Question [Q] Menu Back buttons Capacitive light not working after update

Need help urgently. My phone updated from 4.1 to 4.4.2 and buttons stopped working. Everything is stuck. It was stock update. Tried even custom rom DN3 but still the same. My note 2 is from UAE.

I have tried all the method, even custom rom. Now warranty is void so cant even go to samsung service center. Cant downgrade also. i read about samsung service center downgrading to 4.1 on this forum. need help.

Very strange. I went to samsung repair center and they had to replace motherboard. then camera was not working and headphone was giving issue so that was replaced. Seems all the hardware is replaced and phone firmware is at 4.3. did samsung rollback the update.

Finally back on track. lets see what next. knox back to 0
