Hello Experts…
I have Samsung Galaxy S8+ (SM-G955F) and I have to recover deleted movie files and other data.
In order to recover i have to root this phone but unfortunately i can't find any useful link how to do it (even on xda developers site).

Is there any possible way to root that phone without losing existing data ? ?

Thanks for any replies.

You will not recover deleted photos/media even if you will root or get physical dump from this phone…..

Bolo thanks for reply .. but could you explain why not ?

Ive got several phones to examine. I rooted every single one of them which was necessary to recover data.

I've got samsung galaxy s6 edge Android 7.0 and there was no problem with rooting it and recover data.

The phone I'm talking about here - S8+ (SM-G955F) has also Android 7.0.

I know this is quite new phone (2017) but what is the problem ? Please could you tell me why I cant recover data from it, even if I somehow rooted it ?

Its very important to me..

Thanks..

Im talking about media as photos and videos… not databases/files. Reason phone is encrypted by default

P.S
Few words about rooting which are mainly used I don't like and don't use Rooting since is not a way of recover deleted data in my point of view. If you are working on phone where you need to recover deleted data rooting will/will not replace some of deleted information. Depends where overwritten file for getting SU will be stored in NAND… from physical point of view in block of memory and their logical block numbers connection there are no difference if rooting affect only system partition or data because it's still changes data in NAND cells……

Ok thanks .. so encrypted are only media? not databases/files ?

And about that encryption by default …this depends on android version or device model ?
For example in Galaxy S6 the media wasn't encrypted ?

You are surely right - rooting can overwrite some data .. but what method instead do you suggest to recover data?

one more thing … on galaxy s8+ isnt encryption only enable when the phone is locked py password ?

When i unlock the phone by typing the PIN I automatically decrypt the data, am i right ?

The phone i'm talking aboout isnt protected by any password. I have full access to that phone so it means it isnt encrypted ?

Thanks for any replies.

For rooting, try to find SM-G955F ENG ROOT file. Root without tripping knox, but no guarantee of success.

Example with Samsung Galaxy S7

No. Most modern phones are encrypted by default and they don't need any kind of password to be set. It was introduced with Android 6 and every phone that was released with 6 (released, not updated to) should be encrypted. S6 wasn't, S7 already is etc.

… I really dont understand this right now 😯 (

By encryption I mean that my phone has protected / unreadable data and I need to somehow decrypt it - by typing the password (pin, pattern, etc).

Typing the correct password should decrypt data.

In my situation when the phone isnt protected by any password… what does it mean it is encrypted by default ? Right now anybody could take the phone, boot it because it has no password ang get access to all data (photos, movies, sms, etc).

Yes, but data is still encrypted and if you make physical dump you'll only see encrypted userdata partition and your data will be unreadable. Same goes for data recovery for anything other, than logical analysis done directly on the device. Currently, if you enter setttings, then security and look for encrypt device option you should see that it's already encrypted. Setting a password will re-encrypt those data with your new password.

By default, the decryption key is stored in the hardware-backed storage using Trusted Execution Environment’s (TEE) signing capability (such as in a TrustZone). The data partition is decrypted with that key automatically once the device reboots. While this may sound lame (what’s the purpose of encryption anyway if the data can be decrypted without user interaction?), bear in mind that extracting the decryption key via chip-off or any other low-level method is not possible, so if you do a chip-off you won’t get the decryption key and won’t be able to decrypt the data.
