Hi... I'm not totally a noob, but I don't know what can I do now to solve this problem. I have an Arc S rooted and with unlocked bootloader. But when I try to install ANY kernel by fastboot, the phone starts with the new kernel's logo but it turns off. When I restart the phone, the stock kernel logo appears. Nothing changes. I flashed an general firmware already... unlocked bootload, rooted... Drivers installed... What else can I possibly do? Thanks.
Type fastboot flash boot boot.img

IT WORKED!
Thank you man!
But... Why did i have to type "flash" instead of just "fastboot boot boot.img?"
Fastboot has commands which you need to use.

"fastboot boot" will make a one time boot with the image you specify, while "fastboot flash boot" will flash the specified image into the boot are of the device. The kernel images are not made to be hotbooted like the recovery image. That's why you can't use "fastboot boot" with a kernel image. That only works with CWM images.

Hello everybody,
I managed to install the clockworkmod recovery for the Xperia play.
But I don't know how to reboot into recovery mode.
I searched a lot but I can't find the key combination for rebooting into fastboot/bootloader
or recovery mode.
Please help.
Turn device off. When off, press the power button, and start tapping the back button untill device boots into recovery.

Thanks. But unfortinatly thats does not work.
The device just booted up normally.
May be there is another method or I am doing somthing wrong?

I see you posted in the CWM thread, did you boot the recoveryPLAY.img? if so you dont have CWM installed, thats a temp image, your ment to boot from fastboot every time you want to use recovery. You need to flash a kernel with recovery embedded, if your using a r800i with the latest firmware, try doomlords kernel.

What is it, unlike other android device, on the play recovery is held on /boot partition. This is the same partition as the kernel. So if you was to just flash a recovery, this would overwrite /boot partiton, and because there would be no kernel, the device wouldnt boot. So kernel and recovery have to be combined into one boot.img.
That recoveryPLAY.img, NEVER FLASH IT, alway boot it. If you flash it, it will corrupt your /boot partition.

I can't flash Clockworkmod recovery with ROM manager
I can't flash Clockworkmod recovery with ROM manager.
It says me that I have to install a Clockworkmod based recovery manually.
How can I do it?
As they said u should boot custom kernel (like eg. Doomkernel) to have recovery. I think there is no cwm for play working with stock kernel, or maybe is but it cant be booted.

What's a kernel and what i have to do?
Hi, I've just rooted my Play and installed CWM using this app:
https://play.google.com/store/apps/...251bGwsMSwyLDEsImNvbS5wdnkuQ1dNaW5zdGFsZXIiXQ..
I've installed CWM with no issues (or so the app says) but I can't boot into Recovery. There's an option in the app to reboot into recovery; but all that does it reboot the device normally (except that there's no boot animation). Also tried tapping back continuously during boot and volume down but still nothing.
Is this going to be a kernel issue? If so how should I go about getting the appropriate kernel on my phone?
As the says in description: reboot phone and when it shows sony ericsson logo u should wait for blue led and than start pressing any key an it should boot to recovery

Use the app to install cwm again. It doesn't always take the first time.

Kernel is a part of phone system which is connecting rom with hardware (i think) there is some custom kernels which is usually (always?) prerooted and has builtin recovery. With custom one u can eg. Overclock and/or undervolt ur cpu
U need to find one here on xda and than boot it using fastboot - in kernel's thread should be said how to do it.

you need to flash custom kernel which provide cwm..
flash one of them in fastboot mode.
you can choose doomlord, keiran, cm7, cm9, icx, miui, mjolnir and else
There is an app on the Google Play store called Xperia CWM Auto Installer. It automatically installs CWM.

When i flash a new kernel to my arc, it boots, the new logo appears, but i am unable to enter recovery. When i power on the phone again, the kernel seems to have disappeared as the stock SE logo will appear and it seems like no changes have been made. My bootloader is unlocked and im no .42 baseband

Hi all,
Today I wanted to leave franco's kernel and try something else. I saw that because of the modified ramdisk a special procedure was required. So I did some research and came up with the following. I booted into the bootloader and gave the command fastboot erase boot. Next I took the boot.img from the yakju image from google and gave the command fastboot flash boot boot.img. After that i rebooted fastboot and after that I rebooted my phone. But then my phone hangs at the bootanimation. What did i do wrong? I'm running franco milestone 5 and had to use a nandroid to revert.

Are you running a "stock" rom, cause I'm pretty sure you are suppose to use the boot.img of the rom you flashed before flashing the kernel. I would think something with the default one is conflicting with the custom rom I'm assuming you are running

The problem is that some custom kernels make changes to the system partition as well as the boot partition, so just flashing the stock boot image is not enough. Every time you flash a custom kernel, you should always open up the zip and see what files it's actually changing.

I have been having many issues flashing roms on this phone, the number one issue is that my phone often gets stuck in boot loop after flashing aosp/cm/aokp etc roms. What I figured out is that everytime I reboot the device it will get stuck in boot loop, the only solution is to flash kernel via fastboot quite inconvenient as I do not always have my netbook with me. Perhaps it could have something to do with the update, however I have used the ruu to stock many times and this last time I did not update. Unless the hboot got permanently up dated and using the ruu back to stock doesn't revert back to the old one...
In any case am I the only one having these issues? I really don't mind sense and I love all the cool widgets but I want Jellybean so I would rather not go back to ics.
dude, both the kernels sense and aosp are seperate, only solution is take a backup via cwm or TWRP AND restore it whjen u want
I understand sense kernels are different than aosp, my problem is that after I flash rom+gapps+kernel reboot into fastboot fastboot boot boot.img that phone boots up and all is well except when I reboot as in turn power off then on my phone will bootloop. I was under the impression that once you fastboot boot boot.img you only had to reflash the kernel when you want to flash a new rom. I have to fastboot everytime my phone is shut down.
Also I just did a nandroid back up of stock rom with out flashing kernel in fastboot after using slickkernel(I forget the actual name) from aosp. So it appears that the kernel is only lasting at the intitial boot everything else gets defaulted to stock kernel.

ok try this, download sick kernel fastboot it, the flash the image via cwm
I figured out my own mistake, I was using fastboot boot boot.img which does not flash the kernel but is more of a test drive. So I now did this and all is right with the world fastboot flash boot boot.img. I do not have a lot of experience with fastboot or bootloaders. Sorry to clutter the Q&A
Ohhhh lol good

Here are the steps
*Download rom, gapps, kernel
*in recovery factory reset, wipe system ( optional)
*install ROM, gapps, kernel
*reboot into boot loader(hboot)
*Mount USB and extract boot.IMG from ROM and put it in c:/Android
*make sure phone days fastboot, if not press power button
*open up adb
*CD c:/Android
*fastboot flash boot boot.img
*restart phone and out sticks
Important part is to add flash to the fastboot commands

After flashing a new ROM my phone will only boot properly using "c:\fastboot fastboot boot boot.img" on the PC .... If I boot holding the power button the HTC screen saying "This build is not for ...." loops.
Does anyone has a solution to this?
Did you flash the right kernel? Your command seems wrong.. It's fastboot flash boot boot.img, not fastboot boot boot.img
