What is this:
This is the Verizon Xperia Play R800x Stock Kernel for 2.3.3 WITH OVERCLOCK TO 1.6GHz.
What works:
Absolutely EVERYTHING!
What doesn't work:
You tell me.
Who deserves credit:
KeiranFTW <-- This Guy
and all our other developers which always have helpful info when I google something!
Story:
KeiranFTW made this: http://forum.xda-developers.com/showthread.php?t=1400127
but WiFi was broken for R800x.
So I fixed it!
How? Used his kernel with stock ramdisk.
How to use:
1. Download file attached to this post: r800x-stock-overclock.img
2. You must have unlocked bootloader.
3. using fastboot type in the following command:
Code:
fastboot -i 0x0fce flash boot r800x-stock-overclock.img
4. This will not erase your data.
5. This has only been tested on R800x with stock 2.3.3.
Note:
The original kernel had recovery added (by pressing back button on boot), this one does not have that recovery.
You can use this recovery instead: https://play.google.com/store/apps/details?id=com.pvy.CWMinstaler, after installing press VOLUME DOWN after bot to enter recovery.

Great job! Any chance of getting the recovery back in the kernel tho? Either way, again, great job!
Bravo good sir, bravo, keep up the good work!

Sorry, probably not ... is there anything that the recovery in kernel does that the one that gets installed with the app doesn't?

It's kinda nice having it in the ramdisk, because then you never have to worry about it (because it works on boot, no matter what )

I see, that makes sense ... If you flash a custom ROM and it goes wrong you'll have to get back to a PC to fix it if you don't have recovery in the kernel.
Ok, I can try ... But I've never done that before so any pointers would be great.

That is what I was thinking ... We would be back at square one.
For learning purposes I will go in there and figure out what they change to get recovery on the kernel ... If I can add just that to the ramdisk then it shouldn't break WiFi.

Well, yeah. If the /system directory is wiped you essentially wipe the recovery.img that the app installs, whereas the recovery would still be available (when inside the kernel) provided the boot partition is still there

It depends on your phone model. Because you mentioned flashtool I'm assuming you have an Xperia device. You can't flash kernels from cwm.

The post above answered your question and the answer is NO.
OK and thanks.
Thank you very much for the information
Hello everybody,
Please bear with me a little and if you would like to answer, please give as much details as possible.
I have and Xperia Acro S, with unlocked boot loader running a custom rom with stock kernel 4.0.4, and I have root access, and CWM installed.
I am trying to install a cyanogen based rom, with a custom kernel obviously.
I have downloaded a zip file which contains a boot.img file.
The developer asked to flash the boot.img using flashtool first, then to flash the rom with cwm. And here's my question(s)
As I understood, this boot.img contains the kernel, do I need to use flashtool if I already have CWM installed, or would CWM install the kernel also?
And let's say i extracted the boot.img from the zip file and flashed it, wouldn't this remove CWM from the phone?
And then, should the boot.img stay inside the zip file while flashing it with CWM later? or should i remove it because CWM can't flash boot.img?
I have successfully installed cyanogen roms on nexus s, with CWM alone, and the phone booted normally, and I suppose it replaced the kernel correctly, or it didn't?
And please if you could explain what exactly this boot.img is, and how is it different from a normal kernel file inside the zip, does it also contain a recovery? you get my point.
Thanks for reading so far, and thanks in advance for any answers.
i have xperia tipo and when i go to flash vengeance kernel with flashtool says:you need to be root and e.g.
i have unlocked bootloader and rooted phone!!!!!!!!please help me!!!!!!!!!!!!!(sorry for my bad english)

It is pretty self explanatory.if you want a 3.0+ kernel, then merge a 3.0+ kernel into your source. Most aosp kernel track from the linux kernel. I am not going to get into the step by steps about it, that you can google.

One of 4 things, Wait, merge from the linux kernel, merge from a 3.0+ device with similar hardware, or cry about it.

No, pending your source, and the other source, there are way to many different changes that could take place. I would use a tool like beyond compare and diff the folders to see what files are different, then based on your experience, start making changes, compile test, rinse and repeat.

