Hi all,

Still new on Xperia, so don´t "kill" me yet.

I also have bootloader unlock NO, been reading a lot and i need to ask, does it has something to do with fastboot ability, because when i put the phone in fastboot mode, i can use flashtool (fastboot mode) i guess someone has already tried it, but....

Thanks
[Xperia Z1 Android Development] -Happy Feet-:
Hi, when it sayed : "Bootloader unlock allowed: no" there is no way to unlock the bootloader.

[Xperia Z1 Android Development] pemith:
same problem here.....couldn't unlock once again :confused:
[Xperia Z1 Android Development] mirhl:
"device is already rooted" means

nothing

.

It always comes out in flashtool.. so anything else could be more helpful
[Xperia Z1 Android Development] pemith:
so that means i won't be able to unlock my Z1 bootloader once again?
[Xperia Z1 Android Development] mirhl:
Does this help?
[Xperia Z1 Android Development] pemith:
yeah....finally it's worked. thank you master :victory:
[Xperia Z1 Android Development] dedei:
If I re-unlock my bootloader using Flashtool, will it wipe the phone again?
[Xperia Z1 Android Development] mirhl:
Yes

But you could even flash your unlocked TA partition (if you back-upped it) and nothing will be wiped
[Xperia Z1 Android Development] dedei:
What?

If I create a backup on recovery now, unlock my bootloader and flash a custom kernel, can I restore the previous backup? Is that what you meant?
[Xperia Z1 Android Development] mirhl:
No.

I was telling you the only method to re-unlock your bootloader which wouldn't wipe your data partition

TA partition is that special partition of the phone which stores your unique IMEI and the bl unlock status
[Xperia Z1 Android Development] dedei:
oh I know, as I had previously unlocked my bootloader and relocked it using my TA backup.

BUT if I do a nandroid backup now and unlock my bootloader, will I be able to restore the backup while maintaining the bootloader status?

I think so but it's always nice to have more opinions ha
[Xperia Z1 Android Development] gregbradley:
It will be fine.

Nandroid backups will not effect the bootloader status.

If you are unlocked then you can restore a backup of a locked bootloader.

If you are locked you will get a bootloop if you restore a backup with a custom kernel
[Xperia Z1 Android Development] dedei:
ooo thanks. Will try this now!

---------- Post added at 02:41 PM ---------- Previous post was at 01:55 PM ----------

Everything went well...rebooted and bootloop. Flashed other kernels but it's always stuck at bootloop and can't mount data :crying: :crying: :crying:
[Xperia Z1 Android Development] gregbradley:
What exactly did you do?
[Xperia Z1 Android Development] dedei:
I just unlocked my bootloader using flashtool.

After a lot of trial and error, I managed to flash a .757 FTF, which relocked my bootloader (???????? lmao)

Then I flashed doomkernel and now I'm restoring my nandroid backup. Let's see how it goes :silly:
[Xperia Z1 Android Development] gregbradley:
This is impossible

OK
[Xperia Z1 Android Development] dedei:
I know! After flashing the .757 ftf, I went to service menu and it said Bootloader unlock allwed: yes. I guess flashtool didn't unlock my bootloader properly.

---------- Post added at 03:52 PM ---------- Previous post was at 03:25 PM ----------

It's alive! Oh god that was terrible lol.
[Xperia Z1 Android Development] exist2resist:
Is there absolutely no way to unlock the bootloader if the service menu says "No"?

Is there no hardware mod I can do?

