Hello, I would like to request the latest firmware for the RM520NGLAA-M20-SGASA. I had gotten firmware before (RM520NGLAAR01A08M4G_01.206.01.206) and it worked in MBIM. However, I wish to switch to QMI, and for some reason the firmware I have gets stuck when I try to switch USB composition to 0x51. I was using AI to help me get the modem switched so I have no clue if that is what I am supposed to do but whenever I try the command: echo -e “AT+QCFG=\“usbcfg\”,0x51\r” > /dev/ttyUSB2 it would turn out error on both USB2 and USB3. Which lead to the AI suggesting that the firmware I was given is very old, and that is why it has two AT ports when it is not supposed to and is MBIM-locked because of the firmware.
Ok I think I got it working in QMI. Will still take a firmware update if it is actually super out of date. My router which is a Bananapie R4 Pro is about 200 Mps slower than my Cudy P5 which should not be the case since spec wise the R4 should be vastly superior. Likely a Openwrt firmware problem and not the RM520NGL but I have no clue so far.

Ok, will give it a try this weekend. Thanks for the help.
Sorry, took me long to try it out. It worked and it seems to have fixed my network problems. Used to only get 1-5 upload and now get the 10-20 upload I should be getting with T-Mobile. Seems my modem with the wrong firmware was not attaching to the T-mobile network fully so it was causing slower speeds.
