Well,
Some time ago, with the method of flashtool, turned to lock the bootloader ... but now when I try to unlock send me error that the command is not allowed or command did not succeed.
Look for several part but there is no concrete solution and wanted to know if there is someone here who has been able to solve this problem.
Thanks!

(Before anyone says use Google, I have searched EVERYWHERE. I have been trying to unlock my xperia z's bootloader for hours and still no dice.)
I really need help unlocking my bootloader. I know I can unlock it since it says Yes in the service menu. I've been trying both fastboot and flashtool, but none of them seem to work. It keeps saying FAILED <remote: Command did not succeed>. However, if I try to unlock a second time in a row, it will say Okay. However, the phone will then reboot and be stuck in a bootloop. I would then restore it and the bootloader is still locked.
Does anybody have any ideas what is going on? I have tried to unlock on multiple PCs, with Windows 8 and 7.

Hello, i have some trouble to unlock the bootloader of my Sony Xperia E1.
A staff member from support lead me to this forum. hope some people can help me.
After receive my unlock code, i follow the steps from the guide from sony to unlock my device.
But the last steps look tricky.
I´m not sure about this line, after command "fastboot device":
12efd65c fastboot
And command "fastboot -i 0x0fce oem unlock 0x...insert key...." tells me <remote: Command did not succeed>
I try it a lot of times but doesn´t change. Only effekt is the phone loading endless in this blue loading screen and
i have to use this Sony PC Companion to repair the phone, after each try.
Have anyone a idea for this problem?

I sent the IMEI number to Sony web developer, then they gave me the code to unlock BL.
But when I get the phone into fastboot , type the code to Unlock BL, nothings happended. Just got back a message:
" FAILED! <remote: Command not allowed> "
I used the lastest Flashtool v.0.9.223, but it fail.
I have already installed the drivers of Sony Z3+, PC have recognized the phone in fastboot,flashmode,MTP mode, but I could not unlocked yet !!!

Flash tool has drivers and a handy app once you have unlocked you're bl.

Hi all,
I recently unlocked the bootloader of my old Sony Xperia XZ2, which I bought from my mobile carrier in Peru, following the steps in the Sony Developer World page. It worked as expected, the bootloader was unlocked. However, when I installed another ROM to have Android 10, I saw the annoying message others have reported (here and here), "Your device software can't be checked for corruption. Please lock the bootloader".
I have read that the DRM keys should be backed up before doing this process, which are related to the Sony features, I don't care about losing those at this point. Is there a way to relock the bootloader again?
I already tried fastboot oem lock and fastboot flashing lock with no avail, the message returned is FAILED (remote: unknown command).
Flashtool BLU option doesn't work either. When trying to run it, it shows the message "ERROR - Cannot invoke "String.split(String)" because the return value of "java.util.Properties.getProperty(String)" is null", which leads me to think it's trying to read a string from somewhere but it doesn't exist.
I've already flashed the original stock ROM from my carrier but all the commands I tried above return the same failure.
I've also found this tutorial that applies for the Xperia XZ1 Compact and says that unlocking the bootloader is not a reversible process. Is that true for the Xperia XZ2 as well?
Thank you very much for your help on this.
Best regards,
Jorge
Hello
I'm trying to Relock bootloader after it has been unlock with fastboot oem unlock command, and it seems an impossible mission.... I've downgraded to stock version thru EMMA FlashTool (Android 9).
The command I use is: fastboot oem lock and I get the following error:
FAILED (remote: 'unknown command')
fastboot: error: Command failed
Also tried thru sony mobile flasher by androxyde (Pressed BLU button):
Cannot invoke "String.split(String)" because the return value of "java.util.Properties.getProperty(String)" is null
Any suggestion anyone??
It's not possible to relock the bootloader of the XZ1C. It's a one-way operation. All of the threads giving information on how unlock mention this fact, as (I believe) does the Sony unlock pages.
Thus why you're getting an unknown command ... because there's no such action supported.
If I use stock ROM (Not custom) from Xperifirm, it can happend?
No ... it has nothing to do with the ROM that you're using, it's in the bootloader. Probably an e-fuse.
You can't re-lock it. Full stop. No caveats.
Ohhh
So no way to Relock the bootloader then?? I saw that many phone can....
Yes, some phones can. But definitely not all.
This is one of the ones that cannot.
I've installed kernel-G8441-47.2.A.11.228-hideunlock.zip and it works great!
One thing I can't pass - Google Wallet (Pay)
I didn't root my device, only unlocked the bootloader.
Any advice?
