Phone doesn't Show up for Fasboot - Sony Xperia XZ Premium Questions & Answers

Hi, I am trying to unlock my bootloader,
I got adb to work, my phone shows up when I run the adb device command and the reboot to bootloader, is also working but when I run fastboot devices nothing happens.
In device manager my phone shows up as android, for some reason I seem to be missing fastboot drivers.
I install the minimal adb & fastboot package.
Any help would be appreciated, thanks.

If you have already installed flashtool, try installing the fastboot driver in the flashtool folder,It seems to need to disable mandatory signature verification in order to install successfully. And have you turned on the OEM unlock button in Developer mode?

After the installation is complete, the flashtool folder will have a driver folder and try to install it.

OK sorted, thanks @HoiFung.

[Q] Stuck on Google logo. Unable to push image file to phone... Please help.

Tried various possible solutions and still can't get past the Google logo. Installed adb and Samsung driver but when executing commands such as "abd remount" or "adb push file.zip \sdcard\" in cmd I get an error saying "device not found".
Does anyone know how I could resolve this issue?
I tried clearing the cache and wiping the data from the phone, and even heating the phone with a hair dryer. I'd very much appreciate any help.
looks like you still be able to get in reovery ? if so , then nothing you should worry , just flash a new ROM
Do you mean like a boot image or a recovery image?
If so then you need to put phone in fastboot mode, hold volume up and power til it comes up on screen, then on command prompt on your computer type in fastboot flash recovery xxxxxxx.img (xxxxx is the name of the file like cwm5.0.2.0.img or whatever)
That should give you a working recovery to flash roms from.
Is your boot loader unlocked?
If you wanna mount then just go to mounts and storage and mount USB storage and it will show up on your computer!

Thanks for your reply, seems to be hanging on waiting for device. Fastboot appears to be locked and it just hangs on "waiting for device" when I enter the command fastboot oem unlock... Not sure where to go from here.

Hmmm try going to cmd prompt and typing in adb devices, if you get nothing then your adb isn't set up properly and you need to go into setting and change the path on your computer.
I know the details are sketchy but gimme a min and I will find you a link

Find the Android sdk folder in your computer, move it to the root of C.
I don't think adb is where this guide says it is, there is a read me in the folder where it was saying it has moved to the platform tools folder.
So anyway find the path to the file and put it where the guide says and you should be on the ball.
Forget adb. You need to use fastboot.
Open a command prompt in the directory with fastboot or cd into it.
Put phone in fastboot mode.
On the command prompt type fastboot devices.
You will see your serial number. If you don't recheck and make sure you did everything. Sdk PDA drivers if need be etc.
Fastboot flash recovery custom recovery img name.img
Boot into recovery
Mounts and storage.
Mount SD card
Put a rom for you device on there.
Unmount
Wipe everything but sdcard from recovery.
Flash the rom by going to install zip from SD card......
Okay still stuck trying to connect to my phone. I haven't been able to get my serial number show when typing fastboot devices in cmd. adb is set up and seems to be working but the list of devices is blank when I type in adb devices. The phone was put into fastboot mode both times. I get <waiting for device> when I try
fastboot flash recovery clockwork-5.0.2-crespo.img
I think the bootloader may be locked as it does say LOCKED under lock state, which is probably the reason why I can't get the recovery image to work. I couldn't install PDANet as it wanted to connect to my phone while in debugging mode at the end of the installation. Would it be possible that fastboot oem unlock won't work with without having PDANet installed? I'd really appreciate any further help on this topic.
You need the drivers.

I have the Google USB driver package installed from SDK Manager. I had tried to install some other Samsung driver found on another post but it wouldn't install.
Turns out drivers weren't fully installed, managed to get PDANet installed and could connect to the phone with fastboot devices. Serial number was displayed in cmd. Only problems lies with unlocking the bootloader. fastboot oem unlock fails giving an error: too many links. Anyone have a solution to this?

Did you try booting into bootloader in the first place? Volume up+Power
Then you can use fastboot. Forget PDAnet. Just install SDK and ADB

Yeah I was in bootloader at the time, but I noticed that the Lock-State said locked. So I figured I must first use fastboot oem unlock. If I was to try flash with a stock recovery image would I still need to unlock the bootloader? Like I said I was able to use fastboot devices and get my phones serial number to show up, so I think SDK and ADB is properly installed, path set correctly etc.

I don't think you need to unlock the boot loader to flash a recovery image.
I may be wrong but I remember someone saying that once. I had mine unlocked before I had the chance to try it out. What happens when you type in fastboot oem unlock?

Thanks for your reply, I followed the steps just now and got the exact same error. Before I was trying fastboot oem unlock while in platform-tools but this time I had downloaded the nexussrootICS.zip file, and extracted it to the root of C. I tried fastboot devices and my serial shows up and after fastboot oem unlock I get "status read failed: too many links."
The only difference I seem to have is that in my device manager I have Android Device > ADB Interface, as opposed to SAMSUNG Android Device > ADB Interface.
Not a big difference but that's all I can think of.
the same issue for me. is there any working solution for that?
I recently had success in recovering from this issue.

[Q] Fastboot and locking problems

hey so i need to send my nexus s in for repair and i have stock rom and recovery, but every time i try fastboot oem lock it just sits at "waiting for device"
ADB works fine.
I tried alternative drivers
What can i do to re lock my phone?
Are you in the bootloader? (Phone off -> Vol. Up + Power -> fastboot oem lock).
Also, does the command "fastboot devices" show your device?
The USB connector socket at the phone might not make a proper contact with the USB plug. Make sure they connect properly. You may try another cable, or have a look at your USB socket and compare it to another. Check out particularly the little horizontal part in the USB socket.
Make sure you're in bootloader/fastboot mode before attempting to connect in fastboot. Fastboot cannot detect your phone, make sure your udev related settings are appropriate. Check on a Linux PC: https://source.android.com/source/initializing.html Configuring USB Access section.
If after this your phone will not be recognized by fastboot, please post the output of the following command (as root), after seconds after connecting the phone in fastboot mode:
Code:
tail /var/log/messages

fastboot does not show my device. I go into bootloader using adb reboot bootloader because my stupid power button wont work, thats why i want to sent it in to get fixed.
If drivers are properly installed this might not be working because the power button is stuck in or something. Not sure what to try to sort it out if that's the case.

1 - Boot your phone into fastboot mode.
2 - open cmd in your pc.
3 - write: cd \"name of the file where your fastboot is in your pc", and then press enter.
4 - write: fastboot oem lock
5 - press enter and it's done!

Hi, I know this thread is old but I was having the same problem relocking my nexus 4 after installing stock Android 4.4.3 KitKat.
I'm using Nexus Root Toolkit, I don't know what tools you're using to lock your nexus S boblem ut this very easy to use it downloads the drivers and what ever you need to lock, unlock or flash stock and custom roms for any Nexus device.
So my problem was that I would launch OEM Lock on Nexus Root Toolkit and it would detect the device, reboot in Fastboot mode and it would proceed just fine but after saying "Launching TWRP.... something" it would reboot the phone and say to me "Waiting for device" untill it would time out.
I found out that when the program(NEXUS ROOT TOOLKIT) asked me to download a TWRP IMG files, I said no everytime because I didn't think I'd need it. So after trying 5 times, I allowed it to download it and i retryed to OEM Lock it and MAGIC!
Somewhere in the process of Locking the rom it is going to need the TWRP File so allowing the program to download it solved it for me.
I don't know if this will help you or if you still have the same phone, but if you do have use Nexus Root Toolkit and download all it asks and you'll be fine.
Good Luck.

I have the same exact problem.
ADB works fine when the phone is up & running, so I am suspecting a driver compatibility problem when the phone is in "FASTBOOT MODE".
I tried to install the "Universal Naked Driver 0.73 (Compatible with Nexus 5, 4, 7, 10 and S)" but Windows 7 64-bit refuses to pick it up. I use the Device Manager method which shows (when the phone is in "FASTBOOT MODE"):
Code:
"Other Devices
> Android 1.0"
When the phone is up & running, Device Manager shows it as:
Code:
"Android USB Devices
> SAMSUNG Android Composite ADB Interface"
Any idea how to proceed from here?

Well before trying to Relock the device see whether its connected or not. Type this command fastboot devices and hit enter see whether it shows some no. As in a reply if not that means the deivce isnt connected. If the device is connected type this command to relock your device fastboot oem lock and hit enter. Check on your device screen The Lock status will be changed to LOCKED.

Locked bootloader but with TWR and rooted.

Two days ago, I unlocked my bootloader and it wiped everything. After that, I installed TWR and rooted the device with a toolkit.
Now I don’t know what went wrong, but I would like to flash CWM recovery instead of TWR, but...
it’s now showing that my bootloader is LOCKED.
And I cannot unlock after I’ve tried using adb, cmd, or the toolkit.
I will hold Vol Up+power to enter fastboot and as soon as I hit “unlock bootloader” or enter “fastboot oem unlock” in command, the phone immediately starts into TWR.
Without an unlocked bootloader, I cannot flash anything via the bootloader.
Any help would be appreciated. Thank you!
Turn the phone completely off. Hold volume up + power, plug the phone in via USB (ensure that you have the drivers installed for the phone)
fastboot oem unlock
fastboot reboot
then go back into volume up + power (fastboot mode)..... fastboot flash recovery <recovery-name>.img while the recovery file is in the fastboot.exe folder. then boot into recovery.

