Actually maybe I am wrong if 32.4.A.1.54 has already been patched the dirtycow exploit. Not sure about that now.
Maybe need to downgrade firmware for backup TA as well.
I may still have a 32.2.A.0.305 firmware somewhere, if you need it.
Hhhhmmmm... When browsing into the forum, I read about this information if I'm not wrong, can't remember where I read it.
I'd rather do the right thing. Don't wan tto brick my phone heh
