Some problem fixes:
-if you get random reboot use oreo go mode.
-Recommend kernel manager settings :
Cpu speed max 1.4-800min and set governor İnteractive
-add this line to buildprop for smooth animation transitions.
And now you ready to use this beatiful rom

It's looking good. No problems so far :fingers-crossed: I've been testing it for a few hours.

TWRP 3.3.0-0 i9300
Format data & advanced wipe
Viper-i9300-20190629-v5.2-UNOFFICIAL.zip
open_gapps-arm-8.1-pico-20190712.zip
I've installed 22 apps.
Usage: Internet only.

My observations after few days.
This ROM is very similar to the Team InFusion FireHound v4.9 Oreo 8.1 ROM, for example (when it comes to functionality). The main advantage (for me) is the option to remap hardware buttons :victory: and the ability to wake up the phone by home button (it's important to me because it's uncomfortable to press power button if I'm using dedicated powerbank), it also has the option (in dev options) to kill apps by pressing the back button for a while (it's helpful to me, sometimes I have to use it). On the other hand, I miss one small detail - possibility of placing the date in the status bar.

Secutity updates are from March 2019.

This is where the good news ends

Unfortunately, this ROM is rather no stable for me.

During these few days, the phone was rebooting itself few times in completely different scenarios, sometimes I had to remove the battery, because it didn't responding (it was hanging on the boot screen). It also reboots itself to the recovery mode

which is the same as with ViperOS V6.5 Pie ROM, it was described here by another user:
https://forum.xda-developers.com/showpost.php?p=79898907&postcount=12

After installing the "GO mode", this ROM has become unstable even more, I don't understand why. I constantly get an error telling me that the "setting are not responding", and I need to restart it. So I uninstalled "GO mode", but the problem has remained. I couldn't get to the settings

at all.

It's a shame, because it looked good.

Thanks.
With fresh install, "go mode" is working properly. I had "error 4" again, but it just irrelevant information, patch was applied successfully, I checked in terminal with "getprop | grep low_ram", and everything is OK, "go mode" was enabled.
This time I'm not going to touch anything in the Kernel Adiutor

I like this ROM, it has probably everything I need (as for Oreo) :good: I hope now there will be no more problems with self-rebooting.

Well, after couple of days I can tell that "go mode" didn't help me. This ROM keeps rebooting itself. For example, I can't browse the Instagram for more than 5 minutes, because amount of RAM drops below 100MB and the app starts to stutter, which ends with reboot. Some weather apps behave in the same way.
I didn't have that kind of problems without "go mode", which is weird. Although the phone sometimes rebooted itself, but the stability of the apps was fine.

So for me, it looks like this: With "go mode", no sudden, itself reboots, but very unstable behavior of some applications, bad RAM management. Without "go mode", the system can reboot itself at any time, but the apps are working fine, very good RAM management. I'm monitoring RAM with app called "RAM Monitor", it has flowing interface, so I can see exactly how much of free RAM is available at any time.
It could be more than just a matter of RAM memory.

Either way, is no good.
I have similar observations about the FireHound v4.9 Oreo ROM.

How many post I see every rom are bad for you. Why you not going back to stock rom?

I'm very grateful to the people who spend their time creating more ROMs for this phone.
In the last four months, I've used over 20 different ROMs, just out of curiosity, I was looking for something newer than 4.3 Jelly Bean. Only one of them (LOS14.1) is almost 100% stable for me, I've been using it for a month, under different conditions. The second one (PixysOS V1 Oreo) has very, very good prognosis for me. The remaining 18 ROMs were unstable.

Yes, I know how it works. I can compliment a good ROM all I want, but if I write that something doesn't work, I'm supposed to provide evidence to prove it (logs etc.), otherwise, I annoy the person/team who built it. I rarely have the opportunity to debug, collect logs etc., especially when issues have a random nature. So from now on, I'm not gonna write anything about bugs and issues anymore, I know it doesn't matter much. I think I have found a working and stable Nougat and Oreo, maybe someday I will find Pie, then I'll mention it.

Thanks for your comment but I dont say anything stable for oreo thread
some roms stable for dailyuse but roms status still beta or alpha mate
there are people who are already interested in making these resources better
I just built it different roms with same sources.
There is no such thing as every rom will be great.
ı do some of my own development with already existing resources,
I did my best
users who do not want or do not find them "stable" by themselves. may not want to use. their choices
I don't care

Status: Stable ?

How can you talk about stability when the SELINUX Security section is permissive?
I should have Status = Beta

If you really want to talk about stability, put SELINUX in Enforcing

Stable not mean enforcing
if all functions are running smoothly in a rom, that rom is stable. And You can switch enforcing smootly no problem mate
Just use selinux inverter or like this
You can don't like and don't use my rom but you cant fix me :fingers-crossed:
I see that some people don't respect my projects.
if they can do better than me, let's see.

Thank you

for random reboot problem use go mode
ro.config.lowram=true
add this line to build prop and reboot
thanks for your comments and feedback :fingers-crossed:

For some reason, i can't install it.
"Error 7" keeps popping up.
I was getting the same error when I tried to install other ROM, but it was easily solved by removing "asserts" and "getprop" lines in "updater-script" file.
But here, when i remove any of those lines or them both i get error 6.
Dunno what am i doing wrong or is it something to do with my phone.

Here's some info from recovery.log if needed: (error 7)
