[Samsung Galaxy S7 Questions and Answers] crisse78:
Hello,

I have had problems after SuperSU update came to my Samsung Galaxy S7 (international version SM-G930F). My phone was rooted and everything worked fine. Then I got a notification that SuperSU needs to be updated. On my previous phones SuperSU updates have succeeded every time so I presumed updating works without a hassle also with S7.

I accepted to update SuperSU and after a while I got a notification that the update was succesful and I was suggested to reboot the phone so I accepted it and after that the problems started.

After reboot I got an error:"Device memory error: the data partition has been corrupted. You need to reset your device to factory defaults. This will erase all your data". I rebooted several times and also pressed Volume down + Home button + Power button (same as removing the battery as there is no possibility to remove the internal battery of S7) but those actions did not help, always same error after the phone started.

I had backups of my files so I made the factory reset as there was no other option on phone screen than "Reset" (after selecting Reset I had to select factory reset in recovery menu).

After that phone started normally but there has occured three problems:

1. When I want to move an application from phone internal storage to my microSDXC card I go to "Applications" -> "Application Manager" and select an application and go to Storage. After that below "Storage used" I select "Change" and select my external microSDXC card as a new storage location and I get an error:"Not enough storage space" although there is a lot of space in both microSDXC card and also internal memory (someone told this can also refer to internal storage). I have tried this with several applications but always the same error. I have not accepted to use Adaptive Storage (and I think that is disabled in S7).

Before SuperSU update+factory reset I was able to normallly move my applications from internal storage to the external storage (and also from external storage back to internal storage). Otherwise memory card works normally and my phone detects it.

2. When I connect my phone S7 to the computer (I have tested with several computers) and I have my microSDXC card in my phone, computer only shows internal storage of my phone, not my microSDCX card. I reformatted microSDXC card (tried both FAT32 and exFAT) but that did not help. I also tried with other memory card that worked fine with other phone (when the other phone is connected to the computer with USB cable both internal and external storage are seen) but same card in S7 did not show in Windows. Reinstalling Samsung S7 USB drivers doesn't help.

3. I cannot root my phone anymore, Odin detects my phone (shows added) but when selecting the required file to AP and clicking Start it goes to Failed status. I downloaded SuperSU and it tells my phone is not rooted.

Any suggestions what to do?
