Thanks a lot!!

any chance to have someone to write a brief guide on how to do the flash? i know how to flash rom for fiio x5 III, DX160.... is the step similar ?

I am using the custom kernel from https://kernelmods.com/#stable_x5iii_ck For fidlizer, I don't think it will give you the kind of performance gain as the custom kernel.

After installing Lurker's firmware add-on, is there anything I need to do so that my dx160 acts as a USB DAC? I installed the driver, connect dx160 to my PC, set the USB mode as transferring fuke, then turn on the DAC mode in mango player. but my windows10 just cannot recognise the device.

simply install the standard one (medium speed), if it does not work, then install the slower clock speed one. if it works and if you insist in getting it running as fast as possible, then install the highest clock speed one. Otherwise, just enjoy!

TiborG, can you kindly outline how to install those packages?

thx for sharing. But I found that when I opened the RAR file, all folders are of 0 size. anyone encounters the same issue? UPDATE: the problem is probably caused by the fact the the rar file is using new version of rar. I use 7zip and can extract the files Anyone had tried these files?

have you tried to flash back firmware 1.2.1 via the official firmware upgrade tool?

full TWRP backup fw 1.2.4?? do you mean we can first flash fw 1.2.4 and do a backup from TWRP? Then in the future, we don't need to install fw1.2.4 from scratch (which will result in hacing TWRP removed) again?

just flash that ...... and then upgrade from 1.2.1 to 1.2.3

use the official firmware upgrade tool, see http://fiio.net:8000/forum.php?mod=viewthread&tid=41890

In short, better performance, longer battery life you can refer to https://www.head-fi.org/threads/fiio-x5-3rd-gen-2x-akm-4490-balanced-out-dsd-dxd-dts-android-dual-card-slot.828402/page-968#post-14797406 to get the changlong for jkbuha's kernel (which I have also extracted below) Changelog...

I would suggest going for OFW 1.2.3 + X5iii-jkbuha-V2.7-TWRP

I will rather wait for fidelizer ROM 1.2.3 instead of installing the stock 1.2.3
