[Q] About Bootloader…… - Xperia Z1 General

My device CDA is:1276-7948_R4B
But Bootloader is——unlock allowed:no
How can I unlock my C6903 Bootloader?

+1 same question

Your phone is probably carrier locked, if it is (e.g branded) then you will not be able to unlock the bootloader.

You cannot unlock your bootloader, it's locked by your carrier permanently. You still get root anyway.

You can't by any normal methods. Pretty much your only hope (and I wouldn't dream to propose this as some kind of guarantee) would be to remove the back cover and use the test point with SeTool as outlined in this thread.

Unlocked my phone with omnius

Im a little confused right now. I have unlocked my phone with omnius using 1 android unlock license and it accept any simcard, but does that mean I also unlocked my bootloader? Or do I have to follow the steps how to unlock bootloader?
Can I still update via pc companion?

Yes to both, you now have your bootloader unlocked and also you can use SEUS to update but really who want to use that crap from SE if we have flashtool?

You now have a sim-free phone that will accept any SIM card. I don't think you have an unlocked bootloader (I could be wrong?). To do that, you need to follow the instructions here.

People with bootloader unlock allowed:no [how to unlock it] (GSM ONLY NOT CDMA!!!)

Hi people I didn't know whether to post this in the android development forum so I posted it her.
Soooooooo.......... For people that are confused when they dial in *#*#7378423#*#* and they find out that it says boot loader unlock allowed:no.
I am just going to clarify a few things. Don't worry its not the end of the world you can still unlock your bootloader. thats the good news. The bad news is that it will require you to pay some money. You are probably having this problem because:
a) Your phone is sim locked
b) You are using the R800at or R800X if so then get out of this forum!!!!!!!!
So to solve this problem you will have to sim unlock your xperia play although, you MUST use a software that uses the phone's testpoint to sim unlock the phone e.g. Omnius any other unlocking method used that does not use the phone's testpoint will NOT work.
Once you have done that taaa daaaa!!!! now when you go into the service menu it should say bootloader unlock allowed.
Although your not done yet, now you will have to unlock your bootloader this is FREE to do in fact sony ericcson offers the instructions how to do it themselves. Here is the link to the instructions:
unlockbootloader.sonyericsson.com/instructions
Since i'm a new member xda not letting me put in any hyperlinked links.
Make sure you know the risks of unlocking it!!!!! Enjoy!!!!!!!!!
Last time i looked sim unlock does not unlock fastboot
No fastboot, no unlocked bootloader

No i'm just saying this because the requirements to unlock the bootloader on the se website says make sure it says boot loader unlock allowed: yes
I haven't tried using fastboot or anything this was just for people that were stuck here in unlocking their boot loader i was just sharing that it changes to yes when you take off the sim lock and i know it is possible to unlcok the bootloader of it even though it says its not the steps i have given does unlock the bootloader as i myself have tested it on my friend's o2 locked phone.
On my phone it says
Rooting Status:
Bootloader unlocked allowed: Yes
so do i have to pay money to unlock it or what?
I'd like to try and root it.
My phone was originally locked to O2, I got it sim unlocked from them and i still have bootloader unlock allowed:no ...
You have to do TEST POINT METHOD!
This Unlockes your Sim lock i think as well as fastboot which you need to unlock,
sim locked phones are branded and have Blocked Fastboot with a Unknown Patch the Bypass is test point method however you Must Not ever Update VIA PC companion or OTA Doing so = a brick.
If you want to pay up the money go to Aljendrissimo he has proven 12,000+ people with SE phones Bootloader Unlocked with OTA fix ans Pc companion which means you can have the ICS update but its got the sony suite

If it says bootloader unlock allowed:yes then you don't need to pay to unlock your bootloader just go to the link I put up and follow the instructions.
Also,on the other comments yes this does indeed has to be done through test point method which is very easy many sites do this, I used cellunlocker.net's se unlocking software to unlock mine. I also checked yes by doing the testpoint method it also,gives you the option to unlock the bootloader I do recommend omnius because you can by a android unlock liscense for just 10 pounds but to clarify you DO need your sim unlock to be done through test point so you can be able to unlock the bootloader

Please amend this in your first post as it is incorrect and very misleading to others.

What would be nice to know is how to unlock fastboot if your already sim unlocked.
I can understand paying for simunlock but paying for a fastboot unlock while i am already sim unlock would be double dipping.

Yeah I agree I think it possible and is something what the testpoint method does for us if someone could break down exacty what it does I think the developers might be able to find something

It has been broken down for you on the first page, if you do use the test point method then you can't do OTA updates which means, you can't officially update your play when offical updates come out but it's not all bad as you will be able to flash the offical update with a FTF with the flash tool. It is recommended to use the test point method.

No I don't think that is true because you cannot do OTA updates only if you have a locked boot loader i'm not sure where you got your info from mate but i'm pretty sure all the test point method does is sim unlock your phone and does something to make the bootloader unlock possible and that is what I m trying to find out- what it does to make the bootloader show yes .
I have confirmed with various trusted sources if you are still able to update even if you are sim unlocked with test point and they are saying yeah only if you haven't unlocked the bootloader.

So ... there is any results?
So, no chance to unlock bootloader without testpoint, right?
My R800a is not sim lock, I can use it with any GSM sim but the status still says bootloader unlock allowed:no. How can I unlock bootloader ?

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.

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.

Bootloader unlocking

What, precisely, must be done to unlock the bootloader for an SM-G900A or SM-G900T? Must something cryptographically be broken? If I get root access through towelroot, will that help? Are the people at the AT&T store capable of doing this bootloader unlock if pursuaded to do so?
No they will definitely not help you unlock the bootloader lol. AT&T locked it down themselves, and no one has found a way to unlock it yet. All we can do is wait for someone to figure it out.

Can you show what is your Bootloader version?
Just an FYI, 900A is ATT with locked bootloader, the 900T is T-mobile which already has an unlocked bootloader. Just buy a 900T unlock the Sim and put in an ATT Sim. That's what I did. No worries about locked bootloader!

I think a read something about Safestrap being able to unlock S5 locked bootloaders, here for example. Not sure if this works though, have not tested it myself.

Man there is no way (till now) to root Z5 without unlocking bootloader infact all newer phones require unlocking bootloader.
But you can always save the drm keys with amazing tools available for future use.
