When I go to fastboot mode, I can't use it. I type fastboot devices but I get blank screen.q I install drivers and I can use adb from WinXP and Linux.
What to do?
Thank's in advince
Use the latest fastboot binary from the android sdk (linux). On windows you might need some driver hack that is floating around here somewhere.
€: For windows: If adb is working you should also be fine eith a recent fastboot binary.
I installed drivers and downloaded lastest sdk(you have it in first post).

I was messing about with the same thing. When you type fastboot devices it can give strange answers. Mine came up with: ? fastboot. When i typed fastboot devices. So i kept looking and uninstalling and installing and always the same answer. So i tryed to send some commands to the folio and Viola! it was connected. But if it dont answer you just have to follow this guide on setting up ADB and Fastboot http://forum.xda-developers.com/showthread.php?t=915894 Good luck
If I understood,I must install drivers when I'm in fastboot mode?

It is the same driver/udev rule that adb uses, so if adb works, fastboot should also.
I was trying to unlock the bootloader in my Atrix but I can't seem to get the fastboot to work.
I'm running Ubuntu 10.10. The adb works perfectly and when I run the fastboot command it gives me the list of syntax for it but when I try "./fastboot devices" it doesn't return anything. If I use sudo then it goes down to a new line and freezes. I'm assuming I need to edit something in rules.d but I don’t know how to get the proper information.
Any help would be great.

is your phone in fastboot mode? adb reboot fastboot
If it freezes at devices it can't see you phone. Make sure your phone says it started fastboot. Hold volume down while booting. When it says fastboot on the phone press volume up.

Well I tried running the unlock in fastboot mode last night.
./fastboot oem unlock
Waiting for devices.
That was as far as I got. My phone was in fastboot mode but it just wouldn't recognize it. I saw some other posts about it saying things about adding to rules.d but I need the right information for my phone.

Try checking if fastboot is connected wit \
Code:
fastboot devices
If not then try to reinstall fastboot drivers or connect/reconnect ..
You just install "flashtool" for your pc then you connect your device to pc ( it must to be on flashboot mode) then flash the kernel you want. It easy and nothing problem

I am following the official guide [*1], which is suggested from this root instruction[*2].
But I keep getting this error:
Code:
C:\fastboot>fastboot.exe -i 0x0fce oem unlock 0xMYKEYGOTFROMSONY
...
FAILED (remote: Command did not succeed)
finished. total time: 0.021s
What could be wrong? Is there anyway to get more debug information to see why it's failing?
Here is my settings:
Phone model: D6503 / Xperia Z2
OS: Win 7 64-bit
USB Driver: Android Bootloader Interface version 4.0.0.0 [12/6/2010]
(This one is using android_winusb.inf dowloaded from Sony official site, and the rest files from latest Android SDK (64-bit)[*3].)
In the service info > Rooting status: Bootloader unlock allowed: Yes
Running this cmd:
Code:
>fastboot.exe -i 0x0fce getvar version
shows "5.0".
I didn't insert the SIM card while unlocking.
The phone USB debugging mode is enable already.

If you run "adb devices" from wherever your adb.exe is, does your phone show up? That's a good way to test if your USB drivers are working.
Download latest flashtool and install all drivers again and then use flashtool folders to use USB might work out better for you

i think you shouldn't show your unlock key to us
He didn't.
@JMonkeYJ: I ran adb.exe with my Z2 phone in fastboot mode, but it didn't find any device.
@festa20: I downloaded flashtool-0.9.16.0-windows, installed it.
- then run flashtool\drivers\Flashtool-drivers.exe, install below drivers:
Flashmode drivers, fastboot drivers, Xperia Z2 Device Drivers.
(But when connect Z2 to the USB in fastboot mode, in Windows 7 Device Manager, it still shows:
SAMSUNG Android Phone (my old phone was a Samsung):
Sony ADB Interface (Driver Provider: Google Inc., Driver data: 12/6/2010, Driver Version: 4.0.0.0)
Looks like the ADB driver is still the old one I installed, not from the flashtool(?)
- I then run flashtool\x10flasher_lib\fastboot.exe in command line, still got same error...
Looks like it's a driver issue, how do I install the correct driver?

If your device is plugged in to PC in fastboot mode you need to do "fastboot devices"

I get a similar msg.
Running SDK from Linux (Tiny Core)
fastboot fired up fine
But got similar message after following Sony step-by-step.
./fastboot devices
then tried
./fastboot -i etc.
RESULT:
FAILED: (REMOTE: Command not allowed)
Any ideas?
Is there a different tool I should try another utility?
This Z2 is a Verizon release...and I noticed Sony site mentions some Z2 devices cannot be unlocked.
Is this an evil empire block?
Help!
I have problem just like OP. How did you fixed it?
Bootloader Unlocked Allowed : Yes
and fastboot working, detect my phone.
I already tried with 14,15 digit IMEI but result are same as the output bootloader key is same
I have issue using this method as well as trying to use flashtool. Both doesn't work. For fastboot I get into the command prompt and it's just stuck on waiting for device. In flashtool it can't find my device and tells me to reboot the phone. Any ideas? BTW my phone is rooted does that have something to do with it?
you cant adb bootloader unlock unless you have added/modded some adb files
(only aplies to z2 btw)
(yes fastboot and flasmode too you need the files(try developer.sonymobile.com)
try flashtool from flashtool.net
install drivers first before trying

Still don't work after downloading again. Anyone else got it working willing to help out? I've tried going through Sony developer again and it doesn't work. BTW my handset says bootloader is unlockable.

have you got the drivers, adb files, adb installed with fastboot n flashmode and do you have the files for those
you can get all these files from sonymobile or adb download
of course you can try the easy way to unlock which is USING FLASHTOOL

ive got the same problem is there any chance you could help me please? its been driving me crazy trying to do this lol.
My PC doesn't detect my phone when I use Fastboot Devices when my phone is on Fastboot mode. I get a blank space in return. Can anyone help me with this? ADB works fine, it's only Fastboot. Is there a Fastboot driver that I might be missing?
Thank you.
Edit: I'm trying to unlock the bootloader of my phone.
Me too !
Drivers are here: https://developer.android.com/studio/run/win-usb
These are the ones I use for ADB/Fastboot.
May I ask if anybody solved this already?
Having the same issue, tried various drivers, but fastboot won't find my phone
Help is highly apperciated!
Clock
If you using windows 10 have you disable the drivers signature verification.. And search on here (XDA) for Min ADB & Fastboot tools, easier than using SDK tools unless you modding apks ect..
Okay, I got this working.
When in fastboot mode, you have to go to the device manager, update driver, and manually choose the google fastboot driver. Then the ! is gone and it works.
