Hi,
I believe the question was about WD03 originally so I will answer about this
The firmware from ravpower might include what we need but it is compressed and organizer in a not easy way,
The firmware file can not be used to flash the wd03 directly.
The easiest way I found is to retrieve the kernel and rootfs while running the original firmware (I know it is too late if you already flash, contact me in this case)
In order to retrieve the original firmware while still running it, is to create shell script on an usb drive and insert in the drive. A specific name of the script needs to be used : EnterRouterMode.sh
Here is the content of this shell script below . Once inserted it will dump the different part of the memory to the usb drive.
now on windows, you can do the following
copy /b mtd4.bin+mtd5.bin+mtd6.bin+mtd7.bin kernel
copy mtd8.bin rootfs
Now you can use those two files to flash your wd03 using the tftp method explain in the wiki
https://openwrt.org/toh/ravpower/ravpower_rp-wd03
The only difference is that it will use the kernel AND rootfs file (openwrt flashing does not have a rootfs file, everything is the kernel file)
Now, if you flash openwrt before doing a backup of your current firmware, contact me , I might be able to help about this, but for obvious copyright reason, I can not put ravpower firmware available publicly.
