can someone help me?

i have an att xperia play with a locked bootloader...i have used superoneclick to root it
and i was wondering what i need to do to unlock the bootloader
or install a custom rom without unlocking the bootloader.
i tried installing an app that put cwm in the sys app i believe and tried flashing a rom that way but i got stuck at the SE screen. i had to use the SE update to "unbrick" my phone.
im kinda nervious about doing anything more on this phone till i know what i am doing.

Unfortunately if you're on AT&T youre sim locked so to unlock the bootloader you have to go through a pay service like this (~$24):
http://forum.xda-developers.com/showthread.php?t=1322827
If you unlock your bootloader you can run custom kernels, meaning you can run CM7, MIUI and any other ROM that requires one. Without unlocking your bootloader you can still install CWM and flash ROMs. The only restriction is that they must be stock based, meaning they use a stock kernel. Without unlocking you can't use fastboot, and without fastboot you can't flash custom kernels.

So how would I install cwm without unlocking the overloaded?

Use CWM Installer. Of course you'll need to be rooted first

That'd the app I used before to install a Rom and got stuck on the SE logo. So how would I know what Rom I can use with this and a locked bootloader?
Thanks for all the help so far

Basically any one that says its for locked bootloaders, because they will say that, you just have to read it over very carefully. He's a couple examples of what you'll see:
This is for UNLOCKED ONLY:
http://forum.xda-developers.com/showthread.php?t=1431608
If you scroll down to how to install you'll see he mentions the kernel and flashing the kernel through fastboot. You can't do this on a locked bootloader, you can potentially brick your phone if you try anyway.
This is for unlocked or LOCKED:
http://forum.xda-developers.com/showthread.php?t=1485931
As you can see they specifically say its for locked and unlocked bootloaders, note how there is no provided kernel or mention of fastboot. Its simply a mod of a stock firmware, not built from the ground up like unlocked bootloader ROMs.
*EDIT*
Here's an incomplete list of ROMs to use on a locked bootloader, look under stock based ROMs
http://forum.xda-developers.com/showthread.php?t=1294129
That being said still make sure you read the fine print to see if it requires flashing a kernel.

Thanks ill give it a try

becaful on dead boot.
just a advice, if you try to unlock bootloader with third party software. be sure you know what you are doing it. else, it will brick your phone easily.
1. you need to root you phone using x10 flashing tool version 0.6.6 by Bin4ry & Androxde. just one click to root your device.
2. try on sony developer site to unlock your bootloader. web add=unlockbootloader.sonyericsson.com/instructions
3. follow the instruction there you will get thing done. but... please read the instruction cafully. be sure you know what you are doing it.

[GUIDE][ARC/S][WALKMAN][LOCKED BL]Get SenseME Info (Download music info) working

Managed to get Download Music Info on my Xperia arc S with UNLOCKED bootloader, running a custom ROM.
Requirements:
Xperia arc/Xperia arc S (only tested on arc S though)
Android ICS 4.0.4
Walkman app - get it from http://forum.xda-developers.com/showthread.php?t=1726322 (many colour variants) or http://forum.xda-developers.com/showthread.php?t=1681250 (for Beats MOD)
Flashtool - get it from http://forum.xda-developers.com/showthread.php?t=920746
Stock ICS Kernel for rooting - found in ZIP attached
Relock bootloader file - found in Zip attached
Before starting, unzip the two FTF files in the attached ZIP to your local Flashtool folder, under 'firmwares'.
Instructions:
1) Flash your ROM (must be ICS, custom ROMS are fine) on your device - either via CWM or Flashtool.
2) Install Walkman (using the two links above) - NOTE: Ignore this if you have one in your ROM and you are satisfied with it.
3) Boot your phone into FLASH mode. (Shut your phone down, hold the BACK key while plugging it into your computer)
4) Open Flashtool and click on the FLASH icon (lightning shape), select 'Flashmode' and click OK. Then select the firmware with Device lt18i, Version 4.1.B.0.431, Branding ready to root. There should be only two files on the right, loader.sin and kernel.sin . Click OK. (Don't check any boxes!)
5) Wait for the flashing to complete... and you're done! Your phone should be able to boot properly, and Walkman Download Music Info should work.
Warning:
If you would like to have CWM/root even after locking up the bootloader, MAKE SURE you have a PRE-ROOTED ROM! Then you can install CWM via Market apps such as X-Parts and so on.
Hit Thanks if I have helped you! Sorry but I'm new to XDA-developers, so maybe I'm doing this wrongly, I dunno...

