installation update firmware in s7 edge rooted - Samsung Galaxy S7 Edge Questions and Answers

Hi, since I have the s7 edge cell with root and twrp recovery, I would not want to lose all the installed apps.
If I reflash the firmware and then reinstallerei the TWRP recovery and root for your phone, then I should do a wipe data / factory reset to restart the phone. So I would lose everything as happened to me in the past.
Is there a workaround so as not to lose everything? Thanks in advance.

You can backup all app be settings with titanium backup and restore free flashing your rom

Restore backup problem

Hi,
yesterday I decided to install new ROM - Cyanogenmod 12.1 on my Galaxy S4 only for tests. Before that I done backup with every partitions:
boot
system
data
cache
EFS
I'm using TWRP 2.8.7.0 recovery
After tests I restored my backuped ROM, but unfortunately OS doesn't work, I cannot even put my PIN code. Every time I see pop-ups with apps stoped working.
What I am doing wrong or how can I restore properly my old OS.
You may have to perform a factory wipe after restoring your old ROM or you may need to flash stock recovery to perform a factory wipe.

Can't restore stock rom backup from TWRP (SM-G900F)

Hello,
before I played around with getting root and flashing custom roms, I backup everything in Samsung Smart Switch.
After getting root and install TWRP, I backup the whole system (except the recovery partition) to the external sd-card from TWRP.
Now - after getting some experience with custom roms - I will go back to the stock rom from my TWRP-Backup. Set everything to factory default, wipe cache and dalvik and press restore. Select my backup... swipe to flash... everything seems ok. After reboot - no bootloop - a thousands of alert-messages pops up "blabla-app stopped"... Then appears only a black screen.
How can i restore my backup from TWRP? Or is there a stock-rom, so i can backup from smart switch? My System is a LRX21T.G900FXXU1BOJ1
Thanks alot!
Try clearing the caches from recovery and boot again
If it fails, try wiping everything again, then restore all partitions except DATA
See if it boots
If it boots - either reinstall apps etc manually, or use TiBu to restore the DATA partition
I've got it!
I flashed a stock rom with odin and restore with smart switch. Some settings are missing, but i think 90% is restored
Nice job

SM-G900F with TWRP 2.7.1.0 - Nandroid restore resulting in all apps force stopping

