Hey bro, Samsung Galaxy J1 mini (android 5.1) have same specs as our phone and even same chipset can we directly flash it on our phone? Or use it for building cm12 for our phone?
[Samsung Galaxy Core.] Nexxit99_Gaming:
But screen size isn't same j1 is 4.3 and core 2 4.5 inch
[Samsung Galaxy Core.] Ih24n:
Yes I know . I already see the kernel. I want to port TW from J1 MINI but I dont have whole the system firmware. I have system.img but cannot extracted. You can try by youre self if want to use to build cm12.
[Samsung Galaxy Core.] ItsMeShouko:
Can it be directly flashed without modifications?
[Samsung Galaxy Core.] Ih24n:
wifi error is my false in defconfig. the importan things is the kernel can fix temperature or not. If yes I will fix wifi and make kernel release version but if still cause hight temperature I will find another ways.
[Samsung Galaxy Core.] hammad97:
SIM is not working. When I open sim settings, it displays this thing Attention SIM card info not available. Menu cannot be accessed. :crying:
[Samsung Galaxy Core.] Ih24n:
If youre ask is "can flashed" I will answer "yes it can". but it will cause youre phone brick maybe can hardbrick.
[Samsung Galaxy Core.] Ih24n:
Try flash another formware first and install CM . Its modem problem.
[Samsung Galaxy Core.] Ih24n:
Scrren size is not important things. whats important is resolution of the screen or we call its DPI . Core 2 is 480x800(240dpi) CMIIW.
[Samsung Galaxy Core.] doesntexits:
Direct flashing other firmware may cause hard brick. For safety reason, don't do that
[Samsung Galaxy Core.] ItsMeShouko:
Okay if samsung becomes hard brick, odin mode can still be accessed right?
[Samsung Galaxy Core.] doesntexits:
"Hard brick" here means you can't even see your phone powering up, due to corrupted bootloader. Even Odin download mode can't be accessed

If you can get into Odin mode, that's "soft brick". You can still restore your phone to stock firmware and continue using it
[Samsung Galaxy Core.] hammad97:
I am already flashing it on stock firmware.
[Samsung Galaxy Core.] Ih24n:
[MENTION=5640594]kvsjxd[/MENTION] you need PORT if you want to use other firmware which have same specification . If not [MENTION=6586967]doesntexits[/MENTION] already explaint the effect If you not PORT it.

I see the kernel from J1 mini but very defferent with core 2.

Core 2 and J1 have very defferent block partitions.
[Samsung Galaxy Core.] Ih24n:
I says "another firmware" . Mean you must download again other firmware maybe you can use AOB1 for Asia version .
[Samsung Galaxy Core.] doesntexits:
Bro, j1minilte and kanas are almost having same specs btw. They both using Spreadtrum chips so, I think porting is easy, just by replacing libs and bins from /system folder. You can use stock kernel porting TW ROMs for sure, BUT NOT boot.img

Here I mean flashing stock firmware of others could cause hard brick, because you know, in our stock tar.md5, there's some binaries which contain boot parameters (bootloader) of the phone
[Samsung Galaxy Core.] I_your_thread_post_write:
I have tried this kernel. CPU Freq is frozen on value 1300 MHz and temperature is high.

I tested temperature for cm11 rom with different kernels (except stock rom) on the stress mode. This mode makes a high load for CPU and it is available in the Antutu Benchmark.

For Stock ROM I have seen the best results - 55 C in 15 minute of test. Cm11 since 23.04.16 has 68 C CPU in 4-5 minute test and the device was turned off. FIUI kernel has the same results.

The PAC man ROM kernel is little better, it can hold out more time (6-7 minutes), but the end is the same - the device is turned off before the completion of test.

All kernels have the same problem - sometimes the minimum CPU freq is freezing on the value 1200 Mhz and doesn't drop. It become normal only after reboot.

