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.

Hi,
I have Galaxy ZOOM LTE (SM-C105) (not SM-101)
I have similar problem to Galaxy S4 (GT-i9505) owners - no LTE option in phone menu.
I'm 100% sure than phone have LTE because I can install app "Advanced Signal Status " and LTE works.
I flashed with diferemt ROM (oryginal) but nothing happened.
What else can I do?

Got the same problem... anyone can help?
Wyslano z mojego Samsung Galaxy S4 ZOOM za pomoca Tapatalk
i have the same problem,
im with 3 uk, and its not giving me LTE and its not in the settings to select.
but i tried an EE sim (in an EE shop) and YES it connected to LTE and i see the LTE option in the settings..
looking at the wiki/List_of_LTE_networks#Europe
i see this..
3UK for LTE uses
Frequency 800 MHz Band 20 and 1800 MHz Band 3
EE for LTE uses
Frequency 2600 MHz Band 7 and 1800 MHz Band 3
now i know my zoom SM-C105 Flashed with the factory unbranded UK firmware CAN connect to LTE
what do you think is my next move?
could i try flashing with a Switzerland firmware that i see also uses Frequency 2600 MHz Band 7
or am i heading down the wrong path?
---------- Post added at 08:45 PM ---------- Previous post was at 08:41 PM ----------
Is there a 3UK official firmware out there i could try?
and if i found one, would flashing it lock my sp-unlocked phone to 3UK?
useing the app PHONE INFO SAMSUNG i get this...
so, the app tells me under heading 'Orignal csc code: = BTU that we know is UK & IRE (dose the app get this from the hardware?)
and the app says under the heading 'Firmware info:
bootloder c105xxuana1
baseband c105xxuana1
pda c105xxuana1
csc c105BTUuana1 <--- notice the BTU
under os
build number, fingerprint and build dicription all have c105xxuana1 in the text...
we know c105xxuana1 refers to newzeeland and they dont use the 800Mhz band 20 that i appear to need.
so it appears i have UK hardware running Newzeeland Firmware
ideas?
ok more info...
just checking samsung site and this SM-C105 can defiantly do 4G (LTE): 800/850/900/1,800/2,100/2,600MHz
both 3uk and EE use 1800 and as i cant connect to LTE with the 3UK sim, lets put the 1800 to one side....
with the EE sim in, it DID connect to LTE so i guess it used the 2600 band.
only bad left that 3UK use is the 800 band, so ive just flashed the UK Voda FW that ONLY uses the 800 band for LTE
ive a feeing im getting closer but in settings i still dont see LTE
only this...
WCDMA/GSM (auto connect)
WCDMA only
GSM only
im not currently in an LTE signal place so cant test this, but would the option LTE/WCDMA/GSM (auto connect)
only show up when in an LTE area?
Posting this and hopefully helping others.
Yesssssss got 4G today on my trip to london..
not sure if its one of these three things below or a combination of two or all three as i did this steps in a non 4g place and couldn't test for a few days.
1. i flashed the UK Voda software, according to the LTE wiki vodaphone uk only uses the 800mhz band for LTE.
2. installed the app 'Advanced Singnal Status'
3. got a replacement simcard from the 3uk shop. (instant transfer of number to new sim no pac required)
in the 'Advanced Singnal Status' app, tap ADDITIONAL INFO, (on the other firmwares i tried it wouldnt let me in this section, says locked out or words to that effect)
in additional info, tap Device Information. and then i Set 'Preferred Network Type' to 'LTE/GSM auto (PRL)' then hit home to back out.
(NOTE: in the phones Settings > More Networks > Mobile Networks > Network Mode.. there still ISNT an LTE option, even when i was connected to 4G today.)
ive a feeling i would still have to use the toggle in Advanced Signal Status app after a reboot, as LTE still isn't showing up in the phones settings menu.
But ether way im happy. spent most of the day driving so didnt get to test out the 4G but google maps was streaming and my radio app was streaming
lovley, with a sexy 4G logo where i normally only see H+
Hi,
I recently purchased a XT1527 - AT&T go phone and it was working well in USA as I got 4G signals all over.
I am now back to India using Idea network, the phone gives me only 2g network
I even tried *#*#4636#*#* and set the preferred network to
a) WCDMA only - couldn't find any network
b) LTE only - gives me only 2G
c)LTE/WCDMA - got only 2g
I also don't see the preferred network options under
Settings->wirless and networks->more option
how to resolve this issue?
Att model may not have the radio bands you need to get anything higher than 2g. Sounds like your issue with me.

The North American models only have the 3G/4G bands for North American networks. You'll only get 2G internationally.
As a noob, I may not state this question correctly, so please excuse any errors. My Sony Xperia Z5 Compact E5823 (international version) was recently registered on the MetroPCS (T-Mobile) network. The current software build number is 32.2.A.0.224 and the preferred network type selected is 4G(preferred)/WCDMA/GSM.
The phone is located in a major metropolitan city and T-Mobile has accomplished an area-wide LTE Band 12 build-out. The signal strength icon in the status bar either shows a "4G" connection or no connection type of any kind rather than the "LTE" connection icon. the signal strength icon generally shows only 2 or three bars even though, at this moment, the phone is 1/8 mile from the T-Mobile tower at a time of day with little traffic. The connectivity speed generally seems to be quite erratic.
My question is: Do I have LTE connectivity and, if not, how do I get it? An agent at a local MetroPCS agency location said that the ROM or firmware had to be "flashed". Is this correct and, if so, how does a "noob" go about it?
Thanks to all for any responses!
If you installed the settings metro sent to your phone, it might not be an issue with the phone since 4g is LTE internationally. In the US and NA they made 3g+ into 4g and LTE into its own thing as a marketing gimmick. H+ shows up as 4g in the US phones and firmware and LTE shows up as LTE. In Europe LTE shows up as 4g in a lot of handsets.
Youprobably need to try another network on your phone to see if it behaves the same way and I'm betting that it won't. Likely it is the network causing issues and not the phone in this case.
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
I have recently been getting download speeds of over 700Mbs on T-Mobile, so I was trying to figure out if I was using some of the new Sprint Mid band spectrum - Band n41 (2.5 GHz). LTE discovery says it is on band 66, but that seems to fast for 600Mhz (at least what I have been used to which was just like LTE). Any knowledge would be helpful...
Thanks
Have you tried this app? Works for LTE, not sure if it'll tell you the 5G band, though.
