I have the ATT I337 s4 with 4.4.2 firmware and am trying to install liquidsmooth V3.2 but obviously its not working. I keep getting an error that states:
"E: signature could not be verified"
"E: whole package signature could not be verified"
And then the phone factory resets itself and reboots.
What I have done: Rooted the phone with towelroot, then installed supersu, disabled knox, and then installed busybox.
Some posts I read said that i need to use safestrap to install liquidsmooth, so i tried that as well, and it says the installation is successful, but the program state never changes to show "installed" and the button to reboot into recovery never gets activated.
I am not sure what I am doing wrong, but I think from what I have read that I need a custom boot loader in order to get the install to work, such as CWM, but then i run into other posts that say:
"NOTE – For AT&T/Verizon users with Android 4.3/4.4.2 or higher, you cannot use the LOKI method, you need to use SafeStrap Recovery to install custom ROMs, see How to Install Custom ROMs on AT&T/Verizon Galaxy S4 using SafeStrap instead!"
Im hoping someone can fill in the gaps that I am missing because it is getting annoying having my phone factory reset after every attempt and having to start over again, but its better than a brick lol.
Let me know what you think, and please help get me in the right direction
