Xperia Acro......root? unlock? fastboot? anything?

Hey guys,
Just picked up the Japanese Xperia Acro with au/KDDI in Japan. From what I gathered, the phone is almost exactly the same as the Xperia Arc, only difference in name, so I felt it'd be best to post here.
Anyway, great phone, but I'm desperate to root it and then overclock the processor. Thing is, it's branded with the carrier, so I'm unable to access fastboot loader. (Holding menu and plugging in usb doesn't trigger blue light)
Considering this is my first Android phone, I'm literally stuck on where to go from here. Is it impossible for me to root this phone and load custom firmware due to it being locked with the carrier? Am I really stuck with an untinkerable phone?
Appreciate your help guys...

I can unlock your bootloader remotely and enable fastboot for you
The process uses testpoint which is in a different position from the Arc

Sounds good!
How can I arrange this?

Hi Jinx13. Would you be able to remotely unlock the bootloader on my Xperia Arc? I've tried searching through forums for the past couple of days to unlock the bootloader but can't manage it. I'm with Rogers Canada, I unlocked the sim and debranded the phone (I think).
Thanks.

I have same phone and now i have a galaxy note 3 too so i don't use acro anymore. so i wanted to root my acro phone. i know what you are going throw because acro phone is unable to root. So i flashed the firmware and then i could root my phone and everything is working fine. Originally my acro had "IS11S_4.0.1.B.0.118_au" firmware so i flashed it in to "IS11S_4.0.1.B.0.112_KDDI" then i could root acro. if you want to know all the steps let me know i'll post all the steps.
Good Luck.!

- I don't know you can use it in UK or not. But i think if you can find CDMA mobile network provider yo may have a chance to use it. Also you may need you sim unlock.
Install Flastools and Flashing a new firmware
OK this is how i flash my firmware.
I have a Windows 8.1 running PC so this is the steps i did.
First you need to download two files so first download below files.
IS11S_4.0.1.B.0.112_KDDI.ftf
https://mega.co.nz/#!kVInSCQQ!bx7sX1izriRgHK14dmXC1r2LEKTZ4By6CBW5UjAcqww
flashtool-0.9.18.3-windows.exe
https://mega.co.nz/#!JVpBjTaI!fV-1JgQm7-bmMbL-xBxYOKhDAMZcS-aUsIreEm_gvFk
Then you need to install flashtool-0.9.18.3-windows.exe. Just double click and install it and Remember the installing folder (Example - "C:\Flashtool" or "C:\Program Files\Flashtool" like that) and then go to that folder. Inside that folder go to drivers folder and install Flashtool-drivers.exe. Click next check the Flashmode Drivers and Fastboot Drivers (Very important you select those) and go down the menu and select the phone model (Read all well). Then install. If your installation finis without warning errors then you ok. If your installation finis with warning errors then do next step.
Go to PC Settings (Charms Bar) > Change PC Settings > Update And Recovery > Recovery > Restart Now (Advanced Startup)
it will restart to Advance Startup automatically
In Advance Startup -
Troubleshoot > Advanced Settings > Start-up Settings > Restart
After rebooted you will get a screen says. Here to choose options for that we have to use function keys. Now press "F7" to select "Disable Driver Signature Enforcement" .
Now your PC will boot with Disabled Driver Signature Enforcement and you will be able to install Flashtool/Fastboot drivers. so again install the Flashtool-drivers.exe and will finish without errors.
after that again go to falshtool installed folder and go to Firmwares folder and if you see any files already on that firmwares folder delete them. Then copy IS11S_4.0.1.B.0.112_KDDI.ftf file that you download before to firmwares folder. and then run FlashTool.exe (If your PC 64bit then run FlashTool64.exe)
Now on your device go to (Very important to do all the steps below)
01. settings > Application settings > Development > check USB debugging
02. settings > Application settings > uncheck Unknown sources
03. settings > Sony Ericsson > Connectivity > USB connection mode > choose Mass storage mode
Then connect your device to PC using Original USB cable.
Go to flashtool software click on flash icon.
Then chose Flashmode > ok
Then new window will open (Firmware Selector) then you can see the IS11S_4.0.1.B.0.112_KDDI.ftf file already on that.
Now just click on FLASH.!
That's all wait it to finish. and your device will restart automatically. and DONE.!
I couldn't remember where i download those files but i already had those so i upload it for you and anyone who want to download those.
And if this post helps you then be kind enough to click on THANKS for me.!
Enjoy.!

[Q] I'm F*cked. Can't get intro Fastboot

So... I've flashed my baseband using the baseband software provided by this thread : http://forum.xda-developers.com/showthread.php?t=1308849
And now I am stuck at the SonyEricsson loading...
I can't get intro fastboot "mode"
And it's safe to say that I am pretty much f*cked, the working help will get a surprise.
A steam key for Borderlands.
So here is what you need to know : I am from Sweden an my provider is Telenor.
The android version before I flashed the baseband was 2.3.3. Don't know the version of the baseband. My Windows won't allow the MTP driver to be installed, don't know why. And I'm booted with the requirement of driver-signatures disabled.
Please help me!

