Unroot Samsung Galaxy Pro and Install stock Gingerbread OS

After showing you how to root the Galaxy Pro, now we will be checking on how to revers, meaning that by following this step by step guide you will be able to learn how to unroot your Samsung Galaxy Pro and install the stock Android 2.3.6 Gingerbread firmware into its system. Similar with the root operation, on the present procedure we will be use Odin for flashing the stock Gingerbread OS and for relocking your Galaxy Pro, so you have nothing to worry about, as the update operation is easy to fill and to complete.

Therefore, this guide should be used by those who need to restore the warranty (when gaining root access the warranty gets void) or by those who have installed a custom ROM that isn’t performing well and the flashing the stock firmware is the only way in which the problem can be resolved. Unfortunately, if your Galaxy Pro is currently running on a custom ICS, or Jelly Bean based software, now you will downgrade your device to official / stock Android 2.3.6 Gingerbread system. Anyway, don’t worry as you can then re-root, or re-update your phone to the same ROMs.

By completing this guide, your Galaxy Pro will be relocked, meaning that the root access will be revoked, the bootloader relocked and the factory restrictions re-installed. Actually your Pro will be on its initial, or default state. Now, if you do need to downgrade your Galaxy Pro to stock Gingerbread OS then complete the steps from below which will easily take you through the flashing operation. But before that, make sure that you have prepared your device for the update operation that will follow; just take care of the pre requisites which are being listed below.

  • This is an official operation as the stock firmware will be once more installed on your Galaxy Pro and that’s why the root access will be revoked and the warranty restored.
  • Also, if your phone is installed with a custom recovery image, the same will be replaced with the stock recovery.
  • As mentioned, on the flashing operation Odin will be used, so a Windows running computer, your handset and its USB cable are being required.
  • Then, it is recommended to backup the data that is being stored on the internal storage memory of your phone.
  • Use backup and restore apps for saving the contacts list, call logs, EFS folder, market apps, text messages, and everything else you might need.
  • If possible you can also apply a Nandroid backup for saving the current ROM.
  • After saving your personal info, you need to deactivate the security protection from your computer and Galaxy Pro because these programs are usually interfering with the unroot operation.
  • Also, it is important to charge your device before starting the flashing procedure (especially if you notice that there is less than 50% power left) or else you can brick your phone (if it will get turned off while Odin is running).
  • On your smartphone the USB debugging option must be enabled and the drivers should be installed on the computer (if not download and install Samsung KIES on your PC).

You can proceed to the next and final section of the present step by step guide. But be aware as this tutorial must be applied only for the Samsung Galaxy Pro model number GT-B7510. Using the steps from below for a similar device will probably brick the same, so try not to mess things up; just stick to the steps and everything will be fine.
