I've seen the new FlashFire app and I've seen in the disclaimer that you need an unlocked bootloader in order to fully use it.
On its thread they also say that it would work and unlocked bootloader is needed for things like flashing kernel and so on, but also for some things you could soft brick and it's device dependant.
Has anyone tried FlashFire with locked BL?
Is it safe to perform just flash some little things and backups?
Edit:
No, it does not work
i flash mods on my locked bootloader every time. no bio hazard done. Never faced any kind of boot issue (Just Don't flash that XtremeMusic MOD on locked bootloader, Just Flash Viper, Dolby and Walkman). Flashed a custom rom made by myself without any issue.(issue was in the ROM, it booted fine already, but certain force closes occurred). Well, it has a bug restoring backups, that will cause you to soft brick.

Does unlocking the bootloader give you root?
And in which instances can you flash a custom recovery or customs ROMs?
Rooting means you can install apps that require root access (like titanium backup or setcpu). Unlocked bootloader means you can load any rom, kernel, etc that you like. Unlocked bootloader is usually acquired after rooting.
I'm not sure I totally understand the first reply, so here is my take on it.
Rooting will let you install apps that require root as already stated, but rooting will let you install custom ROMs and do just about any tweak you want. I finally did unlock my bootloader, but the only benefit I gained was being able to change the flash screen, which is the first screen you see when the phone powers on.
I have read that it's harder to brick your phone with a s=off bootloader too.
It is not harder to brick your phone with an unlocked bootloader, just easier to recover from a soft-brick. An unlocked bootloader will allow you to flash using fastboot. So in the case of a corrupt recovery, or something along those lines, you are able to flash it using your computer. It basically allows you to flash different parts of an image separately.

That's pretty much what I meant, I just didn't say it right. Thanks for clearing it up.
How to find my phones' bootloader is locked or not? Because i already flashed different custom ROMs and using it.

If you are rooted with a custom recovery, your bootloader is unlocked.

Thanks buddy,
I want to know that what if i flash ROM for locked bootloaders?
Honestly, I didn't know you can root your phone till today I read a few posts here. So thank you all guys for the input
slight confusion over rooted
i had the .67 generic uk firmware, i downloaded the central europe .73 firmware and used flashtool to flash the ftf file,
all worked fine once i installed the drivers on flash tool,
my confusion is...... alot of people are saying there phone is rooted/bootloader unlocked, am i rite in thinking my phone is rooted and not unlocked,
others have also said they have flashed the .img to the phone which i havent done, is there something ive done wrong ?
Hi, I have already rooted and unlocked my bootloader then proceeded to flash a custom ROM. I want to try out a different ROM so do I have to re-do the whole root and unlock bootloader process ? I know its just flash one simple zip file in recovery but the reason I ask is my phone got soft bricked last time around.

Once it's unlocked you don't need to do it again unless you intentionally re-lock it or get a new phone.
Also be careful if you somehow get vzw OTA pushed to your phone (sometimes happens without you knowing it) it will lock your bootloader again and when you go to flash it will say something about taking your phone to verizon. Don't panic as most people do all you have to do is unlock again and everything will be fine
Hello,
I'm trying to install TWRP on my wife's TFT300T. Its lagging and freezing bloat apps hasn't helped. It's rooted stock 4.2 with a locked boot.
I rooted it with motochopper, and tried installing the latest 4.2 (2.6) with the terminal method and it didn't seem to work. I get an error when trying to access the recovery menu. I tried using adb/sdk, but I don't see the usb option fro fastboot.
I have the latest unlock tool from asus, but I want to be sure I need to unlock the bootloader. I have everything backed up with titanium, but I'd like to get a recovery of the stock too if possible.
If someone could confirm I need to unlock the bootloader that'd be great. It hasn't specially said that I need to unlock the bootloader in any of the 5 or 6 topics I've read. Thanks!

To my knowledge and for a bit of backround the reason the tf300t needs to be unlocked to install twrp is any kernel package you flash needs to be cryptographically signed, the key for this has not and wont be released by Asus, meaning if you try flash twrp without being unlocked, the bootloader looks for a signature on said package but doesn't find one so its not accepted, unlocking the bootloader disables these checks so we can flash what we want.
Short answer
Yes you need to have an unlocked bootloader to flash unsigned kernels
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
So I've been looking into this, it seems it's possible to use flashify which allows you to flash .img files if your bootloader is locked and you have root you can flash twrp this way. Flashify can also make backup of stock recovery and install it, the reason i'm interested in this is security, as unlocked bootloaders have lots of risks.
Another post i was reading a person suggested, different manufacturers have different ways they implement locked bootloaders so some phones recovery might be protected and can't flash twrp while locked others may differ, I'm not sure. I currently have a Samsung S7 Edge, some people suggested issues around possible hard bricks, suggesting it's more likely to happen with a locked bootloader, then others saying fastboot wouldn't be able to recovery the device if installing a rom failed.
Someone pointed this out about my OEM unlock not been able to enable it to recover, tho odin doesn't require that to be turned on to flash back the stock firmware from download mode so that should fix that. I want to know the risks involved if flashify flashing twrp, kernels and roms while bootloader is locked is likely to work fine, i have seen posts of people who have done it most the comments seem like they could be assumptions best guesses around this type of thing. I can't find much on it.
What i'm thinking is find an exploit to get root, while locked flash twrp with flashify use twrp to flash xposed maybe? then restore stock recovery after flashing all the things i need, so if i loose the phone bootloader is locked and they don't have clear access to twrp, i think magisk is impossible as that modifys the boot which is the locked bootloader i believe so don't know which things magisk or others will or won't work.
Appreciate all reply's.
Thanks.
