Custom 21.290.23.00.00 firmware and 17.100.19.01.00 web interface for E5372
The firmware is based on the original global firmware version 21.290.23.00.00. It can be installed on any previous firmware (unless you have locked bootloader), or updated from a modified firmware.



Flash using balongflash (Windows, Linux).

Warning!
This firmware can render your device unbootable! Use it only if you are aware of all the risks and consequences. In case of any problems, do not wait for help, you're on your own. Do not install firmware by non-tech-savvy people request, and do not sell routers with this firmware preinstalled.

Changes:
  • Firmware digital signature verification in the firmware server is disabled
  • Added support for IPv6 on mobile networks (disabled by default, could be activated "ipv6" script)
  • ADB installed and Telnet activated (disabled by default, controlled from the OLED menu)
  • The stock versions of busybox, iptables and ip6tables programs are replaced with full-fledged ones
  • The "atc" utility is installed to send AT commands from the console
  • Installed "ttl" script for modifying (fixing) TTL (for IPv4) and HL (for IPv6)
  • Installed "imei" script to change IMEI
  • A local transparent proxy server "tpws" and a script "anticensorship" are installed to circumvent censorship to sites from the registry of prohibited sites in Russian Federation (IPv4 only)
  • Added DNS over TLS resolver stubby (version 1.5.1, compiled with OpenSSL 1.0.2p) and DNS-level adblock (IPv4 only)
  • Added extended menu on OLED screen https://github.com/ValdikSS/huawei_oled_hijack
  • AT^DATALOCK code is disabled
  • Added kernel module TUN/TAP (for OpenVPN and other programs)
  • Added OpenVPN (version 2.4.6, compiled with OpenSSL 1.0.2p) and scripts for DNS redirection
  • Added curl (version 7.63.0, compiled with OpenSSL 1.0.2p)
  • Added EXT4 kernel module and swap support
  • Added script for installing Entware application repository
  • Added script "adblock_update", for updating the list of advertising domains
  • Multilingual web interface with GSM/UMTS/LTE band selection menu

Have you tried to reboot it with power button after flashing? I'm not sure if E5273T uses exactly the same hardware, can't guarantee that the firmware is compatible with that model.

You need to flash the firmware first, reboot into download mode, flash web interface after that, reboot again.

Thanks for that. I'll try it again one the site is back up. Not sure if I found the WebInterface in the file. Perhaps I've missed it.

For some reason this firmware does not expose /dev/ttyUSB0 device when connected to a router running Tomato and huawei ethernet driver. I flashed E5372_Update_21.290.17.00.1087/Update_WEBUI_17.100.05.01.1087 files (I can provide on request) and LTE (HiLink) mode started working fine, but I really miss the option for running without battery.
Is it possible to modify this firmware? Or fix lack of /dev/ttyUSB0?
