[Q] unknown baseband version, empty hardware version
Here's the story
1. this phone wouldn't boot up after the OTA update, the screen read "firmware upgrade encountered an issue.
please use software repair assistant & try again."
2. used odin 3.09 to reflash pit and the latest nc4 official firmware (I know it can't be rooted, but that's the only choice I have).
3. phone came back alive, worked for t-mobile and verizon sim cards.
after a few hours or maybe a day, or maybe a restart, phone won't detect sim card, baseband version shows unkwown, hardware
version is empty, imei, network, MIN, PRL version, ERI version, imeisv, iccid are all "unknown".
What I have done:
phone will be back to normal if I flash the firmware again, I've use odin 3.09 and kies 3 many times.
I also tried flashing different modems, for ex, MI9, MJE, NC2 even NC4. But phone will keep restarting, sometimes the phone is working after
a few restarts. But eventually I will have the same problem again.
I was wondering if someone could point me to the right direction?
