Ouch. That does not look good if it is a consistent result. I believe this device ID is used by Qualcomm for one of their chip internal bootloader failsafe stages. This could mean that there is something wrong with the flash on the modem, casuing the modem bootloader to fail. There is no easy way to fix this. If you Google the device ID you'll find a number of recipes for rescuing phones with this problem. But you'll need a file with the next bootloader stage to do that, and I'm afraid we don't have that.

Does the modem now show up like this on other systems too? If not, then this could be a temporary issue related the OpenWrt system (e.g. power issues), or some software issue (e.g. a mode switch command that made the modem firmware crash).

On a separate note, there is no package eject .

You are right. Sorry for the confusion. I just looked at the current set of packages and didn't notice that this is a pretty recent addition, which isn't released yet:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=fcfb9e4ded51dbba4be33562b73c94f5fd8f1fdc

So you're right. There is no such package in any OpenWrt release.

But it won't help anyway as long as the modem is in that mode, since it only presents a single Qualcomm DLOAD function (as displayed by the Product string).
