@slh I have recovered this way and was able to re-update to 18.06.2, but snapshots are still not working.
Between the kernel changes to resolve the recent CVE and some issues being worked through relative to libjson-c, I'd wait a couple days on snapshots. This is one of the very, very few times that master has had "bootability" issues over the last couple years. Actually, I can't remember another time in the last couple years.

@jeff Is there an older snapshot that I could try somewhere? And is there anyone else affected by the recent snapshot, from the same family of products lets say?
If you have a build environment up and running, you could build from an earlier commit.
(It's OK to respond to multiple posts in a single post.)

@jeff see this topic please, apparently my router is one that needs to be ported to ath79 :
Now I have no idea how to do this!
What's your level of confidence reading C code (not necessarily writing it), availability of a serial connection to your device, and tolerance for testing things?
With luck "all" you'll have to do is adapt a DTS to describe the device to the kernel.
I'll look at it in a bit (in the middle of some testing and merging here) to take a guess as to how hard it might be, but here are a couple references. The first is the learning process the early adopters went through. The second describes some of the references I found helpful when learning about DTS files myself.
https://openwrt.org/docs/guide-developer/defining-firmware-partitions (Really about DTS, in general now)
https://openwrt.org/toh/zyxel/zyxel_nbg6716
The hardware is very similar to the TP-Link TL-WDR7500, but with a large NAND flash
The Hynix H27U2G8F2CTR-BC listed on that page is parallel NAND, and I don't know if there is any support for it yet on the ath79 platform. Having been working on serial NAND on that platform ("SPI NAND"), I know that there aren't any boards running on the ath79 NAND target on master quite yet.
Best guess is somewhere between "hard" (a lot of groundbreaking work, but platform drivers for parallel NAND and your chip available) and "very hard" (requiring submissions and acceptance to upstream Linux).
@jeff I am sorry for not taking action on this for awhile. Waiting was actually a good thing, 19.07.0-rc1 came out. Now I got the new kernel version and I am able to get proper speed (tested 400 Mbps in download, perfect for me). I have seen this version has some issues to be fixed. I also noticed a bunch of errors from the serial connections. I have yet to take a capture.
I noticed that snapshots are still not updated, even if 19.07 exists. Is there anything I can do to help? To be honest, I still need to catch up to understand your last post correctly. I got some school background in C programming but I feel rusty! I am willing to invest some time in this though to prevent good routers to end up in the trash. Thanks for all your time!
here is the capture for 19.07.0-rc1

ar71xx is dead and, as I recall, is “source only” on master.
Also, 19.07 is a branch from June, as I recall, and is over 1000 commits behind master.
There is a parallel NAND driver on ath79 you can look at. I don’t recall if your device has been enabled yet. That kind of work only happens on master.
Edit: Yes, ZyXEL NBG6716 is on ath79 on master

I found a few commits here :
https://git.openwrt.org/?p=openwrt%2Fopenwrt.git&a=search&h=refs%2Fheads%2Fmaster&st=commit&s=nbg6716
I was still looking in ar71xx instead of ath79, now I see nbg6716!! I'll give the new snapshots a try soon 
I am starting to worry about writing on NAND too much though, I've been over flashing this poor thing.
@jeff I tried updating to ath79, but I got the reboot problem again. Found this info on one of the commit :
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=99835e09992bb411519fda1f8d16a6d07df7f598
I also took a look inside my unit to see what kind of NAND chip I have. It is a H27U1G8F2B. So 128MB. For future reference, here are the specs :
http://natisbad.org/NAS/refs/Hynix_NAND_128Mo_H27U1G8F2BT.pdf
I tried to follow the update procedure in the commit but I was not successful. It says :
Attention: Kernel partition size has been enlarged to 4MB.
To switch, you must update to latest ar71xx-nand snapshort and flash the
sysupgrade-4M-Kernel.bin:zcat openwrt-ath79-nand-zyxel_nbg6716-squashfs-sysupgrade-4M-Kernel.bin | mtd -r -e ubi write - firmware; reboot -f
First, the ar71 snapshots have not been updated since june 7th, which is what started this whole thing. I still get in a reboot loop, which prevent me to go any further.
I also tried using the latest releases, and the release candidate. That lead me to the second problem, the zcat command in the commit does not work. I tried tweaking it, but without luck.
Here is a capture of /proc/mtd for 19.07.0-rc1 :
root@OpenWrt:/# cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00010000 "u-boot"

and with the original firmware (after recovery using tftp) :

mtd10: 00200000 00020000 "bu1"
mtd11: 03c00000 00020000 "bu2"
my question is how do I write that -4M-Kernel file and on what mtd#? I tried kernel and ubi, without success.
Also in the commit, there is a place where he mention to go into uboot. Do I have to change something there?
Hi!
If you're stuck in the boot loop, try to flash the ath79 ras image via tftp to the device. This should help.
In some upgrades I had a problem with the ubi partition, it needed to be reset/cleared.
The ath79 version of NBG6716 only supports 128MB flash. With bigger chips the first 128MB will be used - should be enough. This is a difference to the ar71xx version where all was used.
Kind regards,
André

@avalentin It did it!!! In the past I tried with other bin files via tftp, but for some reasons it didn't work prior to flashing the original bin file from ZyXEL. So I was under the false impression that tftp only work for this one.
Btw, thanks a lot for porting this device!
I fixed the ras image generation with ath79 and NBG6716 
Have fun,
André

Off topic, so please feel free to start a thread on this to follow up.
While it may not be accepted into project code, it may be the case that setting the “last” partition size for 256 MB flash will just result in a “partition extends beyond flash” warning when the kernel initializes the MTD partitions on 128 MB device. I’ve seen that when I was off by a little (2 MB over) so might be worth exploring.
I have two of these and want to help testing too. Do I need to flash the original Zyxel firmware first and then the 4Mb image or can I use the full ath79 image directly?
What worked for me was flashing via tftp the openwrt-ath79-nand-zyxel_nbg6716-squashfs-factory.bin that was renamed to ras.bin. I had flashed the original firmware prior to that, but this may not be necessary. Let me know how it goes! Oh and if you succeed, check my new post, you may ran in this issue too :

Thanks! I will wait for the hostapd fix before testing ath79. I too use (multiple) virtual interfaces...
@avalentin, thank you for adding ath79 support to the NBG6716!
