I have many questions with this bootloader. I'm new to this things. Sorry. Btw I have the J700F J7(2015) model.
1. Is there any way to know if my phone is in locked bootloader or unlocked?
2. I'm planning to install the Pixel Experience rom and I've read that i must unlock the bootloader first. I know that I must be from stock rom. Then I will install the TWRP, then root, then proceed to flashing the rom. In this process, where will I unlock the bootloader? Do I need it to be unlocked before I install the TWRP?
3. I know that I can google it, but is there an easiest way to unlock the bootloader?
Sorry, I have many questions.

Hi everyone!
I have a problem and I need your help. I'm using AVD Rom but I have locked bootloader ("Unlock bootloader allowed: no"). But I need help with flashing .zips. I was trying to do it via Flash Gordon but this application doesn't work properly for me and one time it caused bootloop in my phone. I wanted to flash Pure Performances™ but I don't know how. Does anyone know any program like Flash Gordon but more stable?
Thanks for help in advance

There are restrictions on CUSTOM ROMS which require UNLOCKED BOOTLOADER. However, some ROMS can even work on LOCKED BOOTLOADER. So every time you flash your ROM with locked bootloader, you will end up bootlooped. Sometimes, the ROM would work but some extra modifications wouldnot work (as they require further freedom which only unlocked bootloader can provide)/ Thus flashing Zips made for UNLOCKED BOOTLOADER will also result in bootloops.
The best way would be to check out which ROMS support locked bootloaders or if someone from your community comes out with a hack to UNLOCK your bootloader when you are not allowed.

I understand but most of zips caused bootloop if i flashed them via flash gordon. And I've read that Pure Performances modification doesn't need unlocked bootloader
Hi.. I have Sony Xperia (ST21I) with build number 11.0.A.4.27 (android version 4.0.4). Few months before it rooted this phone with a unlock flash tool. I am sure that the phone is rooted now. And i managed to install a Clockwork Mod too with CWM installer.apk file. And tried too boot into clockwork mod. It worked. Now I don't know which bootloader I am having? A locked bootloader or a unlocked bootloader. This question may look silly to people who are really fluent to android. I never carried any process to specifically unlock my bootloader. I am asking this question because I have read that "You can't root your phone without unlocking bootloader". If what i read is true does that mean i am having a unlocked bootloader?? So now is it possible to flash a custom rom for unlocked bootloader? Thanks in advance.
only few roms

Dial *#*#7378423#*#*
You probably have a locked boot loader as bootloader can only be unlocked by a specific key.
I too have a xperia tipo and it can be rooted without unlocking the bootloader. I used unlockroot to root it.
Thanks Guys!!

How can I unlock the bootloader on my rooted 5.1.1 d6603 eXistenZ rom without having to loose all my data? And if that's not possible, then how can I unlock the bootloader period? Does it matter if you're rooted and can you do it while on 5.1.1?

You always lose data when you unlock the bootloader.
It does not matter what ROM you are on or if you are rooted.
Any ROm that works on locked bootloader also works on unlocked bootloader
To unlock the bootloader go here http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Will I loose root and my dual recovery and if so is there root for 5.1.1? Thanks for the help.

No, (well you shouldn't) as root and recovery are installed to the system. Unlocking the boot does wipe data though.
And if once you have an unlocked bootloader you can always root any firmware on any android version. That's the main reason to unlock the bootloader. You will also be able to delete recovery from your system and have a custom kernel with recovery built into it.
Can anyone explain me the differences between above mentioned things. If i just root my phone without unlocking tje the bootloader then can i perform all root tasks? And also, can I flash.?
Or I should unlock Bootloader to flash..
If your device is rooted without unlocking the bootloader, you can do everything that needs root. You can install root apps and use them.
But you can't flash anything because that requires the bootloader to be unlocked. However, there are rarely cases which allows you to install custom software without unlocking the bootloader. Some devices also don't require to be unlocked to flash files, mainly Samsung and MTK devices.
If you have more questions or concerns about that, feel free to ask me and I will try to answer your questions.
So i cannot flash other roms without unlocking the bootloader..
But can i install marshmallow.?? I guess that too comes under flashing..
As I said in the title my device is G920FQ model. I want to try custom roms, is it already bootloader unlocked or is there a way to unlock bootloader? I've searched this place but couldn't find anything.
Also if it is bl unlocked can I just flash TWRP without rooting my device first?
EDIT: Got it all sorted out.
