Yesterday I received a message from DX220 Advanced ROM client trying to flash Purist ROM from Mac. It appears the the latest version of rkflashtool in Mac can flash Oreo ROM directly too when verity is disabled. You can check this guide below for additional instructions. 🙂

WARNING: Do not flash iBasso DX200’s Oreo Purist ROM on iBasso DX150 device
iBasso released DX150 Oreo Beta ROM today and some people tried to get Purist ROM from DX200 working on DX150 device. Both device may look similar with the same Rockchip processor but they different kernel and probably different implementation of some parts too.
Flashing DX200’s Purist ROM on DX150’s Oreo beta ROM will not work and it may even damage DX150 device. Right now I don’t have DX150 with me. It’s already sold to fellow audiophile in Thailand but I’ll try to get another unit soon so stay tuned. 🙂
Disable Verity link fixed in DX200 Oreo ROM update
Hi guys. I uploaded my own package with disable_verity.bat but I forget to update the link last night. Now I’ve updated the link in DX200 Oreo ROM page so you can download my package with disable_verity.bat file from this link below. 🙂
iBasso DX200 8.1 Oreo beta ROM impressions and Purist ROM possibilities
EDIT: Well, I released Purist ROM for iBasso DX200 with Oreo update now. 🙂
Hi, everyone. Oreo beta ROM came out yesterday for iBasso DX200 and I spent all day and night testing and checking things out. So far sound quality seems to be promising though I’ll miss Purist ROM optimizations until preparations are ready for Oreo ROM.
Current Oreo ROM can support LDAC through developer options and force bluetooth detection option which is good. UI is more responsive in launcher but Mango is about the same. MangoOS seems to be better though. However, file access to storage is slower than 2.10.215 ROM.
I think I’ll port new files to 2.10.215 ROM to use for time being until they improve file access performance in next version. If you don’t change micro SD card and re-scan frequently, you may try using Oreo ROM for a while with bluetooth headphones.
As for ROM modding potentials, it doesn’t look good. I can repack and flash update.img safely but repacking system.img and vendor.img will freeze at logo screen. I tried many ROM cooking tools and bought few more that supports Oreo ROM but no luck yet.
Well, this isn’t the first time we have obstable as I reached out to iBasso and they released Factory image and flashing tool for me to build the world’s first DX200 custom ROM with Play Store and some optimizations to improve device performance so they may lower restrictions after it goes public.
For worst case scenario, I can still modify the ROM to some extent but it’ll have limitations with current situation. I’ll continue my research for Oreo ROM modification. I already informed iBasso about the situation and hope to hear back from them soon.
