Hello,
One of our many NIM-4G-LTE-ST modules seems to have developed some invalid flash contents. We suspect this module lost power during an IOS XE upgrade, wherein XE was silently attempting to upgrade NIM flash during initial bootup after reload. Now we know better. We're running isr4300-universalk9.17.01.01.SPA.bin at the moment.
At any rate, here's what we're seeing as the NIM attempts to boot (taken from 'hw-module session 1/0 ..'):

That's no good. So, this bootup fails, of course, and eventually uboot (or some watchdog component) automatically restarts the board, and it'll attempt to boot again, fail again, and so on.
Getting clever, and noting how WORKING NIMs boot...we then issue a command to manually load what would typically be the correct image, which ACTUALLY DOES exist in our XE distribution, like so.
"cisco-uboot> bootp firmware/nim_cwan_fw.img"
...which results in the following:

...so, in short, a few questions:
A) What in the ever-loving f*** is going on here?
After scouring the internet and annoying various friends who work at Cisco, I can't turn up any information on what exactly the uboot defaults of "f35_fw.img" are all about, and no amount of twiddling with board jumper settings seems to alter the bootup sequence in any meaningful ways.
B) Are there any clues as to where we can find some sort of bootable code for this NIM board type, and recover/reflash this unit after a successful boot?
C) Is there some sort of built-in recovery image we can use within the ISR4k?
Best,
-Tk
