Can someone tell me what's the use of flashing a kernel? What's the difference between it and the boot.img? Also ,can someone tell me how to flash a kernel, do I have to reflash kernel after I flashed a custom rom? thx
People flash a kernel because some kernel support overclock, so u can overclock your phone. Idk if flashtool can flash custom kernel because I flashed sspeed kernel for acro s using cwm recovery (.zip) not boot.img

To flash a Stock Kernel u do not need to unlock bootloader.
Boot loader unlocking only requires for custom kernel.
For more in detail, go to the thread i mentioned above and read.

U have to unlock ur bootloader to flash that kernel.
What "code" do u mean?
I am not clear about your questions, What code you are talking about?
The link u gave contains modified stock kernel, not completely stock kernel. to flash this u need to unlock boot loader.
With locked bootloader u can flash only those stock kernel which is not modified or the kernel attributes aren't changed.

For some custom roms you need to flash kernels via fastboot and for this you need unlocked bootloader.
if bootloader it's locked use Google and search there is official way to unlock but you will lose warranty and drm.

First flash any kernel you want instructions will be given from where you will download like doomkernel it has inbuit recovery. Reboot into recovery choose your rom
Wipe system,chache,dalvik chache install zip from sd card
Dont flash ics rom over gb kernel or gb rom over ics kernel or it will cause bootloop

Considering you already have flashtool and your desired kernel follow this :
1) Plug in your phone in fastboot mode [S-Off, hold menu key and plug in to PC]
2) Place you .img on your desktop
3) Open up flashtool, select fastboot mode and select flash kernel and select it from the desktop
4) Once kernel is flashed un plug your device restart it open up CWM and flash desired ROM.
Hopefully i helped you out

kernel is an .img file so flash it normally as you do flash kernels...

After flashing the kernel you often need to flash Wifi Modules in recovery

You need to unlock your bootloader. Root is not needed at all.

Yes root is not required so tell what exact error you are getting and first confirm that you have adb drivers installed

Hello,
I need to get my phone back to stock. I'm running NXT Lite with DoomKernel V14 and I want to get it to a stock state. Could I just Boot to flash mode and ftf R800i 4.0.2.A.0.58 to go stock?
Yep. Bootloader will still be locked though
As he has doomkernel his bootloader will stay unlocked. if u want u can lock bootloader after reflashing stock rom and than u will be fully stock.

Not too sure why you would want to relock the bootloader. If u want to return to stock just flash the .FTF via flashtool and leave it at that.....just incase you want to install a custom ROM/Kernel again. Otherwise u will wish u never relocked bootloader

Just download the stock ftf file
Place it in c:/flashtool / firmware
Run flashtool
Go to flash mode
Flash the stock Rom
Reboot your phone..
Feel free to ask questions of you dint understand anything
1. I wanted to know that is it possible to downgrade using flashtool e.g if i flash a custom rom which is based on firmware .55 but then i flash with flash tool, version .50, would it work?
2. By flashing through flash tool, can i get rid of CWM?
1) yes
2) yes
Assuming you have an unlocked bootloader and you mean flashing ftf files

No. I'm not planning on unlocking bootloader but yes i was referring to ftf files. DOes it change the scenario?
Anyone?
The custom rom part put me off, sorry about that.
You can use flashtool to flash a stock ftf firmware over any custom rom. (also with a locked bootloader.
You could downgrade even to a gingerbread rom if you want

Ok and by flashing stock ftf, i would get rid of even clockwork right? in case of sending it to repair centre.
Thing is, i have played around with custom roms on different phones for ages but the whole part of unlocking bootloader etc is all new to me so before i begin flashing roms.
Yes it would remove cwm since it's embedded in the kernels and since stock firmware kernels don't have cwm it will be removed by flashtool when flashing a stock firmware rom

First flash stock Kernel, and then Relock, If you relock/upgrade your FW, before reverting to stock kernel, your phone might soft-brick..
