EFS corrupted? galaxy A520F - GSM-Forum

Hello. Lately I've been having a problem after turning off oem unlock (mistakenly) on my galaxy A5 2017 (A520F) I got the "custom binary blocked by FRP lock" message on boot. After some reasearch I found out I needed to flash stock rom which I did and now phone comes on but despite the sim card being detected I get "Emergency calls only". On typing *#06#, I get the IMEI but on *#0011# it says "IMEI status: NG". Chimmera tools proposed to repair the IMEI for this very model for free on their website but after installing the software on my computerand connecting the phone, it gets detected but no "repair IMEI" option. I'll be glad if anyone could help me solve this issue. Thanks in advance.
