There seems to be a problem that is common to all marshmallow ROMs, on N900T and possibly also
other versions: once GPS locks, it immediately unlocks again, to lock again, unlock again, and so on.
(I find it easiest to see with the app GPS test - but flashing can be seen on other programs, too)
I've seen it described on Phronesis 6.0.1 (see, for example post 4869), Darklord N7 port (in this thread they seem to be using the app GPS location tracker, which seems to solve the problem, but use battery).
So, my questions are:
Does anyone have GPS working correctly on marshmallow with N900T?
Does this problem occur with any other Note 3 version?
What are possible causes of the problem? Kernel? Modem? How to debug it?
Maybe the problem is with modem version? I have OL1.
I'll try to collect info into this post...
Possible solutions:
This solution on darklord's N7 modifies etc/gps.conf.
This post reports good results with the app GOS location tracker.
This post from AryaMod reports good results with custom gps.conf. Though this post says that the app GPS test still has lock problems.
This post claims the problem is solved by adding "CAPABILITIES=0x11" and hashing out ON_DEMAND.
I tried the CAPABILITIES=0x11 solution on "TouchWiz Marshmallow for Note 3 (V4)", and Arya, and still got flashing GPS lock.
I tried the new "Darklord with all fixes, gps fixed", and GPS still has a problem.

I think this is not a problem specific to N900T, which is why I'm asking here to try to see what devices have the problem... On the various marshmallow ROM threads I don't have the impression that it is a problem just for N900T.
But I have one.
I understand. I have a Note 3 running a stock ROM so I can't offer any possible solutions. Good luck in your search.
Maybe the problem is with the Modem version? N900T has a fairly old modem, whereas N9005 have newer versions. Maybe those that have newer versions installed have no problem, but older ones do, or vice versa? Please report what modem version you have...
I am on n900w8 and I have the same problem. I've tried n900t roms n9005 roms ive tried changing the firmware on my note to a older and newer canadian version. I noticed this problem starting on 6.0.1 never noticed it elsewhere. Its a real bumer.

Im using n9005 on phronesis 6.0.1 n7 port v4.1. Tested on latest modem with lsskernel 3.5ux and 3.8 ux with no hit... only get gps location but cant navigate as no glonass satellite fix... anyone has same issue?
Modem should not be a problem as GPS is on kernel .
Modem or wiFi does give A_GPS .
if you read the forums you will see many models saying GPS does not work on MM .
Fixes are many and varied .
Problem appears to be the simple fact that its a port .
Me N9005 custom rom various and never had a GPS problem .

Hello,
as I am completely new to Samsung, I have got a question regarding the different basebands.
My S4 is running XXUAME2. New custom Roms are using different versions (for example XXUBMF4). and what is a CSC?
I couldn't find information if it is important to stay at the same baseband version, wher the differences between the basebands ar.
Can anybody please explain me?
Thank you!

I would also love to get the answer to this question +1
Thanks
Basebands are the same as the radio. They can improve your signal, and i some cases even affect other things like camera quality.
Newer basebands are nearly always better.
CSC is country code and you should try to find a code with your country
makhakz correct me if im wrong but csc's and modems are two different things altogether. my advice would be to leave csc alone as its allready set for you and just flash a different modem.
some modems may increase speed and connectivity others may improve these.
its a case of trial and error really as to which one works best for you
Hello everyone
I wanted to ask you a question about my device's baseband.
Currently I'm on CyanogenMod rom version 11, which I installed via the installer (since it looked so fast and easy).
I moved to CM about 2 months ago from the BTU version of baseband I9505XXUEMK8.
I do not have any reception problems but I saw since this baseband version there went out many other versions (including the new baseband version for the leaked Kitkat).
I do not want to have future problems and I feel "guilty" on being on an older baseband version so my question is when do I need to change the baseband version? Only if I have reception problems or in other cases, too? And in which cases?
Thanks in advance
If everything is working fine then there is no need to change. Usually people would change if their network releases a new modem as it's better to be on the recommended modem used in the original firmware by your specific network or if people are having signal issues. All models work regardless of rom. I've flashed many modems and all have worked fine find the right one and stick to it.

So as I said, I'm on I9505XXUEMK8 modem almost 3 months (from the moment it was released for BTU, but I'm from Israel not England).
As far as I understood, I can stay on that rom as long as I don't have any problems right?
Correct. You'll be fine with your current set up.

Hello guys. I have the n900t, I am now running tweaked s5 base n4 style v6.0. And I run alot of n9005 ROMS as well. With that said here is my issue. For only the past few weeks ( month tops) every time i make or recieve a phone call my data drips down to hspa. The second i hit call and right before my phone rings is when it happens. After my call the data takes a very long time to jump back up. This is a new issue and i have no idea what it is. However, i did flash back to a stock ROM and the issue was solved. And i forget which rom it was but it was soley TE based and there were no issues. I did try to flash a modem but it didnt take. Is anyone else experiencing this problem? Or can anyone suggest a fix for it.
Thank you for your help.
bump.
Still having the issue. I tried to flash a new modem and it just failed anyway. Dont know if I should try a radio. I just cant fivure out why this happened out of no where. I was fine no matter what ROM I was running. Now...this crap. Please guys, 40 people saw this, can SOMEBODY please help.

