locked and unlocked bootloader

I wanna share my experience with my locked bootloader.
I tried once to unlock and install a "just 4 unlocked" rom (2 roms actually) but the radio system didn't work (no phone, no wifi, no gps).
I got back by flashtools, i installed a rom 4 locked rom and i tried once more to unlock the BL. I installed CM10.1 and now everything is working perfect!!!
I got just a question 4 you: why does some xperia z has the BL locked while others unlocked?

All Xperia Zs come locked from the factory. Most can be unlocked to flash custom roms. Some are permanently locked because their carriers are iffy (to put it nicely), but those are the minority.

Keep Questions in the Q/A section, not in General.
And No SONY device comes with locked Bootloader always. All are locked by default from the factory. Among which some can be unlocked and some can not because the Carrier.

Ok, but my gadget showed "no in Service info > Configuration > Rooting Status > Bootloader unlock allowed (and in the post about unlock BL they says that if it's "no" the device cannot be unlocked).
Thank you
PS: How can i move the 3d to Q/A ?

That is what I said.
All the Devices are locked bootloader by default.
Bootloader unlock allowed= Yes -- This means you can unlock the bootloader by following regular method.
Bootloader unlock allowed= NO -- This means you can not unlock the bootloader. Because of the Carrier issue i believe.

thx i got it.
But mine showed Bootloader unlock allowed= NO but i was able to unlock it after 2 try. I think every one following my procedure might do it.

I think you will always have been able to unlock yours, you just didn't do it right the first time.

So are you saying you have a locked boatloader and can install. CM10????

did you root it and put a different ROM on there? the status might change say no but you can still unlock it. Simply put if first time you boot up your phone and it say Unlock bootloader = NO, then dont try to unlock it. When you root and flash a different rom that status might change to yes but in reality it still a NO

Eventually a right answer.
I was told the same. But i love to risk "playing" with my gadgets. So when i bought the xperia z through a carrier I saw the first time i boot up that the phone Unlock bootloader = NO (about 5 minutes after i bought it from the shop, so it was "original as the carrier made it).
I didn't care it and i tried to unlock. I installed a unlocked bootloader and rom and i had all that problems with the radio stuff . But the second time, after i recovered it by flashtool and a sw from sony (i don't remember the name) I was allowed to unlock it and install unlocked stuff. Now I am with Paranoid and I am so happy

same here... unlock it. install all the unlocked stuff. Radio might don't work. . Get ur phone back by flashtool and sony sw (i don't rememmber the name). The sony software will say u after a while u r not able to recover the phone cuz you are using some some software that is not sony. Don't worry and install another time a rom unbranded by flashtool.
now unlock the phone again and install everything u might like
There is only a problem with the twrp recovery, so use only the other one

Can anyone else confirm this?
Thanks!

Very interesting... Im waiting the confirmation from sony to pick up my phone without cost to change the fastboot to yes, but if this is true and someone else could confirm this method il do it tonight!!!!

I think if you want others to try what you've done, (and it is interesting if we can unlock bootloaders this way)
then you may want to highlight which steps you did in more detail.
Which roms did you try to flash that resorted in no radio functions?
which rom did you try to flash with flashtool? which version of flashtool as well?
Did you do anything else?

I somehow doubt engineers would make an oversight as big as this one.
But fingers crossed nevertheless.

+1 for a detailed description of the steps you took. This could be huge!

Indeed, this move would make the XZ much more attractive for buyers which have the bootloader locked from the carrier.

Relock the bootloader

ok i know there are some tutorials here but i want to share my guide
this is a guide wich explains how to lock the bootloader
ok with these u will lose all ur data or apps so please make a backup first
the status code will not return to 0 but to 2 (i have no solution for this -if someone could help me)
1 first go here and download ur firmware
http://sbf.droid-developers.org/phone.php?device=14
2 extract the firmware on desktop or where u want and rename to X or how u want.
3 after u extract go into the folder and search for Windows folder.Copy the 3 files on X folder
4 download these files
http://www32.zippyshare.com/v/60108039/file.html
extract and copy the files in X folder
delete flashall.bat from X folder if u have one if not don t do nothing
5 put ur phone in fastboot .Power off ur phone.Then power on and volume down together.after 3-5 seconds let the power button.
u will be in bootloader mode
6 go in ur X folder and double click on Flash Moto G.bat
7 if Windows 8 request ur admin privilege just say ok
9 wait
10 when all finish the phone will reboot
wait untill the phones is on.Power off again and put one more time in fastboot mode.Then with power button just click on Normal Power up and it will flash ur logo for removing the bootloader warning
11 done ur bootloader is locked
for me works let me know if works for u
thanks to toco93 for help

And if I want to upgrade my Android Version, can I just flash the firmware in a recovery?
Or do I need to extract it and
fastboot flash bootloader bootloader.img
etc.
EDIT: Thank you !
Worked for me.

Doing this we recover again our warranty?
Thanks!!

Technicaly (for Motorola) you can`t restore warranty after requesting a unlock_code and unlocking your bootloader with it. They may still deny warranty even if you relocked the bootloader.

