did it work? I am struck on boot screen no matter what i do. And in installation instructions it says there is a "README" which is nowhere to be found
I found/had a really big bug today

i'm on the latest havoc 4.14 Version (vanilla) and needed to call an emergency number, i tried to call it a few times and the Aosp Dialer always gave me an Error while trying to call the ambulance, could anybody help me with that?
so i figured out but i dont get an in-call ui, i'm not using the Google dialer and i dont have it installed, could it be possible to add the in-call ui for emergency calls to the aosp dialer?

Hi. In the first mail of this thread I see install description :
2. Extract the zip and read the readme . (Basically you just run a .bat file ,.sh file etc depending on your choice os )
I downloaded and do not see any other zip. There are no readmi file. Where can I find a description how to install havoc ?

What is : Developer options -> Wakelock blocker ?
I know Boeffla wakelock blocker and understand it's sense.
Is someone who undestand havoc's wakelock blocker ? What is on the list ? It looks like predefined opportunities but not existed in the havoc (not all exist). Better, here are no real wakelock occured in the system.
How can we use it ? Is somewhere a document ?

If I activate smart charge in havoc, wakelock will be activated which kills possibility to go into deep sleep and eat battery all time. This wakelock is not possible to find and block in havoc's wake block. The only possibility is to use BBS or Franco Kernel Manager and repalce kernel for block the wakelock. If this is the only way, what is a sense of build-in wakelock blocker ?
Someone will say, this is not problem because if you activate smart charge it does not work correct and you will disable this option at once and you will not have to block it's wakelock ... True ... but why do smart charge and wakelock blocker exist in menu?
