I just bought a Samsung Galaxy S3 i747 from Amazon. It is an unlocked GSM version.
Problem is it has a Canadian baseband version, and I am in the US on AT&T.
I have a problem with data connectivity, and according to Samsung tech support, it is because of the Canadian firmware/baseband version.
Can I change the firmware/baseband version from Canadian build to US build?
If so, how would I do it?
Thank you for any help.
What is the ROM and baseband on your phone? Can you make phone calls?
I could be wrong, but based on my experience with the T999, that shouldn't be working. While flashing a T999V baseband won't hurt it, it simply won't work.
Please tell us your current baseband, current rom, and current firmware build. Enter this in terminal emulator to determine base firmware build,
getprop ro.bootloader
Also, can you verify by the sticker under the battery that it is an I747 and not an I747M?

Yes, I can make phone calls. I get 4G data connection, but it is slow and keeps dropping, even though it still shows 4G.
If I swap the sim to my old phone, all data connections work great, so I know it's not the sim or the network.
It is in fact an i747M

Ok! Everything looks like it should. You could try updating to the 4.4.2 build, but keep in mind you cannot go back to 4 3 afterwards. (You can flash older ROMs but not firmware). And do not flash a 4.4 2 modem on what you are running now.
You can flash the ROMs built for the i747, but for the modem you can only use the I747M.
If the store you got it from told you it was an I747, you might be able to return or exchange it due to incorrect listing.

It was sold as an i747, not i747M, so I will just return it.
The modem is what connects me to the network, so if it remains the Canadian version, changing the firmware won't solve my issue, right?
Thank you for your help!
All I can say on that is you should never flash any firmware that is for any other model device. Its just not safe to do and will almost always cause a hard brick.

So basically, if you're unable to use it as it currently is, I personally think the best option would be to return it and try to get the US I747 model. If you go in and try changing the firmware and it ends up bricking, you'd probably lose the ability to return it, so IMO its just not worth the risk.

I am going to send it back tomorrow. I don't want to have to flash anything. It should have worked right out of the box, so I'll just return it.
Strange that the Canadian version didn't work as it should. I have an HTC Desire A8182 that is a Telus version, unlocked, and it works just fine on AT&T. No data issues at all. I rooted that one as it only has 100MB internal memory, and I wanted to get rid of bloatware and use Link2SD plus to move apps to the SD card.I didn't use a custom rom, just rooted stock firmware. It's still running 2.2 FroYo, and I love it! It's only 3G, and a tad small, which is why I decided to go with the S3.
Thanks again for your help!
Seemed a little odd to me as well, but there have been a lot of upgrades and enhancements done to many US networks that may not have been done in Canada. Its just a theory, but I747 firmware may have been built to take advantage of that and the I747M might be made to work better with older or just different networks. Kinda hard to explain what I'm thinking here...
Its also possible that the US and Canadian 3g networks are more similar than their 4g ones, which might explain the different experience with your older device.
And then again, you might have simply received a device that had something wrong with it, which you'd want to return anyway I'm sure.

I sent it back today and the seller will refund me when they receive it.
I found an interesting tidbit on the AT&T forum regarding the S3.
"The international edition won't support LTE bands"
Ordered a US version (presumably, lol) today.

For no valid reasons AT&T Galaxy S3 stock ROM I747UCDLK3 has been nowhere to be found for download.
Both links from Sammobile and Samsung-updates only says "This file is either removed due to copyright claim or is deleted by the uploader"
There must be something fishy goin on right here, they don't even released the full stock of recent UCDMG2 update. This is the first time I heard somebody filed copyright infringement of those stock firmware? Why the heck it's only the UCDLK3 and not all other older stock versions like LEM and LG1. So watch out AT&T subscribers!
Its still up in the development forum if needed.
It can still be flashed from the official KIES software.

But why take down the stock firmware? I just needed it to fix auro rotation in one of my kids s3. I found it with help from an op anyway and it did the trick. I just remember 4.1.1 and earlier were simple to unlock. 4.1.2 done away with that method. 4.1.2 is still available for download also. I elieve 4.0.4 is too though, so my theory has some holes in it if it is. Whats tough is finding US stock firmware for sgh-i497. I flashed umama1 or umama2 and lost my wifi for a day. Found 1 rom finally and fixed it with 4.0.4. Need to find or make a JB rom for it after it gets repaired y Samsung. LCD went bad Gotta update N S3 to kk soon also... I never like flashing a new bootloader and knox bugs me 8n the new version.

You were right about the bootloader, but wrong with the reason. Its identical to the S4 bootloader aside from the S4 having a critical value of '1' in this code somewhere... Thing us though, that the LK3 bootloader could remain intact and signed, therefore flashed and accepted by the S4 as an update... That us IF it turns out to be truly identical lol. I got a lotta code to read over. Caffeine time.

Before doing anything else, I would recommend doing the free sim (carrier) unlock while you are still on 4.1.1. This will give you more options in the future. The method can be found in these forums.
If you were on AT&T I would say there is a chance you could take OTA updates to get to a bootloader that would work with SlimKat 9.0. I don't imagine you can do this.
Just noticed you have TWRP. Which version do you have? you will need a fairly new version to flash SlimKat 9.0 and a newer bootloader and modem, check HERE for both .tar and .img files.
You will probably be able to run slimKat from the MJB bootloader and modem (from the 4.3 rom). You could even do so with the MJ2 bootloader and modem, but you would need a custom kernel such as ktoonsez to do so. If MJB does not work well for you NE4 definitely would, it is from the 4.4.2 release.
Thank you for your response. After posting, I did a root check and found that the phone had only been partially rooted. I downloaded the apk root master. From there I had already downloaded the slimkat 7.0, I was mildly impressed, and now desperate as this is my only working device. Plus, I was terrified I was about to brick it. Anyway, I found LiquidSmooth KitKat os. 4.4.4, downloaded it plus gapps. Everything seems great! Still don't get the connectivity Metro shows for my area, but no bad. But I do have an issue with the front camera. When you take a pic, the phone reboots. The gapps came with Google camera. Tried the camera 360...exact same issue. Not that big a deal. I know have far more flexibility with my service provider in the settings.
So, thanks again for the info. I still have a SCH-720T I wanna do a sim unlock. Between Sprint,Knox and lollipop. Everything I've read says I've got my work cut out !

I have seen reports that Open Camera solves some of the camera issues on AOSP/CM roms.
I am beginning to have some problems with liquid smooth. I would still like the slimkat 9.0. I have twrp v 2.8.0.1, and recently downloaded the tar and img. I believe the modem I have is 4.1, I'm not sure as I just downloaded the liquid smooth KitKat 4.4.4. I'm still new to ALL of this. So I don't know how to get the most appropriate bootloader or kernal you mentioned. Is the slimkat 9.0 better? My connection really sucks now and so does batt life. SOS!!!!

Are you having phone connectivity issues or data connectivity issues? If it is phone connection you may need a newer modem.
Before changing modems, have you checked that your APN settings are correct? You may need to verify this with Metro.
Since you said you tried to install the MJB modem but received an error, I guess we need to try to eliminate that problem. Did you try to install only the modem or both modem and bootloader? I would recommend installing the MJB baseband (=Modem) and bootloader together. Once you get past MJB version you must keep the bootloader and baseband matched, so we may as well start that practice now. Is it possible you had a bad download of MJB? Re-downloading may solve the problem.
Do not skip MJB and go to NE4 or NJ1, both newer versions of the modem and bootloader. All I have read indicates that you should update in order without skipping or risk bricking the device.
Your version of TWRP is recent enough that it should work with the files you need. (TWRP is now up to 2.8.7.0 for the d2att.)
I have data issues. I've located 2 sources to download the modem/bootloader you mentioned. The first is out of Quebec and has a bad signature. My device also skips md5 , not sure about the issue there. And the other source has too much red tape before I can get to the down load. I have the correct network settings. But I should have excellent 4g. I don't and I believe there is a conflict with the baseband/modem and the 4.4.4 liquidsmooth os.
And thanks a ton for all the help you have given!

Frequently data issues are a matter of bad APN settings. Have you checked to see if yours are correct?
This thread by enewman17 discusses upgrading modem and bootloader starting at DLK3. He has links to bootloader and modem files. There should be no issues with signed files.

