You need drivers on the PC for the device (ADB drivers I think). I forgot how I overcome this problem last time lol, sorry. This should however be of some help : https://forum.xda-developers.com/showpost.php?p=61227900&postcount=3

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.
So my friend picked up a broken Z Ultra for god knows why, and he's asking me to fix it.
I first test the device by connecting it to the charger, it boots. Alright. But it won't pass through the battery screen. Upon holding the power button the device vibrates 3 times, screen goes black and restart again as if the device was forcefully shutdown just like any other Xperia devices.
I connected the device to a computer, it went straight into fastboot mode. I thought, "Alright, this device should be locked, let's unlock it." Nope, it was unlocked, the fastboot responded with FAILED: "the device has already been rooted." So I booted the device into flash mode, and flashed the C6802 14.4.A.0.108 FTF. The flash process went fine.
After rebooted, again, same issue. It doesn't pass through the charging screen, if I hold the power button it'd just shutdown. Where do I go from here?
And yes, I can't access recovery mode either it seems.
Try and flash a cm/etc boot.img to the device and then flash the same ROM the boot.image came from
Hello.
I might have hard bricked my phone. I wanted to give my phone to warranty repair so I did S-OFF (Rumrunner's method), flashed stock t-mobile ICS rom, recovery and kernel. Everything booted up, so I had to lock bootloader and S-ON. I tried locking bootloader with method described here. To be precise I locked it via fastboot oem lock (but it showed relocked instead of locked) so I wanted to unlock it with this method:
http://forum.xda-developers.com/showthread.php?t=2470340
after I did all of this, the phone wouldn't reboot.
There is black screen. LED light is orange after plugging it to a charger. I tried taking battery of and even replacing it with another one. The only thing my phone does is 7 vibrations after:
1) plugging it via usb cable to wallcharger/pc
2) pushing power button
3) pushing power button and vol. down
screen does not turn on, LED does not turn on, phone is not booting to bootloader :/ Any thoughts guys? I'm begging for help
I have been reading posts for days in multiple Xperia forums here trying to identify my soft brick condition.
I had a bad flash using flash mode, and the device just keeps power cycling with no logos. I turn it on, and I receive one "buzz" followed by a red light, then a green light, then it goes back off.
If I hold vol down for flash mode, this just repeats over and over.
If I old up for Fast boot, it does go into fast boot, but this is a VZW locked boot loader, and I can not do much in fast boot mode due to these restrictions.
If anyone knows a hack to unlock the boot loader or some other way to fix the flash mode so I can re-flash, it would be greatly appreciated!
When the read and green leds are going off ypu should be in flashmode
Look on your pc device manager and ypu will see the device therw
When the red light flashes, it buzzes, then the green light comes on for a brief second, then it reboots immediately and I never see the device show up in device manager. The Flashtool also never recoginzies the device either while it is in this cycle of kernel rebooting (I assume it is just the kernel attempting to boot since it can go into fastboot).

Hello guys,
I upgraded my unlocked bootloader E2333 to 26.3.B.1.33. I have spent hours trying to boot into fastboot but it always fails. When I connect it and press vol up, all I get is the blue led for only 2 or 3 seconds and then it changes into red and sony logo appears. I found a lot of topics in this section about that problem but none had the solution. I just want to root it, but without fastboot I can't even flash the recovery!
