[Q] unlock sim and bootloader on xperia play

Hi.I'm going to buy an italian xperia play branded TIM.
My question is:Can I flash a general firmware to debrand the phone and than unlock the bootloader with fastboot?
Can someone explain me how to do these things?
Thanks very much

Think the 1st sticky thread at the top of this forum should answer all your questions!

well.
my last question.
If i buy a branded xperia,can I flash a general stock firmware non branded after i installerd Clockworkmod for locked bootloader?and next,unlock bootloader and flash doomkernel?

A better way to do that is just to not flash the CWM for locked bootloaders. The reason being that doomlords kernel includes CWM in it already, I'm not sure how the locked version is stored or whatever but you might run into problems if you have both "installed".

So there is a Doomlords kernel for locked bootloaders? mmm..this is a good news.In fact i wanted to flash CWM first because i thought that i have to unbrand my xperia and than flash another kernel.So i can buy xperia branded and install doomkernel? or i have to:
by xperia-install CWM-unbrand Tim-Unlock bootloader-remove CWM-install doomkernel? excuse me for noob

easiest way to debrand your phone: search Wotanserver on google and use their software to debrand (really esay, there's a step by step guide), then do whatever you want...

No, how it works is you have to unlock your bootloader in order to flash a kernel. As for unbranding you can either use the Wotan server or a .ftf file, neither of these require an unlocked bootloader. You can also flash CWM with a locked bootloader, however this is not the one included in doomkernel, and it will not grant you the ability to flash ROMs as you need an unlocked bootloader to flash the kernel. You want to touch the kernel? You need to unlock your bootloader. Unbranding? You can simply use the two methods listed above. All I was saying earlier is that if you plan on getting your bootloader unlocked (which in most cases is going to run you $24) theres no need to install the locked bootloader CWM first as once youre unlocked you can just flash doomkernel and already have CWM installed.

ok thanks.i heard that the italian xperia and not the verizon ones can be unlocked with an official method released by sony

Yep thats true, it's the case with a lot of r800i's, if you can put your phone into fastboot mode (turn off, hold search button, plug into usb, blue light comes on) you can unlock it for free through sonys online tool. While the light will go on for the CDMA version you don't have an IMEI to enter on the site so it wont work. All other plays CAN be unlocked, but its not free, you need to go through a pay service to enable fastboot.

Very thanks!however one of my friends bought an xperia and it was GSM R800i TIM and he was able to debrand and unlock so i think that also i can unlock my future xperia,or almost i hope it

Ya it all depends on where you get it from, but keep in mind it only costs $24 to unlock, so even if you find one say on eBay thats cheap but locked to a carrier, you could still just pay $24. That being said they're going pretty cheap now so I don't think you'll have a problem finding one, unlocked or otherwise. As a side not though, you don't need to be unlocked to debrand the phone, you just flash a different firmware file .

and so i can flash a generic firmware with flashtool or similiar?without installing CWM for loocked bootloaders?that's simply excellent!It's can't be better Ok,i will buy an xperia play and not lg optimus dual,that i simply hate xD i don't want a super-power phone,with a bad designe and without the pad.i loved,i love and i will love pad in gaming

Yep you can flash firmware, install CWM, and root, all without unlocking the bootloader (not that you need one to do the others). Unfortunatly the more fun stuff does require an unlocked bootloader, ie overclocking, undervolting, custom ROMs, etc. Anyway you always have the option, so read up on it and decide if you need it or not, regardless, enjoy your new toy

[Q] r800at, locked BL, rooted, stock 2.3.3, need help with custom roms

i have tried to flash/install custom roms that use the stock kernal, but none of them didnt result in a bootloop. are there any roms that would or could work for me? any help would be nice. semi-noob.
xperia play r800at (at&t)
rooted stock 2.3.3
locked BL
(also, if there is any free way to unlock sim network, let me know)

Don't know about customs roms so I'll wait with you for an answer. But as for unlocking the sim network. It's pretty cheap. It cost me $7USD to unlock it. Don't know if that's any help since that's not the question you asked.

to my understanding u have to unlock the bootloader in order to flash a custom rom. I just had my r800at unlocked by a guy from xda. I have ICS running on my r800at as we speak and i love it.

How do you get out of the bootloop?
This is my first r800at, and after several sammys and htc, I found flashtool message "Error flashing. Aborted" a little short on feedback

Upgrading from .42 to .62

I have a UK Xperia Play on .42 firmware with CWM recovery and root provided by Zerg Rush.
I've heard that I need .62 to install some of the custom firmwares.
.42 appears to be the latest firmware I can get OTA. I'm not sure the best way to upgrade to .62, do I need to go via .58 or similar.
Does it matter that I have a UK phone?
Is it possible to preserve my settings?
Will I need to re-root at any time?
In the long run I am looking to install DooMKerneL and probably something like Jokawild.