That has information that may be the key to solving your issues.
I am extrapolating from much reading about people using the MJB, android 4.3, bootloader and modem on KitKat ROMs. The ROMs I read about were TouchWiz based, but the info may still apply. (MJ2 was the leaked release of MJB. The only difference I recall is that MJ2 did not include KNOX, and you can downgrade from it.)
People were having issues running the KK roms from both the MJ2 and MJB bootloader and modem while using the kernel that came with the custom TouchWiz ROMs. Their issues were solved by changing to one of two specific kernels. ibuddler developed one of the kernels, links to it can be found in the OP of LikeWise ROM. The other kernel was by ktoonsez, I don't have a link to his thread. You can not use a kernel for a TouchWiz ROM with an AOSP based ROM. Fortunately ktoonsez also has a kernel for AOSP roms.
Full disclosure, earlier Kitkat ROMs ran fine on MJ2 and MJB, it was later builds that needed either updated firmware or the custom kernels.
I found the kt747 zip and tried v3&v4 of ibuddler. Tried to reboot and each would not boot( over 10 min). But I was able to find this ad so far(fingers crossed) it seems to work just fine. I does switch from 4g to 3 when it is at idle.
3.4.101 leankernel-aosp_kitkat-9.9-+
lk_s3aosp_kitkat-v9.9.zip
I'm still trying it out,but so far so good. I'm still having issues getting an update for twrp. Speaking of updates. Liquidsmooth updated this morning. It updated the kernel and it was way wrong for my os.
Thank you so much for your patience with me in this journey into something I had no clue of. I still would like to update my bootloader and modem to NE4. But I want to wait before I screw something up. Do some more research as I am unable to use odin.

I unlocked a Galaxy S4 SGH-I337 FROM ATT I am using Tmobile services.
My question is can I install a Stock ROM from TMobile instead of having the ATT one?
I like the Wifi Calling and Tethering option.
I can tell you... But I have a LOT of readers who want to know how to do what you have already done! How did you SIM unlock your SGH-I337? There is a published method for AT&T and TMo that seems to no longer work on the AT&T variant.
OK.. I won't hold you hostage, but I really would like to know!

Yes. But also check this thread. The AT&T boot loader is locked and may require Loki Doki patch when you are done.

.... I may be wrong here, but since when has it been OK to Odin different carrier's stock .tars? Flashable CWM zips yes, but the bone stock tar with modem, baseband, etc?
Also, being that you have TMO service and an ATT device; flashing a TMO ROM with WiFi calling should work; just use an ATT kernel and the Loki patch. Personally, I'd flash the rooted stock MDL or a custom TouchWiz via CWM or whatever recovery you happen to use and not use Odin.

Since wjenmisnit OK to do it differently?
It is only OK to do when you know what you are doing. In this case the hardware is absolutely identical. You're not going to be using AT&Ts baseband firmware on the T-Mobile network are you? Good luck with that.

So I have an unusable rooted, unlocked S4.
I've tried various APN settings to no avail... Thought I would try liquidsmooth ROM, or any ROM that works on both AT&T and T-Mobile... I assume T-Mobile /MetroPCS would react the same. And I am on a pay as you go plan that is similar to T-Mobile's s. I could easily switch to them if not...
Questions:
Has anyone any advice that could help?
Does anyone know if T-Mobile requires a "pairing" of sim card with phone's IMEI as MetroPCS does? (big pain in the butt)
I've done the same thing flashed roms, Modems, To my luck nothing, I did filing that since I repaired the imei, That is when the problem started. Also to does not tie imei to sims. Did you repair imei

Easy free Sim unlock
Just wanted to point out that if you know someone who has AT&T service they can unlock your phone for free My girlfriend did it for me on their website and it took 24 hours for them to send an email with the unlock code. Just thought i should share that. Up next getting this t-mobile rom onto my 32gb i337 at 4.4.2 with NB1. I hate everything AT&T and God is this phone bloated!

Don't they have to be the owner to request an unlock?

To be honest i can't answer your question. The phone i bought was from a guy who sold it to me out of eBay with a none working screen, he had the imei in the pics so i ran an imei blacklist check and it was clean. I asked him why he didn't fix it and said it was out of warranty so he just left it dead. I guess it was paid for but in his account so it was free for anyone to use but letting my girl do the unlock request worked so if you have a phone that's not blacklisted and you its not associated to an active account I guess it could be done. Try it, it's worth the try.
Similar question
Very first post, not sure if I should have started a new thread. Anyway, I have an ATT S4 I337 with the MF3 baseband. It's rooted, region unlocked, and fully switched to t-mobile service using a method I found on youtube, which worked fairly well except had to modify two things (I can help if you're having trouble). Now I'd like to upgrade firmware (I'm still on 4.2.2). However, I have a lot of uncertainty because of all the changes I've made. If I temporarily unroot, who am I going to get updates from? Do I need TMO or ATT custom ROMs if I want custom (have they solved that bootloader issue yet?). Basically, what's the safest way to update firmware?
Thanks in advance

Since wjenmisnit OK to do it differently?
It is only OK to do when you know what you are doing. In this case the hardware is absolutely identical. You're not going to be using AT&Ts baseband firmware on the T-Mobile network are you? Good luck with that.

