    New How to Downgrade Galaxy Ace to Froyo 2.2.1 and then update it to GB 2.3.4 using Kies

    Samsung Galaxy Ace specially for Asian countries or others where update to Gingerbread 2.3.4 firmware through Kies were unavailable and users updated their firmware to S5830XXKPH
    Good news Update to Gingerbread 2.3.4 S5830DDKQ5 through Kies for Asian countries is finally released. This might even work with other countries where update to Gingerbread 2.3.4 through Kies was awaited
    The ROM works fine i have tested it myself..

    Here's the systematic guide for downgrading from Gingerbread 2.3.4/2.3.3 back to stock Froyo 2.2.1

    I request you to Read carefully the whole instruction before proceeding, for safety and avoid bricking the phone.

    But don't be afraid this is surely safe....

    To begin with the process, you may first:
    - back up all of your important data, contacts, messages, applications installed or stored on the phone.
    the SD memory card files will not be harmed.
    - use a PC that runs on windows XP or later OS. Close any programs such anti-virus etc.
    - remove the SD card and SIM card to avoid issues.
    - make sure that the phones battery is fully charge or at least around 40-50%.

    Prepare the necessary files for flashing:
    ROM Android 2.2.1 DDKC1 for Samsung Galaxy Ace (Asian)

    Odin multidownloader V 4.38

    after download extract it using winrar.

    7. Connect the Samsung Galaxy Ace to PC, on ODIN a COM Port mapping will indicate and turn to color yellow if the device is already detected.

    8. If all files is already loaded and the phone is properly connected,.. Hit the "START"/"Checksum Fail"(As in picture highlighted yellow box) button to begin flashing.
    Wait until the whole process completes it only takes around 5 minutes to finish. A progress bar on the left side of ODIN will show you the downloading progress.
