Sorry it took a long while. I already sold my DX150 (that I bought for testing ROM alone) to my client’s friend. It took me a while to find unit to test and ended up doing it with testers instead. After confirming the Purist ROM works fine, I rushed and finished it today.

DX150 Firmware version 2.1.293 was released on 1st September 2018 and now Fidelizer Purist ROM version is here. This time I also tested with real device to make sure everything works fine before releasing.

Last version had strange issues and I had to buy real device to test and fix it despite having only few customers but it’s my responsibility to make sure to resolve the case promptly so please consider upgrading if you like free version.

After releasing Fidelizer Purist ROM for iBasso DX150 version 2.10.275, some Advanced ROM users reported the issue about ROM failing to boot properly. It appeared iBasso made some adjustments in kernel and changes I applied on DX150 ROM version 2.9.250 didn’t work anymore.

I also tried revising optimizations based on iBasso DX200 V2 ROM but it still caused boot issue. As a result, I ordered another DX150 unit for ROM testing purposes. This requires immediate attention to resolve the case for customers so you can be sure Purist ROM will work fine.

Now I’ve delivered ROM updates to all clients who requested ROM update for iBasso DX150. If you still haven’t received yours yet, you can request for new ROM through our contact channels and happy listening. 🙂

 

 

Hi. After working constantly on Fiio ROM updates, there’s also DX150 release for ROM version 2.10.275 too. Now DX150 Purist ROM update is ready to install with some new adjustments and improvements based on recent Fiio updates.

Right now I’m working on proper DX200 ROM update. They seem to make some major changes in kernel and changes I usually apply didn’t work on DX200 2.9. First release has issues with some cases in Mango but that’ll be fixed soon.
