I unlocked my bootloader using the sony unlocking process. As it was saying my phone couldn't be updated due to modified software, I flashed a stock uk unbranded rom on to it (mine phone is a 6602 bought in Qatar, but the firmware says it's for a 6603).
I then used the flashtool to lock my bootloader. When I check the service settings it now says that unlocking the bootloader is now showing as no. Reading another thread that said by using the SEUS to repair your phone it's possible to change it back to yes, I tried it, but SEUS says that it there is no software available for my phone. Sony Update Engine doesn't have software available for my phone'
Anyone able to get my bootloader unlocked again?

Howsit Guys
Need a lil help here. Im currently on firmware- 10.4.1.B.0.101 with [Root & XZDR] http://forum.xda-developers.com/showthread.php?t=2643898 <-- via this method.. all Works sweetly.. Problem is that i want to unlock my bootloader. Ive checked in the service menu, unlocked bootloader is allowed.
I am currently trying to unlock bootloader with latest version of Flashtools(unofficial way).whilst phone is on, i connect cable, startup flashtools, it detects device. Then i click on lightningbolt icon, to unlock bootloader. menu comes up asking to remove cable, power off phone n goto flashmode.
When i get to the part where it asks to select my device, i click on xperia z. And i get a FAIL message saying i cannot officially unlock bootloader?? Do i need to be on stock .244 firmware or stock kernal to unlock ? Or am i going through it the wrong way. main reason i want unlock bootloader to install cyanagen mod11 nightly.
Thnx
Done
Sorry for the silly post.. managed to unlock my bootloader..
I've recently bought a used xperia z but I'm not sure if the bootloader is locked or unlocked.
So my questions are:
1)How do I check this?
2)If the bootloader is locked does this guarantee me that the (stock) rom has not been "modified" previously?
My concerns at security related.

type *#*#7378423#*#* in the phone dialer
then service info>configuration>rooting status
we will have locked bootloader when we bought it
and no bootloader can be unlocked & relocked so don't know,or you can check if the BRAVIA Engine works on Sony Album app or not

According to this link you can but not entirely sure since I've never done it before..
If this if not the case, could you explain to me a little bit more?
It's possible to unlock and relock the bootloader without leaving any trace that it was done. You can check if it's currently unlocked by looking in the service menu. Enter *#*#7378423#*#* in the dialler, then look in Service info - Configuration.
If you're worried just repair the phone with SUS or the PC Companion. This will completely wipe the phone and reinstall the software from scratch, therefore ensuring that nothing is tampered with.

Hi guys
Just a little bit of a background, my old contract has finished and I wanted to give my phone to my mum in Australia so I flashed their Firmware, here is what I did:
The phone was locked to my network provider and according to a Sony Forum they said that you flash the simlock.ta for phones that are locked to a network.
1. Installed Kingroot and rooted phone.
2. Downloaded the Sony Experia Z1 (C6903) firmware for Australia with XperiFirm_4.8.1
3. Converted the Firmware with Sony Mobile Flasher (FlashTool) to FTF
4. Flashed firmware with unticking the simlock option
5. It asked for using a F?? cript which i said NO to
6. When writing simlock it wanted confirmation to do so, I said yes.
7. Phone restarted and then after setup completed it asked for pin code, immediately after that it asked for puk code, after that it displayed a message saying Sim Unlock Failed
8 . The phone now diplays Invalid card - No Service
9. Followed above with the UK firmware to see if it would fix the problem but still no luck.
10. Downgraded to an old G version of firmware but that got stuck in a boot loop.
10. Ran Sony PC Companion software to repair the phone, which it did, now on the latest firmware again but still No Service.
Please help...

If it doesnt work with the provider it was locked on then it is a hardware defect. I had the same exact problem and I tried every sim card of all major providers here in my country and still it gave me the same message: invalid sim, not service. I contacted Sony support and they had my mainboard replaced within two weeks. That assured me that it is a hardware related problem
good afternoon, I have a problem with my xperia z1 c6903 when unlocking the bootloader I get a message that says your phone can not be officially unlocked that I should thank.
Apparently Sony has blocked the ability to unlock the bootloader on certain devices.
This is most likely the case if you got your phone from your carrier. Do you have a branded Z1?
You can also look up if this is the case by doing the following:
1. Open dialler and enter *#*#7378423#*#*
2. Go to Service info > Configuration > Rooting Status.
3. "Bootloader unlock allowed" should say Yes
If it doesn't, then at least the official way of unlocking your device won't work.
Any "not official" way to unlock the bootloader? Mine is locked too and i want to install something new in that old one. Thanks in advance.
Mine says not posible but i read somewere that can be done
That's the thing, is an old smartphone today, i don't understand why only certains models can be unlocked. Now im on last oficial os (5.1.1). I get it root but i cant unlock the bootloader in any way.