The above also omits that if you are on Android 4.3.X than the bootloader on your Samsung Galaxy S4 contains a bootloader restriction preventing any downgrade which means you would be unable to flash MDL (ie. M919UVUAMDL) since MDL is Android 4.2.2.
Does anyone know a way around this bootloader restriction thereby allowing a downgrade to 4.2.2?
att i337 to t-mob stock
Hi, Im pretty new to this firmware and different model numbers etc.. but here goes. I bought a samsung s4 on att i337 a few months ago off a friend. I paid an online company for the unlock code and received the code within 24 hours. The phone is now unlocked and I have a T-mob sim in it, i'm now looking to update the firmware to t-mobile 4.4.4. Can i download a t-mob stock rom for i337?? I'm worried that this might break the phone as everything I see for t-mob is SGH-M919. Should this matter now that the phone is unlocked?? Thanks
No, you need to use ATT firmware due to hardware differences (antenna/radio). Also as I recall ATT S4s have a locked bootloader meaning only safestrap compatible ROMs can be used, unless something changed since I had one last summer. Sold it, on Swappa, and bought a TMob version with unlocked boot loader and sim unlocked!

Hi! I am having major issues with my s4 i337 after switching from att to tmobile. The phone was unlocked so I took it upon myself to unlock it. It is unlocked but sometimes or rather most of the time does not pick up the network. When it does have data connection, it is Edge. I flashed the NC1 to root my phone, then reflashed to NJ4 (to unlock) but now nothing works. No wifi, camera fails, no multitasker, no voice assistant. Please help!!!!! I don't know what to do. I should have never unrooted it to unlock. I should have paid the $35 to get an unlock code. Can I fix this?

I am not sure. I flashed NB1 as suggested by another forum member and everything is working once again. Although it went back to 4.4.2.
Now it has this notification : security notice: unauthorized actions have been detected. It wants me to reboot to revert the changes. How do I make this go away and will it go back to its unusable mode if I manually reboot?

i have samsung galaxy s7 edge att unlocked with tmobile sim card and my last 2 ota upgrade are from tmobile G935TUVU4APK1
Hey guys so I decide to get the SGH-147 AT&T S3 off of ebay for MetroPCS which enabled me to get a 2 year squaretrade warranty. After looking back at it now, I feel it might have been a bad idea since Metro has a MIR 349.99 deal for their S3 version which would mean easier android update since it would be on Metro servers if I'm not mistaken. Anyway I can't return the ebay phone now unless there is some software or hardware problems within 30 days
So my problem
I am stuck on 4.1.1 on Kies and when I check for update, because the phone is based on AT&T servers, it won't work since I'm on Metro. I wanted to see if there is anyway for me to update my phone to 4.3 which is the current version. Although, I've heard some people have 4.3 problems?
If that's not advisable, could y'all tell me how I could atleast get to Android 4.1.2? Also is there a 4.4 update in the works?
I just got the phone today and would like to be running on something better than 4.1.1
should I flash the AT&T phone to a MetroPCS ROM lol, if any of those are actually available, or if I were to flash, should I flash it to Tmobile?
First off, if its I747, you MUST flash only those Roms. No others. Now, that's indeed a nice phone with LTE Antenna.
You really heard correct. The 4.3 upgrade from the carrier (ATT for you) /Samsung has a lot of issues. I wouldn't do it for any reason. Particularly on T-Mo network, you will have severe signal issues as reported by others. In addition, it now flashes an EFuse onto your phone along with locked bootloader and other scary stuff.I really would not do it.
Lastly, XDA is organized by devices. So even though you are a T-Mo/Metro PCS customer, you will have to post on AT&T SGS3 forum over there.
Speaking of Rom update, Please visit Root66 Thread for this device. You will find Rooted version of your Current Rom. Dunno why but he does not have 4.2.x for you. Please do your research someone else must have posted it.
Now speaking to 4.3, yes there is a way to get 4.3 on your phone without the issues I mentioned above. But first you will have to flash a Custom recovery such as CWM or TWRP with the help of ODIN on your phone. Again do your research well. Once those are in place, take a look at this thread. It will provide 4.3 experience without ANY concerns or issues. Read it carefully and then read some more. Good Luck.

