[Bootloader][E2303][26.3.A.1.33] Unlocking bootloader - Sony Xperia M4 Aqua

Hi,
Services info say "Bootloader unlock allowed: Yes". If I unlock bootloader via fastboot it will hard brick my phone?
I must check "allow unlock OEM" in dev options?

Yes, you have to check it. It can soft-brick phone, if it happens just flash FW via flashtool(ANDROXYDE' S, NOT EMMA).

Ok, thanks. And one more... if i flash boot.img with recovery it will corrupt boot or any other partition?

To relock the bootloader, just flash an official miui fastboot rom via miflash and you're done....
If you have unlocked officially, you can just unlock your bootloader anytime without asking permission from xiaomi again...
If you have unlocked your device unofficially, repeat the steps you did for unlocking your device or unlock officially.....

The steps to be followed are following:
(1) Turn on USB debugging for your phone;
Go to Settings -- About Phone --> Touch 7 times on "MIUI version" to Enable Developer Options.
Now go to Settings - Additional Settings - Developer Options --> USB debugging.
Enable USB Debugging and Connect to PC.
(2) Download Fastboot ROM (file extension .tgz or .tar) from
Code:
http://en.miui.com/a-234.html
(3) Boot into EDL
adb devices (to check it's connected)
adb reboot edl
(4) Use MI Flash Tool to Flash the Fastboot ROM
One done it will be locked... To relock follow same steps as done earlier - either official or unofficial

Locking and unlocking bootloader on stock ROM&Recovery

Hi!
What happens if you don't have permission to unlock bootloader and you still try to do it using fastboot oem unlock on Xiaomi Phones?
I have already got the permission and I've rooted my phone, so I didn't really try it because I was simply afraid. Has anybody tested that?
Also, if I relock my bootloader again using fastboot oem lock, will I be able to unlock it using fastboot oem unlock or will I have to use MI tool?
Aaaand the last question - I haven't installed custom rom or TWRP - I booted TWRP using fastboot boot xxx.img, then installed SuperSU package. Is it dangerous to lock bootloader with phone rooted? Recovery is still stock, so ....

[HELP] Relock-Bootloader [ZB553KL/ZD553KL]

Does anyone have a method of re-locking the bootloader of ZB553KL/ZD553KL or remove the bootloader warning splashscreen?
You can relock the bootloader through fastboot (fastboot oem lock), but make sure all your images are original or you'll bootloop until you unlock the bootloader again, which sometimes can't be done through fastboot.
