I have a big problem. Actually I have 5 Merikai MR18 devices which all have the same fault.
I could flash all of them with USBJTAG NT, flashed is the Firmware Version OpenWRT Designated Driver r47958/Luci Master (git 15.354 ...
I have access to the router via webui and can log in. When I change the root password for example this will been saved, until i disconnect the device from the power Supply, if I do so he will lost all changes and the standard settings are set. looks like the information will be only stored in the RAM.
When I go to System/ Software there is no free space shown.
When I try to upgrade to LEDE, the process will hang and after reboot the MR18 is broken, I have to reflash.
I have tried to configure the MR18 as I need, works all fine, but when I unplug from power supply, all is gone.
Has someone an idea or an solution?
I have flashed the MR18 with the instruction from Ricardo Cooper on youtube, three times it worked very well.
That is right, extremely old, but this is only the Firmware I am flashing, after this i will upgrade to the newest version, usually. For the MR 18 I use the openwrt-ar71xx-nand-mr18-initramfs-kernel-ecc Kernel.
I have tried several time to clear the storage, without success, in the Software section there is no free space shown, and this is, I think, the problem.

Since you're not showing any free space, and losing all your settings after power-off, it sounds like you're running in RAM only without any storage mounted. That would make saving your settings impossible.
Hello, thank you for your support. But the problem is that I have to flash first of all the openwrt-ar71xx-nand-mr18-initramfs-kernel-ecc.bin and with this firmware I have no chance to upgrade to a newer or different version, because this firmware, as you mentioned, will be load in RAM only. So the problem is I can not write anything on the MR18.
Hi, I know this is old thread but I bet many people will find it having the same problem so .. in my case the problem was that I was making a mistake during the programming with USBJTAG NT. I did all the Read and Erase and Write but just before the write of the bin file I did not click on Kernel 2 tab which means, that I was rewriting the whole flash as I was on AllFlash tab. The correct procedure should be to Erase kernel1 and kernel2 then open the bin file then select the Kernel2 tab and then Write. I had to debrick my MR18 twice before noticing this small detail. If you do the same mistake you will get this exact behaviour - zero free space, no settings stored and not possible to upgrade. Hope this helps.
