RG-EW3200GX PRO does not boot after flashing OpenWrt

Installing and Using OpenWrt
21

Perhaps this indicates some progress:
I was able to boot the sysupgrade.bin image from TFTP (just to clarify this is the same imaged used during the initial install downloaded from https://openwrt.org/toh/hwdata/ruijie/ruijie_rg-ew3200gx_pro)
The @frollic image aparently did some changes to the mtd partitions during load
Here is the console log (and mtd / mount info at the end of the log)
Notes:

if I try to flash the image to the mtd (via sysupgrade) the router doesn't boot up with error
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
(will provide complete console log in my next post)

Well, another try

followed https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=ce8a33b021a703b1933f627835f6cdc88c0ecdd3

Back up firmware(mtd7) partitions with:
        dd if=/dev/mtd7 of=/tmp/firmware.bin
   and then download the firmware.bin image via SCP.

en switched back to the "briked" RG-EW3200GX PRO and tried reverting to stock firmware using the steps provided in the url mentioned before **(DID NOT WORK)

so......... what's going on???

so far I have to conclude that the information provided in the URL is NOT WORKING

Hello!, hope you all are ok!
Any advice or tip anyone of you can give me in order to unbrick the RG-EW3200GW PRO ?

So far, I'm wondering if other users could get into the same trouble by using the images and instructions published in the OpenWrt web

I have limited developer skills, but I'm willing to try to help in any possible way:
to diagnose if there was a hardware change (vs the devices I own and the published images)
provide a remote session for someone to do some debug
build a new image?
add a warning to the web alerting that the wiki might be innacurate

Thanks a lot!

first device, you are right, I did not follow the exact procedure (my mistake)
second device, used the exact instructions and got the same problem...
and the recovery to stock procedure didn't work either
also the 5.0GHz radio is not recognized booting the -sysupgrade.bin neither the initramfs.bin

just to follow up, I was able to restore the stock firmware.
So far the whole problem seems an MTD partition layout mismatch, causing the sysupgrade to be placed in the wrong offset (bricking the device)

This is the stock firmware booting:

This is the output using the initramfs image mentioned for the install procedure in the OpenWrt git/website:

So, following the install instructions and next doing a sysupgrade the result is a bricked router:

Well, got it working. Step 1 Built a custom image, changed mt7622-ruijie-rg-ew3200gx-pro.dts to match the proper mtd offsets (matching the stock firmware) and voilá! OpenWrt booted up just fine, and only then the 5G drivers loaded properly. Step 2 built another image with Luci pre-installed. Step 3 extensive testing (still in progress).

Bellow some screenshots:

Hello everyone! Can you help me with a full dump for SPI programmer for this router. Partitions MTD made with openwrt are also good. Any help will be appreciated. Thank you!

Hi, I'm facing the same situation now. I have a question about how to build your own image. I can extract dtbs from openwrt firmware. Maybe I can convert it to dts then change to right partitions and recompile to the dtb. But I'm not sure what to do next. Can you help me?

Hi, have you considered contributing your changes to the official repo?
