Kox Free Root 66 is always preferred over Stock update. The instructions and all the necessary files are in the Root66 Thread.
In short you need Odin v 3.xx Need to have the Drivers installed for your phone. Make sure Kies is not installed on your PC. Put your phone in Download mode and then connect to pc. Flash the Root66 file and you are done. There are several tutorials on Youtube for how to use Odin.
Note - For your Knowledge, please read on the 4.3 and its locked bootloader.
Hey just wondering if I should do the update to stock 4.3 OTA or not. I've been looking at the root66 knox free 4.3 and it sounds good. Any Issues with it? or stock OTA? I've read mixed reviews, and am now confused. Also if I do install root66 on this wind t999v, am I required to install the stock OTA 4.3 update for it to work? Or am I in a better situation if I just install it from 4.1.2? Also any basic instructions on what I would have to do to install root66 would be much appriciated. I'm technologically inclined, just been out of the cellphone moding scene for quite some time, and just want to ask before I start asking how to unbrick. Thanks in advance.
