Hi , I have embedded devices where the Cinterion PLS8-E modem is used - My earlier batch of devices are working but my new batch of devices are having modem issues - If I replace the modem from an earlier batch to the new batch it works - So issue is with the modem - My findings on the difference between the two modems is the firmware version (I don't think this is the issue), I checked all the parameter settings and the 2 modems are the same . The new modem is connecting to the network and I can talk to it from my application but my application does recognize that there is pppo connection. What I have found tht the USB3 setting on the new modem is different from the old modem via the AT^SSRVSET? - Old and New listed below

I am looking for urgent help , firstly on how do I rollback a firmware on the new modem and how can I get the AT^SSRVSET? setting to bee the same .
