This is my second e7350. I purchased this one after successfully getting openWRT running on the first one. The plan is to have a roaming WiFi network with AP at each side of the house along with two VLANs, one for IoT and one for data that should not leave the house.
There used to be a great walkthrough on the e7350 that I used to set up the first router. I cannot seem to find it anymore. The closest thing is the E8450, but that doesn't seem to follow the path I remember.
My current predicament:
I was having issues getting to the Linksys UI on the router, so I went straight to JTAG to attempt to update the firmware using TFTP. This seemed to work, except the router now doesn't boot at all.
U-Boot still comes up, and I can select reload options, but an attempt to boot results in the system halting with an "invalid image" error.
Alternatively, is there a way to simply clone the device I have that works, and load it to the broken one?
There is this long thread about the e7350, including some stuff that I tested/learned when installing it myself. Hopefully this will steer you to some answers. It would probably be worth trying to install the vendor firmware again via TFTP, assuming the link shown here still works (it is working right this minute, but cannot speak for weeks/months/years from the writing of this post in Dec 2024; this version will allow you to install OpenWrt from the vendor UI).
at some point in 2022, Linksys started signing the firmware, why is unknown as there is a warning on the linksys firmware page that you need to upgrade to the unsigned version before installing the signed version.
You may be on the signed firmware, Ver. 1.1.00.033 (Signed), so you will need to tftp back to Ver. 1.1.00.032 (Unsigned) to recover and stay on this to install Openwrt.
They did the same with it's Belkin counterpart the RT1800, there's threads on that as well if you need anything further.
