hi . this is my first andro. i already done google but stil cant find my answer in right way.
i came to know it is in boot.img(corect me pls if i m wrong)
then why kernal sources is so big like 2 gb
and boot.img is just 4.7 mb in hd.
so finaly is kernal a softwear to make boot.img with linux?
pls clearify me.
During the ROM installation whether stock/custom ROM, boot.img flash to boot partition as image. So you cannot see boot.img in phone
If you want to change the kernel (boot.img).. You have to flash from recovery
the kernel is not present as a code or a single file in android...u can its directly the executable kernel present... the kernel source code has lots f things. and boot.img is not the kernel... its the boot image... not kernel image... it is loaded at the time of boot. before the kernel is loaded..

Hi!
I just flashed CM9 and a custom kernel on my Xperia Mini Pro (after some noob trouble), but I'm still having some problems.
I already did some searching but really can't find anything that works.
1. I can't turn on wifi, don't know if that's because of cm9 of the kernel
2. My hardware keyboard is now querty, and for some reason the option to change the mapping of the keys in cm9 doesn't work..
3. I can't change anything in the processor configuration
Help would much be appreciated!
Greetings,

You have flashed which kernel??

You have to flash the cm9 kernel. The boot.img that's included in the zip for cm9. You can't use the Karmarush kernel.
I think I already tried that.. Worked with cm7 but not with 9. How should I flash the kernel now? Can I just flash it or should I return to stock rom first? Or backup my data, do a factory reset and flash the both again?
Also, in the update guide on the cm wiki, it says to use this command:
fastboot -i 0xfce flash boot boot.img
But I read a lot about people just using the command without "-i 0xfce"
so fastboot flash boot boot.img
what's the difference?
It's the same command. Just open the CM9 zip and extract boot.img, then flash it using fastboot.
CM9 kernel has some problem, it is not succesfully booting up.
"FXP 127" kernel is recommended to use.....
Yeah, it appers that way. I tried a few kernels but the original cm9 kernel doesn't boot (black screen only).
When flashing fxp127, do I have to change the cm9 ROM as well? Or does this have nothing to do with it?
And, is there a site where you can download ONLY the kernels? Cause I found the free xperia project host from Google, but I can only find the changelog of the kernels, not the download mirrors.. I'm currently downloading the whole fxp128 with cm9 since I can't find fxp kernels separately
Okay, I flashed the FXP128 CM9 ROM and Kernel (think FXP127 is for x10?), and this works flawlessly! Should've done that from the start
Do I have to flash only the stock rom, or I will have to find the stock rom kernel too?
The kernel is already into the stock ftf, that's why when installing stock firmware you use fastboot mode as you would for the kernel

I don't know, because if we flash the stock firmware, we flash it in flashmode, not in Fastboot. I don't know if you should use for example rage kernel...
EDIT:: Sorry just tried it and you were right, I thought I need to flash the stock kernel again. Thank you very much
Did it thanks!
Well not really, the processes are pretty much alike. Fastboot is a flashing method that allows writing unsigned partition from host usb directly to the filesystem, which is disabled in standard bootloaders (which is why you need unoocked bl to flash most custom kernels) but if you flash the whole ftf (which already contains the necessary boot filesystem as it is standalone fw) you use flash because all installation steps are executed in the correct sequence...
Anyways, enough with the spam. Stock FW all have stock kernel embedded, just try flashing it and check kernel versions and ou'll see
Download official ftf file from Sony website and flash it via flashtool.. Kernel would be installed ... You don't have to worry...

Hello
I am a newbie Android user though I flashed Real ICS r6 and Extended Stock kernel a few months back. The ROM is great, the kernel works fine. But I wanted to Overclock and use Swap File which isn't enabled in extended stock so, I wanted to install MESA which is compatible with Real ICS as well as my phone. But I have no idea how to flash a NEW kernel.
If I flash a new kernel does my ROM get erased too?
I need a detailed step by step tutorial about flashing MESA and replacing Extended Stock with it, without removing Real ICS r6. Any help is appreciated guys. Also, please take note that I cannot brick the phone as I won't get a new one for years if that happens.
Thank you in advance.
AW: [SE Live with Walkman] Installing MESA Kernel over Extended Stock Kernel
No it won't erase the ROM
See my "how to install a custom kernel/rom", there you can see how to flash the boot.img using flashtool
Sent from my Nexus 7 running Android 4.2.1
The steps is so easy,
1-Download the kernel, extcract if it is a zip file
2-Get boot.img
3-And put it in your fastboot folder
4-Open cmd and navigate to fastboot folder,
Or simply click on start search for cmd and drag it in fastboot folder then open it
5-shutdown your phone
6-hold on volume up and connect the usb from the phone to pc
7-it will ask you for drivers ( skip if you already done so)
8- in cmd run the following commands
Fastboot devices
Fastboot flash boot directorytoboot boot.img
Replace directorytoboot with actual directory
It will not earse your rom.
And btw xperia 2011 is hard to be bricked

Thank you to the both of you, I have successfully flashed MESA 3.2 on my Live with Walkman. So far so good.
Try MESA Hybrid v3.6 kernel. It's better. Flash kernel via Fastboot and then flash mesa-hybrid-stock.zip via CWM.

live with walkman
i am only left with mesa kernel and its recovery..
i accidently wiped system while trying to install real ics ir6 yesterday..

Open the ROM.zip file and extract the boot.img file from there. Flash this boot.img file from TWRP and then flash any kernel you want.
Fyi if the kernels you're flashing have the same base then you don't need to flash the boot.img file before. If you don't know what this "base" is then just flash the boot.img file before flashing different kernels.
Thanks
