Cloning a phone with a Nandroid backup requires a separate step to copy over the data from the Internal data partition. It is not included in the backup. The normal process is to physically transfer the ExtSDcard with the backup on it, so all the other data on the card also gets moved.
After "imaging" a phone with TWRP backup (and other tools), and restoring onto a new phone this way, most data is retained.
However so far I have found a few things that are not.
1) Wi-Fi passwords have to be re-entered. (maybe they are stored in a way that hashes the Wi-Fi MAC address??)
2) All Bluetooth devices have to be re-paired (unavoidable since the MAC address of every phone is unique, and part of the pairing)
3) If used, Systemless root has to be re-established by flashing SuperSU from recovery.
4) Any DHCP reservations have to be updated with the new Wi-Fi MAC address.
Has anyone discovered any other data that is not preserved or transferred through the process of Nandroid backup / restore, and copying Internal and ExtSDcard data?

When you backup via nandroid (on Amon), what do you select?
I just left it on defaults but haven't had to do a restore yet so wondering.
From memory I think the following options are UNticked by default
- recovery - I assume this is Amon_RA itself, and I would never need this unless I totally screw it and have to manually push the nandroid backup from adb including the recovery image?
- sd ext - I assume its just the rest of the SD card = doesn't matter?
- .androidsecure - I assume its apps2sd, since I use titanium for that = doesn't matter?
Any experts advice appreciated, cheers
1. You don't need to check 'recovery'.
2. If you're using any custom ROM that can move your installed applications to Ext partition, it should be checked for backup. Otherwise, you may have problem when restoring it.
3. .android_secure is where the application goes when you move it to SD card. I recommend it to be checked if you moved any one to SD card, to reduce the chance to be screwed when you restore your backup.
Thanks I'll try again
Folks
I did a full backup of system, data, etc on TWRP (2.66gb total folder size) - can I assume that should I corrupt my phone somehow, I can restore from this and the phone will be in the exact state when I did the backup - all apps, logins, etc intact?
Also, I do weekly backups with titanium free edition - does titanium does the same thing or should I still do the above every few months?
Thanks

It's a complete "snapshot" of your phone as it was when you took it.
No titianium does not do the same thing. Titanium backs up individual apps and their respective data so you can restore individual apps or all apps at once. It's benefit is when switching roms where you have to wipe the phone and you can just restore your user apps without restoring any system data
I use the app ultimate backup to back up apps and data and I use the TWRP backups just as a safety measure before flashing a new ROM or update.......
I like to start a fresh you see with a new ROM, and then just install ultimate backup again, move over the back up data that I previously copied to my PC, and restore them, and this basically returns everything to how it was before due to the launcher, Nova, and its settings also being restored.
I had a big problem with the backup of my moto x 2014, i lost photos, videos and download of the internal memory of my phone! :crying:
I made a Nandroid with TWRP 3.0 Recovery by selecting all the internal partitions of the phone as: a system, date, boot, efs, cache .. So all the internal partitions and made up of external usb otg pendrive (since the moto x has no sd external)
Everything went well and after he finished the backup to external USB OTG I did a wipe advanced as I had backup !!
The problem is that when I restored all were gone all my photos and personal file are lost !
If he did not do a Nandroid A COPY MIRROR OF ALL MEMORY? Why it has not included in the DATA partition, even my files?
I did not know did not backup personal files!
Now what interests me is: There are software type PhotoRec to recover even low-level files from the internal memory of the phone because in theory are still there? and they have not been overwritten ...
If they were an external memory there was no problem photorec enough, but in the internal memory of the phone that use software?
Please I need suggestions! Thank you.

Twrp does backup your data if you select it.
Photorec won't work. If you don't have a backup they are gone forever.

"Twrp does backup your data if you select it."
..Are you really sure ?
Because I have selected all of the flags from Backup in TWRP 3.0 , included DATE, but when I restored the Nandroid when I go in the Downloads folder or camera or other folders these are empty !! nothing files! why ?
There is a way to "scan" low-level partition of the internal memory of the phone as it happens on hdd computers ?
Some recovery software might work for you.. Root access is necessary for that, usb cable, adb enable.. Thats it! Google it don't remmeber the name android recovery or idk.. Last tried year ago one note 3 kitkat.
Somehow the EFS partition on my P5WIFI got damaged and everything was lost. Is it possible someone has a dump of the files stored in there? The loss of the data in this partition causes strange problems with the stock Android.....
I managed to recreate some amount of the EFS partition by using "EFS Professional". The Wifi MAC is incorrect (looks like a generic one) but hey whatever.

You have got a Wifi Tab , and Wifi Tab does nt have got a EFS Partion.
I think you need a PIT file.
Normaly if you flash a Stock Rom this will restore a EFS Partion in Phones.
On the WiFi tablets, the EFS partition stores unique data like your WiFi MAC address.
I'm not sure what happened to this tablet. It was my mother's until last week. Somehow it wiped itself. All of her data was gone. It seems as if something caused the tablet to wipe the data partition, and that the EFS partition was also damaged. The EFS partition was not mountable in recovery and errors were displayed. Nothing actually formats EFS though, including PIT, so I had to go in with ADB shell and format it myself.
But without the EFS data, strange things happen like the stock ROM will go into factory mode. It puts a "factory mode" icon on the homescreen, the lockscreen and power menus don't work, and the initial setup wizard is never shown. Fortunately "EFS Professional" has a function that recreates various files within the EFS partition and this restores normal functionality.
Rooting Note 8 SM-N950F without wiping data
Is it possible?
And if not possible, how to I restore from backup after the root? Cause I want to keep all my data after the root.
Someone told me that if I restore from backup after the root process, the data will be encrypted, what does that mean? That I will not be able to read or write anything I restored?
Thanks for whomever answers :good:
I thought it was using the easy root method (no TWRP) but when I rebooted it had wiped the entire device.
Not possible by the looks of it.

Unfortunately the samfail process is going to replace the system and when flashing the files will require a full wipe to complete it.
This is just the 1st time to get onto rooted cfw. Once there you can use safestrap twrp and make full backups or you can use flashfire.
Otherwise use smartswitch app and backup data to sd then restore that way, the pc smart switch route is broken once rooted.
What if I would backup with Samsung cloud? Or Google drive?
You have Exynos so SamFail is not for your phone. You would be rooting after installing TWRP. Unfortunately TWRP will require you to remove encryption initially which requires formatting the data partition.
What data did you want to backup? Like app data?
Internal storage won't get wiped but if you don't format to remove encryption after installing TWRP you will no longer be able to access it when trying to boot to system. Internal storage is easy to backup, just copy to dekstop or external storage.
To back up app data without root, I believe these days there are a few options now. Check out Helium. I don't have any experience with it but I hear that's a good one for app data backup without root. After you do root & get settled, Titanium Back Up has always worked great for me.
