Hi all, mi question is simple, and I think if the fastboot is only in unlocked devices, or in all?
If I enter in this mode can I flash a kernel or room if I have locked boatloader?
Thanks
You can flash it, you can flash a kernel with flashtool, but it won't boot with locked bootloaders. That's the problem. We can flash anything we want, but getting it to boot is another issue.
Thanks, solved

Can't boot the phone neither becase there is no OS, can't boot to recovery mode only fastboot mode.
I used the oneplus one toolkit to install the CM11S, would not let me do it . and accidentally I lock it again with toolbox. the problem comes that I can't unlock the bootloader anyway for somehow.
Pls help. my phone just stuck on the fastboot or 1+ booting. can't flash the img because it's locked!!!

You can't. The bootloader has to be unlocked to change recoveries.
This is why you don't use toolkits, you do things without thinking and then are unable to get yourself out of sticky situations.
NEVER relock bootloader without custom recovery installed AND rooted OS running!
if you do, you're unable to change tamper bit to unlock bootloader again.
that's why i never relock my bootloader! just to be safe.

i want boot repair file
Can you boot into flash mode or fastboot?
i have same problem i flashed cwm zip through twrp then booted into cwm and done all wipes ie system,data,cache,davlik and then phone went off now nothing att all happens not even charging?
It won't boot if you've wiped the system and data in recovery there's nothing left to boot up you'll need to flash ftf via flashtool and start from the beginning
I've got the same problem, i built AOSP 5.1 and flashed it via fastboot (boot.img, system.img & userdata.img) and now the screen doesn't power on (bootloader is unlocked). I also can't get into fastboot/recovery. What should i do now?
This is the first time i'm trying to put a custom ROM on a sony device.
Thanks in advance!

Did you update your bootloader? before flashing the custom rom.

Update the bootloader?
I did it the same way i did it on my oneplus one, which is just oem unlock.
On oneplus one this updating isn't needed, how do i do it?
A Xperia isn't a opo, it's sonys recovery partition you'll need to flash the updated bootloader through Emma sonys version of flashtool for unlocked bootloader devices
Hey guys, i have a problem, my Bootloader is locked and i can't access my recovery, and there is no rom installed, what should i do now? i can't access Developer options to Allow OEM unlock because there is no OS.
am i screwed? or there is something i can do?

Did you ever enable developer options and allow USB debugging? If so, and you can connect to ADB on a PC, you can flash stock firmware back onto the phone.
or try this:
As I didn't have USB debugging enabled I couldn't connect to the phone via ADB, but if you put it into recovery mode you can use Fastboot. Hold down the power key to turn the device off and turn it on while holding down Vol Down to load up recovery mode.

However, with locked bootloader there is no room for error in flashing firmware via ADB or you will brick the phone. You have to flash the correct firmware exactly for your phone, with the same level of bootloader you already have or newer. You can't flash Mexico over Brazil or Lollipop over Marshmallow. Has to be exactly what was made for your phone, either what you already had or newer (if it exists).
What OS was installed before?
But WHY is there no ROM installed? What did you do?
The OS installed before was the most recent Stock MM Brazil, i installed the stock rom, it worked, then i wanted to go back to stock recovery, it it worked too, then i wanted to locked my bootloader, i locked, after that i couldn't enter recovery, neither boot to OS.

You wanted to re-lock your bootloader? Unlocked bootloader = God mode.
Did you ever have TWRP? You said you wanted to go back to "stock recovery" (not sure why, it's mostly useless compared to TWRP custom recovery.)
I'm not sure why re-locking the bootloader would wipe the OS...
But you can boot to the bootloader screen using the volume and power button and re-flash the stock firmware, using ADB. Here's the link to the newest Brazil Marshmallow for XT1225:
http://ftpeil.eil.com.br/vip/motoro...S24.107-70.2-7_cid12_subsidy-DEFAULT_CFC.xml/
This guy below got out of a jam because he had an unlocked bootloader, which is very forgiving. Locked bootloader is harder.

Yeah, i don't know what happened either, why the **** did my OS got Wiped?
Can i flash the stock rom with the bootloader locked via ADB? how?

You have to boot to the bootloader screen manually, using the volume + power button trick.
Once on the bootloader screen, when you plug you phone into a PC with ADB installed, it should recognize it.
Then, flash the full stock firmware, from the link above. It's Brazil Marshmallow firmware with December 2016 Security Update. I don't know of any newer right now. You have Brazil XT1225, so that Brazil firmware is compatible with your phone.
But with locked bootloader you have to flash exact same version or newer made for your phone, and you have to enter the commands correctly or you may brick your phone. (When I flashed from Puerto Rico Kitkat to India Lollipop, I messed up. But since my bootloader was unlocked, I just reflashed again, when I realized my mistake.)
If you are not sure of the steps, google Motorola firmware ADB. Here's a couple of excellent tutorials:
How to Manually Official Firmware on any Motorola Device
https://forum.xda-developers.com/dr...force-how-to-manually-flash-official-t3282077
I use this one above. IGNORE where it says you need an unlocked bootloader, because he's talking about cross-region flashing which you are NOT doing. You are flashing your own region firmware.
This one below is by rootjunky and he while he also discusses RSDLite, later in the article he says ADB/fastboot are best as RSDLite can stall.
Motorola Firmware Restore Plus Unbrick
http://www.rootjunky.com/motorola-firmware-restore/
If you get your phone running again, I suggest you unlock the bootloader. There are ways to hide an unlocked bootloader (like Magisk), if that's why you locked it back... But an unlocked bootloader + root makes it YOUR phone and much easier to recover from disasters.
Thanks a lot Chazz, it worked, thanks for the help, really appreciate it, thanks for all the useful tips too.
Just as the title says...
I have Xperia Z5 SOV32
It has Bootloader Unlock Allowed: NO, but somehow I can go into fastboot mode
Some people said that they cannot get into fastboot mode since they can't unlock their bootloader
If I continued to flash a stock (or a region customized stock) FTF, will it brick the device?
Thanks!
No, its normal. You can always boot into fastboot, even if you cant unlock it. Stock rom is always flashed over flashmode so you can flash whatever you want
Thanks, just to make sure first before doing anything to it, and indeed it works flawlessly
So, i recently flashed arrow os 12.1 on my poco x4 pro (veux) using twrp. Flashing the rom removed twrp and now i cant flash it back because fastboot says that my bootloader is locked...
Of course, it isn't and the problem is that allow oem unlocking isn't on... I really would appreciate some help because i've been stuck on this rom for a day.
Gonna wait for some answers, thank you.
In the first place, flashing the rom shouldn't relock your bootloader. Can you please reboot to fastboot mode and use mi unlock tool with the same account you used to unlock bootloader first time.

Thank you for your response. Sadly i already tried that and the tool says that the phone is unlocked.
I'm trying to reflash stock rom via EDL mode, but i always get some error.
By the way, when using fastboot getvar command, it says that my bootloader is locked.
So, i recently bought a poco x4 pro (veux) and flashed a custom rom using twrp. Sadly, the rom's recovery managed to overwrite twrp and when i tried to flash twrp back, i could not flash it because fastboot said my bootloader wasn't unlocked. When i tried to unlock the phone again the xiaomi tool said that the bootloader was already unlocked. So, i used the getvar command which said that my bootloader was locked. So, i remembered that i didnt turn on allow oem unlocking in developer options. Sadly, when i looked for it the setting wasn't there. I tried using Edl mode to go back to stock but with no success. I always get some failed to read hello packet error. Can someone give me any help? Im kinda getting desperate...

Go to service centre if it is critical. I have never seen such case so i couldn't help. I am afraid that you would have to pay the service centre people money for reflashing your device.
Also have you tried flashing fastboot ROM (MIUI) through fastboot? Also try to flash stock recovery rom via the recovery you have now currently.
Another thing you could try is using the Xiaomi official flashing utility (which is not unlock tool) to flash stock rom which does not require OEM unlock.
