First, please forgive me if this is the wrong place, but this is the General Forum, and the forum software has changed a lot since when I was really active here as an active phone modder and active poster!
So like I said I've been away from the forums for a long time... trying to rereading a lot and trying to get back into MY PHONE.
I hate my modem sometimes because T-Mobile just sucks in some areas and is great in others [Greater Houston Texas Area, but mostly south side and towards the Galveston Bay].
I would like to know if the newer modems are interchangeable with the below config on my G900T?
And if there is any advantage to upgrading my modem? Wondering what modem I might be able to upgrade to with that below config and if there would be any advancements/pluses/gotmeinabadways/or other things I should be aware of if I did?
Also I'm wanting to upgrade to Marshmellow maybe, should I or should I just forget it? I will be reading more about the ROMs available. I've read a lot of posts about how buggy 5.1.x is. So I don't want to even go there...
Basic Phone info, Stock T-Mobile ROM [Damn bloatware] rooted awhile back with I think towelroot. I would really like to change to a slicker ROM that is debloated and maybe deoxed maybe. Will have to read hella lot more about that for sure..

Can anyone recommend an app that will give modem info without having to decipher the baseband? or is there a very good break down of what each part of baseband means? I know go search!!! and I'm trying to reacquaint myself with the forums but the newer software is far different than I remember EKK! And search always hated me!! And even the different forum headers have changed due to time marching on and me being well Techtarded the last year or more due to things better left unsaid...
Have Xposed installed as noted above, but its been f00ked for a long time due to the ARM processor if I remember correctly and the Framework installer not being compatible..... Wish I could used the Xposed but........ I originally got into Xposed due to the Hex icons I actually paid for Xposed because I liked and used some of the modules made by smart people. Again but!!!

The most recent firmware and modem for the TMo S5 is version OL1,that came out in late December.
muniz_ri has been nice enough to put together a ROM that is the Stock ROM, already rooted, and ready to go:
http://forum.xda-developers.com/tmo...t/how-to-update-to-g900tof6-5-1-1-pc-t3141404
There are links there to the ROM, including the modem, or just the modem files themselves.
Rob
@daspazz the following website has decent basic info that seems to address the questions you ask: http://androidmodguide.blogspot.de/p/other.html
TLDR: yes modems are interchangeable
As for Marshmallow, I'm pretty sure for now, since there has been no official 6.0 update yet, you'll have to go with Cyanogenmod 13 (or one of the variants like Bliss 6.0 or Resurrection-Remix), they're in the unified development section (our phone's development codename is KLTE).
As for deciphering the baseband, look at the last three characters, let's assign them generic letters XYZ. X is the year (M being 2013, N being 2014, O being 2015, P being 2016, etc.), Y is the month (substitute the actual letter for its position in the alphabet), and Z is the revision number. So taking the most recent firmware (G900TUVS1FOL1) as an example: OL1: O means 2015, L means December, and 1 means 1st revision. Another example, build number G900TUVU1ANE6: NE6: N means 2014, E means May, and 6 means 6th revision.
It seems to me there's been some consensus that the most recent modem (which rlichtefeld linked to in the post above mine) is the best
Much Thanks!!!!
@rlichtefeld and @thisisapoorusernamechoice
I really appreciate the information gentlemen!!!! I've been reading through the info you both provided.
I did flashed my modem (only) to the newest one, G900T_OG6_Stock_Modem.tar. Ended up having to flash back to the modem for 5.0, G900TUVU1DOB1-MODEM.tar, because I literally could not hear anyone when I made or received calls.....
Also had to used Odin v3.09, because v3.10.6 wouldn't recognize my phone. Strange that!!
This ADB installer was very helpful!! It fixed problems I was having on the PC I was using to flash my phone. Much thanks to @Snoop05 for the ADB installer for the PC. It keeps you from having to install the full SDK for Android.
Thread moved to proper forum.

Am I missing it or are there instructions to root and instructions for multi-boot but no ROM for the LG G Vista, please?
I've searched and read through a bunch of threads but nada ... so far.
Will any of the ROMs for other LG G-series phones work?
Thanks!
Wait ... I just looked in About phone and it says this is a VS880.
I just got this from Verizon.
I'm seeing the VS880 referred to as a G2 and a G3 on the Internet - what is it really, please?
It came with Android 4.4.2, kernel version 3.4.0+, and our son rooted it for me earlier today.
Just in case any of those details help ...

