I installed v30b for test but now i want to go back on cm10. I flashed a stock v20 with cwm with smartflash and i was able to boot in recovery. I tested to load my v20 rom but that alway come back to recovery, impossible to load my v20 rom. So, i tried to install cm10 and all was ok.
I rooted my optimus V with gingerbreak and decided to factory reset it today for some reason. I factory reset ted it then it got stuck on the LG logo. So I took my battery out then in and turned it back on and it was still stuck on that logo. So I took it back out and back in and help volume down+home+power and it showed the LG logo for a split second then the screen goes blank.
First lets understand what a factory reset does. It removes all USER DATA and restores the phone back to factory settings providing that the phone is not rooted. User data is defined as apps, call logs, contacts, and anything else the user has placed in the phones memory. Stuff that is on the SDCARD is not affected by a factory reset.
I don't know what went wrong but when I tried to unlock the screen this morning, the touchscreen didn't respond. I tried to factory reset by boot recovery but I can't select the option "wipe data/factory reset" with power button. I hadn't activated the option 'usb debugging', so I can't use android sdk to factory reset either.
How can i do the factory reset in android using ADB command?
I had used adb reboot recovery command to get reset. But third party applications couldn't be cleared somehow.Is it correct way to achieve using ADB?
Actually, I want to do factory reset android devices through java code.What can be solution here?