1) Quite strange - your picture suggests you are on Verizon yet you comment about a N900T in the forum for the INTERNATIONAL Note 3. On what network are you? Are you aware that there might be network-specific factors involved which could only be visible for other users on exactly the same network in exactly the same region?
2) Try stock ROM (with corresponding stock modem) from a location with very good signal.
5 he physical device is an n900t, however, I am running as of now, the hyper drive note 5 port with n4 UI. When I do flash back to a full stock TW ROM all is good, A FEW TW based ROMs seem to be OK. Like this one, the calls do not affect the data signal. But most ROMs do effect it in that way. You said that it shows I'm running Verizon?
But I am very curious why all of the sudden I am having this issue. I have never had it before. Except with a few specific AOSP based ROMs. I just can't figure out what it is that's causing it. I have done vigorous wipes of the phone to no avail.
And I am in Philadelphia so there really is no place that is actually bad reception (except in the susubways of course...lol)
And thank you for your reply.

1) Your avatar mentions Verizon for some reason.
2) If it is all OK with the stock ROM then it is a problem with the custom ROM, ask in the specific thread for that specific ROM. Most likely it has something to do with the modem and the corresponding RIL.
So when ever a new ROM is flashed the modem is flashed as well. Unless the dev says otherwise?
Hey guys, a few days ago I bought from ebay a used I9502. It came with SVA rom with android lolipop 5.0.1 preinstalled. I like the rom very much but i have a major issue. It is impossible to find my location using only wireless networks (wifi, 3g)(power saving mode). It can only find my location when using GPS and I am outdoors (high accuracy mode). I have tried to reset to factory but nothing changes.
Do you know what may cause this issue?
Thank you.
update
I have an update for those who might be interested.
I flashed the latest stock rom from sammobile to see if the problem continues. With the stock rom the location servicve works fine.
After a reseach I figured out that the SVA rom is missing "NetworkLocation" that's why it wont find my location using wireless networks.
The problem is that I discovered that the version of "NetworkLocation" I have, collects and sends data to Baidu(something like the chinese google). So I was wondering if any of you guys using an international lollipop Galaxy S4 would like to help me and send me his version of "NetworkLocations".
Ok I'm just a little confused.
Canadian i337m compatible marshmallow roms?
Are they jflteatt jfltexx i9505 or something else or all of the above.
(I'm running wamanlite 4.4.2 9505 rom now on my jfltecan I don't think there are any good links for it left, and when I flash a new one there will be no going back)
I know there are others confused out there as well..
If you are using marshmallow and you have flashed the rom to your Canadian s4 and all is working great.
Please post a link to that rom here
If you needed some other kernel or file to flash in to make it work
Please post that info with links also.
Thanks for any info you can provide.
(And bite me Samsung att and others for locking so many U.S. carrier boot loaders which has reduced development)
The s4 should work with the 9505, jflteatt, and jfltexx ROMs; however, editing the updater script may be required to get the ROM to install.
Hahaha - you will likely get yelled at to use the search bar and to read the stickies with these sorts of questions, but I was a noob once too, so here's an olive branch. (that being said, please do use these in the future!)
Your i337m will be cross-compatible with ALL GS4 devices (at least to my knowledge). I've had one now for a little over 4 months and have explored most of the options available to the Canadian variant. I have run everything from 4.2.2 to 5.1.1 on my device successfully, but you will have the most luck where the developer indicates that the build is for jflte devices in general, not one in particular.
Furthermore, the GS4 or ANY device sporting a Qualcomm chipset can use a modified modem file to access WCDMA/HSPA bands (ie. WIND, or T-Mobile).
Again, the search bar is your friend here! Also try Google, or Duckduckgo (google will tailor your results, sometimes in a way which will actually hinder your search).
If all else fails, send me a PM and I will assist you wherever possible.
Best of luck!

Just wondering what modem to use. Do I use the latest modem for I337M or can I use modem for I9505. I live in Canada and have always used the modems for the I337M model. The latest modem is PA1, I think for the I9505.
Hey tvsite,
Modems for this phone in Canada puzzled me for quite some time, however, this is what I did to make things work.
--> Downgraded from 5.1.1 CM 12.1 Optimized via odin using "I337MVLUAMDJ_I337MOYAAMDJ_VMC.zip" (http://www.sammobile.com/firmwares/download/14412/I337MVLUAMDJ_I337MOYAAMDJ_VMC/)to net me 4.2.2 (note: your wifi or calling WILL NOT WORK).
You may have even better luck using the SaskTel firmware at this point, although I have not tried it yet. (http://www.sammobile.com/firmwares/download/14418/I337MVLUAMDJ_I337MOYAAMDJ_BWA/)
--> Do the AWS mod, unlocking etc.
--> Upgraded to 4.4.1 using "I337MVLUFNC1_880525_REV06_user_low_ship_MULTI.tar"
https://mega.co.nz/#!h8pTnCZS!t2-PiSb5W9ZyNp7fct7WD_Pg_dnc-eZqtMvpsuKv_9Q
--> I forget what modem I was on at this point, however, after letting OTA do its thing, I wound up at 5.0.1, OH1 modem, and AWS still enabled.
Good luck!

I flashed the OK1 modem which is posted, here, which is for the I337M model. I believe this is country code Mexico. This modem is working fine. Have you tried flashing a I9505 modem using Odin. I tried and it said "failed", so I may have answered my own question---that you cannot flash modems over different model numbers even though its the same phone, ie. S4
