3g data only. No LTE.
Hello all, I've been trying to get this google play edition (GPE) ported ROM working with all radios. Currently needing help enabling LTE on my sprint HTC one m8. I hope that this is the right place to go for this.
I first started out without cell service -- no calls, texts, or data. So, I created a backup of my GPE ROM with TWRP and I flashed my phone to the stock root ROM so that I could use the hands free activations from sprint. That worked and I was able to use LTE and make/receive calls.
I then restored my GPE backup. To my joy, I was then able to make/receive phone calls and text messages! Unfortunately, I could not use my cellular data. I later enabled 3g data after mucking around with the settings in the "Phone info" menu that I access via the secret phone code *#*#4636#*#*. All I had to do was change the setting "Set preferred network type" to "CDMA auto (PRL)". Later, I realized that I could also enable 3g in settings->more->cellular networks->preferred network type->3G.
I am still not able to use LTE! I can see that I am able to connect to LTE system but not get data transfer. Please check out attached pictures. I can connect to band 25 frequently and I've also seen my phone connect to band 41 once. Don't know if that helps. Also, I installed Sprint_M8_6.20.654.3_blobs.zip thinking it would help. I have the non HK version and that zip is label with the HK firmware name but I noticed that the blob zip contains only lib files that are added to the file system. I thought it okay to try it out. Unfortunately it didn't help enable LTE.
Has someone had this issue?
