Why does Xperia 2011 need unlocked bootloader? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Sorry, i'm still on xperia x10 mini pro, just asking why is that? I mean, with x10 family, the only thing it needs is to use superOneClick and flash the rom from clockwork or xrecovery. With 2011 lineup, it's like that we need to unlock bootloader first using fastboot etc.. Why is that? Can anybody share with me?

There is new rooting method for 2011 xperia without unlocking bootloader.
So now we have choices, unlock bootloader or not, depends on your need.
Regarding your question why we need to unlock bootloader before rooting is because they haven't found a security hole at that moment.
Now don't bother to unlock bootloader if what you want is just rooting the phone, unless you want to flash a custom kernel

Hey, I'm new in this section and I want to unlock bootloader for flash custom Kernel but my phone (SK17i) doesn't want boot in fastmod.
I cant unlock because nothing happens when I hold up & plug usb. Led just gone gren and logo battery charge appairs. As result, comand "fastboot.exe -i 0x0fce getvar version" stay on <Waiting for device>.
However when I hold DOWN & plug usb, driver "SEMC Fash Device" appairs on device manage for 30 seconds and battery logo appairs.
I've already debranded my "Orange" phone with "X10FlashTool" for a généric 4.0.2.A.58 and rooted it.
Maybe it's a driver problem ? But y tried on 2 pc several time..
Somone can tell me exactly what is the name of the driver on device manager ?
I have "SEMC Fash Device" when I plug my phone and "Sony Ericsson seehcri Control Device" always here.
Sorry for my bad english, if somone can help !
Devilo.

You dont have fastboot on your phone atm. You need to pay someone to enable fastboot.
Search forum next time.

Guide [for beginners] - How To Unlock Bootloader via Flashtool

I am assuming your phone can be bootloader unlocked and you have unlocking key from sony.
If you don't know then refer to this post http://forum.xda-developers.com/showthread.php?t=1527159
WARNING: IT WILL WIPE YOUR PHONE DATA SO MAKE BACKUP
1. Install Flashboot and Fastboot drivers of Flashtool (setup file will be on C:\Flashtool\drivers or similar place).
2. Turn on your phone, and connect with usb debugging on.
3. Go to Plugins-> Bootloader Unlock option, start it.
4. Now it will ask to disconnect your phone and reboot in FLASHMODE.
5. Again reboot your phone in FASTBOOT mode.
6. It will show a window with your IMEI number, insert your unlock key and click "unlock".
7. The device will reboot and you are done!
FLASHMODE
You can get into flashmode by pressing specific hardware key and connecting phone to pc via USB.
It will glow GREEN LIGHT on led if done correctly.
Hardware key-
Back Button (X8, X10, X10 mini, X10 mini pro, Play, Arc, Arc S, Neo, Neo V, Pro)
Volume Down Button (Xperia U,P,S,Sola)
FASTBOOT Mode
You get into fastboot mode by turning off your phone, then pressing the fastboot mode key button, and connecting the USB to your phone. Done correctly and you should see a BLUE LIGHT on the power button.
Hardware key-
Menu Botton (Xperia Arc, Arc S, Neo, Neo V, Pro)
Volume Up Botton (Xperia U,P,S,Sola)

yes, turn off your phone then connect USB while pressing specific key.
same applies for fastboot method
When I am installing drivers, I am getting "don't install or install anyway", I choose install anyway but the same window comes up again. Should my phone be turned on, off or in flashmode or something?

I got an error in last step : Failed (remote: oem unlock failed ). This happened to me too when i used the official way to unlock my sony xperia p. Can someone help?

did u check that your device can be unlocked or not?
Yes I checked, it can be unlocked
If you have installed Flashtools and its drivers correct you shouldn't get any driver prompts when plugging the phone in
Assuming you did a default install browse to C:\Flashtool\drivers and execute the drivers file. Make sure you select the drivers for you phone ie "Xperia U" and scroll to the bottom of the list and select Flashboot and Fastboot drivers. From what I have seen so far most people are not installing these 3 drivers.
karimkahale: I would go back to the Sony website and get your unlock code again. Maybe you entered some wrong details...
Please help me out,
when I am trying to install fastboot drivers from flashtools drivers folder, I am getting an error saying driver installation failed.
My os is windows 8 pro 64bit..My phone Xperia U (ICS)
What should I do.

