Hello guys. While I was working on iBasso DX200 2.5.141 ROMs, I received order for Fiio X7 Advanced ROM so I need to deliver his ROM file within 24hrs so I hope a little delay wouldn’t hurt as I’m also testing some new stuff too. Here’s information about Fiio X7 Purist ROM.
-Based on official Fiio X7 3.3.0 ROM
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-build.prop tweaks for better video and storage performance and improve battery life
-bundled audio effects removed but keep main engine (Poweramp works now)
1. Download Factory Tool provided by Devin http://www.mediafire.com/file/0yztdw6qdpwwp9a/X5III+Firmware+Upgrade+Tool+with+FW1.1.1.zip
2. Turn off Fiio X7
3. Connect X7 with USB connection to computer while holding previous track button
4. Install RK USB driver included in Firmware Upgrade Tool and replace update.img image with mine.
5. Open X7 Firmware Upgrade Tool.exe and flash ROM according to instructions provided in Instructions of How to Use the X7 Firwmare Upgrade Tool.pdf
There’s a lot of improvements for Advanced ROM and I also added Enhanced ROM into collection too. Please read Portable Products for more details including Fidelizer Mod project to further enhance Fiio X7 product with hardware modification.
