[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?

Fastboot with Xperia XP
I have the same problem, can't get it to fastboot mode.
Tried the Windows 8 zith USB 2, and also on XP machine where I was succesfully used it for a Xperia U.

m having same kind of problem i was trying to flash boot img from cm 11 but fast boot isnt recognizing my device any more.my sp is rooted bootloader unlocked.fast boot was recognizing it yesterday.please tell me what to do

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.

[SOLVED] Z3 Compact Bricked after flashing a wrong firmware

Hi guys, I'm currently having problems with my z3c. All happened by accidentally flashing the wrong firmware. After all the wrong flashing now my phone won't turn on nor it will go to "flashmode" using the sidekey method. Only way to get in the phone is by doing "Fastboot" method! Is there anyway i can fix this brick by flashing a stock firmware using fastboot method?
Thanks!

Have you tried holding power, volume up and volume down all together then release all except volume down and connect to the PC (that is ready to flash with flashmode)? Which rom did you try to flash? Normaly you should also be able to enter flashmode.
How do you try to enter flashmode?:
"Power off the Xperia phone and then press and hold Volume Down button while creating the connection between the phone and the computer."
fastboot is only ment for AOSP roms like cyanogenmod other sonys opensource stuff which all require a unlocked bootloader.

Yeah man, i tried everything. Up down and power. I flashed the incorrect firmware for my Z3C, then after the reboot it didn't turn on. it's weird i can't even get into flashmode using the down key and power. Whenever i try the power button it gives 3 vibrates then doesn't turn on at all. Is it fully hard bricked or will i be able to fix this?

Wait, I solved the flashmode. I can access the flashmode now. But theres a problem, I can't flash a firmware using flashtools because my USB-debugging is off and i cannot access my phone to turn it on. Is there anyway i can flash a firmware without usb-debugging? I got all the working adb drivers & etc.... just my debugging is off

Have you tried downgrading/flashing to stock fw 23. 0.A.293 (Device D5803) and then you can root from there.

I can't flash anything, because of USB Debugging off, Flashtool will only allow you to flash if your Debugging is on, and i can't turn on my usb debugging as my phone is bricked.
I need help to find a way to flash the stock firmware!

OK my bad....its just, this tut doesnt say anything about needing usb debugging active on the phone: http://forum.xda-developers.com/xperia-z/general/tutorial-how-to-flash-stock-roms-t2240614 and when I got my Z3C I had to downgrade in order to root and definitely didnt active usb debugging for that.

Cant remember if I have upgraded but my present verison is 0.9.18.5 dated 2015-02-14 which is around the time I got my phone....but can see in the tut they are using 0.9.10.2 if that helps.
And if you look at #5 in tut it says: INFO - Device connected with USB debugging off

0.9.10.2beta6 I've installed that version, i hope it works but doubt it.

I'm trying to flash 23.4.A.0.546 lollipop but with latest flashboot version needs debugging on so I've downloaded and installed 0.9.10.2beta6 but when I try to flash the rom it says "please connect device in flashmode", If I disconnect the phone and then connect it again it will say "device disconnected" and then "device connected in flashmode" but nothing happens... Did you do anything in particular to bypass debugging mode needed problem?

It is possible your device is powered on but the screen is not working (I remember this from the Z1 root procees that required flashing a wrong firmware).
Try to force power down your phone first (press and hold power & volume up for 5 seconds) without the usb cable and reenter flashmode by holding volume down while inserting the usb cable.

