samsung galaxy s8 + rooted (NRD90M.G955USQS2BQL1) USA carrier

Friends,

   I have successfully rooted my Samsung device s8+. 

here is details which I found in xda-developers forums

My method is a little different than the actual SamFAIL method so please to tell me it says this in their thread. I feel my procedure is the best method for the S8+ and this method may not work on the other models so please follow there own set of directions. This method allows you to obtain root by simply flashing a modified system.img using only odin. These images include all carrier files and will work on all carriers. These roms should be stable and you can probably just use these as your daily rom. You can choose from stock odex rom or deodexed rom

This Odin Images Contain AQI2 Eng Combo Firmware with AQI6 modems, NON_HLOS.bin, persist.img.ext4 and system.img.ext4. CSC files are included in the system.img along with all carrier files
