Installation failure (unsupported kernel)

[MadissonG]

A few months back I installed v5.5 successfully on Evolution X on k20pro. While I tried to upgrade today I got this error, although Ver 5.5 still installing properly and working. Kernel being:4.14.327-SOVIET-STAR-//bfed7dee9a.

The new version added code to test whether the user's kernel is supported. Unfortunately getting this error means your kernel is not supported and this modification was almost certainly never working in the first place.

Same thing happened to me, sorry.

See the other discussions under Issues for more information.

Well, with the version 5.5 I can clearly hear it works. Sound becomes quite louder and there's much more details when listening on Tidal HiFi quality. I switched the module on and off (needed system restart every time). Also power draw in kernel manager shows more current draw. Basically the bug is, that kernel I'm using is not on the 'whitelist'. And because of that it won't even install, hich is a bummer 😕

I wish there would be an option to choose to continue.

Can you see if you have any of the following folders in /sys/modules? If you do, then it's working as intended.

/sys/module/high_perf_mode
/sys/module/cpe_debug_mode
/sys/module/impedance_detect_en

[MadissonG]

Just checked, and I don't have any of these.

[theduffster]

Would be highly unlikely it's working then as those are the files it uses, which makes sense, since I think your phone's processor would be too new to support this mod. You can read more about it here: #12

[MadissonG]

Okay. Thanks very much for your help, Yesterday I was wondering for which processors does it work? Might be a good idea to list them. Switching to https://github.com/Briclyaz/NLSound_module_QCom solved everything for me.

[theduffster]

I think the key thing would be kernel support, you pretty much have to assume no stock kernels support it.
