So I am still having a problem. Today I received my replacement device from Sprint. Exact same issue.
Originally the ROM was installed on my device, and I was getting some force close errors, so I ran "Wipe Data/Factory Reset" and reinstalled the ROM. It just sits on the Samsung logo for a while and then boots back to CWM.
So here we are again.
I ODIN flashed to Android 2.1, OTA update to 2.2, OneClickRootCWM126.96.36.199-EC05.zip to root, install CWM v. 188.8.131.52, and wipe data, wipe cache, wipe dalvik, and install the ROM and stuck on Samsung logo again. I am going to cry. I need my hotspot back and all my custom stuff.
What on earth am I doing wrong?
