improvement over cocore 8.8

Flashed over cocore 8.8 and xxlql combo.

Boot time is almost same.

Able to OC upto 1.228GHz with Perf guv and sio.

Benchmarks show significant improvement :

Antutu : 11088

Quadrant : 3963

Nenamark2 : 39.7Fps

No random reboots or FCs in 2 hours of use.

Used ondemand, ondemandQ and Performance guvs.

I/O is SIO. All worked fine.

Cannot comment on battery life as I use extended battery 3500mAh.(LOL..)

Anyway this version is slightly better and more stable than version 8.8

THANK YOU Cocafe...keep up the good work.

I use CoCore 9.0 two hours and I have a random reboot on any OC frequency.
[Galaxy S Advance I9070 Original Android Developmen] jagnik:
lots of random reboots after installing cocore 9.0...

tried all governors... but disappointed with all

[Galaxy S Advance I9070 Original Android Developmen] jb901:
CoCore 9.0 runs faster on my GT-I9070P, with no Overclocking. ANTUTU Benchmark with 8.6 = Score 8464 and with 9.0 = Score 9152, after use about 2 hours there are no Reboots, great.

I am from India. That extended battery cost me 1100 Indian Rupees. If you have ebay service in your country, search for 'I9070 battery' and look out for the 3500mAh Mugen Power battery.

Coming to charging it obviously takes longer time than standard 1500mAh battery.From 10% to 100% it took about 1 hour and all the while I was web browsing. Good Luck.:)

For all of you guys facing random reboots and FCs :

DO NOT use any governor other than Performance or Ondemand when you Overclock(more than 1GHz).

I use OndemandQ more often and other governors for brief period and I never faced random reboots.(CPU was @1GHz)

There seems to be a problem with cpu freq scaling and volt stepping when device is running higher than 1.05GHz.

Anyway as I suggest, use Performance/Ondemand governor when overclocking. Other governors can be used while running @ 1GHz or lower.

Good Luck. :)

Currently testing UV:

Freq Stock UV

200 1025 975

400 1050 1000

So far so good... Haven't tried going below these values for now.

[MENTION=4832589]cocafe[/MENTION], any ideas how far can we go before system becomes unstable?

I was planning to UV 1000 MHz to squeeze a bit more screen on time, in the mean time keep the OC frequencies unaltered for that extra kick.

[Galaxy S Advance I9070 Original Android Developmen] juanchotazo99:
Well, we're definitely faster in most areas than a stock (I presume) S2 now. And it definitely feels faster now. Magical cocore bits, yeah! That run was done with pegasusq/sioplus. and 1228 mhz. Thank you very much [MENTION=4832589]cocafe[/MENTION], you rock!

Now, a question. If I undervolt, do these settings stick after a reboot, or should I make, for example, an init.d script? Thanks.

EDIT: Nope, I rebooted and the settings were back to defaults. I'll keep experimenting to find the perfect voltage curve for my phone. Thanks again!
[Galaxy S Advance I9070 Original Android Developmen] nss357:
Still going good with the UV?
[Galaxy S Advance I9070 Original Android Developmen] krazzykid:

720p video playback support is entirely broken, even with a recorded 720p sample video ~ 20 MB from S Advance itself.

Audio is ok, but I can't pause it.. image remains static, while it should be dynamic, in movement. And once video is finished, it will freeze my phone.

I uploaded here:

No need to run it online, just offline.

I use ES Media Player bundled in Es File Explorer. All other videos in lower quality are reproduced without issues.

You must try MX Player, it is superb. I playedback 4 videos, 3 downloaded from internet and one recorder with i9070 camera.

I was very smooth. The downloaded videos were 1280X720 @ 25FPS, Video bitrate : 1.6Mbps, Audio : 192kbps.

I you still face issues with mx player, try S/W codec or try OCing your device.

After reboot UV value will back to default right?

So how do I make a script to UV so I don't have to repeatedly enter the command manually?

