OTA update Fail, Save my data



Hi ~

- Be kind with me, it's my first post! -

I'm facing a very bad problem with my Galaxy S6. A week ago I received an OTA from Samsung and I installed it. My phone rebooted and showed the bugdroid, meaning that the update was progressing. After that, the device keep rebooting over and over just after I entered my encryption password. I said to myself that I can try to wipe the cache because maybe an application was causing this problem. But now, the device is only showing the Samsung logo then just shut himself off.

Now I need your help to get my data. The hard part is that my device is encrypted. After many hour of search I see two solutions:
  • Flash the rom via ODIN

  • Install TWRP which can read encrypted volumes


The first solution seems easy and I keep the warranty. The problem is that I'm not 100% sure that flashing the rom again will not touch the /data and /sdext partitions (and the header/footer where master key are to decrypt the volume).
The second solution seems safer and should not touch any other partitions. But knox counter will be incremented and I will loose my warranty.

So, does anyone could test if flashing the rom via ODIN do not absolutely touch encrypted volumes and certificate that I will be able to get my data again?

Thank you a lot
