Noob question about reverting from custom kernel - Samsung Galaxy Tab Plus

My GT7+ has the LB2 firmware. I have not seen any copy of this firmware for downloading. Therefore I have been cautious and stick with the stock kernel and FW.
I installed garyd9's CWM and made nandroid backup. I want to try garyd9's custom kernel, but I read the warning on his post about compatibility with some firmwares.
I wonder if I flash his custom kernel and it fails, can I revert back to my stock kernel through nandroid restore?
Thanks.

Nandroid backup is a complete backup of your phone. When we say complete, it means everything on your phone – your apps, data, your current ROM and even the kernel. It is like creating a full system image of your phone that can be restored later, when required. - Restore from a Nandroid Backup via Recovery:
1. The first two steps are same as above. Boot into Recovery and navigate to the Nandroid screen.
2. Select ‘Restore’ to start the process. If you choose the ‘Advanced Restore’ option, you can select which component of the backup to restore – like the boot, system, data or cache. 3. Reboot system. Your system is now restored and is exactly same as the time when the backup was taken.-- Backup and Restore Using ROM Manager:
If you think the above process was easy, backup and restore through ROM Manager is even easier. ROM Manager automates the whole of the above process giving you the option to do these operations with a single touch. Just choose ‘Backup Current ROM’, enter a name for the backup and the phone reboots to start the backup process. There, your backup is complete. To restore, launch the app and select ‘Manage and Restore Backups’. Select the backup that you want restored and ROM Manager will do the rest.
You can delete or rename the backups as well.

Thanks for the reply. Now I feel more comfortable and adventurous.
BTW, I see that there is no copy of the official Samsung LB2 firmware floating around. I do not know how to make a tar file for the firmware / ROM, but would anyone be interested in a nandroid copy of the LB2? I can reset the tablet, go to CWM to save a nandroid copy of the default firmware, then restore my own running copy.

[Q] How to backup my software?

Hello. Currently, I am using RCMix S 2.7 and i thinking this is most stable and great rom for Desire S. I setup my mobile(applications, widgets, settings). However I would like to test new roms. How I can backup my customized software? I did backup in ClockworkMod Recovery and size of my software is 1.05Gb. Is this enough? How to make restore? Do i need to choose only restore or format something first?
Use Google sync for your Contacts and Calendar items (HTC Sync + M$ Outlook is also a good combination but you can use it only on Sense ROMs)
Download and install free Titanium Backup from the Market to backup your applications and settings (you can backup even your homescreen arrangement (all shortcuts and widgets) and restore them in one click. The backup itself is not taking too much space. My advice is when switching to ROM with different Sense/Kernel/Android version do not restore setting, it can mess up your new installation, restore just the apps and take the time to configure everything again.
I also test new roms all the time. My technique of back up is this.
1. contacs = back up using google. sync with your google account.
2. sms = i use 'kAmMa's BackupSMS'
3. Application = I only backup downloaded apps using Astro file manager.
For me titanium back up is a bit complicated.
to restore i always do this order
first use the filemanager in the rom - browse to backup folder and install astro file manager.
than use astro file manager and install all the other application that you back up
than setup google account and your contact will be downloaded automatically from internet.
than restore sms using the kamma's backupsms.
its done. I spend about 30 minutes for this. This is my way of doing things. If you like you can follow this way.

How To: Backup or Restore via Nandroid
Nandroid allows you to create a complete system image of your device and stores it to the SD Card on your phone. Making one is very simple but there are a few prerequisites.
1. A rooted Android phone
2. A custom recovery that supports Nandroid (ie: Amon_RA, ClockworkMod, Etc.)
3. A MicroSD card that has enough space for a system image.
A complete image can range from 75-400 MB.
Please follow this link for instructions: http://forum.xda-developers.com/wiki...r_via_Nandroid
Ok, I got your point. You want to preserve you current ROM in the way it is now in case that you would like to go back to it.
In this case before restoration you have to follow the same steps like in installation of a new ROM:
Wipe all (system, data, cache)
Restore
Thanks a lot!

If you just want to simply restore one of your previously taken Nandoird backups then there is no need to wipe anything in advance as the restore will overwrite all partitions.
While saying that every time that I've performed a restore for safety's sake I always then wipe cache and dalvik cache before booting the restored ROM.

