I got a bricked Note 3 SM-N9005 from my brother and managed to make it boot with an OEM FW 4.4.2 from sammobile. Before that, the phone was freezing all the time and with null IMEI / unknown baseband.
Now it boots and was working fine until I tried to root with the Autoroot ODIN flash able file from the forums here.
The phone now boots, and works fine until I connect to wifi. First network that is connected works fine, but if it disconnects or if I try to connect to another, wifi gets greyed out and I'm only able to use it if I do a factory restore. Flashing the OEM rom is not working. I get the same problem.
Any fixes? Thanks
