[Samsung Galaxy S9  Questions & Answers] machine134:
Hi all,

Some quick background: A few days ago while I was using my S9 plugged in, my device all of a sudden froze. I did a force restart (Volume Down + Power) and from then on my phone would boot up, get to the white 'Samsung' logo then shut down and restart over and over. It never could get past the 'Samsung' logo. I tried a bunch of the solutions in Recovery Mode that I could find on the internet (wipe cache, etc.) and nothing worked so I ended up as a final resort going with the factory reset option. The same issue persisted after factory reset which lead me to this forum and giving Odin a try.

I found the correct firmware for my phone from this site which matched the firmware my device showed in recovery mode. I initially bought the phone through Rogers but switched to Bell and had them unlock it. I followed the instructions from this forum trying both the Bell and Rogers firmware's which gave me a FAIL! My phone read SECURE CHECK FAIL: system. I reset tried using Home CSC and CSC for both firmware's and neither worked. Then I downloaded the patched Odin3 v3.13.1 from here with both firmware's (after reading you may have to use it to patch unlocked phones) and got the same error. I then tried 3.14.1 and the patched version from the same forum, both giving me the exact same error. I then tried running all of the Odin programs as administrator, still the same issue. I also tried various different USB cords and ports, nothing has worked.

My phone is now stuck in Download Mode with an Error message reading 'An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.' but Odin still seems to be working with it so I don't think that is an issue. I tried the Smart Switch software which did not even pickup my phone like the instructions.

Below is my 'Log' from an attempt with the Bell firmware on Odin3 v3.14.1. I have gotten the same error across all Odin versions and with both firmware's. Under the 'Options' tab in Odin, Auto Reboot and F. Reset Time are selected by default. I tried deselecting one then both, as well as selecting 'Re-Partrition' and still no success

Sorry for the long post. Any solutions or help that can be offered would be greatly appreciated. I am new to this so is there something I am doing wrong? Please let me know if you need anymore information

SUMMARY: Phone would not stop rebooting over and over, never making it past the 'Samsung' Logo. Tried everything I could in Recovery Mode including a factory reset. Issue persisted. Tried to flash the firmware via Odin3 v3.13.1, 3.13.1 patched, 3.14.1, 3.14.1 patched, all failed in the same spot (FAIL! Auth SECURE CHECK FAIL: system). Firmware matched what my device showed in Recovery mode. Tried 2 different carriers, one that I am currently using and one that I bought my phone through. Stuck and need help.
