Unable To Flash V802se

I have one V802SE and DSS-25

When I run SE Update Service, V802SE or Z800i are not shown in the supported mobile phone list. I suppose it is too old to be updated via SEUS

I have tried updating via XS++ 3.1, but failed.

I first remove the SIM card and Memory stick from the phone, insert a fully-charged battery and connect the phone to DSS-25 WITHOUT plugging the USB cable into the computer.

Then I run XS++, click connect, then plug the USB cable from DSS-25 to Computer USB port and hold the following keys.
1) holding the "c" button -> nothing happen in XS++, phone doesn't start
2) holding the "c" button and power button -> nothing happen in XS++,phone starts normally
3) holding the "<" button -> nothing happen in XS++,phone doesn't start
4) holding the "<" button and power button -> nothing happen in XS++,phone starts normally
5) holding the "2" button -> nothing happen in XS++,phone doesn't start
6) holding the "2" button and power button -> nothing happen in XS++,phone starts normally
7) holding the "2" and "5" button -> nothing happen in XS++,phone doesn't start
8) holding the "2" and "5" button and power button -> nothing happen in XS++,phone starts normally

I have checked the device list in device manager. I can find the "SEMC DSS-20 SyncStation" Driver installed at COM2 (Version 1.0.2115.0 2002-12-17)
I have also tried selecting "USB" port or "COM2" in XS++, but both doesn't work


Then I tried SEMCTool and test with the "Read all code" function. (I just connect the phone with DSS and plug into my computer). I think it is not in flash mode, but here is the result
SEMCTool 8.7 - Partially CrAcked, don't work with DSS-25, I hate ExeCryptor
SEMCTool 8.4 - Give errors :(
SEMCTool 5 - Give errors :(
SEMCTool 3.3 - "Read all code" function work, but the Flash ARM function has been disabled by cracker. :(
SEMCTool 2.2 - Give errors, the phone simply power on as normal :(


Can anyone give me some hints? Did I do anything wrong? Any other software I should try? :confused::confused:
