    It worked but not I cannot connect to Kies and a couple of the navigation apps are in hebrew or russian.

    What is involved to get back to 4.1.2?
    Thanks guys.

    • androidteen

      Hi, you may need to flash back to stock 4.1.2 firmware. Where do you come from? We might find you a correct firmware.

      • Trev

        Would love any assistance. My country is New Zealand.
        I could possibly go back to an earlier version and then run an update from my phone to get the correct 4.1..2

        • androidteen

          Hi, This is the 4.1.1 firmware for New Zealand Verizon.
 You might go for OTA update to 4.1.2 Firmware after flash back using the above file.

          • Trev

            We do not have Verizon in New Zealand. Is the firmware tied to Verizon somehow? I am with a company called 2 degrees and I do not think they require any proprietary software.
            I would just require an international version that operates here.

          • Trev

            Thanks for your assistance to date.
            Another question – it may sound naive – but is the downgrade the same process as the upgrade,
            Load the file into the PDA section of Odin – as per the upgrade?
            I would imagine it would be the same as the phone shouldn’t care what firmware is being installed.

          • androidteen

            Hi, the upgrade and downgrade shall use the same procedure with Odin. We have a complete tutorial on upgrade or downgrade on Samsung Galaxy S3. We always recommend to use the matching firmware with your device in order to avoid any unnecessary issue. Anyway you can still flash firmware from other country, and change the CSC later.

          • Trev

            I have tried several versions of 4.1.1 and 4.1.2 but none of them work for my downgrade from 4.2.2.

            I get a PASS signal via Odin but the phone keeps going through a reboot cycle. I read somewhere that the reboot should not be ticked in Odin and a process of clearing the cache and another step should be done. Not sure if this is relevant or not.

            I would like to retain my data similar to the outcome of the update process.

            Another thought …. can I just change the firmware version number on my phone to fool the update process for a current OTA firmware download?

          • androidteen

            Hi Trev, first of all, let me clarify the auto boot option in Odin. It works to reboot your phone automatically after flash via Odin. It does not lead to bootloop after the flash.
            We suggest you to backup your data and wipe data before flash 4.1.2 firmware through Odin. Some of your application or system file may not compatible especially you got a major Android version upgrade.

          • Trev

            I appreciate your ongoing assistance.
            I used Kies for backup but since the upgrade I cannot use it via USB. I do have an older backup – once I can access Kies again. The Kies Air is functional but does not do backup or syncing of accounts. If I had those two features back again I would stay with this firmware.

            I am a little reluctant to wipe my data given the problems I have had trying to downgrade. I do have some technical ability but not in this area. When you suggest I wipe the data does this mean that I do a factory reset. I assume this will take me back to 4.2.2 but without any downloaded apps or data.

            Some specific questions.
            1. Would it be beneficial to unmount and remove the SD card beforehand?
            2. Should I be able to run Odin and install 4.1.1 after doing the factory reset? That is just by inserting the appropriate firmware file into the Odin PDA box and running it?
            3. Have others had similar problems with a resolution as suggested above?

            I love my phone and don’t want to stuff it.

            Thanks again to everyone who put their time and effort into this forum.

            The mistake is mine. It’s actually New Zealand Vodafone firmware instead. Nevertheless, I fail to find the matching firmware for company 2 degrees.
