The version of the kernel you’re quoting isn’t recent. Look at the post on the last page I quoted, links are all there.

Oh yeah I should be installing 2.7, whoops!

Dear Head-Fi community,

Whilst working on upstreaming the kernel to a more recent Linux version in order to support more features, I’ve come across a substantial amount of performance-enhancing functionality that is worth releasing in its own right. So I’m very happy to announce a performance-specific release - Version 2.8, which is between 20-30% faster than Version 2.7. This brings out the best in the limited capabilities of the Rockchip RK3188, and whilst it will never match the CPU performance of the FiiO M11, it provides a very fast and responsive experience in terms of usage and feel.

Changelog

Version 1.0
Initial system release and branch-off from FiiO GPL code

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) here:

https://androidfilehost.com/?fid=1395089523397926869 and push to sdcard

b) Reboot to TWRP recovery

c) Install -> FiiO-X5iii-jkbuha-V2.8-TWRP.zip

d) Wipe kernel and dalvik cache

e) Reboot

f) IMPORTANT: leave running for 1-2 minutes for new scripts to do their magic

g) Reboot

h) Enjoy


Thanks and Rants

Once again, massive thanks to prispewnic's scripting and product features, suggestions and testing. Thanks to the great community of FiiO users, both on Head-Fi and 4PDA,

Thanks also to @FiiO for fully supporting the GPL license and releasing the source code back in June. If it weren’t for you we wouldn’t have this modded kernel.

Version 3 is ongoing and hopefully will be released in the coming weeks; this will be quite an ambitious project as the Linux source code will need to be upgraded from 3.0.101 to 3.18. Small numbers, but equivalent to approx 100,000 lines of code...

As always, any queries, comments etc - please shout.

PS: @moderators - could someone please pin this to the first post of this topic? It's a real shame that new users have to trudge through 1000 odd pages before they get to this...

Question: Is it still an issue running Fidelizer? I ran into this when trying to install one of your latest versions and didn't mess with the work-around suggested as I'm not all that code-savy.

Yes but as long as you clear some space in the system partition you'll be fine. If you're not comfortable with changing /system then I'd suggest you reinstall FiiO vanilla 1.2.3 to use this kernel.

I decided to nut up and give this a try, but when I connect the device via USB, then press power/pause/back, it just takes a screen shot. What am I missing (besides perhaps opposable thumbs)?

Works best when the device is off, but it still works even when it's on. Keep them held down. Release power at welcome logo and the other two when you see TWRP.

If you're using command prompt or terminal it's easy to just enter 'adb reboot recovery' .

You're not doing anything wrong, otherwise. Just hold them down.

2.8: First Impressions

I keep my album artwork at sizes that are wholly unnecessary (appreciable on a larger display but I don’t feel like having to retag everything for X5 or vice versa). Were they optimally sized at 600x600 I’m sure they’d load instantaneously. Now even those 1200x1200 & higher are loading in noticeably faster.

 

[Preachy1]

Okay, I figured out how to the option screen, but when I scroll to Boot Loader Mode and press enter (which I assume is the power button), the screen goes black and nothing more happens.

That’s not whatcha want, my friend. It appears you have not installed the custom recovery successfully.

If you’re trying to simply enter boot loader mode it’s done by plugging your powered off device into a usb cable (connected to your pc) while the previous track button is held down.

 

[Preachy1]

Thanks for the help. My thumb is getting sore! I'll try again later on

Can't wait to try it out... still waiting on the replacement battery, but now I'm even more eager!

Geez, you were not kidding about the speed increase.

Thanks for all your work on this DAP. You turned it from a buyer's remorse to a daily driver.

 

[MinnieOne]

EDIT - never mind, went back to Witzyzed instructions and that cleared it up for me.

Finally decided to install the jkbuha and I'm lost right at the start. The Android Tool "No found Any devices". I've go the USB 4.47 drivers installed. What mode does the X5 have to be in? Help.

 

[etoilebiscuit]

Dear all, I've been facing this problem where in FiiO music app always have a prompt, exception occurs and then application crash and restart.
Any fix around on this?

 

[HungryPanda]

I always get it when something is playing from 1 card and I try to pick something from the second card, bang app crashes then restarts
