I've noticed this with a stack of E1200v2's, E1500's, and E1550's lately. I'm wondering if broadcom-k26 series is broken for these specific devices. I then tried them on broadcom-k3x and they work great, even with the most recent build. The E1200v1 wasn't so lucky (4MB of flash) and had to go back to 43136.
EDIT: The only way I could reflash them is through serial console and entering "flash -ctheader : flash1.trx" and tftp upload.
Code:
Image 1 is OK
Try to load image 1.

I presume you are flashing the generic mini k2.6 nv64k build on your 4MB flash devices. Trailed build should only be used for initial flash. Thanks for the report! _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Actually, no. This was doing an upgrade on an existing device already running dd-wrt. It was running a rather old build from 2018 and went to upgrade it. This was the result.
I tried flashing through upgrade, along with going straight through the CFE using a trailed build. Same result. I ended up switching them to the K3x build, except for the lone E1200v1.

The E1200v1 is the one I was referring to as far as mini nv64k upgrades (ref: E1200 Wiki). After initial flash, you need to be on at least 40723 for all the shell-related patches (ref: #6373)

All I can say is not to use any build older than 41664, to have SFE NAT (for k3.2+ builds), KRACK (k24+), PBR+SFE, CAKE / FQ_CODEL_FAST, and GTK Rekey wireless timer fixes. For Wireguard, one should use at least 42872.
There may be some builds in bewteen the wiki inital flash and present that may not play nice as far as webflash upgrade, tftp, or serial, as you've found out.
