You can mix the CSC file but not the pda & modem, but u need to ensure the rom have same PIT requirement or it wont boot
Remark: Dont mix chinese CSC with europe rom, the customade chinese program from eg JH1 CSC will not execute.
I realised that DXJG4 dont have the XME csc file, so even u flash XWJM5 pda + XWJM3 modem + DXJG4 CSC you wont get maxis setting. So just to share with you all in case u really wan the XME csc you can extract the XME content from \system\csc from a DXJF4 phone using root explorer then inject the XME folder into the phone that u need the XME csc.
Method:
1. U need root explorer installed
2. Get the XME content from DXJF4 phone at \system\csc\XME --> copy the XME folder to the sdcard
3. Transfer the XME folder to the phone u intend to install XME csc to \system\CSC\ --> u should have \system\csc\XME by now
4. Open the dialer then key in *#272*HHMM# --> HHMM is the present time of ur phone in 24hr format
5. The Sales Code Selection menu shall appear & the current code you have is SER --> default fr XWJM5 rom
6. You should only see one option of sale code to change which is XME --> If you copy other CSC folder then u shall have more option to choose eg SIN --> I would advise you to inject the CSC folder that u need coz the rom space is limited, dunno what will happen if u put too many CSC into the rom
7. Press the "Install" button the phone shall reboot, the scripting screen shall appear & display all the activities of the new CSC installation
8. Phone will reboot one more time & you'll get the maxis configuration like the DXJF4
I can confirm it works coz i did it & using it
I had extract & pack the JF4 CSC below:
