The last few log entries are "aboot.nbm", "", "Complete(Write) operation failed.", "All threads completed (succeed 0/ failed 1)" Now I get a yellow triangle when trying to boot the phone. How can I return back to stock?
That's what happens when sites post directions that don't get updated. You would have been OK if you had noticed that the directions they're providing are almost a year old, and ONLY work if you happen to have a phone with a MDK bootloader. At the time, that's all there was.
To return to stock, first figure out what firmware version you have, then get the ODIN kit for that release.
My Android devices:
vzw Samsung Galaxy S4 stock NC5 rooted
Samsung Galaxy Tab 2 10.1, also stock but rooted.
VZ Droid Incredible 2 rooted but otherwise stock.
