Upgrading Quectel EC-20 to support Euopean LTE bands

IoT Modules LTE Standard Module

@leon.bao Hello again. Sorry to bother you.
I have an EC-20 LTE module module that has the following markings: EC20AA-256-STD / EC20AQAR02A03E2G / A QA
Could you please verify that this is a North America version of the card?
I am located in Europe, I got this card on eBay from the US as part of a package deal, and I can get no signal with this modem, when trying to use my provider.
Could you tell me whether it is possible to perhaps flash this modem with the EC20‑E (Europe) firmware in order for it to support my European LTE bands (namely B1, B3 and B20)?
If it is possible, would you please send me the latest EC20‑E firmware? Is the upgrade procedure the same as with the upgrade we did earlier?

Thanks in advance!
János

Hi,@Janos_Szigetvari

Sorry, the EC20A and EC20E are different modules. Firmware cannot be cross-flashed between them, as this may brick the module.

Thanks for answering my question!
Too bad, but it is what it is.
