[OFFICAL] Work out how to enable fastboot for locked devices / Problem solved :D

So as you may already be aware phones like mine, (orange uk) have the fastboot locked down, and so we cant unlock the bootloader.
I for one believe it can be accessed but needs a little bit of time and research on getting it done.
This thread is aimed for brain-storming for ideas and collecting them for us to try out,
You can de-brand your phone by flashing the software from this thread

thanks to scott4 for the first upload mirror on page 3
Any ideas on getting the bootloader up and going on locked devices please put them in here

xperiax10.awesome said:
cool, finally I rooted my xperia ARC
these are very simple steps(copied from different threads):
1. Install the attached apk: Gingerbreak-v1.00
after installing most people getting this error - "could not extract assets".
TO OVERCOME THIS, just copy the attached ADB.zip and extract it on your laptop (windows)
say at
E:\mobile_Xperia\ADB
goto above path in your cmd promt and types these lines (your phone should be connected to laptop in debugging mode)
E:\mobile_Xperia\ADB>adb shell rmdir /data/local/tmp
E:\mobile_Xperia\ADB>adb shell mkdir /data/local/tmp
NOW JUST INSTALL THE apk file again and click on ROOT

if that Fails try replacing it with rm -r /data/local/tmp

Instructions
TESTPOINT INSTRUCTIONS PROVIDED BY mooxie FROM XDA FORUM:
1 turn of the phone
2 take of the backcover
3 remove the battery and sim card
4 take of the plastic covering the test point it's a bit stuck there but the gentle if you can.
5 Find something flexible like a wire or so i used steel wire. Make bend it so you easily can put it on the test point and the ground since you need to hold it there and press the powerbutton in the next step.
6 put in the battery
7 put the wire on the test point and the ground keep it there and press the power button for a few seconds. You wont get any confirmation that it suceeded.
8 Plug in the usb cable in the phone. Windows will now search for a new driver.
If it doesn't install automaticly. Go into the device manager of windows and look up something called SEMC_HUBB think it was that name. Choose update driver and browse to your omnius\driver folder. You will get a warning that the driver isn't signed but press okay and it should install.
9 Now if everything is done right the flashing will start and you should soon have an unlocked phone
Also side note i had problems with
qhsusb_dload driver not installing correctly.
if this is your case right click update and point to the omnius folder and choose update. worked for me.

Have you tried connecting via ADB, and running the command "adb reboot fastboot"?

No not sure how to do it for free, i think someone with a Japaneses version has removed it, i will PM him to ask him

Here's a thought: backup TA. Write random values to security area. If fastboot is disabled/enabled depending on TA simlock info, tampered sec. zone could give you fastboot. Then unlock bootloader and in order to get your phone back to life, restore TA.
Method should be 100% safe as long as you can write TA back.

Tampered units wont let the phone boot.

But what about flash mode and fastboot? I know they won't boot but that's why in the end TA is restored.

so now all you crazy kids with unlocked phones have root I dont suppose anyone has any more ideas about this problem do they?

I have a few more ieas;
1) I presume you have also tried
adb reboot bootloader
I haven't got my arc yet, Im just saying old ways of getting DHD into bootloader/fastboot
2)
Also, what i think was being mentioned above, Im not too sure what was being said, but on advent vega's and optimus 2x's if you wiped the boot partition, it rebooted into fastboot, because there was no OS installed.
3)
Another one to try is look for market apps that offer reboot into recovery type options and see if they work

have you tried booting your device using the S1 BOOTLOADER method and the S1 DOWNLOAD method? (power off, hold menu + plug battery, then plug cable in pc) you should see a blue LED light. (power off, hold back key + plug battery, then plug cable in pc) you should see a green LED light.
try these two methods and give us a feedback

manage to get Green light to come up, and it installs drivers
SEMC Flash Devices installs as the drivers,
After the installation of the new drivers still no blue light
adb reboot bootloader just reboots as normal

Hi !
For me, first method makes my phone booting normaly (no led light).
With the second one, it's OK : green led light appears.
If i can help...
PS : my PC doesn't want to install drivers :-(

so that means SEMC Flash is available. Try using Flashtool and flash a UK/Global firmware, and see if it works =)

Download SEUS. PC Companion doesn't install the right drivers.