THANK YOU! Looks like I got a lot of phone work to do over the weekend. SO do you think it was good/should I stick with this AT&T S3 or should I try to sell it for a discount and buy a Metro PCS S3? The ebay buyer won't take my phone back unless there is a hardware or software problem inherent to phone...unless I fake one ?
If it was me, I'd keep the phone. Metro's S3 does not have LTE Antenna. You'd have been stuck at lower speeds.

Metro's s3 does have lte
As for the OP you can flash at&t or T-Mobile ROMs it really doesn't matter because they are backwards compatible (I have done it) and you can flash 4.3 ROMs if you don't want to take the official 4.3 update which you can easily do with Odin without the need for kies or ota.. Now, I suggest the first thing you do is flash a custom recovery and then experiment with 4.3 ROMs, if you keep having problems flash 4.1.2 roms.. There are some things you need to do though to get 4.3 up and running so I suggest you read up on it first. Good luck my friend!

Glad someone asked that. I looked for a few hours last night and came up empty(been working an off shift so I might have missed it). I am on 4.2.2 MDL and signal is definitely much weaker than my Active on 4.3 . Has anyone compared modems to see which are better?

I can provide anecdotal evidence but nothing real...
MK2 is better.
Also, as for which modem to flash; T-Mobile's MK2 would be the one to flash. I've read you can flash other carrier's modems as long as they are the same version, i.e. AT&T MK2 or T-Mobile MK2... but that just doesn't make sense to me and I wouldn't recommend it. The modem you flash is independent of who your carrier is; you go by what brand of phone you have. If you have the M919 then you flash T-Mobile firmwares/modems/etc regardless of which carrier your bill comes from.

I've encountered the same thing with my M919. Switching between Android 4.3 and 4.4.2 modem.bin files made no difference.
I did notice that when I changed my network preference from 3G/2G to 2G-only, I gained about 10 dBa when the handset fell back to GSM-EDGE mode. It made a big difference. I verified that AT&T only uses band II (1900MHz) for GSM and UMTS in my county, so it wasn't because I switched to band V (850MHz) which seems to have better range. What I find annoying is that the handset isn't dropping down to 2G automatically when reception is poor. It'll stick with 3G even when the signal strength is as low as -107 dBa.
No LTE at the moment since my AT&T MNVO doesn't support it.
I'm thinking of buying an M919, carrier unlocked, to use on ATT, so that I can get a proper recovery and have full access to custom ROMs without the safestrap limitations.
Is it safe to say that:
1. If I buy a T-Mobile S4, and it comes carrier unlocked, it will work fine on the ATT network, including 4G / LTE? Lots of data points suggest this but I haven't heard it explicitly stated...
2. Though I could use the phone as identified as an M919, I really want Play Store to see it as an I337 (ATT version), so I can install some ATT specific apps. Is there any problem flashing a build.prop (available in the ATT threads) with the ATT identifiers & APN info, to enable this?
3. Are there any gotchas I should be aware of? Basically, I just want a phone with unlocked bootloader / kernel so I can play. Not too worried about Knox/warranty.
Any insights would be appreciated!

Will the T-Mobile S4 work on the AT&T network; yes it will work if it's carrier unlocked. I purchased my M919 full price out of contract while I was still on AT&T service. Once I carrier-unlocked I was able to pick up AT&T's 4G/LTE and was even able to make use of the AT&T 3G Microcell device which transmits a 3G cell signal and runs over your WiFi. I now have Net10 Wireless with an AT&T SIM card and I still get 4G/LTE when it's around.
Your second question: I do believe that's all that would be required. I'm not 100% sure if just modifying the build.prop would allow you to use the AT&T-specific apps in the Play Store. I never used them to begin with so I never explored whether or not I could make them work on the T-Mobile firmware. Now, I know this involves more than just a build.prop edit, but a 100% sure way to get AT&T Apps working would be to flash a custom ROM based on AT&T firmware. Being that you have a T-Mobile device and are using it on another carrier's network, always remember; when it comes to Odin especially, flash things meant for the T-Mobile M919 ONLY. It doesn't matter that you use AT&T service, your device needs T-Mobile Modems/stock firmwares/etc.
As far as gotchas... not that I can think of. The M919 has an unlocked bootloader and even with KNOX is very easy to root and use custom ROMS on. If you're not concerned with KNOX then you really don't have to take into consideration any special rooting method, no safestrap junk, etc. Without root, just flash a recovery in Odin and flash away.
I know this thread is a bit old, but the situation is very relevant to me. I just won a S4 M919 on eBay which will be delivered tomorrow. T-mobile has agreed to send me an unlock code. My motivation is to install TWRP recovery which I can't do on the i337. I intend to activate it on Cricket (AT&T network). Is it still true that I should stick with firmware, ROMs, and modems designed for the M919? I don't care about AT&T or T-mobile apps so that's not an issue. Basically, I want the best data rates available. Any gotchas that I need to be aware of?

