Does kernel flash in Recovery? - Xperia Z2 Q&A, Help & Troubleshooting

Coming from my HTC One X, the bootloader was "locked" in such a way that I had to flash the kernel in fastboot every time...
Does the kernel in the ROM zip files flash from the recovery on the Z2 if I flash the ROM from recovery?

i dont fully understand
you must unlock your bootloader to flash a kernel with xperias otherwise it will brick
when you flash a kernel it stays that way untill you flash another kernel
some stock based roms contain stock kernels so you will have to reflash a kernel which has a recovery
take note recovery is contained in custom kernels

So are you telling me that ROMs flashed on Locked bootloaders do not flash kernels?

Yes, that's correct. Locked bootloaders can only use stock kernel. To flash a custom kernel (i.e. non-stock), you need an unlock bootloader. So if the ROM is for locked bootloaders, then it's not flashing a custom kernel, so to speak.

S1bootdriver installer for flashing your phone

Hi,
In case anyone (like me) has issues installing the S1boot driver for your xperia, to be able to flash other firmware, here is the link :
http://forum.xda-developers.com/attachment.php?attachmentid=718060&d=1315877046
This driver will install itself after you run the executable file dpinst.exe after having extracted the archive.
With the driver you can use the flash tool (combined with your phone booted in flash mode (volume down + usb connect)) to flash other firmware on the phone.
P.S. i'm not talking about fastboot mode, but "flash mode" ;-)

i dont think you have to unlock the bootloader to flash your phone, you have to enable usb debugging in your phone ,settings>applications>development>usb debugging
pls correct me if im wrong
Hi,
As far as I know you "have" to unlock the bootloader before being able to flash custom firmware on the Phone.
I unlocked the bootloader via the sonyericsson site link :
http://unlockbootloader.sonyericsson.com/
I use 4pda.ru firmware+kernel from this thread :
http://forum.xda-developers.com/showthread.php?t=1424121
Reason I dont use CM or MIUI is that I need a 100% functional phone (both corporate and private usage, that's why) . I encourage the development on CM and MIUI, don't get me wrong here
You can find more information about unlocking, rooting and flashing custom kernels and firmware on this XDA forum.

You can setup CWM and flash ROM on unlocked device, but you can't flash kernel and baseband.
So current situation is: you can't flash CM or MIUI (which requires their own kernels) on unlocked device, but you can flash stock-based mods like repack4pda (which works with stock kernels).

I don't think so
No, kernels can only be installed with unlocked bootloader.

I'm on rage kernel 3.0 and stock gingerbread
I want stock ICS are there any method for flashing stock ICS without using
Sony PC Companion??
If you're using a custom kernel then it wont boot after relocking, so you need to flash a stock kernel and a ROM that works on it.

I flashed stock kernel using this one

Hmmm...flash the whole packages including the firmwares from that link then re-lock your bootloader....
if you want to use stock ICS, then you don't have to re-lock your bootloader....just flash ICS custom kernel, then flash stock ICS firmwares.....

Xperia mini pro root CWM Recovery after

Hey guys long ago I rooted my xperia mini pro and put CM 9 or 10 then I went back on Stock then again i put some radom kernel and and rom, then i wanted to put a rom here from te forum but when I put the kernel and try to go to recovery it wouldn't start the recovery the screen is just black
So i went back to stock !
now my question is how do I root again X_X
and how do I put CMW reocvery, because I want to put this : http://forum.xda-developers.com/showthread.php?t=2220537
maybe you can find here what you search
http://forum.xda-developers.com/showthread.php?t=1842366
and 4.1.2 is not ICS its JB
Since u tried cm, I am sure ur bootloader is unlocked.
So the easy way to root now would be to flash any custom kernel. It will be prerooted.
If you still want ti retain the rooted stock rom
Flash kernel and flash stock excluding kernel
Or flash stock and then flash kernel

Yes most (I believe all) custom kernels will have cwm ( or twrp,) so yes.
Try goin to dev section and find the list of kernels in stickies and find a jb kernel.

Unlocked bootloader and root made my WiFi stop working

Hello, i unoficially unlocked my bootloader then rooted my phone. I didn't flash my boot.img but did i few researches and cooked my own boot.img and flashed it but wifi isn't working. Pleas help me
Again flash a custom rom. Make sure that your bootloader is till unlocked.
Your boot.img is the culprit..... Flash a custom kernel according to the rom you r using...
