Changelog old Versions in Post #2

This kernel is mainly based in hardcore work (thank you to Hardcore for his great contributions). I have added undervolting (kind of phenomenal) and some additional features.

- CWM and TWRP recovery in Samsung. In AOSP I will use only TWRP in the future.
- No logs, no extra debugging
- install su, supersu in samsung. Support init.d and cifs
- Ondemand Tweaked by Hardcore
- Added some governors (specially tweaked slp and zzmoove)
- Scheduler changing enabled
- BLN enable (Since Apolo 4.5 BLNWW too)
- CRT-OFF enable
- Effective Underclock (max frequency limited)
- UV Interface for ARM (you can change voltages in ARM with external aplications)
- Kernel Includes frandom for using with CrossBreeder (I really recomend it, Thx idcrisis)
- No Overclock and no different CPU-GPU steps from stock (please don't ask me more about that, I won't add it)

Update Supersu (only sammy kernel, AOSP doesn't have supersu)
Choose normal update (not the other with CWM/TWRP). In case you chose the wrong option, you'll have a bootloop. Read the bootloop section in this OP to recover your system.

UV cannot damage your mobile phone, but it can make your device unsteady. It is important that you choose the right version for your mobile.
There are some Apolo versions depending on the UV used:

- Light (stock voltages)
- Regular (-50mV in ARM, internals)
- Extreme (3 versions, you can try to see what versión is better for your battery life): in JB system chooses among the different steps available inside the kernel (in internal and ARM), so depending what step is chosen, final voltages applied are different.

Regular and extreme has -50mv UV in GPU (others UV like bus, memory, video controller too). Light has stock voltages in GPU

I recommend you try regular version first. If there are no problems in two days (reboots or frozen screens) you can try extreme V0.

System changes voltages in some devices (new in JB). Android chooses among voltages included in kernel (8 steps in every frequency). I recommend not to change them in extrem versions.

More information and Voltages values:

Depending on the device, system changes voltages (in JB), choosing among voltages defined in the kernel source. It seems, system tries to choose the ideal ones for every device (taking into consideration internal and ARM voltages).

For each frequency, there are 8 posible voltages in the code (I call them steps). In ICS, system always chose 4th step for every frequency, but in JB it doesn't sometimes.
It happends with ARM voltages (you can see them in the configurator) and with internal voltages, so there are many possibilities

You can see ARM and Internal voltages in this pdf (it is in Spanish but I think you can understand it) :

So, it is not strange that configurator shows different values in two different devices with the same Apolo version. It simple, system has chosen different voltages steps. I recommend you don't pay too much attention to this, it is not important, indeed system try to be stable choosing different values.


- TWRP and CWM Backups are not compatibles between them, so you need the suitable version to restore your backups.
- I recommend OBackup. Great application for making backups in Android itself (it supports TWRP and CWM).
- Not always less voltages means better battery life, it depends on your device. The only way is testing every version and please start with Regular or Light version
- Deep Sleep problems sometimes is caused by undervolting. If your system doesn't enter in deep sleep and it is not because of any application , install regular or light version.
- It is not the same, lower ARM voltages with an external APP (for example Apolo Configurator) and change Apolo version (V2,V1,V0 or regular) because there are more voltajes involved (not only ARM)
- If you want to turn off the leds always (when you touch tactile buttons), you have to use Apolo Configurator, otherwise (if you use only Samsung settings) your leds will turn on when you turn on the screen.
- If your system doesn't boot due to wrong Voltages, flash this in recovery : download zip
- Acess to internal sd in TWRP recovery :
(Up a level )
then go to
that's your internal sd

- Recommended wipe Cache and Dalvik after changing any kernel (it is not mandatory but it is a good custom)
- To increase sound volume use mods like Viper or appications like Alsa Mixer or Vodoo louder in play store

Enable logs in TWRP and v7 : Create a file in "/data" named ".enable_logs" and reboot.

¿In kit kat, should I use CM version or Omni version?
Just see if your ROM has superuser included (I mean if you can gain root just enabling it in developer options). In that case you should use CM version. If your ROM needs supersu to manage the root, install omni version.

- Battery Animation doesn't work when phoes is off

- S2W doesn't work after rebooting.
It's because this S2W bug: "When the phone is booting, if the screen is off in the exactly moment the script is changing the S2W setting, the screen will not respond any longer and you have to reboot."
To avoid it, increase the screen timeout. Another solution is to keep the screen on, while the phone is starting until android had started completely and you can be sure that the script has been applied (more than a minute because the script has 60 seconds of delay).

