Looks like reverse engeneering on kernel is SO diffucult and I wonder wy haier (or acer) doesn't release the source code.
Anyhow, I'm on elbuit v5.5 , run fine, even i MUST use link2sd, I have a lot of apps...
And its looks like any 4.1 rom can do wifi tethering.
No matter what settinsg or encryption, 3rd party tethering tools makes phone reboot!!!
I'll try the bluetooth one..
Battery increased a lot on elbuit to.
Actually, I love this phone, but with no edited kernel we can use only a little of his power!
