[Q] Flashing roms

Hi,
I have SGH-M919V and its unlocked.
I am on Bell and want to use LTE. But this model has LTE disabled. when i enable it, cant make phone calls.
I cant seem to flash T mobile modem via odin. there is this secure boot issue. the AUTH: Fails.
I was thinking of installing Bell SGH-I337M rom on my phone. Is that possible? If so, how do I go about doing it?
Thanks!

Since you have a T-Mobile variant you should ask in the sgs4 tmobile forum...
However your problem with lte/phonecalls is likely just an APN issue
To further assist we would need to know which carrier you are using the device on

Hey. thank you for the reply, I really appreciate it.
I've been asking a lot there. No one is answering.
Please help me out, please.
My phone is Canadian variant, originally from WindMobile - SGH-m919V. Wind uses Tmobile freq. = 1700/2100 (AWS) only. No LTE.
I got it unlocked two days ago, and switched over to Bell carrier. Bell uses the other freq and LTE.
When I do force LTE by *#2263# - and enable all LTE, i get LTE speeds. But NO calling or texting. this is with the original Windmobile stock rom. No modification. No root.
I tried to flash Tmobile modem via odin 3.07, didnt work. I used the phone button to load the modem.bin. It gave me AUTH: Fail, secure check fail.

I agree, wrong forum, but we are here to please....
if you have a M919V then you would flash the rom you want, before you boot, flash a tmo m919V kernel, it will boot, manually add your apn settings for your device, it will work with data/wifi/calls.
Good luck....

Hi, im sorry for posting in this forum.
so if I want to flash the bell rom - I337M stock original rom , how do I flash it without booting??
And then how would I flash the tmobile kernel so then I can boot??
I dont mind keeping my current rom - wind stock. But, I want to be able to use LTE like how tmobile has pentaband 3g plus lte.

[Q] WIND Mobile Galaxy Note 3 SM-N900W8

First time forum user looking for some answers and a bit of help so thanks in advance for anything you can provide!
I just bought a Samsung Galaxy Note 3 from WIND Mobile in Canada. The model number was SM-N900W8. It seems although carriers know the device has the required bands, they limit listing them on their website if they do not support them and go one step further by having Samsung block the bands through some type of software cripple.
My concern is I use WIND Mobile when local and Telus Mobility when in fringe areas which WIND Mobile does not cover. Prior to buying this device from WIND outright, I confirmed with Samsung live chat support this specific model from WIND will support LTE on Telus. I was told I must first activate the device on WIND and they once I unlock the device, I can configure the Telus APN settings for use on the Telus network. When I do this, I get a max speed of 3G and in the network connections, it does not show: LTE/WCDMA/GSM (auto connect) but instead, the 3 original modes which you can select when on WIND Mobile: WCDMA/GSM (auto connect), WCDMA only and GSM only.
It seems as if the unlock and APN settings are the first 2 parts but in order for LTE to work, you must disable the cripple which Samsung has implemented for it's distribution to WIND Mobile since they do not support that frequency or radio band. My concern is it looks as if this must be done through a root or flash and I hear about phones getting bricked. I paid a lot of money for the device and cannot afford to damage it so do not know what options I have.
If I do enable LTE through a flash and then get an OTA Samsung update, will this remove the flash? How must I go about getting LTE enabled permanently without issue or is this not possible? Thank you for the help!

Hi fellow Windman

Thank you so much. I will follow this guide word for word but is there any risk of bricking my phone like I have read so much about? The last thing I want to do is mess something up and have a paperweight.
If I root the device as suggested and receive an OTA notification from Samsung to update the software, will this lock everything again and make me go through the procedure all over again or will it be permanently enabled? Thanks!

So, I rooted the device and assume it was successful since I have the SU (Super User) App installed. I ran the TWRP file which I assume is the OS which enables all the crippling Samsung initially implemented when releasing this phone to WIND Mobile but the problem still stands. I have entered all the correct APN settings for Telus yet it still only provides a 3G connection. Have I done something wrong and can any of you gurus familiar with rooting and updating a custom OS provide some insight. Thanks!