I really want custom roms on my phone, already rooted and backed up TA partition.
[Xperia Z1 Android Development] mirhl:
There' really no way
[Xperia Z1 Android Development] exist2resist:
Ahh fiddle sticks, guess I'll upgrade to the Nexus X and give this to the GF.
[Xperia Z1 Android Development] dedei:
I think I found the reason why I got a bootloop everytime I tried to unlock my bootloader:

I was running the advanced xperia framework before unlocking it, and as it wipes the data, they conflict and you end in a bootloop! So my advice to anyone trying to unlock theirs, don't do it while running the advanced framework!
[Xperia Z1 Android Development] ja1378:
i do tut in op but i have recieve "command didnt succeed"help pls
[Xperia Z1 Android Development] ehbm:
I want to unlock the bootloader, my phone is with root and installed in accordance with the Recovery tip of you, wanted to know if I can back up the device via recovery before losing all doing with the procedure of unlocking bootloader and then restore that backup without problems? That does not work because the backup was done with locked bootloader?

Sorry for my bad english =p
[Xperia Z1 Android Development] gregbradley:
Yes you can do that, but its easier to use Titanium to backup your apps

Then backup your internal memory to your PC and restore both afterwards
[Xperia Z1 Android Development] ehbm:
ok thanks!
[Xperia Z1 Android Development] New Folder:
I did this, everything was OK! But now i am getting bootloop.

I tried to do Factory reset but still not working. :(

Edit: Flashed Stock tft and now wondering how can i verify that it indeed unlocked BL ?

Figured it out and if anyone is wondering: *#*#7378423#*#*

Service Info > Configuration

If its Bootloader unlock allowed:Yes/No, then its not unlocked.

And if its Bootloader unlocked:Yes, then its unlocked.
[Xperia Z1 Android Development] noobz1:
I lost my TA backup :(

If i relock my bootloader in this way, is it the case that i still lost my warranty?
[Xperia Z1 Android Development] mirhl:
You don't loose your warranty by unlocking your bootloader. Take this into account.

Developer.sonymobile website itself use a modal verb before the word "void".

And that's may.

Now, I'm not a lawyer, anyway I would find fair to suppose that you void your warranty if with unlocked bootloader you manage to brick your phone. But I don't think that if the speakers stop working they could legally charge you to repair the phone.

Said this, if you want to be 100% sure, just relock. It's not important how
[Xperia Z1 Android Development] YaqubYahya:
Hey guys I've requested an email from sony to unlock my bootloader, after half an hour I had no email, I tried another email and its been an hour and still no email from sony to unlock my bootloader, what am I supposed to do now? If I cant unlock bootloader I cant install recovery or install a Custom ROM. Is there another way of unlocking the bootloader or installing a custom ROM?
[Xperia Z1 Android Development] mirhl:
I hope you bl is unlockable at least

Anyway.. In this case the tips are the usual: check the spam folder, trash.. Check for filters.. Nothing else

You need that email for the code
[Xperia Z1 Android Development] YaqubYahya:
Yeah it is unlockable, woke up this morning and still no email from sony to any of the 4 emails I've tried :/ checked spam, junk everything. Would someone be able to try get an email from sony and send me the code? I'd highly appreciate it!
[Xperia Z1 Android Development] dedei:
This sound crazy but I made a nandroid backup and re-unlocked my bootloader using flashtool.

I proceed to restore my nandroid and checked all the boxes (TA included) and somehow it restored everything INCLUDING my TA partition, locking the bootloader and restoring x-reality. I unlocked again, and this tme I didn't check TA on my restore, and it kept my bootloader unlocked. So if you ever made a TA backup on TWRP, there's still hope!
[Xperia Z1 Android Development] Afterlife737:
I need to get my Xperia Z1 back to stock factory settings. I'm rooted, have an unlocked bootloader and a custom recovery. I backed up my TA when I rooted...... In which order do I proceed and where can I find a guide ??

thnx!
[Xperia Z1 Android Development] mirhl:
Restore TA and flash stock FTF

Remember after TA restore phone won't be able to boot with custom kernels
[Xperia Z1 Android Development] Afterlife737:
But that won't relock my bootloader and unroot me will it? :eek:
[Xperia Z1 Android Development] mirhl:
I though when you meant "stock factory" you didn't want it.

Anyway you can at anytime root while still having unlocked bl (but after you flashed stock ftf), or lock it nevertheless and using common root tools (assuming the build you flash is still hackable)
[Xperia Z1 Android Development] [Fenix]:
Hello guys...Long ago I unlocked the bootloader having installed JB ftf and now I have the impression that x-reality doesn't work, tried also with several mod for UB... now I want to re-lock the bootloader and then unlock it again with a KK ftf to test x-reality...if I follow the procedure on OP would this process go well?

Thanks

[Xperia Z1 Android Development] dedei:
I can confirm that it doesn't work on 4.4.4 for unlocked bootloaders. Tried several mods and nothing changed!
[Xperia Z1 Android Development] [Fenix]:
Thanks for reply buddy...so it's not true that x-reality works on UB on KK

Inviato dal mio C6903 con Tapatalk
[Xperia Z1 Android Development] dedei:
Well, it used to work in 4.4.2, but I guess they ~fixed~ it on 4.4.4.
[Xperia Z1 Android Development] deboopi2:
I have a Z1 Compact running kitkat 4.4.4 and the xperia is rooted.

I rooted the phone when running 4.4.2.

When I go to the service menu it says the phone's bootlooder unlockable is YES

I'm running androxyde and trying to unlock the bootloader .

But putting the phon en flashmode with the volume up button pressed when connecting to the pc I get a dialog with the imei number and a question for an unlock code, but I still need to get this unlock code from Sony.

I thought the flashtool from androxyde allowed to unlock the the bootloader without Sony knowing you're doing this.

How does it work ?
[Xperia Z1 Android Development] mirhl:
Sony is not NSA.. they are not spying on you. And no, warranty will still be valid if you don't mess up things

Anyway, there's no unofficial methods to unlock BL
[Xperia Z1 Android Development] -Happy Feet-:
I have an rooted Android 4.4.4 (133) Xperia z1 is it possible to unlock the bootloader with this ROM?

Gesendet von meinem C6903 mit Tapatalk
[Xperia Z1 Android Development] mirhl:
This is not a rom..

It's just a guide to use the official (and the only working) unlock bootloader method
[Xperia Z1 Android Development] mirhl:
-plz delete-
[Xperia Z1 Android Development] kunaal2580:
delete post.. problem solved
[Xperia Z1 Android Development] dedei:
I can also confirm that if you re-unlock your bootloader using flashtool, it won't wipe anything. And you can make a twrp backup of your stock kernel and TA partition, so you can relock it on the go ;)
[Xperia Z1 Android Development] Thug-Mentality:
Hi I tried to unlock my phone and I had the Sony code and every thing is done using flashtool .

My problem some ROMs don't work the only ROM worked for me is the evo9 ....

In the dailer I entered the code to see if I'm locked and it fails to open configuration nothing shows ??? Is something wrong???
[Xperia Z1 Android Development] xerwudjohn:
is this method can also restore you DRM keys?
[Xperia Z1 Android Development] mirhl:
nope, you had to backup them the first time.

Now you can just relock
[Xperia Z1 Android Development] firdyRAY:
Just a quick question.

What are the risk of unlocking the bootloader from flashtool? What is the success rate?
[Xperia Z1 Android Development] mirhl:
No risk. It still based on the official unlock method
[Xperia Z1 Android Development] ExterminalPT:
Anyone know how to keep bion-z working after unlocking bootloader?
[Xperia Z1 Android Development] mirhl:
You can't.

