How to install Drivers?

[babsi]

Got another problem, after installing "Sarmads_mod_of_9.21_by_BLKSnaker" cam-driver in IFS/SETTINGS/CAMERA wiht xs++3.0 following the tutorial my phone dont starts anymore when i press the power-button. whats wrong?

edit: i downloaded XS++_V3.1_Darwin and uploaded the "original w800i 4.5" cam-driver to the phone. but it still doesnt work.
If needed, my phone: k750i@w800-R1BC002, unlocked with .vkp, CID49, DB2010, red

edit2: fixed the problem. with setool2 i wanted to write the script "w800_R1BC002_flashLight_on-off_camera_button_v3.1.vkp", it didnt work (got the "some patch values differ" problem and clicked on NO) but the phone is starting again.

i think its because setool2 does this:

LDR:051207 0928 NPACXC1250165_1_SEMC_COMPACTFLASHLOADER R2B
Flash ID check:200D
Flash props sent ok
 
DETACH CABLE FROM PHONE.
REMOVE BATTERY FROM PHONE, THEN INSERT IT BACK
THEN PRESS "READY"
 
Trying to launch embedded bootloader...
INT LDR:COMPACT_ID_LOADER_CRIPPLED_SETOOL2_R2
Flash ID check:200D
Flash props sent ok
FOUND: R1BC002_CXC1250092_EU_1_CA
Restore from:R1BC002_CXC1250092_EU_1_CA 

so it might be something with the xs++. it seems it doesnt switch back to normal phone loader.
