[Q] ANSWERED!! NAND.. can you change kernels?

Hi guys,
Is it possible to change the kernel of a nand build at all?
I am an Extended Battery user and find only NAND builds with Hastarins kernel work at all..
Is there a way of mixing and matching Kernels with builds?

Yes
Just made something for you, note: haven't tested it:
Kernel Theiving
How to:
- Install Nand version which has the kernel you want.
- Run "extract_kernel.bat"
- Install Nand version you like, and want to keep.
- Run "install_kernel.bat".
- Et voila!
Now, you only have to use "install_kernel.bat" if you flash another rom.
Note: You need adb installed on your PC
Quickie on how to install adb:

You need adb:
-Get this installer: http://developer.android.com/sdk/index.html
-Go to Available Packages, Expand Third Party - Google - select USB Driver
-Update adb driver, if not already installed from: C:\Program Files\Android\android-sdk-windows\google-usb_driver
-Copy "adb.exe" and "AdbWinApi.dll" from "C:\Program Files\Android\android-sdk-windows\platform-tools" to "C:\Windows\System32".
-Run the batch file.

I read the batch file and
you have created a folder called boot under data folder and pasted the zimage
so everytime when we boot out Hd2s it going to replace the zimage with the one in boot folder, so i guess its going to delay the booting process (correct me if im wrong) so is it possible to delete that folder after booting our Leos?

No, that's not what it does. it mounts the boot partition temporarily to /data/boot, and after it's mounted, adb copies over the zImage file, and overwrites the preexisting kernel image, after this, the partition is unmounted. So it's not repeated at each boot.

works a treat...
I just used Android commander..
made sure it was connected..
then ran the extract batch file
installed the nand build i wanted...
then ran the install Kernel.bat
and it works a treat!!!!

Is all that done on the phone? It seems you installed the kernel on the phone somehow. I'm clueless about adb, I tried to use it before but was dumbfounded by it all.
Do I need Eclipse? Downloading the SDK stuff...installing JDA SE and it talks about Eclipse.

[CWM] [Flashable] [Only for Aurora 4.1a] Updated init.d support

I'm sorry to have to open another thread just for this, but I was waiting for zephyr1988 to update his files for aurora 4.1a. As he didn't do it yet, here it is
I had posted these in the other thread, but the files are now outdated and there was some confusion regarding the kernel inside the zip. These files, fix this, because I updated the kernel and services.jar for Aurora 4.1a.
Please, to understand what this does, read this thread:
http://forum.xda-developers.com/showthread.php?t=1710233
Notes:
- This is only for those with Aurora 4.1 + 4.1a update. For other versions, there will be auto-reboots, especially with the gallery, so, if don't have the latest aurora version, don't install this.
To install, flash both zips in recovery. Boot takes a little longer, but believe it, it's worth it

Sorry if this question was already answered.
What are the changes in the boot.img?
dzo already added support to run init.d scripts already in kernel of the versions 4.1+, correct?
Why you need to add it to your zip?
Another question, what does the OOM_Priority_Charger_Aurora_4.1a.zip?

Couldn't flash OOM_Priority_Charger_Aurora_4.1a.zip through recovery, says installation aborted..

It's the same one that's in update 4.1a, I kept it because there was a boot.img in the original script, I don't know if removing it would lead to the script not working...

It's working here, I tried it again just now... what CWM are you using? You can also just extract the services.jar that's inside the zip, and copy it to /system/framework, replace the default and set permissions like the default and reboot.

If I already have the 4.1 or 4.1a installed I already have the boot.img in my phone and It already have the support for init.d. So I think you do not need to add it to your zip.
That is creating problems only.
This is just a comment to improve your work and correct me if I'm wrong. I'll appreciate.

It doesn't create any problem at all, because I didn't modify the 4.1a kernel in any way, it's the same that it's in dzo's 4.1aupdate zip.
On the other hand, removing it could cause problems with the updater script in this flashable zip, that's why I kept it in my flashable zip. You are not forced to install this zip if you don't want, but I can guarantee the boot.img is the same that's in dzo update, there's nothing bad coming from flashing it.

