[Q] AOKP, firmware, and SIM questions
My Samsung Galaxy S3 broke when it fell out of my pocket during a rollercoaster ride and now I've inherited my dad's old S2. I just have some questions about flashing roms. I'm planning on AOKP mr1 Milestone 2 on it and I was wondering if I need to update any firmware before I do (currently on stock touchwiz android 4.0.3). With my s3, my phone went into bootloop because I didn't update the firmware before I flashed CM and I didn't want something like that to happen again.
Also, I have a question about my phone not recognizing my new SIM card. I've put my SIM card in my brother's HTC HD7 and it worked perfectly fine. I put his SIM into the s2 and its works. Is there a reason why its not working with mine?
