How to get more credits in Asphalt 8 in LG Google Nexus 4 mobile Android Version 4.4.4

[karthik balakumar]

Guys, I tried all the possible scenarios with GameKiller. But still, it is not working. either the Knockouts are not getting loaded with keyed in value or when i key in more values say '9999..' the games abruptly ends with "Asphault 8 is not working. Click OK to close.".....

Can anyone help me out here? Appreiciate it! Thanks!!
