I install a stock 6.0.1 UK(BTU) ROM on a Samsung Galaxy S5 (SM-G900F).
Then I encrypt internal storage (all of it). I don't setup any unlock method.
At this point, the phone can boot by itself, there has to be a "default_password" for dm-crypt master key.
But usually when only the default password is used for encryption and user don't have to type it to boot, TWRP knows it and uses the default password to decrypt and mount the partition.
But I install TWRP and go in recovery and I can not mount /data (invalid argument). I can mount all other partitions.
My question is: is there any other tool to access the encrypted /data? Or if not, is this storage really safe without setting a password you need to enter at boot?
I know encryption without password is not secure on AOSP, but is the Samsung version secure? If so, how did they do it?
Thanks!
Hi,
ive just followed the flashable oreo TWRP thread in here to test out Oreo.
My device is S8 G950F
link -> https://forum.xda-developers.com/ga...1-10-flashable-oreo-twrp-dump-beta-2-t3703083
After that TWRP didnt recognized my data partition anymore...:crying::crying:
So i installed latest TWRP in Odin again (had 3.1.1 before 3.2.0.0 after) - didnt helped.
Ive done a full restore with odin after i downloaded the firmware via samfirm, this is the exact firmware number ive used:
G950FOXM1AQJ5_CL12401979_QB15459675_REV00_user_low_ship
Still no success
I also tried flashing supersu (2.82) and dm-verifity (v.6.0).
Any ideas?
Is it just the partition table in twrp that needs to be updated or some stupid thing i forgot?
Regards

when you use wipe
choose data and use repair or change file system option
after resize file system and voila !!

Ok yeah it'll format whole internal storage.
You need to change the partition type of /data to f2fs and then change it back to ext4. Then two recognize /data again

It's not format.
Go to wipe, advanced wipe, repair or change partitions ,select data, select change partition type, select f2fs slide to continue.
Then do the same with data and change back to ext4.

its not magic you have all option in twrp wipe
I have done this and it works but as soon as i reboot and go back to twrp it doesnt recongize /data am i doing something wrong
after so many tests I discovered that twrp can read and write data only if you flash last supersu beta, magisk and supersu official both doesn't work:
https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
Does the resize option or file system option wipe internal storage?

Sounds like your internal storage is encrypted and you see cryptic named folders that are empty. You can check the "decrypt data"

Could not mount /data and unable to find crypto footer
Failed to mount /data (invalid argument)
Unable to mount storage ...

After flashing twrp you need to flash magisk or a custom kernel so the twrp won't be restored to stock recovery. Seems like you missed some steps on the instructions to root your device.

If you format internal storage it's nothing shown for sure, that's the purpose of format. After that you can install lineageos along with gapps from USB otg for example.
For DECRYPT data you should not format unless you backed up all to your pc!

What do you mean by "and doesn't change ..." exactly? Are you not able to install lineageos 15.1? I don't get you what's not working right now.

At least i can see my sdcard folder right now ^^
Guys, I do the first steps with TWRP, but I see my SD Card empty when I go to install. I don't know what to do.
I have Samsung Galaxy TAB E (SM-T561) and twrp_2.8.7.0_sm-t561
I Don't know what to do... I am stuck.

Ok, I found the solution.
Format and change file system of the SD card inside the twrp, after that mount it in PC, restore the files, and it will be ok.

Do you unlock the bootloader?
I have the same problem, did you solved it?
Sloved!
If you don't slove this problem to this time i can help you. You need to install china firmware v255, or restore backup from twrp if you have one or you can download it on 4pda, to restore /data dir you need to only one thing: go to "wipe" menu in twrp, mark /data partition and click on "reformat/restore partition" then chose one of types ext2/ext4 or other, then swipe to confirm and next do this thing one more time but restore original type of dir (if you have ext4 do ext2 then ext4) and you wil restore /data partition
