Taking a big leap backwards to 25R

After playing with the latest update One+ One update 38R, I have decided to go back to old update 25R.  This is to see if battery life is really that great.  38R so far has came in around 24 hours for battery life, whereas in 22R I managed to clock over 30 hours.

Downgrading the lazy way or dirty flashing I thought should be a straight forward fastboot flash.  It was except that I forgot to put in required files in the right places causing an error.  The phone was permanently stuck on boot and I could not get into fastboot mode.

Did I just killed the phone?

 

No.  Fastboot mode is activated by pressing volume up and power.  Reverse from Samsung.  Flashed again and the phone boots up normally.

If anyone is interested, I used this modified script.
