[Q] Bravo & Tmobile 3G USA - Bravo General

If I understand correctly - the Bravo has access to 850/1900MHz for UMTS but Tmobile uses 1700/2100MHz. Does that mean no 3g on T-Mobile for the Bravo?

If you use the defy baseband tool, the settings for T-Mobile are 850/1700/2100 so 3g shouldn't be an issue. I've always had success with the 1st choice (3.4.2-107-4) with at&t. Assuming you're American, one of the three us T-Mobile settings should work. If not you could try copying the baseband from the defy T-Mobile port. http://forum.xda-developers.com/showthread.php?t=1230251 The rom rip is advanced and not recommended if you don't know how to fix a "mess up". I'll post a tutorial if defy baseband doesn't work for you.

It does not work with T-Mobile's 3G, Bravo frequencies are 850/1900 mhz while T-mobile uses 900/1700/2100 mhz.
Bravo hardware allows only these frequencies.
Baseband switcher cant manage that!

Didn't know that. Never looked up the frequencies. I've only had 2 connection problems, and baseband fixed it. Except for the latest two cm9 nightlies. Haven't tried to fix since it's on multiboot and cm7.2 works great. Saw the thread in Dev and will post back here if I find something since I haven't reached 10 posts yet.

I am in the USA using the T-Mobile network.
I tried the defy basebands on my quarx/cm7 bravo. Out of all of the basebands I tried the radio would not establish a connection. No 1G, 2G nor 3G connections were possible with these defy T-Mobile basebands.
Luckily I backed up the /system/etc/motorola directory and restored over the changes that the defy baseband changer loaded. I have 2G back in action after the restore.

The best sbf for the US?

I cant seem to find a working sbf for the US. When I flash the UK I get a black screen, when I flash personal Argentina I get everything but I have no service. Can someone help me please? My network is the same as att. the Argentina says that the network is not supported.
Well, you may be out of luck as of now. If your baseband is not same as Personal Argentina (or similar LatAm ROMs) for which there is no root, you can't use baseband switcher and may just have to wait until those ROMs get a root option.
So there is no way back to my original sbf?

No, at least not yet... You can't root nor apply other sbf, you're stuck with it until someone finds a way to change it.
Is it not possible to root through sbf files? I cant believe I spent all this money and now I have a paper weight.

It's not possible... You can look at the discussion about Vivo BR and Personal AR In This Thread, although there's no solution yet.
OK, so will having another country's sbf make you now be able to use the phone? I get "Mobile Network not available".

What's your carrier?
Brazil uses 850/900/1800 bands for GSM and 850/2100 bands for 3G.
Argentina uses the 850/1900, the same band AT&T uses.
I've been in the US and used my milestone 2 in AT&T network without any problem. It won't work in T Mobile, since it uses 1700/2100.
Try with an AT&T (or one MVNO which uses their network, like H2O Wireless) sim card to see if works.
Maybe you could try using Vivo BR sbf. Our phones in Brazil are all carrier unlocked nowadays.
HTH
I'm using Straight Talk which is on the ATT network. I have not been able to get the phone working no matter what I try. I have checked the settings over and over.

[Q]Restore Missing Service Menu in Atrix 4G ( GB)

I have a Atrix 4G international version but not connect to 3G HDSPA in 900 Mhz. I tried flash different radios with CWM Touch (N_01.77.30P_usa_att_25jun2011.zip, N_01.100.00R_de_o2_22sep2011.zip, N_01.100.00R_europe_retail_09oct2011.zip, and others) to change the baseband, but unsucessfully and now, the hidden service menu access through *#*#4386#*#* is missing.
Here exist any way to restore the service menu and stay trying change the base band?
What baseband or radio sbf is recommended to work HDSPA in 900 Mhz?? other post in XDA don't clarify this question.
The phone is unlocked with Max Blur 5 Rom, and actually baseband is N_01.100.00R_europe_retail_09oct2011
Auto-help: I find a program called "Hidden Menu" in Google Play. This app open the service menu and many others dialer tricks.

How to add extra baseband to CM7?

My carrier uses 900/1800 baseband. I tickled through all regions and carriers and didn't find 900/1800. The closest option is 900/2100. How to add 900/1800 baseband to baseband selector?

Did your Bravo come with the 900/1800 baseband? If so, you lost it when you flashed CM7. There is still hope, find someone with a stock rooted Bravo, or a Defy/phone with same radio, that uses your carrier and upload the entire system/etc/motorola and I'll be able to help you out.
I know that the Defy, Defy+, Bravo, & Milestone 2 all have the same radio. Start with those phones then expand to other Motorola Omap 3630 phones.
If you made a nandroid of your stock with that baseband and it worked just fine, restore it and upload that directory.

Frankly, I don't remember which baseband I used with a stock Bravo. I started to worry about that after I had flashed CM7. Before CM7 I had got CM10 and the signal strength was pretty good in the Underground, but when I had flashed CM7 my phone wasn't able to connect to network. So I started to think that there was something wrong with CM7. When I checked baseband I saw that my carrier baseband GSM900/1800 is not in list (btw, CM7 900/2100, is the first number for 2g and is the second for 3g? or are them both for 2g?). And I thought that signal might be lost because of difference in baseband. But than I flashed WR yesterday. I have a strong signal in the Underground now (in baseband selector I checked 900/2100). So the signal strength is not depend on baseband but on ROM.

The baseband shouldn't be dependent on the rom. If you have a working signal in CM7, then the same baseband should give you a working signal in CM9\10\MIUI. I actually use 3 different basebands that I use -- they all work good for me, but in low\no signal areas sometimes changing basebands will increase or give me a signal. It'll be boring, but go to Settings>Advanced>Baseband Selection and try out all of the 900mhz basebands until you find some that work well for you. I use 850mhz basebands so mine won't help, and to all the other 850's -- there's only 3, 4 including ATT stock which isn't in Baseband Selector. And for the other question, both are for 2g, 3g, 4g -- what's being transmitted over what particular frequency all depends on the governments and local standards (and your hardware )

Thanks. Will try different 900mhz someday There may be some tweaks in ROM. For example, for battery saving or signal power increasing, I guess Anyway, It's OK in WhiteRabbit rom now :good:
I was so happy with WhiteRabbit because of strong network signal. A couple weeks later my phone has got weak signal again... I have no idea what has happened. It doesn't depend on rom as skeevy420 said. But I do believe that it's software problem. May it be some power-save profile?
Have just posted a request to add my baseband at Defy forum. Maybe it could help..

[4g fix] on Fulmics Rom for verizon VS985

Four things to note before proceeding...
1. This only works for users having vs985 model outside the US or not on verizon network.
2. I'm beginner im not responsible for any harm to your phone , I'm just sharing what i did to attain 4g services.
3. May be you already know all the things in the post but it can be useful for beginners like me .
4. Sorry for the english as its not my native language.
So Hi guys i installed this rom and as usually i was not getting any 4G or lte network.
Then i go to my network provider's website to check on which Band or frequency 4g services are active. ( for this i just googled 'idea 4g band' and i am redirected to my network provider's website. Here 'idea' is the name of network provider.)
So i found that in my region 4g services are active on Band3
Different careers use different Bands to provide 4g services such as band40 , band17 etc
Then i go to phone's hidden menu by the Advanced Menu of Fulmics Tweaks.
In hidden menu i select Modem Protocol > LTE Band Selection
There i select Band3 but i got "Fail' message on screen , however when i select band4 it gave me a 'success' message.
It means on my phone band4 is active but not band3.
All this information of Bands are stored in Modem or Bootstack section of our phone.
May be fulmics rom is having a band concerned with international rom So now i need a modem on which Band3 can be activated by going to hidden menu.
So i just flashed 35b Bootstack compiled by @xdabbeb.
Which can be found in this thread http://forum.xda-developers.com/verizon-lg-g3/development/xdabbeb-s-vs980-2-0-0-t3231279
After flashing when i tried to select band3 in hidden menu it gave a 'success' message . It means Band3 is activated on my phone. And now when i searched for all networks in Networks Menu of Phone Setting. I got my network listed and i successfully registered on it. And got 4G NETWORK.
So first of all you should know on which band your network is working and then try flashing different bootstacks on which your 4g Band can be activated.
Flashing wrong Bootstack can brick your phone
""Do not flash any bootstack above 35b. Custom roms are still not compatible with bootstacks above 35b""
You can try 24b , 12b. (But im sure only about 35b as i tried only this)
Again I'm not responsible for any harm to your phone. Use your mind and search thoroughly before taking any step.

