i.e. Busy Box, Boot Linux, Terminal ES File Explorer while showed rooted were not having access.
Spent the whole night figuring how to accomplish as everytime I tried the Exploit I use to get the following error
[*] Phase three (this will take a minute)...
failed on '/data/logger' - Permission denied
mkdir failed for /data/logger, File exists
Unable to chmod /data/logger: Operation not permitted
link failed File exists
Thus, meanwhile I came across this Post which took me good 2 hours to decipher as per logic, plus few others and this is how I achieved a ROOT on my XT912 again without downgrading (and without having to have Voodooo Temp un-root and stuff)
1) Unmount the Ext-Sdcard I basically removed it
2) Make sure your Debugging option is enabled, USB Mode change it to MTP or Camera Just don't keep Mass Storage.
3) Settings> Apps > All > SmartActions
Once Above steps are done
Proceed towards the exploit, plug you Mobile, execute the Exploit
As soon as you see "[*] Rebooting device..." for the first time, and screen turns off, immediately press Vol Down + Vol up & Power Button
In it select the last option BP Only
Rest follow the process of Exploit as they come on screen.
(I personally waited 30secs after Selecting Save on Battery Saver option).
All due thanks to orignal coders who invented the exploit, took it further, XDA & Droidrzr Forum and also to [Link]http://www.droidrzr.com/index.php/topic/36187-ota-9872165-11014/#entry395166[/Link] which gave me the direction over a good nights sleep.
Hope it helps others also.
