According to the Chart your CECH-4211a is a PS3 Slim 4K meaning you won't be able to downgrade it with a flasher... your only choice may be to look into an ODE (Optical Drive Emulator) hardware mod.

Up to now it's primarily useful to developers or those who have a newer PS3 Reference Tool that want to run less restricted lower Firmware on it, for example if Sony added new protection or blocked certain 'useful' commands that are still present in previous revisions.

For those who are curious, and if joonie can find use from this I have a early model of the reference tool at my shop. Its primarly silver in color runs even older firmware however I cannot update it past a certain point its firmware is different.
