EC25-E Adding MBN files error

Can you check this issue related to adding mbn files?

The model & frimware is Quectel EC25 - EC25EFAR08A02M4G (Version) info from QNavigator.

I tried to add a specific MBN from Pixel 3 firmware but it didn’t work. Can you please read the QCOM LOG and tell me why?

Have you managed to activate own MBN on the module? I experience the same. No error is reported on ‘AT+QMBNCFG=“Add”,“RAM:mcfg_sw.mbn”’. Are MBNs digitally signed and it’s not allowed to load MBNs from other devices to Quectel modules?

Did you solved the issues?? We still haven’t managed to add additional mbns.
