-------------- v4.1 ------------------​

* viper4android is working in every app ! - like youtube , mxplayer , etc

* viper4aqndroid is preconfigured and works even after restart device ! - thanks for help tecknight

* fixed crashing Stock browser ( after closing last tab in browser was crashing itself until wiped browser data )

* fixed too fast completely dimming screen

* disabled more loggers in system

* If you have bios 2.02 possible boot to windows straitly via designated app - tecknight's work

* decreased wifi scanning from 180 from 90 - should be more stable now.

* switched kernel to permissive mode - earlier not all mods were working - now works everything.

* new tool for flashing v2 - FLASH_tool_Teclast_x98_air3g_and_2.bat

* also "special kernel for devices with touch problem I made designated kernel for my rom - boot_touch_fixed_for_mirek190_roms.img is on mega and google dvive

-------------- v4.2 ------------------​

* fixed mute icon

* new default wallpaper ;)

* Finally ! Fixed that stupid auto dimming on c9jx and c5jx devices !

IF YOU HAVE v4.1 THEN YOU DON'T HAVE TO MAKE CLEAN INSTALL .

JUST MAKE DIRTY FLASH IF YOU WISH .

IMPORTANT​

I recommend ( MUST ) wipe data ( not reffer to v4.1 ) because I changed a lots of things in virtual machine, apps and viper4android either will properly after you make data format.

I created xml file called flash-system_only_WIPE_DATA.xmll and tool FLASH_tool_Teclast_x98_air3g_and_2.bat for it !

Ps. I added new method of flashing like FLASH_tool_Teclast_x98_air3g_and_2.bat ( partitioning not working jet in this method ) now you have 2 ways of flashing :

- plug device via USB ( in android or droidboot ) and run script FLASH_tool_Teclast_x98_air3g_and_2.bat.

- or use MFT - intell manufacturing tool .
