Ah Yes - Completely different PC and OS WIn7 this time....

And by flashing differnt .ptt 7kb file, than your original one, you WILL get DIFFERENT languages in phone, whome is btw. NOT supported for fw upgrade via Kies. (C3520 phone itself)

ikut sruput mas boz
thanks cendolnya

wow tnx for this man .. this can help newbies like me

Today I have one C3520, but can not unlock like this.

No need to make flash before unlock, just:

1. make full reset *2767*3855#
2. Click Read codes
3. Connect cable to phone (C3300K)
4. Connect battery
5. Hold down power button

If you put battery, then cable, and the push power, will not go in TAT mode. :p

yess, thanks z3x that i had tried n succes to unlock c3520

try my trick. just make a emergency call and insert code: *2767*2878#

and without lost data...

Worked great thank you mate.

Thanks mate, this worked for me!

thanks working great for my problem ;)

I also had the problem connecting C3520....

and correct way was is like it writes in first post but

No need to make flash or full reset before unlock

2. Click Read codes
3. Connect cable to phone (C3300K)
4. Connect battery

...so just connect cable, press read codes and as soon as you get message to power on the phone insert battery, do not press power, phone sould power on by itself, and every time enter TAT mode, just tested on 10 pcs!

If it doesn't want to enter TAT mode restart computer and reconnect box!!
