You cannot use EasyRootTool for the newest ROM's - you might be able to use How To Root the newest firmware (.314)
Btw. .39 is for the Chinese Z2?

Well I rooted my Z2. 314 firmware last night and it worked. I used ERT V11. It took 2 attempts mind you, cause I wasn't watching what I was doing the 1st time lol ?
Sent from my D6503 using xda premium from "Somewhere, but not here..."

Thanks, is this tool unlocked the bootloader? I don't want to unlocked the bootloader.
.39 is Chinese Z2 LTE version's last fireware.
Z2 in China has three version, 3G/TD-LTE/LTE
