I had an Axon 7 that worked on 3g on México. I did the update to Nougat with the EDL and I lost my connectivity, after switching back to chinese firmware I noticed the extra bands that allowed me to get 3g were missing and now I only get 2g, Is there anyway to add the bands again?:silly:

So the thing is, a month ago my note 4(6.0.1) for some reason stopped working in 3G or 4G.
Things I've done in order to fix it:
- factory reset
- updated to the latest baseband
- changed sim-card to latest possible
- changed carrier
So right now I'm using a different carrier and have 4G and 2G, but when I switch to 3G, for some reason I can't use internet at all.
Is there a possible fix for this issue? Can this be a hardware problem, considering that 4G and 2G are still fully working?
Also, during 3G usage I've checked service mode menu and it says GMM State: Limited Service.
When I use 4G or 2G, it doesn't show this.
What can this possibly mean?
thanks
Hello guys,
I have an Axon 7 A2017, the Chinese one, I unlocked the bl, rooted and flashed B29 rom with the a2017 bootstack, so everything is working. BUT... I can't seem to get GSM reception, I can call and receive calls if I have good 3G reception, but once I step out of the city, my phone become an iPod touch... I'll link photos of my phone on Network guru I you guys can be of any help. I forced the phone into specific bands in order to test LTE, HPSA UMTS and GSM separately, you can see that the phone gets the signal of the GSM tower on both 900 and 1800 bands, but doesn't " translate " it into an actual GSM working signal, that is just my supposition I don't know what's really going in there. Hope you guys can find out what the problem is. @DrakenFX @tenfar
P.S : When I first bought the phone it had the Chinese B10 version, and the 2g was working, weak signal due to prior updates but I could read it. The main purpose of me flashing into US rom was because of an update which enhanced the signal on A2017U.
Signal Reception Comparison
My Axon 7 vs my Samsung S5 in the same spot.

Anyone know how well the H870DS version works on T-Mobile network?
I'm using on TMO and it's working well.
I am accessing 4G LTE over band 12 so my signal is comparable to a TMO branded GS8.
Some things to consider:
1) No VoLTE (that I'm aware of) calling
2) No WiFi calling
Small Annoyances
1) Network mode resets to 3G after reboot, manually selecting LTE after reboots
I have the same problem with no WiFi calling, need it for work too :/
Hi guys,
Recently bought a used(6 months) OnePlus 2 - 2003...I was really satisfied with the performance and huge 4gig ram. I use only a single sim, which has 4G. I used the sim with a Nexus 5 until the phone die, but I have never had any signal issue with that phone. In y country not every area has 4G coverage. I currently have Oreo resurrection remix rom, latest build. In my home town 3G, 4G coverage is at it's best and even on 3G coverage I got decent amount of speed with Nexus 5.
The problem is OnePlus 2 doesn't give the slightest speed that H+ is capable even while I'm on 4G. speed is about 500kbps max with 4G. If I chose WCDMA Preferred, from the service menu, it does show H+, but I can't surf on the internet. I'm very disappointed with this phone now. If I were to go to an area with no 4G, It won't get data connection turned on no matter what I do. I even flashed latest OOS 3.6.1 firmware but no luck. I went back to OOS 3.6.1 and it's the same, cant' switch to 3G data.
Man I don't know what to do now, I don't get wifi all the time when I'm away from home. Is there any way to disable 4G and just use H+ or 3G?
I even changed the band in service menu (*#*#4636*#*#)
Also flashed the latest lineage 15.1, CM 13 and no matter what I do
I also tried couple of other sim/ISPs but no luck
Please Help me
Use Network Signal Guru app(root needed). In app, select LTE band lock and deselect your LTE bands(depend on your carrier) use for 4g and exit. It will prevent your phone from connecting to LTE band. Enable the band again to get the LTE.
