It was a stupid mistake, just messed Odin files.
Sorry to bother everyone...
Dear Dr. Ketan, I'm writing to ask for some help regarding the installation process of your latest rom.
I was already using the version S12 of your creation. Today I tried to install the T03 version.
At 1st I tried to install the rom only with a factory reset, and tried to follow step by step your instructions. As I had some doubts regarding my specific CSC region, I chose not to change it during installation.
Apparently everything went OK, but when I tried to boot into system my device rebooted 3 times before succeeding.
And after that neither bluetooth or Wi-Fi were working.
I try then to do another clean install, this time formatting data completely.
The result was absolutely the same.
Just to check, I tried another clean install formatting data, this time flashing the CSC file. Again, after some reboots the device booted finally but without Bluetooth and Wi-Fi.
Just to be clear, every time I flashed the bootloader and modern through odin as instructed.
I'm sure I'm doing some kind of mistake, but I cannot find what is my error. Can you please give me some advice? Or some other experienced user here?
Thank you so much!!
