Red triangle after upgrading to kitkat

[tranim]

hi

I recently upgraded my Samsung s4-9505 from jeally bean to kitkat but after upgrading I found many problems
1- whenever I try to boot in the recovery mode I get a red triangle and android lying in the ground
2- the battery die really fast
3- and sometimes a sudden restart.

please help me to solve this red triangle issue or just show me how to downgrade to jeally bean .

please help
thanking u in advance

I think there is an error in the recovery partition. You could try flashing a JB ROM with Odin.
