hello !
congrats for your work.
i have Fiio M9 wich is great but too slow. your kernel seems great. would it be possible to make some improvements? thank you so much
Thats a placebo effect the kernel is pretty much stock. Its great he got twrp made because Ive talked to developers and they couldnt make it either. So I dont understand how. If you want better performance freeze google play services and the player will actually work way better. The fiio sucks I hate it Im so disgusted ill never buy fiio again its got about 10 dollar phone specs.

I believe twrp 3.3.1 and up would root with magisk though thats what we need.

I'm not going to enter once again into a year-old debate on whether my kernel is better or not than stock. There's the geekbench score differences, the ongoing users of my kernel on this forum and others that can attest to whether my kernel is just a placebo or not. As I've said before, my kernel is free and open source for a reason: you can use it, not pay anything for it, and it's up to you whether you continue using it or not.

I do agree with you on two things, however:

1) TWRP was the gamechanger, and porting it to the FiiO X5iii was a real pain in the butt. It was a nonstandard process and even now I'm not sure whether all the functionality is correct. I won't however be able to compile TWRP 3.3.1.x and above as it's lacking some important build elements - I tried a year ago and didn't manage.

2) FiiO does a really poor job of wrapping (great) DACs around poor electronics. 1GB RAM for such a player is abysmal even for Android 5.1.1. And that's before we talk about the passive circuity (solid state devices et al) which really could be designed in a much better RF- and harmonics- based approach.

As things stand I'm not really developing this kernel anymore unless there are a few serious issues with it. The main reason is that I'm not really using the X5iii as a daily player at the moment. I reached out to FiiO recently to see if they were willing to publish all the source code for the M9 and M11Pro, but they kindly declined - which I guess shows their real attitude towards full open source.

I actually have a root guide for the m9 or m11 somewhere I believe I was watching to see. I think it was the m11 Magisk. Yes fiio gave us a 15 dollar phone with hardware and charged hundreds I only paid 200 and I still get pissed looking at it. I just stick with my phones they have 32bit dacs in the flagship phones now. Like the note series why spend 1500 on a m15 just get a note 20 for 1000.

Yes I'll give credit where it's due However you ported twrp is a mystery and I wish I knew to look into it. I don't think you could get bench scores on the fiio it would crash. Lol it's a piece of **** I hate it. But thanks for twrp

Yes it's a root kit for the m11 and firmware. Do you want the stuff I'm updating my tablet but if you want it whe I get a chance I'll load it up

HI, I had install your kernel it is very good. But I have some questions about FIIO X5III
I like playing game so I install some game into my player. but unluckily it cant run on my devices, but RK3188 can run it so,
what is the wrong with that

Are you developing other kernels for Hifi Players?
Sorry haven’t checked this post in a while, just catching up now. It truly depends if the full source code is posted for the respective player. If you have a specific player in mind (and have a link to a github or anything of relevance) then please PM me :)

Thanks alot.
Can anyone give a secure answer, if 512GB SD Cards are working? Im using a Fiio M6 with a 512GB Card, and i want to buy a X5 III.

Thanks
I dont have one, but as TechGuy said - it should work, provided that fat32 is used in formatting. I didn’t implement xfat support in my modded kernel for the simple fact that if you rebooted to stock firmware you’d see nada on the card. I had 2x 400GB cards on the X5III, and they worked a treat.

I suspect it’s got more to do with the keymapping of the player rather than the RK3188 chip. Curious to know what game(s) you think are worth running on the FiiO player :)

Possibly if it’s got the source code for it. Send me a link and i’ll take a look. Incidentally I’m in the market for a new player, ideally one which can be kernel modded. Any recommendations please shout :)

    Dear xda community

    Following on from the work done to date in the active community in the head-fi.org forum, I have decided to post this work on xda to share the work done so far and, well, also elicit help from the best technical community I've spoken to in the past. This thread will solely focus on the RK3188-based FiiO X5iii player, and will thus contain any and all software modifications to the FiiO X5iii. The custom kernel contains the largest amount of new code, extra features and performance improvements for the X5, and really pushes the limits of the hardware to its fullest potential. The benchmarks alone are outstanding - using Geekbench and Antutu the performance is more than 400% that of the current vanilla firmware, and it will similarly feel more intuitive and responsive, as can be attested by the numerous users to date.

