Hey guys,
i'm currently running on stock android 4.0.3 (kernel 2.6.39.4+) and i want to install a custom rom on my device. (http://forum.xda-developers.com/iconia-a500/general/epic-wip-omnirom-4-4-4-a500-a501-v18-t2872956)

then install a recovery (cwm 6.0.45, http://forum.xda-developers.com/showthread.php?t=2583710)
and then flash the rom via cwm (http://forum.xda-developers.com/showthread.php?t=2792022)

Choosing a Custom Rom (version)

Hi all,
I have a question about choosing a custom ROM. My phone was running android 4.4.2 before I started flashing custom roms with TWRP. I have flashed a custom rom based on 4.4.2 (CM11) and 5.1.1 (CM12.1). I saw a custom rom based on 4.3 that I was interested in trying. Am I able to flash the 4.3 rom (after a factory reset of course)?
Sorry if this is a newb question, but I really dont want to destroy my phone doing something stupid.
Thanks!

First custom ROM

Hello!
I have a GT-I9505 (jfltexx) with android 5.0.1 (stock rom) and I would like to flash my first custom ROM - specifically CM 11. Do I have to downgrade to KitKat first (via Odin?) or can I just root, install TWRP and flash it from Lollipop?
Thanks in advance for any help you are able to provide.

Only thing you need to do:
- Flash TWRP
- Flash the custom rom you want.
ps do not use outdated custom roms like CM 11. Always use the latest custom roms available. Thus CM 12.1.

Yes you can but only with the correct custom recovery. Keep trying with older version twrp v2.8.6_no_image or cwm recovery, if you are somehow not able to do it
I think first you should install lollipop and then kk
