Yeah, although I think the problem is somewhere else. You might have an undervoltage-induced error only because of one of the frequencies. So not all the voltage settings, just a particular one.
And only that one is giving you trouble. It was like that with my Z5C. Ofc, if you get more reboots then either your voltage for the problematic freq is too low or you have several problematic frequencies.

Apart from that, my Z5C is pretty stable. So if there is an error, it's from a race condition somewhere that's exacerbated from the inaccurate voltage tweaks. :)

I think I tried setting all voltages individually, as GreyLeshy posted in a screenshot few posts back, but something made me unable to set it exactly like that, after changing a specific one, it automatically changed another. I will give it another try to explain this better.

That means your phone can't take it. Don't use his settings blindly. They don't work for you.

Actually I managed to set it like that and haven't had a reboot yet. Didn't do any longer calls than like 30 minutes yet though, so I'm still to discover if it's gonna continue. Do you have any idea what's causing it, any hunch? You were one of those who didn't have this issue until quite a while after, right?

Regards,

Nah, i still have issues, albeit very rarely. With lower than current voltages I have many more restarts. Find stable voltages. Or stable enough that it isn't an issue.

Still been working for me, I'm very surprised. When I had the issues I just used the global bump setting until it was stable but that was too much and noticed heat and battery life drastically decreasing.

I'm just WAITING FOR IT, and my tiny bit of happiness is gone again. ;)

Is it possible to have a version underclocked by default so we can have temp and battery life improvement? Like zombie kernel that was 1,344/1,536GHz by default.
Thank you

It's been months since the last reply. Also, it's something easily doable by yourself and it doesn't warrant another release. So definitely not.

Is it possible to pass SafetyNet with this Kernel? I am using E5823 on Android 7.1.1 firmware 32.4.A.1.54. Using Magisk v20.4.

However, SafetyNet check gives me:
ctsProfile: false
basicIntegrity: false

Where might I have gone wrong? I have the following Magisk modules installed:
Busybox for Android NDK
Custom Thermal Mod (FSC)
Debloater
Systemless Hosts
Xposed Framework
Youtube Vanced

And the following Xposed Modules:
Dimensions Editor
Greenify

I am very thankful for help :)

PS: Also I do not understand what OP root: magisk + module init.d means? I cannot find the init.d module anywhere :/

Magisk has an addon.d folder. Use that, it's better. Also, you won't pass CTS with Xposed installed. That's the whole point of Magisk, not modifying /system in order to help pass SafetyNet.