Hi there, thanks for the info. What area are you in and where did you find what band you needed? I have tried numerous times with all the bootstacks and never had consistent 4G.
@mopartonyg
I'm in India and i just checked my career's website to know which band they are using. However in USA Verizon wireless uses Band12 as Primary Band and Band2 , Band4 as Secondary band to strengthen the signal in densely populated urban area. So if you are verizon user in USA band 12,4,2 must be activated. I can't say anything about consistency as it varies from place to place.
Actually Verizon uses band 13 for it's primary along with bands 4 and 2. Not having any luck getting data to work on Fulmics with this method. I select band 13 and band 4 (as band 2 is not in my area) yet even with that I still can't get data at all on Verizon with Fulmics.
same boat here... actually the only band I can get working is 4. I have to assume the design of the international rom with the band they are designed around, just don't play nice with our CDMA harware/modem partition. I would suspect that the international roms would require some engineering for them to really work properly. not sure if just porting them over and chaning settings is going to get the job done. perhaps someone more intelligent than I could share some light, but there certainly is a conflict with how these roms communicates across the CDMA bands in the US

One thing i noticed here... that only Verizon sim users are facing problem regarding 4G whereas other international users like me ( and some of my friends in China are free to select any network ). So may be verizon is creating restrictions as when i was on Stock vs985 verizon Rom ( unrooted) , i was not getting any official ota updates. It always says your software is up to date. But then i found a statement in Verizon's website that you will not get any official updates if you are not having verizon sim.
So verizon knows what Rom and what sim we are using.

A couple of good approaches to the issue. Although it needs to be noted 4G is directly related to the band on each carrier (VZW, TMO, etc) See Below
Carrier 4G LTE Bands Frequencies
Verizon Wireless 2, 4, 13 1900, 1700 f, 700 c
T-Mobile 2, 4, 12 1900, 1700 def, 700 a
Sprint 25, 26, 41 1900 g, 850, 2500
Europe 3, 7, 20 1800, 2600, 800
If a specific ROM cannot be set to the correct bands above, it would make sense to me that Verizon wouldn't work in Europe on a stock VZW ROM. It would not be able to use the channels in Europe.
And vice versa, that Verizon wouldn't work in the states on an international ROM in the US. Whether the Verizon SIM is blocking that band, or the design of the ROM, would be a better question for the developers.

Warid's approved devices will definitely work with Warid's LTE network. For our "Warid LTE Approved' devices please visit the "Warid's LTE devices" section. You can also purchase LTE devices that support 1800 MHz (FDD-LTE Bands 3) from other sources. However, Warid doesn't take responsibility for these devices if they do not work on Warid's LTE network http://www.waridtel.com/lte/faqs
So it makes sense that if BAND 3 works international (see above) that you get 4G
The one thing I noticed after activating bands 13 and 4 (with the proper VS985 35B bootstack) in the hidden settings is when I searched for my network under network settings it does bring up Verizon but it fails authentication. So it's like there is something missing in Fulmics ROM itself that would get it to where the ROM will work with Verizon's network. So is it a matter of lifting whatever files from say 47A/47B into Fulmics that have the Verizon VS985 specific info to get it to work perhaps?

