Now after unroot mine, in download mode, I got:
product name: SGH-T889
custom binary download : NO
current binary: Samsung official
System status: official
but 'device status' showed 'modified' that I couldn't clear it (I tried everything I could find here).
Is this ok to be sent back to Samsung for warranty work (unrelated to rooting)?
If not, please help. ( I already tried wipe data from recovery, factory reset from 'settings' menu, clear data for Enterprise SysScope etc...)
Mine is stock 4.1.2 from day 1.
