[Q] Xperia P {Fastboot Issue on Branded Handset} - Sony Xperia P, U, Sola, Go

Hi Guys. I own a Branded (O2) Xperia P on stock 6.1.B.0.5.44 ICS.
I am trying to access fastboot so I am able to install a unbranded stock rom on my Stock Handset.
To do this; i know i have to access fastboot however i am unable to do so. I have tried every method possible however my handset still goes into charging mode (Hold Volume down then insert usb, Volume up then insert usb, Both volume keys then insert USB)
Just to let you lot know I have read through every thread related to users not being able to access Fastboot however I still haven't found a solution on how to Access It. I have tried manually installing the fastboot drivers however I still wasen't able to access fastboot.

to use fastboot to flash a new kernel you need to have a unlocked bootloader

follow the instructions on this site to see if you can

[Q] Neo v Can´t enter in fastboot mode

Hello everybody!
Recently bought a xperia Neo V and would like to install custom roms on it and kernels,
however I can not put the device in fastboot mode mode to flash the kernel.
Have rooted the device, installed the CWM and the unlocked bootloader by testpoint method.
According researched, to enter the fastboot mode should hold the menu button and insert the USB cable
but when I do that the phone turns on a red light and charging symbol appears. the device goes into flash mode (green LED) and has usually managed to install custom roms but not kernel.
My phone is SIM unlocked.
I appreciate all the help available ...
Sorry for my poor english...

If your phone is sim locked you cannot enter in fastboot because it is also locked.
You have to unlock the phone (search for SE Tool or Omnius) and then you'll be able to enter into fastboot mode.

Type *#*#7378423#*#* if rooting status =yes then you should have fastboot, power off the phone hold menu and connect to pc led should be blue, if not try reinstalling the drivers. Tbh flashtool handles fastboot too, I don't know why less experienced people don't just use that, you can't make a mistake with the commands and it solves the driver issues.,

There are many threads that walk you through setting up fastboot, or if you in a hurry or too lazy to search use the fastboot toolbox included in flashtool.

Neo V Not entering into FastBoot
HI,
I have Sony Ericsson xperia Neo (MT11i 11W41). Couple of days before I received online update. I accepted, and downloading and installation started.
After that my mobile gone sleep mode. NO LCD Display not charging indication. Green led flashes on mobile charging, and orange 3 flashes on Power up.
I spent lot of time on net but could not find solution to power up my mobile. I did many firmware through flash tool, Zero point and S1 Tool But no solution.
Even I tried Emma, it displayed all information and shows “Phone is locked”.
Any help to solve this issue?

hmm that sounds crazy. idk how this could be.....
but what you can do is:
1. download sony pc companion software & reset, repair or update the phone if avaiable.
=> if still bootloader unlock allowed: NO then:
2. download & install flashtool. after iit install install its drivers from flashtool/drivers folder (need your phone driver + fastboot + flash driver) optional: install android SDK. (just leave all it is & press install packages.) if you done, flash a stockICS.ftf (<= firmware) like shown on this page: http://talk.sonymobile.com/t5/Android-development/GUIDE-How-to-Install-Jelly-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389 (you can download the firmware there, just make sure you choose your model right. use ICS .587) (boot once)
now look if bootloader unlock allowed....
if still : NO, then maybe ask your carrier where u get this phone. normally if your contract is end, they unlock your device for free (its here like that.)
you can also try just to request a code from sony site & try to unlock it maybe you are lucky. (you said you was allowed on pre version)
good luck!!!
the thing is if your bootloader locked = no cutom kernels = NO JB or KK rom for you. only stock based custom roms for locked bl...

[Q] C6833 Sony Z Ultra - Can not enter fastboot but flash mode?

Hi Dev's,
verified the bootloader can be unlocked via *#*#7378423#*#*
installed the fastboot, flashmode & sony xperia z ultra drivers from the flashtool 0.9.18.2 installer (flashtool.net)
on windows 8.1 with deactivated driver compatibility check.
Now i've tried all 3 methods to enter into fastboot mode from here
(theandroidsoul.com/sony-xperia-z-ultra-fastboot-mode)
via volume up + usb in, adb & quick boot reboot (even if the device is not rooted at the moment)
, but no success. The device always starts into flashmode, and this is the only state being recognized by the flashtool in windows. All hardware keys are working fine.
Any more ideas how to enter fastboot? I am really stucked at the moment.
Thank you!
what does it do on vol down and usb in?
You are doing this from a powered off state?
Hi,
I really tried every method and button combination. it is just the same as in this thread I found later.
http://forum.xda-developers.com/showthread.php?t=2716418
Seems like the fastboot mode is being hardware locked or something.
I return the device tomorrow, and check a new one (if I get) with android 4.2 stock Rom.

