Debugging
/proc/kmsg is a file that stores all the kernel messages from the very first seconds of the boot process. A copy of that file isn't always needed to fix a bug, but since I've explained how to get one I don't even remember how many times, I'll write here the needed steps:
1. open a terminal on your phone
2. run the following commands:
Code:
su
dmesg > /sdcard/helium.log
3. the log will be stored in helium.log.
If the issue caused a reboot, step number 2 changes:
Code:
su
cp /proc/last_kmsg /sdcard/helium.log

Reserved
init.d script editing - not required as of v46
Important: your modifications to the script will be lost:
  • when you update the ROM, if you use an AOSP-based ROM;
  • never (changes are persistent), if you use a CM-based ROM.

the init.d script provided with the kernel (01helium) contains some lines that enable or disable certain features. Remember that the script is written in shell language, so the lines starting with # are ignored.
In the script you'll find useful tips to edit it correctly.

What goes wrong? At which point does the phone get stuck? I also got a booting problem once today, after the SONY logo I got a black screen and then the SONY logo again, but after a few seconds the phone booted. So wait a few minutes before stating that the phone doesn't boot and tell me what do you see.

On CM12.1 Official 20151116 with Helium v1 I can't use toggle buton to see my last used apps
With T10.2 this working.
I don't know how but this is strange.
