[Q] Wt19i - Question regarding access to fastboot & unlock bootloader

For the sake of this question I have a locked bootloader on a wt19i. The phone is rooted. (It's my friend's phone but I'm voicing a theory). It can't enter fastboot mode and the bootloader unlock status is: not allowed.
Armed with the IMEI number,
If I did a TA backup via Octopus Suite 1.0.3,
Then, (following methods seen in this thread: http://goo.gl/QNKxS Third post down.) to force the phone into fastboot, start a firmware (re)install in PC Companion. During that process the phone will enter fastboot mode. If I stop the process there [in Windows Task Manger], then the phone will get stuck booting only into fastboot mode (until I finish putting firmware .tft back on it).
THEN I use SE Bootloader Unlocking v1.6 {Found here: http://goo.gl/JxDmY }. I give it my IMEI, it gets an unlock code and I connect the phone - in fastboot - and select "Unlock BL" to unlock the bootloader.
Then restore TA, followed by a restore of firmware.
Would this unlock the bootloader or brick the phone?
Corrections and answers welcome.

I checked the thread you were referring to,
the process they are doing there is to access flash mode...
fastboot is completely different, can only be accessed if bootloader is unlocked.
based also on the bootloader unlock status: not allowed, this means phone is network locked, unlocking of bootloader would not work thru available methods in xda.
you would to pay in order to remove the network lock and then unlock bootloader
Would this unlock the bootloader or brick the phone?

This would not unlock the bootloader,
Brick the phone, not sure, but it would probably wont, good thing you have a backup.
You can always do a flashing of stock firmware thru flashtool or wotanserver.

You can't unlock if it says

If it says

then you can unlock, look in my signature for a guide.

your bootloader is unlocked.
You can check the state if you boot phone up, open dialer, type *#*#7378423#*#* -> Service Info -> Configuration
Please tell us what it says there, then we can help you

The problem is you tried to use that tool and the moment you have typed your IMEI and pressed get unlock code, you lost your warranty. So you have no warranty anymore!!
Now you will have to desimlock and after that you can just hope fasboot is enabled.
Install flashtool, open the installation folder > drivers and install all drivers for all devices. Install the android sdk (please better look in my signature to see how to set up android sdk and flashtool and replace the usb drivers). Then try to enter fastboot mode like explained in the threads

[Q] XZU Bootlooping NO Recovery LOCKED Bootloader

Hey guys,
I just experimented with some sound libraries and so on...
now my device is bricked.
I don't get into recovery (pink led, not turning on), flashtool does not allow me to reflash the stock-rom, and fastboot-flashing also doesn't work, because my bootloader is locked.
Is there any possibility to unlock the bootloader from outside, without having the stock-rom running?
Or any other possibility to get this thing working again?
Would be really happy, if someone has an idea
Thanks

Flashtool (EMMA) says, my bootloader is locked -> I have to unlock it but thats not possible without a running system. for flashtool I just pressed vol down and put the cable in like it is described everywhere.
for fastboot I did the same, but vol up. Then the LED turns blue, but I can't even reboot it via fastboot command.
USB-Debugging is also deactivated, so I don't know how to access the phone.
EDIT: just tried again: reboot over fastboot works, but erasing or formatting is not allowed. Flashing not possible because there is not enough space it says
EDIT II: ok, just got the bootloader unlocked via fastboot. now trying to get the stock system on to enable usb debugging and flash custom rom then
EDIT III: just solved it. how? 1. Unlock bootloader via fastboot 2. let EMMA do a service 3. enjoy again

i think i wrecked my phone any way to recover it

i couldn't get twrp to work on my xperia zr so i tried this open cmd put the phone in recovery mode i think (blue led) then "fastboot flash boot TWRP+RAINBOW2.8.2A.img" then "fastboot reboot" the phone is dead just a red led and a small vibration when powered up but nothing light up any help ?
edit : i boot it again the Q now is there any way to install this recovery TWRP
Depends on if your bootloader is unlocked. I don't know about the ZR specifically, but the majority of newer Sony devices need either bootloader unlocked or to use a special kernel+recovery combo that must be installed through the flash tool for devices with locked bootloaders.

Unlock bootloader

My Z5 compact was updated to Nougat using the OTA service.
The bluetooth integration to my car stopped working and I read that this was a noted problem I decided to flash my phone back to Marshmallow.
I'd installed custom ROMs on previous HTC phones following info from XDA so was pretty confident.
After following the Sony guidelines and obtaining my unlock key I am unable to get it to work in fastboot mode.
I suspect that it is a USB problem at one end or another.
If I connect up the phone to the PC using the original lead I can find it using adb devices and the device is showing up as error free "Sony sa0113 ADB Interface Driver" in Windows 10 device manager.
However the phone isn't charging and I can't get it into Fastboot by holding the up vol key and plugging in the USB lead.
I can get a black screen with the blue led by running adb reboot bootloader and the phone is recognised from fastboot devices but when I try to unlock the bootloader I get an error:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot -i 0x0fce oem unlock 0xB4D9AxxxxC359F2C
...
FAILED (remote: Command did not succeed)
finished. total time: 0.042s
Any help appreciated.

