Hi,

Hope someone can help me. I'm having problems rooting my Note 4 N910F. Initially I tried CF's autoroot but my phone went into a loop with the message "CF Auto Root, Set Warranty bit : recovery" message appearing in the top left. I could not get it out of this, so then tried to install TWRP recovery. This seemed to be successful as the phone rebooted and i was able to use my phone again. See Odin log :

<ID:0/004> RES OK !!
<ID:0/004> Removed!!
<ID:0/004> Completed..
<OSM> All threads completed. (succeed 1 / failed 0)

However when I tried to get into TWRP it simply boots into the stock android recovery. When i try to do a OTA update now I get the message " The operating system on your device has been modified...."

Thanks
