[Solved] WE-1326 firmware from ZBT

I emailed ZBT's sales group, and asked them if they had the later firmware then what it ships with at 14.07. He sent me:

mt7621-openwrt-512m-20171208.bin

I'm still waiting for the router to arrive, but I was wondering if anyone knew which version firmware he may have sent me? Also, are there any folks that actually have this device that could shed some light on it's all around performance with LEDE? Is wireless stable? I had issues with wireless on my WDR4300 (TPlink) using LEDE, and ended up downgrading back to the last build of OpenWRT to stabilize wireless. Any input would be appreciated!

So I received the WE-1326 last night. I have so far left OpenWRT 14.07 on the router. To be able to update/install packages I had to change opkg.conf settings to:

dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay

I was able to get extroot working w/ a 32GB micro sd card as well. Partitioned off 100MB for packages, 128MB swap partition, and the remaining 31GB as ext4.

Does anyone know if there is a way to put this router into recovery mode without erasing everything? When I held the reset button it forced me to upload firmware again, and erased everything. On my TPlink TL-4300 I can hit the reset button about 3-times quickly, and the router goes into recovery mode where I can ssh into it, and recover backup firmware via cli.
