[Completed] No LTE on boostmobile with Samsung Galaxy S4 - XDA Assist

Hello all,
First time poster here so hoping to drop this off in the right place. I have a brand new (out of the box) Samsung Galaxy S4 which I just purchased from my Boostmobile dealer the other day. Installed the latest Cynogenmod on it only to find that LTE did not work. 3G works fine but this prompted me to look around for help. After discussing in #SGS4 on freenode, I wiped the phone and installed the latest Optimized cm 12.1 build. Again, same problem. LTE does not work and 3G does.
Model: SPH-L720
ROM: OptimizedCM-12.1-20150817
Carrier: Boost Mobile
Something tells me my problem relates to the carrier?

Hi, thank you for using XDA Assist. I'm assuming you didn't have this problem on stock? It could be adb issues with cm. But I'd ask your question here, http://forum.xda-developers.com/showthread.php?t=2374543. They are the experts on your device.

The only Roms that are designed to work with your device are as listed in Verizon Galaxy S4 Forum Rom List.
http://forum.xda-developers.com/galaxy-s4-verizon#romList
If you really want to see which of these roms work with ATT Sim then you may pose the question in
Verizon Samsung Galaxy S 4 Q&A, Help & Troubleshooting
Only as a last alternative, you may post a very specific question regarding the International issues and incorrect Caller id on ATT Forum AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshooting Make sure to explicitly mention you have the Verizon variant.
Last but not the least, DO NOT flash ATT S4 firmware to your device via ODIN. This will hardbrick your phone and make it completely unusable.
If you cant tell im new to this forum. I appreciate the promptness and will do so. Thanks again

[Completed] Galaxy S4 SCH-R970C firmware questions

So Samsung has released Android 5.0 for all the Galaxy S4 units except for one. The SCH-R970C, which is the Cricket variant of the model.
This is extremely annoying for me, considering I have that model Galaxy S4, and would love to get it updated.
Long story short, can an SCH-R970 official samsung rom work on an SCH-R970C? The SCH-R970 is the US Cellular variant.
I don't know if Samsung/Cricket will ever release it for my model, I've been waiting 6 months for it to land on my phone, but I get nothing.
I have tried rooting and putting non-samsung roms on my S4, but there have always been problems no matter what rom I install. Most have battery issues, with it draining much too fast. Others have wifi issues, but that's probably because the rom didn't support my specific model.

[Completed] Rooting SPH-710T

I have a Samsung Galaxy S3. The carrier is Virgin Mobile. They are on the Sprint Network. My model is the SPH-L710T. The build number is KOT49H.L710TVPUOAOF2. It's currently running Kit Kat 4.4.2.
I have seen/read a successful rooting protocol for the SPH-710 but none for my particular model.
If anyone can point me to a successful rooting protocol and ROM for my particular phone, I'd be most appreciative.
Thanks in advance.

Hello and thank you for using XDA Assist.
As you may have already found out, there is an XDA area dedicated to the Sprint Samsung Galaxy S II at http://forum.xda-developers.com/galaxy-s3-sprint but not everything there applies to the SPH-L710T. I suggest you post your question with all relevant details there where the experts familiar with your device might be best able to guide you. I also see a number of references to your model from a site search a thttp://forum.xda-developers.com/sitesearch.php?q=SPH-L710T which might be worth reviewing.
Good luck!

Now we need to buy an unlock code for this and all the sites asked country of origin and carrier. Is it still UK or Luxemburg? Also pls reccomend a trustworthy unclocking service if you know.
Thank you for using XDA Assist.
I see you asked your question in the Android Q&A forum.
You should actually be asking your question in your device specific forum located here
As far as recommending some one for the service we do not do that here on XDA, but you can always read what other users have done in the section.
Good Luck

Erased OS on S6

Hi! So here's my problem folks!
A friend of mine told me he could root my Samsung Galaxy S6 (Telus - Canadian Variant) for me as I didn't have the time, although I have rooted phones before. BUT, he did not successfully do so. In fact, when I start the phone up, what I get is a TWRP load up screen I have gone through the settings in the TWRP menu and found a section where it says "No OS installed!". How do I fix this? I don't know which os to reinstall, or even how to do so. All I can tell you is that it's a Samsung Galaxy S6 that was originally on the Telus Network (Canada).
HELPPPPPPP!!!!!
Thank you!
