Samsung Galaxy S5 SM-G900T - fix "Set Warranty Bit : recovery"

November 26th, 2016 Leave a comment Go to comments

After a failed firmware upgrade, our SM-G900T refused to boot.  Its screen read:

RECOVERY BOOTING...
RECOVERY IS NOT SEANDROID ENFORCING
Set Warranty Bit : recovery


Attempting to boot to download mode by pressing and holding Volume Down, Home, and Power caused the phone to reboot, but return to this screen.

The fix was to remove the battery, then press Volume Down, Home, and Power, and insert the battery while these three keys were pressed.  It took some effort to do all at the same time, but was possible.

The device then booted to download mode and we were able to use Odin to reinstall the stock firmware which we obtained from Samsung-Updates.com.
