Reactivation Lock-out Solution (Re:"Custom binary blocked by reactivation lock")
I turned on reactivation lock, not realizing the repercussions. Upon rebooting my phone the first time after turning it on, I got the message saying "Custom binary blocked by reactivation lock". And I could not get past that initial screen. You should still have access to Download mode, which I did (Vol down + Home + Power).
So using Odin (v3.09), I flashed the newest firmware for my carrier using "AP" to select the file, and default Odin settings. (Specifically the tar file in the main .zip file: N900W8VLUBMJ4_N900W8OYABMJ4_N900W8VLUBMJ4_HOME.tar .md5) Again, it might be carrier specific, so only try flashing the one specific to your phone.
Everything booted up fine for me. :victory:
I immediately went into Security settings and de-selected Reactivation Lock option.
I then used Odin to reflash TWRP recovery.
I've since went back to flashing custom ROMs, with no problems.
I hope this helps. :good:
