If you dont have original efs backup files and you already did "Wr.Default EFS" you cannot write original imei. You can try as follow way if you didnot do "Wr.Default EFS" before. 1. Flashing with 5.0.1 (I9500DDUHOA1) 2. Check imei is working or not 3. Backup SuperIMEI 4. Downgrade to 4.4.2 5. Restore original superIMEI Best Regards GsmBest Team Last edited by EmeGSM-Wei; 04-11-2015 at 14:21. | |
