Unhappy RX TX confusion in Micromax A106


Hello brothers/sisters,

Phone : Micromax A106 Unite 2
Problem : Preloader is corrupt, so the phone is not detected in PC.

I wanted to flash ROM using the serial UART cable and SP Flash Tools. The TX point works good but there are two RX points RX0 and RX1 and none of them works.

The voltage at both RX0 and RX1 is 1.7 V.

I know TX is working, because it is sending log every few seconds.

Please tell me which of these points is going to be used as RX?
