About Itel 1406
If your Itel 1406 has been giving you trouble, reinstalling the stock firmware is often the cleanest fix. Here you'll find the full Itel flash package along with the details to check before you begin. Flashing the stock ROM can clear boot loops, failed updates, a frozen logo screen, or sluggish performance, replacing the system software with a known good copy. File Name: Itel_1406_S102_20151008_SPD.ZIP File Size: 471 MB Before flashing, back up your data (the process wipes the device), charge above 50 percent, and install the correct USB drivers on your computer. After flashing, allow a few minutes for the first boot. From there the Itel 1406 should run like a brand new unit.
