[Q] How to reboot into recovery mode?

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.

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'm so glad I found this post. It was really useful. Also felt good using the search and actually finding what I need.

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.

Booting Into Recovery

Right, I've got an Xperia Arc Lt15i. Its rooted but got a locked bootloader. Its running 2.3.4, a custom rom (think it's Aniking) and I haven't done anything to the kernel. I put clockwork mod on it a few months ago so i could get the custom rom. Now I want to go back into recovery mode, go back to the stock rom, through a nandroid backup, and update to the official ICS, since it only just came out for my phone. I am now unable to boot into recovery, having tried spamming the volume down or back buttons as well as using apps that say they'll reboot into recovery. Nothing works, the phone always boots normally. I'm sure clockworkmod is on there, i never took it off and have tried installing it again with x-parts to make sure. I clicked the Nandroid Backup option in X-parts - it managed to boot into recovery but went straight into doing the backup and then immediately rebooted. I'm not too good with doing it all on the PC so haven't tried or understood any of that.
Also, a question that might be easier: is it possible to just update to the official sony ICS with that PC companion program from a custom gingerbread rom or do I need a stock rom.
Any help greatly appreciated. Thanks

you can just flash ICS from a custom gb rom since it doesnt require an unlocked bootloader, but yeh you can use PCC
since your on stock kernel and have flashed a rom i think it resets it to not having CWM (on stock only i think) just re-install CWM on your arc and it should fix everything

Just install the Recovery again. By default, it is installed in system folder, where the whole ROM is and usually is formatted before flashing.

since your bootloader is still unlock, just use pc companion and update your device from there you'll have ICS on stock

I have the same problem.
I installed CWM recovery on my rooted arc with locked BL using x-Parts and successfully used it to install a ROM. I was going to try flashing some mods but I cannot get back into the recovery even after re-installing it with x-Parts v5 and v7, the phone always boots normally.

Try and boot into recovery using cwm app after reinstall.

Xperia S wont load! HELP!

i decided to unlock my bootloader on my already rooted phone to try out some new JB roms. I installed Sspeed kernel and RecoverX which was fine then I followed the instruction to install the latest PACman rom by wiping all the caches and the system in recovery before flashing the rom. Problem is I accidentally left out the flashing and went straight to reboot phone. NOW THE PHONE WILL NOT GO PAST BOOTLOADER ANIMATION.
I tried using flashtool to flash stock rom. The phone is connected in fastboot mode but will not flash! PLEASE HELP!
Many thanks in advance!:fingers-crossed:

To flash stock rom you need to be in a flashmode, not fastboot.

Ive done that few times just install any kernel via fastboot, then you will be able to go to recovery its just that recovery is kept in system partition, so you wiped all the system and recovery flash any kernel that has recovery build in, and you will be good to go

Little help about custom roms

Here is my problem:
I was playing with my brother's Arc S and the things I done are that I downgraded to 462 from 587, rooted it, gone back to 587.
After that I flashed via X-Parts CWM 5. I downloaded Xperia Ultimate HD, I booted it in recovery but something was not OK. Couldn't go to recovery mode with Power + Vol down, so I gone back to X-Parts and pressed reboot in recovery mode. I flashed the rom and after that it bricked..
Couldn't do anything so I restored it with Sony Update Service. I need help how to flash that rom without bricking the device again? I have SGS3 and it is pretty simplier that this..
EDIT: Forgot to say that I tried to unlock the bootloader but it told me that it is already unlocked.

Before installing the Rom zip, what did you do inside the cwm?

Then you don't need X-Parts, just flash a kernel with CWM.

after installing cwm recovery have problem

I can't seem to find a answer for this problem. I have an xperia zl C6506 which I have unlocked bootloader and also have rooted. My problem is that I try to install cwm recovery which I can but after I do that I can get into recovery but cannot bot into stock. I then have to go in and use flashtool to kernel so I can boot again but then can't get into cwm recovery again. Need help read everything I can and tried more then once to install cwm recovery but always have same issue. Hopefully someone can help me with this because can't install custom rom. Did I miss something please help.

Sounds like the recovery you're installing isn't compatible with ROM? what ROM are you using and what kernel/recovery specifically? Are you using doomkernel? Because doomkernel comes with both TWRP and CWM and I know it works with stock. If you're not using stock, then Meow kernel?

Make sure you're using v17r1 http://forum.xda-developers.com/showthread.php?t=2405925

Ok I did the v17r1 and now when it boots up it shows doomlord kernael and then continues to boot up to operating system. How do I get into recovery?

press volume button while LED is i think purple? or orange? Once it lights up with a color, press a volume button, it'll change color a second later then boot into recovery.

Thanks for all your help worked like a champ. Tried it power up CWM recovery and power down TWRP recovery. Again thanks much the xperia zl is very different from all the other android smartphones I have had.

One other question I now have after installing the custom recovery is my Wi-Fi is no longer available. The doomlord kernel has made it non-usable. Any clues on how to fix this issue? I'm sorry for asking so many questions but like I said new to xperia zl.
I figured it out after I installed the doomlord kernel I then went back into CWM recovery and installed the whole zip file everything works. Any way thanks for your help without it I would have never been able to flash a rom. I'm now a very happy camper.

Do you mind helping me out i have the same problem as you. I am not sure where to put the files that are in the v17 zip. when i open them i see 3 folders and a boot.img. i have been using the flash tool up until this point. I am rooted and my bootloader is unlocked. I am just not sure how to flash the kernel so that i can get some type of recovery on y c6506 . any help would be helpful. I did a search and found this
[ how to install my kernel ] (via fastboot)
download the kernel package update.zip......i did this
save it on c:\ and extract the boot.img from the package....not sure what that means. does it just mean drag it to my deck top or something
save the boot.img to the folder containing fastboot binary....where is this folder?
flash the boot.img using fastboot:... i can use flash tool for this but when i click the lighting i check fastboot instead of flash
like i said any help would be great. And I will thank you
