I just recently bought a Moto E 2015 for Virgin Mobile from Wal-Mart, and after messing around with various ROMs for a while, I decided to go back to stock.
After managing to get my phone reflashed with both stock 5.1 and stock 5.0.2, but on both of them the mobile network can't or won't turn on.
To turn on or off or change the GSM band tries to use RadioComm 11.12.2.

RadioComm appears to only be for up to 3G phones, and is otherwise extremely complicated. Can you explain how to turn the GSM band back on?
GSM bands wouldn't be causing these issues, as Virgin/Sprint uses CDMA for 2G/3G.
Double check and make sure that the stock you're flashing is for the XT1526, and not for other variants. If you're keeping a custom recovery, try flashing the Sprint modems after you flash stock.

4g wont work on l9, on this phone you can use 3g(internet) segnal or 2g(sms and calls)
to use 4g you must have a phone that support this tecnology(HARDWARE)

Please make sure that after unlock boot loader you flash your original kdz back by offline method. I think it a incorrect baseband problem.

Yea my t-mobile L9 (P769) uses 4g as well, however I do not believe they are LTE capable (correct me if im wrong). Many people think 4g and lte are the same.However they are not.
my phone is lte capable. 4g LTE

That is not true. Not a single LG optimus L9 variant regardless of model or network supports LTE. However they are capable of running 4g just not 4g LTE. The 4g runs off HSPA+ not LTE. Even the LG optimus L9 II uses HSPA+ for the 4g network.
T-Mobile USA seems to define 4g their way. Something like gsm, umts, hspa & cdma, that makes four.

Thats all the radio bands the device can pick up. 4g acctually runs off the hspa. If you change your prefered network to gsm/cdma or umts only or auto it will not connect to 4 g. In order to connect to 4 g you must select hspa+ auto or wcdma+ auto. I couldnt connect to 4g when i first got my phone and its because the prefered network was set to gsm/cdma (auto). I get the best speed on wcdma+(auto). That will make it connect to the fastest radio band available. My phones a t-mobile but I unlocked it and switched to at&t because tmobiles data speed was horrible. I would average .20 mbps - 2.25 mbps (bits not bytes) with tmobiles 4g. On at&t I get 12mbps to 25 mbps and have even got as high as 40mbps right in town. Thats just in my area however, im sure tmobile has good speed in certain areas. After switching to at&t it made me miss my lg p870 I gave my girl because its LTE and she gets anywhere from 20-50mbps!?
I'm using the Verizon Wireless LG G3 on Cricket Wireless which is a GSM carrier that uses AT&T towers.
I've been using Android 4.4 with the 10b modem and my 4G LTE has been working great since I got this phone about 6 months ago. I have TWRP on my phone, so I went ahead and upgraded to Android 5.0 (with 23b modem) and no longer have any LTE at all. I can only connect to HSPA+. I did a nandroid back to 4.4 where I left off and I have my LTE back.
I know many of you are probably using your VZW LG G3 on Verizon, so i'm reaching out to anybody else who may be using it on a GSM carrier. Can anybody help me with this? I'd love to have Android 5.0 on my phone, but i'm not willing to lose LTE, so I'm back on my nandroid of 4.4 until I can figure this out. Any help is greatly appreciated...
Someone asked in the other thread you asked this if you kept your APN settings from your KitKat ROM, since they would be necessary to have the full network features on any other ROM / update.

Im jealous u have lte im on cricket and my phone was already 12b whn i got it also can you post your apn settings
My APN'S aren't the reason I get LTE. I get LTE because I'm on 10b radio. When I try to use the stock lollipop rom it upgrades my radio to 23b and disables LTE. I installed CM 5.0.1. nightly with 10b radio and I get LTE on Android 5.0 now, but only on CM or AOSP. I've tested all of the modems with my phone and I get LTE on Cricket Wireless with 10b and 11c modems, but absolutely no LTE with 12b or 23b. It's the radio causing the lack of LTE on GSM carriers. I think it's Verizon's way of still trying to carrier lock their phones a bit. I never had Verizon, I bought my G3 on craigslist for $100...
And it was me who asked that in another thread, my bad. Was just trying to get to the root of the problem and I did. I would still love to use the Stock Verizon based lollipop ROM with my phone, but it installs 23b radio which disables LTE. If I install the 10b radio while that ROM is installed, my signal will cut out every 15 seconds or so...
So i'm hoping someone can tell me how to install the stock lollipop ROM with a different radio, that would be fantastic!
Dang that sucks. I couldnt take it anymore installed the ota lsdt night and switched to Verizon prepaid