Already flashed global firmware,
Still locked,

I guess the lock is actually in the bootloader level, which can't be overridden by writing a ftf package.
Sorry, but no other ideas at the moment =\

[Q] Waiting for the device

Hi there!
Well, yesterday i tried to unlock the bootloader of my phone (running gdx v014). I followed the steps correctly and when it comes to the cmd i pressed a key and it said:
Getting Root Rights
*Daemon not running. Starting it now*
*Daemon started succesfully*
I waited for 15min and nothing happened. I close the cmd and open it again, and the next time it said:
Getting Root Rights
And it stopped there.
So i flashed a stock rom with the flashtool and then the baseband 015, this without problems.
And when i tried again, the same happened. So i wanted to check if the phone was still rooted, so i opened the superoneclick, checked for the updates, follow the steps and something smilar happened.
It said the same as the cmd for unlocking the device (the daemon part), and then it said:
Waiting for the device
And superoneclick crashed.
Hopefully my phone is still working, but i would like to know if there is a way to solve this.
Thanks!
Goodbye!

do u have all drivers installed? maybe something standing in device manager with yellow exclamation mark?

do you have pc companion installed ? if not, install it. and also check if you have usb debugging aloved in phone menu

For me the first time it stucked at the "Waiting for device", so i rebot my phone, close the CMD and the ADB.exe that it opened and then tried again and it was sucessfull
But check if the drivers are intalled and the PC Companion recognizes your phone

Ill try installing PC Companion, to see if my phone is recognized.
Goodbye!
EDIT: Installed PC Companion, Superoneclick didnt crashed and rooted my phone... Now ill try to unlock the bootloader.

I will describe what programs showing because i have polish version and maybe you can't understand them:
When i'm trying to connect to pc companion when pc recognise phone i'm geting message PC companion could not connect with device disconnect device and try again
When trying do sof/hard reset nothing happens
When trying to pull in fastboot or flash mode pc recognise phone always the same in conrtol panel ZEUS FLASH device pc also recognise in thisa mode without battery and without pushing any buttons but i'm not geting any led Green or blue only when i'm conecting charger or usb cable WITHOUT battery it blinks red ones
When i'm trying to flash with flashtool or original update service when program is on screen asking me to connect the device i plug usb pc recognising the phone (usb connected device sound) but program doesn't start to flash or even recognise
i have also setool when i'm trying to flash by setool when program is waiting for device connecting bar is moving on down side of window when i connect the phone it is stoping like it tries to connect but nothing happens....
i was thinking to try this but i have cheked battery voltage and it is 3,88 so i thing it is fully charged:
Here are the steps I took successfully revise my phone from soft brick.
Let the phone charge (long long time = 4+ hrs) on wall charger.
Red light on (constantly - not flashing) - charge until red light off (again very long time =16+ hrs)
Unplug from wall
Run flashtool from PC and run flash .111 until it asks to put phone in flashmode
While hold volumn down and plug in USB
Red light will be back on, after a few seconds - flash will run.
Unplug USB then power on - phone will boot and die (it's okay don't worry)
Charge the phone again - after a while (or let it charge full), you can now turn on the phone.
That is all ... Back and running.
GOOD Luck.
Timing = could be different from phone to phone - depends on battery of the phone before it dead.
please do you have any idea? for me it hangs in some kind of boot mode and i don't know how to kick it fromthis and reflash if any screens can help please tell me i will do them

OK,
Yes thats true but it sounds similar to a problem I have come across before. But this happened when someone flashed the S1 update on the TX instead of the T.
Have you unistalled evrything android/sdk/adb related from your computer and started again.
Also, you can try another machine.
Are you on win8? That has issues with drivers from Sony.

I dont know where testpoint is on xperia T as we have never been down that road here.
Has he tried to use EMMA to flash something? That is meant only for unlocked bootloaders, maybe he has messed up with that, but I am onl guessing here and i cant really see why that would do anything to the boot...
Maybe he tried to flash it, dropped it, broke it, and thinks a software hack can help him....

