[Q] Installing another S4 carrier's modem - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have an I337 running on tmobile network. I have tried both tmobile's and at&ts roms and both get 4g but the att&t rom seem to connect faster. I am currently on mdl modem and woul like to experiment with tmobile's modems and am wondering if it is safe?
Thanks in advance

I heard doing this could possibly erase your IMEI number. Personally, I'd only flash my carrier's modems. Just to be on the safe side.

Its not wise to use other carriers modems, and it will clear the IMEI, but I have heard that it can be done. Kinda of a hit and miss thing, if you are going to pursue it, backup your efs first.

Your welcome, and trust me, do not get into the IMEI restore thing, you talking about a pain, try that once.

good choice. in all the diff radios i have flashed on various phones they gave no more than minimal improvement if any
i thought initially the mf3 radio was better, now not sure

I hope I'll never have to go through that but if I did, can you share the steps? With my s3 (may it rest in peace) a simple "reboot nvbackup" and "reboot nvrestore"command in terminal emulator was all it took, and it saved me many times. Would this also work with the s4?

You're right that has been my experiences with different radios also.

replacing the IMEI, talk about a hardline approach from Samsung.
I remember on my S1 flashing radios from S1's all over the world, Europe, China etc etc
Though thanks for this thread, I was actually wondering about flashing a canadian modem, to unlock AWS and since it's one build higher than the AT&T modem

Just a reminder, it is not wise to run other carriers modems, the modems we have are sufficient to do what you need, and if you find a way, you will not see much of a change if any.
Good luck to all.

Hey man, i am starting to think i would have to flash another variants modem on my s4 m919v because i dont see any modem files for my phone on xda or atleast i cant find many because this variant isnt all that common. What do you think its possible right?
Oh and the reason i want to flash modem is because i want to flash an older modem for s4s that allowed them to be unlocked using the *#0011# code and i cant do that currently. I have heard flashing an older one will allow me to unlock my phone.

Unlocking different LTE bands.

Hey,
I ordered and received a N9005 unlocked version. I am on Bell network in a city where they use AWS (aka Band 4, aka 1700/2100) and (this is my bad for not checking carefully before ordering) this version doesn't support those LTE bands. It obviously connects fine through hspa+ though.
So, I was wondering, since the hardware actually supports those bands, is it something that a hack could unlock in the future (be able to use LTE with this phone on this network), or am I just gonna have to live on hspa+?
I purposely put this in general as I believe the discussion that this could drive would make it more fitting than in the questions forum if this is a possibility.
Thanks,
Math

LTE compatibility has been discussed in so many threads, you really should do a search before posting next time. If your phone has unlocked bootloader just flash Bell's modem onto it, once it becomes available. Or ask a friend, who has Bell branded GN3 to dump the radio for you, and take the firmware from him. Qualcomm's MSM8974 chip does support all LTE bands worldwide: http://www.qualcomm.com/snapdragon/processors/800

I usually do make a search but through all the threads relating to various questions regarding model variations and other questions relating to LTE, bands, compatibility, my search rendered very little insight to my specific question (although I'm sure it was answered before as you say, I just wasn't able to find it through all the other stuff relating to my keywords). And as you can see from the answer above you, I wasn't able to trust some answers that I managed to find.
Truly appreciate your answer though, Thank you very much and I'm happy to know I'll get LTE again soon.
Thanks
I too am waiting for a modem with 700/1700/2100/2600 on the LTE side. For the Note II this was done using Qualcomm's software to instruct it to use those bands... Rogers, Telus and Bell are all launching tomorrow on October 4th - sometime after then I hope to see the modem online and give it a whirl, but I suspect we might need a QCN file change also.
There is hope!
Got us a little closer: On my N9005 - *#0808# will bring up the Qualcomm USB settings.
On the Note II and S3 this is usually *#7283#
We're getting closer! Those with N900S / N900A / N900W8 phones, feel free to dump your NV Params QCN file now using the Qualcomm QPST Software!
bump!
No real luck yet. I can't flash N900W8 firmware onto my N9005. Neither the whole firmware or just the modem.bin.
Editing the NVParams didn't really work either, as some we tried just get reset to default after a reboot.
I flashed a N9005W8 modem (using dd as root) and unfortunately, it fails to communicate. Baseband shows as unknown. I suspect only a NVRAM dump with removed imei will work. Otherwise modem will need to be ported properly.

bump.... looking to find out how i can pull the modem file out of a specific firmware file, such as pulling the modem file only out of the bell tar file and then making it flashable with odin for my wind phone? i am downloading the whole bell firmware right now and am going to try to flash it on my phone..... i already tried the puerto rico one and it works, but with bell i only get hspa i assume that the bands bell uses are different than the PR ones. i do know that someone has already stated that they got rogers bands with it, but not bell yet, i dont think....

