thanks.. its work
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] kvern:
Thanks a lot for this, seems to go to be true.

Is there any cons to perform this ? like Battery draining much more faster or unstability of the system ?
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] mLawrenci:
Any downfalls?

Thanks a lot for this.

One question though. Are there any downfalls? Even though we could always go back to stock, would be good to know if activating 4 additional cores that were previously inactive has any effect on the phone. Like why are they even inactive in the first place?

:good:
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] qwsdert4:
no discernible performance gain. cpu-z always show the last 4 cores as "stopped".
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] ashyx:
Have you tried loading the cpu's with something intensive?
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] qwsdert4:
I will try, since sliding the screen would not put any hard burden on the cpu.

I suspect that the custom kernel only unlock 1.6GHz and also reveals the true name of the CPU. However the other four cores are still locked by some means. It would be great if the other four cores are unlocked, since it is such a beautiful little handset
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] qwsdert4:
confirmed, working (by ticking all cores in Kernel Adiutor home page). God this phone is fast now! Thank you very much OP

OP please delete this post #16, I dubled it.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] fook42:
yes.. you dont need the custom-recovery like TWRP or CWM... it's only necessary for backing up your device before you flash the new boot.img
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] Aceseatleon:
Info

After flushing will it be like factory reset or all of my data will be in my phone?

Why did you mentioned that custom recovery is needed for backup (for what) or it is must to backup the phone i case something to go wrong?
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] Noryakky:
U need custom recovery for backup boot sector, just in case when something goes wrong with flashing that boot
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] Aceseatleon:
What about the data. Reset or everything will stay intact.?

[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] Aceseatleon:
Could you please make a video of how to do it. I (probably We) don't know how to do it. Should i extract the file or not or where to put it and how in odin.

Another thing is that nobody explain is there any problems after installing the mode even is already asked in treads before.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] Noryakky:
I will try to make video or text tutorial, maybe today or tommorow.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] Noryakky:
Ok here you have guys a tutorial (

You doing it at your own responsibility!

)

0. Sorry for my english, I'm trying to do my best.

1. I made root and custom recovery using this tutorial: http://xdaforums.com/samsung-a-series/general/twrp-3-0-0-galaxy-a3-2016-sm-a310-t3316176

2.

CHARGE YOUR PHONE TO MIN. 80% FOR SAFETY!

When you have freshly installed root and custom recovery TWRP , boot to it and

BACKUP YOUR CURRENT BOOT SECTOR

---> PIC 1, then 2 ---> swipe to backup.

2a. (For safety, I

strongly

recommend to backup ALL of your partitions(excluding cache partition, nothing important there) - TICK: Boot, Data, System, EFS, and Modem)

3. When you done backing up your boot sector, next - reboot to 'download mode' (using TWRP---> PIC 3, then 4) and leave your phone on the desk.

4. Download 3rd link from 1st post in this topic and

EXTRACT IT FIRST

, then run odin app via administrator rights (right click on the Odin3 v3.10.7.exe --> Run as administrator), click on the 'BL' button, then look for a "boot_sm-a310f_8cores_1600mhz_rooted_by_sekil.tar.md5", wait 5-10 secs (odin1.png), plug your phone in 'download mode' to your PC,

wait for rectangle change color to light blue and all drivers is installed

- just wait 2-3 mins, I think it's enough for Windows to install all drivers needed(odin2.png), then click 'START' button.

5. Just wait, untill your device boot into android, then unplug the cable, reboot to recovery, wipe cache and dalvik. (not sure if neccesary, I did it)

6. Done.

EDIT:

ashyx says: In reality it's supposed to be flashed via the AP slot. It just happens that it also flashes via the BL(Bootloader) slot.

I don't actually know if it's true or not, but keep it in mind guys. I've flashed via BL and it's worked for me, twice.

If you see any mistakes or typos, feel free to correct me.

If you have questions, ask me here in this topic, I'll try to help you.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] ledocta:

looks good!

first show all 8x cores, but they stop working after a minute.

then i did a reboot, now showing all 8x cores workin on 1200MHz.

but goes back to "stopped working" on CPU-Z

want to upload a picture, but since its my first post, the board doesnt allow me to...

I wrote u back [MENTION=7411160]ledocta[/MENTION] on PM about 4 cores :) Next time try to post here on forum, more people can see it :p

Here's Our PM's:

Geekbench when I manually set up 8 cores to 1,6ghz (I can't add image to previous post, so I placing it here)

BTW: I noticed that the interactive governor for (extra 4)BIG cores turning them off after some amount of time, coz (I suppose) system doesn't using them all the time, so this is energy saving in interactive governor or smth like this.

I flashed the boot.img to an SM-A310M, it works but the Activities and Back button are not working anymore.

I have reset the cache partition and the dalvik cache, but both buttons still aren't working. Any ideas about how to get them back?

Benchmark test, active CPU number, etc are working as intended though.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] Noryakky:
Hey,

I am sorry to hear that, maybe try to flash a original kernel again, or entire original ROM for working touch buttons.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] rtrigo:
SM-A310M

Thank you!

I have already done so, just using Kies, because I already tried all kinds of resets and cleanups and it didn't help.

So is it because the kernel? Nothing else like a configuration file? I'm asking this because I don't know what a boot.img contains.

I want to try again when I have time and disable first everything Knox I can using Titanium Backup.

