Possibility of upgrading PLS8-US Rel.2.1 module to Rel. 4 functionality. | Telit Cinterion IoT Developer Community

We've just completed a production run of tracker circuit boards but learned that our supplier provided PLS8-US Rel. 2.1 modules instead of Rel 4 devices.  It's going to be a lot of extra expense reworking boards to swap out modems.  We do have direct access to the ASC0 serial receive and transmit pins in our design. Can you please tell me, will a Rel. 4 firmware upgrade of the Rel. 2.1 modules solve the problem or are there hardware differences between these two versions of the module that make them incompatible?  If the upgrade will work, where can we find the Rel. 4 firmware, please?

Thank you,
