CDMA Android phone on LG U+ (Korean network), WiFi problems, caused by network?
I'm in the UK and I work in the gadget repair industry. I have been asked to sort out an LG Optimus Big LU6800 that's having problems with the Wifi and Bluetooth. It's locked to a South Korean phone network called LG U+ (No Sim card)
After a couple of hours of research (which has been difficult given that there's not much English documentation or discussion on this phone) I think I've worked out that LG U+ have the phone locked down so that the WiFi and Bluetooth functionalities don't work unless you purchase a data plan with the network. I've also read that they blacklist the phone if the contract plan is terminated, also rendering Wifi and Bluetooth unusable. Is this even possible, or is this what they might have done?
Can anyone help me on this? Or can anyone fluent in Korean do some Googling on my behalf to find this out. I know it's not a hardware problem as I have already replaced the antenna to no avail. (this is my first experience with CDMA phones, I've never seen one before). I can't even boot the phone into developer mode, it seems like they've locked that down too .. meaning I don't actually know how I'm going to go around sorting this phone out.
Hopefully someone can help me, this seems like a good forum.