Successfully installed Fastboot driver on windows 8 (Used Advance Startup for installing unsigned drivers)through Flashtools and also unlocked bootloader..
Accidently lost all data as unlocking bootloader wipes data...forgot to take a backup but m happy.
Thank you for this tutorial mate!
It's better if we can get unlock key from flashtool
Sent from my MT27i using xda premium
Thanks a million, but would my warranty be void immediately after I unlock the bootloader, what's the regulation about this matter, I'd like to keep my warranty.
---------- Post added at 10:00 AM ---------- Previous post was at 09:45 AM ----------
If i relocked the boot loader the warranty wouldn't be void, right?
Not quite;
It all depends on your repairman...
The standard, though, is, that the warranty is valid if the guys at the repair center can flash a stock ROM (.ftf) onto the phone. Some phones can do this without their bootloader being locked, but some can't do this after their bootloaders are unlocked, even if they are locked back afterwards...
Now, I have a question:
I'm having the same error as karimkahale...
Whatever I do, I get that stupid error, and not even Sony can help me (their support team (that needs a week to reply to a simple e-mail) said that thy don't know how to help)...!
Thanks a lot for the guide, it was really helpful!
Cheers!

You have to, actually....
To relock, you need to flash a ftf file via FlashTool...

[Q] Dead after unlock.

Hi
I unlocked my daughter's Ray with wotanserver and it worked fine but I think she might have done an OTA update as she got a message to say the the sim was unrecognised and she needed a reset, which she did and then brought the dead phone to me.
It does not boot at all and does not show up on the PC
BUT
It does get to the Sony logo when I plug in the charger or try to fastboot to PC. (Goes into fastboot with Flashtool but led goes red and is not recognise when I try to use ADB command line to use bootloader unlock with fastboot.)
Flashtool, S1tool and SUS all recognise it.
I have reflashed it with both Flashtool and SUS and tried repair with sitool and wotan.
I have tried different methods on the forum but nothing works even though it doesn't seem completely bricked.
Does anyone have any ideas?
Thanks

Thanks - it was worth a try!
Still no change except the loader has changed from r4A069 to R4A069.
Does this mean the bootloader is now definitely locked and I need to unlock it to get the phone to boot?

Yup ur BL now is locked

I though I should say that the power button does nothing at all, the phone only boots to Sony logo when connected to PC or the charger is plugged in.
Is it possible the boot loader is corrupted?
Since trying the OTA unbrick, apart from the bootloader being locked, I cannot connect in fastboot.
Having read around it could be that the Trim Area is corrupted but the fixes I have found do not work. When I try to flash a loader (x10 but meant to work on all xperias) I get an error from flashtool saying there is an error reading the loader,sin header..
Any ideas at all would really help.
Could anyone help if I try one step at a time?
First, I want to unlock the bootloader to see if that helps with the bootloop problem.
I cannot enter fastboot anymore to use flashtool or command prompt unlock.
When I connect to flashtool in fastboot, I get the message that the phone is connected without USB debugging and then the LED changes to red (charging) and the device disconnects.
Any ideas please?

