Member: 2625229 Status: Offline Thanks Meter: 0 | Samsung G850F - Destroyed IMEI, I have only cert file I tried to unlock a G850F. The phone unlocked but the IMEI erased from the phone. I didn't keep any nv data backup, either efs. I have only the phone's cert file. How can I restore the IMEI only from the cert file? |

Member: 2625229 Status: Offline Thanks Meter: 0 | I managed to restore S/N from the EFS file created during the unlock. But it didn't contain the IMEI. ---- Cert Write Log: Checking certificate file... OK KEY ID: 0932 Waiting ADB device... OK Reading phone info...

Member: 2625229 Status: Offline Thanks Meter: 0 | Nothing is being showed when dialing this number. As I said, I have no EFS backup (I only have one without IMEI) I dont have also no nv_data backup. All I have for IMEI is a valid cert for my phone. (with correct IMEI and correct imeisign) I have tried other certs without results. I must have a SIM card inside the phone? |

Member: 2625229 Status: Offline Thanks Meter: 0 | Well this method didn't really work BUT... --- I managed to fix it! What I did: 1. I had an EFS Backup, created automatically from Samsung Tool during the SIM Unlock. (This backup was without IMEI, but containing my cell phone's Serial Number) 2. I had also a cert backup as I said in the first post. 3. I wrote this EFS with Samsung Tool 20.5 . The result was correct S/N but null IMEI & unknown Baseband Version. 4. I downloaded Root Explorer, I entered the /efs folder, and deleted the nv_data bin file. 5. I rebooted the phone - the phone booted up with Universal IMEI (004999010640000), correct Serial Number, correct Baseband Version, in other words everything was correct except IMEI. 6. I downloaded Samsung Tool 19.1. I replaced version 20.5 with 19.1. 7. I wrote cert file with Samsung Tool 19.1. The phone restarted with correct IMEI (the original one) and unlocked. I did and a few calls just to be sure. In conclusion, the Samsung Tool 20.5 has some bugs. When I flashed the cert file with 20.5, nothing happened, the phone had null IMEI, and sometimes it went into bootloops. Cert file MUST BE WRITTEN WITH SAMSUNG TOOL 19.1. My firmware during this process: G850FXXU2ANI3 / OLB2ANI1 v4.4.4 (I downloaded 4 flash files as profkefah mentioned) OS: Windows 7 Pro 64bit Model: SM-G850F Android version: 4.4.4 Phone version: G850FDXU1ANI1 PDA version: G850FXXU2ANI3 CSC version: G850FOLB2ANI1 |