They are the same thing. One is the internal name while the other is normal users name of the device. As for roms make sure to do your reading up as the device is pretty locked down.
So, you are saying that there is no ROM anywhere for the LG G Vista/VS880?
Is there any reason to believe that anyone is actively developing one?
There are so many sites touting Rooting as a pathway to loading a ROM it seems odd there there is not one.

It takes more then root. You need an u locked bootloader or a way to bypass a locked bootloader like safestrap or bump. Most developers that make roms only make them for devices they own.
The bootloader bypass has been solved:
http://www.unlock-bootloader.info/mp3-0/lg-g-vista-6569.html
The LG G Vista/VX880 is "free" on Verizon with the $16/mo Edge data plan & has a nice big display.
I have my Samsung Tab4 7" tablet for sale as I don't need it now that I have the LG G Vista/VX880.
There are ROMs for the models all around the LG G Vista/VX880 - it's hard to believe that LG made that phone so radically different from the others that tweaking an existing ROM to port it would be beyond a developer.
Sure wish I had the skills ... sigh.
It's not really that. It's most developers seldom do ports. Let alone for devices that don't have. After looking at the spec is not a bad mid range device. But also remember that. Most carriers in the world are GSM carriers and very few work on cdma devices.
There are plenty of Tuts on how to port. Could be something you could look into

Modified request: Is there an app/hack that strips-out all of the Google stuff, especially their backdoors & data-leeching?
If no one is going to build a custom mod - which seems apparent - it sure would be good to have a clean machine onto which to then install carefully selected apps.
Thanks!

Simple answer is no. You would have to build a rom from source and then remove alot of the Google based code. There is a project that is working on it but you lose alot of functionality.

Cannot the functionality be restored via privacy-respecting alternative apps?
What about an app that monitors the bad behavior of the Google code than cannot be removed and blocks execution of data-leeching & activity monitoring?

Not completely no. Many have been trying over the years. Your biggest issue is the device your using. Once that is taken care of you can try and build something but like I said alot of the stuff is built directly into the os.
To be honest privacy is an illusion at best now a days. Every thing monitors what you do. From credit cards to social net networking. It is all made to get as much info as it can about a person. Even carriers do it. It has even come to light that Verizon can monitor the apps installed on a device.

Many Many hours wasted on Google,Bing,ect. I haven't found anything. I have seen where some people refer to this as the same as a G2 And others but it's clearly not. But yeah wish someone would put something out. Agreed. I have however figured out how to get Viper4Android and Dolby Atmos to work. So if anyone is interested in knowing how that's done hit me up. All you have to have is root. NO custom recovery. Haven't seen a post on how to do that either? I still have 8 more to go before I can post lol.

Where did you get the rom? Do you have a copy I can get?
Howdy all!
What is the highest OS build rom that is availble for the Springboard/303? Is it as high as 4.4? Maybe even 5? I have looked but cant find a conclusive post on what is a good and stable build for this tablet. I am running 4.01 huewei image right now.
Thank you!
For the unbranded S7 it was 4.03.
I don't whether custom roms can be flashed, but these range up to 4.4 only. The late roms of Zyr3x, the last dev, who got banned on XDA for selling his roms, had severe issues, there wasn't anything useful since spring 2014. So check the old threads for hints and links, which still work.
Any suggestions for a 4.4 rom? I searched through the forums and didn't find any that seemed to apply.
Anything up to May 2014. I'm not sure, but didn't Kitkat start with 4.3.x? In May/June Zyr3x began releasing CM11s based on a new source, which would self-destruct after a couple of reboots. I never found any evidence that these roms were working longer than a couple of days for anyone,so it was not my fault, that this happened with any new version, and an early CM12 by the same dev. With CM11 even with the smallest possible GAPPS there was only 1 to 3 MB free mem on the tiny (350MB) system partition. This was probably the cause for instability.
But I'm not sure whether you could use any of these roms on the Springboard. The free S7 has no locked bootloader, probably you first have to unlock that on the Springboard. If possible.
I'm using the 4.4.4 released from zy3ex. Some time (not often) reboot and loses something in the data partition, usually some app config.
The bluetooth has problems.
Anyway I'm satisfied.

