Why don't you read official guide?
http://developer.sonymobile.com/unlockbootloader/

-i ?
check your USB-driver (if on Windows) and fastboot binary
on Windows 10?

i think u need it for rooting?

I don't even get to fastboot part - every time I reboot with adb reboot bootloader the tablet goes into some mode with a black screen, green led indicator and fastboot devices returning nothing.
At the same time the device is recognized by windows as something S1???? and unknown driver, and I totally failed to find a proper driver for that.
Any help will be appreciated. Btw, Windows 10 here

Which one...

Some bootloaders are unlockable. Mine is the same way. I have to wait for a root method that does not unlock the bootloaders.

= you can unlock them
to be expected with SGP712 and SGP771
Maybe with some provider branded Tablets in Japan they are "not unlockable".

ONLY ROOT.

Hello ?
I'm looking to root my m4 aqua E2303 6.0.1 Bootloader unlock: yes
However I don't want any twrp stuff, last time I rooted this phone I found something on this forum, connected my phone to a pc via USB ran an exe and it got rooted it was soooo simple, and everything worked great, however after Sony released the firmware update(from 5.0.0 to 6.0.1) root dissappeared. Isn't there a similar tool for 6.0.1? I really don't want to get into all the twrp stuff and ehhh you understand, I want to keep it simple.
Thanks in advance.

in Android 6.0.1 Without Unlock Bootloader is Impossible, but if you have Unlock Bootloader Use it,( Just Flash boot.img) : http://forum.xda-developers.com/m4-aqua/general/root-twrp-sony-xperia-m4-aqua-t3503369
And you can try KingoRoot Soft for root without Unlockbootloader
Whaaaaatt?

Let me explain, I'm doing the adb method, when I say fastboot flash boot boot.img it just says waiting for device
My phone doesn't react at all
I haven't manually unlocked the Bootloader it's so hard and time consuming to download all those programs.
I want only the root nothing else.

I just open a command prompt in the adb folder and type it, it says command line is not allowed even if I try doing it in the administrator rights.
First it says max file size
,,OKAY"
Loaded(0.703seconds)
....,,boot"
Failed(command line is not allowed)
Something similar to this.
What am I doing wrong? How can I check if I actually unlocked the Bootloader(pretty sure I did)
So weird.

Cannot flash boot new XZ1

Hi, I'm having issues trying to root brand new XZ1 following this guide: https://forum.xda-developers.com/xperia-xz1/how-to/guide-how-to-persistant-root-xperia-xz1-t3718375 .
When I try to fastboot flash G8342 boot img I get "Flashing is not allowed in Lock State" error. I have made sure that OEM bootloader is unlocked in developer options...
I have tried updating drivers, using different boot img no luck. Anyone know what the solution is?

Sounds like your bootloader is still locked, just because you flipped the OEM switch doesn't mean it's unlocked... Go read over here before you do anything else.. ( https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/ )

Thanks, that's a good guide. But when I try to run "fastboot -i 0x0fce oem unlock 0x<insert your unlock code>" it always returns that the command's syntax is incorrect. Is this because I don't have 26.0.2 platform tools?

Actually I sorted that out, I was entering it with the brackets when I was meant to remove them. But when I enter it now, it doesn't tell me incorrect syntax, but tells me instead "unknown option: -- i" I wonder if this is an issue of using too new version of Platform tools? (I'm using 28.0.1)
Right I figured it out. Just omitted the -i option and it worked. So it looked like "fastboot oem unlock 0x<unlock code>"
no further issues cheers
I get same problem (bootloader unlocked, OEM unlocked .....But show I'm in lock state)

Google 'unlock xperia bootloader', and check the xz1 compact forum for the DRM backup method for your phone. (I know you said you have a xz1)
You need to unlock the bootloader using a code from sony, and enter it via a fastboot command before twrp can be booted/installed.

How to relock bootloader?

The "fastboot oem lock" command does not exist, it is certainly not a normal way
The best method to lock bootloader is searching for the Service rom on https://androidhost.ru/ and doing the dload method. Process will erase all the data from your device !
(Before you do anything, read carefully Software Upgrade Guidline in "ReleaseDoc" . With Service ROM you will get full stock with locked bootloader (warranty will not void any more).)
Hi thanks a lot for your reply, Unfortunately I cannot find such rom on the site for the life of me.

I see your replying to my other thread aswell, no point having 2 so I will carry on here.
I have downloaded a rom called Huawei P20 Lite ANE-LX1 ANE-L01 hw eu HLRCF Anne-L01 8.0.0.167(C432) Firmware 8.0.0 r1 EMUI8.0 05015ACF [androidhost.ru] so I am going to try this with HuRUUpdater 0.4

Strange, maybe you tried to install some firmware manually before, hm?
Connect your phone in fastboot mode to PC , open 'Minimal ADB and fastboot' and use command
fastboot oem get-build-number
Unfortunately not even HuRUUpdater 0.4 is working with this particular rom it reports unknown error so I am at a complete loss really

P20 lite unlocked bootloop

Hello guys I'm trying to save my bricked P20 Lite but I am running into some issues. I unlocked the bootloader using testpoint but twrp won't flash or boot. Flashing gives me a flash write failure, booting gives me a invalid command error and I can't wipe cache either. I could really use your help.

"flash write failure" - it might be due to a locked bootloader or hardware issue, AFAIK.
Try explaining what exactly happened, step by step.

Are you sure that bootloader is unlocked? (With unlocked BL you will see that message each time when you reboot: "Your device has been unlocked and can't be trusted").
Have you enabled in Developer menu
"OEM unlock" ?
In fastboot mode run commands :
fastboot oem get-build-number
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the results.

Probably your emmc memory is fried. Not being able to unlock BL & FRP permanently is a sure sign. But I'm just an amateur and an android fan, maybe I'm wrong.

Nope i already know it was dead (repairs say it was total loss) but when I saw the new unlock method I thought it might be saved. Guess I was wrong but oh well I tried anyways.

Question how to use Magisk root this device ?

i try the version of Magisk 23.0 but this is not worked.
It's the same with all other Xperia devices without customise recovery.
You first use Unsin (can find it in XDA) to the boot_blahblahblah.sin from stock firmware for unsin it. Therefore you will see a .IMG is generated.
Second, you transfer the .IMG to your phone, and use Magisk to patch (install - select file and patch) the boot file.
After it's patched (you can find it in the Download folder). Transfer the patched one back to your PC, and make phone enter fastboot mode (or the blue light mode). Then you run this command on Windows Shell (Google it, it's easy)
Fastboot flash boot the_file_name.img
After it's done, boot into your phone, you can find icon of Magisk, install it, and your phone is rooted in this stage.

Sorted it? Rooted mine earlier on. To unlock the bootloader you can just pick Xperia 1 or 1II it doesn't matter 1III will be added eventually but doesn't make a difference.
