I mod zbt-wa05 with a 16MB FLASH(W25Q128) instead of original 8mb w25q64.  In the sdk,I changed target/linux/ramips/dts/ZBT-wa05.dts as below.

http://s6.sinaimg.cn/large/005HbPEYgy6M … d5&690

In target/linux/ramips/image/Makefile,I changed Default8M to Default16M

I thought it was done for the mod.But the leds are not working except wan&lan.Any expert can help me fix it?

Hello
I have the ZBT-WR8305RT from the same company, try this dts file and see if your leds come up. You might have to edit your flash type.

Is this dts given you by the stuff of this company?

I got a complete sdk from this company, so this is direct from it. the only thing I'm missing is the bootloader since mine is made for their market I'm unable to read the file recovery screen.