Flash custom ROM
Video with links to files, and other hopefully useful info. FOR A SOLUTION!
I had a really long post with useful info containing an answer maybe not "the answer" Wanted me to instead post a comment.. Below are the instructions on how to do it according to a Youtube Video I found. While I haven't tried this method, It looks sound to me, they've included all the files needed in a link to MEGA. I'll re-share without the password / decryption key if the poster agrees only.. I do highly suggest Phoenix ROM if you're on a kltevze, it come included with eveyrthing you're looking for and I've used it before In fact, I tried it last night but was unable to get into my phone past the boot password screen I think because the system ui kept crashing. while I have used this version, I may try twelve, since I prefer AOSP or LOS based roms, I want as light as possible maybe even removing google and going with MICRO G which I used fairly successfully for over a month, It isn't perfect, sometimes the location addon apps crash, but there are many, and it may just be that the ones I was using crashed, and not the ones you need yourself.. But MICRO G is worth the piece of mind to me coming from an encrypted phone, No I have nothing to hide really but Alphabet/Google already know enough about me through the use of their "FREE and Very Handy I might add, Services Ahem) By the way, Phoenix can be used with either an unlocked bootloader or safestrap if not.. Just get the right one.. I may end up going with a rooted deodexed TW rom, and add xposed to get the features I love from RR and other LOS based ROMS. With further ado, heres the link to the youtube instructional video I found, I really wish it was written out or could simple installed as a flashable zip which shouldn't be hard to make, but it is what it is for now.. And again seems correct to me if you don't want o go with a custom rom like Phoenix for kltevzw.
Well upon testing the Youtube link didn't play so here it is both Title for searching and another link. Install Galaxy S7 Touchwiz on S5! (Marshmallow) /URL]

I used Heimdal to flash to a more recent factory TW before flashing Phoenix which requires at least PB1. I think. Check their OP under user JKRUSE or near the top of the VZE dev thread.
This is Heimdal as found in synaptic from a buntu based distroand should be the same in any Debian based or any other distro for that matter as I've found it in many repos for different distro's, I think a ppa is available with newer builds, but don't hold me to that.
Heimdall <- commandline version.
Heimdall is a tool for flashing firmware (aka ROMs) onto Samsung Galaxy S
devices over a USB connection. It accomplishes this using the same
protocol as Odin, Samsung's internal Windows-only firmware updater.

If I do either agian soon, I'll report back with results. Again, I know Phoenix worked fine. But I'd imagine a plain TW rooted ROM that you debloat yourself and maybe add Xposed for many features found in Phoenix and in AOSP/LOS based ROM's such as RR/CR-DROID for those who prefer additional tweaking and other enhancements. Again I trouble just last night with the latest V15 of Phoenix on boot and don't know why other than my fully ecnypted device and password on boot feature But either way again if you test before me let me know the result as well. I do need a new battery for mine since it's the one it came with but that's a story for another thread, when I bought my S5 last spring for beans, (with the unlockable BL, I had to have it since my S3 had died. and I couldn't afford a new phone) and I could easily get a day plus when service is good with about 4+ hours SOT. But lately I'm using charging by the end of the day. Haven't decided yet on a stock Sammy battery or a more expesive, Thicker, heavier, but much longer lasting extended battery.
Sorry for such a long winded post. All my posts are this way if you know me. I do apologize and need to be more brief but I'm more of a lurker and searcher for what I need to know and post very seldom especially with this much what I think could be useful to someone.
If it happens to be useful please hit the "Thankss" button, it could help here, and even when looking for a job as I am... Hahahaha.. Getting laid off work blows in my area of the country.

