How to Downgrade Firmware on Galaxy S Advance GT-I9070 [Jelly Bean to Gingerbread]

151

Do you grow excited when you hear about an upcoming firmware update for your Android phone? Yes, everybody is filled with joy at the very thought of enjoying the latest version of a mobile OS that often features various improvements and enhancements. But how do you feel when a firmware upgrade does not come up to your expectations and, in place of enriching your mobile experience, makes your phone slower, laggy, stripped of an essential feature that matters to you?

It really feels bad to be forced to remain with the lower version of a firmware when the greater is already existing. The Android 4.1.2 Jelly Bean firmware update for most Samsung Galaxy device users have proved to be nightmarish. I say this from personal experience and on the basis of  the great surge of traffic coming to our blog to this downgrading tutorial.

I have never seen such desperate willingness to downgrade firmware among the users of Android devices from other manufactures than Samsung. It’s true that Samsung has been more sincere than any other OEM in respect of launching new devices and rolling out firmware updates and we appreciate that. But does this sincerity lacks soul?- seems it does.

Just take a short tour of our ROM update section and you’ll realize what I mean to say! And if you are reading this tutorial, I am sure you too are one of those unhappy souls who cannot tolerate the degradation in performance of their Galaxy S Advance GT-I9070 after upgrading to recently released Android 4.1.2 Jelly Bean firmware.

Disclaimer

The tutorial given below has been tested by us on Galaxy S Advance GT-I9070 (8 GB variant) and we successfully downgraded our phone to Gingerbread. Despite this success story, we do not take responsibility for any damage done to your Galaxy S Advance GT-I9070. We have only laid out the procedure but it has to be followed by you. If you make a mistake, your device might turn into a costly paperweight. We warn you not to cross this line unless you are sure what it is all about and make sure all your senses are up and sound as you do the drill.

While downgrading an Android device from Jelly Bean to ICS is rather easier, when it comes to rolling back to Gingerbread from ICS or Jelly Bean, things go a little complicated. A single file installation of a lower version of firmware for your device might prove fatal and endanger your beloved phone.

Getting Ready

  • First of all download the following Gingerbread firmware for Galaxy S Advance GT-I9070. The provided 7zip file contains all required stuff (see below), such as the Odin3 tool and the PIT file.

Make sure you have made all required preparations mentioned above and have the downloaded files on your computer, and then proceed to follow the following steps carefully.

  1. Turn of your Galaxy S Advance, and put it into Download mode. If you do not know how to do it, here is the method: press and hold Volume Down + Home + Power buttons simultaneously for about 3 seconds till you see a warning screen. Then press the Volume Up key and your phone will enter Download mode.
  2. Now open the firmware package you downloaded and launch Odin3 v1.85 as administrator. When it is opened, connect your phone to computer using the USB cable.
  3. Wait till Odin detects your phone and when it does it, the ID:COM port will turn yellow.
  4. Now click on PDA button on the Odin tool, navigate to the firmware folder and select the file with CODE in its name: CODE_GT-I9070_I9070DXLD1_CL1068093_REV00_user_SEC_KEY_LD1_8G.tar.md5
  5. Next, click the CSC button and select: CSC_GT-I9070-MULTI-CSC-OLBLD1_SEC_KEY_8G.tar.md5
  6. Then, click the PIT button and select the .pit file depending on your phone’s memory (8 or 16 GB). Ours is the 8 GB version so we selected: GT-I9070_EUR_XX_8G.pit
  7. Next, make sure that “Re-Partition”, “Auto Reboot” and “F Reset Time” options are checked on Odin.
  8. Now you are just a click away from rolling back to the Gingerbread firmware on your Galaxy S Advance. Just click the Start” button and wait till the installation is completed.Galaxy-S-Advance-Downgrage-GB-Odin-pass
  9. Finally, you will get a PASS!! message with green color indicating that the firmware has been flashed successfully. Your phone will then reboot automatically and it will have the newly installed Gingerbread firmware now.

What If I Get a Bootloop after Downgrade:

Well, we have tested this method and it worked without any mishap or hindrance but it is not necessary that things go nice for everyone. In case you phone does not boot properly even after getting PASS!! message at Odin, follow the following troubleshooter:

  1. Pull out your phone’s battery, wait for a minute and reinsert it back to its place.
  2. Then boot your Galaxy S Advance into recovery mode: press and hold Volume Up + Home + Power keys for about 5 seconds till the Samsung logo with device name blinks for 2 times followed by a black screen with an Android bot and blue menu. This is called stock recovery mode and here you will have to use the Volume keys to scroll and highlight options and the Power key to select them.
  3. Now scroll down to “wipe data/factory reset” option and confirm your selection.
  4. Next scroll to “wipe cache partition” and wipe it too.
  5. Finally select “reboot system now” option.

Your phone should boot now and if it is still stuck at bootloop, try installing the firmware again and more carefully. Remember, if you encounter an error, it’s most probably a mistake made on your part.

Installing Official GB Firmware for Your Country:
