[Q] How to boot to recovery?

Hey peeps - another annoying n00b question (sorry)
I have the Doom v3 kernel and stock 2.3.3
Just want to know how I can boot into recovery so I can install a ROM zip?
I have tried every combination of buttons on startup including Power then tapping and holding Back and I cant get into recovery mode.
Please help i really want to try the GingerStation rom

Turn device off. When off press the power button once, then start tapping any hardware button untill device boots into recovery. You can also try doomlords xCharge app from the market.
Sorry i havent been very active in the forums recently. I will be updating rom soon with some cool features and a new name

AFAIK you have to boot into recovery the standard way. Like the person above described. Once you do that CWM creates a directory in /cache called "recovery" then xCharge works fine

OmG it worked.. thanks alot guys!!

Did you try everything from this thread?
eg. Pushing back/wolume button (or maybe other) when the led lights.
If yes. Try get to it using command or reflash boot.img

Are you rooted?
If not, do you know how to do that?

No, it's completely stock, I've read I have to flash a file in recovery, I've got it, but I don't know how to reboot in recovery with button combination.

To get cwm, root using doomlords easy toolkit, search development
Then install this app and click install: https://play.google.com/store/apps/details?id=com.pvy.CWMinstaler
After you have installed that, boot on your phone, and when you see the sony ericsson screen, repeatedly tap volume down until you get into cwm

WOW! It's very easy this way, thanks a lot
Another quick question, now bootloader is unlocked?
Can I flash any custom roms like any other device? (flash in recovery mode)
Thanks again.

That way i showed is to install CWM with a LOCKED bootloader.
This will allow you to flash STOCK based roms, no others
This is not unlocking bootloader, just getting CWM
If you want to unlock your bootloader, you have to go to the sony website or pay to unlock it

Oh, so I can't flash CM roms, but I can with stock based, right?
I knew about Sony website, but I though there was other ways to have the bootloader unlocked.
Well, thank you a lot, now I have to find a good stock based rom.

He's asking for GB root. Root method is different on GB than ICS, therefore those instructions won't help him.

Thanks for this, i have now rooted which was a complete pain to do phone just kept on saying no. Now i am having problem with ROM manager/project x
trying to install ultimate hd 2.0.3, rom manager first loads to a point i can hardly read it and when i go to flash it says unsupported device so i installed it via project x install finished rebooted and phone, turned back on like normal and not into recovery mode, does this mean i have to unlock the bootloader
please help but i am liking the root requirement apps though
p.s Do i have to update the kernel if i want to try Xperia Ultimate HD because one person says about it for unlocked and doesn't mention it for locked bootloaders

Flashtool
Try flashing a stock firmware in Flashtool, good luck.

Now downloading the stock firmware using sony update service, will update about the situation when it is done

Update Service with an unlocked bootloader is a bad idea.

Try this.
http://developer.sonymobile.com/services/flash-tool/how-to-download-and-install-the-flash-tool/
Official flashtool to go back to stock rom.
And as the guy above told you, SEUS on unlocked bootloader is a bad thing.

Hi. I have same problem.
Just flashed FreeXperia rom and gapps. Phone wont to power up. Just geting blue led or green.
Any clue? My bootloader is locked.
tried to use official xperia update tool but it wont to recognise my phone (maybe i doing sth wrong :/)

Dude,
As the others have said you cannot install FXP CM10 on a device with a locked bootloader.
As such your device will not boot, your options are to either.
1) use flashtool to flash a stock rom - instuctions how to use flashtool can be found on the forum
2) use Sony update service to flash back to stock - This is the easier option, but all your data will be wiped.
Once the device will boot up, if you still want to use FXP roms then unlock the bootloader first, or try a rom for locked bootloaders.
Either of the above should work for you.

yea phone works again fine on the stock

At least you show others, do not flash custom ROM if it's only for unlocked bootloader.
If you have locked bootloader you can't flash custom kernel and you will stuck in bootloop.

[Q] Want to root and install R800a, very lost.

Hi guys, as the title said, I want to root my new Xperia Play R800a, and I am very lost right now. Ultimately, my goal is to install Xperia NXT 2r1. I think that since I have the r800a version, I am not able unlock the bootloader, so I am ok with not having a custom kernel.
But the problem is, I'm totally lost right now. Could anyone show me a guide or something to what I'm supposed to do to start? That's all I'm asking.
What I HAVE done is downloaded everything they asked for me to download in the post, and have installed flashtools, but whenever I try flashing the firmware 4.0.2 enhanced, I am not able to do so. It is just stuck on a screen where it tells me to go to fastboot mode, but I go to fastboot mode, and for some reason it isn't recognized. (I know it's fastboot because the power button is glowing blue.) I think a driver might be installed incorrectly, but I'm not sure how to install it correctly after.
I'm sorry if my post isn't that helpful, I'll add any more information if you guys want me too.
Thanks in advance.

Sorry for the late response -
I flashed Firmware 4.0.2.A.0.58 Enhanced, the one that they told me to flash in the guide.
I did notice however, that it said that it was for r800i. I just assumed it was universal. Is there a specific firmware I should be flashing for r800a?

I went to that link and downloaded and flashed R800a_4.0.2.A.0.79.ftfwith vendor partition NEWEST FTF, but the same thing happens when I try to root. It's like the button is unresponsive. Is there a specific ftf I was supposed to flash?

Alright found out the problem. Apparently there are two versions of flashtool. One version doesn't work while the other does. I honestly don't know what the difference is. But for other people who might be facing the same problem, if your flashtool has only three icons, Flash, Root, and check for SU permissions I think (it looks like a key), then you have the wrong version. Your flashtool should have 7 icons.

Doesn't Matter

Oh yes, I found that out a bit later. The problem was lying in the flashtools I was using. Once I got the right flashtools, I reflashed the previous firmware rooted it, installed the rom, and it all worked perfectly.

[Q] Need help - ROM issue - phone restarts at boot animation

I am not an expert in this area. I just wanted to get rid of bloatware from my Xperia Arc (2011 edition). So I followed the procedure given here
http : // talk.sonymobile com/thread/97327 (basically unlocked boot-loader, and flashed using another firmware to get root access).
The phone was working well for 2 months. One day I turned on Bluetooth and phone crashed. Now it starts and at the boot animation restarts. I gave it to service center but they said they will not repair because of some policy.
Please suggest a solution to this. (I have USB debugging enabled already on it).

Reflash stock firmware. Its a known bug.
If u have recovery installed boot into it. Wipe cache and dalvik and reboot. Phone will boot to system

I will check if this mobile has recovery installed into it. Where can I get stock firmware? Sorry I am really new to this stuff.

If you Google "xperia arc s 4.1.0.b.587 ftf" or something in Google you'll get results. The stock ROM is somewhere in the dev section too, use the search button, I'm on my new phone and search works weird here.
I assume since you unlocked BL you have drivers for your device.. In this case use flashtool, click on the lightning icon, navigate to your firmware file and connect phone in flash mode (menu + USB cable I think, I have not used my arc for some time but it should give you green LED if you done correctly), flashing will automatically start

Flashtool will work regardless of the bootloader status.

Keep calm mate and you will sort it out.
use this thread for your stock ftf files and use the flashtool.
After that make sure you have got the correct kernel for the rom which you choose and always backup your system using recovery.
