[Tool][Unlocker][April - 01]3rd Party Bootloader Unlock tool

Hi all,
I have managed to create a third party tool that will unlock the bootloader of the Xperia T (It should work on Xperia TX/TL/V users as well) where the service menu says "bootloader unlock allowed:= No"
Downloading this will NOT break Bravia or track ID or anything else
If you have previously unlocked via the official way then downloading this will work for you too
It works by utilising a new release of a .zip archive and incorporating .img (Images) files that will guide you through the process.
All you need to do is:-
Download the attachment.
Save it on your desktop
Extract the contents to your desktop and read the instructions.
It should work on PC's and Macs
Please report back what you think.

Thanks,
Which device was it?
Also you could try this when connecting the phone in flashmode
Code:
Press volume up twice, release, press power button briefly, then both together for 5 seconds, hold and put in the usb cable

Doing this button combination doesn't do anything.

This is a special flashmode
"Qualcomm download flashmode"
and its used by Sony engineers to "force" a locked bootloader to flashmode when it doesnt want to. Its not normally needed but for some non Xperia devices it is

Does that work in xperia tx????

[Solved] Help!! Xperia Z bricked after trying to unlock bootloader

[solved] Sorry for my English first, I have been reading thousand thread but with no luck.
My xperia Z is
- locked bootloader
- no root
- didn't install driver properly (I guess)
I was trying to unlock bootloader, but the driver wasn't installed properly somehow as using flashtool even I followed step by step to install. Then, it got stuck for an hour at "Device connected in flash mode". I had to reset the device (power with - volume) with no choice. Now I keep rebooting at the colorful wave after Song logo.
I know flashtool is the only choice for me now, but i can't go in fastboot mode(- volume then plug in usb) because of the bad ADB driver probably. LED is no light (no blue, red, green) at all.
Also, ADB driver that i need to install now, but boot loop on my device is so swift that ADB driver doesn't have enough time to install to my device.
I am stuck at this stage for a few days. Any idea what I should do now???
PS: using latest flashtool

Since you have a locked BL, Flashtool isn't your only solution...
Install the correct drivers if you haven't already, after that use Sony's updating service to restore your phone.

I just tried sony's updaing service in which fastboot mode was needed.
Since i install the bad ADB driver, how can i install the driver at this stage? should I install from flashtool?
I did uninstalled the driver and install back again from flashtool. Fastboot mode doesn't seem to response at all means. I actually followed the step by step guide from flashtool thread, but i don't think i install the driver properly somehow.

Flash mode is volume down + connect the usb.

sorry i wrote it wrong, i did volume - then plug usb

Volume up + power for 15 seconds to shutdown your phone(3 vibrations).
Repair with Sony update service and don't forget volume down.
Or try another pc.

thanks for your reply again. Since i don't have another pc, any other means that I can get to the fastboot mode? (I can't install driver to my device properly because of bootloop perhaps)

Uhm, the drivers are installed on your PC, it should work on your phone no matter what.
Of course, you need to have installed the correct drivers and in the correct way. Try to reinstall the drivers (Sony Updating service will give you a link if I'm correct, use that one).
After that use another usb port and try it again.

Thanks for your reply.
prove me wrong if i say thing wrong. the ADB driver are installed on PC only and will not install on device? if so, no matter what my device status is, it should be able to connect to fastboot mode as long as it has enough battery?
Also, i just checked Sony Updating service that doesn't provide the driver and function like fasttool. Could you kindly send me the link of this driver so as to not screwing this up again?

You don't need fastboot drivers to use sony update service.
Anyway sus should install the drivers for you when you connect the phone by holding volume down.
You should download sus software not using the web update.
When you connect the phone go to device manager on your pc and check if all the drivers are ok and no yellow signs.

[Q] Xperia SP cannot update firmware

Hi Guys,
I have recently bought a Xperia SP C5302 and am running the 12.0.a.1.211 firmware.
My problem is that recently Sony PC Companion informed me that there is a new
firmware version out 12.0.a.1.284 and suggested I update. My PC proceeded to download the update
and it asked me to switch off the phone and while pressing the volume down button,
plug in the USB cable. I did exactly that and no response. I tried everything again and still nothing.
I have gone to the official Sony site and checked and they claim that its the Volume Up button,
here is the link..........
unlockbootloader.sonymobile.com/fastboot-buttons ( I am not allowed links)
I may have gotten confused with the Fastboot and the Flash tool but however I have flashed a xperia phone before.
I flashed my old Neo V from gingerbread to ICS with no problems.
So my question is this: How do I install this update if my phone wont go to the Flash tool utility or whatever its called?
The volume up and down buttons do not work and I have tried to install Sony's other programs such as Update Service and
Update Engine.........all to no avail.
Some suggestions regarding this matter would be greatly appreciated.
Thanks!

Can't really help with prob but can help to clarify the button pushing.
Button up=fast boot
Button down= flash mode
You can always use flash tools which you can Google for.
Then download any of the .257 or .284 builds put the file inside flash tools folder and then install this to phone while connected to PC in flash mode.
Sent from my C5303 using xda premium

Thanks but what is the difference between the Fastboot and the Flash Mode?
Your suggestion is good except I cant enter either mode at all. I push the buttons and nothing happens.
I use the same program and the same PC but my girlfriends Xperia L handset and it jumps to both modes
fine. When I push the down button on her phone I see immediately on my PC that it has found new hardware
(SEMC Flash device) and when I push the volume up button I see the Blue LED notification light, which from my
research indicated that it has entered Fastboot mode.

