As I have all backups made with cwm recovery, when the latest version is installed and if by any chance anything goes wrong I would not have a recoverable backup. So I would like to know if I can replace the kernel.bin from twrp Recovery flash file with the kernel.bin file from version r16 to get cwm recovery and sign it with zip signer. I would be able to cwm in twrp to restore backup.

You can have a try.

If Something goes wrong, you can make a tarball and flash cwm kernel by Odin

Hi guys, on the OP says this kernel requires Samsung GT-I9070 (Android 4.1 Samsung Stock Firmware). Is this still true? I want to install TWRP but I'm on Android KK 4.4.4... How can I do?
[Galaxy S Advance I9070 Original Android Developmen] Sami Kabir:
Nothing has changed. This kernel will only work on Samsung's 4.1 firmware (and ROMs based on it). Because all other AOSP based ROMs come with CWM - the only "easy" way to use TWRP (at least on this phone) would be by using a custom kernel for our phone that is compatible with AOSP based ROMs and also has TWRP instead of CWM.

I asked the creator of MK Kernel to consider building a kernel with TWRP recovery but he said that he doesn't intend to do it any time soon.

I did not know that! Wow. Thanks for sharing this info! :)

My plan is to buy google pixel 2 after six months from the release... especially for development reason, because I'm studying Java for Android and a google rom without bloatware would be perfect. Until then, I'll keep using this phone.

With the right apps you can still live with it at a decent speed and the next Android O will support a special mode for all devices with less than 1 GB called "Android Go". I would be curious to see how it could be for an old device like this.

If you are not using it, my suggestion is to send it to an experienced developer that could do the job. A sleep phone is a non-sense if you have more recent devices that you can use at any time.

Q1. which kernel i should go for cocore E4.4 cwm or cocore E4.4 twrp or other versions??

Q2. since i dont know much so on reading about other peoples post here i decided to manually flash CoCoreE4.4(CWM)..saw a big difference in more smooth ui and better performance than stock kernel..big thanks to CoCafe and dev's.. but im facing some difficulties..whenever i write those commands in Terminal Emulator app mentioned on 1st page by the developer i get a message like permission denied everytime.. HOW DO I SOLVE THIS..??

Q3. im not able to create init.d folder in system/etc through ES File Explorer..it says "operation failed"

Q4. which termal app i should use?? is Android Terminal Emulator app fine https://play.google.com/store/apps/...1bGwsMSwxLDMsImphY2twYWwuYW5kcm9pZHRlcm0iXQ.. i have installed busybox as it was recommended above but dont know how to use it or for what purpose its used??

I HOPE YOU ALL WILL HELP ME IN THIS..please..asap..!!
[Galaxy S Advance I9070 Original Android Developmen] adamuadamu:
q2: first execute command "su" to get superuser permissions

q3: go into ES' options and under root options check to mount system rw

q4: every terminal app should be ok. busybox is needed for some advanced operations - ie. it's good to have it in the system for tweaks like v6 supercharger, but most probably you won't be using it directly

[Galaxy S Advance I9070 Original Android Developmen] RSDamasceno:
Dear,

cocafe

.

First I want to congratulate you for the excellent work done in their various kernels.

And I wanted to also explain what happens to me.

Here we go:

I use an app called CallRecoder (skvalex), it is very important to me (and before you say that - in some countries - is illegal: where I live, recording calls is permitted provided that the caller warned. Which I do.) .

I did several tests with various settings in the application, combined with several versions of your kernel (and other kernels).

Below I made a list of kernel versions I tested and what the results were:

Stock kernel (LQ4) = [COLOR="Lime"][B]OK[/B][/COLOR]
Cocore-e 2.8 = [COLOR="Lime"][B]OK[/B][/COLOR]
Cocore-e 2.9 = [COLOR="Lime"][B]OK[/B][/COLOR]
Cocore-e 3.3 = [COLOR="Lime"][B]OK[/B][/COLOR]
Cocore-e 3.9 = [COLOR="Lime"][B]OK[/B][/COLOR]
Cocore-e 4.0 = [COLOR="Red"][B]NO[/B][/COLOR]
Cocore-e 4.2 (CWM) = [COLOR="Red"][B]NO[/B][/COLOR]
Cocore-e 4.4 (CWM) = [COLOR="Red"][B]NO[/B][/COLOR]
Siri RC1 = [COLOR="Red"][B]NO[/B][/COLOR]
Siri RC4 = [COLOR="Red"][B]NO[/B][/COLOR]
Thunderzap 4.1 = [COLOR="Lime"][B]OK[/B][/COLOR]

Something in the transition from version 3.9 to 4.0, disabled the perfect functioning of the application (read: not record anymore the incoming and outgoing calls).

Currently use: JellyMOD 3.0 (where all tests were done) and the Cocore-e 3.9.

And REALLY WANTED to use the latest version of the kernel, and not lose the functionality of CallRecorder.

So PLEASE tell me if you plan to add back the possibility of making recordings calls in your kernel?

Sorry for the large text and the poor English (I'm not native in English.).

I dont know what CallRecorder version do you use.

But i am 1000% sure that i have done anything about call recording in kernel.

Just now i downloaded CallRecorder 1.3.4

And tested.

It works!

I made a call to my CMCC and my bro.

The app can record my voice and my bros voice.

When calls come/made,it records automatically.

But,use Standard API,dont use KERNEL API.

[Galaxy S Advance I9070 Original Android Developmen] cocafe:
Re: [Kernel][03/05/2013] CoCore-E 4.4

This is easy to implement.

But i dont need CRT animation....

Please note that any OC app needs kernel supports.

Compare to 4.2,4.4 only added swap support.

Why i called it 4.4?

Because that the name is even number means stable version,otherwise it is beta version.

Since i have got my SGSA first day,that the battery drops from 100% to 90% only needs 20mins.

This is normal.Stock kernel is the same.

When the charging reaches real EOC,it will stop charging in mins.

You charged 8 hours,it has been used battery for 5 hours,it drops faster.

So that is why i want you guys unplug the charger when reached real EOC.

Besides,you can see charge_status in eoc_status folder,it tells you charging status.

And about the development:

I cannot dev at school,so when i get home on Sunday,i can enjoy the development with Pentium4.

Today(GMT +8),ab8500 codec control improved.Touchboost is improved a bit.

And others,keep it secret.

I cannot release it immediately,i must test it for days and confirm it.

I must be responsible for you guys.

And i would like to tell you something bad.

After doing some hacks,i realized that ab8500 chip is the early version.

It is not ab8505 v1/v2/v3,it hasnt supported speaker gain etc etc extended features.

Thats a pity.
