I put the G530T in download mode and I tried with G531F and G920K as Nyonyo mentioned in this thread. Both models gave me errors but to my surprise I put the phone in download mode and I see FRP Lock is set to OFF.
The phone got bricked after doing all this showing a yellow triangle. All I did, flash the whole firmware and the phone is back in business.
Taking a risk pays off sometimes.