Hi experts,
I would very much appreciate some help regarding the following:
I have a Samsung Galaxy S5 SM-G900F with factory installed stock rom G900FXXU1BPA2 (Android 5.0). I used the SkipSoft Unified Android Toolkit 1.4.5 to root the phone and install TWRP recovery (2.7.1.0-klte as recommended by Unified Android Toolkit). I made a first Nandroid Backup and was able to successfully restore this backup (I restored boot, system and data to verify that Nandroid restore works). I then used Titanium Backup to restore my apps from another phone, and all was well.
A week or so later I wanted to modify something I wasn't sure I wanted to keep (using apktool). I therefore made a second Nandroid backup and then proceeded to make modifications to the phone. After I saw the result, I didn't like it, and therefore restored the second Nandroid backup. After rebooting, the phone gave a flurry of forced stops ("Unfortunately XXX has stopped"). It is not a bootloop but I can't do anything meaningful with the phone other than restart it.
To try and resolve this, I used TWRP to wipe cache and dalvik cache and rebooted. The phone went through the lengthy "Android is upgrading" process but the result was the same: all my apps force stop.
I then decided to try and restore the original first Nandroid backup (which I had been able to restore successfully earlier), and this resulted in the same issue. Since I have several backups of this first backup I was able to verify that the files were good. Also did MD5 checksum verification in TWRP and it all checked out.
Using Odin, I was able to restore a stock ROM from SamMobile (G900FXXU1BOL1_G900FOJK1BOL1_ILO) and after restart, the phone works as usual, but of course all my apps and data were gone.
I was then able to use TWRP to restore only boot and system from the second backup, so I would be back on the exact same ROM that my phone came with, and this worked just fine; the phone started as if factory restored.
I then used TWRP to restore only data, and this resulted again in the same problem: all apps force close. Note that this is a restore of data only to the same phone running the exact same ROM that the Nandroid backup was made on, and it still did not work.
I have been thinking about this issue and searching through the various forums but I did not find anyone having this same exact issue. Here are some questions I came up with:
1. Is TWRP 2.7.1.0 completely compatible with this phone and with Android 5.0? Would it help if I installed a newer version of TWRP? Would I be able to restore Nandroid backups made with TWRP 2.7.1.0 with TWRP 3.X?
2. Assuming my second Nandroid backup is not corrupt, is there a better (less intrusive) restore I can do of the apps? Can Titanium Backup read TWRP 2.7.1.0 backups and restore them, including SMS?
3. What could be the reason for TWRP 2.7.1.0 restore not to be working properly? I did activate the fingerprint reader after the first Nandroid Backup, but if that is the issue I would have expected that first backup (in which fingerprints were not yet enabled) to restore properly and it doesn't.
Would appreciate any help!
Thanks,
AH
That version of TWRP is pretty old, possible it doesn't fully support 5.0
Grab 3.0.0.0 from here (newer versions are not fully bug free yet)
https://dl.twrp.me/klte/
Flash .tar version with ODIN 3.10.7
TiBu can read Nandroid backups and restore apps yes
Not sure about SMS
The method you used to root and flash TWRP is not a usual method used here, most of us use ODIN to flash TWRP and then flash SuperSU from recovery
or use CF Auto Root to root, and then flash TWRP with ODIN
I'd flash stock again, factory reset, and then flash TWRP and SuperSU, then try restoring your apps with TiBu

Thanks *Detection*! I installed TWRP 3.0.0.0 as per your instructions and restored just data. Same result as before.
Then I used TWRP 3.0.0.0 to restore the entire backup including system, boot, recovery, and data. Same result (of course I lost TWRP 3.0.0.0 and was back on TWRP 2.7.1.0).
This exercise was useful for one reason: I now know that TWRP 3.0.0.0 is able to read Nandroid backups from TWRP 2.7.1.0.
This is quite crazy but I seem to be unable to restore a full Nandroid backup and get a working system.
Am going to try Titanium Backup.
Thanks again!

Backup existing Data after fresh install of TWRP before ROOT

Hello,
I have an S7Edge and looking to flash it. I am currently in Nougat 7.0 and would like to backup my data before proceeding with the root.
I have flashed the phone with TWRP but when following this tutorial: https://forum.xda-developers.com/s7...overy-official-twrp-hero2lte-3-0-0-0-t3334084
People say that you have to format the Data Partition in order to proceed with the installation of SuperSu and NO Dm verity.
Is there a way to backup my phone data [w or w/o TWRP] before ROOTING my phone with TWRP (format data partition to decrypt, install no dm verity and install super su)? This is so after my phone is rooted, I can restore all the apps, pictures, etc.
Thank you for the help! :fingers-crossed:

Hi,
Thank your forwarding me to your thread. I think I figured out a way to fully back it up with the following steps:
1) If you are in Nougat, downgrade to 6.0.1
2) Root your phone by flashing CF-Auto-Root in Odin (it should not wipe any data)
3) Once phone is rooted, you can backup your phone with TitaniumBackup or Flashfire
4) Save the backup in your sd or other external
5) Update phone with official or custom Nougat FW
6) Root phone via custom recovery (TWRP), will have to format all your data
7) One phone fully booted up and rooted, restore from backup with TitaniumBackup or Flashfire
Let me know how it goes

S7 Edge root without wiping data

Hi,
Has anyone had any success in rooting S7 Edge without wiping data on it? I have seen many threads on TWRP recovery, CF-Autoroot but seemingly they will wipe the data while rooting. I accidentally deleted some of my important photos and need to recover them. But all the recovery software require that the phone be rooted.
Thanks in advance.
