Question..

can it will be fix if i downgrade my FW to build number 4.0.1.A.0.284 again just like i first buy it?.

And,if yes,when i can download FW 4.0.1.A.0.284 for my Xperia Active?

I now use FW 4.0.2.A.0.62 but this problem still exist on my phone.

I'm affraid if i have to change my screen with new screen.Because its take too long long time on my country,maybe about 3,5 month and its also too expensive.

Maybe anyone here just have same problem with Xperia Active can help me how to solve this problem??

Thanks.

Strange, it's supposed to work everywhere in the world.

You're left with no toher option but to try in Argentina,

Do remember to tell the results once you repair it

Still doesn't work, I tried here in argentina with both programs and still get the same error.

Nabeel

franlovera Is your phone modified in any way ?

Did youu ever use flashtool to flash your phone ?

Ever rooted it ?

Installed another Rom ?

franlovera

I used flashtool about 5 months ago to root it, and a few weeks ago, I used it again to flash it again to unroot.

I've always used the default roms, and I can update the phone through the update service in the phone.

Nabeel

That's it

Now you have to flash another stock firmware from here

I tried flashing all those firmwares, but they're the same one I used to flash it originally. I followed all your instructions but I still get the same error.

I installed cerberus (GPS tracking program) in place of system framework; its supposed to provide extra security so a theif cannot delete the program, could this be the problem?

Nabeel

I installed the app and the update procedure is working fine.

Might be that you have different settings in the app, this app could be a cause for the error.

If even flashtool doesn't works then surely this app is the culprit. Because flashtool doesn't check anything in the phone unlike PCC/SUS and it just flashes the firmware