Basically, you're best off bringing the phone to current M919 stock through ODIN. Is that NK2 or has there been a more recent version? I've lost track. But do the entire phone, and in fact as you will see from some threads it is often necessary to flash it twice in succession to get everything to stick. This will bring you to the latest modem. Remember, the modem is two parts: the modem.bin (also known as the gsm modem, which isn't specifically dependent on the bootloader version you have) and the LTE modem (non-hlos.bin, which is dependent on the firmware version, and bad things happen if you mismatch).
Since your phone is out of warranty, there's no downside to going to the latest, even if the phone arrives with 4.2.2 firmware (pre-knox). Tripping the knox bit is only a problem if you would be sending the phone in for warranty service.
I've got the M919 and am using it on ATT, with no problems. I've got the pre-knox firmware (MDL), and will be updating to the latest next time I flash.
Here is an old, but still relevant, thread about my experiences with M919 on ATT.

Thanks a lot for that update. As I understand it, the current firmware is NB4 according to this site:
http://galaxys4root.com/galaxy-s4-stock-firmware/
Not sure what your reference to NK2 is? That doesn't seem to correspond to either 4.2.2 nor 4.4.2? I'm currently on Cricket with a S4 I337 and hope to move the SIM over as soon as my M919 arrives tomorrow.
I believe after NB4 there was NH7 then NK2. Check the firmware thread in the general section for details / links.

I use my SGH-M919 on an AT&T network also. I use the OK3 modem firmware and it seems to work great here. Although I am in Alaska, so top speeds of LTE are only about 6 Mbps where I live. Usually I can only get about 3 Mbps due to the lack of coverage around here.
You can either update to the latest OH3 firmware on your phone, or if you have an old model, with the MDL bootloader, you could also use this guide by lordodin912:

I flashed the Root66 KitKat update for Wind Mobile using Odin. As I was looking through the settings I noticed there were no APNs set. I googled for Wind's APN configuration and manually entered them (before I even tested data, perhaps it was working regardless).
So far I've seen a number of mentions warning against flashing the 4.4.2 modem before flashing the 4.4.2 firmware update. However, I've yet to see the modem posted anywhere. The most recent one in the baseband thread was for 4.3. What am I missing?
Normally 4.3 modem will be working for 4.4 too but you should not have older modem then 4.3
Sent from my SGH-T999 using Tapatalk
It hasn't been posted for that same reason, so nobody will attempt to flash.. Anyone can make a flashable zip for the modem, that it why we are letting people know what happens when you try to flash on older firmware
Sent from my SGH-M919 using Tapatalk
Ill still post the modems in the near future, but wanted to first get that warning out so as many people as possible already know about it when I do. Flashing the 4 4.2 modem on 4.3 firmware has bricked quite a few devices in the Spirit and AT&T forums already. And despite all our efforts, we have yet to get the debrick method to work
That said, if you have a need for the modem, ill get it for you as soon as I can.
And just fyi, after updating to 4.4.2, you cannot use any older modems. They won't brick the device, but you won't have a working radio/signal.

Flashing the 4 4.2 modem on 4.3 firmware has bricked quite a few devices in the Spirit and AT&T forums already. And despite all our efforts, we have yet to get the debrick method to work
That said, if you have a need for the modem, ill get it for you as soon as I can.
And just fyi, after updating to 4.4.2, you cannot use any older modems. They won't brick the device, but you won't have a working radio/signal.

Heya Doc
I have a Gs3 T999v from Videotron and have been running the 4.3 modem since early this year. I'm currently running CM11 4.4.4.
I was wondering if it would be possible to provide a link for their 4.4.2 modem so I can give it a shot. I know I won't be able to come back from it, but reception with the 4.3 has not been that hot and I've been meaning to get those kinks out. Also since the phone is nearing the end of it's life, at least to me, I don't mind the extra risk. Even if it should technically be entirely safe to do so since i'm running 4.4.2+
Cheers!
