Fastboot device not recognizing.Need Help! :( - Android Q&A, Help & Troubleshooting

Hello XDA members
My device is Sony Xperia ZR and I'm in big Trouble.My phone somehow soft bricked without touching or modifying system after reboot.And now I can't flash stock rom via flashtool because It's not working but my phone still can go to fastboot mode.Unfortunately pc not recognizing fastboot devices but I properly installed adb drivers for my device.So I can't do anything to recover my phone.This is very confusing why pc not recognizing my phone even after my phone can go to fastboot mode:crying:.My usb cable is fine so I can't blame it.Any suggestion would be appreciated.

[Q] Xperia U Hard Bricked

Hi there,
I have a rooted xperia u with unlocked bootloader. I've tried to install the cm9 following a guide where the requirement of the installation was having an original Sony firmware installed on the device. I didn't saw that requirement, and I installed it with a custom rom on my phone. So after flashing the kernel I turned on my xperia...
Bricked.
It made only the vibration but no Sony logo appeared. So, I connected it in flashmode on my computer (with windowsXP) with green led working, but flashtool gived me the message that I must install the phone drivers (even if I had already installed them on my pc). I tryed to reinstall them but nothing canghed.
I also tried to connect the phone on a windows 7 pc always with flastool (and drivers installed) but in that case neither fastboot mode or flashmode, nor any vibration was working (pc doesn't detect it).
I tried to connect the phone with removed battery or also a reset with power and volume up buttons but nothing...
It's still like this, with fastboot mode or flashmode not working with any pc... :crying:
Is there anything that I can do?
Thanks in advance.
Head to Sony service centre
Hit thnx

Sorry Cwikla, I didn't flashed the kernel, but the rom. I wrote it wrong.
Try getting into fastboot. Even without drivers, you might be able to do so. Bring up the fastboot menu in flashtool, then plug in your phone in fastboot. Quickly hit reboot into fastboot (via fastboot). Then flash another kernel and restore a nandroid backup(if you have one)

[Q] Bricked (Cant boot, turn on the screen)

Hey guys,
So I wanted to try out the newest CM12 ROM with A5.0 but seems like it didnt exactly happen how I wanted it. Rooting the device and then installing the XZDualRecovery without a problem. Then downloaded the ROM and gapps.
I have SGP311 (pollux_windy) so I downloaded that version of the CM12 at first. It said that my device is pollux, which I ofc was dumb enough to just skip and download the pollux ver and then install that one. So I installed the pollux ver instead of pollux_windy and when I hit restart device I didnt see it boot again.
So I wanted to connect it to my PC, PC didnt recognize it ofc. Only way my PC regonizes my tab is by fastboot mode. I had to install a driver for that. And even then only the Sony Mobile Flasher by Androxyde recognised it. I run into bootloop various times before with my tab and Emma always fixed it but thats unfortunately not the case here as Emma doesnt recognise it either :/
So now here's the problem, I can only do fastboot mode (not flashmode) and the only program able to do sth with my device is this Sony Mobile Flasher. I downloaded a official FW there and wanted to install it but it required me to go into the flashmode which I can't.
Is there sth I can do? The only thing working is the LED and fastboot mode.
Is there a way to put the device into flashmode via PC, that would solve all issues or maybe a trick to go into flashmode? As there was some thread about it but the thing they did didnt work for me :/
Please help
Thanks in advance
Nevermind, I just forgot how to use Emma....
For anyone to whom this happens:
Computer: Open Emma from the Start menu of your computer.
Connect a USB cable to your computer.
Phone: Turn off your tab.
Connect your tab to the USB cable while holding the VOLUME DOWN.
Computer: Select the software you want to flash in the Service list. The tool automatically detects the tab and lists available software versions, which are called Services in this flash tool.
Click on Apply Service. The tab will now be flashed.
Phone: When you have flashed your device, you can disconnect your phone from the computer. The first time you start your device after you have flashed it, the boot-up might take a little longer than normal.

[bricked] Can't get back to stock

Xperia MINI ST15i
I have exhausted every method I can find. Fastboot seems to be broken. Fastboot and Flashtool both do not detect the device when it shows BlueLED(fastboot). PC Companion doesn't detect at all.
Flash Mode seems to be working. It seemed like it was flashing, progress bar and everything. When it was done it said for FLASHTOOL, the phone has to have usb debugging and unknown sources checked. Being that I am bricked, there is no proper system installed .
In FLASHTOOL & EMMA unlock bootloader doesn't work. I got the code for it to do in FASTBOOT or keypad but neither are accessible.
I believe I flashed a recovery for the wrong xperia model =/
Are there any other potential solutions?

[HELP] Soft bricked Moto E

Hey I hope you guys are able to help me, so onto my problem : it happened all a few months ago while flashing (can't remember exactly what) that my device won't boot it vibrates and then gets stuck at the M logo. I already went into boot loader and wiped cache etc: nothing. I have a locked bootloader status 0 and adb & fastboot installed on my PC, I charged my phone to 100% tried connecting it via USB but in the bootloader it doesn't change into transfer mode. It doesn't get recognised by the PC at all (im gonna try another cable in a bit) although it does charge through the USB port, as for the drivers I have the official Motorola drivers installed but to no avail.
Could it be that USB debugging is off due to me wiping everything and thus I can't connect via adb? How would I go about flashing in this case. Any help is highly appreciated you guys are my last hope

Bricked Xperia z2 flashmode usb not recognized but fastboot is recognized. Is recovery still possible?

So basically I suddenly got this system ui error which caused my phone to go into a bootloop eventually when starting up you could only see sony logo and it would stay on.
I tried to use xperia companion to do a software recovery but my phone would not be recognized. (the led does turn green when you press volume button down)
I tried using flashtool and installed drivers without driver signature but again when flashing it doens't recognize my device.
When the phone is in fastboot mode the device is recognized by flashtool. I tried it with 3 different pcs and 3 different USB cables and nothing.
I have never done anything to my phone so the bootloader is still locked.
I was wonder if I can still recover my phone but than via fastboot mode.
phone specs:
Xperia z2 d6503
os: marshmallow
kernel: 23.5.A.1.291
Thanks in advance for any help
