[Q] Help please noob(ish) issues
Hi first of all thanks for reading, I need help, I have rooted my phone using Philz and then went onto flash a rom. First one I tried had no app store so reflashed over it, that one was unstable so now I'm on paranoid android 3.99 which I'm finding OK. The issue is I never made a backup when I put my first rom on of the original Samsung rom so now can't find how to put the original firmware on(I thought I had but turned out I did it wrong) I must say I did all this rooting and rom installing via sd and not odin. Am I right in thinking that all rom files are zip and you only have to unzip them to use odin? So the questions are..
1.do I have to change the kernel for each rom or do some come with a kernel in its file? ( assume some do as where it says kernel on my phone it no longer says philz)
2.can I recover the stock firmware and install via sd and not odin?
3.a back up in Cwm in suitable incase anything goes wrong?
Any help or shoves in the right direction will be highly appreciated
Thanks in advance