I think now its not a matter of bootstack. Because even when Required Band is activated we can't register to the Verizon. Xpirt mentioned in a post that he is working to resolve network issues in Verizon models. We can hope that this problem will be solved in next version However xdabbeb shared that the 47A modem won't work without the corresponding 47A secondary bootloader (sbl1). Unfortunately, the 47A sbl1 doesn't play nice with the last bump-exploitable Android bootloader (aboot) we have from 12b. If you use that pairing, you'll put your device into 9008 bulk mode(Hard brick).

The good news is we do have 47A ROMs that are using the 35B modem so there is potential that Xpirt could use that as a source for a fix with the authentication issue. So @xpirt if you need anyone to beta test fixes my VS985 is ready to help!

Looking forward to getting it fixed and use it as my daily driver. It would totally be worth a big donation, thanks to everyone working on making this available to so many.
Great discussion towards the development of the International ROM's for our VS985. I was able to get 4G with Andy's 30A ported ROM...although the signal bars never came up on my phone, I was able to get the 4G speeds. I noticed that the APN XML was filled with Chinese... So for whatever reason and way, my phone was able to grab "somebody's" 4G tower. I'm hoping the RIL (Radio Interface Layer) and libraries were pulled over and perhaps this could provide some more insight to @Xspirit

I am on BlackSoulxxx latest LG G3 Tekcafe v5.3 D85530A-Full G5 ROM. Here's what I did to get the bars with 4g data. I tested it out in areas where there is no cell service and in areas where there is 1x or 3g and the 4g came back. I even made a backup of the ROM wiped and installed another marshmallow aosp rom and others. I then went to restore BlackSoulxxx ROM and 4g signal still came back.
Steps I did.
1. Tot'd back to stock 10b and rooted and installed twrp.
2. Flashed LG_G3_Flash2BackupEFS.zip of the 10b rom.
3. Wiped stock 10b and flashed the 10b G3_EFS_Flashable_Restore.zip that was created from the the LG_G3_Flash2BackupEFS.zip.
4. Flashed BlackSoulxxx rom and after it booted up I had signals but not data until I entered the Verizon APN manually see picture of what to enter. If mobile network is greyed out flash 35b bootstack.
5. I entered the verizon APN and selected CDMA then global I got the 4g icon with signal bars I changed the icon with a buildprop edit.
I just don't get signals while in 1x or 3g but data does work still and it will get 4g again if your in a 4g area. The phone does say T-CDMA 64. Here's a https://drive.google.com/file/d/0B-EyVOQK1xDAa0VmbERXcUlrV1U/view?usp=sharing to change it to Verizon Wireless courtesy of @xpirt.

I am on BlackSoulxxx latest LG G3 Tekcafe v5.3 D85530A-Full G5 ROM. Here's what I did to get the bars with 4g data. I tested it out in areas where there is no cell service and in areas where there is 1x or 3g and the 4g came back. I even made a backup of the ROM wiped and installed another marshmallow aosp rom and others. I then went to restore BlackSoulxxx ROM and 4g signal still came back.
Steps I did.
1. Tot'd back to stock 12b and rooted and installed twrp.
2. Flashed LG_G3_Flash2BackupEFS.zip of the 12b rom.
3. Wiped stock 12b and flashed the 12b G3_EFS_Flashable_Restore.zip that was created from the the LG_G3_Flash2BackupEFS.zip.

Great job posting your step by step instructions. I've been able to achieve all of the same on a host of international ROMS however with a couple of caveots. I can either have SMS/MMS working properly, or break SMS/MMS and have internet with signal bars. Question about the file above. This will just modify the header, or will it specifically put you on the Verizon network?

It'll change just the ROM from saying T-CDMA 64 to Verizon Wireless for Verizon users (VS985).

So when you go into the About Phone>Network, does it say Verizon Wireless for the network?
