[Q] Unlock Bootloader Xperia z1 14.2.A.1.136 - Xperia Z1 Q&A, Help & Troubleshooting

Hi, I have an Xperia Z1 (C6902) recently bought and have already updated to version 14.2.A.1.136 without unlocking the bootloader, I need to know if it is possible to unlock this version.
I am new to the forum and I have not much experience, anyone can help me?

Type *#*#7378423#*#* on phone keyboard and see what Bootloader Unlock Allowed saying, Yes or No, if Yes it can be unlocked, if No it cannot be unlocked and there is no way around. Bootloader have nothing to do with SIM Lock.

I tried unlocking bootloader thrue fastboot, getvar version etc says 0.5. But the commando with unlock key says failed and second attempt "you already rooted " that's impossible, I can't be. . Anyway I Have flashed ftf 290 with flashtool and then updated to 136 thrue Sony company software.
What's wrong? Any tips?
If i try unlock thrue flashtool it says done. And then I tried flashing doomkernel with success. However the phone didn't almost boot and when it does I have strange vibration false and random reboots.
I'm back to stock for now and would like to unlock so I can root

Is possible to unlock the bootloader without downgrading to 14.2.A.0.290?

I tried to check if it is possible, the procedures did with the code * # * # 7378423 # * # * and I see: Bootloader unlock allowed: yes
What I need is to know if you could help me with a tutorial to unlock the bootloader downgrade by doing an easy means as Fastboot.
Forgiveness for the mistakes, I'm trying to translate everything, I speak Spanish only.

What do you try to do exactly? Unlock SIM Carrier or Unlock Bootloader?

If Bootloader Unlock Allowed saying Yes that mean it can be unlocked. Unlock bootloader will not unlock SIM Carrier.
The instruction to unlock bootloader are HERE on official site for Z1. The latest firmware is .136 so do not worry if there is saying .290.

You don't have to Unlock Bootloader to get Root, you can Root your phone with Locked Bootloader.
Follow instruction from HERE, watch the video Tutorial by Shem, then follow the instruction HERE for .136

Thank you very much, that good you do not need to unlock bootloader, is that everywhere you look as I was saying root access needed to unlock the bootloader. What I really needed was to have root access!

Can not solve 'no service ' problem

Hey there!
after an unsuccessful try to unlock my bootloader (11w42) my phone is still working, but radio function is disabled.
I can only enter my PIN number...
Is there any way to get it back working again? I already tried repairing with SUS and flashing the firmware with flashtool, but still there is no service.
Some wrote to get back radio function with msm7227_setool2, but i guess thats only for already unlocked bootloaders, right?
Thank you so much for your help!
i think that is related to the "baseband" check the version of your phone maybe you are using the wrong one
Type this using dial pad *#*#4636#*#* go to phone information and check if ur radio is off....
Sent from my E15i using xda app-developers app
I am running on the 015 baseband. Maybe i should flash the baseband itself again.
Typing in the mentioned Code Resultate in nothing. The field gets cleared After the last *
Ill let you know if i found a solution.
Thanks a Lot btw!

Some said unlocking bootloader may sim lock your phone. I think you need to re-unlock it.
---------- Post added at 09:23 PM ---------- Previous post was at 09:22 PM ----------
by the way, how did you do that? and congrats for you! I'm locked bootloader. It's a great news that you can unlock your bootloader without
hard bricking.
1 more time
flash the stock Firmware download from my signature
flash the kernel with SIM card inside your phone during flashing

As I said: 'unsuccessfull'!
The phone was a gift from one of my friends, he did not read the warnings about the production date but tried unlocking
So now radio is off...
I'll flash 2.1 and baseband later to check if that works
I think it's sim lock but I'm not sure :/ :/

Z1 custom bootloader for recovery.

Hello,
Has anyone tried this yet? http://developer.sonymobile.com/201...for-a-range-of-unlocked-xperia-devices-video/
It doesn't seem to be working for me!:
Steps taken:
Flashed stock 5.0.2 using Emma
Flashed TA Updated using Emma
Pressed volume down + power until vibration occurs
release power button
result:
Phone shows sony logo and not dead android (stock recovery) and then just reboots
Yes, I'm facing this behaviour too... It seems to be a known problem for some users, as it has also been postet under the original Sony article on deloper world... Hope Sony recognizes the problem soon and fixes the bootloader
Same here. Nothing happen.
Sent from my C6903 using XDA Free mobile app
Could one of you upload the ftf file so that non stock users can flash without wiping and flashing and all that...? Thank you

Could it be that you have got a sim locked phone? I a not sure but most sim locked phones have got a unlockable bootloader.
There are Z1s with:
Bootloader Unlock Allowed: Yes, and
Bootloader Unlock Allowed: No
It doesn't matter if you are SIM locked or not. SIM locked means you are tied to one specific Carrier and cannot use other Carrier's SIM. If you insert another Carrier's SIM it will not be recognized by the phone. You can have the phone "unlocked" meaning it will allow you so use any Carrier SIM you want to use but that doesn't you you have unlocked your bootloader.
If your phone says [Bootloader Unlock Allowed: Yes], you can unlock it using Flashtool or go to Sony's website.
If your phone says [Bootloader Unlock Allowed: No], sorry mate - you don't have any way of unlocking your bootloader.

