Replaced both o2 sensors on 2003 Camry, but light comes back on. Any help? on 2003 Toyota Camry

Code called for upstream oxygen sensor. I have replaced both as the car has 135,000 miles.

What brand sensors did you use? Some aftermarket's just dont work! Possible citcuit problem as well.
The upstream sensor was an after market, and the downstream was a Bostch.
DENSO, NTK/NGK. Is what i have the best luck with on Toyota! No luck with Bosh on anything!
does the live data show catts are ok and what about o2 readings
