Compliments for your forums. It's a very great work that you are doing here!
I hope it's not a duplicate topic. If it's so, my excuses for that!
I've downloaded that program Kingo Root V 188.8.131.521, to unroot my S3-mini which have the rom I8190XXANC2 Vodafone Italy
After I started the program and connected the device, I had a doubt, so after few seconds that the program was communicating, I turned off my router, so internet was unavailable.
Then I had to wait 1 minute more till the program said that my device is unsupported, anyway it asked me to press the button "ROOT" .
I did nothing, then I closed the program and disconnected the phone.
Now searching with Google, I found out that this program may harm in some ways, so now I am worried, maybe I shouldn't but hehe you know....
The phone doesn't seems to have new apps installed neither to act weird, so now I ask myself, was able this program to modify or install something in the phone?
Either this answer is positive or not, at this point I would like to do what was my intent: Reset to default, unroot just this ROM version without remove anything (unwanted Vodafone apps), only unroot it and add the Supersu APP; nothing else. Then I can decide later what to keep or what to remove.
I searched a lot in your forums before write this topic, but I found only an extreme "tweaked" version, which isn't my goal.
Another thing that I don't understand is why I see more than one files to flash in the device, seems like it's the operating system, the modem binary, and the kernel? I understood well? It's obligatory to upload all three? Which sequence order?
You mention some applications which helps to upload the roms as like Odin, twrp2.7, I may be wrong, but don't seems that you have a specific topic or an updated download section. I am afraid to search in Google and maybe find some fake versions around with includes malware.
Sorry for all that questions, but I am very new to this Android world. To start for good I need some guidance. I hope you can help me somehow.
Thank you very much.
