how to get original si firmware

[#1]

Hello

2 weeks ago, i bought a used/second hand live with walkman (wt19i), on good condition

But i did not checked si number on the device.

The original si on the back of battery: 1253-5745 (dont know what region/country)

When i check using *#*#7378423#*#*, this device loaded with 1254-1950 firmware (indonesian si)

My question is:

Will my walkman be allright with different si firmware?

How to get original si firmware?

I did tried to upgrade/repair from pc companion, and the result was the same 1254-1950 previously loaded.

Please help with this couriousity....

Thank you for your answer.

You have a branded firmware.

I think you will most likely get updates way slower compared to a Generic(Unbranded) Firmware.

I advice you to flash it with another firmware using flashtool.

Try this: WT19i_4.0.2.A.0.58_UK Generic(1254-1868).rar

if you scroll down you will see 2.3.4, and once ICS is released for this phone I'll add 4.0.4

Waw, how to get si code information like that? 😄

I have searched for si code info using google for 2hours, and found nothing usefull,,, T.T

Maybe si code thing is classified to public,,,hahaha

No, my phone wasn't sim locked.

When i bought this phone, it already loaded with .58 version.

Then i upgrade it to .62 using pc companion.

Did pc companion find the right firmware using si code on the back of the battery, or using previously loaded firmware's si code?

Iam afraid that when i already flashed generic firmware (1254-1868 for the example), then pc companion will load back default branded firmware (1254-1950) when i atempt to upgrade/repair.

Thank you for the answer. Thats really helpfull info 😄