This is great! :victory: but can it work for stock .587 kernel?

I'm not sure, I didn't try. But I don't think so, since the kernel is for .431 Build. Sorry!

[REF][Guide] Bootloader/Root + FAQ

Glossary
Post 1 FAQ
Post 2 Guides + after rooting
FAQ A.K.A The Basics
What is root?
Root is basically being able to run as a superuser in linux or admin in windows, giving you the ability to go deeper into the file system. It is a pre-requisite for most tweaks.
WTF is bootloader locked/unlocked?
For many people root is enough. However, if you want to change your kernel (for overclock etc.), try leaked builds or have a taste of custom roms such as Cyanogen Mod by FXP, you must unlock the bootloader.
What are ftf files?
They are essentially firmware files. They can be flashed with flashtool, and are used for recovering from a bad flash or getting updates from other regions.
List of ftfs can be found here.
Will be constantly updated.

The guides
Unlocking the bootloader
WARNING: You will lose Bravia Engine 2 for photos FOREVER! Before you start, do a full backup of your phone data with backup and restore app. Remember to take out the SD card after backup or you will LOSE ALL DATA. Unlocking the bootloader WIPES THE INTERNAL MEMORY (and SD CARD if you don’t TAKE IT OUT). YOU HAVE BEEN WARNED!!
First check if your bootloader can be unlocked. Type *#*#7378423#*#* and click service info. If it says bootloader unlockable, you may proceed to unlock it.
Follow Doomlord’s excellent guide here. Feel free to ask questions if in doubt.
Relocking the bootloader
If you want to use PC Companion or Sony Update Service to update your phone, you must relock the bootloader. Follow this thread by alivanov79.
Rooting the phone
DooMLoRD Easy Rooting Toolkit (the very easy way)
1. Follow DooMLoRD's guide here. It's that simple.
Flashing kernels (unlocked bootloaders)
1. Download Superuser zip and place it in the sd card.
2. Install flashtool from HERE.
3. Open up flashtool and select fastboot option by clicking the lightning icon.
4. Turn off your phone and hold the volume up button while plugging in the usb cable.
5. Download Kernel with CWM.
6. Select the kernel you downloaded in flashtool.
7. When the phone restarts, continuously press the volume up key.
8. You should end up in the recovery. Use volume keys to move up and down while using the power button to click.
9. Choose install zip from sdcard >> choose zip from external sd card >> navigate to the superuser zip you downloaded earlier.
10 .Reboot and you are done!
The After Root Guide
First of all, congrats on making it this far. You have proven to yourself to be a daring and adventurous individual. :victory:
Moving app data to SD card
1. Install DirectoryBind here. Choose the latest in alphabetical order.
2. Open up your game and install the data on internal memory. (skip this step if you have already done so)
3. Use a file explorer to create a new folder in your external SD card. Name it "Game data" or whatever.
4. Copy your whole game folder(eg. com.ea.games.nfs13_row ) to the folder you created on your external SD card, eg."Game data". You can use a computer if you want to. Remove the files inside the game folder in the internal memory but leave the game folder intact.
5. Open DirectoryBind and grant superuser permissions.
6. Add new entry by clicking the settings button, a.k.a the 3 dots at the bottom right.
7. Hold on the box for data path and point it towards game data in the "Game data" folder.
8. Hold on the box for target path and link it to the empty folder in internal memory.
9. Do not check the "Transfer files" option.
10. Click add.
11. Turn on the button beside Root Access OK. It mounts the game data at boot.
12. Click settings >> more >> backup database
13. Done!

