[XU] Unable to get Fastboot mode - Sony Xperia P, U, Sola, Go

Hi guys,
I know that here is a lot of infos regarding this, but I cannot get Fastboot mode on my XU. To get Flash mode is no problem (VOL_DOWN + cable), but I cannot get Fastboot mode (VOL_UP + cable). Am I doing something wrong?
a, turning phone OFF
b, plugging USB cable while pressing VOL_UP button
It's Xperia U. I tried to do it appr. 20 times but without success, phone is allways getting only chargin icon with red LED on right upper corner....
Thx

Does your phone boots?

Yes of course, everything is working OK except ability to enter Fastboot mode... That's why I'm asking if I'm doing something wrong or where's the problem... I want to unlock bootloader through Flashtool (I received unlock code from SONY by mail). But to do that, I have to connect phone in Fastboot mode

Brfore turns into charging mode is it light the blue colour?
Sent from my xperia sola using xda premium

No no. It's going only red (small LED in upper right corner) and I receive battery icon on screen. Is possible that I cannot enter Fastboot mode, because I have "Bootloader Unlock Allowed=NO"? But now I'm thinkning that my question is useless, because if my option =NO, then I'll be not able to unlock bootloader, even if I received official unlock code....

This phone will exit fastboot mode if you dont have the drivers installed correctly. You need to be fast to install them before the phone exits the fastboot mode.
Also you need to have your bootloader unlocked or it will not work.

1. Disconnect phone from USB
2. Turn off phone (make sure you have at least 50% battery) and wait 30 seconds.
3. Hold the 'Volume UP key' WHILE inserting the USB. --> LED turns blue = fastboot mode.
4. Leave the phone turned off
have you install drivers for fastboot from sony ericssons site? and you dont have to power up the phone press Volume Up and at the same time conect usb cable

rooting the phone should not affect the sound settings.
Did you check the sound options?
Xloud turned on?
I cant get my mini pro sk17i into fastboot mode. Tried waiting more than 30 seconds before plugging in usb cable, nothing.

I don't have SK17i, did you try holding the menu button instead of the volume up button? as they are different models.

You can try wwwong's suggest, or basically just try all the buttons on your phone. The design may be different between models, but you should be seeing same blue color LED when your phone is is fastboot mode

Is your phone turned off? Look at the video above. It's the same general rules but different buttons are used.
I am having the issue, obviously our phones are branded... I THINK i might have actually unlocked the bootloader using S1TOOL with TP, but cant manage to get into fastboot... Is there any way to get around this issue anyone? And yes i have done everything right trying to get into fastboot...

Same problem
If you do not get blue led that means fastboot is not enabled I can enable fastboot and then unlock your bootloader for you.

[Q] Indication of fastboot mode

Hello guys,
I need help on checking whether an Xperia U has fastboot enabled (bootloader unlock allowed) WITHOUT booting up the phone and check in the service menu.
I know that fastboot mode is indicated with a blue led.
My question is this: if I connect the phone while holding the vol+ to a PC that doesn't have fastboot drivers, will the blue led still light up?
The store doesn't want to boot up the device normally, as the phone would ask for customization
Thanks!
It should light up, but why don't you just show the sales people to the data wipe button?
Thanks man, I'll let them know

Problem in unlocking BootLoaders for Sony XPeria Sola

I read the "How to Unlock BootLoaders for Sony Xperia Sola" by "DooMLoRD" today & tried to unlock my XPeria`s bootloaders but failed.
I did everything right but failed to call the fastboot mode correctly.
I pressed & hold Volume Up key of my Xperia Sola & plugged the USB cable in, the phone started showing the blue light, i.e; it was connected in fastboot mode but after 2 seconds Sony`s logo came up on screen & the phone was disconnected from fastboot mode ( the blue light disappeared ). And the phone started normal charging.
Can anybody please help me, how to resolve this issue.
Thank You:fingers-crossed:

