The vendor firmware checks for a bmt header in the last 528 erase blocks
of flash. The OpenWrt partition table did not respect that requirement,
and therefore the vendor and openwrt chainloader fight over those blocks
on every boot, potentially corrupting data stored in UBI blocks there.
This commit increases the size of the reserved_bmt partition to avoid
that fight.
Although the vendor bootloader only seems to touch the final 250 erase
blocks[1], the original vendor firmware system partition ended at
0x1be00000[2], so to be conservative, the consensus is to use that as
the end of mtd2 (ubi) partition and leave the last 528 blocks for mtd3
(reserved_bmt).
From https://openwrt.org/toh/gemtek/mxf-w1700k:
[1] OEM bootlog: [ 5.324337] bmt pool size: 250
[2] OEM bootlog: [ 5.478927] 0x000008600000-0x00001be00000 : "system"
For the backport to OpenWrt 25.12, the device support has not yet been
committed, so revising the compat_version in this commit is not needed;
and instead will be handled by revising the pending device support
commit.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.
Sunshine!
Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