Are you even serious? BE2 is a big Deal!! without it, your screen would just be a regular low end device screen. The fact that our SP's screen is already inferior to S3's super amoled, and you will still remove the bravia engine? what's wrong with you man. Don't encourage people here to lose their bravia engine.
Guys lets wait for a proper root. It will come. just be patient.

You lose ONLY for photos, not for videos. It's NOT a big deal, since it oversaturates the photos anyway.
I actually prefer it this way, but unlike you, I respect other people's opinions.

If we re-flash the rom, can we use BE2 again?!

Sorry if my post offended you, what im just trying to say is, not everyone wants to lose their BE2, if it's cool with you then its fine, for everyone else I suggest wait a little bit more. here's a bit of infro from GSMarena btw:
From GSMArena: http://www.gsmarena.com/sony_xperia_sp-review-924p3.php
The TFT screen is backed by the Mobile BRAVIA Engine 2, which enhances contrast and sharpness, brings down noise and saturates colors to make them more pleasing to the eye. The reds in particular tend to really pop out.
The contrast is only average and colors are hardly the best around. Brightness levels are pretty decent, though.

AFAIK, you need to backup your TA, before you unlock your bootloader so you can restore it afterwards. Saw it on ZL's forum before. SP's forum is a bit empty, not much info and instructions on tinkering with our device. Im still waiting though

When purchased the phone in india in 1st week of may...when i checked the status of bootloader unlock allowed it said Yes. However, there was a s/w update to the firmware .211 after the update when today i saw the status it says bootloader unlock allowed No...do you think after the firmware upgrade they disabled this option????

I guess No.
Did you try any script available for root of other devices in our Xperia SP device. Cause i tried it, which end up in bootloader unlock allowed status to No. After that I reflash the stock firmware using Sony Update service, then I got back to the normal status bootloader unlock allowed status to Yes.

you can only lose your TA partition if you unlock your bootloader, flashing a firmware ftf file does not touch that. please search and read the available threads on how to flash a firmware file and what you can and cannot check, the only things that people sometimes uncheck is wipe data, cache etc

When ive flashed ftf files, i have never checked anything in the exclude section of the flash tool, leave that as it is.
There are 2 versions of flashtool, one is an official from Sony, this tool does not have the option and can only be used with a unlocked bootloader. The flashtool that can be found here in the forum can be used wether you have unlocked or not, it was originally designed back when the Sony Ericsson Xperia X10 came out.
So to conclude
1. Make sure you have the latest version of flashtool installed.
2. Download your preferred firmware.
3. Open flashtool and click the lightning icon at top left.
4. make sure bootmode selected is Flashmode.
5. Select your firmware file when prompted.
6. Flashtool will now process the file (give it a minute or 2 to do this)
7. It will now prompt for you to connect phone in flash mode.
8. make sure your phone is turned off, in order to connect in flash mode while holding volume down
connect the usb, keep everything held down until the flash starts.
9. Follow onscreen instructions, it will take around 5 minutes for this to flash, flashtool will tell you went to
disconnect and reboot.

Or just wait for a root exploit to show up for the latest version. I mean unless you're planning to flash CyanogenMod or something now then why worry about it?

Here you can learn more about the flash tool for Xperia™ devices, which is a desktop application that you can use to flash Sony software on your unlocked Xperia™ device.

Do not touch the bootloader at the moment, there is a reason why people are not unlocking their bootloader as doing this breaks camera functionality. Don't be scared, it is quite a simple procedure.

Flashing with flash tool will NOT break your phone and you can airways force a repair with pccompanion.
Just try it, it's perfectly safe

New Samsungs are worse, you can't restore them to a state where Samsung can't detect that you've been running custom software on it.

Unless you have a TA backup in which case you can do whatever you want.
I'm too much of a ***** to confirm the following theory, but I wouldn't be completely surprised if someone who flashed the wrong TA-backup was able to start the phone in fastboot mode, unlock the bootloader again (perhaps with the unlock token matching the new TA), and flash his own TA from CyanogenMod or something. (Do not quote me on this please, not taking responsibility for someone breaking their phone trying this.)

