I bought in aliexpress ZBT WE1026 router with Huawei me909u-521 GSM modem. It's a same device as ZBT WE826, but with the little differences.
Unfortunately, seller not set right firmware to it.
I create my own firmware by this steps:
1) Apply this patch to the buildroot: https://dev.openwrt.org/ticket/19996
patch -u -p1 < openwrt-zbt-we826-support-v3.patch
Partially manually.
2)./scripts/feeds update -a
./scripts/feeds install -a
3) make menuconfig
Select:
Target System (Ralink RT288x/RT3xxx) ---> │ │
│ │ Subtarget (MT7620 based boards) ---> │ │
│ │ Target Profile (ZBT WE-826) --->
4) make defconfig
6) make menuconfig
for add:
kmod-usb-net
kmod-usb-net-qmi-wwan
uqmi
usb-modeswitch
kmod-usb-serial-option
kmod-usb-serial
kmod-usb-serial-wwan
- for GSM modem
kmod-usb-storage
kmod-usb-storage-extras
fdisk
file systems...
e2fsprogs, etc...
codepages...
- for usb storage mount
kmod-mms-spi
mms-utils
kmod-spi-gpio
kmod-sdhci-mt7620
- for SD card support
ntfs-3g - for ntfs file system support
LuCI
7) make
After this, you will have a functioning firmware, without LEDs support. I don't know how configure LEDs.
All of this menuconfig's are: http://tinyurl.com/jy6zb4q
Rename diffconfig to .config and run make defconfig
diffconfig include a mc, picocom, polipo, sshfs, etc.

I welcome corrections my work.
