[solved] Unbricking LNU23SL Mainboard (NAS4220 Clone)

Hello,

i am trying to unbrick my nas with a LNU23SL Mainboard (ver. 1.21). This NAS seems to be similar to the NAS4220 from Raidsonic, but the Manufacturer is Seenergy (NVR 104).
On this NAS i get no response in the serial console after flashing a new firmware to the device. So i think that only a JTAG recover is possible.
I have build an unbuffered JTAG Adapter an soldered the connections to the mainboad. Also a short connection from pin1 to pin 17.

Now my problem:
The Nas_FlashTool has detected the JTAG-Adapter and the Device (Device is in Debug Mode, SL3516 CPU found, etc.) but it says every time that there's an unknown flash type. On the mainboad ist a MX29GL128BEH2-90G Flash.
Can somebody help me?

Thanks in advance.

I have added a screenshot from the FlashTool with all informations.

Welcome Anthrax6937!

Ok, we have to check if the MX29GL128BEH2-90G is compatible to the other flashes being supported.
We have to make a new release of the tool which will take some days. When it's ready I send you a test version.
