[Q] Unable to access Fastboot mode

I read through many threads and have followed the official Sony bootloader unlocking instructions. I have requested and received the unlock code from Sony via email. I have downloaded the inf file and placed it in the correct folder in Android SDK (which I also updated). But I am cannot access fastboot mode, I hold down Vol + and plug in the USB cable but the device shows a red led and goes into charging mode. Also the PC never prompts me to install fastboot driver it simply loads the SP as Sony mass storage device (in device manager).
I have read that some people seem to think that the SIM lock affects the ability to access fastboot but this SP is SIM unlocked. Sony's official guide to unlocking the bootloader says I need to access fastboot mode to enter the unlock code but how can I unlock the bootloader if I can't get into fastboot mode?

hmmm... don't know really... i once entered fastboot mode by mistake, while trying to root stock rom. wasn't reading instructions and put device in a fsatboot mode instead of debugging... was on stock rom so don't know if custom rom would let me do that. should check myself... if anything i know it is possible to get me that blue light shining.

To enter fastboot mode in Xperia SP just power down the phone and hold down the volume up key while pluging your phone into your pc
If you need flashmode do the same thing but with the volume DOWN button held down.

I´ve got the same problem. I can´t enter in flashmode neither in fastboot mode. I´m on windows 8 32bits and I installed the .245 Deodexed ROM with a problem on root and without CWM. I don´t know what to do now, please help me.

As I explained in the first post, I understand how to access fastboot mode (and flash mode). I got root and backed up the TA partition, the stock apps (from 1.257) and backed up the stock ROM. Then, after I wasn't able to get into fastboot, I have installed CWM for LB and flashed a custom ROM based on 2.245. I am able to enter flash mode but not fastboot. As I said before, the phone is SIM unlocked but is acting like it came from a carrier, with locked bootloader and fastboot disabled. How can Sony disable fastboot? I don't get it. Any one want to take a guess how long I will have to wait until some clever dev finds an exploit?

Sorry for that i dont think that it is your computers fault because you enter fastboot (and flashmode) using your mobile phone NOT your PC
So i would roughly assume that this is a Rom bug or something in the flashing proccess went wrong.

Thanks for trying to help, but I understand that flashmode and fastboot are accessed using the phone. Actually the phone needs a piece of software like flashtool to keep it in flashmode otherwise it drops into charging mode. I didn't mention my computer so I don't know where you got that from.
As I explained, I am unable to access fastboot with stock ROM (1.257) and a custom ROM (based on 2.245) so it can't be a ROM bug or the flashing process having gone wrong.

if it's not too much of a trouble for you, go and flash .245 stock, than .257 stock kernel only. like you are trying to root it for the first time, complete rooting procedure, and than proceed on to installing CWM, but instead of connecting device in debugging mode to install CWM, try and see if you can put it in a fastboot. this was exactly the moment when i accidentally put mine SP in fastboot. of course, i'm not saying to go ahead and install anything if you score, but only to confirm if you can put your device into a fastboot mode since installing anything without CWM will likely soft brick your device.

Same problem here, i can't do anything using flashtool after flashed 2.245. I did with SUS, maybe is some flashtool issue.

It may be a flashtool problem you are right because 2 incidents with different Roms that both use flashtool to flash those roms.....
its pretty much self explenatory.

Interesting. Ok, I've read up on the process. So I use the various stock .ftf files and flashtool with the phone in flash mode? Bear in mind that kernel didn't allow fastboot when I used it with the stock .257 ROM the device came with. If I do it, I will nandroid backup first, of course, but I think I remember reading in one thread that someone managed to soft brick their XSP doing this very thing.

Bear in mind that kernel didn't allow fastboot when I used it with the stock .257 ROM the device came with. [/QUOTE said:
that's why you need to complete rooting procedure. root stock 1.257 kernel, than back to stock 2.245 with root preserved, and before you would install CWM try to put device in a fastboot mode, this assuming you still have a UB.

have you tried to boot into android, open a root terminal and type
exec reboot bootloader
that should bring you straight into fastboot

All that happens is that the terminal session ends and closes (not FC) the terminal app. Using the same command via adb just does a standard reboot.

i just placed my in a fastboot mode, no problems whatsoever. do you have drivers for the device installed? you will find these in flashtool installation folder.

Yes. The fastboot_with_android_usb_file.rar package specified on DooMLoRD's bootloader unlocking/relocking appears to have been removed and there are no new links in that thread. So, I found and installed the drivers included with the flashtool. But it seems to be the device that is the problem. It is acting like a carrier locked model. I am rapidly starting to believe that this one has a locked bootloader.

I said before, it's new firmware (maybe RU) with a Windows Flashtool issue. Today i did flash kernel to my SP using Linux client.