Hello fjsferreira,
Thanks for updating the zip, I was away for a week with no access to a PC.
I have updated the original thread with 4.1a OOM priority charger and a init.d zip that does not mess with the boot.img now that dzo has included it in his ROM, so it should be compatible with newer versions.

I ve read the threads but still dont know what is OOM priority charger or any charger and init.d . Can someone explain it to m?

These are scripts that run at boot time to change memory management so that you always have a good amount of memory available. The package also contains some scripts to fine tune screen sensitivity, sdcard and CPU performance, those require editing the script files to uncomment some lines. Read the instructions on the other thread to fine out how to use this.

Custom Recovery INFO

OK . We all i believe find it chaotic to organize in forums now. So this is a thread just for ideas and problem with cwm or twrp on our device.
All that i have found now is that recovery.img is somehow backed with boot.img. So i have to ask if there is any developer that can look inside this.
Help appreciated. We (developers) have already compiled TWRP and CWM ( me via ubuntu and clockworkmod recovery builder) and none of them is booting.

You might want to look at xperia p boot.img??? Same processor u8500 same screen size. I'm a noob. Just said what I felt. Coming from xperia device where our recoveries are always packed inside boot.img
In ramdisk . /sbin/recovery is where our recovery binary is present.

Perhaps need to no only make recovery but also kernel ?

Sent from my GT-I8190 using xda app-developers app

From what I understand, You just need to write a piece of code in the ramdisk init files to execute the recovery during boot. No need to modify the kernel.
#pitchblack5691#

If any one is interested i got a dumped ram disk also a got it rebuild-ed,
and yes the recovery scripts are there plus the pngs etc.
I also believe that the device has 2 recovery's, they are the same one just acts as a backup.

is an idea
i explain when you make recovery and extract it you find some files inside ( fstab , RC , init , propr ...
now we have also one with CM device info the device have not CM rom and also have not CM kernel her why i posted this comment because when you extract stock recovey you find kernel part and when you extract boot.img find recovery part now this 2 files perhaps have dependency to work together ? is an idea do not yell at me :silly:

I sent info about device to that developer. That app is now supporting our golden for full backup incl boot & recovery.img with .zip from here. Only problem is we dont have a working custom recovery to flash that .zip with :/

as Faria wrote above should change the recovery that is in the kernel and the same meter and the same rom in it and in the kernel for which you go just tell me that the two are complementary if a move (size , addition, retirees), the other answers are more about the two is that one feature that the other is that we will say to his control as .

2ndboot with working radio

First I want to say thank you to czechop for his patch and all his work and for telling me wich files to mod to have radio working.
I want to say thank you to fjfalcon and Mioze7Ae too for kernel sources and all their work for our phone.
Currently phone boot on 2ndboot kernel from OpenRecovery with a script.
It boot slow and with some bugs but it boot and ask for pin code and radio is working (I was abble to make a call)
So 2ndboot kernel sources are here : https://github.com/Zachary57/android_kernel/tree/kernel-mod
Kernel image is attached
To use (at your own risk) :
1-Download zip attached
2-Extract 2ndboot.zip to /system (2ndboot.zip is on attached zip so you need to unzip 2 zip) and 2ndboot_system.sh to /sdcard/OpenRecovery/scripts
You should now have /system/2ndboot folder on your phone and 2ndboot.sh in /sdcard/OpenRecovery/scripts
3-Reboot phone holding volume up to boot into OpenRecovery
4-Select run script / 2ndboot_system.sh
It will run script /sdcard/OpenRecovery/scripts/2ndboot.sh that call file in /system/2ndboot
Specifications :
-Kernel OC to 1GHz stock voltage
-SWAP
-Smartass V2 governor
Problems :
-It sometimes fail to boot.
-Sometimes 2ndboot stop to work (you have infinite reboot) so you need to erase files and download them again to make it working

For now I am learning kernel developpement but I will try to update this.
In kern.zip all work like with stock kernel. I just applied czechop patch on Mioze7Ae kernel sources and czechop tell me what line was wrong.
I don't know if swap work. I think it is on kernel but I can't make it working for now.
[UPDATE]
Swap not implemented on kernel. I will try to implement it.

