I have put more than 12 hours of my time, before creating this thread. I have tried things, but still struck, so thought to post it in a new thread. Thanks for all your time.
Currently struck in,
fastboot mode started udc_start()
I tried, fastboot erase recovery -> fastboot flash recovery recovery.img -> fastboot reboot (successfully). But it still struck at same place after reboot.
I tried with different recovery images, but still the same observation. I tried to boot by key combination (volume down+home+power), still same observation.
Earlier, I installed ROM manager through google play and installed CWM recovery, version 5.xxx (which I feel now is a mistake), as I tried to install CM11 from MukilSoni, which needs CWM version 6.xx +. I am able to go into recovery and select CM11 image through CWM and proceed with install steps. But, after initial selection in CWM (like app install, etc) it rebooted and went into fastboot mode.I checked the log, it ended with some return error 7.
Then, I tried to Google and check how to recover from fastboot mode, but all failed. I didnt tried KDZ method, but thought to hear from you guys before making it more messy.
Glad, if I get any help and appreciate it.
Thanks for reading it and your time.