Hi, I have some similar issues. I've also been flashing some stuff and whenever I try to go to fastboot it just boots into CWM. Very annoying to say the least. The dark blue light goes on when i hold down volume up and for a short moment I see the fastboot driver installing on my computer. But before it completes it's already in CWM.
Not sure what to do from here on wards, maybe some advice on which kernel to flash? I am pretty sure the latest kernel I flashed is the .254 root kernel from doomlord.
Ps. I really would like to flash CM when it becomes available as nightly :angel:
Thanks in advance!

I had already installed cm10.1 jb for my xperia ion.
Now i tried to install cm11 kitkat for my xperia ion.
Every thing is gone good.
But now got stuck up with a problem.
fast boot mode is active only for 5 seconds while connecting my xperia ion to System with flash tool.
help me to do the need ful.
Guide me to download compatible drivers and flash tool for fast booting process.

If you have UNLOCKABLE bootloader, then you dont have a FASTBOOT mode on your phone. Its just pure luck. some phones dont have it... kind of a sony crap... I also happen to be one of those LUCKY ppl. no unlock, so stuck with Stock kernel forever.
When you connect your phone to Flashtools in FLASHMODE...
See for a string BOOTLOADER: NOT_ROOTABLE.... it means you belong in the lucky group...
If it says rootable, then you're doing something wrong.
Pardon me if i read something incorrect. i skimmed through all the posts before posting.

Help me unbrick my Xperia T...

Hey guys,
seams like there went something wrong when trying to install latest cynagen Mod to my Xperia T - Now it is blak screen, is not recognized by flashtools or fastboot (so i cannot flash anything else). The LED is also not doing anything at all. The only thing that "works" is if i keep the power button pressed longer for 10 sec, my phone vibrates and shows the Sony logo - nothing else.
What i did: I opened the bootloader (which seemed to work, bootet the device afterwards and everything was ok), then i followed this instruction to install cynagen mod: wiki.cyanogenmod.org/w/Install_CM_for_mint
After Step 5 (Open a terminal on the PC and enter the following:
fastboot -i 0xfce flash boot boot.img
fastboot -i 0xfce reboot
While the device reboots, press the Volume rockers a few times to load recovery. )
the phone was dead. So i think there was something wrong with flashing the boot.img, but i see no way how to "undo" this, becuase of no tool will see my phone on the pc...
I really appreciate any help! Thanks, Simon

Maybe your battery is dead. Keep the power button pressed with a rubber band while it charges (wall charger) for a few hours. Then try to put it in fastboot mode and flash a kernel/boot.img with Flashtools, which is a lot simpler and less prone to typo errors than doing it yourself in a terminal/command line.
Also, you might rather look up tutorials here in XDA instead of on the CM site; they generally tend to be a lot easier to understand and even more practical.

If the phone displays the Sony logo then there's nothing wrong with the battery probably.
Use Flashtool to install a stock FTF is the first thing to do. CM requires an unlocked bootloader, I'm assuming you have a locked bootloader.

Last CM kernels are buggy.
Try with an older kernel, that you can pick from here (our device is MINT): http://fxpblog.co/cyanogenmod/cyanogenmod-11/

Xperia V won't go into recovery

Hey there. I'm having a bit of an issue regarding the recovery on my phone. I rooted it quite some time ago but now I'd like to upgrade it to Kitkat 4.4.4 but when I try to enter recovery mode, it just boots normally. I have installed ROM Manager some time ago and I believe I may have changed my recovery, but it was either CWM or TWRP so there's nothing else. I tried using the "Boot into recovery" option but the phone won't go into recovery. I tried many different combinations upon boot but none have worked. Can someone help me, I'm running 4.3 9.2.A.1.210. I have USB Debugging enabled.
Cheers.

Most (or even all) of the custom roms have built-in recovery. So, if you want to flash some custom rom, you extract the "boot.img" from the zip and flash it via FlashTool using fastboot mode (to put Xperia V into fastboot mode hold volume up button while connecting the phone to tbe pc and the led should turn blue. If it turns green then try holding the other volume button.). And then you just select the lightning icon in FlashTool, choose fastboot mode, on the right side in the middle is an option to flash kernel and just find the boot.img you extracted and select it. Keep in mind that your bootloader must be UNLOCKED and you must install fastboot drivers before doing this.
Btw...your phone will stay in the fastboot mode only for a couple of seconds so you have to be quick...I always find the boot.img first, then put my phone into fastboot mode and then just select the image to flash it.

xperia Z3c bootloop after flashing CWM

I recently got a z3c and decided to try to get a slim rom on it.
I have done the following:
I unlocked the bootloader.
This was done successfully to the best of my knowledge
The next thing I did was flash a cwm image to by z3c using fastboot. The problem was that I flashed the z3 version on my z3c.
The device would boot but the screen would be blank.
Later I flashed the z3c boot loader named : Z3c_DooMLoRD_AdvStkKernel_v01_FW-105
After this the device goes in a boot loop. I am able to access CWM.
I have tried to root the phone as well as flash the slim rom in an attempt to fix it....
Wiping disk / cache doesn't help.
Also for some reason even though adb drivers are installed I cannot use it so I can't get the twrp install to work.
I have no idea what to do can someone please help?
Thanks,
stp

I have same issue....Phone is ib bootloop...i can still go to fastboot mode....
Anything can be done here????