Though, you can backup TA (before first unlock)

This way you'll be able to roll back at anytime
[Xperia Z1 Android Development] ExterminalPT:
Yes, i unlock my bootloader but i relock again with my TA Partition backup :P pictures in low light conditions are very bad with Unlocked BL :(
[Xperia Z1 Android Development] ExterminalPT:
I unlock my bootloader, but with the TA Partition backup i relock again. Now can i unlock bootloader again ?
[Xperia Z1 Android Development] mirhl:
Sure
[Xperia Z1 Android Development] ExterminalPT:
In the first time I use original Sony method, now I need to use flash tools to unlock right ?
[Xperia Z1 Android Development] mirhl:
Flashtool unlock and sony official unlock are the same thing
[Xperia Z1 Android Development] ExterminalPT:
So, if i want to unlock again and use sony original method it will work right? :)
[Xperia Z1 Android Development] mirhl:
Yes.

The unlock code is still the same of the first time.

Besides, if you are switching so often between locked and unlocked status, I would suggest to backup even unlocked TA, so that you'll just need to flash it to unlock without /data wipe
[Xperia Z1 Android Development] bsmstar:
Guys, after unlocking BL I'm unable to do screen mirroring, is that related or not? Thx

Locked bootloader

Hello I got a C6906 and I have the bootloader locked.... and I am on Android 4.4.2...... How can I update to android 4.4.4? :good:
[Xperia Z1 Android Development] Peaceful Droid:
Install PC companion (PCC) or Sony update services (SUS) on your PC and simply update it.

Or find 4.4.4 latest .ftf and flash via flashtool.

Every thing you will find on XDA & Sony support site.
[Xperia Z1 Android Development] mirhl:
SUS has been discontinued afaik
[Xperia Z1 Android Development] Naruyasha:
Hello! I read somewhere that if my phone's manufacture date is 11W29 or PAST 11W29 I should not attempt to unlock the bootloader because the phone will hard brick, is it true? My Xperia Z1 says "13W39" but the bootloader can be unlocked as I have checked multiple times, please help :(
[Xperia Z1 Android Development] mirhl:
I think you are referring to xperia 2011 not unlockable phones and the unofficial unlock method.

You are just fine with Z1 though
[Xperia Z1 Android Development] kidrock23:
To revert back to stock kernel, when I only leave the kernel part in the exclude window of flashtool it shows 3 contents ; Kernel.sin, rpm.sin & loader.sin. How do I select only Kernel.sin as per instructions.

Also after I lock the bootloader, I need to reload TA backup and I can reload the stock FTF from flashtool?, Can I also reload TA backup on unlocked 4.4.2 with V20 doomkernel.

Sorry for the Noob questions but coming from a note this seems more complicated.

Yes you can.
[Xperia Z1 Android Development] Hate Android Lag:
how?
[Xperia Z1 Android Development] blueether:
How did you unlock it? I think the answer to that will give you the answer to how to relock it (or search, it has be posted many times how to relock a bootloader on the xperia Z line of devices).
[Xperia Z1 Android Development] Hate Android Lag:
through the official way. when i recheck that tutorial, it doesnt say anything bout relocking.
[Xperia Z1 Android Development] Xentar712:
I'm stuck in a boot loop after unlocking my bootloader. I think it might have something to do with having dual recovery installed and/or a custom rom installed with a LB beforehand. I get to the sony logo and a bout 3 seconds of graphics before it reboots again. I can get to fastboot mode but not recovery. Any ideas of how I can get out of this? Anyone know if you can flash recovery via fastboot?

Edit: Nm, I figured out a way to flash cwm via fastboot. Now I'm working on a sideload rom installation. Hopefully that does the trick.

Hi there I need a little help with ulocking the bootloader on my xperia z1

Trying to unlock bootloader on my xperia z1 device. followed instructions on how to unlock bootloader from the sony developers website.

got an unlock key but when executing the command to unlock the bootloader I am getting this error

Remote (command did not succeed) and when executing the command again is giving me a message device is already rooted while it isn't. Now i have been looking on the internet for a solution but cannot find one except a lot of people with the same issue.

could you help me out. Oh and I have tried different computers with different os and all giving the same result.

fastboot.exe -i 0x0fce getvar version

version: 0.5 finished. total time: -0.000s

fastboot.exe -i 0x0fce oem unlock 0xmykeyfromsony

FAILED (remote: Command did not succeed) finished. total time: 0.031s

all drivers are installed correctly, tried different computers with different os all giving the same results, when trying flashtool it says unlocked but it isn't

oh and bootloader unlock is allowed.

help would be appreciated a lot.

