Hello,
I've seen the thread that focusses on adding AWS to AT&T versions or re-adding AWS to Rogers versions, but has anyone tried enabling AWS on an RM-821? Could it work by flashing the Euro developer's ROM?
Thanks in advance!

The ROM does not control what bands the phone can receive. The bands are hardware and no ROM on earth will enable or disable them.

It is impossible to enable radios on a phone when they don't exist. Only the RM-820 variant has the AWS radios in the wireless modem. This is why you are able to possibly enable the respected radios with the AT&T model after flashing, due to them disabling the AWS radios for WCDMA/UMTS. On the European/international units, they use an entirely different LTE module to work with LTE networks outside the Americas (Russia for example uses the 2600MHz band for LTE, a frequency not present on the Americas' version). This incompatibility issue though, is good for power users, and LTE users everywhere. If your device was broadcasting all these different frequencies at once, the modem would simply drain your battery extremely fast. In the future, Qualcomm will release chipsets that will have all the frequencies needed on a single modem. The firmware would then optimize the LTE bands you need to use that operator's LTE network. Keep your hopes up and hope they release this within the next two years!

Hello everyone ... I bought a Moto E XT1524 in Spain. The phone works on 3G bands 900 and 2100. In Argentina, the country where I live now, the 3G bands are 850/1900. Because of this my phone only works in 2G. Looking I found this post http://forum.xda-developers.com/moto-g/general/unlock-hspa-bands-moto-g-1700mhz-xt1032-t2878441 that explaining how to unlock bands. The question is whether you know if the phone will have this possibility. I mean, if the chipset supports these bands and doing the procedure will fix my problem. Or definitely is a limitation of hardware.
Thanks!!!
I assume that the hardware is the same between phones, and that the radio bands are set by firmware. If I'm right about this, you would need to flash firmware on your phone that supported the bands that you want. However I am only guessing about this.

Good luck and expect a modem brick.
Hi all,
I got my sprint Moto E a few weeks ago. Its working international, but the problem is that its locked to 2G only.
I think its the radio that is locked.
I had a smilar issue with my HTC one E8 sprint when it was updated to Lollipop where the #G part of the radio was disabled. I used this method here to unlock the UMTS900/UMTS2100 portion.
to do this with the Moto E, I need the SPC code to program the baseband. I have had little success with the SPC. If anyone can assist, maybe we can make it a global phone

If the spc code was obtained, would following those steps allow it to be used with any carrier?
The spc code is unique to each phone. If I can get spc code for the device I currently have, a solution is possible

Here is how i got my msl: i called my provider and asked them, when they asked why, i told them it was for development purposes.
Unfortunately, I am outside the US, so I cannot call sprint

did you have to do anything to get it sim unlocked internationally or did it work out of box?

can you let know if you had to do something special to get it unlocked for gsm use internationally or is it unlocked out of the box.
Also would you recommend this phone or lumia 640?

Based on my experience with this phone, (Moto E 2015 Surnia xt1526,) I think that the lock on this thing is in the modem. Im not 100 percent sure though.

I haven't been around here long enough to have come across it - do you know if the modem files are typically flashed with ROMs on this device? If so, can we swap out modems between custom builds with little or no issues? I don't recall seeing a modems thread, so I'm assuming they aren't typically flashed separately.
I still don't plan to get a CDMA sim card, but I do have sim adapters coming, so I can see what I can get working with my AT&T sim.
Maybe I will be chasing LTE issues after all - really having fun messing with this device.

I know that it does use modems, as far as I'm aware, it has 2 parts, fsg and the Helios h.bin thing. As for switching them out in a custom build, I'm probably going to test it.

OK, those are both new to me (this is my first Moto smart phone) but gives me a place to start looking. Sounds like from what you said that all these ROMs include modems (some devices I've been on ROMs typically did not, modems were flashed separately as needed).
Sent from my SAMSUNG-SM-G920A using Tapatalk
Custom ROMs do not come with their own modem's, they utilize the modem that was present in stock before you flashed. The carrier lock is definitely in the modem though

OK thanks, that's the info I was looking for. Still haven't had time to dig into older info/posts - are you aware of any discussion regarding modem changes? Are we capable of flashing modems separately? Has anyone compiled a list of modem firmwares?

If I might add, i am wondering if we could flash a modem from the us retail version or other and maybe remove the lock? I don't know if it would work, but there is always a small chance it might. Another option might be to have someone on a gsm variant to pull the modem files and maybe we could flash that in fastboot? I don't know for certain, but i think it might work. If it doesn't, then the lock must be elsewhere.

