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.
One of the mods linked this snapdragon based band unlock on the front page.
It's a thread for a sony phone, but it's claimed that this will work (or should work) with any snapdragon chip with root. Has anyone tried this or attempted any similar methods on the LG G3?
I'm interested in the 1700mhz umts (hspa+) (aka AWS band), i'm guessing since the tmobile G3 and the wind S5 both use the the same s801 and have the same AWS band i'm after makes me assume this is probly a software limitation or what do you guys think?

Hello I have a problem with my LG G2 (D802) Europe model! My carrier have relase 4G in bands 38B 2600 MHz TDD buth lg g2 d802 not have this bands, has instead bands TDD 40B 2300 Mhz!
I can add this bands on my g2?
The new license the company in 2600 MHz band (TDD) has been acquired by a process of transfer of RCS & RDS and 2K Telecom, with the agreement of the National Authority for Management and Regulation in Communications (ANCOM).

Thank you in advance! And sorry for my bad English!
Unfortunately these bands are not something we can add/remove but some chips are hardware capable only that they're restricting them for some reasons.

Try to follow the clip above if you are from RO(the guy who made this wrote the instructions in romanian), should give you what you wanted but apparently everybody is still complaining about band 38 not doing much
I'm also in the same situation, i keep finding stuff that leads me to think that it's possible, first of all the snapdragon 800 supports LTE band 38, there are several threads that have unlocking guides and claim in the first post that several devices have been unlocked (I did not manage on mine unfortunately).
From what i've seen the One plus one has managed to unlock that LTE band, a Galaxy S5 and several phones that have MTK chipsets (with only root access and an app).
So unlocking LTE bands is not impossible (if there is hardware support of course) .
Really hope someone will give us some useful info on this. (we got 4g and extra 10gb of traffic for free, but only on 4g)
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).

hello, just wondering if i can change 4G bands on my Motorola 4G Plus (XT1642) i cannot use 4G on USA or Mexico, only 3G or H+, i was checking on google and saw something to change baseband to unlock all bands or something like that, can some expert tell me if this is possible or not?? here is my Phone Information:

Thanks for your help
Just wondering if I need to change the Modem file or something to make it work on another country as 4G
Same issue in the Netherlands with my Moto Plus. No 4G only G3 or lower
the weird thing is that no one knows if this is possible lol, no experts yet for moto g4 plus
Or it has multiple bands and it's unclear what you want to change. It has Edge HSPA and LTE for GSM and evdo and LTE for CMDA. That makes it a true world phone. Unless your variant does not support it.

Do that and you probably wont have service at all. I don't think anyone has been able to unlocked bands.

did you flash the nougat test build?

No it's still stock android, though if i use my Galaxy s5 4G pops up immediately
Did not see any reason to use custom rom jet...
Got it fixed, call your provider and ask to reset QOS / data. 4G pops right up after restart.
For those wondering: it's not possible. One can technically unlock additional bands following QPST tutorials, and actually changes does stick, however model number cannot be changed which is the one that "tells" the device which bands to use. This has been my personal experience
It's not that. You can unlock the bands with QPST, but if the actual RF amplifiers cannot work on those bands, you won't get signal. One can be lucky if for example adds 800MHz band to a device that already has 850MHz, but the signal strength might be lower than expected.

I did "add" via Qualcomm software the EU band 20 to my US phone that had band 5, and I will be able to test it when I get there next week. The US phone has the other main two EU bands (bands 3 and 7, urban mostly).

So you're telling me there's a chance? I do have a XT1622 which has bands 1(2100), 3(1800), 5(850), 7(2600), 8(900), 19(800), 20(800), 28(700), 40(2300). I'm trying to use it with band 4 (1700/2100), what should I try next then?
Band 4 is "special" because it has such a wide frequency difference between uplink and downlink that I doubt it will work. The UL for band 4 is the same like band 3, but the DL for band 4 is more like band 1.
Not sure if they can be "coupled" like that, it might... Qualcomm modem reprogramming - to get in that mode it's easy on our phones, Power on + Vol Up and then scroll to Qcom... You need the special software (2 pieces, both running in the same time on PC), don't ask me how, just search on XDA.
