Can't update to version 9.1.A.O.489

[wdejong7]

Good Afternoon,

I have requested this unlock boot loader key. But i can't longer official updates for my sony xperia T.

I haven't use this unlock code or use an other rom. Could you make a reset in your systems? So i can update my sony xperia T to the newest update.

Sorry for my bad english.

Thanks in advance.

Greetings,

Hello

What problems are you facing while updating your phone ?

[wdejong7]

When i try to update via sony companion. The system wil give code 2300 (not possible to update in connection with your ammended rom)

I haven't use this unlock code or use an other rom. Could you make a reset in your systems? So i can update my sony xperia T to the newest update.

I hope you can help me.

Thanks.

wdejong7 Try using SUS to update your phone

SUS ( Sony Update Service)  ... download and install it on pc and follow the on-screen instructions

I'm back with some valuable info

SUS and PCC doesn't makes any check on any system of requested keys.

it just runs a check on the phone. So it seems your bootloader is unlocked.

I think you unlocked it by mistake,

But i've got 2 ways for you to update to Jelly bean 9.1.A.0.489

First is to use Flashtool by Sony

1) Download this package -   http://dl-developer.sonymobile.com/tools/Flash_tool_for_Xperia_2.zip

2) Extract it using winrar or any other software

3) Install Emma on your computer and read the instructions in Pdf

Second way is to flash using this Guide

With this tool it is possible to dowgngrade my phone. But when i will upgrade them to the newest version, the tool say...the service has been deleted or your acces has been resolved. Can you help me about this problem?

I was finished with the second way. Thanks for your help!