Requesting the unlock code does not mean you will use it. Obly way to prove that is by the unlocked message screen

Is it clear now?

The question is... Is possible for Motorola to know that you have unlocked the BL if it is locked when phone goes to warranty?
You can have requested an unlock code, and haven't used it...

True but i think once you unlock your device using the unlocked BL code it stays in their database so they should be able to tell if your phone has been unlocked or not.

When is my warranty voided?
Your device warranty will be voided as soon as an unlock code has been generated through our online tool, regardless of whether you actually unlock your device.
Please do not request a bootloader unlock code unless you have read and accepted the terms of our legal agreement.

Wrong. Warranty void is still to No. Specially in EU, impossible to void warranty only for asking that code. If you don't use it the bl is still the same. No change on it. No warning message. No fuse burned. Come on...

Agree, silly and illegal, but if Motorola deny my warranty what can i do? Go to a court?

The problem is "transitive property" or "consecutio temporum".
The OFFICIAL thinking motorola about this: IF i ask the code, AUTOMATICALLY then i will unlock the bl. OFFICIALLY IS THIS, because they don not cover the other "street":
IF i ask the code, I asked simply a code. STOP. No other. There is not a "transitive property" for that if i ask a code then bl unlocked. Only this last exists for Motorola, and it's right in this sense, it's logic.
But the real life is different: IF i ask the code, I asked simply a code. STOP. So It's impossible that warranty can be void from them only for "asking the code". There is no change on phone and so on... In EU especially.

I have actually no problem with that what you are saying. I see it in a similar way. But logic and law is sometimes not very close to each other. I don't wanna go toooo off topic but how is it with computer games? You can buy a Game but it is not yours. You have often only the license to use it. This is also somehow strange and does not fit in my logic.
I understand that in the EU we have a big benefit because of our law to these things but are you a lawyer and can you be so sure about that what you are saying? Especially for the rest of the world? Have you read the complete license agreement? Sure, maybe the license agreement is futile........i hope so I'm not worried in any way......but just my 5 cents.

Hi there,
I want to lock my bootloader. I followed your guide and other guides too but when cmd comes to the step : " fastboot oem lock " It gives me the error : "(bootloader) sst lock failure!
OKAY [ 0.047s]
finished. total time: 0.048s "
And my Status Code is still 3. Does somebody knows why I get this error ? As I already said this is not the first method I tried but all failed.
Thanks.

So if I root it I will lose the warranty ? You sure ?

Yes you loose warranty. If you unroot it, you will have your warranty back.
To unroot, you must reflash the original software.
Unlocking bootloader won't affect warranty.

In my country, if you unlock your bootloader, it won't affect warranty...because the people at the service unlock your bootloader so they can fix the stuff that you encounter.

when i asked for bootloader code, there was some mesaage with, "unlocking will void warant" .. and jeah, they can see, if you are requested bootloader code.. and jeah, waranty are lost if you change software as it wasnt intend. but flashing stock room will lock bootloader and will unroot phone, so warranty need to be back, but thats only theory. better dont try things with phone, if dont know what you are doing!

If you unlock the bootloader, you can easily root your phone. Did they install TWRP/CWM or any other custom recovery? Can you check it?

Question about Official UL Bootloader.

I unlocked my bootloader, officially. And basically, I got scared when I have read from somewhere that my warranty is void and I will not receive any FOTA. Is it true? Can I relock it officially? Help.

You can relock but you already lost your warranty

oh fckk. I'll just put in my mind that warranty is nothing lol. But if I relock, will it wipe all of my data?

If you relock, can they detect that it's been unlocked?
And what if you use a non-official unlock tool?

If you unlock officially, your phone will be registered in their system as unlocked device. So they won't track your device status anymore. They won't know if you relocked your device or not (since there's no official relock method).
If you unlock unofficially, then won't know your device is unlocked in the first place. So you can relock and claim warranty anytime.

Thanks for the clarification!

Then I presume you need an internet connection to perform the official unlock (otherwise they wouldn't get notified). What if you unlock while being totally offline?

Nothing is 100% safe. Anything could go wrong anytime. But most people unlocked by the unofficial way without any problem (I did too). So I'd say it's very safe.

Nokia TA-1083 (6.1 plus) free bootloader unlock

Hello,
so I have been looking for a free method to unlock the bootloader on this nokia. In the developer section there is a greyed out "unlock bootloader" option, but can't press it to work. I have registered in official HMD site and also downloaded and installed the application. It sayd that it does not work. So could please anyone tell me how to unlock the BL for free? I have been looking around for long and found some pages but those seems to be a scam.
Greetings.

There's no way to unlock the bootloader on Nokia phones for free, the only way is a paid service.

Yes you'll need to unlock bootloader to do any sort of modification to system or even flash a stock rom by yourself there's no recovery tool nothing.
You should contact @singhnsk for paid unlocks. Frankly any tutorial you'll find on the internet is fake or old those worked on Android 8 and that also you'd need unlock keys which you'll have to buy.
