Ran into some issues with a new phone, hopefully someone can help me out. I've been reading and tried a few things, but no dice. I purchased an unlocked AT&T Galaxy S3 off Ebay, then proceeded to install CWM recovery, take a nandroid backup of stock (v4.0.4), and installed CM 10.2. Upon inserting my T-Mobile sim card and trying to configure the phone, it complained about me needing to insert a sim card and I subsequently noticed that both my Baseband Version, Network, Mobile Network Type, My Phone Number and IMEI are reporting as Unknown.
I've tried restoring my nandroid backup to stock, same items are reporting as Unknown. Trying to flash several stock images with Odin results in 'SW Rev Check Fail: Fused 2 > Binary 0'. I'm guessing this is since CM 10.2 is v4.3. I've tried using NV-items_reader_writer to read/write the IMEI, but it won't connect, complaining 'Phone does not accept SPC. SPC is not correct.' I've run Triangle Away under CM 10.2 with no change to Odin results.
