Hi all
A friend of me asked me to unlock his Sony Xperia Z3+
It is the dual sim version, E6553
It had the Xperia lock and a tried different solutions to unlock it, without any success.
I also asked a friend to experiment.
He couldn't unlock it, but when I got back the phone, it had the single sim software, for E6533. Still locked.
Now I unlocked the phone. I made a reset, I can update the firmware, but I cannot flash the E6553 back.
If I try, I get this error:
ERROR - The bundle does not match the connected device
I tried with older flasher, but I get another error:
INFO - Cannot open bundle. Flash operation canceled
I also tried with Emma, but it says Phone is locked. (I already unlocked bootloader)
Phone works correctly with this firmware, but I want to use it with 2 sim cards.
Please advise.
Best regards,
Janos

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?

Hello,
I have unlocked xperia x8 but it won't work with other sim cards. S1 tools shows "2r small as it should show as phone unlocked, but if i try insert new card it cant connect to the network. anyone can help ? :crying: i used msm7227 to unlock and if i try semtools it shows it is allready unlocked, I want apologize if it is already answered but i searched forum and nothing helped.
msm7227? is it the bootloader you've unlocked?
Just because i don't doesn't mean i can't.
Flash stock 2.1 and lock bootloader, everything will be fine.. You have probably used wrong file or you have simlock.
Hello ! Been browsing xda for few years and found a lot of good info here , keep up the nice work. But now i got some issue and i cant find anything to solve it , maybe some of you could help me.
My problem is that i recently bought a Xperia V, was bought i think from JAPAN , on the top writes on it NTT DOCOMO - has a locked SIM card.
What i tried -
-unlocking bootloader with official sony guide , but if i type *#*#service#*#* says to ROOTING STATUS - BOOTLOADER UNLOCK ALLOW - no, anyway to the SIM LOCK - [x] Network - Unlimited , this means i got unlimited tries to the code it locks it ? still didnt found a way to unlock bootloader
-rooted phone, installed custom recovery
But still havent manager to get rid of that simlock , everytime my phone boots up asks a NETWORK SIM UNLOCK PIN.
Status
Model LT25i, Android Ver. 4.3, Build No. 9.2.A.2.5 ( ask for more info if needed )
I can downgrade to any version using flashtools.
Anyone can guide me if is there anything i can do ?

Same problem here..i'm from Philippines and my phone is lock to Smart Communication Network Postpaid. Been looking for solution for this. Hope somebody here in the forum can help us.
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
Z3 compact unlock bootlader sony official method,flsahtool rom flash after "NO SIM C"
Hi everybody
I had a little accident.
I made several mistakes, I know! I read in a similar prblémát, but the solution is not for me!
I have a Sony Z3 compact device! Hungary T-Mobile network loop! I opened the bootlader the official sony method! It was a success. I wanted to try a different system to the phone, but firmware number is the same, I would have pre-Root rom!
I have not prepared a recovery of the original firmware !!!!!
Since then, no phone sim card enter the message.
I downloaded the firmware factory, but all of them wrote it. T-Mobile firmware costumizated I tried, but it did not help. I tried flashing simlock.ta file, the process is successful, but "no sim" continues! Simlock.ta firmvare part of Hungary costumized that you downloaded the firmware inventory flashtool! Simlock not be opened, but to join the network! t-mobile sim card I use, just open bootloader and root around!
I attach a few photos.
Thank you in advance for your help!

If you look through the Q&A thread there are several people with the same problem as you.
Sony are unique in creating an encrypted partition with unique identifier keys on. I think it catches lots of people out who come from the likes of Samsung & HTC where you can go from new to custom rom in a couple of minutes.
There should be more warnings on Flashtool that what you do can be irreparable.