Well I did figure out if I use 10b or 11c modem that I get LTE on cricket or GSM networks. If i use AOSP or CM 5.0 based ROM I get LTE also without signal cutout. Just can't use the stock Verizon/LG based Android 5.0 ROM
I like cricket because they offer me 20GB of mobile data per month and unlimited talk and text for $60/month

That is a great deal for cricket. I checked my Phone LG G3 VS985 with cricket website and it says it only compatible up to 3G data speed??!!
I currently have T-Mobile with only 4GB and $55 per month.
I run my vs985 on stock rooted KitKat - not sure which radio I installed last - on both Cricket and T-Mobile pre-paid sims, sometimes, and I get great LTE on both, when available in the area. So, the Cricket website is just wrong about H+ only.
Also, AT&T wholly owns Cricket, which contains AIO now.

I am on T-mobile, and I want to share my LTE experience. The phone comes in 12b (Kitkat), and I can get LTE on band 4. I then downgraded to 10b (both ROM and radio), and I still get LTE, so both 10b and 12b radio should support LTE band 4. I haven't tried 23b yet as it is Lollipop 5.0.1 and it has memory leak issue that is to be fixed on 5.1.1 or later. I had 5.1 on my old Nexus 5, and the memory leak issue is very annoying. The apps will randomly hang and not responsive.

So, 12b radio does allow LTE on band4 like on T-Mobile ? Others say not on Cricket band4. I wonder which is correct if not both ?
Anyone can tell me how to check which radio version I have installed ? I thought it was 12b, but don't know how to see. I think it was to enable VoLTE, but I have never set that up on my account due to reports of transition difficulties.

Cricket is AT&T MVNO, and AT&T main LTE band is 17, which is not supported by VS985. Band 4 is a supplemental LTE band for AT&T, so it may not be available in many area. LTE band 4 is definitely supported by 12b modem.
My 10b modem Baseband version (last 5 letters) is NPZM-1. Maybe someone can report their 12b modem Baseband version here.
I get excellent high speed LTE on both T-Mobile and Cricket (cheap but throttled AT&T) everywhere I have tested here in NC and Virginia and Seattle. So band4 is not too rare on AT&T.
My modem ends with NPZM-1.7834.1 so it might be the same as yours ?
I think its pretty interesting that all the band 2 LTE is rolling out will work on practically no current phones except the N6 and some couple of Samsung variants. Hope the G4 will support it.
One of the reasons I hesitate to update to L is that I don't think anyone has found a way to enable the G3's band3 LTE yet on Lollipop and I want that for Europe travel.

I think your modem is probably 12b. My 10b modem ends with 1 without the ".7834.1", so yours is newer than 10b. Good that the band 4 works out for you on AT&T. I am on T-mobile, and my LTE speed is great too in the San Francisco Bay Area. I usually get between 20-30Mbps, but sometimes can go up to 57Mbps.
Nexus 5 supports band 2 too. About band 3, maybe you can try enabling it on 12b and then upgrade to L to see if it stays? I enabled band 3 on US version of Nexus 5 and it stays when I put new rom on it. Not sure if it is the same as Nexus 5.

I have Cricket Wireless which is owned and operated by AT&T so I use AT&T towers.
You will get LTE on your VS985 using AT&T only if you're on 10b or 11c modems. If you use any modem after 11c it disables LTE. I have no clue why. I installed Illusion ROM on my phone with 10b modem and I was still connected to LTE. The only ROM I have encountered that I do not get LTE on are Stock based Lollipop ROMs because of the 23b radio. When I was on a stock based Kitkat ROM I was able to connect to LTE as well because of the 10b modem.
Stick with 10b or 11c Modem, and you will have no problems connecting to LTE.
There are also ways to enable other LTE bands on your phone. I use shortcut master Lite to enable those and change the way my phone connects.

No. Other than the international band3 LTE there are no other bands you can unlock. Just band 4 for at&t and T-Mobile LTE, already unlocked.