Did you install the drivers from flashtool ? For windows 8-10 you have to boot with disable driver verification or something similar. You can find a tutorial here http://forum.xda-developers.com/xpe...rs-windows-t2638680/post50100353#post50100353

[HELP] Unable to flash firmware on Xperia SP C5303 using flashtool

So, the problem is that Xperia SP was working nice on Carbon 4.4.4 but then I flashed a kernel with bad WiFi module. That had a builtin TWRP (I previously had CWM and backed up everything using CWM)... then I did a really bad thing. I renamed boot.img from CWM backup to boot.emmc.win (TWRP compatible) which subsequently flashed CWM and old kernel. I forgot to restore my SYSTEM as some kernel parts are there (I knew it wouldn't work but I had plan to restore it via CWM)
Then I rebooted into recovery but it didn't reboot. Instead it showed me Sony logo and red LED. Then black screen and repeats same. I learnt how to hard reboot and it did no good. I have unlocked bootloader and I'm trying the flashtool but it won't recognize my phone (I have installed C:\Flashtool\drivers\*) on Windows 10 but it didn't do any good either.. Now when I reboot into fastboot mode it shows me blue LED but isn't detected by flashtool;
Same is with the Flash Mode. Green LED but no connection. On the notifs panel on PC It shows that device not recognized. On Device manager it shows: Unknown USB device (Device descriptor request failed)
I wanna install the drivers but they're already done. I reinstalled them twice just for surety's sake... Any suggestions to install drivers and flash the firmware? I don't know much about Sony as this is not mine, this is a free device that no one uses in my family. I own jfltexx
Edit: Whatever mode I put it in it bumps (reboots) out

Try letting the phone in flash mode and wait a bit till windows install driver automatically, or go to device manager and update unknown device driver, if this don't works, i don't know what more to do

Can't enter in flash mode

Hello to all,
I would like to install a custom ROM but unfortunately my phone doesn't want to enter in flash mode! Once switched off, I plug it to my computer while keeping vol down button pressed but instead of entering in flash mode, it displays the battery charging icon.
I hard reset the phone but the problem still remains. Any idea.
Thanks, have a nice day!

My guess is either the USB cable (did you use the OEM cable?) or the drivers (does windows recognize your phone?). Removing the SD card or first entering recovery were suggested earlier (http://forum.xda-developers.com/xperia-l/help/update-volume-connect-doesnt-t2613733). But more experiences Z3c owners may have better ideas...

Using flashtool:
Turn phone off completely.
Start flashtool, choose flashmode and choose which firmware you are going to use. Tick Exclude TA.. Click on flash.
It will start preparing the build and after a few seconds it will ask you to connect the phone.
Plug the phone in while holding volume down, as soon as flashtool starts doing something, you can let go.
If you don't know how to use flashtool then I urge caution, Sony's aren't like flashing a Samsung, it is actually possible to brick your phone with flashtool. There are lots of questions on 'how do I fix my phone?' in this Q&A thread from people who didn't read up on what they were doing.
Recommend you read bilboa1's great guide on what to do, starting with backing up your TA partition..

Thanks for your answers but I think the mini usb from my phone must be dead.
About Flashtool, I can't use it because I can't go into Flash mode! Moreover, my phone is not recognized by windows. I tried with several usb cables and computers when I plug it, I don't have any MTP or PTP choice, it can only charge..
On Windows 10, devices is not recognized and Window 7 see it as a 5880!
And I tried to remove SD and SIM cards..

If the USB lead was dead you wouldn't get the charging icon on your phone.
Have you installed the Sony drivers.
You also need to run exe in the Drivers folder within Flashtool, to make sure you have correct flashomde drivers available. Installing these drivers is very difficult in Windows 10 and it require restarting the machine in safe mode, and going into the advanced settings to disable driver signature checking, this how to video is for windows 8, but you'll get the idea
Have you installed ADB?
Sonys PC Companion should set you up with the correct connection to your PC

Have you tried other USB cables?

Yes, I've installed PC Companion, adb drivers but nothing appears when I use command "adb devices". I've also installed flashtools drivers but deactivating drivers signatures in Windows. But when I try to flash, flashtool ask me to turn my device in flash mode (switch off then volume down + power) but I can't do that.
I've tried several usb cables. Some are charging my devices, some are aren't but none of them allows me to data transfer!
I've also tried to force MTP or PTP usb transfer in developper option, it doesn't work more..