Check to see that you have installed the drivers correctly for your phone, if you have the old flashtool then download and upgrade to the latest one and install all the drivers included with it, might work after that.

The difference between them is one is used for flashing stock roms to your phone this flash mode y pressing button down and keeping down while connecting cable to PC.
Fastboot mode is only available if your bootloader is unlocked this is used for sending kernels to your phone again this fine while holding the button up keeping pressed up while connecting Cale to PC.
As suggested forget using PCC or sus but use flash tools instead.

I have never played around with the Bootloader before nor with Custom Roms so I am unsure
to which flash tool you are referring to. is it the one found at the Sony Developers Website?
The one that has the Emma file or whatever embedded?
Also my PC which is running Win 7 Pro installs the drivers automatically for me and as long
as they are successfully installed I am also unsure as to how to make sure that they are the
right ones.
Assuming that I do use Flash tools, where do I get the patch build file or whatever to update the software?
Will this void the warranty?
Many Thanks!

Flashtools is a third party tool that was created by xda devs. It is really easy to use and set up.
It works in same way as Sony update service or PC companion but you are not restricted by what software you can install.
Follow this link to download on PC http://androxyde.github.io/
Install on PC, connect phone to PC while switched on It may prompt you to install drivers.
On this forum most Sony users use this rather than Sony's software.
You can find links to the .257 and .284 builds these are in a file format that flashtools use so no need to extract or rename.
Once installed open flashtools folder and you will see other folders this is where you put any of the roms stock, custom , kernels etc
The only way you will lose warranty is by opening bootloader using flashtools to install software will not lose warranty.
When you are ready to use flashtools power down device and hold volume button down for flash or vol up for fast boot then connect came to PC....
As regards drivers on PC not working I am sure what to say it why you can't buy flashtools does come with drivers for Sp so would say download, install then try connecting phone.
If this don't work I can't help anymore sorry.

Hold The power and volume button up or down Together Don't plug it to the. Then check if bottom led lights blink or not. It should Blink with a specific color depending on which button u hold volume up or down and let me know asap.

You are wrong about that. It asks you at some point to unplug your phone switch it off and enter flash mode.
Anyways sent my phone back to Sony and they replaced the board. They don't seem to know what's wrong either. They couldn't get it to enter flash mode either.

I know this is a late reply but as I said before in a previous post, I sent the phone to a Sony Repair Center and they ended
up replacing the motherboard for me as something was wrong with it. If nothing you do seems to work then it might just
be a hardware problem and needs to be checked out.
I have sold my SP and bought a Galaxy S3 and had the same issue trying to install custom ROM. Couldnt flash anything at all and
problem was hardware related as well. eMMC chip was faulty and had to replace the eMMC chip and the motherboard.
Good Luck with yours! Hope it was fixed!

Need Help.

My sony xperia z will not power on anymore. If i connect it to a charger, it shows the sony logo and keeps restarting. When i connect it to my computer not much happens. SUS can detect it and i tried updating it, it downloads and installs and tells me to restart my phone but still nothing happens and the same thing as before happens when i connect it with a charger.Sony PC Companion app does not detect the phone.
So i tried flashing with xperia flasher and i downloaded a 4.3 stock rom, flashed it but then at the end it says usb debugging mode must be enabled but i do not think its enabled, nor can i check since my phone does not power on.
Please Help!!!

Though I hold vol.+ and power ,device vibrated ,but nothing happen.

Dont press power button for fastboot mode just do power of if its vibrate 3 times than your phone is off OK? Next step is connect ur USB cable to PC than press only the vol up button !!!!!! not the power button!!!!!! and then connect ur phone with the USB cable so then just make fastboot flash bootimage Form a Rom of your choice vor stock firmware

Have you tried the hard reset button?
Under the flap next to where the sim goes, is a tiny hole. You need a pin to press and reset.
Edit: Do you have ADB installed? Have you installed the Sony drivers. on your PC?
You also need to run the exe in the Drivers folder within Flashtool, to make sure you have correct flashomde drivers available. Installing these drivers is very difficult in Windows 10 and it require restarting the machine in safe mode, and going into the advanced settings to disable driver signature checking, this how to video is for windows 8, but you'll get the idea
All of those need to be in place before flashtool will work.
Does it go into flashmode? Make sure it's turned off, start flashtool on your pc, then hold the volume down while plugging in the usb cable. If flashtool recognises it then you can follow bilboa1's great guide. You will probably have to start from scratch, old firmware, root exploit, recovery etc etc.

I installed all the drivers correctly , hard reset yellow does nothing. Now I use window7 to save my phone , I have found sth. useful. The device cpu send sth. about QHSUSB_BULK driver . Which means the the most basic software had lost. Now I am searching for the device bootloader .

Thread here lists installing QHSUSB driver, worth a go perhaps?
There is a thread dedicated to rescuing hardbrick devices

Exactly the same happened to me this morning. I had not time so I left it and came back at midday. After trying to reset it many times it finally turned on (maybe 15 min trying), but the USB port completely died... Then I notices son humidity in the two cameras crystals. The phone was working great, I even play asphalt 8 for 20 min and nothing wrong happened. I've just sent it to repair. Tech guy told my that maybe the motherboard is compromised.
The only thing I can surely tell you is keep trying, it worked for me.