I had this same problem some months ago .Never saw a way around it . Since the phone was still like 1 month old I had to return it to sony and got a new one !
Lots of guys helped but was no way to get it working , even had to borrow 2 different laptops to try it

Bricked my phone please help

Okay, so i am using a xperia z2, cant rmb the version of the firmware, but i successfully rooted my device so i went on to try and flash cm11 onto my device. However, upon flashing cm11 and gapps into my phone through dual recovery i was no longer able to boot up my phone. Holding the power switch causes the device to vibrate, like perhaps every two seconds, but does nothing meaningful. Holding the powerswitch and the volume up key boots into fast boot, which is just a blank screen, but with the blue led that i read on the internet meant fastboot. Problem is, I am unable to get windows to install the relevant drivers for S1 Fastboot as it is displayed on my device manager window, and nothing i try will help. Ive downloaded usb drivers from numerous sources, including but not limited to flashtool, and nothing can get the fastboot to be recognised by the computer. Kindly advise on what i could do to restore my phone please! any help is greatly appreciated!!!!
I live in Singapore and i understand that bootloaders are by default unlocked? I'm not sure if i have to install any form of kernel , but i have a feeling this may be the cause of the problem? Please be kind, I am new to this entire rooting business. Once again any assistance is greatly appreciated!

Folow this to unbrick your device
You need an unlocked bootloader to flash cm11, no bootloader comes unlocked
There is unlockable and non unlockable

M4 (E2303) stuck at Sony Logo - bootloader is not unlockable - Have NO recovery

Hi - have been searching these forums for days now but cant find a solution.
I am OK at flashing etc but am stuck now. Phone is stuck at Sony logo and won't go any further.
Phone is an Xperia M4 (E2303) and the bootloader is locked - have tried unlocking it but get 'Failed - command not allowed' so i'm guessing it is not unlockable!
I can't get into recovery (nothing happens when i try) and cant get into FlashMode either. I plug usb into phone while holding the volume down key. I CAN get into Fastboot mode which seems to work fine and is recognized ok by PC - drivers all installed ok.
Is there a way of flashing an FTF using Fastboot rather than Flashmode? or even installing any recovery. I have 32 and 64-bit Flashtool installed, i have FTF files and i have EMMA.
Can anyone help please? I would be very grateful - many thanks - ian
With bootloader locker you won't be able to flash anything. I had the same problem.
Desperately, my friend thought it was a good idea to put the phone on the refrigerator for a while.
Surprisingly, in the next day, I turned it on and the cold phone booted normaly and then I was able to set OEM unlock authorization on developer settings and unlocked the bootloader with sony unlock key.
Then I tried to flash a twrp, but I'm stuck back on boot loop again, and fridge didn't help this time.
Power OFF phone, then hold together for at least 30 sec in this order "volume down" + "volume up" + "power button". Then release 3 buttons and try to power on phone with power button. This procedure will revert your phone back to default settings.

Hi there,
Same problem as OP here.
I am trying to revive my wife ex-phone, model 2303 which has been forgotten for two years at least.
Stock rom
No root
Bootloader locked
Stuck at Sony Logo when starting up the phone.
Can boot in FastBoot (blue light) and is detected by PC
Can boot in FlashMode (green light) but PC doesn't detect anything. Nothing appears in Peripherals.
Any advices ?
What can be done in FastBoot mode with a locked bootloader ?

Also Xperia companion will install all needed drivers and could also recover device.

Thank your for your advices.
But in Flashmode the phone does not even appear in computer peripherals manager.
In FastBoot, Sony Emma does not detect phone neither.

Have you tried using an older version of flashtool ?
Hi, sorry for the late reply.
Which version of flashtool would you recommend ?
Would it change anything as the phone is not detected in device manager anyway ?
