If you recently picked up a UZ801, UFI001B / UFI001C, UFI003, or HMUF02-V05 4G LTE USB dongle and searched for uz801 openwrt, openstick openwrt, or msm8916 postmarketos, you might be wondering which operating system you should flash onto your stick.
While three different open-source projects target Qualcomm Snapdragon 410 (MSM8916) 4G modems—OpenStick (Debian GNU/Linux), OpenWrt, and postmarketOS—they differ dramatically in installation safety, software compatibility, and daily usability.

Embedded router BusyBox (musl) |
Alpine Linux (musl + OpenRC) |
| 1-Click Automated Installer | ✅ Yes (openstick-installer for Win/Mac/Linux) |
❌ No (Manual fastboot / edl CLI) |
❌ No (Requires pmbootstrap on Linux) |
| Automatic IMEI / QCN Backup | ✅ Automatic 1:1 eMMC backup & calibration injection | ❌ Manual backup required (easy to lose 4G IMEI) | ❌ Manual backup required |
| 4G LTE Cellular & Wi-Fi Hotspot | ✅ Built-in (ModemManager + NetworkManager) |
⚠️ Often requires manual QMI / NCM packages | ✅ Supported via ModemManager |
USB Ethernet Gadget (RNDIS) |
✅ Plug-and-play USB network card | ⚠️ Requires custom USB gadget kmods | ✅ Supported |
Standard Linux Packages (apt) |
✅ 60,000+ standard ARM64 Debian .deb packages |
❌ Limited router opkg packages |
⚠️ Alpine apk (musl breaks proprietary binaries) |
| Docker & Containers | ✅ Native support (especially on 1GB UFI003) | ❌ Not designed for Docker workloads | ⚠️ Requires extra cgroup/OpenRC tuning |
| Best Use Case | 4G Travel Router + Pocket Debian Server + SMS Bot | Pure basic routing only | Mobile/phone UI experimentation |
Many makers initially search for uz801 openwrt or openstick openwrt because they want to replace the insecure factory Android firmware with a clean 4G LTE Wi-Fi travel router or USB cellular tether.
However, OpenStick (Debian) gives you every routing feature you want from OpenWrt—plus a full 64-bit Debian server:
1. Zero-Risk 1-Click Flashing & IMEI Protection
Community OpenWrt and postmarketOS images require manual edl.py and fastboot commands. One wrong partition erase wipes modemst1/modemst2/fsg, permanently killing 4G LTE reception. The 1-Click OpenStick Installer automatically clones your full eMMC and injects your factory IMEI calibration into Debian in under 0.1 seconds.
2. Instant 4G Wi-Fi Router & USB Gateway
OpenStick Debian comes pre-configured with ModemManager (mmcli) and NetworkManager (nmcli). With a single command, your stick routes 4G LTE to both its onboard 2.4 GHz Wi-Fi Access Point and your PC over USB Ethernet—no fighting missing OpenWrt kernel modules (kmod-usb-net-qmi-wwan).
3. Full Debian `apt` Ecosystem (glibc)
Unlike OpenWrt’s stripped-down filesystem or postmarketOS’s musl C library, OpenStick runs genuine Debian ARM64 (aarch64). Every Raspberry Pi, Ubuntu, or Debian tutorial works out of the box—including Python, Node.js, Tailscale, WireGuard, Pi-hole, and Docker.
4. Stock 'OpenWrt' Seller Listings Are Often Fake
Beware of AliExpress listings advertising “OpenWrt 4G Dongle”. Most actually ship locked-down Android 4.4 or non-Qualcomm ASR1802 / ZX297520 chips with a fake web skin. Always check our Verified Buying Guide for true MSM8916 eMMC hardware.
Once you flash OpenStick Debian using the 1-Click Installer, you can configure a 4G LTE cellular WAN connection and broadcast a Wi-Fi hotspot using standard nmcli commands:
# 1. SSH into your OpenStick dongle over USBssh user@192.168.5.1
# 2. Enable the 4G LTE modem and connect to your carrier APNsudo mmcli -m 0 --enablesudo nmcli connection add type gsm ifname cdc-wdm0 con-name "4G-WAN" apn "internet"sudo nmcli connection up "4G-WAN"
# 3. Create a Wi-Fi Access Point (Travel Router Hotspot) with NAT sharingsudo nmcli device wifi hotspot ifname wlan0 ssid "OpenStick-4G" password "MySecurePassword123"NetworkManager automatically handles DHCP (dnsmasq), IPv4 packet forwarding, and nftables/iptables NAT masquerading between the 4G LTE modem (wwan0), the Wi-Fi hotspot (wlan0), and the USB Ethernet interface!
Want a web dashboard like OpenWrt’s LuCI? Because you’re running full Debian, you can install Cockpit (sudo apt install cockpit), RaspAP, Pi-hole, or AdGuard Home directly via apt.
