[Q] Fastboot Problem. - Xperia SP Q&A, Help & Troubleshooting

Hi there. I'm using Xperia SP for like 1 month now and I tried to unlock my bootloader. I'm using the Sony guide to unlock it (unfortunately I can't post a link (less then 10 posts :crying) . Anyway I've got one little problem while i'm trying to launch my Xperia in Fastboot mode.
The LED turns Blue for couple seconds, then it shuts down and the charging begins, like it's launching in fastboot mode and then turning off. I have Sony drivers installed from Sony PC Companion. I'm using Windows 8 x64. The system isn't asking for any drivers while i'm connecting the device to PC. Help me

Windows 8 x64 is a bad system for Flashtool to work with. I would suggest Windows XP....either through a VM or through dual-boot.
But if you have to use Windows 8 without a choice, please disable driver signature verification before you start Windows 8, so that you can install the driver successfully.
You wouldn't care where I sent this message from.

i have the same problem and i have windows 7 starter x86. all drivers installed. im wondering if my phone has fastboot mode or not.

Well everything works as I tried to do the same thing on VM with Windows XP. There was the same thing happening (the blue LED disappears) but after system asked me for drivers. After I installed them the device started to work as it should and I manage to unlock the bootloader . That surely was driver problem so if you manage to install them on your system I'm sure it'll work. Thanks for help

[Q] Fastboot mode problem - Xperia SP

Hi guys, got a slight problem with entering fastboot mode. I hold the volume-up key and connect me USB cable but rather than getting the noise verifying it's been connected ok, I get that dull sound it makes when it hasn't worked. It won't even let me install the drivers and in device manager it comes up as "S1boot Fastboot" for a few seconds before then going into battery charging mode. I downloaded the Android SDK latest and replaced the USB driver INF file with the one sony give you but it didn't work so reversed back to the other driver the SDK manager installs and that didn't work either.
I've been through the tutorials and even tried to update the driver in device manager in the few seconds it stays there but that didn't work either! USB debugging is enabled too!
Please help, I'm not a noob and have done fastboot booting before and yes for those who may ask have already checked to make sure the bootloader can be unlocked and yes it can also the phone is NOT branded and is unlocked to all networks.
Any help will be appreciated, thanks!
Dave.
Are you on Windows 8? Using USB 3.0?
"As your flesh bears the sigil....your name is that....of a recusant."
First be sure you're using a 2.0 usb port, if this is ok maybe it's a windows 8 driver problem, so you should try this http://forum.xda-developers.com/showthread.php?t=2170114. It works for me
For also fastboot and flashmode come for 5 Sec. So Make sure you prepare the file and attach the device to fastboot or flashmode when it is asked.
Still problems
I'm still working on a 2012 laptop with Windows 7 Premium installed. It's fully up to date and all the drivers are installed properly I just don't get it, I've tried everything and it's still making the noise as if it won't connect. I don't know what to do to be honest. Also yes it is USB 2.0.

Hmm...how many USB ports are being used when you're flashing the phone?

What I did was use a Windows XP machine.
Couldn't get it to work on my Windows 7/8, because of the restrictions in driver signatures.

I have a similar problem. the power light lights up blue then passes into the phone starts loading mode
Sorry for bad English
The updated version (09.14) don't work properly. It doesn't enable me to go to Flashmode. Uninstalled and used the previous version and it worked as it should, no issues entering Flashmode.
i might have actually found the solution. im on the 4.3fw build version 12.1.a.1.201... in my case, my pc will automatically install the drivers for mass storage giving me no chance to update the driver to the one from sony.
you need to do step 9. and 10. if you havent done so from http://unlockbootloader.sonymobile.com/instructions
what i did was allow developer settings and allow debugging via usb.
plug in and attempt to go in to fastboot and obviously it'll fail.
go to device manager. (control panel->hardware and sound->device manager) quickly scroll down go to other devices. you will see s1fastboot (or something like that) if you're quick enough, if not, in my case, the phone will go in to charging mode.
what i did was to disable xperia sp mass storage from disk drives category too.
right click on it and select update driver software and you will select the file you've unzipped (following step 9 and 10 sony's instructions).
after it has finished updating, unplug your usb and attempt to enter fastboot, it should work.
PS: im no expert, this solution might be out there somewhere already or it could just be a great coincidence. some of these steps might not be useful even.
Had this problem and found a funny solution: I switched my cable and the port I was using. Both Ubuntu and Windoze 7 failed on both fastboot and flash mode, even though in both the phone would charge. I grabbed a spare micro USB cable and plugged it into the front of the PC; voila. Now the phone is rooted and running the latest CM.
Need a final solution for this problem
I don't know what to do!!! The problem is this, very similar to the others mentioned above,: When i conect my xperia sp to fastboot mode, pressing volume up while plugging in usb cable, the phone led turns to blue for few seconds and than it just turns to red showing on the screen the battery image( normal charging mode)...... I' m using windows xp and a rooted xperia sp whit cm11 (for locked bootloader obviously). Just two last things:
the phone can be unlocked( I checked it) and fastboot worked the same as now with stock xperia sp firmware.
Please i need a final and a certain solution for this problem!!!
i'll be very thankful to anyone who give me a hand!!!!

