Couldn't find Stock ROM/Firmware

[umiteks]

Dear friends,

I am looking for one day but no result.

I have wiped all my system after root, as a custom from my old CM ROM days, accidentaly.

Now I need to find any;

Stock ROM (firmware) of: Xperia Arc S LT18i - SI 1254-9037 (SA)

but, I couldn't. There are some  other distributions but not for SI 1254-9037.

Isn't there an link of official source from Sony?

Could you advise me please?

Thank you in advance,

[Uliwooly]

the best thing to do is to search the XDA Forum

or use a global generic firmware

Thank you Sir

I just couldn't be sure if any mallfunction may ocur when I flash a generic one.

1254-9037 is what write on the back of phone.

But as I understand, it won't create any problem, right?

Thank you...

Another reason

When I use Sony Update Service, it warns:

"Because your phone has a changed software, software couldn't be changed"

Same also, when I try Phone repair on PC Companion: error 2003

you need to relock your bootloader and flash Sony's firmware so you can use SUS or PCC

Oh

I got it now! Sorry

I Found an explanation:

What the different of this one...

(1254-2716). Generic Global or Specific region I don't know.

As a System no differences ,but as for ME & North Africa there's some Add-Ons

Like Arabic R/W ,SlideME market (google play doesn't work in every country ,e.g :my country) ,and other Things

SI numbers are different from region to other I guess the FW you pointed to is US region

any way I just wanted to share it ,I don't own the device ,mine is SK17i

May be useful for searching same topic...

Thank you again

[Uliwooly]

the SI numbers are different in regions and even in the same country

you can flash the SK17i or SK17a to your phone, it won't affect it