IS THIS FORUM "DEAD" or something?! I've been BANGING my head against a WALL for about a month now trying to fix an apparent "Sms over Sgs" function being disabled on my N910P running LineageOS, if I use anything but a stock OS I'm not able to "send" SMS unless I switch to 3G. Does anyone possibly have the following files kicking around? The links to them are dead everywhere I've looked. That or any other bright ideas? Do I need to flash the baseband again after installing Lineage or something?
Aurora.N7.Port.v2.1_data/sms fix for Sprint
Aurora.N7.Port.v3_data/sms fix for Sprint
Hya! So I am in the same boat... I am trying to do research... So far I have not been finding anyone with answers past the N7 Port. I cant even seem to be able to install the ROM cuz I am on Q15 Baseband. I udnerstand that you can't downgrade once we committed to the latest.
I also am having huge bluetooth crashes. Trying to keep attached with my FitBit and keeps dropping.
Lets see if we can find some answers together!
I tried the download of the SMS fix for Sprint and flashed it but doesnt seem to work.

Think I've tried them both already, I've gone around in so many circles it's hard to keep track...
I have learned one key through my digging, seems most things need to "match" the same generation for the OS used.

Unfortunately those links were dead the first time I tried them a few months ago... Thanks though. The only real shred of hope I seem to have left is an older post that someone apparently flashed the baseband files from the last OS that "worked" and they got things functioning on the newer OS. Now I just have to figure out how to flash the baseband separately from the OS?! I think I can do that with Heimdall?

I thought we couldnt go back from the QI5 firmware... or did I miss something?
This really seems like a super simple solution that shouldnt be this hard. It really must be a software problem. I am super aggrivated ... probably like you.... that such a great hardware platform is being rendered so inefficent. There are no new phones that have the ability and versitility of this platform and I am committed to keeping this hardware for years to come. I dont need it to do a lot... I just need it to do the few things I require of it! I am thinking of starting a new thread in the sprint forum to get some current and collective knowledge of the best setup available for the N910P
Hello,
I recently acquired a refurbished S9+ and as many other people, I realise now that someone must have been messing around with the internal software. This is my secondary phone so it's no big deal but I would like to understand what was done on it nevertheless, and maybe turning it back to a cleaner state, if possible, and if it has not too many drawbacks.
-apparently, Samsung Pay is not working. It hangs indefinitely on the screen where you must choose the type of security.
-when looking into the Play Store settings, the device is not certified
-WiFi calls apparently are unavailable
-OTA update is not working (nothing happens when I try to check for an update manually. What's more, no information about the last update is available. By the way, the phone software is outdated. (last Android security fix is dated from Feb 2019)
From what I read, it looks like the CSC was modified, right ? Would it be a good idea to change it back to original ? (I may need some guidance about that but we are not there yet) Would such a procedure restore, for instance, the OTA update feature ?
(see pictures attached - there is what is written on the phone's back cover too, if it can help)
Thank you very much in advance. Please tell me if you need some other specific screenshots.
PS : I also bought a Note 10+ from the same refurbisher and it ended up being a Korean model. But the firmware seems clean. I know Samsung Pay won't work in France, WiFi calls either, and I will be stuck in "LTE" 4G instead of 4G+ but at least OTA updating is functionnal (I got an update a few days ago) and honestly ? That's fine with me for the price.
Anyone ?
From what I've read researching on similar issues, the previous owner who messed around with the internal software must've flashed custom firmware on your S9+, and probably tripped Knox (and is why your Samsung Pay app won't work). According to some developers on here, you're able to hide the fact that you've rooted the phone, but I don't think you can un-trip Knox once it's been done.
Prior to your post, I didn't know a single thing about CSC and I'm not sure how it's really relevant when flashing a mobile device (unless it's carrier-related), but I think all that's required when flashing a device is the model number. Luckily, I stumbled upon a thread that is actually your exact, same model! Do what you please with it, and I hope I helped — I'm not a professional, nor am I really knowledgeable about all of this stuff, but I'm trying.
This is the thread I was talking about:
Official Stock Firmware Thread (11 August 2022) - Galaxy S9+ (SM-G965F)

You're welcome! Was it what you were searching for?
Not sure, but I hope it will help me understand the firmware/CSC stuff better
Alright so apparently this phone actually is a SM-965N, judging by what is displayed when booting into download mode.
Unfortunately I only saw this after starting a flashing attempt with Odin and now it's stuck at "system.img" so... I'm gonna let it run a few more hours but...
It's most likely bricked at this point, isn't it ? (edit : interestingly, after I forced-closed Odin and reboot the phone, it was not)
If you ask me I find this kind of "refurbishing" a little bit sketchy to say the least.