You have to flash the ftf file for your phone
Here is a link to 99% of them

If you install a new firmwares. Maybe you'll need to root it again..
But since the devs makes the pre-rooted custom ROMs, you don't need to root it anymore

I don't have an unlocked bootloader. Is this required to install a custom ROM even if I have root?
Is there any disadvantage to unlocking the bootloader?

No unlocked bootloader = no custom kernels/ very limited to roms
Only disadvantage is it voids your warranty, but being that you have root, you have no warranty anyway lol

I was in the same position as you. I wanted to get a custom ROM and be able to overclock my phone. After a few annoying errors, I finally got it up and running
Basically, your going to have get your phone into flashmode and then flash the .62.ftf file on your phone. Congratualtions you now have .62FW (although youve lost root).
To get root on .62 FW, your going to have to flash a custom kernel (I did DoomKernel v14). To flash a kernel, your going to have to unlock your bootloader. After unlocking and flashing the kernal, your phone is now rooted.
And plus the positive side Ive heard is that you CANNOT brick your sony eircsson phone. (well you probably could but there is a very very slim chance of that happening).

Thanks.
It seems I can't unlock via the regular Sony way as Unlock Bootloader is set to no.
I think I need S1Tool or something similar (maybe something I have to pay for) to get my bootloader unlocked. I'll check the forums a bit before I ask any questions that haven't been asked before

i did it via omnius and it work great, i just payed 19.76 for one single unlock credit on gsmserver

not sure why people say that root voids warranty.
i have ATT play 4g and it was having hardware issues, so i flashed the stock ATT software back and took it to the store. i got a "new" one in the mail two days ago.

I also sent my rooted xperia play that had the slider broken to CLARO El Salvador and they repaired it (They flashed their ROM again XD)
Now i have unlocked bootloader but who cares i have premium insurance

Any modification to the software voids the warranty..

Update:
I downloaded s1tool and connected the test point to the ground. Everything seems to have worked so I am guessing my bootloader is unlocked. Is there anyway I can verify this, or should I just attempt to install a kernel?

Try to put the phone in flash mode (green light) if it recognizes it, it's unlocked. I think there is a sequence or symbols/numbers you can do to check it, but idk what that is since im a r800x

To check your unlocked bootloader you need to dial: *#*#7378423#*#* , then go under, Service info > Configuration > Bootloader unlock allowed: Yes/No.

Problem with Recovery Mode

Hello,
I have a Sony Ericsson Xperia Play and I'm starting in the android world, I've read a lot here on the forum already informed me about what I do to boost my smartphone, I wanted to install a new ROM, and follow what the most part of the posts say, I started by installing the most current Baseband, do Root (all this through FlashTool), install the X-Parts, put the CWM for Stock GB, but when I restart in recovery mode it always starts in normal mode, never enters the recovery, nor with the selection keys or through the X-Parts.
The Smartphone has a locked bootloader, and did what they say on the website that Sony only in internal settings says that this smartphone is not entitled to have the bootloader unlocked.
Can you tell me what I'm doing wrong? Or if there is no solution without the Bootloader Unlocked?
Thank you for availability
Best regards,
Cristóvão Guerra

Search for xparts on here and download one of the older versions. For some reason xparts v5 from the play market doesn't work. Also what version of Xperia play do you have? R800x (Verizon) or do you have GSM version and if it says you can't unlock boot loader you'll have to pay 20 dollars to get it unlocked from an unlock site. Also you can install stock based roms while you're bootloader is locked if you donf want to pay to unlock it.
Please press thanks if I helped.

Do what abdel12345 said for the CWM. If you have an r800x Xperia Play it is unlockable i think. My phone said it couldn't be unlocked either but when i went through the steps i came out with an unlocked bootloader so i think verizon just wants to trick the r800x users.

i have a R800i, v. 2.3.4, baseband 4.0.2.A.0.58, so can you tell me who I have to talk to unlock the bootloader?

Also, for recovery, try using version 5 of X-Parts. The later versions don't seem to work

flashing or installing kernels on locked bootloader help ?

Ok my bootloader is locked, my phone is the At&T xperia play. I rooted my phone recently and found out that my bootloader was locked and couldn't be unlocked on the service info on the phone. I recently used x-parts by pvyParts, and that helped me a lot with putting Aurora play 1.0.1 rom on my locked xperia play. I really want to install lupus kernel on my phone for gaming is it possible for me to install a kernel though though x parts on the CWM recovery menu ?

Dont spread misinformation! R800at cant be unlocked for free from SONY. The only way to unlock R800at version is to pay for the bootloader unlock.
