?

OK, I am pretty much completely new to android and have a few questions if someone has a few minutes.
1. Ok, first is titanium backup. When you do a ti-backup, is it a complete image of how your phone was? I did a backup before perm-rooting and then did a recovery after. I did not have contacts and a few other things I did before. BUT, after a "crash" and reboot, those things re-appeared? So I am guessing it is supposed to be a complete image of the way the phone was?
2. next, can you use the same ti-backup file no matter which rom you are running? So if I backup now, flash new rom, then recover will it work? Or would it fail from trying to restore something that isn't available in the new rom?
3. Nandroid backup. Is this just a backup of the actual rom? or is this an actual image backup too?
I will stop there for now, thanks for any help.

1: Titanium backups only apps and the data within the apps.
2: Yes
3: A nand backup will backup everything that is in your phone.
The system, cache, dalvik cache, wimax and some other stuff. When you want to backup everything that's on your phone, you do a nand backup. If anything goes wrong with a ROM you installed. Yo do a compete wipe and flash your nand backup.
Appreciate my help? Thank me
Thanks, that helps.

Good, I actually did.
Appreciate my help? Thank me
On my stock rooted ROM, after wiping data, cache and dalvik cache, I've created a Nandroid Backup.
My question is, if someone restores this backup to there phone, which is the same as mine, will it have any of my information, or could it possibly cause any problems?
I was simply going to upload it, so that if anybody has any problems installing the latest OTA or hasn't got a working Nandroid backup, they can use it.

Em well first off, if you done the wipe data ect first then you will not have a NANDROID Backup as there is nothing there to back up,
Second i wouldn't recommend anyone but yourself use the back up but if its between friends ect from with in the phone in settings go to factory reset and that way your data will be clear for the most part and safe to share with friends you trust in-case anything is left behind but i would not release to public in any capacity and then proceed to create your NANDROID backup from within your recovery app.
If you really had to do it that way, you would want to create a NANDROID backup for yourself, reboot your phone go to settings factory reset, then boot back to recovery make another NANDROID Backup (This one for Friends clear of your data)

The whole point of me doing the wipe data etc first, was to clear any personal data from the phone.
The Nandroid backup was so that there was a working stock rooted rom.
My question should have been does it keep any data that cannot be manually deleted. e.g. Serial numbers etc....But I think I found the answer. Apparently it does and it can cause problems when restoring.
The only reason I was going to do it was because, I have seen a couple of people using the HTC One X, that are trying to get from stock rooted 1.26, to stock rooted 1.28 and this backup would get them there.

If you take the boot.img and system.img from your backup and then use dsixda's kitchen to create a flashable rom.
dsixda's Kitchen Here - h t t p ://forum.xda-developers.com/showthread.php?t=1227549
(remove the spaces, can't post links yet lol) its the download and tutorial
There should be no information or data in your output rom so anyone can use it etc
hello
how can I clean my SGSII ,phone SD, and external SD card from old installation files, folders,. Bla bla bla
now I have my ideal settings , ROM , everything ,
is there any way to format everything then restore CWM backup ?
thx
Backup everything (Ti, Nandroid, calls, sms, etc). Format cache, data, system & internal sd card in CWM. Flash stock rom in Odin, CFRoot to get CWM, flash rom/kernel of your choice. Then clean install your apps from Google Play/wherever you got them from (preferable) & restore calendar/contacts from Google, & restore call/sms log with whatever app you used to back them up (provided this app only backs up/restores the logs/sms themselves & not the apk like some of these apps do). You could also restore your apps with Ti (not system apps) but if you do, don't restore data.
That will give you a clean start.

can I transfer the CWM backup to PC , then transfer it again to SD card after installing ROM, and restore the CWM backup ?
btw I have two CWM backups and I'm unable to restore one of them ,.it stock on " checking MD5 sums" for a while then phone boots without restoring anything
Of course you can. But what's the point of doing a clean install if you're going to restore a Nandroid which is a copy of your setup at the time you took the backup ? Kinda defeats the purpose. If you're having problems which you think are as a result of having a lot of crap on your phone; easy to happen if you haven't done a wipe for a while/have flashed a lot, if you restore a Nandroid you're going to have the same problems.
Personally, I do the steps I suggested every 4-6 weeks (instead of flashing stock after I wipe everything I normally flash CM9 Resurrection via Odin & go from there). I find it's an hour or two well spent. Phone runs much better after.
Up to you which way you want to go tho.

Hi,
4.2 of Jelly Bean update could be imminent for my Nexus 7, and I'm wondering about what and how to backup before the update. The question I think is a general android one though... which is why I'm posting it here.
This was going to be a question about factory reset... but reading other posts I think I now understand that factory reset just deletes data/cache, so I think any time you do that it's just gonna return the device to a clean ROM state without changing the ROM. (whatever flavour/version ROM is)
When a ROM update is applied (either official or manually flashed), I guess it wipes everything, is it like a disk format or something like that? I have installed CWM recovery and rooted my device, I think the update will unroot it, but will the CWM recovery still be loaded?
And then, what backup should I take before the update... I think a Titanium Backup is a must, I understand how that works. But a Nandroid backup too? Or is that more like taking a disk image, would that be useless to restore after the ROM has been updated? And if so, does that mean any old Nandroid backups should be discarded?
Once the new update to 4.2 is installed, is it advisable to take a Nandroid backup immediately, or better to download the stock 4.2 image and keeping it as a starting point? (does this amount to the same thing?) I guess this is where a factory reset would return it to stock (providing I haven't moved anything to the system apps)?
Or is it possible/better to use a Nandroid backup as a point in time image of everything that's been installed on the device after adding back all the apps etc? I guess that leads me to wonder if the Nandroid backup is needed at all if I'm going with the Titanium Backups...
Thanks a lot and sorry for the lengthy question, I've seen many posts touching on this

1. OTA updates should let you retain your apps.
2. Clockworkmod will still be installed following the update.
3. Nandroid backups are like a system image it makes a backup of everything on your phone (Minus sd card external) at the exact point in time when you make the backup. If you restore the backup it will restore your phone to the exact state it was in when you made the backup. You only need to keep a couple of your recent nandroid backups on your phone.
4. After the 4.2 update you can either make a backup or use a factory restore image it will make no difference. Factory reset would return it to stock.
5. You can use nandroid to make a backup after you install your apps in fact I would recommend this that way you have a convient restore point. You can also backup your apps with titanium backup.
Hope this answers some of your questions .

Excellent, thanks for the fast reply, you did answer my questions!
I was misunderstanding then about the 4.2 update, thinking it was equivalent to flashing a new ROM... you clarified it for me, seems it's less severe than that.
I think I'll go with your point 5 to use a Nandroid image for a convenient restore point after the OTA happens
i have unlocked bootloader, installed custom recovery by NEXUS prime, rooted my phone
Now i want to know if install the the custom mods of apps ,toggle panels etc >>
q1- how to uninstall these customs mods??
q2- when i do factory reset what will happen do these custom mods changed permanently in my stock ROM???
q3- before installing anything i have been suggested to make recovery of that, now how can i make recovery of toggle panel or icons??
1.: Generally, there is no uninstall method. Workaround: Make a nandroid backup prior to installing and restore that backup for uninstalling.
2.: A Factory reset just wipes your data, cache, dalvik cache partitions. The mods you mean are installed in system partition.
3.: Do a nandroid backup after you installed the mods as well, so you can restore it anytime you want to have it back.

A nandroid backup is one of the most important things with custom roms.
In CWM and TWRP there is a backup option that will make a backup of your whole phone. So if you restore it later it will be the exact same as when you made the backup.
