Hi there,
I've got a Verizon HTC One Max. I rooted and put CM12 on my device, and it seems that some of the network bands aren't compatible with this device. After doing a bit of research, I noticed that the LTE Bands supported by this device are the ones used on my Canadian cellular carrier; However, when I select those types of networks to be used on the device, I get no signal picked up. I'm currently using "WCDMA only" as my selected network band for the device, as none of the GSM, LTE, or CDMA options work. It seems that it only picks up the 3G and 4G bands, but no LTE or GSM.
Now I don't know if this is because of the type of device I purchased (like I said, I found a way to get service to the phone through WCDMA), but I was hoping that maybe I could utilize the LTE network in the area instead of using the awful 3G and 4G speeds.
I'm on Virgin Mobile's network, which is a partner network of Bell Mobility Canada. Their supported network bands are:
"Although both are different and independent from one another, both the CDMA and HSPA+ networks use the 850 and 1900 MHz frequencies. Bell's LTE network uses Band 4 Advanced Wireless Services (AWS 1700/2100 MHz) in most coverage areas and Band 7 (2600 MHz) in a few areas."
The Verizon HTC One Max is compatible with the following:
Verizon: 850/900/1900/2100 MHz with HSPA+ up to 14.4 Mbps and LTE: 700 MHz
So looking at this, I might be an idiot - it looks like on second observation, maybe they're not compatible. I figured I'd post this just to double check anyway for good measure. Anyway, if you've got anything to provide, that'd be great.
Thanks.
Hello community!
I have PadfoneX with AT&T firmware, I use it in Russia and Ukraine.
My problem is that I can't change network mode - there is no such option! (KitKat 4.4.2 with AT&T Software)
When I'm in Russia, I can use only 4G - LTE or HSDPA - it's too expansive sometimes when I don't need high speed connection at the moment.
When I'm in Ukraine, I can use only EDGE and only in airport I can "catch" HSDPA - I can't understand why it's so? Provider tells that coverage of 4G network exist in my town, but phone choose EDGE and in airport it switch to 4G.
What is the problem? Can I switch network mode to 2G-3G-4G manualy? Is problem in AT&T software???

If you want to force EDGE, grab "4G Switcher" app from the Play Store and set the "Preferred Network Type" to "GSM auto (PRL)".
As for only getting EDGE in Ukraine, what LTE bands do the local carriers use? The AT&T Padfone X has LTE on bands 2, 4, 5, 7, 17. In Russia, you're probably picking up LTE on Band 7.
THE CONCERN:
Padfone S - LTE signal icon in status bar absent and LTE option in settings absent. Just H, H+, and 4G icon.
MY QUESTION:
Has anyone ran into this same senario and fixed it? Or, come up with a real concrete understading of the LTE bands on PFS WW firmware?
POST ABBREVIATIONS:
PFS=Padfone S (International) model.
PFX=Padfone X (AT&T) model.
H=HSPA=3G
H+=HSPA+= 4G
4G= 4G posibly LTE (That I am trying to figure out.)
WHAT I DID:
So, did a full system wipe and flashed the most recent official Asus PFS firmware on an (AT&T) PFX model with TWRP 3.0
THE OUTCOME OF CHANGING FIRMWARE SO FAR:
Overall, phone works incredibly well. Smooth. No bugs except for LTE band issue. However, I don't know if it's an actual issue.
Flashing to PFS gave me Android 5.0, but most importantly the Padfone Station works perfectly as well Google Play store without having to modify anything. (Both reasons I didn't keep CM12 or CM13.)
THE CONCERN AGAIN:
Concern is that in this PFS firmware, LTE signal icon in status bar absent and LTE option in settings absent. Just H, H+, and 4G icon
WHAT MY PHONE DOES:
Only displays H, H+, and 4G in status bar next to signal strength.
In Settings > Cellular Networks section, only gives me Preferred Network Type option of 2G, 3G, 2G 3G 4G.
No LTE option. Yet, phone specs indicates that it has the bands.
LTE bearer option in APN does nothing.
WHAT I DID:
Downloaded an app called LTE DISCOVERY (Google Play Store), and it shows that when signal status shows 4G icon, it actually is using the LTE band 2. (See Photos below)
BAND 1900 Mhz band 2= LTE
However, it doesn't stay on a 4G Band 2 frequency that long. Usually jumps back to H and H+. And data connection disconnects constantly. I have to disable and re-enable data to get it to reconnect.
Note: My area has a strong AT&T LTE signal, and on PFX firmware LTE worked great. I know the hardware is capable of connecting to network. Just not available on PFS firmware, I guess?
WHAT I MIGHT DO NEXT:
I am considering trying to flash modem image from Padfone X, but am hesitant.
Also considering using an app called Nexus 4 LTE Modem Flasher (Google Play Store) which flashes preloaded LTE bands and helps enable the, but I'm hesitant to use it since this is not a Nexus.
Also considering flashing Official Asus Padfone INFINITY WW firmware to see if that is any different. Infinity also has a Padfone Station.
Has anyone ran into this same senario and fixed it? Let me know please.

