The problem is that you're using files with the extension software. You will find some explanation in this thread.

The files you need must be mbn(for the main) and fbn(for the fs).

I tried again but no luck

And what frimware should i use that could be better than this one because when i turn on my phone it freeze on the wallpaper and it takes about 2 min to continue.

Posted by tranced
Not sure but the files you used it's for CID52 and yours is CID53.

What version of the A2uploader are you using?

Posted by zizolz
I dont know actually .. i found it in google and they've said its the last one but not cid53 compatible and now i found a2uploader cid53 supported .. I'll try it asap and see if it'll work .. but what kind of frimware should i use ?

I have a ˝problem˝ with A2 Uploader.

I'm trying to delete locked files (eg. themes, pictures, sounds) from my phone (C905, CID53) but A2 Uploader won't do it.
I select file which I wanna delete, select SET RW ACCESS and A2 reports me an error, and FS EXPLORER shuts down.

I have newest version of A2 Uploader 22.09. (at least I think it's newest).
I didn't have any problems deleting that files on my old phones, which were, if I remember correctly, also CID53.

How can I solve that?

Posted by devil2887
where can i download the fs and main firmware sir? also the other needed custom..

Posted by ceaser2008
Your main is right. Its generic one, based on your Pm.

If you are from philipines, why dont you try this fs for asiapacific and nz.

http://www.4shared.com/file/R[....]R1FA035_FS_APAC-ANZ_RED52.html


And the custom-pack

http://www.4shared.com/file/l[....]_1201-0102_R11A_GENERIC_A.html

This will have your philipino language as well.

Try this.

Posted by devil2887
where can i get the cda file sir? i need 3 files right?

Posted by ceaser2008
Forget that. You dont need any cda files. You only need main, fs and custom pack. Thats it.

And a2uploader to flash the phone.

Edit. I dont think custom files are called cda files. I think custom files are different and cda files are different.

I have already posted what you require to flash. Now its your turn to do the job.

Posted by devil2887
ow.. thanks sir.. ill try it.. .. the earlier main i've shown u sir is right?

then cust and fs is the one u've given me.. thanks sir

Posted by ceaser2008
Yes your main is right.

Posted by devil2887
sir, it says "can't get ACK"

Posted by devil2887
sir what will i do next? its complete but i dont see any shutdown or what.. stop and quit only..

Posted by ceaser2008
Shutdown button is right below the window where your filesystem was opened for customization. When the process is going on, the shutdown button is not visible. After completion of process, it will be visible.

About that cant ack error, Your phone disconnected in between. May be your fast-port is loose that a little shack of the phone and your cable loose its connection with phone.

is it possible to flash an a2 phone without changing its certificate? what if want to change the camera driver or acoustic? should i change it to brown certificate first?

Posted by mriley

is it possible to flash an a2 phone without changing its certificate?


Yes, you can't change your phones certificate with A2 Uploader, your phone will remain the same certificate when you flash it using this tutorial

what if want to change the camera driver or acoustic? should i change it to brown certificate first?


No need to change certificate, a brown certificate is only needed for advanced modding such as patches and Elf packs.


Posted by zacch00
what if want to change the menu, font? is it possible in red certificate?

Posted by ceaser2008
Like it is said before, you need brown certificate only for patches and elf packs. Rest of the modding can be done in red certificate.

Posted by Pine Sol

Hi there!

I have also this problem that the middle touch screen button (as I termed it) is not working. As I read on forums, I have planned to try reflashing my SE K850. I have the tools needed like A2 uploader, cda generator, my SE unit, USB data cable, Se PC suite and installed usb flash driver in my pc but when I tried using A2 uploader, the pc wont detect my phone. I waited longer for me to see if A2 uploader would take some time in order to detect my phone but hopelessly it's not. Can somebody help me regarding my problem? And my question is that, is it literally the C button that I am going to press? The one which functions as cancel button? please help. Thanks. I need the answers asap

Yes, you've got the right C, keep pressing it

Bought recently four SonyEricsson phones from China, as those models I wanted, just couldn't be found in Sweden.
A C510, a J20i Hazel, a T700 and a W508. All came brand new and working but only with English and several Asian languages.
Wanted to have them with my native language Swedish.

Registered an account with Wotan Server, that for a fee, per phone, flashed them permanently to a Nordic Firmware.
It cost some 2 Dollars for each phone, sadly the Czech company only accept euros.
With exception for the Hazel (which had to be flashed twice coz the first attempt failed). it was quick and easy way to flash the phones via the Internet site Wotan Server.

The Wotan Server demand an account with their site, an Internet connection and programs installed from the site (plus money).

Sadly they don't carry any Firmware for the T630, apparently it's too old. (The T630 is anonther phone in my collection that needs a Vodaphone de-branding)

Anyone interested? Google is your friend.
