Reporting Bugs

• DO NOT Report bugs if you're running a custom kernel or you installed Xposed
• Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
• If it is a random reboot, grab /sys/fs/pstore/console-ramoops. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
• If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues.

Frequently Asked Questions:
Q)What phone variants are supported?
A)Mi Max with SD650 (hydrogen) is supported by me and NOT Mi Max SD652 (helium).
So helium users are not suggested to flash this.

Q)OH MY,.. CRASHES!?
A)This is a very early build of CyanogenMod running nougat and things are still WIP.
You may experience number of crashers here and there. These will be get fixed with time.

Q)Why did TheStrix made this UNOFFICIAL?
A)Because, we need our device to be bug free before enabling official CyanogenMod nightlies.

Q) Is VoLTE supported?
A) No. IMS seems to crash on N

Q) Where are Developer options?
A) Go to Settings > About phone, and press five times on Build number.

Q) How can I enable root access?
A) Go to Settings > Developer options > Root access, and enable it for apps, adb or both.

Q) I don't like superuser icon in statusbar, can I install SuperSU?
A) Yes, that would not show superuser icon in statusbar. This seems to break sensors on N, wait for update on this.

Q) How do I update GApps? (Also useful if you have GApps related problems).
A) Reboot to recovery. Wipe System, Cache and Dalvik Cache. Install ROM + GApps. (Yes, without rebooting). Reboot.

Sir please read FAQ.

Sir please read FAQ.

This I gotta try

TheStrix did incredible work on CM14 and a few related ROMs for the Redmi Note 3, I was using TheStrix's CM14 as a daily driver for a long time. Here's to a great CM14 for Hydrogen and Helium too.

Does this ROM work on CDMA carriers like China Telecom? I'm using the latest Hydrogen RR and it works fine on China Telecom using a UIM card and a few other overseas LTE/WCDMA/GSM carriers.

Thank you so much.

Welcome!

Great to see you starting development for Mi Max @TheStrix:good: One step closer to get CM official...
Now we will progress fast I am sure of it...

Don't know how aware are you of the custom roms development so far but allow me to point you to the most annoying and hard to fix bug we've had so far... the famous 3G data bug that some users in some countries with some service providers on some band frequencies suffer from. We fought this bug for a couple of months before I was able to find a workaround as I call it now. Then just recently with the great help of @The_Serial switching roms and providing radio logs(I don't have the bug) I managed to get to the root of the problem... See here for details...

I am eager to hear your respective opinion about this issue.
BTW I already have a test patch prepared for fix in Android telephony framework but can't build right now to test it... Let me know if you are interested...

Thank you for your work!

It's funny, but i don't have this problem on Nougat (this and karthik's). To be precise, the icon H dont showing, but 3G is works. On Marshmallow 3G still don't turns on.

Now I am a little confused
I am pretty sure @karthick mostwanted already implemented the working radio blobs in his vendor tree but then you should get H icon. Nougat acts differently!?
Don't know about what @TheStrix is using...

If that issue is not present in Nougat at all that's great... Just needs some small changes to recognize DC-HSPA+ networks as HSPA+ and we'll get icon back...

Can you post radio log from this release clean installed? See my signature for how to take it.

 

[The_Serial]

Ow! Great news!
I am ready to test and promise to be a good tester
Few minutes later I will answer about 3G

Of course.

Very good! Amazing! Best beta with a few problems like not working rotation and closing my poweramp...

 

[The_Serial]

Ho! 3G works. Without data have "H" letter and HSDPA, with data no letters and UMTS.
In information.
About bugs:
1 - even I use only one simcard in the second slot in notificatinon line and in settings them show me two simcards and number one I can not turn off. Reboots resolve it.
2 - in status bar I choose "circle" battery status style, but it shows standard icon.
3 - status bar menu in settings is not translated and many other settings are not translated, T9 is not translated
4 - flashlight does not work
5 - Settings -> System Profiles -> Settings ->Preferred network type = FC (logcat attached - settings.zip).

going on...

addon:
radio log on 3G is attached

Awesome first build apart from some bugs that will be fixed in time.

Fantastic work!

Will stay tuned!

Do not flash SuperSU or sensors will crash. (mentioned on faq as well)

OK, tbh, I still didn't get what 3G problem you guys are talking about. You are able to use 3G but don't see the icon in status bar? Something like that?

2,3 and 5: CyanogenMod bugs.
4: Camera is buggy on all devices with M blobs/libraries due to changes in camera driver in nougat.. Either we get N blobs or wait for some miracle guy to solve camera with M blobs fully. (scenario as of today)

 

[The_Serial]

You are able to use 3G but don't see the icon in status bar? Something like that?

yes, when have any data sending / receiving - no icon, when not have any data sending / receiving - icon "H".
But! Is it miracle? All other cm-based roms did not have an ability to work with "hspap" (for details contact nijel8, in post number 11 He started to explain and invite You to give full explanation of the 3G issue.
