Ive been trying to get fastboot to work on my phone for weeks, no methods on this site have worked. Ive tried another pc with windows 7 and its the same story. I have rooted my phone but I kept the bootloader locked. Is an unlocked bootloader an necessity for fastboot or am I missing something?

you must have the fastboot and flashmode drivers installed on your pc ,and the xperia s drivers also.....
you enter fastboot when you turn off your phone and you have to press volume up while you connect your usb to pc and you see a blue led .....
i assume fastboot is working before you unlock your bootloader as you unlock the bootloader using fastboot...
what do you want fastboot?

I want fastboot to install custom roms on my device. I could use a hand getting the drivers to work.
My system is windows 8 which is know there is issues with but i have tried:
Plugging phone in while holding volume button.
Lights comes on green and windows sees the device.
Right click and click update.
Select the drivers and select bootloader interface
plug the phone back in and click next
Then the update fails.
Any thoughts?
You need to disable driver signature verification. Do an advanced restart from windows 8, from there there is an option to disable it. After that you should be able to install the drivers fine.

You can not unlock the bootloader without fastboot.
Some phones can access fastboot some are locked out. Chances are, if you paid a discount price through your carrier, your phone has fastboot blocked. If you bought the unlocked full price version you should have access.
You can check if the phone can access fastboot. With the phone off, press volume up and plug into a charger/pc. Do you get the blue led on phone? If no blue led then pc drivers won't help.

Thanks for your help, the light is green so im guessing I dont have fastboot. Is there any other ways I can install custom roms to my phone? Or un block fastboot?
Sent from my LT26i using xda app-developers app
I have the same problem! im so sad, im going to seel this one and buy an unlocked one.
If you are with windows 8 connect your phone by an usb 2.0 port. This solve your problem. Fastboot, flash mode and software like Emma, flashtool doesn't support usb 3.0 with windows 8.
Best regards
Look the end of that post

Make sure your pressing the volume up button to enter fastboot mode, blue led. If you press the down button you should get the green led for flash mode. They are different modes. Flash mode is for .ftf files. Fastboot is for .sin files.
From the dialer enter *#*#service#*#* or *#*#7378423#*#* then click on configuration. This will tell you if you can unlock or not.

I do t use usb 3.0 with my phone. All I want to know at this point is since my phone is with o2 and my bootloader is locked has fastboot also been locked? My phone is rooted, there must be a way to unblock fastboot if that is the case

Then no fastboot. My AT&T branded Ion is this way. When I do the service code in previous post, configuration shows bootloader unlockable NO. Means no official unlock, no unofficial way yet to unlock at all

I was trying to installing arcknight kernel..
And by doing this you have to go fastboot which i believe is turning off ur phone and plug the usb while holding the back key after that u have to type fastboot flash boot (name of kernel.img) and it says waiting for device.. ive been waiting for like 10 minutes nd nothings happening..my phone remains black but the led is green..sometimes changing to blue then back to green..
Am i forgetting something or skipped a process?
Sent from my LT18i using XDA Premium App
no,if you do that using flashtool you have not to hold the back key.after your phone is connected being recognized by flashtool you have to chose fastboot mode then reboot in fastboot mode(via ADB) that willsend your phone in to fastboot mode then you can select a kernel to flash it!
Fastboot is hold options button and led goes blue.
If Ied is green your are in flash mode.

Yah.. when i connect the phone its green..so im in the flash mode.. but how to go in fastboot? I followed the steps correctly but still in green..
So by the fastboot i will hold the OPTION KEY instead of back key while connecting the usb?
Can u teach me the exact instructions and its every detail?
DO i need my bootloader to be unlocked?
Sent from my LT18i using XDA Premium App
first of all is your bootloader unlocked or not custon kernels cannot be installed on locked bootloaders.
so if its unlocked press menu key and and attach cable to enter fast boot mode and then u can flash custom kernel by cmd line method or flashtool ( more convenient IMHO) .
for archnight kernel after u flash kernel u need to flash WiFi modules in CWM.

You have to put W8 in testmode to be able to install all proper drivers
You can Google how to do it, it's easy then just install the drivers from flashtool/driver folder

I had the same problem with my cousin's pc, and a friend is also having it. I think you should force the reinstall of all drivers (if you're on Win 8, don't forget to disable signature driver check)

Hi, i have an xperia play r800i and i recently unlocked bootloader, installed CM, and then had to reinstall stock firmware and relock bootloader. Now, i have unlocked my bootloader to reinstall CM (I know it seems silly) but flashtools says i'm connected in flash mode no matter what button i've held during connection and i've tried every button on it and each one connects in flash mode.
Thanks for any help

To install fastboot drivers you have to be very fast, 2 or 3 times practice is necessary. Going to device manger install your driver so quickly then you can get your phone at fastboot mode easily. You won't get time more than 3 to 4 seconds.....!
I think, you already have fastboot drives downloaded at your PC, thanks!
If the problem again remains, please update your flashtool...! This also may be an issue.

Use this kernel http://forum.xda-developers.com/showthread.php?p=42005739
This is advanced stock kernel which has pre-loaded CWM recovery, when phone reboots you will get led to yellow then press volume + & you can use working recovery!
And then flash latest 6.2.B.1.96 FW..!
But if u want rooted 1.96, don't forget to follow this tutorial...!

Flash a ftf and start over, and confirm you've actually unlocked your BL. You clearly haven't read instructions properly either, so do that, rushing when you don't know what you're doing makes things worse.

Great!
As for your fastboot problem: After you installed flashtool, did you go into it's folder, then to the "drivers" folder, and install the fastboot driver from there? (it shows you a list of drivers available for install - I believe fastboot is near the bottom?) Note that if you're going to do this on Windows 8, you will need to disable Driver Signature Enforcement

Try flashing a kernel, make sure the Phone is connected to the computer and in fastboot mode before running any commands, reboot both if it still fails and/or try another USB port.

I'm with @XperienceD on this - it's time to pause and do some more reading and research.
That custom kernel you just flashed - what firmware is it based on? It's a good idea to make sure that kernel is compatible with the base system firmware that is currently on your phone.
