[Samsung Galaxy S7 Questions and Answers] elfion:
I am very sorry if this is a dumb question, I have been having sex with this phone for a few days and I have no idea what I am doing. and my wife is going to kill me if I don't get her phone and data up and running soon :crying: so I was trying to recover some files that got acidentally removed from the device and I decided to root it. I thought, it's not going to be a big deal... and so I didn't backup. (facepalm)

So I used instruction on gadgethacks dot com (can't post a link because I am new here), however I ignored the part where they say you need to validate that your phone is compatible. (again, facepalm)

I flashed AP = CF-Auto-Root-herolte-heroltexx-smg930f.tar.md5 using Odin3-v3.10.6.exe and now when the phone restarts I get "Verification failed Unable to restart your device. The integrity verification has failed. You need to reset your device to factory default settings. This will erase your data."

Then I discovered that in download mode it says that my phone is SW-G930W8

Then I found this file and I tried to flash it.

CF-Auto-Root-heroltebmc-heroltebmc-smg930w8.tar.md5

same error message.

Then I flashed twrp-3.2.3-0-herolte.img.tar

I can get into the twrp recovery, but still can't boot the system. then I used adb in twrp mode but can't see any of my wife's files in internal memory, I am guessing because they are on an encrypted partition or something like that. but I can access /system/ and so I found a file called build.prop where it says that my Android version is G930W8VLS3BRC2

so I found this amazing site called firmware.mobi where I was able to get a recovery from that specific version of android... and still the same error message comes up.

So I was following the instructions of the root manual so I have developer mode turned on and "OEM unlock" enabled if that helps at all.

Please help me :( Any advice is very much appreciated.

Question 1: Is it possible to save the data in the internal memory of the phone? i.e. either boot the system or fetch and decrypt the partition? How?

Question 2: If not, then how do I at least get the phone to work again? Just do what it says and wipe it? Or flash some complete stock ROM?
