NOTE 1: IF YOU ARE UNROOTED AND ALREADY UPDATED WITH OTA, YOU CAN STILL USE THE PROCESSES BELOW TO ROOT AND FLASH RECOVERY.
>> Rooting Samsung Fascinate
>> Flashing Clockwork Recovery
NOTE 2: IF YOU ARE ROOTED AND WANT TO KEEP ROOT, DO NOT INSTALL VERIZON OTA UPDATE. WAIT FOR DEVELOPERS TO POST A ROOTED UPDATE.
If something went wrong and you did not have recovery installed, use Odin to restore system to stock >> Odin Restore files to get you to stock
If something went wrong, but you are still able to get into clockwork recovery >> Stock Nandroid Image
NOTE 3: IF YOU ARE ROOTED, HAVE LAGFIX AND APPS REMOVED, DO NOT INSTALL VERIZON OTA UPDATE. YOU WILL RUN INTO ISSUES. YOU NEED TO COMPLETELY GO BACK TO STOCK, THEN UPDATE. YOU WILL LOSE ROOT.
If you want to stop the OTA update notification, use this file which provides simple edits...but be careful as it may make further updates more difficult >> SCH-I500.DI01 Update
OTA Update with Root and Busybox >> DH12 to DI01 update with root and busybox
Please post corrections and I will update the OP...I see too many people messing up their devices. Just want to help.
