Changelog v1.0

• Upstreamed to 4.9.178
• Some optimization for cortex a-53
• Set lz4 as default compressor for zram
• Set westwood as default tcp congestion control

- SELinux can run in two modes: enforcing or permissive (quite important, IMO).

or using TWRP.

[TureX]

Hi!
Can you write the exactly command that are you using?

Best regards

 

[jdpoveda35]

I've been using these two
fastboot flash kernel Phenix_kernel_.img
fastboot flash kernel "C:\Users\PC GAMER\Desktop\Nueva carpeta\Phenix_kernel_4.9.236.img"

 

[TureX]

I've been using these two
fastboot flash kernel Phenix_kernel_.img
fastboot flash kernel "C:\Users\PC GAMER\Desktop\Nueva carpeta\Phenix_kernel_4.9.236.img"

The second command is correct, try to update fastboot.exe

 

[jdpoveda35]

It still doesn't work for me, I update fastboot, I installed version 1.4.3 and nothing the same

 

[TureX]

I don't know , that's strange . Which variant of ane you have?( lx1 , lx3)
Have you got problems with the device?
Are you able to flash image like stock kernel or recovery_ramdisk?
