For those of you who might be returning your Epic 4G back to Sprint for warranty (perhaps you broke the screen) or maybe you’ve bricked your phone while trying to load a new ROM (which happened to me couple times), you can easily unroot your Samsung Epic 4G to completely stock state by using Samsung’s own tool for unrooting. This will install Samsung Epic 4G’s stock EB14 Froyo 2.1 ROM.
Once you’ve installed this ROM, you can easily upgrade to the latest, stock ROM (EC05 as of today) by going to Settings->About Phone->Update Android.
Another reason why you might want to unroot your phone is to install an aftermarket ROM like Syndicate. It’s much easier to unroot your phone back to stock then install the Syndicate ROM but I will have a complete HOWTO guide on that soon.
Here’s how to unroot your Samsung Epic 4G:
(You will need Windows for this, if you don’t, I suggest running VMware or borrowing your mom’s/friend’s computer.)
*IMPORTANT: Make sure to make a backup of all your important files/apps and whatnot before unrooting!
1. Download the unrooting file:
2. Install the exe file and you will get SW Upgrade for SPH icon on your desktop.
3. Make sure you have Samsung Epic 4G drivers installed.
4. Run the SW Upgrade for SPH program and follow the directions.
It will ask you “TWICE” to put it in download mode and take the batteries out, you do this by pressing down power button while holding down the Volume Down and Camera button.
The first time, it downloads some kind of special drivers and second time it will download the stock ROM and auto-install it for you.
Once you run this, your Epic 4G phone will be back to EB14 stock ROM. You can upgrade to the latest stock ROM by going to Settings->About Phone->Update Android.
After that, you can re-root it using our latest rooting method, then install Syndicate ROM.
