Howdy,
I have an xperia z3 tablet compact, aka SGP621, which has a locked bootloader. I have currently rooted my Z3TC using this method but I want to be able to flash a custom rom. I understand that the sim lock is separate from the bootloader, but I've read in a few threads on XDA that the device needs to be sim unlocked to unlock the bootloader. Even after using sony's unlock page, the process fails with fastboot giving the following error:
fastboot -i 0x0fce oem unlock 0xC8267EA2C7B838AF
...
FAILED (remote: Command not allowed)
finished. total time: 0.009s

Can anyone confirm if the device needs to be sim unlocked to unlock the bootloader or if there is another method to unlock the bootloader ?
For anyone else curious, I got an unlock code from my service provider so the device is now sim unlocked. However, the bootloader is still unlocked. I am looking for a solution but its not looking good.
Also stuck with one of these. I can flash an ftf type file with the flash tool. Anything else it seems is out of the question.

Im back with another problem im now unlocking the bootloader and i followed the instructions from [PUDDING] International House of Pudding! BL Unlock/root thread so when i go into cmd and type "fastboot oem unlock" i get this message:
<bootloader> OEM unlock is not implemented
OKAY [0.000s]
finished. total time: 0.016s
any ideas?
It seems Pudding didn't take. If my memory serves me correct, the message you received is for when the bootloader is still "encrypted". Can you give a brief "step-by-step" of what you did and what you saw on your phone while using Pudding?

i used the instructions from here http://briefmobile.com/how-to-unlock-the-atrix-4g-bootloader and jumped to step 13 like it said in the guide cause i have 2.3.4 stock on my phone. i did what it said..got into fastboot mode, vol up to got into Fastboot protocol support mode and went into cmd found where i dl the extracted fastboot files and when i did the fastboot oem unlock i got that message on cmd
Unfortunately, that article was written before the "Official" release of gingerbread. At that time, they only had a "leaked" build that actually already had the un-encrypted bootloader. Since you have the "Official" build you will need to do all the steps.

I'm almost positive you will not lose your sim unlock.

I did a Google search and found a bunch of results of people saying that you will not lose the sim unlock by flashing custom ROMs and doing OTA updates. SO, I'm guessing you should be safe but, as always, use caution.

Hi guys,
First at all my phone said Bootloader unlock allowed: NO
but i do SIM unlock and now say Bootloader unlock allowed: YES
Whats mean this??
Now i can unlock my bootloader without any risk and install custom kernels?
Yes. If booloader unlock allowed turned to yes then u can unlock it.
One more question i tried to unlock via fastboot and appear
<bootloader> Unlock phone request
FAILED <remote: Phone is already unlocked!>
finished. total time: 0.004s

Bootloader unlock allowed . Yes
But in ur case it might be diff since u had a simlock
Don't forget to hit thanks
If you debrand with wotan BL is unlock automatically
But if you unlock with other method try to unlock BL with S1tool (testpoint method)
I need to do a warranty exchange and my bootloader is unlocked, how can i relock it?
How can i relock it without using a USB?
Cannot relock without USB. You would need to run
fastboot oem lock

Did you end up successfully locking it? Does it still display the 'unlocked' message on the logo boot screen?

Necro to say: YES, you can run "fastboot oem lock" to RELOCK the bootloader. "fastboot getvar unlocked" returns "unlocked: no".
Just tried it on my (two hour old) phone here.
Code:
C:\Assorted Programs\LGV10 Toolkit>fastboot getvar unlocked
unlocked: no

It will factory reset your device so make sure you are sure that you actually want to do it
reboot to bootloader then use the following:

Hi, Have you been able to Relcok it successfully? Does bootloader unlock still appears on your screen or it is gone?

I dont think my phone bootloader was ever unlocked, at least I never noticed such message, but since I rooted in lolipop I get this funny screen everytime I reboot, even after upgrading to marshmallow

if we relock the bootloader after doing root and debloat the stock rom, when they factory reset everything the root stay or just be gone after do the relock? are we able to unlock it again if we need TWRP?
other thing, the "cant check software for corruption" message will still appear or be gone when re-locked?
Hi guys!
A little background. I am trying to unlock the bootloader, after seeing the root status: unknown, a second time after re-flashing back to stock rom. I could unlock the bootloader perfectly fine on the first try on firmware .251 but after updating to .260, the
Code:
fastboot -i 0x0fce oem unlock 0x<key>
command keeps failing. I was trying to flash a custom rom from FreeXperia, but after several attempts of not being able to send the system.img into the tablet, I decided to re-flash to stock using Flashtool, and had selected all the option for wipe and no exclude.
Which leads to my question: Does the
Code:
fastboot getvar all
retrieves anything at all? I also tried
Code:
fastboot getvar boot
fastboot getvar version-main
but also retrieves nothing.
This is the log:
Code:

Hi, thanks for the reply! I was trying to get back root and unlock bootloader after splendidly failing to successfully flash a custom rom to my Z4 tablet. I was searching around Google for the remote: command not allowed error, and actually found out that some of the users actually have output for the getvar all command, which was bootloader version information and other stuff. I should also point out that I have successfully unlocked the bootloader the first time but not the second time.
Another question: Will downgrading the firmware change the rooting status in the service menu?
Edit: Will re-flashing the stock rom lock the bootloader?
Going to try the link you posted! Will report back if there's any disaster that I've made.
you better search here on XDA and not on the web
SONY devices are a bit special in terms of partitions and bootloaders:
http://forum.xda-developers.com/crossdevice-dev/sony/noob-guide-to-sony-ericsson-xperia-t3209012
AFAIK bootloader stays unlocked whatever you flash after unlocking and only using Flashtool or SONY PC Companoin (the latter useless for unlocked devices) you should be on the safe side.
fastboot flash ... is a bit more dangerous but I would never flash anything were I have a hunch the developer is taking too many chances and were there is no README. And it really has to be for your specific device!
Sometimes I think people complaining here have flashed obscure phone ROMs to their tablet or Wifi ROM to their LTE device or any weird pre Lollipop root tricks (there are scams easiliy found via web search).
I just tried downloading the Flashtool from Sony's website. The Emma one.
However, the program says that my bootloader is locked for some odd reason. I'm inclined to think I am in a state where I can't unlock my bootloader any more though.
I also did enable My Xperia after I reflashed the stock rom during the initial setup, but immediately deactivated it. I wonder if this is causing it to have this error.
the fora for newer Xperia devices are plastered with MyXperia "accidents"

Emma is useless. Does not work on our Lollipop devices. Updates of Emma seem to be automatic but no improvement. Maybe they forgot to switch off their update bot.
You bricked your device.
From SONY (READ before you do risky things!!!):
After unlocking your device, you should not enable My Xperia (found in the settings menu under security on some devices running Android 5.0) as this might cause the device to malfunction.

Oh ok, so there's no chance of me unlocking the bootloader? The device still boots up normally though.

I do not know.
I do not think so though - if you could unlock the MyXperia Software would be no protection at all. Thieves could just unlock the BL of the stolen device and lough at SONY.

You are lucky then - there are reports where only a repair at SONY could revive the device:

Alright! Thanks for the help! I guess no more rooting for me then. I'll try reflashing the stock rom again and see what are the results.
Reflashing doesn't change the rooting status. So a reminder to all: Don't enable My Xperia.

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.
