[Q] How to update rooted SK17i to stock 2.3.4 with unlocked bootloader?

Hi everyone. I've got this problem which i can't solve (nor find the solution on the net).
I have a rooted mini pro with stock 2.3.3. I've unlocked bootloader through sony ericsson website and verificated my IMEI number there. Then i've rooted my mini pro - and kept stock 2.3.3.
The 2.3.4 update is out now (PC Companion says that too), but windows keeps failing to install the MTP USB drivers when i try to connect in this mode according to guide in PC Companion. I gave up trying to update firmware this way after lots of attempts.
So i decided to try update by SEUS. When i connected in recovery mode, SEUS said that software in my device was changed and thus cannot be updated. I really don't know what to do now. I'm afraid that SE blocked updates to my IMEI number as i unlocked the bootloader, but i'm just guessing.
The question is:
Does someone know how to update my mini pro to stock 2.3.4? Is there any way to lock bootloader back as it was and get SE to know that i'm a nice guy again?
Thank you very very much for any help! I'm starting to be desperate about this.

Error after flashing/update software

Hi!
After flashing my M4 Aqua i got error when i turned on my mobile:
"Got Failed TA value at startup! 0x55"
and 2 keys: POWER OFF and Use Phone
After i reflash on Flashtool or use PC Companion to repair error didnt dissapear. Every time i turn on mobile after flashing or after data factory reset i got this error :/ I have locked bootloader and got no root. How to repair it?
Help someone pls...
I'have same issue with xperia M4 aqua Dual, E2333
Error after reset setting " got failed TA value at startup -0x56"
Device work but have not network
Solution please!
Hi. Try flash 26.1.A.2.99 with Flashtool and if succeed, update to the newest available firmware with PC Companion :fingers-crossed:
Remember to keep away 'simlock.ta' file from your device, it may brick your phone/make sim not detecting (always exclude like default selected in flashtool)
If you can't flash 26.1.A.2.99 you can try to wipe your device (factory reset or select USERDATA and apps_log in flashtool), exclude/include both 'cust-reset.ta' and 'fota-reset.ta' files in Flashtool.
Hi! Thanks for answer but is not working for me
I tried this metod and its work only until you factory reset at phone
I mean after flashing .99 error still shows up but after update software at PC Companion to newest error disappears for some time(until factory reset).
So after all error doesn't disappears for ever
The only way is again downgrade to 26.1.A.2.99, update with PC Companion and no more factory reset for now, may coming Marshmallow update can fix this problem or go to nearly Sony Centre or place where you bought your phone, they should know how to fix this
Ehh Yeah I hope 6.0 update will fix it...
I think that custom rom can fix it
Someone has a link for cyanogen or other one?

Installing The Most Recent (Updated) Sony Xperia C4 E5333 Firmware

~ "At your own risk:
Tutorial Flashing Update Sony Xperia C4 E5333 for download errors, application errors, the touchscreen is not sensitive, exposed to the virus internal memory, loading a boot loop, until the hardbrick could be detected in a firmware update for the computer drivers. Below you can find the latest firmware for phones:
How to Flash the latest firmware to Sony Xperia C4 E5333
1.First of all, check your firmware version (if you already have the latest, you do not need this tutorial).
2.Download and install the latest Flashtool from this following link:
http://developer.sonymobile.com/services/flash-tool/how-to-download-and-install-the-flash-tool/
3. How To Use Sony Flashtool Tutorial can be found at this following link:

4.Download the latest Firmware Xperia C4 E5333 from all Sony firmware available in this following link:
http://zonexservice.blogspot.com/2015/06/all-stock-rom-sony-xperia-firmware.html?m=
5.Paste FTF file downloaded in step 4 to the folder "Firmware" in the folder Flashtool.
6.Open Flashtool, click on the flash and select the firmware which was downloaded, click ok. Important - if you do not want to delete the data from your phone, simply uncheck userdata.sin. All data will remain in your phone, but sometimes it can cause additional problems. So it is better and i do recommend too, to perform a backup of your personal data, then continue with the installation raw and then restore your personal data.
7. Turn off your phone and when Flashtool shows a pop-up window, connect the phone to the PC by clicking the volume down key until the green led color appears.
8. After a few minutes all done and you'll get a new updated firmware phone."
Hello, this is my first time here - I'm from brazil, so, first, please excuse me for the bad english.
I have a C4 Dual , model E5343 (Brazil retail), and months ago I've flashed the MEA version, model E5333 - 5.1
Now, the official 6.0 update of the E5343 is available for download with Xperia Companion. I've tried to download this version and flash it with the flash tools. All drivers and services are installed and activated (in 2 PCs), and I've downloaded 2 versions of the flash tools - both of them didn't worked. So, when I was about to flash, after selecting the model C4 (E5xxx), I've always got this message - Process finished with error - loader.sin.
Later I've tried to do the recovery with Xperia Companion, and it gives me this error message: UEGetPhoneInfoMissingInfo
E5343 3521 1295-0292 R3A 27.2.B.0.169.
What should I do? Wait for the OTA update? Or can I do anything to fix this errors so I could flash it correctly?
PS - Using fastboot or unlocking the bootloader would help somehow?
Thanks!
would you need to unlock bootloader first before you can flash?

Bricked Sony Xperia XA1 ultra dual sim g3226

Hello Everyone
I need to ask you all for help.
Namely, I have Xperia xa1 dual sim g3226 ultra with an open bootloader.
Two days ago I tried to upgrade and get into trouble. I found firmware and flash it by Sony flash tool, but everything ended incredibly fast (about 15 sec) and now I have bricked devices.
The real reason is not clear to me, but now I can not get in fastboot or download mode, just got a red light when phone is connect to pc and "unknown devices" in the device manager.
Does anyone know if there is any solution for me or the Xperia must go in the Sony service.
Thank you

Sony Xperia M4 Aqua E2353 CDA 1293-8060 2
Hi,
Can someone help find the proper ROM file for this specific device?
Sony Xperia M4 Aqua E2353 CDA 1293-8060 2
I have tried all the updated ROMs of E2353 Single Sim from Flashtool and Xperifirm. Still getting boot loop.
And as per Sony's EMMA report, phone is currently locked. I cannot unlock since computer doesn't recognize the phone especially when trying to udpate and repair it using Xperia Companion. Only Flashmode works when connected to computer.
Really need help.
-Julius
