Announcement from Crostantin: Simple. Fast. Stable and Linear

Hello guys! We present LinearBoost! Based on Lollipop, fast and.. Linear!.

This project starts with the collaboration between me and hottix. . The baseline is create a fast and stable ROM built from the source. All the features are added for improve the android experience without compromising speed and stability. The kernel is the fantastic Linear, created by Hottix for this ROM, based on the google kernel ! During the way CriGio became part of the team as the official themer. We hope you like our work.

**** Disclamer ****
Your warranty is now void. I am not responsible for any damaging your device or alarm clock which will not come off. If you decide to flash my ROM, you are getting responsible yourself. matter how much it cries, don’t flash its after midnight, don’t get its wet and at last, absolutely don’t expose its to sunlight... Have a functioning Nandroid in case something goes wrong.

-A lots of optimization
- Navigation bar height
- Battery Percentage
- Volume Rocker
- Delete Screenshot and block screenshot sound
- Kill app by longpress back
- Advanced Power Menu
- Quick Pullwown right side
- Dialer Lookup
- Double tap to sleep
- Vibrate on call
- Clear all recents

First Installation
* factory reset
* flash last linearboost zip
* flash gapps
* reboot

Ota Updates
* flash last linearboost zip
* reboot


If you like our work,please feel free to donate ^_^

Where is the Linear kenel zip?
No is released on xda
How works OTA updates?
The rom has a solid backup system. We use the backuptools function and gapps are temporary saved and restored during the flash. If you want to change Gapps you need to wipe (or format) /system before flashing the ROM. In addition: SuperSU is integrated in the zip and we added a script for preserve the linear kernel configuration during the flash. If you already have used Linearboost and you have a custom kernel configuration, the zip will restore it from sdcard (don't wipe all your data).
Can you split the kernel?
No, we can't. Linear is the engine of the rom. Feel free to flash what you prefer, remember to delete 99linear in /system/etc/init.d before.
What about request?
Request will be ignored. Is the new way....

LINEAR CONFIGURATION (for Linear kernel):

You can change many parameters with this configuration file located in /etc/linear.conf without using 3rd party applications.
Use a file manager with root permissions, making sure you have permission to read/write and the latest version of busybox.

Note - Applications such as trickster there may be conflicts... use script or app, otherwise any post reporting issue will be ignored. This kernel has mpdecision stock, a touch of boost frequency 1267 MHz, this frequency will be displayed as a minimum in applications such as trickster mod. Minimum frequency is 300 MHz.
If you want to use faux sound app download this zip to remove sound script in 99linear and to avoid conflicts.

After edit linear.conf to apply changes there're 3 methods available:
1 - reboot device
2 - install a file manager with run script feature as root browser, go to directory /etc/init.d and open (as a script) 99linear.
3 - Android terminal emulator and type these commands:
To verify configuration options open log file in /data/local/tmp/linear.log


CPU Governor
i/o Scheduler
Readahead Buffer Size
TCP congestion
Sweep2wake Sweep2sleep - 0 to disable sweep2wake / 1 to enable sweep2wake and sweep2sleep / 2 to enable sweep2sleep only
Doubletap2Wake - 0 to disable doubletap2wake / 1 to enable doubletap2wake bottom / 2 to enabled doubletap2wake fullscreen
Power Key Toggles S2W/DT2W - 1 to disable s2w and dt2w with the power button turning the screen off
S2W/DT2W Timeout - enter number of minutes to automatically disable Doubletap2wake and sweep2wake
Fastcharge - 0 off / 1 on
GPU Governor - ondemand/simple/performance
GPU MAX freq
Color Profile - 44 profiles
Backlight dimmer - 0 off / 1 on - minimum brightness lower than stock
Sound profile - 5 profiles