It doesn't install it just script and files that you copy to sdcard. Then you run script that load 2ndboot kernel. You have to do that on each reboot while we don't put a script that make that automatically at startup.
When you hit 2ndboot.sh in OpenRecovery/run script it take approximately 2minutes to start boot.

where put kern.zip,and where put core with swap support? for example boot3.img.I run script 2ndboot.sh and its install and reboot,but how use 2nbdoot?

When you run 2ndboot script it run custom kernel that is provided in zip. kern.zip is already on other zip. It is kernel image.
You can't boot boot3.img you can only boot zImage (it is what is kern).
Kern is a zImage it contain custom kernel modded to keep radio working after 2ndboot.

how install kern.zip? and where put him?

Great job done man.
I will look at cm10 for xt720.
i had been working this and very happy you succed in 2ndboot working.
I will switch back to xt720 and try this.
Thanks for your work!!!

Don't install it. Just extract files from 2ndboot.zip :

Kerel reboot take about 2 minutes. It is long but it work everytime (with usb wire disconnected) I tried.
Can you explain more "do put kernal main storage card ?" I didn't understand that part of your sentence.
I use Mioze7Ae 2ndboot files from here : forum.xda-developers.com/attachment.php?attachmentid=1388600&d=1349812889

In fact custom kernel is kern (it's a zImage file) and is located in /sdcard/2ndboot.

Custom Kernel SM_G935F

I have been playing around with kernels (for nexus 5), to add some features to the stock kernel. But I have problem with Samsung. I am trying to build a flashable custom kernel for Samsung S7 edge (G935F). .Steps I followed to create the boot.img are:
Get the stock source code (Samsung openSource)
Modify the kernel (just add/remove some TCP features)
Build the kernel (as per the kernel READ.ME, with aarch64-linux-android-4.9 toolchain)
-->created Image, with no loadable modules (*.ko)
Unpack the boot.img from the stock kernel (abootimg -x )
Create new boot.img replacing the original zImage with the custom kernel Image (abootimg --create . . . )
Make tar.md5 file of the custom boot.img for Odin3
Pushed the custom kernel using Odin3, but it fails to boot ("kernel not enforcing seadnroid"). I have tried using TWRP (install from zip), but it just does bootloop. Can anyone see what I am doing wrong? Am I missing something? I have read most of the "Build kernel from source" dev-threads but have not found a solution for this, nor am I allowed to post my questions there as I am just a junior member.
I would highly appreciate any help, as I have already invested some days with no avail

I dont want to tell you something you have already read, if you have been through the Dev forums, But on the off chance:
Have you removed the Fingerprint reader?
The Kernel will fail to boot with it enabled, Unless you know the workaround (EchoTeam)

Hmm ... Fingerprint reader? No, I have not removed anything. I was thinking that since I am not adding anything that was not already in the stock kernel source, I do not need to do any modifications. How can I remove this reader?

Here are the temporary solutions.
Way A:
Remove /system/lib/libbauth* , /system/lib64/libbauth*
Way B: (If you want to completely disable (or bypass) TEE)
Remove /system/lib/libbauth* , /system/lib64/libbauth*
Replace /system/lib64/hw/gatekeeper.exynos8890.so,/system/lib64/hw/keystore.exynos8890.so with these i uploaded.
Both of them will make your FP Sensor not working.
(Lock Screen will work)
But,at least,you get a stable custom kernel.

I saw someone mention me.
Well, you must disable all TIMA-related configs as well as KNOX_KAP to get kernel boot.
And then, if you want to get a stable kernel with FP, you must apply my FP fix.(could be found in my Kernel's flashable zip)

I appreciate that you have had the time to look at my question. I've tried the tricks you suggested but my kernel still cannot boot. Modified the .config file (with menuconfig):
disabled
# CONFIG_KNOX_KAP is not set
# CONFIG_TIMA is not set
# CONFIG_TIMA_LKMAUTH is not set
not in config anymore
-CONFIG_TIMA_LOG=y
-CONFIG_TIMA_RKP=y
Then built a custom boot.img as mentioned in my question and added the META and mcRegistry folders from your flashable zip file to create a zip file out of the three.
I have also tried by removing the libbauth* files from system/lib/ and system/lib64 directories?
One more thing, does it matter whether I get just an Image file or zImage from kernel build (I get only Image and .gz of it)?