What does that bin contain? Your sayin that is necessary when i flash the modem? When i flash other n9005 modems i dont flash it.
In either case i dont have a copy. Upload and ill try.

Download the entire N900W8 firmware for odin. The modem and many other interesting things are within.
However unless you know something i dont, you will soft brick your phone. Assuming you are able to flash at all. (odin will not reject the rom)

Do you think in the future they will extract just the modem and I will be able to flash that separately? On the S3 I remember being able to flash different modems with the latest CWM.
Right now I have an unlocked n9005 with the Baseband I quoted in my last post. I am using it fine on Rogers Canada lte but in some places the signal is weak and I will lose connection altogether. I was hoping flashing the modem for my provider and region might fix it since the s800 has the correct frequencys for Rogers I think some are disabled or not being used because of software (it was an Asian model I think with a csc for a different region). To reiterate it does work on Rogers I was just hoping I could fix these network drops by flashing a more appropriate modem.

The modem is simple to extract, just untar the odin package.
The trick is actually making the modem boot.
The PBL appears to reject the modem, and thats very bad news for this concept.

bump, is this possible yet?
Just thinking out loud here, but I wonder if flashing the Canadian csc file would be helpful here? In the stainless rom thread in t mobile the op has the Canadian csc file posted. I wonder if flashing that first would allow things to boot with the w8 modem?
I did some thinking, and since you are trying to get a band working that the Snapdragon does support natively, maybe there is a chance. I would hazard a guess here, after some research and guessing, that the antenna actually would work here, so it could, in theory, just be a matter of firmware. Unfortunately the stock modem for the n900w8 may have to be modified to work....Not sure there. But may be an idea to flash the Canadian csc then flash the modem and see where that gets you? Not responsible if your phone bricks cuz I have no idea if this could work, as I said, just thinking out loud
Any updates on this? I too am interested in getting LTE on my n9005.

Galaxy S4 Reception - Flash New Radio?

Ever since I got my new Galaxy S4 (Fido) the other day my reception has been less than expected. I get 1/2 bars in a room in my house where my previous phone (Motorola Atrix 4G) had full bars. I already exchanged the phone for another S4 and the new one has the same issue. The only constant is my SIM card which I will try and replace, but if that doesn't work are there any reliable radios which can be flashed on the S4? I know for the Motorola Atrix 4G there were some better radios compared to stock which gave me great reception. If this is the same for the S4 can somebody please post a link to the radios I can try? Thanks!
You should flash the modem appropriate for your region. There is a big modem thread in the General section with lots of resources available to you.
Thanks for the reply! Although I can't seem to find the Canada modems for the i9505. Canada isn't listed in the firmware checker link provided in that post. Can anyone recommend or let me know which modems are compatible with a Canadian i9505? The baseband of my phone right now is l337MVLUFNC1.
Thanks.

I'm not sure what you mean exactly. I haven't flashed anything on my phone yet, it's all still stock. I'm waiting to flash a new ROM and modem since when I do I can't bring back the phone anymore and as of right now I'm thinking about returning it since I'm having bad reception. If someone can tell me for certain that a specific Canadian modem will give me good reception then I'll be more likely to keep the phone.

1. Your phone is OK if you go outside and you have full signal.
2. You need exchange ur phone if you go outside and you have low signal.
3. Don't ask me again if you can flash other modem. With 3 times is enough.

These are my only unlocking options?

OK, I just come across an S4 SGH-i337M running 5.0.1 locked to Bell. Searching Google is fairly mind boggling as everyone has their own method. In my situation, I'm pretty sure I have come to this solid conclusion. Two options only,,
1. Buy unlock code or
2. Downgrade to at least 4.4.2 and use the hidden codes method.
Can #2 be done safely? Some sites say if you do try downgrade from Lollipop to KK, it will brick. What would a safe procedure be if possible.
Thanks

Thanks, seen this but wasn't sure. I assume that flashing back to Lollipop isn't necessary if one chooses to stay at 4.4.2 for a while. Heard some comments about increased battery drainage etc. on Lollipop.
Will try this once the new charge port shows up and I can replace.
The hidden codes method won't work, unfortunately. Let me know if you are successful.

