Installed 4.1.2 ROM over Android 4.3 rooted stock ROM.
I had some problems with tethering two weeks ago. I usually don't really care about upgrade but because of connectivity issue. I went ahead and updated my SGH-T999 to Android v4.3.
I was on Android 4.1.2 rooted. In any case, tethering is now inoperable. VPN connection speedtest is horrendous. I have it rooted using root66 method. I have been using TrevE Mod Wifi Tether App before but it's now longer working. I also tried purchase "Wifi Tether Router" and it was useless.
My Warranty Bit is now 1 but I don't really care about the warranty. I owned the phone almost 2 years now and didn't buy any insurance so insurance is irrelevant.
What I really really need help on is either to be able to tether again or revert it back to 4.1.2. From reading some of the threads, it said that once you go to 4.3 you can't Odin any previous releases. But it seemed you can flash previous release ROM.
Here are the some questions:
1. Is there any way that I can fix tethering with 4.3? With or without VPN connection.
2. Is there any way, I can flash 4.1.2 ROM on to my phone and would this allow me to tether again?
Thank you for all your help!!!
