thanks for this link
but in step two which version should i flash using sd card for recovery?
and this guide is for ICS not JB
It worked the 2nd step but in 3rd step to fix boot and storage error his file is ICS not for JB should i run its .bat of ICS for my xt912??
or how can i solve boot and storage error?
Activate "USB Debugging" and plug to pc, find the root folder from "Xoa CID & Root.rar" archive and extract,
then run "EasyRootICS_Windows.bat"
cellphone will reboot 3 time, remember to boot in "BP Tools" always
when done, run EasyRootICS_Apps.bat to install apps
in Cellphon Run Boot Menu Manager, install Hjihack, in 1st system turn on the first 2 items,
now restart, and after 3 seconds the cellphone will pass costumer id error and boot properly.