Like if I want to UV two step down, I just need to run the script twice
[Galaxy S Advance I9070 Original Android Developmen] isaak:
Thank you for suggesting Mx Player. However it seems that just changing governor from hotplug to pegasuq improved drastically my situation, except an isolated case in which this video presents distorted audio, like a robot voice but worse. While in another youtube application like "SuperTube Popup YouTube Player" it works ok, strange...
[Galaxy S Advance I9070 Original Android Developmen] krazzykid:
Yes, after reboot the voltage will revert to stock.

You can make a script by writing the following commands:

cd /sys/kernel/liveopp

echo set_volt=1 > arm_slot<id>

echo varm- > arm_slot<id>

Replace <id> with slot no. 0,1,2,3...

Repeat 3rd line of script for subsequent UV of a particular script. Save the script file with extension .sh

Example: under_volt.sh

To run the code navigate to the folder where the script file is present and run the following command.

su

sh under_volt.sh

Good luck!!

Mali OC

Now select the SOC0 clock source

Now select a maximum clock speed , e.g. 499MHz

Recommended maximum is 518MHz/500MHz. That's enough, 540MHz will FC benchmark or cause texture mapping errors.

[Galaxy S Advance I9070 Original Android Developmen] krazzykid:

IMO swelling occurs only due to quickly charging with higher currents. If I'm not wrong stock charging current is actually higher at 600 mA.

Current control does not seems to be enabled... So the current shouldn't be 900mA in this case but as in stock kernel, 600mA. The figures under [USR] should be " in force " if current control is enabled.

Taken while charging at the wall. Look at charger_data, isn't that 600mA for AC and 500mA for USB charging?

OTG support for this kernel

Did any of the below have changed?

( 6.2+) This can enable the internal vbus power supply for usb devices.

But the phone still cannot recognize our usb devices now.

We can use it for fun, like charging for other devices, USB fan...

Meaning did somebody manage to enable otg on this phone? So that the phone can read usb devices without having the need to connect to an external power supply?
[Galaxy S Advance I9070 Original Android Developmen] juanchotazo99:
Cocafe did some more research on the matter and concluded that our device doesn't support OTG.
[Galaxy S Advance I9070 Original Android Developmen] Pretorian187:
I would not be too sure about that anymore. I already checked a bit and I found this video: http://www.youtube.com/watch?v=A2ISZONo8KM This guy connects a USB mouse and a USB keyboard over a non externally powered usb hub to his galaxy s advance. And it works. I do not speak portuguese but he mentiones something about his kernel. The video has a crap quality but anyway.

I have the Samsung Galaxy Beam and it has the same Novathor U8500 chipset plus very similar specifications as the s advance. They are very close relatives so to speak ;) I am currently trying to enable OTG on my Beam, and I am wasting many hours for that. One reason why I did not loose hope is due to an os update for my phone. And that was the leaked 4.1.2 JB version. Now with that update Samsung added files and folders which were non existent on Gingerbread. Folders such as UsbA-F, they also added several USB mounting commands to vold.fstab and some other files. So OTG must be possible. Why else would they add these files and folders. But there is something missing to make otg work, and my current objective is to find out what. If anybody wants to join the quest ur welcome..:D
[Galaxy S Advance I9070 Original Android Developmen] shut_down:
You can ask that guy how he got it. :)
[Galaxy S Advance I9070 Original Android Developmen] Pretorian187:
I already asked him but I do not think he would reply. User Gdark just sent me a msg translating the video to english:

He said that he is 15 years old, and created this kernel with OTG support from scratch, and don't want to make it available because he will not have any credits from his "work" (???). He also said at the end of the video that he managed to enable TV out on S Advance, and said the kernel he "made" don't support pendrives yet, just show "OTG stopped working" message when he connect a pen drive on it

So from what I understood is that he wants more viewers for his video. Only then will he post the link with the kernel patches or files needed. But I dont care about that. I am onto something and I will let u Guys know once I get a better picture. We have a common goal it seems ;)
