C5306 Fastboot - doesn't work - Xperia SP Q&A, Help & Troubleshooting

I have a Xperia SP model C5306 on Fido in Canada that I cannot for the life of me get into fastboot mode. The phone is carrier unlocked (by unlockthatphone) and I've verified it on another carrier. I have also rooted the phone with the doomlord exploit successfully.
When I hold the volume up button and plug the device into my Win 7 Pro 64 bit PC the LED goes red for a second then orange once the battery charging icon appears.
The phone seems to have no problem getting into flash mode but fastboot is a no-go.

To get into fastboot you need an UNLOCKED bootloader, it is not the same thing as a SIM unlocked phone.

Based on all of the instructions I've read fastboot is required in order TO UNLOCK the bootloader, including those from Sony. If you can't fastboot until the bootloader is unlocked how do you unlock the bootloader?

Have you a SIMLOCK? Have you became that phone from your provider?? it can be that the provider disabl the fastboot that you not can disabl the Simlock

I bought the phone from a provider but I have carrier unlocked the device through an unlock code that I bought from Unlockthatphone.com
Is that different from a Simlock?

Have you installed the drivers yet?
This phone is quite funny, it restarts after a few seconds of inactivity in Fastboot/Flash mode
Catching my breath, letting it go, turning my cheek for the sake of the show

I have the drivers on my PC, I downloaded the ones from Sony and replaced them in the SDK folder. I haven't got to the point where my computer asks me to install the drivers. I'll try this.

649 34535926
So when I hold down the volume up button and connect my phone to the PC via USB I see a green LED (fully charged) on the device and my device manager tells me that there is a Sony Ericsson seehcri Control Device connected. If I navigate to the Driver information of that device the driver is pointing at the Windows System 32\drivers\seehcri.sys driver.
When I try to update that driver to the Fastboot driver it says there are no 64-bit compatible drivers in that folder. Are there 64-bit drivers for fastboot?

Okay, Sony's fastboot drivers are not signed, so to install the drivers, you need to disable driver signature enforcement in Windows first.
Look here for more info: http://forum.xda-developers.com/showthread.php?t=2354721

Try this method.
Install Drivers
Fastboot Mode - Blue Light - Turn phone off>Press and Hold Volume UP button while plugging in USB Cable> Release the button (from being held) after the blue light.
Flash Mode - Green Light - Turn phone off> Press and Hold Volume DOWN button while plugging in USB Cable> Release the button (from being held) after the green light.
Common problem is it doesn't stay too long on specific mode
You will need drivers try downloading Xperia Z driver here - http://developer.sonymobile.com/downloads/drivers/xperia-z-driver/
(Optional in case you can't Install the driver correctly)
Install Driver first
1.Extract the downloaded file. (If it is in Zip file) in a place where you can easily locate it.
2.Connect your phone (turned on) to your computer
3. Assuming that you have My Computer Icon on your desktop.. Right Click it > Manage> Device Manager (Located at the left tab) > Android Phone> android ADB interface > Right click> Update Driver Software > Browse my computer for the driver software and locate where you put the XZ driver.
4.Done!.
It worked for me, hope it will work for you, too.
Guys, you can correct me if I am wrong..

My major problem is that i never get a blue light when I hold down the volume up and plug it in. My computer makes that sound like a uSB device had been unplugged in a couple seconds.
Also, I download the drivers, and with the device powered on, plug it into the PC. What I see in the Device manager is Sony sa0108 ADB Interface Driver. If I disable adb on the device I get nothing in the device manager.
Flashtool will not allow me to do the adb fastboot reboot either.
This is extremely frustrating!

[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.

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.

[Q] Flash Mode Not Working

I recently flashed DooMKernel for my Xperia SP via fastboot. After that, I flashed the kernel (only kernel) of the stock 12.0.A.2.254 via flashmode. However, after that, both fastboot and flashmode are not working on my device. When I hold either the volume up/down button when I plug my phone into my computer, the notification light turns blue/green for a while before turning red for a while and booting normally. I have already installed the fastboot and flashmode drivers successfully and I recently upgraded to Windows 8.1 x64. What can I do to fix this?

The funny thing is that it actually does turn blue/green. That goes to show that it's working, it's just that after a certain time of being in that mode, if there are no detectable data transfers, it will restart.
Also, have you disabled driver signature verification and test signing on Windows 8?
This message was sent so that I'm slightly more useful
As CallMeVentus said it works but then reboots. If you're using flashtool you can first select the firmware to flash and when you start it will ask for you to plug your phone in flashmode. Do it and it should directly copy the files, so your phone will stay in the right mode.

CallMeVentus, I have already disabled driver signature enforcement in Windows 8.1 and have reinstalled the flashtool drivers three to four times already. When I plug the phone in fastboot or flashmode, Windows tells me "USB device not recognized". However, when I plug it in as MTP, it detects the device normally. I have used many different USB cables and the problem still persists. Does it have anything to do with my recent upgrade to Windows 8.1?