[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] jefke2:
No problem with battery life whatsoever, 4 out of 8 cores are disabled when the extra CPU power is not required, the 4 remaining active cores go down to 400 MHz.

SM-A310M

I tried this on an SM-A310M and it worked but the capacitive touch buttons, for Recent Apps and Back stopped working.

Would it be possible to make this work on the xxxM models? the capacitive buttons not working with this kernel mean something? like I did something wrong in the process or is it a sign that the kernel is not fully compatible with the M series hardware?

[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] m3mmo:
Well, can author of this post please explain to us how is it possible to unlock cpu to have 8 cores while it is not even 8 core cpu!??As I recall a3 2016 has Exynos 7578(which is 4 core cpu) and not 7580(8 core cpu)???A5 2016 has an octa core cpu so...this looks to easy m8.Can anybody actually record a video of their a3 6 phone so it can be really confirmed.Pictures are to easy to manipulate.

EDIT: I was little curious so I installed cpu-z and actually, it indeed says that it is exynos 7580 inside my phone!!??WTF?How is this even possible??
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] lawliet80:
Probably some eco during production or doing it in order to get a better battery life (even though the last 4 cpu auto-shutdown if they are not necessary). Odd story

In any case, it is good to know that we can unlock our phone and i hope devs will automatically unlock the processor in their next builds (cm13 :) )
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] ashyx:
Well it's dubious anyway. Still no source code link.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] jefke2:
Samsung probably disabled 4 cores to have a reason to bring the A5 (2016) to market. Maybe the OP just took the kernel from an A5 (2016) image ? Could someone verify this ?

Anyway, attached is an image from Antutu on the SM-A510F (A5 2016) with a score of 41568, next is the actual score of my own phone, 41567 ! This proves that the eigth cores are working.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] ashyx:
Samsung haven't disabled anything, it's an Exynos 7580 octa which uses big. little architecture.

All 8 cores are active just not at the same time

Take the specs of various websites with a pinch of salt. The all use the same (incorrect) source for info.

I won 4.5K on Antutu, which gives a lot of importance to gpu perf.

So I think it is rather good. I did not see any downsize with battery as the second clusters( the part of the cpu having the extra four cores) is enabled only under "mid-huge" load operations

[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] ashyx:
In reality it's supposed to be flashed via the AP slot. It just happens that it also flashes via the BL(Bootloader) slot.
[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] ockiller:
I noticed that it also unlock two frequency steps for the GPU. With the stock ROM it can go up to 668 MHz. With the hack it runs at 800 MHz (with the 734 MHz step also unlocked). So the GPU gets also a nice boost :)

On the bad news, I could see that on some heavy loads the Exynos 7578 (4 cores @ 1.5 GHz and GPU @ 668 MHz ) can already throttle (juste a couple of minutes of gameplay in Unkilled for example), so there is far more throttling when the hack is applyied (3DMark, Antutu 3D, any kind of heavy 3D load). It's harder to find a scenario where we can consistently load all of the 8 cores so it's harder to have throttling with a "CPU intensive" load (but definitely possible : Stability Test + Antutu stress test make it throttle hard).

If you want to experiment by youself, you can use Cool Tool to display in a small overlay that fit in the status bar some useful infos such as CPU utilization and frequency (100% = all cores at 100%, and frequency is only frequency of one island of cores). To get GPU utilization, frequency and SoC temperatures, you have to use custom labels and get those infos here :

GPU frequency: /sys/devices/11400000.mali/clock

GPU utilization: /sys/devices/11400000.mali/utilization

Temperature*: /sys/class/thermal/thermal_zone0/temp

*there is several thermal_zone available. The '0' is the first CPU cores island (always there). The '1' is the GPU if you haven't unlocked the second CPU cores island, otherwise it is the second CPU cores island, and the GPU is at thermal_zone2.

Happy hacking ! ;)

[Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot] ashyx:
You are very misinformed.

The kernel is contained in the zImage which is part of the BOOT.IMG along with the ramdisk.

The BOOTLOADER is a completely different binary and located on an entirely different area on the device.

The two are NOT the same.

The bootloader is a piece of low level code unique to the device which executes before any other software including the kernel. It's responsible for initializating the hardware on a device.

Without it the device would not even turn on.

Once the bootloader initializes the device it THEN boots the kernel

The recovery.img is also a separate binary and is NOT contained in the bootloader either. Nor does it contain the MODEM which again is separate.

You obviously incorrectly assume that the ODIN flashable BL tar archive from the stock firmware is actually the bootloader itself.

I suggest you educate yourself and do some research.

I tried it out on my own now and this is my experience/opinion:

After installation and first reboot all looked very well. Statistic apps showed all 8 cores running - of course with shutdown after a few minutes - but working.

Some minutes later my device stopped reacting to any inputs.

It then stopped working completely. I wasn't able to restart the device. Any try to boot the device wasn't successfull at all. Just a black screen.

After many failed attempts I was successfull with booting in TWRP to restore my old boot kernel. All working fine again...

BE CAREFUL WITH THIS MOD!

Until the sourcecode isn'r released, I would not trust this guy...

If your bootloader is unlocked, as mentioned in your other thread, download a stock image from Google and flash its components (except userdata.img) using ADB. As a result of your tinkering, something got messed up on the device, and flashing the stock image should resolve that.
