Troubleshooting Firmware Update Issues on E220 900T22D and 900T20D with EByte Software

I Renzo, I have some problems to update orginal configuration parameters of my E220 900T20D and E220 900T22D. I am using RF_Setting(E22-E9X(SL)) V3.2 for configuration however I can only to read the parameters and I can't save new configurations because the software tool send me some errors, such as the images than I share. I recently bought some new E220 900T22D modules, I configured them at 915 Mhz, but in practice they cannot communicate with other devices that I already have working. In fact, when I want to check the parameters again, they have already been changed. Has something similar happened to you? Right now what occurs to me is to try to get the original firmware to restore the modules because I cannot update them with the tool provided by the supplier.
