[Q] Bootloop - Nexus 7 Q&A, Help & Troubleshooting

Before this I had a f2fs android 5.0 ROM.Today I tried to flash a 4.4.4 ROM((f2fs too,of course),updated to the latest recovery version,wiped everything I could(yes,I changed back to f2fs),but I got stuck in a bootloop.Tried with another ROM,same result.What should I do? Does it have something to do with the fact that I try to flash a kitkat rom after a lolipop one?

Do a full wipe after downgrade from recovery.

bootloop problem

seems that everytime I try to boot into lollipop on my s5 it gets stuck in a bootloop at boot animation but if I flash 4.4.4 I'm fine boots right up what the hell.... Any advice?
Are you flashing a 5.0 rom before using Odin to update to 5.0? Different bootloaders prevent just flashing back and forth. You need to Odin a 5.0 tar and reroot then flash a lollipop rom

If you have any marshmallow in twrp all you need to do is restore it after wiping dalvike system data and cache no need to flash with odin marshmallow will boot ok even with nougat bootloader and nougat baseband.
