A month or two ago, I had bought an old SGH-E900. I plan to use this instead of my current phone (to get away from distractions, you know?)
I had flashed an upgraded firmware (from E900XXFG1 to E900XXFG2 (to remove messages and other data from the device, as the previous owner never wiped the phone)
Yesterday (16/07/24) I had purchased a new SIM Card which the phone accepted just fine. It was able to activate and I was able to make a call. I had also successfully recieved 2 messages. Around an hour later, the device started acting strange. The phone would freeze and reboot itself whenever it sent/recieved messages or calls. Do you have any ideas on how i can fix this? I believe it may have been linked to the firmware reflashing. I can send a video if you'd like.
If it helps:
-I had made a dump of the E900XXFG1 firmware before flashing E900XXFG2. I reflashed E900XXFG1, but the issue still persists.
-I have tried the firmwares E900XXFG1, E900XXFG2, E900XXFF2, and E900XXFF3. All of these are UK firmwares, which matches the device.
-I have verified that the SIM is not malfunctioning, as it works just fine in my old android devices, and my T-Mobile Samsung GT-E1190.
-The phone was boxed, and contained an Orange booklet, so it was locked to Orange at some point (Or still is)
However it accepts my new SIM.
