[Completed] Increasing the supported bands or frequency on Chinese phones? - XDA Assist

Hey all,
So I recently have been looking into Chinese phones and have realized that there are some great competitively priced phones on the market, in particular I am interested in the Lenovo Lemon k3. However I have T-mobile, which support Bands 2, 4 and 12 for 4G LTE, most Chinese phones however do not support those bands. I was wondering if its possible to root and then mod any of these phones to support all Bands, I dont want to buy one and be stuck using 2G coverage.
Thanks,

[Q] Use LTE of an American Android Device in Europe

Hi guys,
I bought a Moto G LTE (XT1040) in Colombia because my old phone broke there. I thought there'd be no problem using its LTE capacities in Europe as well. Bad luck. It doesn't since in Colombia/America they use different bands. Is there a way to make my XT1040 use European bands, just like the XT1039 (European Version) would? HSDPA+ works fine.
Some facts that might help:
The phone XT1040 only takes bands 4 and 7 (at least it says so on the box).
According to my provider, I'd need bands 7 and 20. But 7 isn't in use here in Germany yet, and in cities hardly ever will.
I haven't been quite successful in the Moto G forum here. But maybe it's also a rather general question that applies for other Android Devices as well. If I posted in a wrong forum, I'd ask the mods to move that thread accordingly.
Thank you in advance for your help.

[Completed] Can I manually add mobile network bands to my phone or make it think it's another mod

I purchased the lenovo A808t because of it's ecxeptional price vs functionality. The problem is I bough it whilst having seen the specs to the lenovo a806 apparently. They seem to be identical except for the mobile network frequency bands, which means I can't use 4g or 3g in the netherlands. Would I be able to hack my phone and add the frequencies or make my phone think it's the a806? Or are there hardware limitations?

[Completed] ZUKZ1 in Canada (4G)

So i am considering buying this phone, but I have only 1 concern about lte on this website: http://www.gearbest.com/cell-phones/pp_230088.html it says that 4f bands are only:FDD-LTE 1800/2100/2600MHz, so will it work in Canada?? I checked http://maps.mobileworldlive.com/ and It only compatable with 2100, no 1700 is it fine if I only have 1?

[Completed] Problem with lte on my xperia x

Hello,
I'm actually from Germany, but i find this forum very useful..thats why i hope, you can help me with my problem.
I purchased a Sony xperia x online. Everything works fine except the LTE. It's very bad and unstable. I used an iPhone 6 plus before and there was no problem with lte.
I checked every setting, but everything seems fine.
I checked with the app Lte Discovery which lte band the device uses for lte connection and it said band 20. So i can be sure it has the Lte band 20, can't I?
I also found out on xpericheck that the installed firmware is for devices from switzerland.
So I want to ask you, if it's possible that the device doesn't really support band 20 because it's from another country? I haven't found any model of the xperia x online, which doesn't support lte band 20.
I would give you some screenshot but the forum doesn't allow me to do this.
Thank you in advance

LTE band change for J327u Exynos

Hello everyone. As many of us first posters here, I have a problem:
I've bought an north american J327U from someone I know, and that person only used it at home with their wi-fi. It's got an Exynos chipset, and no support for the LTE bands from where I live in (which are completely different from the USA's LTE bands).
After quite a bit of research, I found here and elsewhere methods to change LTE support for Qualcomm devices, but had no luck finding any for Exynos devices. Is there any way to do the same thing for devices with Exynos chipset, or am I stuck with no LTE? I also know it deppends on the hardware support for that, in my case I would need support for bands 3 (1800mhz), 7 (2600mhz) and 28 (700mhz). The phone covers none of those.
My device is not yet rooted, but I'm fine with doing so if needed.
Thanks in advance for any help.
I don't think you can physically change the bands unfortunately.
