please check whether WAVECAR was read successfully: this is only done if all calculation parameters match (k-point set, basis set, number of bands), ISTART is set properly, and WAVECAR is provided to be read. In all other cases, an electronic scf calculation is done

these are all same, only i cahnge ICHARG from 0 to 2 in this case. What i have seen is if i keep ICHARG unchanged, then it is all well.

please set ICHARG=11 or 12, (depending on whether you continue from a converged CHGCAR file or from super-imposed atomic charges), indicating that a non-sc step is to be done. Otherwise, the charge will be updated (by doing a full sc-electronic step), even if WAVECAR has been read successfully