That's the reality.
As already said only phones with 'bootloader unlock Allowed: yes' can be unlocked.
If this is my phone I would be interested in knowing why my bootloader isn't unlockable and I would write to Sony.

None that I know of personally. I did a Google search - I found a youtube video but I doubt it's credibility. But I am not an Advanced Developer or anything like that. I'm just another guy with an Android phone. And from what I've read so far, if your phone says [Bootloader Unlock Allowed: No] that means:
"No.",
"Sorry but No!",
"Nooooo-Waaaayyy",
"uh-uh!", "Sorry, nope!",
"No can do.", "Nada!",
"Let me thing about it.... I say... No!"
"Hmmm.... nah!"
If your phone was purchased as a 2nd hand phone, the original owner must have purchased it as a SIM-locked phone and have later had it Open-lined so he/she can use any Carrier SIM he/she wants. But as I have mentioned before; which almost everybody gets confused about; if you have had your phone Open-lined it doesn't mean you have unlocked the bootloader as well.

[Q]Stuff to do before unlocking bootloader/root

So I just got My OnePlus 3T and like most, would like it rooted! I have had experience with rooting and unlocking bootloader, but since My earlier devices were by Sony, there is a lot of difference. In Sony devices, there was no need to unlock bootloader to root, but it seems that for rooting 3T, I need to unlock bootloader. Even that doesn't seem difficult since there is this great guide with a toolkit. But My concern is that do I need to backup any partition before I unlock bootloader? Like in Sony we had a TA partition, which could be backed up before unlocking bootloader and would get wiped after unlocking bootloader. This is just for keeping it as backup and restore it to device if I decide to lock bootloader again. Also, will I loose anything if I unlock bootloader? Such as anything specific to OEM or camera functionality?
Nope. On OP devices there's no permanent penalty for unlocking. If you ever want to go back, you can re-lock the bootloader. But: unlocking and locking will wipe your phone. So you can't carry over root to a locked bootloader.

Okay, that helps! So to return back to locked bootloader everything would need to be like stock(no root, custom recovery etc.)
I had read somewhere about EFS backup and that it is related to IMEI number of the phone. This need to be done before or after the rooting process?
Also, would I need to disable encryption (as it is seen enabled in settings) and remove the fingerprint lock option before unlocking bootloader?
And just to be clear, I'm going to do following steps in the sequence to flash TWRP and root, Please let Me know if it is correct:
1. Unlock bootloader
2. Flash TWRP.
3. Flash SuperUser
all this with the help of ToolKit of OnePlus 3T. I don't need to take backup as the phone is new.
Also, I will be flashing the phh SuperUser for support with Magisk as mentioned here.
Hey, do you guys know if you can get official OTAs if you have TWRP installed?
Former Z2 user here @Mirhawk
I did the advice backup as a precaution. Then did your 1,2,3 steps. May I ask, why Magisk? Is Android Pay currently working with stock ROM + Root + unlocked bootloader?

I'm not interested in Android Pay, as it doesn't work in My country, It is Pokemon Go I wanted, but I guess it doesn't work. Thanks for the infor though! It was a lot simple in Sony!

Xposed with locked bootloader possible ?

No, because you need root to use Xposed wich requires TWRP ergo an unlocked bootloader.

Yes but how are you going to flash it? With stock recovery its not possible. Btw locking a bootloader when you plan to root or use mods is NEVER a good idea, besides that in the case of OnePlus it doesn`t void warranty so it would be unwise to not unlock or relock the bootloader.
If your device gets bricked while your bootloader is locked, you're going to get screwed. The most you can hope for is a complete phone reformat through one of the unbrick guides
Can't we flash bootloader from fastboot or recovery in op3?

Flashing Custom Rom on Canadian Variant of S9

can you flash custom ROM on galaxy s9 Canadian variant?
Model: SM-G960W.
I don't have OEM unlocking option in my developer settings but when I connect my phone to ODIN it detects it and says added.
Boot into odin and look for "Activation Lock OFF" if it says that, you probably can

Please don't answer a post if you don't know the correct information. These devices have permanently locked bootloader and cannot be flashed. All you did is cause confusion
2 years late but it sucks than I can't modify this phone due to bootloader locked