- If BLN y/o WIFI doesn't work in kit kat ROMS (maybe it can help in other bases too)

If test button works in Apolo Configurator check if in your Android Settings- Display there's something related to notifications led or Notifications light
or review
Rom settings (name depends on the ROM) - Active display must be disabled, otherwise BLN won´t work

If BLN test or wifi doesn't work, try this:
- Remove Apolo folder in /system (if folder exists)
- Go to Recovery
- Wipe Cache
- Flash Apolo
- Wipe cache again
- Reboot

- Avast doesn't work with Apolo, if you can't live without it, use other kernel, sorry

- Bootloops: it doesn't happend very often but it can happend in JB if there is something corrupt in partitions. Posible solutions:
1) Try to enter to recovery. Press vol up, Home button and Power button at the same time until the device enters into recovery (system can restart 2 or 3 times, but don't release buttons). Then wipe cache and dalvik and reboot.
2a) if 1) didn't work, enter into download mode and flash light TWRP version if you had CWM. Wipe cache and Dalvik and reinstall CWM if you wish.
2b) if TWRP didn't work or you had TWRP version already, flash last PhilZ kernel (thx to Phil3759), enter into Philz recovery and wipe cache and Dalvik. Then reinstall Apolo.
3) if nothing worked, try to reinstall your ROM without wipe data and wipe cache and Dalvik
4) wipe data (you will loose all your application and configurations)
5) reinstall with odin stock ROM WITH repartition (pit file). Then install Apolo and reinstall your custom ROM.

- Sometimes when you reboot your device, your battery seems to drop a lot (it is not real).
To recover your old battery percentage, plug in your device and reboot into recovery. Check your battery level in the recovery, if it is correct, reboot (solved).
If it is not, reboot into recovery again (in CWM advanced - reboot into recovery, in TWRP reboot - recovery). It should be solved.
This issue never happens if you reboot your device while is charging, so I recommend you plug in your device before rebooting (if you can do it)
If you can't plug in your device, don't reboot if you can avoid it

- AOSP: Recommended installation procedure for 4.3 ROMS (stuck in the second boot) Read post 3

- AOSP: Restoring backups changing ROM base (stuck in the second reboot), Read post 3

Download Kernel


Installation (you can install Apolo through CWM or TWRP recovery, it doesn't matter)
- Use a kernel cleaning script before installing (for instance Gs2KernelWipe thanks to hawkerpaul, but you can use other)
- .zip : install in custom recovery
- .tar : install in PC with odin (windows) or heimdall (linux)

Apolo Configurator (Available in Google Play again HERE)

I've developed a multilanguage application (Spanish, English, Italian, Catalan, Gallego, Russian and Turkish).You can change governor and scheduler, set ARM undervolting, configure BLN, BLNWW and S2W and set brightness curve:

I extremely recommend you read the Apolo Configurator Manual : Apolo Configurator Manual

My recommendation about scheduler/governor (it's only my opinion, maybe yours can be different)
- You can find 3 defined profiles in Apolo Configurator (performance, balanced and battery saving) based in noop/slp. I have changed parameters to achive the profile goals.
- Another good combination is noop/zzmoove

- Hardcore for his fabulous kernel speedmod
- Thx to great Phil3759 (he helped me to build the CWM recovery and let me use his recovery in the new Apolo versions) Please, visit his great job here
- Thx to jeboo for his great kernel and for let me use his TWRP recovery
- Thx gokhanmoral , great master. Most advanced features come from him
- Thx dorimanx for his great kernel and sources

INSTALLATION PROCEDURE FOR 4.3 / WIPING DATA ( if you are going to wipe data, skip 4,5 and 6)

In 4.4 is not necessary if you are using beta2,beta2b or beta3 (Omni or CM)

I don't know what the problem is (update: the problem is recovery) but if you follow this procedure (fresh install) you won't have any problem. If you install the rom right with Apolo, you may be stuck in the second reboot ?¿?¿

1- Install CM recovery (it is better install ROM with CM recovery). You can download it here
2- Advanced - Reboot in recovery (you will reboot in CM recovery , it is no a touch recovery, sorry)
3- Wipe data (and format system if you are going to install a new ROM)
4- Install ROM
5- Install gapps
6- Wipe data again
7- Boot system
7- Do the initial guided setup (wifi, gmail, etc) and install a couple of your apps
8- Reboot (it takes to boot a little longer than usual, even a couple of minutes)
9- After a successful second reboot, you can change the kernel to Apolo and you won't have any issue. It will always boot normally.

RESTORE ROMS IN AOSP ROMS (moving from 4.3 to 4.4 or from 4.4 to 4.3)

This issue only happends (AFAIK) when you change your base restoring the backup, for instance if you are in 4.4 and restoring a 4.3.1 backup. In my experience if you are in the same base, it works right.

You won't have any issue restoring roms in firs reboot, but you may be suffered the same issue (stuck in samsung logo) in second reboot, after restoring your backup. You can do your backups with Apolo, the issue is restoring, but I recommend you do your backups with OBackup App, because you don't need to reboot in recovery (you can do it in Android without rebooting)

If you want to restore your backups successfully I recommend you first change the kernel to CM kernel and then restore your backup:


1- Reboot in recovery
2- Install CM recovery download
3- Advanced- Reboot in recovery
4- In CM recovery : Restore your backup
5- Reboot and everything will be fine

No plans , too much work translating and maintaining two CWM recoverys, but I wouldn't mind to include any English CWM recovery if somebody let me use it (as I did with TWRP from Jeboo)
