Click to expand...

Click to collapse

After youve unlocked it to root. So you still lose your data the first time you unlock it.

Which recovery image should be used for that? Standard recovery, CWM, TWRP?

You can't fastboot boot something without an unlocked bootloader

yep, I installed it too...
however one important thing you should not forget (copy/past from a review) :

"Works great but be careful Once you have unlocked and rooted your phone this app works great to lock the bootloader again. But use caution when updating OTA. I allowed an OTA update to Android 4.4.2 while locked and I lost root access (expected) but because I didn't unlock before the update, I am now locked without a way to unlock unless I wipe the phone. Great app. Just make sure you know what it does and how to use it."

--> unlock before to apply an OTA
