HELP & FAQ


"SYNAPSE BOOT CANCELLED"

 
  1. Wait for the kernel to stabilize and device to cool
  2. Open synapse app
  3. Synapse app menu > select all globally > undo > apply ✔
  4. Re-boot
  5. If still issues > try again after #1
  6. Still issues > Manually set config after boot (open synapse app > syanapse app menu > settings > disable apply on boot)


ISSUES

 
  1. Uninstall any CPU control apps, tweaks and scripts etc.
  2. Uninstall your current busybox with https://play.google.com/store/apps/d....busybox&hl=en
  3. Flash kernel
  4. Boot and allow things to stabilize
  5. Open Synapse & tap :
    1. "understood" message about unstable boot
    2. "select all globally"
    3. "undo" button
    4. "apply" ✔
  6. Reboot and ensure "synapse boot completed" toast message
  7. You should be good to go


BOOT-LOOP

 
  1. Power off & let device cool
  2. Wipe cache & dalvik-cache in recovery (if custom recovery)
  3. Re-flash kernel
  4. Re-boot
  5. Let things stabilize and cool before touching anything


WILL YOU BUILD FOR MY SM-T8xx DEVICE or VARIANT

 
  1. Not supported
  2. I will only build using the latest official T700/705 Exynos (international) source fully compatible for my own device


WHAT ARE THE "BEST" SETTINGS FOR BATTERY LIFE

 
  1. There are no best settings. User "habit" is #1 cause of battery drain, followed by screen, ROM & apps, modem etc
  2. This kernel is built to be balanced with a good mix of battery whilst keeping performance
  • Decrease screen brightness
  • Use dark wallpapers and app themes
  • Check your wakelocks with better battery stats app & use Greenify app to stop unwanted apps self starting and running in the background


CAN I USE OTHER KERNEL CONTROL APPS

 
  • No, many features and options won't be available. Remove all other control apps to avoid conflicts !
  • Synapse is the recommended and has everything you need


LITTLE CORE CPU FREQUENCY

 
  • Real frequency is apparently double that reported by other apps
  • Example: min 200 MHz (real) in Synapse is reported as 100 MHz in SetCPU


RANDOM REBOOT

 
  1. Don't UV or UC CPU or GPU
  2. Use SkyHigh defaults


DOWNLOAD LINK NOT WORKING

 
  1. I want to keep this project all in one place (Thanks to XDA) - ☆☆ NO MIRRORS ☆☆
  2. Please try again in a few minutes


POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE

 
  1. Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
  2. HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE


BACKUP & RESTORE

 
  1. If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
  2. Reboot after applying your new settings
  3. Read "ISSUES" & "SYNAPSE BOOT CANCELLED" above


TCP/IP NETWORK SECURITY

 

* Thanks to zeppelinrox & V6SuperCharger
  1. Hardening the TCP/IP stack to SYN attack
  2. Bump up tw_buckets in case we get DoS'd
  3. Ignore pings
  4. Don't cache connection metrics from previous connection
  5. Don't pass traffic between networks or act as a router
  6. Enable spoofing protection (turn on reverse packet filtering)
  7. Don't accept source routing
  8. Don't accept redirects

SEGMENTATION FAULT

 
  1. I don't believe it's kernel related, but rather busybox
  2. Try uninstall your ROM busybox with this app. https://play.google.com/store/apps/d...ricson.busybox and reboot.
  3. Re-flash kernel
  4. Use the busybox that comes with the kernel located in /sbin
  5. Also try to update your SuperSu and su binary if it asks and reboot.