Do the GSM variants have hardware support for the same radio bands as the CDMA models? If not, I'd guess flashing GSM radio on CDMA device won't be a good idea

So now that all variants besides the T-Mobile V30 have root I am hoping maybe that opened up more options to get more USA bands working on my India H930DS.
I read a few threads about adding bands on older phones with root access particularly this one for the Galaxy s5:
https://www.google.com/amp/s/forum....o-add-rf-lte-frequency-bands-to-t2886059/amp/
It details the whole process of adding extra 3g and LTE bands on a rooted s5 with custom rom/kernel. He also states it should work on any Qualcomm based devices.
My question is will something like this work on newer devices such as my H930DS V30+?
Also i am not sure but i am assuming the "ids" he mentions in the steps 17-23 are going to be different?
Can any experts here confirm weather the process in the thread i linked would be relevant for my purposes or any other methods that can take advantage of root to add/enable more bands?
Ah come on. Someone at least give me some hope that i can keep this phone.
Back in 2015 we tried that Qualcomm method with Moto Quarks (Moto Maxx, Moto Turbo) and it didn't work. I don't know about LG phones.
I think no only one is answering because they really don't know.
All I know is when you flash Sprint LS998 to US998, it takes on those bands and loses a couple of Sprint bands. Sprint guy @JWnSC reflashed Sprint modem and got them back. So it IS possible to add/remove LTE bands from the V30. Whether it's possible in the way you need, I don't know. You're crossing hemispheres.
Alright thanks for the answer. I just don't want to go through the whole process of bl unlock and root just to find out I can't even get the tools to connect to the phone and read/write the bands or something stupid like that.

I can add, when I flashed the VS996 modem back after BL unlock/root, the hidden menu did not show the additional bands that, according to GSMArena, should have been present (46 & 66). Instead, it showed the native US998 bands and my connection was screwed up.
It may have been something I did or didn't do... I don't know.

Maybe some description of how to flash the modem correctly is what we need. I just flashed the modem partition using patched LGUP with the VS996 kdz.

Here's what I don't understand. If you flashed the H930 over your H930DS phone, these are the bands you should have...
If you have"H930" (either actual or converted), you will have these bands:
2G GSM: 900 / 1800 / 1900
3G (HSPA): 850 / 900 / 1900 / 2100
4G LTE: 1/2/3/4/5/8/12/17/20/28/38

So what bands are you missing that you need to add? I know Sprint users want LTE band 26 and 41, which can be added back by flashing the Sprint modem. I know T-mobile users would love LTE band 71 (probably not going to happen). Verizon users want Wi-Fi calling back and that's been solved.
But you SHOULD already be getting LTE on AT&T or T-mobile on the existing bands.

That is the problem I'm encountering. I flashed the H930 kdz on my H930DS and I am still not getting the H930's bands, only the H930DS'. I'm not sure if I did something wrong here. I also tried to use partition dl mode in LGUP to flash only modem, xbl and xbl2 from the H930 kdz but still no change. Any help?
I don't know, maybe 66? I think 66 is extension of band 4 right? Something I read somewhere. All I know is nothing I tried would let me get anything better than a 2g/edge connection at home and a 3g connection in town. It was constantly only being able to get 2g that bothered me. If I could have gotten a consistent 3g/hspa connection I would have been more than happy with it. Anyways I just gave up and sold it.
Which bands are you missing?
The bands listed for the H930 earlier is not correct either. It supports a few more than that.
---------- Post added at 08:56 PM ---------- Previous post was at 08:52 PM ----------
According to GSMArena, India uses these bands: LTE 850 (5), LTE 1800 (3), LTE 2100 (1), LTE 2300 (40), LTE 2500 (41). All of them except 41 is supported by the H930DS. It sounds more like your APN settings were wonky.
All I know is with the same SIM card I am getting LTE+ connection on my new essential PH1 in the same spot I was only able to get 2g connection with the h930ds.
So has anyone figured out a way to add LTE bands to their US998?
I am stuck with AT&T H931 firmware mainly because I don't want to lose band 30. The more I dig into the AT&T firmware, the more I dislike what the big brother did.

Because your H930DS is not made for North American carriers. It's missing most North American carrier LTE bands. So, all you could receive is 2G bands.
Has nothing to do with SIM card, has everything to do with you not researching what you bought. .
You should have bought Open Market US998 V30+.

You can root and debloat the AT&T firmware if you wish.
I have a ANE-LX3C25 it had band 5 enabled but i changed it to LX1C432 and it can not longer get LTE, it seems that there is no one in this forum with c25.
Can someone tell me if C432 supports band 5? If so what did go wrong?
If it doesn't can someone share Oem info of a model with band 5 enabled?

Where are you located? I'm in the same shoes, I reflashed an LX1C432 (European) into LX3C605, hoping to have LTE but all I get is Edge on US T-Mobile.
