As time goes by, many are choosing to install Team Win’s TWRP custom recovery over it’s main rival in ClockworkMod recovery. If you are one of those people and wish to do the same for your Samsung Galaxy Express, we’ll show you how it’s done after the drop. Remember, without installing a custom recovery, you cannot upload and install zip files which means you won’t have any custom ROMs. The custom recovery has several other advantages over the stock version, so let’s check out how it’s done:
- You can only use this guide on the SGH-I437 or else you risk bricking the handset. Model numbers are easy enough to find: head to the About Device menu from the Android OS and take a look.
