Vinod Nayak 443 Report post Posted July 28, 2013 (edited) Source: Xda-developers Requirements Baseband should be on MDL or MDC If you are on MF9 then you have to downgrade either MDL or MDC baseband. Donwload MDC modem. Use the downloaded MDC file and flash it with Odin to your Phone. Once flashed check if your baseband is MDC. Phone SPC/MSL code. Download SPCUtility.apk Run it, you gotta be online for this to work. Stock Dial ##3424# enter your SPC/MSL and put the phone into DM + MDM + ADB mode. BE SURE TO SET BACK MTP+ADB ONCE EVERYTHING IS DONE. AOSP Connect phone to computer, Enable Debugging in Developer Options. Open command prompt/terminal, Enter adb shell, Type su and press enter, type setprop sys.usb.config diag,acm,adb then hit enter. This mode disables itself after reboot. Download S4-Unlocker this oneclick is developed by meanngreen04 from XDA, be sure to thank him. Password for zip file meanngreen04 Download .net 4.5, this is required for the one click to work. Assuming that your phone is still connected the computer run the S4 unlocker and click on Scan and Unlock. Your phone should reboot, thats it now your phone is unlocked for GSM You can revert back to MF9 baseband again using this modem PLEASE DONATE TO AUTOPRIME from XDA, all credits go to him. even 5$ is something. please do DONATE to him. i have donated.

Vinod Nayak 443 Report post Posted August 20, 2013 SO guys !! Any luck with unlocking yet ? I got a S4 in hand and would like to sell it as GSM/CDMA Some have identified the OTA folder from a unlocked phone. Trying to get a value for a variable. I doubt some one can identify it. Whatever they do to the phone while unlocking through OTA will definitely be encrypted. None of the unlocking have the slightest clue as in how to generate a code till now.
