Hello to everyone.
I hope i have posted in the right section.
I need info regarding the following situation:
i have a I9300 wich had 4.1.2 and was unlocked by software because it was EFS V1.
Because i didn`t made the proper digging i updated it to the original firmware af android 4.3 with Odin.
After flash i gor the unregistered sim network...because the EFS updated to V2. afterwards flashed again to 4.1.2 original and tryied to unlock using root,busy box and galaxsin unlock but due to EFS V2 didnt work.
Unfortunately i didn`t made backup to EFS V1 before update and now the IMEI shows 0049 (test imei).
The question is: the only way to solve this issue is going to a service center, recover original IMEI and unlock by Imei using pro tools or there is another way?
Thank you.
