Which firmware is installed? M919UVUAMDL

What version of wireless tether are you using? latest from Google Play

What steps will reproduce the problem?
1. start wifi tether

What is the expected output? What do you see instead? started with errors, 
can't open log-File, does not exists

Please provide any additional information below.

I have tried 3 different versions, the one from google play and a couple from 
trevE but I can't get the tethering to start, I am rooted via the one click 
root and it asks me to grant root permissions and i do, i have other programs 
running that require root and they function OK, (lucky patcher, adfree, etc etc)
i have uninstalled, rebooted and reinstalled multiple times with the same 
result.
any help is highly appreciated

Me too. I used 3.4 experimental, 40, and another earlier version. I have tried 
many settings. The fact is it is not creating any error logs for me to post. 
All gave problems as unable to open log file. File does not exist.
