HELP! Softbrick LG L9-P768
Bro, I have problem on my phone, the model is LG L9-P768, I flash thru temporary CWM a custom rom which is only a patch to a custom rom, now it is stucked in LG Boot logo, if I boot to recovery (Power+Vol.Up+Home), it is locked.. It can go to download mode. When I connect it to PC, it was detected and installed some drivers but the OMAP4430 is not installed and every tool I used like KDZ offline cant detect my phone, it only reaches the 3rd stage of the installation and in 15% of it, it failed and ask me to retry, even after many retries, I failed.. how can I fix this? I hope someone can help me in this problem...
