Easily Flash Kernel

I'm about to Root my Arc S running Stock ICS and Unlock the B/L to Install the Paranoid Android ROM & wondered if there is an easy & straight forward way to Flash the FXP Kernel that is required, as the last time I tried it I ended up bricking my Arc S and having to revert back to stock?

if u do it right you wont brink your arc s..
get into fastboot mode..open flashtools and select fastboot mode(lightening icon)..then click on "select kernel to flash",,then browse for it and within 1 second kernel will be flashed

Just did what you said and it worked fine, the FXP Kernel that I tried last time must have been faulty as I used the Kernel from Paranoid Android v1 FXP116 BASED and Flashed MooDeD Paranoid [AXP][xTremeFast][PORT][RC1-V1][xDonate] and everything went smoothly, now just waiting for it to Boot for the first time.

Try it manually and see or use an older version of the flashtool as it obviously isn't working properly.

Did you use "Select kernel to flash" option?

Need Help

Guys i need some advice with rooting my friend's Arc s. Here s what i did
Phone was on official ICS. I unlocked the bootloader using the official method.
Then i rooted it using some one click root method
Then installed recovery using recoverx software
Booted to recovery, wipe data, format system
Then tried to install a rom called racing bean. But i got and status 7 error. I tried some other JB rom.
But got the same error
Then i switched off and tried get to recovey. but could not
So i relocked the bootloader and installed official ICS again to boot the phone. The phone is fine now.
so can anybody help me to properly do this?? I just want to install CM on this phone

Racing bean or any other jb rom needs a JB Kernel too!.the ics kernel and jb rom mismatch might give that error.First flash a jb kernel and then it should work fine. This one's what i use http://forum.xda-developers.com/showthread.php?t=1885559.

First, you forgot kernel. Second make a backup with cwm before any wipe.

I flashed lupus kernel but after that i could not get into recovey. How can i do that?? I had the same problem with Arc fusion kernel

Well,there shouldnt be any problem,vol down or up button while the device lights up(led glows) does the job.But maybe u can try flashing it agn..if still having an issue..use an app like rom toolbox or boot manager to reboot into recovery..btw srry for the late reply

I gave up the effort. I tried about 6 Roms and kernels. Even ICS kernels with ICS roms. But After flashing the rom the phone does not go pass the kernel boot screen. I had to relock the bootloader and flash the stock Rom again. I have flashed hundreds of roms on so many devices. But never faced this kind of situation

Not sure why you would have installed RecoverX if you have an unlocked bootloader as all you need to do is flash a kernel that includes CWM.

I think you should flash kernels via fastboot.

Ya right i did flash the kernel via fastboot. Then booted into CWM and flashed the rom. But when i reboot it gets stuck at kernel screen

This happened to me and all I did was leave the phone like 10 mins booting, then it magically worked. I'm using Arc fusion 4.3 with racing bean, no problems. Try this, flash lupus kernel, wipe everything, go on fastboot and flash fusion, try to go on cwm and if it works, try to install racingbean again. At least that's one of the things I did.

AW: Need Help
Always give the recovery log...
& exact error code ^^
Than search google.
Than xda.
Than post ^^

flash newest sony ics stock rom-->fastboot kernel in the cm zip-->wipe all cm need-->use cwm flash rom-->use cwm flash gapp (goo.im/gapps) (ex: cm10 should be gapps-jb-20121011-signed.zip)-->enjoy!!
NOTE: If you are facing problems such as "Status Error 7" while installing, try THIS

So you didn't see the boot animation after kernel screen?
How do you flash the kernel? Did you see it finished successful on screen?

What happens when you flash it manually using the right command? See the link in my sig and Google before asking how.

Did you flash the kernel or did you hotboot the kernel?
Hotboot runs the kernel only once, flashing pushes the kernel into phone's memory.

What is annoying is that after reboot the wifi stop working in the phone and only a full nandroid restore make it work again.So each try take much time to restore my phone.

[Q] Will installing new ROM wipe X-Parts CWM?

Hi, question: I failed time and again to get CWM working, but finally got it to work using x-parts. However, x-parts is keen to point out that it is not a fully fledged recovery and that "if you wipe the system partition for any reason, it will be gone!".
Does this not mean that if I boot into recovery and install a new ROM (Going for the FXP CM10 one, if it matters), then when I wipe the phone beforehand I'll also wipe my CWM install, thus completely bricking the device? Would appreciate any thoughts, thanks

Yes, if you wipe the system partition there will be no more CWM. For CM10, you need to flash a custom kernel for it to work. This custom kernel will usually come with a CWM recovery so it will not be wiped when you flash a new ROM.

Thanks. But, to clarify, once I flash new CM10/Jellybean Kernel, my current Gingerbread install will also completely cease to function right? And I'd need to flash back to something earlier to get it to work, if I so desired?

Is your bootloader unlocked?
And yes you will have to flash GB ftf using flashtool
Sent from my LT18i

Yeah, I unlocked the bootloader and rooted it ages ago, but have since neglected actually updating the ROM, decided I can't live in a GB world anymore though.
So, as I understand it, process would be flash a new GB kernel to get CWM > Wipe Everything > Install the relevant ROM and GApps > Done? Does this ROM installation include the update to JB kernel then? Thanks

If I am not mistaken the kernel boot img should be inside the ROM zip. Check the ROM zip. Just flash the boot img using fastboot, boot into CWM recovery and flash ROM & gapps.

Ah, ok, well this brings me full circle. Because I'm trying to follow the boot instructions to do so, but:
fastboot -i 0xfce flash boot boot.img
doesn't work. I've taken the boot.img out of the ROM, and put it in the platform-tools folder. But whenever I try this line, it says it can't boot it, and quotes "no error" (no longer at home so can't quote the exact error, but it's something like that). I assumed the problem was me lacking CWM, hence was trying to install that first. Fastboot devices DOES show the device, and both fastboot and adb commands work in a terminal, but I just can't get it to boot into the ROM recovery for Cyanogenmod. Driving my crazy! Thanks

You don't need to add -i 0xfce to the command. Just type fastboot flash boot <name of boot image>.img

Ok, so finally got home to try this, still throwing this out: "error: cannot load 'boot.img': No error"
I've got the right boot.img in my platform-fools folder, the relevant CM build on my SD Root along with GApps. Drivers are definitely installed correctly as fastboot devices shows the device, as do adb command when it's on - anyone got any suggestions? Would be immensely grateful if this confounded problem could be solved. Thanks