[Q] Fastboot

Hey, I had been trying to unlock the boot loader but when i´m in fastboot mode it only stays for seconds in that mode, what can I do?
Same here. My solution:
Download the drivers from the pack in this post. http://forum.xda-developers.com/showthread.php?t=2090268
Open the device manager before connect the phone to the usb cable.
Follow the procedure: press volume up and connect.
Right click on the device manager when "S1fastboot" appears.
Select update driver.
Select the folder where the drivers from first step are.
If the led goes off and you can't install the driver, go back at the beginning of the update driver window, and unplug and replug the phone. If you act with good timing, you get the driver installed.

Recovering from bad bootloader flash

I have an XZ1C that I seemed to have damaged the bootloader during a flashing operation.
I have a working OS and can reboot the device with adb without problems via an "adb reboot bootloader" call.
When the device comes back, I'm unable to install the device drivers since the USB IDs are different than are supported from the regular XZ1C driver. My device is reporting as VID 0FCE PID 0DDE. This still seems like an Xperia IDE, but the ID is not supported from the regular Xperia driver.
Does anyone have any ideas how I can reflash the proper bootloader, or have pointers to a specific driver that might work given the odd mode that I've managed to mangle my XZ1C into?
Much thanks!
I didn't understand, what you mean with I can reboot the device via adb....
From my personal view : if the bootloader is broken, no connection via adb could be possible, no fastboot is possible and so on....
Maybe I'm wrong?
If the device is available, is the USB debugging in the Dev menu and OEM unlock enabled? Could you accept the fingerprint?
The VID/PID combo of 0FCE:0DDE is the fastboot device identifier.
If you're trying to get to flash mode, the procedure is to:
- Disconnect the phone from USB.
- Power off the phone.
- Hold the Vol-Down button.
- While holding Vol-Down, connect the phone to your computer via USB.
This will activate flash mode with a VID/PID of 0FCE:B00B.
You can tell the difference between the two by the color of the notification LED.
Fastboot mode has a blue notification LED, while the flash mode color is green.
Not sure I understand fully what you mean but if you're running windows, change the driver manually to Android ADB device once it's plugged in. Windows should recognize fastboot mode at that point you can flash a new boot image.

XZ2 compact - no fastboot mode

Hi,
I wanted to install Lineage OS on my Sony Xperia XZ2 compact. It has the latest stock firmware installed.
adb devices lists my device, preconditions are ok (bootloader unlock yes and debugging enabled and authorized)
adb reboot bootloader: the phone turns off, red light for 3 seconds, vibration, cyan light and black screen
fastboot devices simply does nothing
turn phone on again
turn off phone
hold volume down + power on -> vibration, "SONY" appears, "SONY" disappears, vibration, phone boot into normal work mode
I do not get into fastboot mode
Any ideas?
Best regards,
Ghost

Can you try
Code:
fastboot getvar all
If your device is recognized correctly it should either give you a long list of values or an error.
Else you get something like "Waiting for devices".

nothing else

Okay. Then it makes sense that "fastboot devices" shows nothing.
Your problem is that your computer doesn't detect your phone in fastboot mode.
I think your cable should be okay (since adb works) but maybe you need some additional drivers?
You can also try solutions you find in the web if you search something like this:
Computer doesn't detect phone in fastboot

Or "Windows" instead of "Computer" if you use windows etc.

Ok, I got it. I did not turn "driver signature enforcement" off on my Win 10 system (but I got no error during driver install). After switching off "driver signature enforcement" and re-installed the adb and fastboot drivers, I got a warning that a driver without signature will be installed. I confirmed that warning and now fastboot is working well.
Hello, hopefully someone can help me.
I have the same problem as mentioned above. I also tried to deactivate driver signature and install new but it didn't work. Maybe I did it wrong.
I used this command and rebooted with deactivated driver signature.
shutdown.exe /r /o /f /t 00
I also tried to install specific adb drivers for xperia xz2c manually instead of universal adb drivers.
Any more ideas?
Thanks and regards
I'm facing the same problem. I've installed multiple adb drivers, with and without driver signature enforcement, and nothing works.
adb works fine, and device is listed, but as soon as I do an adb reboot bootloader, the device is gone. Also, for some reason, I do not see any cyan blue LED lighting up in my unit (the LED itself does work though).
Was able to fix it. The trick is to start the phone into fastboot (vol down+power), and then go to Device Manager and install the drivers from Sony on the recognized device.

Hi, a.bispo, do you have any link for these driver because I have tried several on sony website and none work for me.
Thank you,
I got them from Sony's website as well.
The trick was putting the phone into fastboot, letting Windows recognize it, and then manually install those drivers' files.
Just an update from my experience: I had to go into device manager and select an alternative driver for the Android! device that popped up. Not sure if this is mandatory or not but I did this after the fastboot devices step where my device isn't detected.
