You can install any kitkat bootloader..minimum is MJ5 or a newer...you cant downgrade i think to lower BL...i found somewhere kitkat BL list with download links here on xda...but cant remember in which thread...Is there one that you recommend over another? It looks like some aren't downgrade-able. I looked at Dr. Kenan's tools but they took me to spam sites. It also looks like MJ9 is out now. Any that I should absolutely avoid or should I just just go for MJ9?
