Greetings friends, publish weeks ago my problem Zr Xperia C5502 which has no IMEI and Baseband showed it as unknown. I look forward to once again for your help. I did my best to repair, restore to PC Companion, Flashear each Roms by Flashtools (4.2.2-4.3 and 4.4.4), putting on CM 11 CM 12 and AOSP and in no way could solve the problem. I can only use the phone with Indian Stock Rom version 4.1.2 but can not use Wi-Fi or the mobile network, nor does the Bluetooth and NFC. Nor do I served DRM restoring Partition Keys or TA. This has no solution? I hope to receive your support in case anyone happened this situation as me and that they can share with me. Greetings and hope your help!
Try to relock the bootloader..restore DRM.and then unlock the bootloader again.

Friend did not work what you said, there will be another solution? There is an option where I can retrieve the IMEI and baseband ?? When I connect my phone to Seetools me recognizes the IMEI and is the same as in the case of the phone.

Any chance you could make an FTF, im guessing yours is unbranded / SIM free?
I want to remove the o2 branding from mine.. .
Theres a guide on how to create FTF files, but it does mean you will have to restore your phone to stock...no worries if not, im sure a Generic Global FTF will appear shortly.

A quick note on root, it works fine, but, there are some residual issues:

Even if i mount /system as RW... a few seconds later, device reboots...?
I'm on O2 UK Branded firmware.
[Bin4ry]
Yes thats what it does. It has nothing to do with a faulty root, it is just a security option on the Xperia T which should prevent modifications to the System partition. When i have time i will take a look and tell which daemon on device it is so we can kill the daemon and modificate the system partition.
Regards
Ok, i rooted my Xperia T with the above method but when i change something in the System folder the phone Reboots and puts it back to how it was
any ideas??
Build 7.0.A.1.303
----EDIT----
Working perfectly now. I just installed V13.
Use V13, i restored my phone completely using PC companion, then re-rooted, i can mount /system as RW, replace files etc..all ok.
Worked for me.
I just bought an xperia T and it was sold to me as an unlocked phone. But, it has a locked bootloader( from vodafone uk). I am wondering if its possible to get it unlocked(paid or free) or atleast put a stock sony firmware even if it has locked bootloader? I am new to xperia and I dont know much about flashing..
Thanks.

Read the all in one thread in the Q&A section. All your answers are there.
Briefly.
You can easily get a free unlock and easily root if you dont want to unlock.
You can easily flash stock sony firmware without unlocking or rooting.
Basically read the all in one thread and ask any questions there

Xperia TL locked bootloader
Hi,
I rooted my Xperia TL with a locked bootloader, and I read somewhere that I can only install custom roms which are based on the stock rom. Is there anyway around this?
No
Sent from my star trek communicator
Sony Flagship device circa 2145
Didn't work on my T with .195, in either normal mode, or 'new' mode.
Also tried to downgrade to 303 but that didn't work either, Flashtool gives an error.
Anyone know if you can use the OTA upgrade to root, and then downgrade back to 195?
You are using the wrong version.
Upgrade to JB then use the latest version

I've recently flashed this http://forum.xda-developers.com/showthread.php?t=2448613 and was just wondering can I still update via Pc companion/SEUS to new firmwares/updates without losing the kernel, root etc...like will it replace the kernel with a stock one?
I'm a noob at Flashing and search didn't really answer my question.
If you have unlocked your bootloader by the official method at unlockbootloader.sonymobile.com, then you can not use PC Companion or SEUS to update firmware.

From what you said, I understand that there is an unofficial way to unlock the bootloader and still be able to use PC Companion and SEUS to update firmware?

If your bootloader is unlocked, there is no way to use pc companion or seus to update firmware unless you relock it
Thankyou for the replies, I might try to relock my bootloader. I unlocked it through the official Sony method.

Not as far as I know. Older Xperia models had test point method, but Z1 does not have this option.

Has someone actually ruled this out? I mostly hear that people with LB go swap their phones or just make sure they're getting a UB phone in the first place. The main complication I see is compromising the waterproof gasket...

Unlocking bootloader doesn't have anything to do with waterproofness, it's something done using a computer.

Obviously. In order to access test points, the back cover will have to be removed. The back cover uses tape/gasketing to enforce waterproofing. My question was about whether someone has actually looked into a testpoint unlock yet for the XZ1.

hi mate. we are on the same issues here. my rooting status is unknown too. some of the devs of xda tried to helped me and we cant fix it. He told me that maybe we are facing this issues is because our bootloader is damaged. and the only solution is go to the sony center and replace your phone to a new one.

After relock bootloader, you can use Xperia™ Companion to repair your phone.
But! You lost your X-reality forever....
So, you better use Xperia™ Companion repair your phone and unlock again.
And then flash kernel to fix X-reality function(DRM key).

Upgrade to last Nougat firmware using flashtool, then you flash androplus kernel and you got root and DRM patch to have noise reduction and X reality working again .
