Hi all, I need some help to unbrick the router. I have ran into the same issue as referred to in this thread - RG-EW3200GX PRO does not boot after flashing OpenWrt - Installing and Using OpenWrt - OpenWrt Forum . The solution here was to build a new image and then alter the dts.
I have watched and read on how to build an image in debian but there are so much old information that python 2 is no longer use and the image fail to compile. So for someone not being a programmer I thought the easiest is to alter the existing dts as per thread above and from what I understand build the .bin initial flash with that and then the sysupgrade. Could anyone help or guide me to take the altered code dts that was posted and build the .bin and sysupgrade files so I can see if that will unbrick this router. Many Thanks SJ
Start with building an unmodified OpenWrt image for your device (regardless of that of that is useful/ useable to you or not), to establish the process first. Any semi-recent general purpose linux distribution will do for this purpose, the official buildbots are usually running Debian/stable (but that is not a requirement!). Recent'ish OpenWrt versions will build with python3 just fine, only if you want to do OpenWrt version archeology, you might have to use a roughly period correct build host.
I have zero programming skills but I was able to find the dts file here:
git.openwrt.org Git - openwrt/openwrt.git/commit
I then altered it in notepad to the same as what was in this post: RG-EW3200GX PRO does not boot after flashing OpenWrt - Installing and Using OpenWrt - OpenWrt Forum
How do I get a flash image build with this altered dts? Can anyone help as this should prevent others from bricking their device.
Is the dtsi and any other files created from the dts file?
Can the online webbuilder use this altered dts?
Many thanks
SJ

````Preformatted text`If I use the online openwrt firmware selector the ruiji rg ew3200gx pro kernel.bin works and I can open the web gui running in recovery mode , then I go to flash the sysupgrade but nothing happens and I am back to serial, uart and tftp the kernel.bin again. I think it has to do with the mtd , see output below once I loaded the kernel.bin file from openwrt.
Any help appreciated.

frollic I got it fixed, after weeks. I downloaded the RG E5 firmware files and flashed my EW3200gx Pro and it flashed just fine from Luci. So eventhough you hardware model say one thing they probably use it interchange in these 2 or 3 models.
