First of all, if you want to unlock your phone, check the date of manufacturing first! It is well documented here plenty of examples of newer phone brick when unlocking bootloader, so better be careful!
Secondly, if you ran into problem, you need to re-lock your phone using flash tool. Then re-unlock again! I previously lost my phone GSM radio when unlocking bootloader (while on GingerExperia). I have to flash into stock ROM (it's a must) using flash tool, and relocked again.
Finally, it is safest to unlock bootloader in stock rom.

No, you don't need to unlock it again. BL is the flash partition of the phone, what contains a secret code. When you unlock the BL, you'll remove the code and the flash partition will be open. When you flash a new ROM, it changes the system partition. When you flash a new kernel, it changes the flash partition but nothing else. So you'll not need to unlock BL again.

Yes and No
You only need to unlock the boot loader IF ...
a) you checked that your phone is safe for boot loader unlock.
b) you want to make use of a custom ROM that REQUIRES a custom kernel
ROMs where the description says "STOCK" or "Stock Kernel" also run on the default Kernel - and are the only ones you can use if you can not unlock the boot loader on your phone.
Please see the "Hard brick warning - Read before boot loader unlock" Sticky in the X8 General board to educate yourself on the matter.
Hello,
Is it possible to flash rom without unlock?
I think I saw it somewhere that you can flash recover temporary without unlock, then maybe flash a rom in the temporary recovery?
Hi,
No you can't. You must unlock the bootloader, flash a recovery, root your phone and then you can flash ROMs
No, it is not possible. To boot or flash a custom recovery you need to be unlocked.

Is your bootloader unlocked? You need an unlocked bootloader to flash a non-stock based custom roms. Since you can connect it to flashmode, download flash tools and flash back a stock rom. You can unlock your bootloader if you want flash flash a custom ROM.

now im downloading kitkat 4.4.4 to flash and then i will root with the new tool ,, i need to what is the next step to flash recovery and custom firmware and mods
i read about dual recovery , fastboot ,flashtool , boot loader , unlock boot loader but i dont understantd so if anyone can help me in this !!
If you root with the newtool it will install recovery as well.
Dual recovery is just a recovery package that gives you the option of 3 recoveries
You do not need to unlock the bootloader to get recovery, but you do if you want to flash a custom kernel.
i rooted now using the new tool from this topic and nw i have recovery .. can i flash custom roms ?

From the development section yes.
If you want to flash custom roms from the original development section you need to unlock the bootloader

yes you can flash custom rom base on sony stock, not AOSP (CM, PA, AOKP...)
i didnt get it !! what is the difference ? and how to unlock boot and is it dangerous ?
The difference is the kernel. Locked bootloaders will not boot on a custom kernel. In order to unlock your bootloader just Google "Sony unlock bootloader "

ok what i lose if i unlocked bootloader ? and is it easy to lock it again or factory reset ?
Hi all,
I have a Mi 9 europe version and want to get back to stock.
The current status of my device is:
- Bootloader unlocked
- TWRP
- flashed GSI FlokoRom
Can I just put the phone into fastboot mode and flash (10.2.24.0 PFAEUXM from there) with MI flash tool as mentioned there? Is it possible to relock the bootloader after this or will it brick my device?
I recommend you to flash rom WITHOUT LOCKING at first time. Even if something is wrong you should be able to flash twrp and then flash any rom.
But if after flashing your ohone boot up normally, flash it again and tick LOCK BOOTLOADER. Simple and secure way to get stock phone.