I think I'm worse than a noob. At least they can figure this stuff out! I followed the quick root steps and the twrp steps but was I supposed to do something else to enable LTE? The phone is definitely rooted and has the SU App installed. TWRP just seems like a program which allows installation of a custom ROM directly from the device but I may be wrong. My concern is the TWRP file I downloaded looks as if it's a tar file which the phone loads allowing HSPA and LTE capability. If so, it did not work on my WIND device.

You can't get the OTA if you have custom recovery installed. I.e. TWRP or CWM. You gotta wait for custom roms. I don't know about the lte thing

yea you're totally wrong here man... not sure how to enable lte capability, but wind's network is hspa+ already so that's enabled.
i do know you have to unlock it, likely with a sim unlock code or getting someone to unlock it, but after that, the theory is, that it should work.....

WIND is 4G and I have unlocked the device already. I am using a Telus SIM card and have correctly entered the Telus APN settings for LTE but it does not show LTE as a network mode which I can select. Seems to me Samsung has crippled this band since WIND does not support it. Since I have rooted the device, which I probably didn't need to do, I was hoping to find a flash which will permanently enable the LTE so it will function on Telus.

To use Telus LTE you need to switch to the Telus SIM card
then it should read the Telus APN from it, if not you can enter the Telus LTE APN and it should use it

I have done this already. The steps followed to date are as follows:
Purchased my WIND Mobile Galaxy Note 3 (model: SM-N900W8)
Unlocked the device through cellunlocker.net for 32.99 USD
Placed my Telus SIM into the device and it read the details. I was able to call and text without issue but did not have data connectivity. Contacted Telus and received the Telus LTE APN details and entered this information. Unfortunately, the network mode only shows 3 options: WCDMA/GSM (auto-connect), WCDMA only and GSM only.
There should be a fourth option for LTE capability but this is not displaying. I rooted my device and followed the TWRP step thinking this TWRP file was the rom to enable the LTE capability which seems to be locked but this is not the case. I am way off here but know it's probably something simple which I am missing!

yes, the 4th option for the LTE needs to flash another modem
i got it working here http://forum.xda-developers.com/showpost.php?p=46259468&postcount=39
find any of the Note 3 threads with flash-able modems, and flash the one from Puerto Rico that enables the LTE

To confirm your above statement, am I going to the following page and downloading the firmware for Puerto Rico?

or must I locate a thread to download just modem firmware and then follow the same ODIN instructions as I did with the other files?
Thanks!

you only need the modem, you don't need to flash an entire ROM.
there was a reference topic with a list of downloads for all different modems for the Note 3 in the General section of this Note 3 portion of the forum. http://forum.xda-developers.com/showthread.php?t=2475714
they are still uploading all the different models, you you might want to wait a bit, or you can extract it on your own, if you know how to do that from an odin .tar file.

Following the link you provided, it indicates the modem for model SM-N900W8 is "coming soon..." so it does not look like a modem is available for my model at this time. I tried looking for the Puerto Rico modem flash which you used but I do not see reference to it.
I was going to install the SM-N900W8 ROM for telus which would have the modem but as research indicates, if you install the wrong carrier ROM, you brick your device. I may have misinterpreted this but the last thing I wish to do is brick my device and have an expensive paper-weight in the end. Thanks again!

So I just got my phone unlocked with cellunlocker.net code, threw in a bell SIM and rebooted etc, it worked and was pretty quick but nothing too incredible. Was getting top download speeds of about 750kb/s (or 6mbps) whereas on wind I'd get about half that tops in my current location. My question here is, the phone said 3g....to me that seems way too fast for 3g but not nearly right for lte and I also couldn't see lte as an option for the bands. I assume that's cuz I still had the wind modem on the phone? Even when I went into the *#2263# screen to enable lte it still didn't work....
Any ideas? Should I flash the Puerto Rico Rom? Does it still work on wind bit just also let you use the lte radios when the correct SIM is in?

How long did it take to get your unlock code with cellunlocker.net? Which device did you pick in the dropdown?
I got a quote for 14.99 but guessing you have to pay more for a secondary search later?
UPDATE:
Never mind just got the code and it worked Cost me 14.99.