Dead phone?

I just got my phone, i test it to see if it works and everything goes well
So now i start the process to unlock bootloader, then i get the token, the .bin and then flash it and it unlocks and restarts
Now i go and shut down the device and now it doesnt want to turn on, the screen is dead and when i connect the cable no light appears, although the device is somehow recognized by my PC when i connect it (Device Manager says My HTC)
I have tried holding power and volume down for 1 minute and nothing happens
Is there somehow to save the phone?

Did you try to longpress power when the phone is connected at pc?

Yes i have tried... In fact, the PC tries to recognize the phone in the Device Manager when i do this, but it fails and after a while it rolls back to Android 1.0 it says (I uninstalled HTC drivers)
Is there like a way to flash something to it while in this way?

When i run
fastboot devices
It says

No prob?

Yeah it showed battery like at 3% i guess it was too low
The thing is that it wouldnt show anything charging and no LED, but now it seems it is
Im gonna charge full and try to flash it again
Thanks !!

Probably your phone was in fastboot so you don't have the led.
However, good!
p.s. For thanking there is the button!

i wouldnt charge all the way. maybe 40% and try just in case you get stuck and button combo doesnt work(i havent had it happen but people have been reporting it). you will have to wait for the battery to die to recover and if its 100% that could take a while. also people have reported the led not coming on when battery is fully dead after plugging it in

Yeah i guess so but somehow it didnt show anything and volume down + power didnt work

HELP: Sony Xperia Z3 Compact Unknown USB Device (Device Descriptor Request Failed)

HI, I need help fixing my Z3 Compact (D5803).
-My phone had Android 4.4.4, had Root and had firmware 23.4.A.1.200 I believe. (some pre-rooted firmware)
-I flashed that firmware onto my phone a long time ago and its been running great ever since.
-Today I decided to try more flashing, I rushed it and accidentally flashed firmware for the Z3, not Z3 Compact, plus I forgot to turn on USB Debugging!!!!
-It pretty much failed flashing, tried to turn on my phone and I get the update failed screen.
-I researched it, looked into repairing it through PC Companion, but decided to try flashing again and still not seeing that I had the wrong firmware.
-It seemed to have flashed some of the way but had errors and stopped flashing, I tried turning on my phone but now I get nothing.
-No LED, no vibration, no Charge LED, no Update failed screen, no Sony logo, no nothing.
-The only thing I get is when I plug USB into my PC then into phone, it takes 10 seconds, then I get sound on PC and a notification saying (Unknown USB Device (Device Descriptor Request Failed) but still no LED light on my phone or vibration.
-I tried uninstalling the driver, I tried different button reset ideas, even tried the little yellow button next to the SIM card.
-I tried repairing it with PC Companion but it cant do that because it wont recognize it or respond to the (hold vol down then plug in USB).
-Didnt bother try fixing it with flash tool because I knew I'd have the same results as I did with PC Companion ^^^^^^^^
-I read some people say that the USB error can be a Hardware issue but I dont think it is because my phone worked fine before all this. (Unless the USB cable fried my phone some how???? lol
-I did make a backup before I did the flashing which I put on my micro SD card, and I had that out when I tried flashing so it should be safe
I think thats it. If theres any thing else that comes to mind that might help I'll add it in when I can.
Any help would be appreciated thanks!

Force install drivers using the "Have disk" option through the device manager control panel.
If the firmware that controls the USB interface and bootloader are corrupted, it's possible that it's hard bricked and needs to be recovered using JTAG.
I've had bricked phones due to hardware failures that caused the same error.

I've had bricked phones due to hardware failures that caused the same error.

Thanks for the reply.
My phone wont show up on the pc anymore. wont show unknown device in device manager neither.
When I first plug it in the LED shows red for a little then goes away, so I think the battery is dead, i charged it but still nothing shows up on the pc.
I would like to try and recover it using JTAG. I know how to open up the phone and all, but I dont know how to JTAG.
Could you give me some video tutorials or step by step instruction on how to do it for my phone? Also what JTAG hardware and software do I need?
thanks :]