Xperia ion Bootloader Unlocking & Relocking

Taken from [Tutorial] Xperia S/P/U/Sola Bootloader Unlocking & Relocking and modified slightly for the ion. I take no credit for this tutorial.
Quick tutorial for unlocking & relocking the bootloader of the Xperia ion.
This is the official way to unlock bootloader
Warning!
This procedure will wipe the /data partition of your phone, so you will loose all ur stored data, settings. SDCARD will NOT BE WIPED!!!
DRM keys WILL be lost forever
Why should I unlock the bootloader?
You can flash custom ROMs/Kernels.
You don't need to worry if the new firmware can be rooted or not as with unlocked bootloader you can always ROOT your device.
SE/Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011 line (they had ICS alpha/beta), so who knows may be SE/Sony may give early builds of ICS (JellyBean???)
Most of this is taken from lollylost100's his tutorial from ARC thread (all credits for that concise tutorial go to him, i have elaborated on a few things and added device specific changes)
[ Before we begin unlocking bootloader ]
Get the IMEI code for your device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
Download the fastboot package with usb drivers (alternate drivers if the ones in package dont work)
Make sure u have a windows PC with USB cable to connect the phone
Power down your phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
Once drivers are installed just disconnect cable and power on device
[ how to unlock ] (official way)
Go to: http://unlockbootloader.sonymobile.com/ and read everything!
At the bottom click 'Start Unlocking the Bootloader'
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the phone dial pad and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Click to expand...
Click to collapse
After you have verified that you can unlock bootloader, scroll to the bottom of the page and click "Continue"
You will get "Are you sure prompt" accept it by clicking "yes i am sure" (i assume that you have read an understood it)
Then accept the "legal terms"
Finally you will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
You should now receive your unique unlock key, its displayed on screen, SAVE THIS KEY SAFELY
Extract fastboot_with_Android_USB_file.rar and open fastboot folder
Hold SHIFT and right click on the background of the folder
Select 'Open command window here'
Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected
Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which you received earlier.
Your device should now be bootloader unlocked
If this tutorial is too much for you then itskapil wrote a step-by-step guide (and recorded a video also):
-Instructions: http://www.theandroidsoul.com/how-to...-play-neo-pro/
-Video: http://www.youtube.com/watch?v=LRH3pC7MhEA
(the above videos and some steps are for Xperia 2011 devices, but most the steps are same for Xperia ion)
Info on Relocking bootloader is in next post

Relocking bootloader
RELOCKING BOOTLOADER WILL ALLOW YOU TO GET NEWEST UPDATES & REPAIR DEVICE USING SEUS/PCC
Before we begin relocking the bootloader make sure that u have flashtool download & installed
You can get the latest version of FlashTool from:
http://androxyde.github.com/Flashtool/
Download link is under "Installation" tab
If you have not use FlashTool before read this thread:
http://forum.xda-developers.com/showthread.php?t=1526866
Download this FTF:
Xperia ion -> LT28-ION_Relock_bootloader_Dogsly-TEST.ftf // Mirror 1
Flash this FTF via FlashTool:
When it says enter flashmode, power down device and keeping VOLUME DOWN button pressed connect usb cable to phone, the device will now enter flashmode (green LED)
After this file is flashed reboot phone
Bootloader will now be relocked!!!
Incase device doesn't boot DO NOT PANIC... You can flash stock firmware FTF anytime to get back to stock ROM
P.S.: there is no official way to relock bootloader

So because my phone says I can't unlock the bootloader, does that mean I can never unlock the bootloader? Or do I have to wait to be able to root it first?
PS: I got my ion from Best Buy so is that why? Will I ever be able to unlock the BL ? I've rooted and unlocked my x10, back in the old days lol but I'm just wondering if there's any difference with getting a phone from at&t directly or from the sony store and best buy.

Have to wait to see if another way to unlock the bootloader is discovered. Root and unlocking the bootloader are two different things that accomplish or allow different things you can do on the phone.
IE rooting allows you to uninstall system apps & bloatware, backup apps/data, make changes to build.prop etc. Unlocking the bootloader will give you access to fastboot so you can flash custom roms/kernels and other images such as a pre-rooted system image to gain root.

I wonder. If we can not unlock the bootloader for some LT28at, why is there a key to unlock it? I did the Sony bootloader unlock for fun and apparently they have a key for my LT28at even though it says bootloader unlock is not allowed.

I understand that works for lt28i but I'm referring to lt28at the us model of the ion and why there is a bootlloader unlock code when we can't unlock it.

see if it works

Has anyone with an ion that has
Bootloader unlock allowed says Yes

tried to unlock it via the sony site and if you did and it was successful have you tried to relock it using the file linked above? Would be nice to know if that works.

Possible fix?
If the LT28i can be unlocked, what if we flash the international firmware on our LT28at's and then do the LT28i method? Maybe a stupid question but this is the first phone I've had that's a challenge to do stuff like unlocking and rooting. My last phone (HTC Aria) was extremely easy.