I hope my descriptions is clear.
[Samsung Galaxy Core.] Ih24n:
Are you have idea to extract the system.img from the firmware. I try many tutorial but nothing result. All tutorial work if use system.img from CM.PAC build but not for System.img from samsung firmware.
[Samsung Galaxy Core.] Ih24n:
[MENTION=6586967]doesntexits[/MENTION] Are you have idea or suggestion to fix this. Its kernel problem and I dont know how to fix its in kernel.:rolleyes:

First bro, where's your overclocked kernel tree?

Second, I think you shouldn't overclock this device. I've used my dad's Core Prime sometimes, and it's really hot near the camera while gaming (battery is still cool), where the CPU is on

Our regulator is highly broken. No SoC will use that much CPU voltage to raise CPU frequency. In my Galaxy V, it needs up to 1,35V for 1,4GHz, while others are below that value. If you overclock your phone with too high CPU voltage, overvolts may happen and your phone will reboot immediately during usage (of course if that not happen, your CPU will melt down for sure, probably the plastic case)

About this locked frequency thingy, tell people don't mention it here. Spreadtrum doesn't seems to be good at this. I'll tell later
[Samsung Galaxy Core.] ItsMeShouko:
We should not use overclock kernel for now. We should try to fix over heating problem and then overclock.

Also I can't choose mp3 file as my ringtone on CM11, PAC, FIUI roms... For using ringtone, I have to push the media file to /system/media/.../ and reboot, then I can use it...
[Samsung Galaxy Core.] dhiru1994:
How was the experience of using FIUI ROM i wants to try it any bug found in that rom please tell me more about that rom
[Samsung Galaxy Core.] ItsMeShouko:

[Samsung Galaxy Core.] Ih24n:
[MENTION=6586967]doesntexits[/MENTION] here the tree https://github.com/ih24n69/android_kernel_samsung_kanas .

In PAC i use standart kernel but it also have hot problem. And in CM it more hot . The problem is maybe CM requirepment much power which causing the clock speed still have high clock (stuck at higher clockspeed) Change governor not fix it. Only after reboot which can fix it. For easy usage like play mp3 in PAC rom(standart kernel) I only play 15minutes it have very hot teperature.
[Samsung Galaxy Core.] Ih24n:
Says thank you and hit thanks button :) .
[Samsung Galaxy Core.] Samuel2599:
Yeah, I agree. Over clocking the CPU might not be a good idea right now as it may fry or bake our CPUs..... Since the temperature is going over 60°C for a half an hour lite usage, for e.g, browsing the internet.........But still I must say that that phone in standby mode (Screen off) goes very well into deep sleep. And when kept in flight mode overnight, there is absolutely 0% battery drain (without Google apps and with a few apps installed), compared to the TW stock ROM which took about 20%-30% of the battery overnight in the same conditions........ So I just wanted to say that the CPU on this ROM performs well with the screen off, but stuck at 1200-1300 MHz with the screen on.
[Samsung Galaxy Core.] Azhero:
Does the current stable version have (2016-04-23) no issues in overheating? I'll try this on my sister's phone Galaxy Core 2 SM-G355H
[Samsung Galaxy Core.] Ih24n:
OK kernel tesst again and let me know overheat and wifi fix or not. I am try use SaberMod toolchain in this kernel.

Here the Link : https://www.androidfilehost.com/?fid=24572369242686042
[Samsung Galaxy Core.] (/|\Trunks/|\):
Bug/s I've seen so far...

- Every reboot, CPU sets to max 1300mhz with performance governor (getting stuck at max). Ignoring the set clock and "set in reboot". Need to manualy set sprdemand and clock tick everytime I reboot.

Fix...