Thanks, will do. Hopefully will be getting to it tonight. Here's one of the confusing things I was talking about. Been doing alot of reading, and in your instructions, you install TWRP to flash SuperSU and such. Then, reading elsewhere, I see this "SAFESTRAP IS THE ONLY RECOVERY WE CAN USE!
Don't even try flashing another one.", posted in a thread about AT&T SGH-I337 model. Well, here it is, halfway down in the second post, bolded in red. http://forum.xda-developers.com/showthread.php?t=2616221 Just trying to get things figured out, it's been a couple years since I last played with the Galaxy, just getting back into it now.
The AT&T version of the s4 is the Sgh-i337 and, if it was running stock 5.01, the bootloader would be locked and twrp cannot be used.
The Canadian version of the s4 has the letter "m" at the end of the model number and the bootloader is not locked which allows the installation of twrp and custom ROMs that are not based on a tw kernel.

Thanks, this method seemed to work,,just one problem I overlooked, but I just assumed this phone would work on AWS1700,,wrong lol. I was reading the 141 page thread and there seems to be a few different methods for doing this. With my S3, I only had to flash the NV and run a script on every boot as the nv rewrite would not stick. Is this so as well with the s4 too,,or is there a method to make it a permanent stay. I didn't plan on updating to 5.0.1 quite yet,,but will do if needed. Do you no of a recommended/preferred method for this?
Did you test the phone with another sim card? Hopefully, you will not be prompted to enter a network unlock code.
For AWS, I'm not sure what needs to be done as I am using a Telus s4 on Bell.

It was locked with Bell, my provider is Eastlink,,I finally got the AWS1700 band working, but kept losing it when the phone went to sleep. Updated to the NE1 modem, then had to flash the AWS again and all seems to be working fine. Hopefully it holds up. Thanks for everything.
Glad it is all working. We're all here to help and learn from each other.

Difficulties after switching to T-Mobile

Hey guys! Thanks in advance for any help or clarity you can provide.
I had to switch to T-Mobile from Verizon. My device isn't rooted, modified, or in any way different than factory. However because of the switch I've had some functionality that I've lost. Namely the ability to get software updates. This phone has been rooted before, and I'm very comfortable with the process of loading up different software. The question I can't find anything on is whether or not installing the T-Mobile firmware will brick/cripple the device. I know there are different chipsets so I'm trying to figure out the best way to keep my phone up to date without being on Verizon anymore.

I tried finding something about loading the T-Mobile firmware on a Verizon device but I haven't had any luck. Only guides on doing a regular firmware update on a T-Mobile device. Should I be worried about the Exynos/Snapdragon differences? I hate asking for something so simple, but could you please point me in the right direction? I'd LIKE to try and go that route, because the U firmware had poor battery life, a lot of heat generation, and requires a patch just to get wifi to work. Then again maybe I'm thinking of the eng boot we had for rooti. I do love my all day battery quite a bit.

T-Mobile, Verizon, and the U phones all have snapdragon processors. No need to worry about that.

Just look on the forums on flashing either the U firmware or T-Mobile firmware using Odin. It's a fairly easy process if you read through the steps thoroughly. And you don't need to worry about unlocking anything.

I'm familiar with flashing the U firmware, as I did this on my Sprint s7, but my understanding was that just flashing the U firmware didn't open up the bands. But are you saying that flashing the U firmware alone was enough to get TMobile fully working?

My understanding it does. The hardware between the phone's should be the same so it's software that's affecting it. But the U firmware won't allow wifi calling and other carrier specific things unless you're rooted. So pick and choose.

ls997 to us996?

is there anyway to fully convert it? I got a sprint version for a really good deal and im on att. Or atleast flash the modem or does it do that when you flash that rom?
I can unlock the device for you, I have another free slot available.
Message me on skype: stoney.lawson
https://www.youtube.com/watch?v=fFl8_FDffp0 for video proof
Okay, I did. but would it matter if im on the us996 rom?
If you're on that rom the device is unlocked
Well then the real question is can i flash the modem that goes with the rom? or would it brick it for my purposes?
Flash the entire rom from the dirtysanta thread..
have you done so already?
I did. I know it unlocks it but what im asking is does it flash the modem with it? searched all over couldn't find if it did or not.
I'm not too sure, it's all in the carrier settings in the software, you're fine and good to go, don't stress it any further

Well really im just looking for the modem. Looks like he flashed the entire KDZ. Does anyone know if just the modem flashing would work?
Actually he performed US996 KDZ flash got no signal - than flashed directly DD part of LS997 modem.
The problem is that EMMC partitions are different and with different start/end address locations so you are hard-bricking your device this way when you overlap them and the only way to restore it is low-level via JTAG.

Click to expand...
Click to collapse
Well this kinda sucks lol stuck with using us996 roms because somehow it unlocks the device.
I really can not understand why are you thinking that you are stuck on using US996 ROM only...
If it is about SIM lock - you can easily unlock your device...
yeah but if theres already a way to unlock it (meeting requirements) without paying then why would you pay for it...