Restoring a ta that did not come from your phone will result in a hard brick, nobody should try it EVER

Bootloader Unlock Tip

Hey All,
I've seen some posts stating that the bootloader for this phone can't be unlocked.
I'm using the E6533 model and wanted to confirm that it is possible.
Just go to this website: http://developer.sonymobile.com/unlockbootloader/ (the official sony one)
Select Xperia Z3 as the model (I know we have the Z4/Z3+ but it still works). Enter your email and click the link they email you.
Insert the IMEI number and they will give you the unlock code. then just run
adb reboot bootloader
fastboot oem unlock <code>
and it will work.
As a note this WILL wipe your device, so backup anything you may need on it.
Hopefully with this we can get root / twrp built

So TA backup is needed to keep the DRM keys before unlocking the bootloader. Is there a way to back up TA of non-rooted devices? Flashtool doesn't fully support Z3+ yet.

help
Quick question , what to do if you have Unlock allowed: No?

Generally speaking this always meant just what it says... That it's not possible to unlock the bootloader. This was often the case with oem phones. Today it could also mean you have myxperia security activated. If you have log out of that and try again.
Oh and do not activate it after unlocking bootloader, you could brick your device for good!

It prevents the bootloader from being unlocked. Otherwise it means your carrier disabled the feature

Thanks diemadedrei and ChrisJ951.
It worked, it was the Xperia Security software that was enabled.

Rooting status: unknown
Hello, i tried to unlock my BL from the sony website, but after i flashed the code in my phone, it just restored and now just says rooting status: unknown and also the option of unlock allowed does not even appear! anybody could please help me?
thanks and hello from Mexico!

The z3+ is now selectable on the unlock page officially
@bryantronics: it should say bootloader unlocked yes under rooting status. Generally it should have worked if everything went as described.

Thanks to all, I have tried to change it to "YES" 24 hours

OK so with this recent tidbit of data that a bootloader unlock no could become a yes I am concerned. When I bought the phone it said yes. But no where can I figure out if the DRM keys are a)original b)intact c) working with this present rom. Could anyone tell me so I can be sure that if I resell this item I don't misrepresent this information.

haist i have a same problem for that issue ...until now i can not flash boot img...please resolve this problem...guys plssssss......

i have the same problem i cant flash img due to remoted lock state: unlocked

any updates?
I am suffering the same problems as my colleagues in the previous posts. I cannot get the bootloader unlock, no matter how hard I try:
performed the official Sony way (using minimal adb and fastboot; phone is listed in fastboot devices; "remote: command not allowed")
flashtool64: both with blu manually and by leaving the text file in the registered devices folder (which was found and used for a unlock, which turned out not to be successful).
Sony MyDevices is not activated. Android 5.0.2 (E6533; 28 0 A 8 272 HK)
Do you have any further tips how to open the bootloader?
thx, Benedikt

Hey All,
I've seen some posts stating that the bootloader for this phone can't be unlocked.
I'm using the E6533 model and wanted to confirm that it is possible.
Just go to this website: http://developer.sonymobile.com/unlockbootloader/ (the official sony one)
Select Xperia Z3 as the model (I know we have the Z4/Z3+ but it still works). Enter your email and click the link they email you.
Insert the IMEI number and they will give you the unlock code. then just run
adb reboot bootloader
fastboot oem unlock <code>
and it will work.
As a note this WILL wipe your device, so backup anything you may need on it.
Hopefully with this we can get root / twrp built

hi
How long does it take to unlock ? the bootloader. I've waited for long.

Unlock bootloader NO
Any solution

i was crashing my head to do it and nothing to it done, and I discovered that the problem was that my xperia was enabled, so I disabled it and finally unlocked the bootloader

I had bootloader unlock allowed: no on latest firmware. I backed to Android 6 a I have bootloader unlock allowed: yes
