Figuring i9300 original firmware

[philosobear]

How do you figure the android's original firmware?

I have a Samsung Galaxy S III, i9300, the international version. I modified its firmware long time ago without backing up the original firmware.

Since Samsung has updated its devices with newer versions recently I have decided to go back to the original firmware so that I would be able to update my device via Samsung Kies but it keeps telling me since the firmware has been modified updates are not available for my phone.

I have access to MEID and IMEI numbers and probably some other numbers that are listed on the same page.

Is there a way for me to figure out what was the original firmware using those information? I purchased it on ebay and the seller is not listed anymore so there is no way for me to ask the seller.

Even with flashing a new rom, Samsung Kies still tells me that it won't update it because of firmware modification.

When I go online on SamMobile it is showing me different versions of i9300XALE8 or i9300ALEF but how do I figure which one was originally mine?

Thank you.

you can force kies to update your device. be advised that if you ever used a rom with an mg4 or mg2 modem or newer that you may not be able to connect to your mobile network after upgrading through kies. to force an upgrade you need to start kies with your phone not connected to your pc. next go to firmware upgrade and initialisation. enter your serial number and model number. put your phone in download mode and then connect to pc with usb cable . kies should then upgrade your phone to the latest firmware for your region. If you lose network connectivity or have an issue with imei. you may want to flash an mg4 or mg2 modem. this should get your network back.

It keeps asking for the model number which is: GT-I9300 and every time I enter it, it rejects it and says: "please check the serial name and enter it"

If You are sure that you have GT-I9300 then load the newest Firmware for your Region from sammobile and flash it via odin

I purchased it via ebay as an international version. There is no way for me to figure what region it belongs to. The only thing that I remember is that when I got it, and started it, the default language was French which is being spoken in many countries.

When I go online on SamMobile it is showing me different versions of i9300XALE8 or i9300ALEF but how do I figure which one was originally mine?

You don't need the original for the device. You can just use the latest for your country / region.... then get updates locally.