You see, I cannot even get to the part where I reboot the phone myself because the phone automically does it for me and jumps itself into TWR recovery and does not unlock the bootloader for me.
It takes less than a second from when i run the command "fastboot oem unlock" to when the phone reboots. Then it take about 15 seconds to get to the TWR recovery.
The only drivers I've installed on my Win8 (tried Win 7 as well) are these:

Silly to ask, but you unchecked the cm update in dev settings and enabled debugging?
Personally, my second lappy didn't even list the device in fastboot, but the commands still worked.
I would just boot into fastboot and run the all the commands in series.

Hi lemonspeakers,
sadly I don't have a solution, but the same problem.
Current state:
Bootloader locked
TWRP installed
no root
Sending "fastboot oem unlock" causes reboot to recovery.
Besides that the phone is fully working. (My friends thing I'm crazy because I'm sad about a fully working, "normal" phone
I hope somebody have suggestions to fix the issue.
Update:

I could fix that by going to Recovery, factory reset, reinstall SuperSU an reboot. My phone now is finally rooted.
I think the factory reset part is strange, but I'm so glad I now have a rooted OPO.
When you try it, please let me know if you also have to do a factory reset.

ok now I'm confused.. those drivers didn't work. following the root guide on here it says 'unlock the usual way''boot to bootloader''issue command 'fastboot flashing unlock''
so I decided to try rebooting to fastboot instead, which brought me to fastbootd
fastboot does recognize fastbootd, but the unlock command "flashing unlock" is unrecognized
So do I use bootloader or fastbootd to issue the unlock command?
if the latter, why would fastbootd not recognize the command?
the 'oem unlock' option is ticked on...

fastboot does recognize fastbootd, but the unlock command "flashing unlock" is unrecognized
So do I use bootloader or fastbootd to issue the unlock command?
if the latter, why would fastbootd not recognize the command?
the 'oem unlock' option is ticked on...

Make sure you enable oem unlocking in dev options first and reboot.Reboot to bootloader,issue command $fastboot flashing unlock..

Are you a carrier variant or global unlocked 9/9pro?
OEM unlocking is enabled, reboot to bootloader, command 'fastboot devices' shows no devices
Still have unknown android device in device manager
It's a global unlocked 9

Did you create a shortcut to those adb driver's when you installed; on desktop. And open cmd window in that spot. ?

I'm not sure what you mean by shortcut
I unzipped the file to my desktop, then tried installing driver through device manager, but no driver was found.. I then tried installing the driver with the "DPInst_x64.exe" file, but it says install failed with no other explanation
I tried just opening a command prompt in that folder, but with no driver installed, it still isn't recognized
Thanks for helping, I'm lost at this point lol

Try one more thing. Install these and creat shortcut on desktop and try opening cmd in this. We gonna get you unlocked.
One last thing. You have also went into developer options and tic'ed "USB debugging on then ok on device when it asks if you wanna allow phone to communicate.
tried that, still nothing. usb debugging is on.
all I need is a working driver, everything else should be good..
one thing which i'm not sure if it's an issue, I'm using an old usb c to usb 2 cable, I'm not using the cable that came with the phone because my computer doesn't have usb c ports.. but adb and mass storage/file transfers work with no issue
Hate to say it, but it still COULD be your old USB cord even with file transfer and adb functionality preserved. I had a cord that did do file transfer but not adb. You should try another cord...
Here's another driver source to download:
Universal ADB Drivers
2 new cords, and also tried multiple driver downloads, but still nothing... i was really hoping to root this phone and it seemed so easy for everyone else, thats why i bought it.. but I guess I'm stuck with a locked bootloader...
I could try factory resetting windows or the phone, but would that even make a difference?
..rereading the root guide, at the beginning it says "if you're on global and want root, flash the eu boot.img" but I'm not sure if he means do that first or use that for the guide.. I'm assuming I need the bootloader unlocked in order to flash it first, but maybe not..
..also should I have just commented in the root guide post, instead of making a new post?..
I'm sure you've tried another usb port on your computer.
Last thing to try: another PC.
Shouldn't come to that, but that's where you look to be.
Got it!! Someone posted about the op6 not working either and the fix is turning off windows driver signature, not sure why but that worked for me..
Thanks, now on to root lol
I just had some serious fastboot driver issues when setting up my oneplus. Not sure if this helps but can you at least find the driver folder that was installed on your c:drive when you initially installed the drivers. Then check your device manager when your phone is in fastboot and update the device (usually under portable devices) through that path?
If you get a tampering /corrupt error when you do this you can disable driver signing in windows which is what worked for me thanks to this saint.

You sir are saint...I've been trying to get fastboot to recognize my OP6T for the last 8 hours. Thank you so much!
