POST-INSTALLATION SUGGESTIONS

GAPPS COMPATIBILITY
No matter how hard I tried to reduce the ROM's size, OpenGapps Nano have never worked properly due to extremely low free system space. So either use Pico, or repartition your phone.

SETTING UP MICROG
Signature spoofing is supported but not enabled out of the box. There's no switch to enable it in Settings, you must grant its permission to each app that needs it. In particular, if you install MicroG (either via the apks or via MinMicroG), you must run these commands in a root shell:

pm grant com.google.android.gms android.permission.FAKE_PACKAGE_SIGNATURE
pm grant com.android.vending android.permission.FAKE_PACKAGE_SIGNATURE

then make sure all the checkboxes in MicroG's status screen are ticked and reboot.

SETTING UP VIPER4ANDROID
If you follow these steps carefully, you'll manage to install Viper4Android while keeping Enforcing SELinux, and it will survive across ROM updates too

First! I'm happy to finally see a real thread for this.

Perfect combination Sultans camera and idprophecy ROM.
question- can charging rate be varied using kernel auditor mod app?
Because whenever I'm installing a ROM having sultan customisation included my OPO charges very slowly(180mA).

I don't know if KA mod has that feature. However it's possible to change the maximum charging current intensity with any text editor, check the second post of Neon kernel's thread: I've explained how to do it. However is the problem occurs only on sultanized ROMs, it might also be that the different battery driver thinks that your cable is faulty, and so it reduces the charging speed. I've had a similar issue when using the Linux 3.10 kernel on my phone.

KA mod sure has that feature if kernel has support for it

 

[Tomoms]

OK, the kernel supports it, so there should be no problem tweaking that value.

Thanks for the reply. On your ROM my OPO is charging normally. Actually I was asking can the charging rate be varied in your kernel because in most of the kernel it is disabled. By the way I just installed this ROM awesome ROM but I'm experiencing slight lag in UI.

I've tested v10 of your kernel last weekend. I also had lags while scrolling. Did you remove cpu and touch boost? Couldn't find settings in cpu section of adiutor mod. Or are they managed in governor settings?

@Tomoms

Nice of you to share your work. I was just crying about for a ROM (Sultan base + OMS) and a good person linked me here. As it's relatively new I'm very optimistic

I have a couple of questions:

Have you tried your ROM with Xposed? (I just switched to Nougat (ViperOS) and the SOT is terrible. I'm trying to see what the cause is)
Is this version of your ROM based on Sultan's Oct 22 release?

I have only one phone at the moment and can't risk it with testings. My choices are reliant on your answers and the Epic XDA Community. Thanks in advance...

CPU boosting is present but KA doesn't support it, so it looks like it's missing but it's actually working in the background.

Nope, I don't use Xposed nor have I tried it.
The release doesn't include all the changes brought by Sultan in the 22nd October build (it includes one out of two of them), however this is not a problem, because the change I left out is a small reversion related to in-call volume that was made by him only because "users were not amused" by the improvement. So the only thing this build doesn't include is not a fix for a bug, just a small volume adjustment decrease that was made because nobody noticed the increase that was brought in the Spetember 30th build, so there's nothing to be worried about. This build is just as good as Sultan's last one.

Hey just to clarify is this based on sultan lineagos? I can see stuff committed by sultan

Read OP.

Yup, with his personal kernel and substratum support..!!

 

[zalamandra]

Yup, with his personal kernel and substratum support..!!

And f2fs support too!

 

[Setting.Out]

And f2fs support too!

Looks like that's been removed, but another file system looks like it's being implemented (at least partially).. #sdcardfs

Massive overnight battery drain

 

[JJohnson1988]

I'm so excited that my two favorite bacon ROMs have been merged together! Thanks for the effort.

Two things I have noticed for now:
- Camera appears to crash when snapping an HDR photo (similar to LineageOS camera's behavior)
- Quick unlock for four-digit PINs doesn't seem to work

They are two different things, and both are present in my ROM+kernel.
