i9300 baseband version UNKOWN and NULL IMEI topic

Hello,


I have a big issue with my i9300. I flashed PDA: I9300UBUGNK1 Brasil version and I decided to root it using CF-Auto-Root-m0-m0xx-gti9300 .

After root the phone was perfectly working, but I uninstalled some pre-installed games which come with that Brasil version from sammobile and after I woke up after several hours I've noticed that there is no signal. In settings > phone info it says BASEBAND VERSION : unknown and IMEI : null.

I tried to flash again, I've flashed different version, nothing can help. The phone is fully functional WIFI works, only no signal, null imei and unknown baseband version. What the heck I can do before smashing it with a hammer?

And I'm talking about home fixes, as I don't have jig & other professional tools

Unkown Error -24 topic

Hi All,
I had this problem with I uninstalled SwiftKey. When I tried to re-install it from the PlayStore I now get this message.
My device is not yet rooted and based on the solutions that I've read, you need to have access to the data\data folder which using the file explorer, has no files most probably because it's not rooted.
Is there other way to solve this issue without being rooted?
Thanks a lot!
