Hello guys.
Just few months ago I got an used S3 T999 (T-Mobile). I didn't know so much about how to change the ROM and also root the cellphone, but I found a lot of info in this forum and I learned how to do it. First, I noticed that my S3 had an update available: 4.3 JB (The stock one). When I made the update, few days after I changed the ROM (installing it with the CWM recovery, of course): the CyanogenMod 12.1.1 (http://forum.xda-developers.com/gala...msung-t3055048).
Since that, I've been using that one and I haven't found problems. But really, I thought that I can unlock the cellphone whenever I want with an app that I heard months before I got the cellphone. I tried that one and few more ways but I can't make it... GalaxSim Unlock, Galaxy S Unlock, the code with the phone dialer... Nothing. I've been finding in the whole internet and the only thing I found is: My S3 T999 isn't compatible OR It has to be on 4.1 Stock Version.
When I found that Info I tried to do a downgrade. I were lucky that I didn't brick my S3, because I read about doing a Downgrade when you upgraded your S3 to the 4.3 JB version and the EFS Folder V2 and V1 (about the baseband or whatever). Also I tried to downgrade from the CyanogenMod 12.1 to 4.3 JB and I made it, but I can't make it with an older version and try those ways I said.
If you need more info to make an answer: Yes, I made a backup to the EFS when I made the Upgrade to the CyanogenMod 12.1. YES, my S3 is totally rooted. YES, I installed the correct ROM for my cellphone in all cases (the same baseband).
Now (as I said) I have:
- CyanogenMod 12.1.1
- Baseband: T999UVUENC2
About ODIN mode info (I don't know if you need this):
- Warranty Bit: 1
- Bootloader RP SWREV: 1
- Qualcomm SecureBoot: Enable
- Current Binary: Custom
- System Status: Custom
- Product Name: SGH-T999
- Custom Binary Download: Yes (12 counts)
I'll be grateful if you can help me with this. I can't use my network because I'm not T-Mobile User.
Beforehand, thanks.