I'm really new to this but hopefully this will clarify some info regarding WIND and please correct me should I be wrong. There are two things when working with a phone. Customization to the OS and proper data connection. If you wish to tweak your device, push it to the limits and customize your OS settings, you can root your device.
If you wish to just enable LTE so you can use it on an LTE capable network like Telus, Bell or Rogers in Canada, you must flash the proper modem file to enable LTE. As I understand, the Puerto Rico Modem Flash will allow you to enable LTE data on the WIND Mobile variant of the Note 3. You can get the Puerto Rico Modem Flash from Post #27 by AllGamer at the following link:

Once confirmed, I'll update this post but if this works, I feel they should be thanked by clicking on the thank you button and a donation should be made for what you feel this information is worth and obviously, what you can afford.

Thank you for your reply. I am not sure why everything sounds so complicated.
I was able to flash a small file to my S4 (rogers) to enable the WIND bands. The phone did not need to be rooted, ODIN worked like a charm and my S4 became pentaband
This ordeal with the note 3 is not as straight forward. I have been following all your post but I see that you have not received any straight forward answers to your questions. I am not an expert when it comes to rooting or flashing so I would love a simple way of doing this.
Thank you again, lets hope that we will find an easy way to do this

Go to sammobile.com, search for your firmware, download and extract modem.bin from there. That's the file you need.

download and extract modem.bin from there. Then you can make this file flashable by Odin.

Not as easy as it looked. You have to get your phone to read the bands that T-Mobile is working with. There is a bunch of us, even a bounty out for it! Trying to get the N9005 version to read At&t LTE bands! Sure you can flash the modem but unsure if it'll work. Keep us updated though if you do flash and receive LTE service!

From what I can gather, due to others having same issues, it hasn't been possible (yet) one user notably @PatienceWithin had to sell his 9005 and get an 900A

just polling the community to see if anybody has figured it out yet or has gotten any closer... I'd really rather not resell my phone and buy a 900t but i really want lte... the baseband on these things are pure software, are the same baseband hardware as the tmo and att versions, there's no reason why it can't support the required bands. ugh!

4G on D802 HKG version

I have a D802 Hong Kong version. In the secret menu (3845#*802#) i have found this: LGD802AT-00-V10C-HKG-XX-NOV-30-2013
Now, I would like to use the 4g connection in my country (Italy, carrier TIM) but the 4g option is not avaible in "network mode". After a test with another G2 (italian version and same carrier), I can say that the connection don't switch automatically on 4g but keeps the H+ one. So i think is necessary a modification.
Solutions?
Is it necessary to flash an europe radio? or something else? I'd like to keep the stock rom Lg but is not a fundamental.
Baseband: M8974A - AAAANAZM - 1.0.190036
Kernel: 3.4.0
Build: JDQ39B
I have the g2 for two days. I know it very little. I do not have much knowledge about it. Some good soul can explain to me how to do?
I need your help!

Did you verify that the device has the correct radio bands for the lte on that carrier?

I don't know how to check! On the box of g2: gsm 850/900/1800/1900; wcdma 850/900/1900/2100; LTE 2100(B1)/1800(B3)/2600(B7)/900(B8)/800(B20).
My carrier is Tim but i don't kwow which band uses.
In secret menu/LTE Band section: avaible band 1,2,3,4,5,7,8,17,20,40. No one is selected.

Can i flash V10E firmware for Italy on V10C firmware for honk kong (actually on my device)?

Flashing different firmware wont help. Its either your apn is wrong or you didnt enable lte correctly. I checked and TIM uses 1800 (band 3) lte which your phone should work with.

Hi,
I've a similar question and I hope someone could help me: I've a G2 phone using the D80210e-ESA-XX firmware.
In the product specifications, supported LTE frequency bands are 900/1800/2100/2600/850. I know that in Italy working frequency bands are 800/1800/2600. Now, my phone does not support 800 MHz: do you think is possible to upload a different firmware (IT or EUR ones) on my phone? With one of these firmware, does the device will work at 800 MHz?
Thank you so much.

I also had the D802 with Korean firmware!
Even though the phone itself supports LTE the Korean firmware doesn't!
I flashed the EU version and everything worked fine afterwards!!!

[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)

Three things to note before proceeding...
1. I'm beginner im not responsible for any harm to your phone , I'm just sharing what i did to attain 4g services.
2. May be you already know all the things in the post but it can be useful for beginners like me .
3. 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

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!

This is good to hear and I second that!
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.

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).
