I have a Grand 2, which I rooted with the kingoroot app. Due to some disadvantages I encountered, I decided to uninstall the root directly from the SuperSU app. Then I proceeded to update my firmware using Kies 3, but it is constantly stuck at 3 %. I have tried and retried this again lots of times, even flashing a stock ROM using Odin, but with no such luck. To make things worse, recovery mode doesn't work, and the I can only enter download mode or, when I attempt to go to recovery mode, it says firmware error and that I should use Kies's emergency firmware update. Can anybody help? Thank You in advance.
