Hi, I have this situation. I used to upload openwrt via ftdi and I made a mistake and my mr18 got bootloop.
When I received usbjtag I was able to connect and uploaded original_kernel.bin from the original_mr18_kernel.rar package from the forum. I uploaded to kernel1 and kernel2 - now the terminal no longer has bootlop, it only has this screen:

Now it's hard for me to enter TRAP ON mode and if it succeeds, the DETECT command resets jtagant - as in the picture.
Is there any advice for that?