[Q] Nandroid data recovery

I have a Samsung Galaxy S Showcase, which is rooted, that I am trying to regain some data from that was stored in stock apps prior to attempting to install a new ROM. When I went to install the ROM I did the factory Reset and the data was lost. I have a MyBackup Root and a Nandroid backup. I tried doing a restore in the MyBackup Root app and it restored all of the apps except from the stock apps that came with the phone. Can anyone give any suggestions about how to recover the data? Thanks in advance for any assistance.
maybe this will help???
The easiest way to perform, restore or manage nandroid backups is to use ROM Manager. It is a free Android app that you download from the Android Market and use while running Android to schedule operations to be performed in recovery. It provides you with a GUI for installing ROMs as well as performing, restoring and managing backups. It does not perform the actions themselves but rather reboots the device into recovery after you have scheduled these actions, and then automatically performs them via recovery. For further information, check out our coverage of Android ROM Manager. Its interface makes using it a breeze as all the options are laid out very conveniently.

if you didn't backup that data seperately (like MyBackup or Titanium backup), you should get it from the nandroid backup i guess. its a bit more elaborate but shouldn't take too much time:
1] boot into recovery
2] make a nandroid/rom backup of the current state
3] restore your old nandroid/rom backup
4] boot into the old rom
5] backup the settings/apps/data you need from that rom with mybackup/titanium
6] boot into recovery
7] restore your new rom you just backupped in step #2
8] boot into your current rom
9] restore the settings/apps/data with mybackup/titanium.
Update
I tried to do an advanced restore on just the data partition via clockworkmod recovery, but it gets just so far into it and seems to lock up. Then I have to reboot into recovery.

[Q] CWM Nandroid restore AFTER factory reset. UPDATE!!!

I looked, but could not find an answer to this specific question.
Forgive me if it's been discussed before.
Here's the order in which i performed new ZEUS (build 6) install.
1) Titanium backup user apps.
2) manual backup of media.
3) Odin back to stock froyo.
4) Factory Reset.
5) super one click root
6) modded recovery install using cwm from market
7) re-install packages x2
8) install Zeus
9) Titanium re-install user apps.
10) ICS for v6 theme installed
Question: Can i move an OLD nandroid backup into the "_/clockworkmod/backup" folder and restore as if it i had not factory reset and re rooted?
Thanks in advance.

RE-EDIT!!
Sorry if all that was unclear.. it was drunk thirty when i sent that.
i went back to stock, then did a factory reset from within froyo:
Settings -> privacy -> Factory data reset.
i copied the nandroid backup to the comp before this, then copied it back to same folder once i rooted and installed zeus and made initial new nandroid backup.
My question is can I restore from a backup that the phone erased and i put back after re-installing CWM.

cwm backup file can be restored in cwm. I don't know if it can be restored by any other means.
You dont have to be rooted. You just need to have a working cwm...I have only worked with Red CWM.
If you are looking to restore a nandroid, I recm booting into cwm. wipe clean: factory reset, wipe cache, advance -wipe dalvik. mount: format system, data and cache. Then restore your nandroid.
That's cool. I'm gonna try it, cause I can throw it under a bus for a new one if it bricks.
My question was backtowherw I started...with a a new file structure... can I restore from an old backupfrom a different file structure.
I was and am rooted fro both backups.
I did and now have red cwm.
I do and will take notes.

this is not a normal nandroid / cwm restore.
If you're reading this : Please... let me know if this has been discussed and link me ...
or tell me what it you don't understand about my question or how it differs from the MANY cwm restores I've Don from nandroid backup.
I guess no one knows ; That's cool.
The problem is that I forgot to backup all my apps. That's the only reason I wanted restore to a nandroid backup that was deleted by froyo factory data reset.
Now I backup using titanium but apparently lost or deleted the tiba folder after I copied it to the hdd.
At any rate, I only care that I get all apps with data back.
So... is there another way?
Apk extract from nandroid using comp or android?
Sent from my perfectly working phone which I choose not to **** up by restoring from a backup I didn't really want anyway.
Not sure if this helps. But I always copy my nandroid back ups to my computer and my sdcard. That way if I ever need to restore, I can just copy the nandroid back up to the clockwork/backup folder.
Just reread, there are a couple of apps that will let you extract apps from a nandroid backup. I for get which ones though.