    As of Version 3.x, audio tuning is also taken one step further. A new custom AK4490 driver has been implemented, and a significant portion of the redundant and/or unnecessary code has been removed from the sound drivers. Therefore, if not better, the sound should at least feel ‘cleaner’ when compared with previous or vanilla versions. We still have a long way to go to enhance the audio on these DACs, but this driver is a start.

    Installation instructions are outlined further below; ie flash via TWRP, but first-time users can also find a more detailed set of instructions in the zip file.

    There are three versions - the 2GHz version for faster CPUs, the 1.7GHz for most players, and the 1.4GHz version for anyone experiencing random lockups or reboots.

    Unique Features
    - Custom AK4490 DAC driver (faster, better oversampling)
    - Support for DSD256
    - Increased clock speed from 1416MHz to 2016MHz
    - Increased GPU speed from 133MHz to 600MHz
    - Increased DDR speed from 200MHz to 800MHz
    - Better voltage regulation using all possible pwm and clocks on the board
    - Increased available RAM by 20%
    - LZ4 compression for better, faster swap and virtual memory usage
    - ZRAM usage for additional system memory
    - Fsync_disable for much faster system processing
    - UKSM for faster Kernel operations
    - Adaptive-LMK for better memory management
    - Undervolting for lower heat dissipation and battery consumption
    - New Faster CPU Governors: interactiveX, PegasusQ,
    - New Faster I/O Schedulers: zen, bfq, sio, vr, maple
    - New Faster Westwood TCP/IP congestion handler for faster wifi and internet access
    - CPUBoost algorithm for faster on-demand processing
    - CPU SMP feature for powering down unused cores on screen off
    - RQ Affinity for faster I/O scheduling
    - Linaro gcc toolkit for faster, leaner code
    - RK3188 neon vfp3 code optimisation for faster fixed-point and floating DSP operation
    - Full init.d support for script runtime loading
    - Frandom genrator (23x faster than standard random function)

    Thanks and Rants

    Massive thanks to prispewnic from 4PDA for his incredible scripting experience, product features, suggestions and testing, and the great community of beta testers on Head-Fi and 4PDA.

    Thanks also to Fiio for releasing the GPL source code. If it weren’t for you we wouldn’t have this modded kernel.

    Installation instructions

    1) Windows and/or first-time users

    If you already have TWRP or a previous version of my kernel, go to step 2.

    a) If you don't yet have TWRP and/or any previous version of my kernel yet, download the Windows-based loader here and unzip to a folder

    https://www.androidfilehost.com/?fid=1395089523397899882
    (note: you need to have the FiiO USB Windows drivers correctly installed)

    b) Run the AndroidTool.exe program and connect the FiiO via USB.

    c) Put the player in bootloader mode (just as if you were going to upgrade the player the traditional FiiO way with the Windows based loader), by pressing power+pause+back.

    d) If all goes well you should see the green light with 'Found One Loader Device'. Make sure 'boot' and 'recovery_twrp' are selected and press Run. Once done, click the 'Advanced Function' tab and click Reset Device. You should have the new kernel and TWRP installed!

    2) TWRP users

    a) Download the latest version of the kernel (with new optimisation scripts) above and push to sdcard
    b) Reboot to TWRP recovery
    c) Install -> FiiO-X5iii-jkbuha-V3.1-TWRP.zip
    d) Wipe kernel and dalvik cache

    e) Reboot

    f) IMPORTANT: leave running for new scripts to do their magic (you will be prompted to reboot)

    g) Reboot

    h) Enjoy :)

    Any queries, comments etc - please shout :)

    Thanks for the feedback. Yes - reverting to v3.32 solves the Tidal MQ issue. Am working on v3.5 which will fix this bug.

    Thanks a lot for your work, jkbuha. Some friends also have the Fiio X5 iii and they all use your Kernel now. The Player is much smoother and faster.
    I use the 1704 MHz version. For me its the best compromise of speed and battery lifetime.
    With the 2016 MHz version my player gets very hot. Does your player also generate so much heat with this version?

    @jkbuha - I know you aren't developing this anymore but thank you for all the work that you have done to make the X5 III a better product.