Hold the vol+ button for a longer time
I have tried that but it does not work...
As soon as Sony`s logo is displayed the phone gets back to normal.
try installing fastboot drivers from another source and make sure u have android sdk (fastboot drivers is included in tools or download it using sdk manager) along with google usb drivers.
replace android-sdk\extras with this
http://dl-developer.sonyericsson.com/customROM/windows/downloadinf.zip
try fastboot again (if asked for drivers, point to this file
I have the same problem. What am I missing here? I have SDK Tools on & I keep my vol + (tried Vol - as well) Plz I need help cuz I want my sola rooted!

Sony XZ1 G8431 bricked

Hello guys, i have sony xz1 g431, i bricked my phone when i try to install another rom of another device via twrp. Now my phone no light when connect to pc, no light when charging, flash tool doesnt recognize my phone. When i connect my phone to pc it only shows QUSB_BULK on my pc. I think it lost fastboot or something. I try hold down button, up button or both when connect to pc but still no light and nothing happen.
Please help me fix this problem or atleast some good suggestions to solve this problem. I will really happy for that. Thanks :crying:
Just have the phone powered off, hold just only the volume down button and while holding it, connect the phone to usb cable to your PC.
It should enter flash mode (green light), where you can flash stock firmware via newflasher (or possibly also via flashtool, but I do not use that).
If you have the phone off, hold volume up button while connecting to usb, it should enter fastboot (blue light), which also may be used for some recovery, if the phone has been unlocked (or for the unlock itself).
If any of those modes are available, the phone should be possible to recover.

i have tried it but there's no light. I think it's dead :crying:
@Karl Einstein, have you tried both ways as suggested above?
Maybe you can examine what usb device appear (if any) in each of the described modes (tried to enter flash mode, tried to enter fastboot mode, tried to just plug the phone to usb without holding any button from power off state).
What happens if you try to enter recovery mode (twrp) - having your phone powered off, without usb connection, holding volume down and power, should enter twrp if you had it flashed before.
Do you get any vibration when hold the power button and.volume.key.up?

Well...I think your phone is dead...I'm really sorry to say that, but in this case, that is the only reasonable explanation.
Yesterday I flashed the GSI image, then tried to flash to eXistenZ, it just stuck in the startup interface. However, it can still enter flash mode and fastboot mode, I have no choice but to use the newflasher to re-flash the firmware, it will return to normal.
In general, Sony devices are hard to change bricks, unless the phone is a Japanese carrier's custom phone (generally can not unlock the bootloader, and can only flash some firmware).
I have seen users who have flashed CE firmware for the docomo version and then can't enter flash mode and fastboot mode.Unlike your device,her phone is totally dead...It can't be charged, and there is no prompt to connect to the computer.
If you can buy a motherboard from eBay or somewhere else,you can disassemble your phone,then replace the old motherboard.
Hope these helps.
Thank you guys for all your support. Finally i decided to skip this problem and i will buy a new device

Just a side note , why flash existenz on a gsi rom... As it is made for stock Sony only or did I just misread something..
I had the same issue before on my lenovo p2 it lost fastboot and download mode but the PC detect it as qusb bulk then Qualcomm USB h9008 I searched all solutions but no good I think it needs some kind of box to push the modes or change the mother board. So I changed to Sony instead of repair it

Sad to ear that...
I had the same issue with my previous Htc10.
As it was still under warranty, I have had to contact HTC support and told them that and OTA bricked it.
They accepted the issue and replaced the motherboard.
I was BL unlocked, rooted and custom rom when it happened and no issue with support as they had no mean to prove it ?.
If still under warranty try to contact Sony support and tell them the same story... Ota bricks my phone ?

I've flashed eXistenZ before flash GSI in my phone. I thought GSI image would cover my origin ROM like eXistenZ, so after flash GSI image in,I flash eXistenZ again.

I have the same issue. My sony xperia xz1 G8342 got sudden dead. (Before dead, I remember I disabled "Developer Mode"). Now its not response by any mean except charging sign when i connect to Power source or PC. Xperia Flashtool shows "device connected with USB debugging disabled".
So, How Can I enter flash mode or fastboot mode? Is My phone recoverable? Please Help.
Thanks
Yesterday I was struggling with my XZ1 Compact and came across this thread that gave me some light to get my mobile phone back.
I guess it's way late for Karl now but just in case, I'm sharing my experience. I was working on my device to get LineageOS 18, as I'm a total newbie with roms I followed the different articles that were posted on Getdroidtips for this particular case: Unlocked bootloader, flashed TRWP and installled lineageos. But then I realized it would be good to have Google Play for restoring my files and apps, but when tried to reboot into recovery mode to get Gapps flashed, Black Screen Of Death started.
After that
with the phone plugged to the pc it wasn't recognized as a device (so adb or fasboot where useless)
the only thing the phone reacted to was to press and hold power + volume up (either for reset or power off)
but no matter what, next boot again BSoD
Tried the Xperia Companion but it prompted that repair was not possible as bootloader was unlocked.
Eventually found this life saver

From there, using fasboot I could reboot the device back with the LineageOS. I was still having issues with recovery boot but I'll post that on a different thread.
Thanks again to everyone for sharing thoughts and tips!

Sony Z Ultra - C6883 Unable to get into fastboot mode

The phone has been in the drawer for quite a long time (5+ Years)
I come to try flash root to it and it wont boot into fastboot. all that happens is a black screen and nothing else.
ADB reports it as being there till it reboots ( 'adb reboot bootloader' ) , when the phone reboots its a black screen and if i plug in a usb lead then i get the standard windows was unable to recognise this device. ( Attached is a device manager Grab of it )
I have tried to use Flashtool64 (latest version) it reboots to the same black screen. The only way then to get it back to a usable phone is to unplug the lead and press the power button till it vibrates.
I have spent 10+ hours reading and reading everywhere and nothing that has been suggested has been succesful.
This is my last hope ( I realise its a 10 year old phone) and am hoping someone can help me sort this out.
Many Thanks in advance
You wrote nothing about the version of adb and drivers you are using.

Tried that.i have spent a very long time on this. Starting to get to the point that the phone is poop. And needs to be binned
To confirm the functionality of the equipment.
Can you transfer files from/to phone in adb mode?
Yes, the device problem only happens when it reboots to bootloader for fastboot access. I think bootloader is corrupted . Can't flash new one without boitloader/fastboot access. Well that's my understanding
What about flashmode?
Flash mode:
1) Connect the USB cable to the computer (do not connect it to the phone yet)
2) Turn off the phone
3) When the phone turns off, plug the USB cable into the phone and hold the Volume Down button
4) The phone should boot into Flashmod mode!
Your Xperia Z Ultra should be in Flash Mode now and the device’s LED light should turn into Green
Fastboot mode:
1) Connect the USB cable to your computer (don't connect it to the phone yet)
2) Turn off the phone
3) When the phone turns off, plug the USB cable into the phone and hold the Volume Up button
4) The phone should boot into fastboot mod!
Your Xperia Z Ultra should be in Flash Mode now and the device’s LED light should turn into Blue

Same. Even EMMA doesn't work. Which was a suggestion. Or flash prog (used old and new) all seem to reboot to bootloader/fastboot which has same error as stated.
The usb vol down with plugging in usb / power on doesn't work either.
neither does the vol up + power / usb
ammended to clarify
when powering up/vol down i get a short vibration, then it boots normally. pressing vol up + power gets black screen.
usb + vol Down does nothing, usb + Vol up also does nothing
I am thinking that the phone is not booting into a software that 'tells the USB what it is. Th OS boots fine tho and it sees the phone and can xfer to and from the phone
