Can I flash Kernel using CWM? - Android Q&A, Help & Troubleshooting

I see a lot of video flashing Kernel using CWM on Youtube, but i don't see no body in this forum do it, only flash Kernel using Flashtool..

Sure can, just download it as a zip

Does Cwm support the galaxy s3?

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.

Yes, I have Xperia device WT19I, so my only option is using flashtool right?... Thanks for the info, I didn't know that.

Or direct fastbiit, but flash tool is much easier

No you can't flash a kernel with a locked bootloader except in a few rare cases. What device do you have?

What do you mean by "download them as a zip"is there any way to add kernelxxx.img file into a flashable zip file?

does this flashing via CWM ban apply for unlocked boot loaders? im using a Xperia arc s LT18i

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)

YOu can simply replace kernel if you are using any custom ROM on locked kernel.
Then you can simply copy and paste it (overwrite)
EDIT: As I know, this cant be applied when on unlocked bootloader (you havent noticed it before).
Yeah, well apperntly im outta luck i geus. My x10i is rooted + unlocked bootloader, but im running 2.3.3 gb.... No custom rom, about the kernel i dont know if its stock or custom, i would have to take i look at google to find it out.
Edited: And yeah, looking back it would indeed bin better if i posted this info in first post.
After all it looks that im gonna have to borrow a pc by a friend.

Yes, info is correct. Locked uses xrecovery, but unlocked needs flashtool & pc.

Installing cwm is possible only by flashing a pre rooted kernel through command prompt using fastboot method.

ROM Manager
hi,
yes, it works, indeed (LT26i 4.0.4)! And in opposite to RecoveryX. Fortunately now I can get into recovery mode but is it compatible with ROM Manager from CWM? Because for me it seems not.

You can Install a kernel in fastboot only!!
1. Shut down your phone
2. Hold the volume down key
3. Plug the USB cable and release the volume button
4. A blue LED should light
5. Flash the kernel.
6. Enter CWM and delete all the caches

I wiped everything... and found out that ROM can't be installed...

Hi there.
I got a quite serious problem as I recently wanted to flash CyanogenMod 11 on my Xperia Sola.
The problem is I downloaded it, placed on pseudo-SD card and wiped everything. Then, when I tried installing the rom it gave me an error of "assert failed" crap...
Mounting USB does not work and Windows cannot install drivers (even with PC Companion on).
I think I just broke my phone... It's stuck on Sony logo all the time and I can't even get into CWM now... [email protected]#!k.
Help please? :/
Hello. I don't own these device. But try to flash stock FTF with Flashtools and it's should be fine.