[Q] Half way there! Problem flashing/unlocking/rooting SE st15i

Hey!
Now my device is installed as Xperia Mini, when device is on, is this the right driver?
When not installed (before I press Install PC Companion software on this computer)
it shows up as Sony Ericsson sa0102 ADB Interface Driver, and I have the option to choose between similar named drivers, non of which works. This doesnt seem right?
What driver should the device use before PC-Companion installs the Xperia Mini driver?
In flashmode, the device is installed as Android ADB device. This seems right if you follow other tutorials/guides!
But I still cant flash/root nor unlock bootloader.
I know I need to downgrade the stock software version .62 to either .42 or .58 (The latter I couldnt find, so I will try .42 fw)
Bootloader unlock allowed: yes
USB debugging: ON
Unknown sources: ON
USB connection mode: MSC
Driver signature enforcement: OFF
Flashtool -> Throws error both on BLU and Flash, says my bootloader cant be officially unlocked
Doomlords v.4 -> Cant chmod/copy/install, but it seems it can push zergRush, if that means it "transferring" the app to the device
SE Bootloader_Unlocking_Relocking -> Throws exception when trying to flash, and hangs when I try to unlock the bootloader
SuperOneClick -> Shows half the process of zergRush then hangs, doesnt matter the method (zergRush, psnauter, GingerBreak)
fastboot.exe -i 0x0fce getvar version-> stuck at < waiting for device >
But "adb devices" shows the device! Is there a way to flash, root or unlock the bootloader with ADB?
This part might be the source of the whole mess!
Another problem im facing, probably highly crusial, when I try to upgrade the stock firmware neither PC-Companion nor SE update service can finish the upgrade!! It doesnt recognise my device when I being prompted to connect my phone in flashmode. I'm stuck here...
This might be a problem someone has encontered, and might share som insight in!?
When solved, I'll edit this thread to be "for those who facing the same issues as I'm doing!" And explain the exact details how and which drivers to install, and when!
And if I dont solve it, I'll think I'm gonna give Sony Ericsson a call after I posted on there official forums!

hmm that sounds crazy. idk how this could be.....
but what you can do is:
1. download sony pc companion software & reset, repair or update the phone if avaiable.
=> if still bootloader unlock allowed: NO then:
2. download & install flashtool. after iit install install its drivers from flashtool/drivers folder (need your phone driver + fastboot + flash driver) optional: install android SDK. (just leave all it is & press install packages.) if you done, flash a stockICS.ftf (<= firmware) like shown on this page: http://talk.sonymobile.com/t5/Android-development/GUIDE-How-to-Install-Jelly-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389 (you can download the firmware there, just make sure you choose your model right. use ICS .587) (boot once)
now look if bootloader unlock allowed....
if still : NO, then maybe ask your carrier where u get this phone. normally if your contract is end, they unlock your device for free (its here like that.)
you can also try just to request a code from sony site & try to unlock it maybe you are lucky. (you said you was allowed on pre version)
good luck!!!
the thing is if your bootloader locked = no cutom kernels = NO JB or KK rom for you. only stock based custom roms for locked bl...

[Q] WT19i no reaction, no lights after flashing

Hello everyone,
please help me out.
I tried to flash a custom rom on my sony ericsson live with walkman but flashed a wrong file using fastboot. It was just a mistake and it was done after one second since the file size was only 90kb. There was no chance I could have stopped it. And now I have no access to flash mode, or fastboot. Battery is not chanrging anymore. It seems it is bricked :crying:
Is there any tool which can flash the hardware again? May be kinda developer tool... It makes me sad
Please help!!!

i have a similar problem. i have a wt19i manufactured 11w48 with .62 fw. i can't enter flashmode or fastboot. the led blink for like 0,5 seconds and then it boot into charging mode,showing the batttery on the display.i've tried testpoint, flashtool, s1tool(that says "finished", but can't flash anything since i can't enter flashmode nor fastboot) and every other method here, tried to restore/update with pc companion, but it's impossible without entering flashmode. how do i know if i have unlocked bootloader since s1tool seems to unlock but flashmode and fastboot aren't working? i have already rooted and bootloader status "yes". i have successfully unlocked/rooted/flashed in the past x10 mini(x2),xperia mini,xperia neo, xperia ray, xperia play,an lg p350, a galaxy ace..anybody willing to help? can't seem to find anything here on xda, everything i've tried doesn't work no flashmode or fastboot, just 0,5 seconds blinking led.anyone knows if is there a way or how to uninstall drivers so i can do a clean install? i've tried both the android sdk adb, s1 tool drivers and flashtools flashmode/ fastboot drivers..and last, couldit possibly be a hardware isue? phoneis working great and has no problem aside of what's said above..
