Sprint phone seems to be half flashed to Boost Mobile need help full flashing

[Dreadnought1988]

I bought a LG G4 from my local Boost Mobile shop that was flashed from Sprint. He sold it to me at a very low price of $200 when it was $450 at the time because not even he could figure out why talk/text would work but not data. Wifi works perfect but when I leave my wifi spot or turn wifi off data is non-existent. I bought the phone from him knowing that data didn't work, and at the time I didn't need data, but now I do. It is a cdma phone because I see no slot, after taking the battery out, where a sim card would be inserted. Is there any possible way to get this phone flashed a second time to a full flash from a potential half flash? If so can you please give me a step by step guide, link a definite guide that WILL work, and or, a video that WILL work? Thank you in advance, and hopefully I can get this issue resolved because this phone, although not the latest, is a magnificent mobile device and I would sure hate to have to discard it because I can't get data on the go.

1st of all there is a sim card slot. You were looking in the right spot, by the battery but it's under to SD card slot. Even though it's a CDMA phone data won't work without the sim, and you will only get talk & text. I am assuming there is no sim installed as you would have seen it installed. I would suggest going to a sprint store and getting one (if you have sprint) or whoever you carrier is. A phone is pretty straight forward and ours is no different. There is no such thing as "half flashing" a phone. If you have service but no data then there are only three possibilities: Incorrect APN, profile needs to be updated or no sim. Hope this helps.

Supposedly there is data on it but it is 3g and not 4g and no matter what i do it still wont work. Are you saying if I get a boost mobile sim card and install it in the lg g 4 I will be able to get 4g lte data service through boost mobile?

The Sprint/Boostmobile/Virginmobile sim are on eBay for the G4 and they are pretty cheap.
