I have a ZBT WE1026 router with Huawei me909u-521 GSM modem. It's a same device as ZBT WE826, but with the little differences.
Fresh firmware, based on LEDE:
lede-ramips-mt7620-zbt-we826-16M-squashfs-sysupgrade.bin
diffconfig: http://tinyurl.com/jy6zb4q
Some info:

I wanted to build a new firmware, based on last stable release, but I couldn't do it.
This commands:
git clone https://git.openwrt.org/openwrt/openwrt.git
git clone https://git.openwrt.org/openwrt/openwrt.git -b v17.01.4
git clone https://github.com/lede-project/source.git
git clone https://github.com/lede-project/source.git -b v17.01.4
create same build - OpenWrt SNAPSHOT r6520
This build has many-many glitches for my hardware, and can not be used.
Where can I find stable LEDE source, last before OpenWrt/LEDE merge backward?
Now, I can not build 18.06...
18.06.2 image is too big even if drop most packages, placed in 17.01.
Privet !
I have both, the 1026 and the 826, with different configs: No samba, but nginx, php, squid, collectd, openvpn. And the 1026with a quectel modem, serial, too.
At first glance, you might
Poka !
Privet! 
To drop opkg - is a good idea, thanks!
And, by this way, I found this: https://openwrt.org/docs/guide-user/additional-software/saving_space
So, I builded 18.06.2 image with good set of packets, but LEDE 17.01.6 image include excellent set!
I don't know what to choose.
17.01 is about to be EOLed with v19 imminent, so I'd suggest 18.06
18.06, as you should also get newer wifi-drivers (MT76)
Gde Tbi shiviosh ?
Device incompatible 
Is target we1026-5g-16m really for ZBT WE1026?
Or I mast use we826-16M target?
В Москве. 
btw, traditionally "ты" == "ty"
In my .config:
CONFIG_TARGET_ramips_mt7620_DEVICE_we1026-5g-16m=y
However, I did this build about 3 weeks ago (from TRUNK), so something might have changed in the meantime.
Actually, I can not build again, as I am travelling.

I found that we1026-5g-16m image create successfully with size more then 16MB (16.3 I have), but we826-16M - not. I think it's a mistake.
Therefore, I cannot load such image.
О! А я наоборот - не люблю Питер.
18.06.2 has big power consumption - about 2x - by comparison with 17.
LuCI-nginx not work in both.
ssh not work without Dropbear, with OpenSSH.
sshfs not work with Dropbear, without OpenSSH 
Rake everywhere...
I have a ZBT-WE1026 device:
I think the profile for we1026 has problems.
Which sources did you use ? 18.0.6.1, 18.0.6.2, or very last TRUNK ?
Difference in my working 1026 is the modem only, which is a Quectel EC25. Cheaper than the Huawei, which I also have in other devices, but out-of-production.
However, obviously you have some specialities, like sshfs, LuCI-nginx which might be the real issue. Although I am also running nginx on my 1026. When you say, only the 826-image works for you, then you might try to do a "diff 1026/.config 826/.config" . As these ones should be almost identical.
OR just do a standard image generation for the 1026, without any special/private customization. And check, whether this one works.
I trying LEDE 17.01.6 and OpenWRT 18.06.2.
I do:
Build workable LEDE 17.01.6 image with target zbt-we826-16M and with applications. With ssh, sftp, LuCI via lan and wi-fi.
Create diffconfig.
Copy LEDE 17.01.6 diffconfig to OpenWRT 18.06.2 as .config
make defconfig
make
As result, I have (semi) workable OpenWRT 18.06.2 image. It work, but need some tuning and have more power consumption.
After, I change target to we1026-5g-16m, and
make clean
make
both on LEDE 17.01.6 and OpenWRT 18.06.2
Result no have lan and wi-fi. May be - it works, but how?
Sorry, mea culpa: I just noticed, that there are two different variants of the WE1026:
WE1026 and WE1026-5G. Difference is 5GHz WiFi, and lack of WAN-port on the WE1026-5G.
As I wrote, I have the WE1026-5G, so for you this image might not work.
But the image of the WE826 works, incl. modem, correct ?
Yes, except soft-contrilled LEDs.
And yes, my WE1026 has WAN port and no has 5Ghz WiFi.
Hi, could You share working version? I have the same model (with WAN, without 5G) and looking for as newest as possible working version.
Thanks in advance

Was my firmware useful to you?
Privet ! Actually I am interested to buy a https://zbtwifi.com/productinfo/1073325.html (plus LTE modem) which in fact is a WE1026-16M in an outdoor enclosure. Can you still confirm, that the WE826-16 image works on your WE1026-16M (besides LEDs) ? If yes, which is the openwrt version, you are using ?
