I am new to mess around with mobile phones and Android and (therefore) also managed to bring my girlfriend's GT-I8190 phone to a non-working state. Although there are lots of information in this forum I am more confused than sure what to do. I hope to get here some help / information / explanation.
The phone was bought in Germany and had probably a German firmware. But I do not know, since no connections to Kies or whatsoever and no backups where done earlier. After a error of Android (e:\ failed to mount or something similar) which blocked the phone on the startup logo of the non-modyfied S3 mini, my guess for a quick solution was to flash the firmware with Odin to a new(er) German version. I downloaded (from a German forum) and flashed successfully several versions (supposedly OXA). But with all version the network connection hasn't practically worked. Only very weak and only at a few locations. Once I used in desperation also a so called stock-recovery from somewhere.
I visited a shop where the uber-friendly Samsung service overwrote the firmware first with the general and later with the LaFleur version (PDA: XXAMG4, CSC: QXXA MH1). Kies tells me the CSC is somehow a VE1 version (what country is that code for - moon?). But the problem hasn't changed.
I still have the original IMEI, but I'm missing the baseband and, what worries me more: no product code. I managed to read it out only with "CheckFus" which says only: Not Active1
Since I probably haven't used the right firmware at least once, I am hesitating to do more. My ideas are as following: modem, firmware, baseband.
What is the best way to proceed? Is there still a easy solution? I don't mind to change to another version - no stock firmware is required. Am I close to have a 4" tablet?
Any answer is appreciated - thanks!