Flash an factory image with flashtool then you will have original recovery. Then reinstall CWM, maybe smth went wrong.

Tried flashtool---Ended up with errors as attached pic
As i cant bootup my phone...USB Debugging option cant be ticked
I was running SlimLP (unofficial) while bricked my phone....
Anything on that please....

I managed to recover my phone. I don't think you need usb debugging for flash tool. What I did was turn the phone off (power and volume up seem to be the buttons that force shutdown and break the reboot loop).
flashtool will prompt you to connect when you flash the ftf file and you hold power up and volume down when you connect the usb cable. If you have issues flashing (it hanged on me on system.bin) try restarting your computer.

Resolution and Problem Exp
Right after flashing the device recovery through fastboot the USB cable is plugged and that seems to loop the boot loader, so you need to force shutdown while looping by pressing POWER + VOLUME UP, and after that unplug the USB cable. You will notice that on boot now the light is no longer red.

Final Solution ROM bricked(?) my phone?

Hi,
I just installed this rom:
http://forum.xda-developers.com/xperia-sp/development/final-solution-rom-lbl-t3073678
Everything went fine. I did all the steps. After installing the ROM and the fixes I chose system reboot from CWM Recovery. Since then I can't turn my phone on. If I press the power button there is a short vibration, but nothing happens.
1. Tried to reset with the button on the back of the phone. No go.
2. Tried all the button combination but can't even get back to recovery.
3. If I connect it to my computer then the led goes green and windows gives me that sound when you connect something new, but after 10 seconds the led turns off and I get the other sound for dismounting device. No diver can see it, neither flashtool does.
4. It doesn't charge. Well, at least the led does not turn on so I guess it's not charging.
Any idea?

You have a kernel problem, Flash with Flashtool the kernel of your rom in fastboot mode (Volume +, and connect your usb cable) with flashtool or if that don't available, flash a stock kernel in fastboot mode (Volume + and connect your usb cable at your phone), when it's flashed, restart your phone

Normally, you can flash the kernel included in your rom, it's a file name boot.img, flashtool is good i think, can you send error messages with flashtool if you have any messages

I double checked that it works for locked bootloaded. It's even the name of the thread: [Final Solution ROM][UBL/LBL][V2][ODEXED for extreme smoothness][William's Kernel]
So the issue now is that I can't even install the driver (windows 10) as the device is being disconnected after 10 seconds of plugging in. I got the tft file now for the stock kernel and installed flashtool but it can't detect the phone (in that 10 secs), it says that driver is missing. Tried the C:\Flashtool\drivers\Flashtool-drivers.exe and selected the necessary drivers but it never succeeds. Attached the screenshot of the failure of installing the drivers.

Yeah i know that your bootloader is not unlockable, by ftf loading i mean that select .ftf you want to flash first and wait until it prepares and prompts you to connect the phone, btw last flashtool that works with sp is flashtool-0.9.18.6 , if you will have problem with understanding that try to search how to flash ftf on xperia sp on youtube i hope you will get it eventually
towelroot is an app from geohot you can get it here https://towelroot.com/ it can root your device
super su is an app on google play it is free and it controls root apps, in other words it grants or denies root access, once you will gain root with towelroot, open super su and it will prompt you to update binary just select normal and it will work

you cant use fastboot with your bootloader locked that is the point there is NO WAY of flashing custom kernel with bootloader locked or you will brick your device, only way to flash kernel on lbl is to flash stock kernel in your case WITH FLASHTOOL TROUGH FLASHMODE

I understand what you are saying. But flashtool doesn't let me flash kernel in flash mode.
So it's a catch 22? After all this means that it's already bricked, isn't it?

You are not trying to flash kernel only, but that is possible too, you are trying to flash whole stock firmware.
Yes your phone is bricked because you flashed custom kernel on LBL.
Download some .205 or .207 firmware from android development section of xperia sp xda forum and flash it with flashtool.
There are plenty of tutorials online, i dont mean to be rude but you just must try and understand it yourself.

Wait a sec. It seems I could flash the kernel in flash mode.
It was keep disconnecting but finally the sony logo appeared and it booted to the system. It doesn't work properly, and it's very slow, but now I can get into CWM. Do you have any suggestion which ROM should I install on it?