- Wifi is fixed. I can test YouTube and other apps that randomly overheats and such. I'll test this for a day or two with sprdemand 500mhz-1200mhz without Kernel Auditor.
[Samsung Galaxy Core.] Ih24n:
OK I will wait the result. I hope the kernel can fix overheating/high temperatures.
[Samsung Galaxy Core.] RMYLOVE:
Every thing is running ok on my core 2 but, on status bar its shoving 2 sim and i cant access. In "setting" while i select "sim cards" a massage appears "sim card info not available menu cannot be accessed" what should i do. Please reply fast
[Samsung Galaxy Core.] AnDrOiiiD_YT:
Same thing. After some time min freq. stays at 1200Mhz
[Samsung Galaxy Core.] Ih24n:
The CPU freq is not an critical. Whats I know is the temperatures is still high or its can solve high temperatures or not...
[Samsung Galaxy Core.] AnDrOiiiD_YT:
Yes the phone gets hot. If the freq. stays always at maximum the phone gets hot. I always reboot my phone when it gets too hot, I dont want that my CPU burns :D
[Samsung Galaxy Core.] (/|\Trunks/|\):
After testing the kernel for a day, the temperature seems normal:good:. It won't just go 34°C or above (exept for heavy usage).

The only thing that needs to be fixed is the "Reboot = performance governor with 1200mhz-1300mhz" problem. Must be reset to normal every time I reboot. This can cause overheat if forgotten.

Small thing, sometimes when moderate-heavy usage the CPU ignores maximum tick when it wants to (Ex. The CPU ignores max 1200mhz then goes to 1300mhz) which is sometimes annoying for me. Hopefully this can be solved too.

[Samsung Galaxy Core.] I_your_thread_post_write:
If we believe the results of stress test then this kernel is little better than the PAC ROM kernel. On the load the CPU temperature increases slower. Possible, my test is not accurate.

The CPU frequency is frozen on 1200 Mhz.

I can test the kernel on everyday use.

[Samsung Galaxy Core.] AnDrOiiiD_YT:
I agree with [MENTION=7509465]I_your_thread_post_write[/MENTION], it freezes @ 1200Mhz but the CPU doesn't get too hot (stays at ~30°C, max. was 30.2°C). And what is working now is that we can turn off cores! :)

Thank you very much for your work!! Keep it up! ;)

Ok thanks for feedback. For what the kernel which you use its in youres.
[Samsung Galaxy Core.] AnDrOiiiD_YT:
Sorry I don't understand what you mean
[Samsung Galaxy Core.] Ih24n:
For what the best kernel its in youres. I build new kernel is for fix high temperatures so I remove underclock and overclock. And its will decrease benchmark but for performance its only little defferent with oc kernel.
[Samsung Galaxy Core.] Ih24n:
Wkwkwk nothing :D . so the new kernel its have cool temperatures? How about performace and ram uses?
[Samsung Galaxy Core.] AnDrOiiiD_YT:
The best kernel for me is that one (the newest). But it would be better if you can fix the problem with clocking. If the CPU stays everytime @ 1200Mhz it drains the battery very fast ;)

Edit: Performance good, RAM usage also. Temperature stays at 30Â°C not more
[Samsung Galaxy Core.] Ih24n:
For All I have some news . I done compile Spirit Rom and Mokee Rom. Any one interest with the both rom?

Hello to you and my very best wishes - you're really doing a great thing with this phone.

I'm right now testing the last kernel and will do that for a week or so - shall I get you some stress test results?)

Still, I would like to ask you for the advise - as far as I was a little bit in a hurry while updating system - I've lost my IMEIs and the damn EFS copy. Right now I managed to install someone else one, still - looking for the possibility to get my own id data back) So - maybe you know (according to your knowledge of this OS) - what's the best and most accurate way for the system to get them back? Octoplus won't let me do that unless I'll pay some $30+ for that and I actually haven't found another option which will really get my IMEIs back.

Thank you again for this whole thing - you're inspiring ^)

Yes kernel problem because if try use stock kernel which use cm ramdisk overheating not happen and cpu is controlable. Maybe you can try phoenix kernel in other post and lets see how it work..

I had some experiments for the stock ROM and the stock kernel without changes on the cm11 ROM (the temperature and the power consumption). For the stock kernel I got the same temperature results that with the native cm11 kernel. On the stock ROM the max CPU freq automatically dropped to 1000Mhz on the high temperature (about 50 C) that didn't allow the device to become very hot. But the device was heated over 60C on the long heavy load.

I hope this will be useful.