If feels like I haven't go the fastboot USB drivers but I can't see how or where I can add them.
Any help appreciated.

Thanks. I think I am OK there because I accepted the drivers from an unverified source during installation.
Also I can see the phone with both adb devices and fastboot devices
However when I run adb reboot bootloader the phone reboots but comes up with a blank screen with the blue led.
adb reboot bootloader just goes into bootloader mode and not fastboot mode which is needed to unlock it. Go directly into fastboot by typing adb reboot fastboot
Then when your phone led is flashing blue, run your fastboot "oem unlock" command.
Saw now that you already tried that sorry about that.
Tried running cmd with admin privileges to see if that shows any difference?
Also from sony:
Please note! It will only be possible to unlock the boot loader for certain releases. You can check if it is possible to unlock the boot loader of your device in the service menu by following the steps below:
In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

You don't need to unlock your bootloader to simply downgrade to official MM! Just use flashtool to flash the appropriate MM ftf. There are plenty guides available on XDA and elsewhere.
I'm lost in your explanation.
You wanted to unlock your bootloader to be able to downgrade your phone? That's right? And it's fine to me, but you don't need to do that if you don't feel like. Unlocking your bootloader is nog necessary to downgrade to MM via flashtool.
So you tried to unlock your bootloader. But what you write what happened afterwards is completely unclear to me, because it contradicts itself.
-->> "Also I can see the phone with both adb devices and fastboot devices"
Fine. This means your connected with your phone and fastbook recognizes your phone. So bootloader is unlocked and software to control that works fine.
-->> "However when I run adb reboot bootloader the phone reboots but comes up with a blank screen with the blue led."
Fine, so you unlocked your bootloader, and rebooted in fastboot.
-->> Obviously. It's an unlocked bootloader, you can double unlock it or something like that. You can relock it if you want (which doesn't make any difference for what you want to do) but that's a different method.
Is there any reason that you absolutely need to a second method to enter fastboot mode? Or any fastboot mode? It could be possible with another kernel, but I don't see the point to flash another kernel. I would just leave it like it is.

that is notmal behaviour, that is fastboot mode, indicated by that blue LED
Thanks for the clarification that I don't need to unlock the bootloader to downgrade using flashtool. What I didn't say was that I couldn't reinstall Nougat using the Sony tool software restore option or get anywhere with flashtool because the phone won't go into the blue led mode by inserting the USB and holding the up vol button. I did try running flashtool in one window and the command line tools in another with the idea of running flashtool first and then unplugging the phone and replugging it to use command line to get the blue LED state, but that doesn't work because the command line tools can't see the phone once flashtool is running and has addressed the phone.
From what i read, i assume you are on nougat and want to go back to MM, right?
So you would need flashmode instead of fastboot mode.
You get there with holding Vol down button and plugging in USB cable on turned off phone.
Flashmode also shows a green notification light instead of the blue one.
If you having Problems to get there, please check following:
make sure to have latest version of flashtool installed http://www.flashtool.net/downloads.php
install drivers from your flashtool\drivers folder
don't use an USB 3.0 port or cable(have heard of some people having trouble with)

OP, I had the exact same problem as you. At the time I tried absolutely everything but never found the culprit. So after several months I actually succeeded today
This is the guide I followed - https://forum.xda-developers.com/z5-compact/general/guide-how-to-root-z5c-painful-using-t3549388 and it worked perfectly.
A few pointers:
- Go to the service menu (*#*#SERVICE#*#*) before you begin, before you turn OEM Unlocking ON from Dev Options .
- Take note of what it says in Configuration and Firmware.
- Now enable OEM Unlocking and take note again, it should say stuff like Model Number: Unknown and other unknown stuff.
- Reboot - IMPORTANT.
- Use the guide I gave you and you will be fine, it took me ages to find a solution but now I'm on MM and rooted
Hope I helped :fingers-crossed::fingers-crossed::fingers-crossed:

G8343 fastboot commands not completing

I just purchased a G8343 on eBay and have attempted to unlock the bootloader, but the OEM unlock command seems to merely hang every time I run it.
By sheer luck, the bootloader ended up unlocked, but when I try to flash recovery, the command also hangs—this time without leaving the recovery actually flashed.
I can't restore with Xperia Companion as the bootloader is unlocked and Flashtool doesn't work to flash the device. Sony's official Emma also appears to not want to work with the device, stating "No available services for this model"—presumably because the G8343 is not listed on the officially supported devices for Sony's "Open Devices". I've even tried newflasher but that times out in fastboot as well.
What do?
To flash the recovery, make sure it is powered off and UNPLUGGED. Then plug in the phone while holding the Volume UP button. You should see a blue LED light.
Then check windows device manager and make sure to install the Android Bootloader drivers are installed. Then you can freely use "fastboot flash recovery twrp-xxxxx.img" easily.
You can not flash recoveries the same way you use Newflasher, since that uses the flashmode and not fastboot.