Are you trying to unlock your phone?
Have you installed device specific/fastboot/flashmode drivers via FlashTool? If you are on Windows 8/8.1, you need to disable driver verification to get it done.
Alternatively if you just wanna unlock your bootloader, you can use the BLU option in FlashTool. Again all drivers will need to be properly installed for your phone to be detected correctly.
You say you had the same problem with stock firmware which means you probably haven't setup adb/fastboot properly on your PC. Does your phone get detected correctly in Device Manager? Have you tried installing drivers via Device Manager?
....
So the solution is installing flashtool and installato drivers via Emma?? Thanks forma the attention!!

I meant install drivers via FlashTool. Go to C:\Flashtool\drivers or wherever you have installed Flashtool and run the Flashtool-drivers.exe.
Select flashmode drivers, fastboot drivers and common drivers viskan board (SP drivers) and install them. Like I said if you are on Win 8/8.1, you will have to disable driver signature enforcement. Just look it up in YouTube and follow a tutorial.

Need to flash Ativ S missing drivers?

Hi all.
I started experiencing weird problems with my Ativ S, so I thought I do a hard reset and start clean. I got stuck to a known issue with the Ativ and GDR3, where after hard reset the apps wont instal from the store. The only solution I saw was to flash the device. I have the GDR2 rom so I thought no problem, however I cant get the drivers to instal on the download mode so I could start the flash process.
I have tried to instal 2 different drivers: SamsungUSBDriver.msi and I8750_Qualcomm_USB_composite_driver_HK11-VB717-38.zip Neither of these (that I found, if they are the correct packages) have worked so that the Ativ is recognized correctly in the download mode and I could start flash. When Ativ is connected in the download mode, its only seen as USB DOWNLOADER with exclamation point at device manager.
Im running 64bit Windows 8.1 Pro system.
Any suggestions are welcomed! Thanks!
And installing SamsungUSBDriver.msi results in an error pictured here. Although next time trying to instal the driver is present as it gives an repair option.
Ok so I found this, probably somthing that could be expected: 2. Install Driver on your PC (i had problems with win 8.1 X64, win7 X64 installation fine)
http://forum.xda-developers.com/showthread.php?t=2391138
So I would need a Win7 system, no idea where I would have one... Other suggestions for this?
Ok problem solved by installing Windows 7 to a empty drive just for this flashing. Luckily I didnt have to instal any updates, just the os and the usb driver.

[Q] Unlocking bootloader, stuck at fastboot, problem found

Hi guys,
having exactly the same problem as here:
http://forum.xda-developers.com/desire-500/help/help-rooting-desire-500-t3100840
In short:
1. Trying to unlock bootloader
2. PC and ADB recognize phone withouth problems.
3. As soon as I enter fastboot (manually or per adb command), I get the error:
Unknown USB Device (Device Failed Enumeration)
After trying to get this done over 6 hours, I figured out (as also figured out in that post), that the fault is actually Windows 10.
Microsoft Windows 8.0 and higher (I have Windows 10) use their own USB integrated drivers (drivers for the USB ports).
There is a solution on the internet for this.
Now the problem: I am using Windows 10 32 bit
Those solution are written for a 64 bit Version, so doesnt work with me. (and also not having USB 3.0 ports)
MY QUESTION:
Clearly, Windows 7 solves the problem. I cannot revert to Windows 7 (not my PC).
If I install Windows 7 on a Virtual Machine (on this one with Windows 10), will it use the Windows 7 USB driver or will it use the Windows 10 USB driver?
Thanks.
P.S. Any other solution how to unlock bootloader withouth accessing Fastboot?
PP:S. Just for info, having experience unlocking bootloader, rooting, installing custom-rom, overcloking on phones Huawei Ideos X3 and Sony Xperia E3
Already done
Hi Guys,
in the end I was able to get access to a Windows 7 PC and it worked just fine.
No idea if it actually works also as Windows 7 Virtual PC on a Windows 10.

Can't unlock bootloader, due to can't connect to fastboot

Hi guys,
I want to unlock the bootloader to flash a new recovery image and to flash lineageos on my device.
But connection to fastboot will not be established whatever approach I follow.
Stock Android is updated to the last version through update function.
I followed instruction on lineageos.org and on Sony side for my device to unlock bootloader,
I installed XZ2 device driver,
I used several versions of adb and fastboot (old and new versions)#
I tried Windows 7 prof. 32 bit, 64 bit, Windows 10 64 bit Prof.
I tried USB 2 and USB 3.0 ports
Don't know anymore what I should do to get things done.
If my XZ2 is running in normal Android mode, I'm able to access the internal memory via file explorer as well as
adb devices and
adb reboot bootloader is working.
Result: LED is almost not on, maybe one can detect a little bit of blue color and screen ist black.
Then
fastboot devices or
fastboot print-pit
will not give any answer. :-(
Does anyone have a good idea to proceed before I just give up?
Many thanks in advance
Illo
strange.
had the same issues with Windows 10. had to disable Win10 driver signature enforcement to install the correct Fastboot drivers for the Xz2.
So if it doesn't work in Windows 7 either you seem to have a different problem.
A. Try using different cable
B. Install 15sec adb installer
C. Reinstall the driver again after "adb reboot bootloader"
i had the same issue and tried various method. The thing that did for me was A. Weird, since the working cable was a cheap bundle one..
