hsi0409 Posted July 25, 2020 Share Posted July 25, 2020 Hi I tried to update flash memory using Line 6 Monkey and an error popped up. So I disconnected the USB cable and power of HD300. and when I turned on the HD300, the screen remains blank. How can I fix this? I tried to do Factory Reset by pushing A button while put the power on. Nothing happens. Now when I connect the usb cable between the unit and computer, The Line 6 Monkey detects the HD300 but I cannot perform Flash Memory update.

hurghanico Posted July 25, 2020 Share Posted July 25, 2020 AFAIK unfortunately the POD HD300/400 don't have a safe mode (eg like the HD500) which can be specifically used to flash the firmware when the device is basically bricked, but only the Factory Reset mode (hold A while powering on) and Test mode (hold Tap while powering on). However you might want to try some of the proposed solutions I've read on a post on facebook written in thai language: How to Fix for Update Firmware Failure for POD HD300/400 By PHOLROCK I guess you'll need to use google translate, unless you are thai. I can't help more given that I use an HD500. Good luck. _______________________________________________________________________________________________________________________________________________________________________ All about POD HD500/X help and useful tips Quote Link to comment Share on other sites More sharing options...
nickkucel Posted July 27, 2020 Share Posted July 27, 2020 I had the same problem. The update process would give me an error message. So I read the page the guy had written in Thai. The solution is to use a different (newer) computer and a different USB cable. Quote Link to comment Share on other sites More sharing options...
hsi0409 Posted July 30, 2020 Author Share Posted July 30, 2020 I called a distributor(in Korea), he said it might be mainboard problem, if it is, it will cost so much (like 200 dollars) . I gave up.. cannot use this HD300 anymore.. Quote Link to comment Share on other sites More sharing options...

I gave up.. cannot use this HD300 anymore.. I doubt very much that a firmware flashing procedure could physically damage a mainboard in any way. Unfortunately I don't know of any other ways to properly install the firmware on that device, but for me the problem is just that, and a Line6 technician would know how. _______________________________________________________________________________________________________________________________________________________________________ All about POD HD500/X help and useful tips Quote Link to comment Share on other sites More sharing options...
Groot1 Posted April 19, 2023 Share Posted April 19, 2023 I was able to install a firmware on the tas1020b component and it recognizes it as an audio device. Having the correct firmware I think you can fix it because the one available for download is too big and doesn't fit on the component. PS: I bought it already with a firmware problem I thought it was just an update but I lost money and I'm just curious so I might be completely mistaken Quote Link to comment Share on other sites More sharing options...
