That's possible to some extent, but the reception would be very poor due to hardware difference in different models. Not worth it.

Bro can you add 1800, 2100 frequency 4g for us in Indonesia for the next update? thanks btw for your contribution.
yea must be calculate earcfn for optimizing

on Huawei Honor X1 7D-503L you can unlock FDD- LTE band with write NV
at^nvwr=53802,4,00 00 CC 01
53802 is address for LTE band
nvwr is command for write NV

but in indonesia for LTE band use TDD not FDD
2100 mhz is B1
1800 mhz is B3
TDD 2300 mhz is B40

---------- Post added at 09:28 AM ---------- Previous post was at 09:13 AM ----------

B1=01 (in hex)
B3=04
B40=80 0000 0000
so when you add b1+b3+b40 = 80 0000 0005

thats is teory EARCFN = LTE bands, if GSM use ARFCN

Hello, using this firmware it's possible to switch to modem mode only (over USB)? Thanks!

Edit: seems that using this firmware my router is able to use the E5372 connection!
I've another question: there is no 5 GHz option on the webui, I'm also unable to disable the WiFi of the device (considering I'm using it as usb modem).

Hi, were you able to switch to USB Modem without NAT at all? I can see the device on my router, but only as a router itself which would mean double NAT, and wondering if it's possible to use it as if it was just a modem

    Okay, but after the extraction process is complete. I open the Huawei web ("192.168.1.1") displaying the SIMLOCKED message, as in the picture. how to handle it

    Https://ibb.co/BwDzWM1
    If your device is SIM locked, you need to unlock it manually. The easiest is to execute:
    Code:
    atc 'AT^NVWR=8268,12,1,0,0,0,2,0,0,0,A,0,0,0'
    via telnet.

    Previously with the FW Stock the modem was correctly recognized by my fritzbox 7390 as a backup lte unit.

    Now, on the other hand, it is recognized as a USB disk and I do not have the possibility to navigate via the modem with the fritz Box.
    Your FritzBox can't switch modem to another composition (usb_modeswitch is missing or not configured properly). It could be that your previous firmware has special settings which allowed it to be used with FritzBox.

    Try choosing "AT, Network" under "USB Mode" in advanced OLED menu. It should help.
