Hi I have a s3 t999l lte. And I wanted to use a custom rom. Well first
I flashed cwm but I forgot to backup files. Then after trying
To flash another rom it says secure auth in red letters on odin.
When trying to install zip from ad card it says no files found and when
I reboot it gets stuck in boot mode. Somebody please help me!!
What steps am I missing and can the t999l be rooted?
