Can you give us an overview of what you did with your kernel? I.e. What functions have you put in and/or what you took out of it?.

Like oc, uv/ov, and this like that.
Would greatly appreciate it.

Did I help? Then please don't forget to press the thanks button.

I did, its in the features, I took nothing out, and only put in root and recovery. Also, I changed the bootsplashsceen, (But it doesnt look good at the moment and i am working on making that better)

I will start loking at OC/UV/governers/IO schedulers etc in the future...this is a learning curve for me as well.

crazymister · Nov 25, 2012

My bad, didn't realize that was what you did. Anyway i look forward to any future work you may deliver.
And it's not bad that you're learning, hell I was thinking of trying to do that too but haven't had the chance yet.

I am from 3.195 and from an unlocked bootloader back to (re-)locked bootloader (tested with update service) and then flashed the phone to 1.303

You also wrote in the "Full rooting.."-thread:

gregbradley said:
1. flash a 303 firmware (If you are already on it, no need)
2. Root phone.
3. Install cmw for for locked bootloader.
4. Install my 195 rom

I rooted the phone agin with Bin4ry's scripts and then i wanted to flash your kernel:

FAILED (remote: The Device must be rooted first)

The device is rooted and I installed CWM again, next try:

FAILED (remote: The Device must be rooted first)

what's wrong?

Thanks for help.

In this case rooted means unlocked bootloader.
If your phone has locked bootloader you CANNOT flash custom kernels.

If you want custom kernels then unlock your bootloader.
If you want a locked bootloader and root then follow the guide for rooting locked bootloaders in the all in one thread from my signature

My phone has had an unlocked bootlader. I wanted back to an locked bootloader und your posting does not says anything about unlockig the bootloader.

If you would have pointed out this I never would have tried out you kernel, because my phone has had 3.195 with root and kernelV4

Thanks for nothing, you don't help with half of the important information they are indispensable for using your kernel.

Reading is a wonderful thing

.img/.elf
These are kernel files. They can be flashed in fastboot.

Part 3. Unlocking bootloader
You must do this to install custom Kernels.
Follow the official guide from Sony. This is currently the only way to do it.

The above are taken from the noobs guide of the all in one thread.

This is from the first hit in a google search

Kernels

WTF is a kernel?
The kernel is the communication bridge between software and hardware, is the most important part of any OS.

All OS have a kernel, even windows and iOS but since android its based on linux the kernel must be a GPL. So manufacturer must be public the source code of the kernel and third party devs can compile and modify it.

Now since SE decided to open the bootloader of certain devices (and the_laser find the way to do it to the rest ) we can use those nice kernels we are talking about. And this is how to do it.

You will need:
•Unlocked Bootloader
•This fastboot pack
• A custom kernel (.img)

And finally this is from the OP of this thread.

Code:
Installation

Via fastboot

Code:

fastboot flash boot gregkernelV1.elf

I am not here to hold your hand, but to guide you through the process so you understand it. Please read this.

@op, instructions are clear, concise and I thank you for your ongoing work to support T users.

As i said, its failing because it needs an unlocked bootloader. The error message that says

Code:

Your device needs to be rooted

refers to the fact that your bootloader is locked, not the fact that your phone is rooted via bin4ry's method. Its a fastbootroot error (So means bootloder root status)

Anyway, you are completely entitled your opinion about me, I am only here to try and help, but if my instructions appear to be confusing I would appreciate some constructive feedback, not flaming or name calling.

Reported to MODS

EOD.

EDIT
@baz@gmx.co.uk thanks, but lets not start flaming. I have reported him to the mods, they will sort it out.

Maybe. That are two different things: making a good dev work and wrote a clear instruction.
I haven't react polite to your message and I pointed out why.
If you thing that MODs are necessary it's your choise.

By the way, after calm down I flashed a 3.195 again, relocked the bootloader again and flashed your V1 kernel, after that I found your V2 and flashed that kernel.
Nice XDADeveloper bootsplash, I like it. You see I don't dislike your work and I am nevertheless able to recognize that. Well done.