Flashing firmwares does not change the ability to unlock the bootloader.

Kinda figured that

I tried to relock the bootloader. The flash pass but the phone can't turn on after that.
*I reflash the stock kernel again and the phone can power on now.
So here is the result, once you relock bootloader, you need to flash back the stock kernel in other to turn on the phone. Hopefully this will help those people who got stuck after relock bootloader.

Hello guys
I was just wondering, if bootloader unlock or flashing cutom kernel will allow to use sim cards from other mobile operators (European for ex.) ?
I have an ability to buy this device in us through my friend. but Im interested if I would be able to use it in Europe I was thinking of buying xperia p or s, but they dont have microsd card support.
Im not interested in using LTE networks. Just common 2g.
I planning to use it like a second android device as a multimedia player instead of my galaxy s wifi5.0. (because of good sound quality and other features).
Thanx a lot for responses

No. You can't unlock the bootloader of the lt28at and you can't sim unlock it either. Best bet is get an international version not one from the US.

You have to make sure that your phone has unlocked bootloader, if it says "bootloader unlock allowed: yes" it doesn't mean your phone is unlocked, it only tells you that it can be unlocked.
If you have TrackID, try to play it, if it can be played, then the bootloader is still locked.
For unlocking, try the link below. And don't forget to thank them.

1. rooted the device
2. installed CWM
3. wiped everything
4. installed UHD and choosing just one app to install
5. unticked reboot
6. wiped Dalvik Cache ONLY
7. reboot device from CWM
8. Enjoyed UHD

UHD is stock based so it will work on locked boot loader, if it doesnt then you're doing something wrongly.

Not necessarily! choosing to install all the apps in the AROMA Installer causes sticking on Sony logo in locked bootloaders.

Xperia M doesn't boot after unlocking bootloader

HELP NEEDED!
Hi guys,
So I tried to unlock bootloader on my Xperia M (C1904). And after unlocking, it doesn't boot anymore. Just shows "Sony", and "Xperia", then the wave animation forever.
First of all, I access to Sony Developer World for unlock bootloader key, then used flashtool's BLU feature. It successfully completed and said "Device will reboot into system now" However it showed the wave animation forever, (waited for around 20 or more minutes) but there was no change, so I flashed stock .ftf file via Flashmode. HOWEVER, everything was the same as before.
Then I used BLU feature again to try Re-locking the bootloader, but it said that "Processing of loader.sin finished with errors." and "Your phone bootloader cannot be officially unlocked". I am sure that my XM is bootloader unlocking supported, and flashtool successfully finished unlocking.
I searched around the Internet and found many people is having same problem with me.
I DID try using Sony PC Companion to repair the software, but as you can imagine. It simply showed ERROR.
I need your help as fast as possible.
Thank you, and sorry for my bad English btw.
PS I did read XDA threads about this problem, but nothing helped much.

HELP NEEDED!
Hi guys,
So I tried to unlock bootloader on my Xperia M (C1904). And after unlocking, it doesn't boot anymore. Just shows "Sony", and "Xperia", then the wave animation forever.
First of all, I access to Sony Developer World for unlock bootloader key, then used flashtool's BLU feature. It successfully completed and said "Device will reboot into system now" However it showed the wave animation forever, (waited for around 20 or more minutes) but there was no change, so I flashed stock .ftf file via Flashmode. HOWEVER, everything was the same as before.
Then I used BLU feature again to try Re-locking the bootloader, but it said that "Processing of loader.sin finished with errors." and "Your phone bootloader cannot be officially unlocked". I am sure that my XM is bootloader unlocking supported, and flashtool successfully finished unlocking.

Buddy download stock firmware that works with your device(c1904) and I have heard that newley flashtool have some bugs most of the peoples found it difficult to use due to error so download a old version of flashtool.
Here is the link for flashtool that I use
https://drive.google.com/file/d/0B3WS5xjTt_0tQTZzQmNiZFc0R2M/view?pref=2&pli=1
It works smooth and don't forget to install drivers for xperia M found in C:/Flashtool/drivers after unpacking flashtool

Thank you guys for helping me.
I tried re-locking and flashed the stock firmware, and now my XM is working normally again.
Now, the question is, "Is there a way to safely unlock bootloader without soft bricking?"

I did follow those steps yesterday, and flashtool said it DID unlock the bootloader, but my phone didn't boot at all and all those things happened. Should I try the same steps again and see if it works this time?

flashtool bug
I had similar problems as described in the first thread.
My flashtool version was 0.9.19.8 and during the blu-process the level meter stucks.
With "new" version 09.18.1 - as mentioned in one of the early replys - everything worked well.

Buddy for first time soft bricking happens with all it happened with me too because for first time the DRM keys (a kind of key used to get sony official support and update OTA) get wiped forever since DRM keys are integral part of BOOT so it will led to softbrick only for first time after that you can easily unlock or relock your Device

Well, you should be able to check if your device is unlocked when you connect to flashtool, can't you?
