Hello all. A quick question, just what qualifies as a "sysupgrade-compatible image" and is there a way to test whether a certain .bin file I have is or isn't sysupgrade compatible?
I ask because I installed LEDE on my old Linksys E4200 v1 and realized that it does not allow 802.11n, only (b/g) is available. I'd like to switch to Advanced Tomato (which is a based on Tomato Shibby), but am unsure if its .bin file is sysupgrade-compatible image.
Barring being able to move directly from LEDE to Advanced Tomato, can I revert back to the original firmware from Linksys using the webgui? I'm currently on the following LEDE version:
root@Buffalo:/tmp# sysupgrade --test openwrt-lantiq-xway-WBMR-squashfs.image
Image metadata not found
Use sysupgrade -F to override this check when downgrading or flashing to vendor firmware
Image check 'fwtool_check_image' failed.
I assume this is what you were referring to with sysupgrade not accepting an image.
CC may be ancient but it works whereas DD and LEDE don't.