Before you start working on it, nandroid backup your system. Its just the kernel, so you can always revert via recovery. Though you should already know that.

That is crap the kernel gets initialized during boot, unless your kernel is flashing a recovery as well, or your using a device without a dedicated recovery?
What do you mean by a dedicated recovery? I am using a samsung phone and we have a recovery mode and a download mode. We have both a permanent cwm and a zip fiw cwm(temporary).
Sent from my GT-S5360 using XDA
the dedicated recovery is a partition on is own, so lets say your mtd/emmc is structured like this
boot
recovery (this should be the dedicated recovery)
system
data
therefore you will be able to delete/flash/reflash the boot without affecting the tablet/system/other partitions
There are some devices that have a different recovery structure (tablets based on the rockchip soc)
Thanks for the help you both! I will learn more about partitions in my phone and come back on this thread.
Sent from my GT-S5360 using XDA
I guess most Samsung phones doesn't come as a recovery partition, it comes as an extra ramdisk as mentioned here.
Anyways I've flashed boot.img which I've compiled, and the first boot was a bootloop, of course. And after doing some changes, compiled again and flashed, and it was a success. So I don't think Kernels can hard-brick the device (IMO though).
For samsung...as long as you have download mode your in the clear...with download mode you can use Odin or heimdall to flash a working kernel or even stock software to return to stock.
Samsungs do not have a partition for recovery...its its own ramdisk..."recovery-ramdisk.img" so you can lose both recovery and boot with a kernel but with download mode and heimdall all you have to get is a working kernel with a working recovery, open terminal and type "heimdall flash --kernel kernelnamehere.includinganyfileextention" so "heimdall flash --kernel boot.img"
Sent from my SGH-I997 using Tapatalk 2
You guys rightly said! We have a ramdisk included with a zImage in a boot.img. I have also seen cases where the recovery mode doesnt come but the download mode is still intact.
A guy from our forum once flashed a s2 kernel on my Y and he hard bricked it. No modes were opening on his phone but according to the theory given by you guys, atleast the download mode should have been working! Care to explain me why that happened? I think the same thing will happen with me when I use sources of other phone for my kernel.
Sent from my GT-S5360 using XDA
So what I read from this thread, if you don't have a recovery dedicated for your device you would hard brick it???
Coz I tried n tested some kernels
They didn't work out -but it was a soft brick
Not a hard brick
I had not made those
Now I'm willing to try once I get some hold on building kernels
And I have a Sony Xperia Neo V
It doesn't have stock recovery like Samsung so if I make or atleast try to make kernels on my own, would I risk my phone getting hard bricked???
Or just soft brick?

Hello.. can anyone explain to me what is BOOT.IMG? and this is improtant on flashing ROM?
I'm not sure what it is, but it somehow manages the boot process. Every ROM has its particular boot.img. it is needed, but it is included in all roms around here. So if you flash a rom via cwm, boot.img is flashed to your phone automatically. Why do you need to know?
Wow... Its the kernel. For the OP. For the other replier. Please dont give false information.
Sent from my GT-I9300 using xda premium
Actually your both kind of right. A boot.img is a kernel smashed with a ramdisk. The kernel sets up internal hooks and initializations to the android os. The ramdisk contains a set of instructions and such to also create the hooks. In general a kernel is a binary image that contains all the drivers and such for a system to communicate with the hardware and the ramdisk initializes the hard ware
Please do not shoot people down. Some are just trying to be helpful.

Oh no no. You are going the Samsung way I guess. In all Sony phones, we dont have a recovery partition. That means that we can't flash kernels from CWM. The only way is fastboot. So no way to include kernel in your rom zip file. Sorry. At the most you can only recommend users to use a particular kernel.

so if i cant use a custom kernel .. how do i extract the kernel.sin into the rom?
Basically you just can't flash kernel with the phone.
Usual practive in our phones is to include th boot.img in the rom file and ask it to be extracted and flashed via fastboot through pc.
Hope it helps

Hi,
You can use the attached META-INF folder. It has only the basic stuff like basic symlinks and permissions required for the rom to work properly. Just check the comments in the updater-script to know where to add your tweaks.
Good luck developing
