Hi, I'm using this rom and everything seemed to be fine until I got an unexpected reboot and noticed that after this, my keyboard went back to the stock one and fleksy, which I had installed and set as my input app was disabled. Any way to fix this?

 

[GiolloAgus]

have a bug?

 

[burningcreation]

Anyone else using this yet? I might try it later on today.

I really liked this ROM but couldn't continue using it because I kept getting random reboots too.

Edit: I reinstalled and it's working well for now.

 

[lochstar]

Can anyone confirm if NFC is working in this ROM?

Using it.
Best OS yet for A20, as far as I know.
Ditching it though. Doesn't have a WORKING sim toolkit(Cc @Gabriel260BR). In Kenya you can't live without it because of mobile money.
Def coming back if it's fixed.

Edit: Found a workaround. Can use a USSD code #334#, so Havoc kaende sana

 

[Lordfrychicken]

Random reboots? Anyone know how to fix it?

 

[Tano_INA]

How to change the header image?

 

[KineSight]

How to change the header image?

What "header image" ?

 

[Slaggy]

Random reboots are usually because of the overclocked Kernel. Flashing another one can fix this issue.
It would've been better if we could see the list of bugs and weigh the pros and cons. I'll give it a try later tho.

Thats right. If you use Eureka Kernel. You should install V.5 first, because V.5 not set in 2.18Mhz. The default is 1.7Mhz. If you use V.7 directly without installing V.5 first, you might got bootloop because the default clock speed used in V.7 is 2.18Mhz.

Try to install v.5 first, then use HKTweaks to lower your Highest clock speed to 2.0Mhz or under, don't forget to set cpu governor to userspace to avoid changing after Flashing new Kernel. Then flash V.7, you won't found the bootloop again.
