I already did the same thing like you.
But the problem is, sometimes your search results will come out with many places with same hex number.
Eg,if u search this 4B 2D A0 E3 hex number, you will find at many places like 0004f0h, 000fg0h and so on.
I dont think we need to change all cause the com port and baud only specify at one place.
Am I wrong?

I think you're right. Only at one place only. Change at wrong place might result a harmful result.
I think so.. Not sure

It is better and safer to use IDA Pro for finding the correct Hex code. Be adviced that changing the worng Hex code can do damage to the program.

Just a thought.

No, this is just a guideline(There are too many versions around so one can always try 1st)
So safer to "Save as" a new exe name
Location advised to refer to our seniors here

Bare in mind, that his unpacking and changing the com port and baud rate are for education and testing purposes only. This forum do not welcome for those who are using all the software here for profit / selling purposes.

Just a thought.

0x240h 64 61 74 61 --> 55 50 58 32 --------------------- UPX2
0x3e0h C3 55 01 97 --> 55 50 58 21 --------------------- UPX!
Then save the file as papago.exe.

[color="black"]Unpacked papago.exe using UPX 3.04[/color]

In command prompt: type: upx -d papago.exe?

[color="black"]Unlock,Change COM & BOUD (Using ultra edit)[/color]

Unlock : 0xD014h 00 --> 01
Change COM port : 0x65E28h ---> 01 20 A0 E3 (for COM1) and 02 20 A0 E3 (for COM2)
Change Baud rate : 0x65E44h--> 4B 2D A0 E3 for 4800. The rest see below :

4B 2D A0 E3 --> 4800

4B 2C A0 E3 --> 19200
96 2C A0 E3 --> 38400
E1 2C A0 E3 --> 57600

Baud rate is not that particular. It will still run if it is set to 4800 in a 19200 unit.
