There are 2 ways I can think of to fix this. One way is to charge the phone with the wall charger first. Hold the camera button while pressing and holding the power button. This should put the device in bootloader while not plugged in to the wall and get the PC ready before connecting the USB to the phone. Make sure you have a full charge before you do this because it sounds like your battery died while flashing. If you do this, you should be able to get it connected to a computer long enough to flash it back to normal.
Seccond option, if battery will not charge in bootloader mode or when device is turned off, buy new battery and then follow steps above.
I hope this helps... I personally have never had this problem before.
No connection in bootloader mode
After a rom update has interrupted by 96% (and did not finish) I have no chance to connect my mda vario to my laptop. I still come to bootloader mode but no step further.
Have anybody an idea to solve this problem. Is there any other chance to get a connection to flash the rom again?
Many thanks in anticipation for any assistance!

I am having problems , my tablet will not turn on AT ALL into APX, CWM, or Regular mode.... It simply does nothing.
I have searched and read people flash NVFLASH again to get it to boot up, however I cannot do this as my computer cannot read it (It is not turned on in APX mode) So is it totally bricked now?
I've held the button down for 15+ seconds both volume + and - with power , I've tried re-plugging in USB to see if maybe the computer can read it (while AC cord is plugged in) The tablet has juice, it just will not turn on.
(This is after having bootloop issues)
Do you have nvflash installed?
Have you read this thread?
http://forum.xda-developers.com/showthread.php?t=1038689
Yes I read that thread, it does not help... When I plug the tablet into the computer, my computer cannot read it as it as the tablet is not in APX mode. When I try to turn the tablet on in APX mode nothing happens.
I also did the recovery as listed by http://forum.xda-developers.com/showthread.php?t=861950 "[STICKY][ROM] nvflash FULL restore, using bekit's original image (Instructions)" when I was having bootloop issuses, It returned the tablet back to the original stock boot sequence however it was still boot looping. Now the issue is it wont boot at all, it wont turn on whatsoever.
I read that other people were having an issue similar to where they thought it wasn't on, and they managed to plug it into there compuer VIA usb and force NVFLASH there tablet to work again, however I cannot do this as my computer will not recognize the device is plugged in without the tablet being in APX mode

+1 you should Try another PC answer if it is an error with your PC. Have you had it plugged into USB while trying to power cycle with power & volume - ?
Yes I have tried it plugged into USB while trying to turn it on
if you nvflashed it to stock then you may be experiencing the original bug. Unplug it from any power source and let it sit for 2 days then plug it back in and try and power it up. There is a bug in the original software that would lock the tab until the battery was completely drained. Or you can take it apart and hit the reset button or pull the battery
Is there any tips for removing the back cover?
Any other suggestions??
Let it sit for 2 days is a good test too. This did happen with stock a lot.
FIXED IT!!! Took apart the G-Tablet and unplugged the battery and pushed the reset button a few times,
Loaded into clockworkmod and repartitioned 2048 and 0, WORKED!!!!
THANK YOU BABY JESUS
that would be "thank you thebadfrog"

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.
Hello, guys
I upgraded my z2 from 5.1.1 to MM. It's existenz v1.0.0. It worked good. I wanted to downgrade to Lollipop 5.1.1 . I entered TWRP and restored the ROM that I saved before. I press "reboot system" and then It totally backed out. It can not turn on. I pressed power + volume up, it didn't vibrate. I tried, tried... many times but it didn't work. I use the flashtool to downgrade. When I pluged the cable and pressed volume down. The red light just flashed, flashed and flashed and nothing happened. What is that problem. Can I save my phone anymore. Plz help.
Sudden death.

Have you tried pushing the red button for 5 seconds under the microusb cover flap to completely reset the system?
Does the device get recognised in the DeviceManager, if so have you installed the correct developer.sonymobile[com]/downloads/drivers/xperia-z2-driver/ drivers for it? (you could also try it on ubuntu)
Are you sure your connection / cable is good?
Have you tried to boot into theandroidsoul[com]/sony-xperia-z2-flash-mode-54084 flashmode? (volume down), does it get recognised then?

I tried the ways you showed me. Sadly, it didn't work. The cable I use is OEM. I connected it in flashmode to flash. It didn't recognize. The red light of the phone kept flashing. Maybe, my phone is completely dead. Thank you for helping me.

Ah, this doesn't sound too good. The good thing is that the flashtool works, but since it doesn't help you may try a method called "test point". But if you decide to do it, be very careful not to touch anything else with the paper clip (if you touch the small component with the metal surface there will be sparks coming out).

My phone is LB. The battery was about 60% plus at the time of restoring the LP Rom. I pluged it in to charge, but the red light kept flashing.
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

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