That being said, my hardware is capable, but the PFS firmware I flashed is not going to access those frequencies and bands.
Soooo, going to have to flash modems for them somehow.
Anyone successful in this arena of flashing modem to include LTE band 4,5 and 17 on PFS?
...additional photo. APN Bearer options, system info to go with Original Post.
I have a Padfone X flashed to Padfone S running on T-Mobile.
The 4G network indicator in the status bar really IS LTE. Back when Verizon was rolling out 4G LTE, providers like AT&T and T-Mobile didn't want to feel "left behind", so they upgraded their 3G networks to HSPA+ and marketed it as "4G". In the rest of the world, 4G correctly refers to just LTE (and WiMax in areas that still use it). So basically: E = 2G EDGE, H/H+ = 3G HSPA(+), 4G = LTE.
The Padfone S modem contains all of the bands that the Padfone X modem had except for Band 17. On my device, after flashing the Padfone S firmware, I did not flash the Padfone X modems, and I'm still able to connect to LTE Bands 2 and 4, HSPA+ Band 2 (1900MHz), and EDGE Band 2 (1900MHz). To get Band 17 working again (for AT&T), apparently you need to have backed up the EFS partition of the Padfone X via the older TWRP (I'm unsure if Quarx's TWRP 3.0.0 restored this functionality), and restore it once the device is flashed to the S firmware.
Have you tried forcing the phone into LTE-only mode? Download the 4G Switch app from the Play store (icon is a circular red power button), scroll down a bit and change "LTE/GSM auto" to "LTE-only". See how the phone reacts.

First, thank you for your input and advice.
Second, I tried to use two 4G Switch apps (4G Switcher and Radio Switcher) and both open the following same screen. Like if both apps got hijacked by lollipop and only opens a secret TESTING page to Device Info HANDHELD MOBILE DEVICE INFO. This does allow me to select preferred LTE network, but the apps were suppose to have a completely different visual and GUI. Happened to me with MobileUncle Tool and Tool Hero when I went to Engineering Mode > Engineering Mode (Android) > Same Screen.
Why?
...this screen. All four apps send me to this screen. Why is it hijacking the apps and sending me to the Testing page?

That's the correct menu. Scroll down a bit and look for the "LTE/GSM auto" option, press on it, and select "LTE-only". Might need to throw your phone into Airplane mode and back out again for the change to take affect.
It's located a few lines below the screenshot you posted:
In this screenshot, it's where it says "WCDMA Preferred": http://i-cdn.phonearena.com/images/articles/64301-image/Phone-info-1.png
Change that to LTE-only. See what happens.
Hello,
I am trying to find out the way in which I can able to activate the "Service Menu" or Engineering Mode" for LYF Wind 4, Handset from Reliance Jio, supporting LTE. I need this to change the LTE band to Band 40, which might result in better DL/UL speed for Jio, as the speed presently is really poor, under the "Welcome Plan".
Any Suggestions?
Its bad for everybody mate. Just try doing an reset APN. Thats seems to improve the speed. But its consistently fast only at night. Band 40 is also TDD band so effective bandwidth goes down with number of users. Only FDD bands can give us consistent speed because each user doesnt share the band with another but get his own dedicated one instead.
Got a sprint varient. After now 2 days of searches and reading trial and error.
My g5 sprint gsm unlocked. No matter how i select radios gsm gsm/cdma lte auto everything.
I'm picking up band 5 lte tower. I verified these readings with a att s6 edge.
randomly hpsa and very rarely a gsm network but g5 does connect to all same bands and netwroks as s6 side by side in lte discovery.
On all my att phones on lte discovery primary is lte band 2. G5 wants to default to band 5.
It did connect to band 2 for a few min with great signal might i add. Secondary connection is live on in lte discovery on s6 edge with gsm and network info listed.
Now again my g5 is on 1st lte band 5 most of the time and the 2nd connection is rarely picking up but has switched a few times between hspa and gsm just like att phones info in discovery. but usally sitting here with gsm and a n/s
As my g2 g3 g4 all were sprint on att no problem I didnt figure the g5 would be any diffrent
This seems like a connection and band priority issue not a compatibility issue.
Am i missing something? i cannot find band priority in any hidden menus. Or did sprint and lg take away some of the versatile sprint radios functionality?
sorry for being long winded
Its just weird. It will make calls,text.mms,internet all on 3g 4g and lte. But signal keeps dropping. While it continueously switches from lte to 3g band 2 and 5 Does not drop calls. Sometimes i have to make a call a time or 2 to get connected to the network. Texts seem to be coming through on time.
thanks in advance guys
from what i need i gotta either set band priority or find setting for lte/gsm/umts which i cant find
i am also getting too low reception
