How to Use

To run the Toolkit:

Open ADB & Fastboot++ covered in Using ADB or just use adb
Make sure your modem is connected by USB to your computer
Run adb devices to make sure your modem is detected by adb
Run adb shell ping 8.8.8.8 to make sure the shell can access the internet. If you get an error, make sure the modem is connected to a cellular network and make sure AT+QMAPWAC=1 as covered in the troubleshooting section: I Can't get internet access from the Ethernet port (Common)
If you don't get an error you should be getting replies back endlessly, press CTRL-C to stop it.
Simply Copy/Paste this into your Command Prompt/Shell

adb root
adb shell

Then run

cd /tmp && wget -O rcPCIe_SDXPINN_toolkit.sh https://raw.githubusercontent.com/iamromulan/quectel-rgmii-toolkit/SDXPINN/rcPCIe_SDXPINN_toolkit.sh && chmod +x rcPCIe_SDXPINN_toolkit.sh && ./rcPCIe_SDXPINN_toolkit.sh && cd /

Useful AT Commands

You can send more than one command at once by sperating them with ; and not including the AT part. AT+QENG="servingcell";+QCAINFO for example to see the info from both AT+QENG="servingcell" and AT+QCAINFO

PCIe RC Ethernet mode setup

For use with a board like the Rework.Network PoE 2.5gig RJ45 sled

For x70 modems (RM550/551)

For BETA versions of firmware: the adb value 2 trick still works so one and done:

AT+QCFG="pcie/mode",1;+QCFG="usbnet",1;+QCFG="usbcfg",0x2C7C,0x0122,1,1,1,1,1,2,0;+CFUN=1,1

OR if you are running the latest non-beta firmware

AT+QCFG="pcie/mode",1;+QCFG="usbnet",1

Then unlock ADB:

Ask the modem for its adb code by sending: AT+QADBKEY?

It'll respond with something like +QADBKEY: 29229988

Take that number and paste it in this generator: https://onecompiler.com/python/3znepjcsq (hint: where it says STDIN)

You should get something like

AT+QADBKEY="mrX4zOPwdSIEjfM"

Send that command to the modem and adb will be able to be turned on with the next command

Now you can turn it on with the usbcfg command AT+QCFG="usbcfg"

Be super careful, this controls what ports are on/off over USB.

Run it and you will get the current settings. Something like this:

+QCFG: "usbcfg",0x2C7C,0x0122,1,1,1,1,1,0,0

Send AT+QCFG="usbcfg",0x2C7C,0x0122,1,1,1,1,1,1,0 to enable adb

Now you can reboot: AT+CFUN=1,1

This will do the following:

Enable PCIe RC mode (Driver selection is automatic now)
Set to ECM mode via USB and AP mode connection behavior
Force Enables ADB Access
Reboots after all the above

Tip: APN automatic selection will somtimes choose the wrong APN. You may need to set your APN after powering up with the SIM inserted.

The List

AT+CFUN=1,1 (reboot)
AT+CFUN=0;CFUN=1 (Disconnect then reconnect)(tip: run this after chnaging APN and you don't have to reboot)
AT+QMAPWAC? (get current status of auto connect, 0=disabled 1=enabled)
AT+QMAPWAC=1 (enable auto connect internet for ethernet)
AT+QMAPWAC=0 (disable auto connect for ethernet; use when you want internet over USB to work; IPPT must be disabled)
AT+QUIMSLOT? (get active sim slot; 1=Slot 1; 2=Slot 2)
- AT+QUIMSLOT=1 (switch to sim slot 1)
- AT+QUIMSLOT=2 (switch to sim slot 2)
AT+CGDCONT? (Get active APN profle st 1 through 8)
AT+QMBNCFG="AutoSel",0;+QMBNCFG="Deactivate" (Disable Automatic APN selection)(You will need to set your APN when you switch SIMs or Slots)(Can also set APN after you switch the run AT+CFUN=0;CFUN=1
- AT+CGDCONT=1,"IPV4V6","APNHERE" (Sets APN profile 1 to APNHERE using both IPV4 and IPV6)
AT+GSN (Show current IMEI)
AT+EGMR=0,7 (Show current IMEI)
AT+EGMR=1,7,"IMEIGOESHERE" (sets/repairs IMEI)

AT+QNWPREFCFG="mode_pref" (Check what the current network search mode is set to)
AT+QNWPREFCFG="mode_pref",AUTO (Set network search mode to automatic)
AT+QNWPREFCFG="mode_pref",NR5G:LTE (Set network search mode to 5GNR and 4GLTE only)
AT+QNWPREFCFG="mode_pref",NR5G (Set network search mode to 5GNR only)
AT+QNWPREFCFG="mode_pref",LTE (Set network search mode to 4GLTE only)
AT+QNWPREFCFG="nr5g_disable_mode" (Check to see if SA or NSA NR5G is disabled)
AT+QNWPREFCFG="nr5g_disable_mode",0 (Enable Both SA and NSA 5GNR)
AT+QNWPREFCFG="nr5g_disable_mode",1 (Disable SA 5GNR only)
AT+QNWPREFCFG="nr5g_disable_mode",2 (Disable NSA 5GNR only)
AT+QNWPREFCFG="nr5g_band" (Get current SA 5GNR bandlock settings)
AT+QNWPREFCFG="nsa_nr5g_band" (Get current NSA 5GNR bandlock settings)
AT+QNWPREFCFG="nr5g_band",1:2:3:4:5:6 (Example: Lock to SA 5G/NR bands n1,n2,n3,n4,n5, and n6)
AT+QNWPREFCFG="nsa_nr5g_band",1:2:3:4:5:6 (Example: Lock to SA 5G/NR bands n1,n2,n3,n4,n5, and n6)

AT+QMAP="MPDN_rule",0 (turn off IPPT/clear MPDN rule 0; Remember to run AT+QMAPWAC=1 and reboot after)