Do you have any warranty on your phone, you could be right that the usb socket is damaged somehow, but it's strange that you can still get a charge through it.
Your only chance at moving to a custom rom change is flashfire
This should let you flash a rom without recovery.
Edit: Flashmode is just holding down just - volume button, not volume+power
Obviously your chances of rescuing a failed install are going to almost zero without recovery and flashtool, so be very very careful about what you try and flash in flashfire. Read up completely that the rom you want to flash is going to work pushed on top of whatever you are running at the moment.

For anyone who might be interested, sometimes you have to try a USB 2.0 port or just a different port. I had the same problem while using a usb 3 port, switched to 2.0 worked like a charm.

Try to open the back of the phone and removing/unplugging the battery wait 5 seconds and then put it in again. Then try holding down the volume down button while you connect a usb cable.

I don't think so because this happened to me long ago when I tried to unlock bootloader.But I did something to the driver to work adb properly and it worked.And now I forgot that method and couldn't find in google also.So I'm really in big trouble.I just don't know why when I want to flash the stock rom and flashtool show in popup to power off the phone and press vol down button and connect to computer using usb cable but vol button don't work or not give any signal to computer.So I can't flash the rom.

Go to sony official site and download drivers.. ZR drivers dont exist but you can use drivers for Z, install those on your computer and use the fastboot method again and you should be fine.. Your phone is only soft bricked.. Hard brick is when there are absolutely no life in the phone at all.. Use a boot.img you know will work and no need to flash stock ROM once you're in recovery.. Unless you want to of course.. Custom ROM will boot your phone just fine
Also take your battery out and re-insert to make sure your phone is properly off.. Flashtool should also work after that

I don't think so because this happened to me long ago when I tried to unlock bootloader.But I did something to the driver to work adb properly and it worked.And now I forgot that method and couldn't find in google also.So I'm really in big trouble.I just don't know why when I want to flash the stock rom and flashtool show in popup to power off the phone and press vol down button and connect to computer using usb cable but vol button don't work or not give any signal to computer.So I can't flash the rom.

Go to sony official site and download drivers.. ZR drivers dont exist but you can use drivers for Z, install those on your computer and use the fastboot method again and you should be fine.. Your phone is only soft bricked.. Hard brick is when there are absolutely no life in the phone at all.. Use a boot.img you know will work and no need to flash stock ROM once you're in recovery.. Unless you want to of course.. Custom ROM will boot your phone just fine

ZR driver exist in Sony developer website and I installed the driver but I don't know why my computer not recognizing my phone.My phone can turn into fastboot mode(blue light on when pressing vol up and connecting cable to pc) but when I type command "adb devices" the listed device is empty I mean no adb fastboot device found.I'm just asking the drivers are not working beacuse of windos 10?Actually when after I use custom rom I couldn't connect my phone to pc.So any driver can fix this problem?I searched really hard on google but couldn't find any proper sloutions.

This isn't helping!

Windows 10 is a pain to install drivers into.. But use fastboot in flashtool instead of flasmode.. Should recognize your phone and flash the boot image from there

I know you are trying to help me but I tried everything and nothing is working.I installed driver from flashtool but still no clue why pc not recognizing my phone.My phone is like a live junk.My phone soft bricked many times and I could recover my phone with flashtool so I know what to do but this problem is way more confusing.I just need to know what is causing this issue.

You've managed to install the drivers inc the lagan drivers in flashtool and connected your phone in fastboot mode with flashtool running and flashtool still don't recognize your phone? I've done that loads of times even with no drivers installed and flashtool has been able to recognize the device in fastboot.. If that's the case, then I'm sorry I'm not able to help any further as flashtool has always been my failsafe when things have gone wrong.. Adb and fastboot are usually no help for me in Windows 10..

Flashtool is the best tool to recover soft bricked phone I know but this problem is way more complicated.
Thanks that you tried to help me.I hope I'll figure it out some time later.

My problem was created because local charger damaged my phone battery.So I couldn't turn on my device like yours.I replaced the battery and charger from Sony Center and now my phone is good as new.So Try to use other good battery(small or similer size that suites to your phone's battery pin)and see if your phone turns on without any issue.Then you can target the problem.