[Xperia Z1 Android Development] mirhl:
No way
[Xperia Z1 Android Development] NexusGTS:
it doesn't say "relocked " like htc and other devices?
[Xperia Z1 Android Development] mirhl:
If you restore your backup it's really identical

Otherwise if yiu use method 2 (plain relock) technically it could be possible to say you touched it

Though people in repair centers just check whether status is ublocked or not (which is not)
[Xperia Z1 Android Development] NexusGTS:
And one thing , if i unlock it relock it restore the ta partition is there a chance that i will have problems with bravia , camera and other apps?

I tried to unlock the bootloader but getting FAILED (remote: Command did not succeed) Any solution?
[Xperia Z1 Android Development] mirhl:
Couldn't you just read second post?

Is your phone "unlocked allowed: yes"?
[Xperia Z1 Android Development] darsh11192:
Yes... I have checked it twice.. It says bootloader unlock allowed yes
[Xperia Z1 Android Development] mirhl:
So perhaps you mistook "formatting" the unlock code. 0x should proceed it iirc
[Xperia Z1 Android Development] darsh11192:
I have copied the unlock code from the sony site... Where the fastboot code is coming along with key.. I copied and paste that thing... But got that error
[Xperia Z1 Android Development] mirhl:
As i said, that code has to follow 0x. Read the instructions in the first post
[Xperia Z1 Android Development] darsh11192:
Yeah i followed that only... Btw one question... To unlock bootloader is it necessary to be on stock rom and to have a factory reset before starting the procedures?? Because i am on Ihacker rom and did not factory reset before starting procedure
[Xperia Z1 Android Development] mirhl:
You just need to enter fastboot mode. Just that.

Remember that data partition will be wiped

i try to root with Root by binary.

Can anyone help me??
[Xperia Z1 Android Development] LSD DREAMER:
To lock your bootloader just flash your backup of your ta partition in flashtool. Just make sure you are on stock rom and kernel.
[Xperia Z1 Android Development] darsh11192:
will restore ta.img will again make Bravia engine work?? after relocking the bootloader
[Xperia Z1 Android Development] mirhl:
Restoring ta partition will relock your bootloader.

And yes, everything is going to work as a brand new phone (even though there are hacks to use bravia and drm woth UL)
[Xperia Z1 Android Development] darsh11192:
I have never heard about that hack... Can you provide me link??? But i feel like on ul bootloader their advance stock kernel consumes more battery than locked stock kernel... So i would like to stay on locked more atleast till we get lollipop which is most probably coming next week...
[Xperia Z1 Android Development] mirhl:
http://www.xda-developers.com/restore-lost-functionality-unlocked-xperia/

And who's their? Sony? Custom kernels are not theirs. Anyway, you can still use stock kernel with ub.

Or you can install a custom rom

Unable to unlock bootloader on xperia z2 6503

I am unable to unlock the bootloader on my xperia z2 6503. I have the adb installed, I am using the flashtool method to unlock and not going to sony website. My phone has bootloader unlock allowed as "Yes" in the service menu. But when I try to unlock using flashtool, it asks me to connect the phone in flashmode and I connected the phone in flashmode and then after running a few things, it asks me to connect the phone in fastboot mode and I connected it in fastboot mode. But after this it asks me for an unlock code and doesn't proceed further without it. If I repeat the process, the same thing happens again.

My understanding was that if I use flashtool to unlock the bootloader, I don't have to get an unlock key from Sony.

Can anyone tell me what I could do, is there no way to unlock the bootloader without contacting with Sony?

Thank you.

You need unlock code from Sony even with Flashtool.
