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.

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.

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?
I am assuming your phone can be bootloader unlocked and you have unlocking key from sony.
If you don't know then refer to this post http://forum.xda-developers.com/showthread.php?t=1527159
WARNING: IT WILL WIPE YOUR PHONE DATA SO MAKE BACKUP
1. Install Flashboot and Fastboot drivers of Flashtool (setup file will be on C:\Flashtool\drivers or similar place).
2. Turn on your phone, and connect with usb debugging on.
3. Go to Plugins-> Bootloader Unlock option, start it.
4. Now it will ask to disconnect your phone and reboot in FLASHMODE.
5. Again reboot your phone in FASTBOOT mode.
6. It will show a window with your IMEI number, insert your unlock key and click "unlock".
7. The device will reboot and you are done!
FLASHMODE

When I am installing drivers, I am getting "don't install or install anyway", I choose install anyway but the same window comes up again. Should my phone be turned on, off or in flashmode or something?

If you have installed Flashtools and its drivers correct you shouldn't get any driver prompts when plugging the phone in
Assuming you did a default install browse to C:\Flashtool\drivers and execute the drivers file. Make sure you select the drivers for you phone ie "Xperia U" and scroll to the bottom of the list and select Flashboot and Fastboot drivers. From what I have seen so far most people are not installing these 3 drivers.
karimkahale: I would go back to the Sony website and get your unlock code again. Maybe you entered some wrong details...

Successfully installed Fastboot driver on windows 8 (Used Advance Startup for installing unsigned drivers)through Flashtools and also unlocked bootloader..
Accidently lost all data as unlocking bootloader wipes data...forgot to take a backup but m happy.
Thank you for this tutorial mate!

Thanks a million, but would my warranty be void immediately after I unlock the bootloader, what's the regulation about this matter, I'd like to keep my warranty.
---------- Post added at 10:00 AM ---------- Previous post was at 09:45 AM ----------
If i relocked the boot loader the warranty wouldn't be void, right?
Not quite;
It all depends on your repairman...
The standard, though, is, that the warranty is valid if the guys at the repair center can flash a stock ROM (.ftf) onto the phone. Some phones can do this without their bootloader being locked, but some can't do this after their bootloaders are unlocked, even if they are locked back afterwards...
Now, I have a question:
I'm having the same error as karimkahale...
Whatever I do, I get that stupid error, and not even Sony can help me (their support team (that needs a week to reply to a simple e-mail) said that thy don't know how to help)...!
Thanks a lot for the guide, it was really helpful!
Cheers!

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...
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.

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 ?

Hi,
I'm quite new to the world of custom roms and I would appreciate some help to get my z3 tablet working again. I wanted to install this ROM as my Z3 was still running on Lollipop with no update in sight.
I managed to unlock the bootloader following the instructions from Sony's homepage and I was able to flash TWRP using the version provided in the thread linked above. Unfortunately now I can neither boot into recovery nor do anything else with the tablet except start the fastboot mode (solid blue light after holding power up and connecting the power cable).
Is there any whay to start TWRP? Did I use the wrong image? I'm on Windows 7 64-bit. Thank you for your help!
I used this solution to get out of the very same situation on my SGP611.
If your tablet is soft bricked, stuck at boot, restart display SONY and keep restarting you can do the bellow steps, but after that you will need to root and install TWRP again.
To turn off your tablet which is keep restarting, press and hold POWER and VOLUME UP until the tablet vibrates 3 times and turns off.
On your PC open Sony Xperia Companion, click Software repair, check My device cannot be detected or started, Next, chose Xperia phone or tablet, Next, check I know my Google credentials, wait until instruction are displayed how to connect to your PC.
Make sure your tablet is turned off, press and VOLUME DOWN while connecting the USB cable to PC, when the program starts the next step you can release the VOLUME DOWN.
Now wait and do not disconnect the tablet from PC.
Hi, I used Lightheadeds link and I managed to install the stock rom that way. I also tried luk71s solution but Xperia Companion did not work because my tablet has an unlocked bootloader.
Many thanks, I now have a working tablet again!!!

Since you already unlocked your bootloader it makes sense that you do not have an OEM unlock option. In developer settings you must enable USB debugging and reboot in bootloader mode to flash twrp. What happens if you send the command 'fastboot devices'?
Thanks for replying my Sos.I did not have the unlock oem optoon before unlocking the bootloader. When I write adb devices the computer sees it in normal mode but does see the tablet in fastboot mode.

I checked my tablet and it has no OEM unlock option either, so maybe it is simply not implemented. This means you should be able to unlock.
To see your tablet in fastboot mode you must install the correct drivers on your PC. For me the easiest way was to install Flashtool from www.flashtool.net. It has an option to install drivers and it is also useful if you want to go back to stock. You may also want to backup your TA partition if you consider returning back to a pristine state.

Z3 tablet Root 2018
So I finally managed to root my lovely and Tiny Tablet. Info those interested.
Step by Step. My machine Windows 10 Pro 1803 : Did not work with this computer and changed on a second one Same windows Pro 1803
that does not mean it will not work on yours)
Phone is Z3 Tablet Compact with Marshmallow.
A On Computer
1 Installed Flashtool 64
2 Installed ADB FlashTool 5contains drivers also)
3 Installed Phones Driver (it may be included with Flash tool)
4 Installed Sony Flashtool
5 Unlocked Bootloader with Flashtool or Go to Sony's Site to obtain Unlockboot loader Code. Sorry Too long to explain ( I used Flashtool)
6 Downloaded SGP621_23.0.1.A.0.167_CE.ftf or other Firmware that fits you xperia device with Sony Flashtool :: ATTENTION This downgraded my phone to Android 5 Lollipop.
ON Phone
If you are here, you already know that you have to unlock your Developper mode, Allow Debbuging mode, Allow mock locations, Go to de security option and allow Unkown sources.
1 Installed Kingroot 4.50 (Install it even if Google says it may be dangerous)
2 Ran Kingroot 4.50 IT IS NOT the latest but it worked for me on Android Lollipop. (I had tried the lastests versions of Kingroot, Kingoroot, and other it did not work on Marshmallow and it did not work for me)
It did not work the first time. SO i tried a second time as proposed and it then worked.
2 bis I rebooted verified with a root checker afterwards: Rooted Yeeeeeeeeeeeeeeeeees
3 Then downloaded Root checker, Titanium Backup, Rom Manager, Official TWRP,SuperSU,Busy Box
4 Once rooted, I removed purify that came with Kingroot and other bloatwares and Installed the above apps. You don't have to do it but that is what I did.
As from here, you choose what you want to do. You are FREE to debloat and install what you want.
I will like to thank all the developpers on this site and thoses who a have showed my ways to find a solution. It is not always clear. But atleast they have tried.
So I am transmitting my experience for others.
Second stage finding the best Nougat or Oreo setup for me in a week or two.
Have a nice day
