Hi guys, need to share here..
So my problem is not solved, then the kemper support by email suggests me to send back the unit. They give the address, ups code ect ect
But i live in indonesia, the shipping cost will be too much. So i buy another unit to give it a try. The second unit is coming today. And once again, when connect to PC, the RM ask me to updating. I hesitate to update because of my first experience, but i still need to connect to RM to setup the pedal. So i need to updating. Then i update via OTA, but same thing happened. The unit error. 6 red led. Try restore, try factory reset, try update via USB, try 4 USB. All no solution. I am getting frustated, 2 unit with the same problem
Then i try contacting kemper again, this time via their chat support (web). Now their reps suggests me to downgrade the os, he send me another kaos.bin file (not the same from their web). I try and it work! Now may kemper player working normally. Two unit, all safe. Connect to RM, no problem. I dont know what the real problem is, but this solution work. So if you have the same problem, try to downgrade
Thank you
