help me...lg p920
Please i really need your help. I have a big problem.
What really happened is that i first got my lg p920 rooted with cwm 6.01, then i backed up my current os which was android v2.3. After that, i loaded an os from sdcard named 'p920_PAC_jb-alpha-v18.0.0'. When i rebooted......the screen first show like its spoilt or broken, later the os came up but the os is 'BAD'.In short the os is BAAAD AND NOW my phone doesn't receive network, it hangs, reboots itself, and when i remove battery and insert back, the phone turns on itself.
please i need your help as to how to go back to my original lg p920 v 2.3 rom.
i have tried all ways to do it but not successful and i think the best way i can do now is if you can supply me a link where i can download original v2.3 rom which can be installed from sdcard using cwm.
Thanks in advance bro.
