Can the OP5 get support for this band via a firmware update as the SD835 is capable of 600MHz?
Does anyone know?
I have a feeling that even with the firmware upgrade it won't help. It reminds me of what was found in unlocking the OnePlus One's LTE bands (for band 12 access). If there's not an antenna hooked up then even with the band unlocked it's unusable due to no antenna. That's one reason we don't have native FM support is the FM antenna pins aren't hooked up.

so many of you have probably enabled your 4g LTE chip on your device but when i try the trick it doesnt work. after research i found that australia uses a different band of LTE to what the nexus can use. a friend of mine suggested that i root and flash a custom radio that works on the australian bands so i can enable LTE. Does anyone know where i could find this radio and/or if it actually exits? and if it does how do i use it?
Hi,
Can't recall where but somewhere it said it only has physical support circuits , I think amplifiers, for one specific band to support LTE. That would mean its not possible without he mod to utilize another band for LTE.
Cheers

There is no LTE chip in the Nexus 4, band 4 AWS LTE (1900 MHz) is natively supported by the processor, and is the only LTE you can connect to. Check and see what frequency and band LTE is in you area, if its any thing other than band 4 AWS 1900 MHz you can't connect to it no matter what you try and do. Google also fixed the LTE exploit in version 4.2.2 so you would have to either roll back to version 4.2.1 or use a ROM that supports LTE, they say so in their description. But again check to see what frequency and band LTE is in your area as that's what will decide for you what you can do.
i need the band 4(aws) but the XT1642 just have LTE bands 01/05/07/08/19/20/28
have any way to change or chose the bands? or its hardware
Thanks
I am also wondering about this. Someone please give it a productive thought.
Any ideas on this? I've read about this method http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 and it should work with the Qualcomm Proccessor of the Moto G4 plus, but I don't know the code to activate the Diag.

There are limitations because of the hardware bits (RF amps) that are missing. For example if the radio works on LTE band 17 (DL 740Mhz, UL 710MHz), then it might be tricked to work in LTE band 12 (DL 737.5MHz, UL 707.5MHz), they are "close enough" to work.
Also I had a Alcatel phone that was sold by T-Mobile with one of the existing bands (LTE 5) de-activated because it was not used by T-Mobile. After unlocking the phone (legally) it would still work poorly on AT&T network - and then I was able to activate that band by using the above software - because the needed RF amps where already present inside.
LTE band 4 AWS is a special animal, the DL and UL frequencies are VERY far apart. Not matching anything else, so even if we can program the radio to work in those bands, the output RF amps will just not be able to perform.

I'd love to say that I understood you but I'm very ignorant about bands and frequencies.
I read that the QC SnapDragon 617 has a X8 LTE Modem (can't link because I'm new, but it's on the QC webpage) which has the Snapdragon Global All Mode, and it's supposed to support band 4 AWS. I don't know if that helps with the output RF amps, or I'm totally doomed.
Yes the X8 Modem supports the bands. But it needs something else to work. Those bits are soldered on the US version and not on the EU one. Similar, on the EU one there is band 20 that is not present on the US hardware.
Hello to all,
I have a ZenFone 2 Laser (ZE500KL). Asus support said me that is a Taiwanese version.
The issue is that is not working with LTE network in my country, only with 2G and 3G. Here is used AWS1 that is the same AWS band 4 (1700/2100 MHz) 1700 for uplink and 2100 for downlink. Asus support said me that I have nothing to do since is a hardware issue because the antenna doesn't work in 1700/2100.
Is there a way to know if this handset could be enabled to work with LTE AWS Band 4?
Thanks in advance for any help.
Regards
First thing first, I'm sorry if my reply did not help you, and this is based on my limited understanding...
Simple answers would be nothing, nothing you can do if this is "hardware" limitation as asus told you.
Now the explanation, note that I'm not knowledgeable about this thing, so I don't think could give a meaningful explanation.
From what I've read, LTE, on different country use different band (1700, 2100, etc). And by that, just say *not the real reason, just play along with it*, "device built by limiting hw capabilities to certain band, to work on region A, because that device didn't meant to work/used outside region A" . This might the reason, you could see asus with WW or TW variant. They limit the device hardware to work only with certain band range.
This is hardware, not software/firmware (if you compare it to like some "unlocked provider device") . So you can't do anything about it.
This is like, using CDMA phone with GSM card, they work at different band. AFAIK it didn't work, cmiiw.
Oh, IIRC, old phone (before Android born) mostly have triband (GSM) you might won't be able to use your device outside your country. Then, newer phone, till now, use quad band to support usability around the globe. cmiiw
I hope you get what I'm trying to say there~
I don't know what it mean about LTE aws 1 / aws 4, I don't think this is just band length (1700/2100).

Since owners of this unit struggle with the non supported LTE bands in the USA, has anyone contacted the modem chip manufacturer “Winlink?” Ask them to provide us with a patch to enable all the bands we need to make our units work correctly in the states?
The only band from T-mobile USA that works is the 1900, very limited 3G coverage but it’s mostly 2G.
Forget all the hacking and reprogramming, don’t you think the chip maker can enable it? Or is this Android related problem?
What are the specs can of the broadband modem from winlink? Are more bands supported in the radio hardware?
So it looks like non of the international S10 models will have support for T-Mobile's Band 71 (600mhz)... This isn't a required band to make a connection to LTE, but apparently this frequency will be utilized as a range extender, and for better wall penetration (indoor connectivity). Seems pretty important...
Is it possible to add support for this band via firmware? Or will there be a hardware limitation?
T-Mobiles lists all their LTE bands on their site as follows; 2, 4, 66, 5, 12, and 71
ALSO, does anyone have any information on where exactly this frequency will be used in the US? Is it really all that important?
Thanks!