Hi!
I have the Verizon Moto E 2015 XT1528 here in the Philippines.
I had the GSM working by changing Network Type to "LTE/GSM Auto".
Unfortunately LTE wasn't working because LTE bands in the Philippines are not activated in the XT1528.
While I was looking for how to activate the bands, I stupidly set the radio to USA Band. After that I lost the GSM signal even if network type is LTE/GSM.
From reading in various forums, it seems that I would have to flash the unit to the original firmware.
However, I cannot find a copy of the stock firmware of the XT1528 and at the same time I also read that the XT1528 cannot have the bootloader unlocked.
Can anybody help me as to how to proceed to restore the GSM signal?
Thanks.
hey bro, this is somewhat off topic, but My sister is going to the philippines and she bought this phone to use it there, Does it get any phone signal at all? no need for Data. she just needs to use it for calls/texts. I have unlocked it already via the instruction on the general thread.
Yes. It will get a GSM signal. Also can get EDGE data. No 3G or LTE though
I've used the Network app (looks like a phone) to switch bands back and forth. Give it a try.
is there any options to unlock lte band 3 on ls990. i saw and tried many other roms but no one has this feature.
is that depends on rom? or kernel or modem?
Tried woth shortcut master but doesnot work

are you sure that is gets only edge? Sprint rom only have GSM icon regardless what it receives (edge,3g or hsdpa).
and you may also check if 3g frequencies match

Here is some information about the ls990 data network
TECHNOLOGIES USED
GSM / CDMA / HSPA / EVDO / LTE
TECHNOLOGIES USED DEFINED
GSM
Global system for mobile (GSM) communication is a digital mobile telephony system that is widely used in Europe and other parts of the world. GSMuses a variation of time division multiple access (TDMA)
CDMA
Code division multiple access (CDMA) is a channel access used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single access channel.
HSPA
High speed packet access (HSPA) is a third generation (3G) mobile broadband communications technology. The term "HSPA" actually refers to two specific protocols used in tandem, high speed downlink packet access (HSDPA) and high speed uplink packet access (HSUPA).
EVDO
1xEV-DO is a 3G standard for CDMA-based networks, as a 3G technology it focuses on bringing high-speed data to CDMA. EVDO provides data rates over ten times faster than 1xRTT the previous data technology for CDMA networks.
LTE
Long term evolution (LTE) is a 4G wireless broadband technology developed by the third generation partnership project (3gpp) an industry trade group.
Bands used by the ls990
2G Bands
GSM 850 / 900 / 1800 / 1900
3G Bands
HSDPA 850 / 1900 / 2100
4G Bands
LTE Bands 25 (1900) / 26 (850) / 41 (2500)
DATA TRANSMISSION SPEED
HSPA, LTE Cat4
150 / 50 Mbps
I don't know what protocol Band-3 is set up for. So I cannot answer your question directly. What I can tell you is that the coding you are looking for should be part of your CDMA. The CDMA gets the two signals (your phone and the band) to share a frequency. I don't know how this is achieved. If you know how to access the CDMA programming and know the precise frequency your desired band is broadcasting at you very well, at the very least change an existing port to a different frequency.
I don't know if you would be able to just add in coding and expect it to work. That's because I don't actually know if the phones use multiple ports (one for each frequency) or if it cycles through the programmed frequency using one piece of hardware.
I hope at least some of this information is able to help you out. If you do end up attempting to rewrite a CDMA, let me know how it goes. Honestly if it works, I'm going to be asking you for information.

I'm just a regular guy but try looking through all of the forums and threads. Just search CDMA (make sure you select find anywhere in text if you use a web browser. Then you can use your browser's tools to "find in page" again search CDMA. This will highlight every time "CDMA" appears on the page. Then you can scroll through them by pressing on the arrows on the find in page tool. Of you can't find anything in any of the posts on this site, there could be the chance that the developers are not interested in altering their CDMAs. Keep in mind it is common advice to never alter your "daily driver" the cell you rely on.
Other than that the only I formation I know about it is what I was told by a guy who flashes phones for a prepaid provider where I live. He told me that not every phone is able to hook up to the bands of the other carriers. That's why he had a sign that stated data service is not guaranteed on all phones.
