Flashing Original Kernel

I want to have a test of some of the custom kernels on XDA... is there a way to backup and restore just the kernel or is there a flash-able package available somewhere with the original kernel?
Cheers

Download the stock Google images. Unzip them and find the boot.img file. This is the stock kernel that you can flash in fast boot. Be sure it is in the same folder as fastboot and use
fastboot flash boot boot.img

Thank you sir... just what I was after

I assume I can just flash the boot.img i get from a nandroid backup?

Unlocked bootloader, bricked due to flashing

Hi.
I've unlocked my bootloader last night successfully, and went on to flash a custom boot.img.
First I did "fastboot.exe flash boot boot.img", it went through no problems. However after that, my phone boots up to Sony Ericsson logo, it goes away and screen remains black.
I've tried to flash generic global ROM ( "fastboot flash system boot.img" ) to see if I can at least restore my phone to default ROM, it still acts the same..
Anyone mind helping ?

fastboot flash boot boot.img - flash kernel
fastboot boot boot.img -hotboot kernel
what file you flash for rom?.ftf or img?if .ftf you need flashtool,but for .img just use fastboot

I've used "fastboot flash boot boot.img" as my first step.
The file was .img, obviously.

Flash it back to stock with FlashTool and try it again.

Heh, I haven't realised that .ftf files flash the entire thing INCLUDING kernel to the phone. Oh well, we learn every day
Thanks guys !

[DEV] recovery

attached is a semi-working recovery, you can flash it with "fastboot flash recovery recovery.img".
update: the recovery can flash boot.img's too, if the custom rom uses "dd" instead of "write_raw_image" to flash the boot.img. i hope mike updates his rom
don't use anything except for "install from sdcard"
i take no responibility for any harm to your device or data
it's basicaly a repacked cwm recovery combined with the stock 1.26 recovery kernel/ramdisk with modifications to init.rc
it is intented for developers wanting to toy around with custom roms, until someone makes a real recovery
no support nor updates will be made for this

is it tested or not yet.

I've tested it

ok thanks, since currently there is no other option to unlock bootloader other than htcdev & lack of RUU sources is too risky to flash custom recovery at this point. so technically it will skip zip package signature check? so we can start working on working custom rom.

You can always flash the stock recovery again ith fastboot
The reason why this recovery is useful is because i dont have to repack system qnd userdata images with ext4. Plus, you can update the userdata partition. Flashing with fastboot erases it

looks nice!
could you maybe share your knowledge about creating this recovery? i'm trying the same for the one s but can't get it packed together correctly...

Do I have to unlock my phone to install this recovery?

yes, there are only 2 ways of installing a recovery.
fastboot and adb
fastboot requires you to unlock in order to "fastboot flash recovery"
and in order to possibly do it through adb you need root and in order to get root at the minute you need to be able to flash an insecure boot image through fastboot, which again, you need to unlock in order to "fastboot flash boot"

Hi blubbers,
There is a guy on general thread who wants to dump a developer phone. It's s4 not tegra but might help.
