Hello everyone, I opened a new thread, as my basebands thread was getting out of hand.

What is this?

These files are the stock firmwares, but prerooted. You wipe your phone, flash this using Odin (I recommend this version), and you will have the stock 4.1.2 firmware, with TWRP, SuperSU and Busybox all working, no need for any extra process to root. The files I launch here will be modified firmwares scavenged from Sammobile, as it has been since I was early in Samsung modding, a loyal friend (Like a USB Jig too). I am working with these firmwares as I know there won't come out new updates for them.

Important Notes:

The first boot will always be in recovery (automatically), as some firmwares will patch back the stock recovery. Since I don't know if our phone does that, I decided to make it reboot. Do not be alarmed, click in "Reboot" and select "System". It will boot up properly after :)

These images are the factory stock images, but with built-in root access. You flash with ODIN, and you will have the stock 4.1.2 JB, with root access and [MENTION=5344004]kotzir[/MENTION] 's TWRP, the only need is to update the SuperSU Binaries as soon as you set up your phone. These files will increase the binary counter, as they are Custom OSes. I do not take any responsibility for any damage caused, you are choosing to flash this file and possibly bricking your phone if you don't do it correctly (It worked on my phone, do not get alarmed by this message, it's the procedure to do in case someone messes up and blames me for it :) )

About GT-I8730T:

The GT-I8730T is a different device, which means if I flash these on my phone, I can brick it. Anyone with a I8730T, please flash and report to me if it is working. Thank you :)

Future releases and work:

In the future, as now I am doing some tests, I will release the latest firmware (I8730XWANE1) with I8730XWAMK1 baseband, as this baseband is the supported by all custom rom releases for our phone. With this, it would be easier to return to these Roms, if a user gets tired of TouchWiz :P

Notes regarding Samsung Firmwares:

Most European firmwares, will work outside Europe. Asian firmwares will work in all Asian countries as American firmwares will work in all american countries. A Brazilian firmware will work outside Brazil, if you are still in America. You can be in Chile with the Brazilian firmware and vice-versa. This note is important for users who want their phone unbranded, as I could only find one working firmware for Brazil, and it is branded.

How to know the continent of the firmware?

It's the next letter after the I8730 indicator. D for Asia, U for South America and X for Europe. This is only for our phone, I am not sure if this applies to other phones, but surely has another indicator. If you noticed, Spanish and Swiss firmwares have exactly the same baseband. The only difference is the sales code, which is not important :) Not even language, because in first boot, you get to choose a starting language.
