[Optimus One, P500, V General] chiragmodi:
I was running the phone smoothly till yesterday night and then just thought of installing the lastest version of the CM9.0 (hephappy) I was running on bluepill. I then thought I had to update to TINYSTREAM for better performance. I went through a few forums and found out that it could be done without erasing the data or factory resetting. So i was just going through CWM 5.0.2.7 and by mistake i had pressed fix permission... And it started doing so. It took about ten min. ( I did not stop it as I had the fear of losing my phone). I then thought now I'm ready to Update my phone. I then downloaded all the required things(actually only the ROM). And then transferred it in to the memory card. I also had problems with recovery before. I could never directly boot into the recovery just by pressing the Vol Up + Power + Home, as mentioned in other threads. Thereby, I went in CWM and then rebooted through the option given there. And

TADAAAAAA

... Phone got stuck in the LG logo.... This had already happened to me before so I did not panic cause i knew that i could recover my phone( I have gone through it once so had experience) I used the KDZ updater and the went to the emergency mode( That to my surprise worked) and started flashing the V20

And i got an error - The log read as:
