[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.

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'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.

[Solved] Stuck in CWM Recovery

During installation of ARHD Rom I suddenly got caught up in CWM Recovery mode. I have now tried to wipe system and everything and do a "restore" of my NANDROID backup without success. My question then is; how the hell can I push a ROM to my phone with the phone only in CWM Recovery??? I'm kind'a desparate!!!
Can also mention I'm on a Mac!
Hope someone has the answer!

Try restoring your nandroid backup, just remember to flash the boot.img
Sent from my fauxed HOX running ARHD 8.0.0

Did you flash recovery to the boot partition? (fastboot flash boot recovery.img)That could explain why it only boots to recovery. Try flashing recovery again (fastboot flash recovery recovery.img.) then the boot.IMG (fastboot flash boot boot.IMG )then the Rom.

I've already tried that, I've even tried going to advanced restore -> boot -> restore boot without success..
BTW; I've now managed to push a new ROM onto my phone, installed it but still it won't but other than to recovery!!!

Sounds pretty much like what I did.. Will try your version now..
LATEST EDIT:
Seems like it did the trick rayford85.. Nice to see the bootanimation on my HOX again! Stupid step to forget (flashing the boot.img) LoL! Thank you rayford85!

Reusing this post to another dumb question... Everytime I reboot my phone it seems like the boot.img disappears because I have to ./fastboot-mac boot boot.img for every reboot of my phone!
Any good ideas of how to solve this?

It's flash boot.img not boot boot.img

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

[Q] Restoring

Before i even root my rom i made a backup..And i root mycphone i put custom rom (including flashong custom boot.img cm10.1) and now i want to restore my backup..And now is the question..I must flash stock boot.img or just restore device without flashin another boot.img?
Sent from my HTC One X using xda premium

You need to flash the boot.img that is located inside the backup folder, then a full wipe in recovery and restore the nandroid

And if you are asking this because you want to update to JB you also need to flash back the stock recovery afterwards . The phone won't update on a custom recovery

[Q] From Stock to Custom

Here is the phone I have:
My Current Phone: Sony Ericsson XPeria Play
Model: R800i
ROM: Stock GB 2.3.4 (at the moment)
Kernel: Stock 2.6.32.9-perf
Build: 4.0.2.A.0.58
It's un-branded phone that I got via eBay from a seller in Hong Kong.
I wasn't sure if the bootloader was locked or not so I followed the steps to unlock and got back that it was already unlocked.
I would like to install a custom ROM, but the 1st issue is that I can't install a custom recovery via X-Parts for some reason, I install the app, run it and click the install CWM and the app states that it installed OK but if I try to reboot to recovery via the app or via pressing any button on the phone while booting it just won't load the recovery. Any Ideas?
The only reason I want to install the custom recovery is to backup my current stock setup, but if there is a way to return to stock without need of a nandriod backup of the stock ROM then I can skip this part since I use Titanium Backup.
having said that, what would be the steps to follow to go from the Stock ROM I have to install a custom GB, ICS or JB ROM? (if there are any differences)

In case you want to return on your. 58 firmware, you can search for the .ftf of that firmware (just google it, or go under smokerman's roms and firmwares list under development section), download and flash it via flashtool, and your phone will be resetted to the original setup.
During this process, you will loose your data (so your apps and your apps' data), but if you have titanium backups, then you're good to go
Just search on the web if you dunno about flashtool yet

Thanks CriGiu (also pressed the Thanks Button BTW) Now I know what to do if I want to return to the stock ROM... now what would be the steps to follow to go from Stock to Cutsom... would these be the correct steps?
1.- Flash a Custom FTF via Flashtool
2.- Flash a Custom Kernel via Fastboot
3.- Flash a Custom ROM via Custom Recovery
Is this correct or am I missing something?

Yup, and you should flash .79 firmware at the first step, in order to have some of the latest features, like the ability to have custom partitions layout (needed by kernels like Lupus Kernel by wedgess, or Turbo Kernel by Cosmic_Dan).
And another thing you should do is to wipe system and data via fastboot after you flashed the kernel, using:
fastboot erase system
fastboot erase userdata
This is needed if you wanna try kernels with custom partitions, or you'll be not able to boot into the rom, or the cwm itself

Remember those steps, it's alpha and omega in Play's flashing :silly:
You don't have to do all 5 step all the time, usually you'll flash ftf firmware file only once, you'll wipe system and data if you flash kernel with different partition layout, and most of the time step 5 is needed to flash custom roms
Just keep in mind that kernels can be only for certain type of roms (gb stock, ics stock, aosp, cm7, cm9 muiu type of roms)
Best way to know wich kernel to flash is to read ROM thread and see what recommended kernel is.

OK I have installed CM10 MaXeD but it reads "4. Install touchpad fix( GSM ONLY)" my phone is GSM but I can't locate this fix? anyone has a link to this fix?
