samsung s8500 and bada restore

[zkyge]

hello i had bada 2.0 on my samsung s8500 and installed something called LionDroid[kitkat 4.4.4] and yeah the system is honestly complete trash. i cant even runany app from the playstore like facebook messenger and my internet (Wifi) is very slow like 30kb/s. no idea whats going on. also i installed the whole system on a SD card and without the card plugged in the phone wont turn on. what am i supposed to do in this situation? i would like my SD card back and the phone running without it on it default system most likely
