Revise it return fy 2016-17

Better to file revised return & e-verify.......

Yes, but system has not 'invalidated' it till the time, so a chance to pressurize  the pending issue...

Firstly thanks both of you for valuable feedback & expert opinion

I revised the return successfully. But he don't have his mobile number linked with aadhar. If  I sent both ITR V copy in same envolope ( Fy 2017-18 & Fy 2016-17) It will work?

Yes  ..... Definately......

& thanks for practically verifying of the fact again...

In the meantime (i.e. 120 days/ manual processing of ITR V) better solve the mobile linking issue & e-verify as soon as the option re-starts.. it will be more safe.
