An OpenWrt sysupgrade will supplant the entire current OpenWrt installation with another version. This includes the Linux piece and SquashFS/ext4/ubifs/JFFS2/other operating system partition/s. This is NOT equivalent to a first time installation (factory).

Sysupgrade via LuCI or CLI works by optionally saving specified configuration files, wiping the entire file framework, installing the new version of OpenWrt and afterward restoring back the saved configuration files. This implies that any pieces of the file framework that are not specifically saved will be lost.

In particular, any physically installed programming bundles you might have installed after the initial OpenWrt installation must be reinstalled after an OpenWrt overhaul. That way everything will coordinate, for example the updated Linux bit and any installed bit modules.

Any configuration files or information files put in locations not specifically listed as being safeguarded underneath will likewise be lost in an OpenWrt redesign. Make certain to check any files you have added or customized from a default OpenWrt install to back up these items before an overhaul.

OpenWRT overhauls itself by saving configuration files from known locations (in addition to physically defined files), overwriting the partition with the most recent firmware and afterward restoring the saved configuration.

This typically works for the configuration itself, however the interaction doesn’t deal with any custom bundles that were previously installed physically (either through LuCI or with opkg). These bundles should be noted down ahead of time and afterward reinstalled. This can be done physically or partially automatic using opkgscript.

This requires a decent degree of equipment and firmware understanding, as well as the right equipment tools. For instance, you would require a revamp microscope. And specialized soldering tools just to connect improve wires to fine-pitch microprocessor leads. In a couple of cases I’ve seen routers have their firmware in serial blaze chips. Which makes it possible for you to simply sneak around on the serial lines during boot.

In any case, when you then finally have the firmware, it is not that simple to edit them. It would require that you are skilled in the specialty of picking apart, and programming advancement. Regardless of whether you modify the binary files directly in a hex-editor. The general checksum of the file would likely keep you from updating the router with the firmware. There are techniques for overcoming the checksum issue, however it is complicated — another layer to get through.