Thanks for this thread. I've been trying to find a clear answer to my question and this is about as close as I've been able to find. So, just to verify (I am a noob, after all):
In order to install a rooted ROM when you have already installed an unrooted 2.3.6 (in my case, the UCLB3 leak), you need to do a nandroid backup, then go back to Froyo stock, root the Infuse, install CWM, then follow the instructions on the box?
In my case, I'm interested in Dman's rooted etc. UCLB3. His instructions start with "Boot into CWM" and I suppose this is the only way to do so!
This is what you are saying you did more or less, right?

[Tutorial] Back-Up & Restore from a Android Device - Unrooted & Rooted Methods

[Tutorial] Back-Up & Restore from a Android Device - Unrooted & Rooted Methods
How to backup & restore all your
data, contacts etc..... on your
Android device running a Non-
Rooted STOCK ROM
*******************************
************
MyBackup
MyBackup works as a perfect
backup & restore utility for Non-
Rooted (as well as ROOTED)
devices running the Android
OS......
The app can be downloaded from
Play Store here : https://
play.google.com/store/apps/
details?id=com.rerware.android.
MyBackup&feature=search_result
(FREE VERSION)
Once installed open the
application and tap the Backup
button, an option will pop up
asking wether you want to backup
your apps or data.....
When you backup your apps via
MyBackup, you will be presented
with an option of either selecting
certain apps you want backed up
or all your apps......
With backing up your DATA you
backup either straght to your
SDCard or to a Online server, for
later restoring..... same with the
app menu you can choose what to
backup or backup the your entire
data on the ROM, when backup is
complete it will create a ZIP file
on you SDCard.......
You can also have a backup
scheduled for a certain time ,
which is a great feature to have
especially if you forget to backup
sometimes.........
To Restore you can simply tap on
the RESTORE button and restore
what you want........
*******************************
************
Manual Drag and Drop
Drag & dropping files from your
Android device whilst connected
to the PC is a easy & fuss free way
of backing up data, contacts,
images and other SD Card data.....
Take a few minutes of your time
to save yourself the heartache if
something unfortunate happens to
your Android device.
******************************
How to backup & restore all your
data, contacts etc..... on your
Android device running a Custom
ROM with Custom Recovery MENU
or Backup Software
Nandroid backup
For ROOTED Users, you will
obviously have a Custom Recovery
installed with your ROM..... As
with most Nandroid recovery
systems you can backup & restore
all data right from this menu.......
There are many custom recoveries
available the most common one
being the ClockworkMod Recovery, Just boot into
the recovery console, tap on the
backup/restore tag, usually
through the menu Backup and
restore > Backup or restore...
To Restore follow the same
method as backup option, boot
into Recovery Mode and select
Backup and restore > Restore.
*******************************
************
Titanium Backup
Another option for rooted Android
users is Titanium Backup.
Titanium Backup gives you direct
access to your system. If you have
not used this program before
make sure to read all release notes
and methods of using the program
as mistakes can be made....
Once you’ve launched the app,
click on the Backup/Restore tab
and click the Menu button on your
phone. From the menu that
appears, select Batch. At the next
menu, click [RUN] Backup all user
apps + system data. You can
choose to backup just your user
apps and system data but you can
choose a complete and total
backup of your phone.
Depending on how much of your
phone you’ve chosen to back up,
the initial backing up process can
take anywhere from a few minutes
to half an hour or even more. Just
like a Nandroid backup, you can
opt to copy the backup file to your
computer. Navigate to the /
Titanium Backup directory on your
device’s SD card and you can find
your backup there, ready for
safekeeping.
When you’d like to restore your
backup, you can enjoy the same
Batch function. Select Menu >
Batch. On the Backup/Restore
menu, scroll down to find restore
options.

Nandroid backup for stock rooted U11

Hello everyone,
it's a long time I don't do this and I wanted to make sure I do the correct steps.
I would like to try a custom ROM but I want to make sure I can go back to my rooted custom ROM if I want to.
Can you remind me what are the correct steps to do for a nandroid backup so that I can restore the previous ROM please?
I see many guides here, but still unsure if I do it right.
I use TWRP recovery.
Trying to reply by myself, hopefully someone will confirm eventually.
Reboot to TWRP recovery and select micro SD as save location.
Select the following for the backup:
- System image
- Boot
- Data
Chose the name for the backup and swipe right to backup.
The backup will be stored at TWRP -> Backups -> Serial Number -> Backup Folder
Is that correct?
This way I should be able to go back to stock anytime after flashing any ROM I want.
Yes, but you need delete pins, unlock password, fingerprints and etc before backup!
