I strongly recommend reading the main thread but basically Advanced Wireless Services generally refers to the 1700/2100MHz frequency band pairing in the U.S. that will be used for T-Mobile USA's 3G UMTS network

Anybody who had luck with MG1 modem?
I tried to flash the MG1 modem from the tread using mobile odin (untar the MG1.tar, flash modem.bin using modem2 option). When I rebooted the baseband under settings/about was unknown and I couldn't get any reception. What am I doing wrong?

Im kinda confused, sorry but as far as I know there no updates for t mobiles modem/radio the only one I know from tmobile id currently is M919UVUAMDL? Many said if you flash others carrier modem/radio your phone gonna be bricked.
Please tell me that I can flash all these radio/modems it would make mr love my tmobile S4 even more. :thumbup:

Try re flashing your kernel of choice... If that doesn't work you'll have to stay on the modem specific to your carrier 1337m don't have any issues flashing international modems so I don't see why it wouldn't work.

I tried to re-flash using ODIN 3.07, and I get an error saying that the C++ runtime crashed. I wonder whether the file is corrupt (I have re-downloaded MG1.tar, still same problem).... Very odd..
Somewhat, mobile odin broke my CWM recovery as well during this process. When I try to reboot into recovery to flash the kernel, the phone simply reboot after showing th small blue rebooting recovery text. So, I had to reflash the recovery through desktop odin again... Anyhow, long story short, I have reflashed google play edition 4.2.2 kernel that I was using, and still cannot get any reception (modem section still unknown) with the MG1 modem file...

I did follow the Mobile Odin instructions.
Anyhow, now even after flashing the original standalone MDL modem through desktop odin, I have no baseband.... Kind of sucks I will try to go back to fully stock with the original ODIN package and retry later on. Hope this will fix my modem...

Ok, back to square 1. Fixed the unknown baseband and I am at the original MDL.
Now, I decided to go the DESKTOP ODIN route. Extracted modem.bin, fired up ODIN 3.07, clicked phone, selected modem.bin, unchecked auto reboot, hit start and got fail!. The phone screen shows "secure check fail : mdm". Is this MG1 modem maybe not compatible with M919?

I don't this is a good idea. Flashing other carrier's modem??

4.3 clean root on SGH-I317M on Build JSS15J.I317MVLUCMK5

Ok so this is what i did to root my Telus Device SGH-I317M on Build JSS15J.I317MVLUCMK5
I started with a factory reset from backup and reset dont think this is necessary but nice to do with a clean isntall
once that was done i turned off the device and booted into download mode volume down + home + power
opened ODIN 3.09 and added the CF-Auto-Root-t0ltecan-t0ltevl-sghi317m.tar.md5 to the AP section. then clicked start. once done the device restarts back to normal and the root is applied, but during that KNOX detects it and disables it from working.
plug device into computer and ran Kies 3 and ran a firmware upgrade and initialization. took about 20 minutes.
once phone started you will notice superSU is no longer on your system.
TEST FOR THIS PART... PROBABLY not necessary but i did this and this is what happened.
run KNOX and allow it to Install. once done it will ask you to add passwords and at the end it will say it is not compatible with this device or whatever. KNOX has now terminated its warrenty or what not and will not install.
i did not have an update for superSU on Google Play but i DID have the update on Aptoide. so i updated it and ran the program.
program told me it was no longer on the device saying the libraries or whatever were not there.
so i ran Odin and ran AP again and ran it once it was done phone started and no messages and superSU worked.
because now that you factory loaded from kies for some reason it knows you attempted it the first time that now knox will not work
not quite sure how that works or if its even relevant. but when you see in the download mode it says warrenty void 1 or whatever and the knox crap its all disabled now i am guessing because i got no problems or messages once i finished it all
so step by step.
STEP 1. put in download mode and run odin 3.09 load AP and make sure Auto reboot and F. reset time are the only ones with check marks and then click START.
STEP 2 Once device reboots you will get errors and knox blocking it. this is normal. (for me it was anyway) open Kies 3 and do firmware upgrade and initialization. depending on internet connection this could take some time. you may be able to Odin the firmware but i chose kies 3
STEP 3 Once system restore from Kies is done open KNOX and install it. should fail and say not available for this device. (happened on my device)
STEP 4 either run aptoide and download the update for superSU tho you dont see it, its still there. open that will tell you to re do the root process again.
STEP 5 run odin 3.09 load AP and make sure Auto reboot and F. Reset Time are the only ones with check marks and then click start.
STEP 6 once device has started download root checker from the google play store and test. should say success.
i did at first after i root checked it with success i rebooted the device and started it up then opened superSU asked me to download binaries i pressed back by accident and then it said knox detected would you like to try and disable knox. select yes. and then success
you are rooted and no more notifications.
THESE ARE THE STEPS THAT I DID TO ROOT MY DEVICE FOR THE SPECIFIC MODEL AND BUILD so results may differ from others. so far its worked on my SGH-I317M TELUS phone running virgin mobile sim
Hope everyone else has as much success as i did.

If you just want a custom rom all you really need to do is update the bootloader or already be on 4.3 official then just boot into download mode use Odin 1.85 to flash twrp recovery wipe your data and flash the rom you want. Or just update to official use chain fire auto root and just update supersu it will disable Knox.

If you can't find a Odin modem I would update to official then re root and flash away.

Thanks but I am not that keen on getting the official rom. For one I hate using kies, it was a mess when i tried to update with my old s3, so I have not used it at all. Plus I have tons of stuff on my current phone that i would need to restore after things are done.
Also, i'd rather not having to deal with knox if i can, even though the phone is out of first yr warranty period. I have always used custom roms on my note 2 and s3 so i will leave at that for now.

I tried that method didn't work for me. I couldn't update or use superSU maybe the root I used didn't fully install but they way I wrote down to doing it on stock room works every time.

The main reason to use a custom rom is to remove all carrier related stuff on your phone. It also let's you add different mods and features you want. For example you can use the note 3 roms. Pretty much turn your phone into a note 3.

alright ill wait till tomorrow. and hopefully i find a detailed description on how to do all this. ive only ever ran the s1 because it was bricked had to run all the modem the pda and pit or whatever a long time ago so my minds gone all fresh on the rooting and flashing roms. ive only ever run stock roms. but for 4.4 i want to get it on my device because i love the group play video and the screen recording and the other few things that are awesome on the note 3
unless there is a way to get all that on the 4.3 note 2 firmware that would be awesome as well

i317m - no mobile data with CF-auto root zip file in odin
I guess I have done enough reading to be dangerous. I wish there was a comprehensive glossary for this stuff.
Anyhow - through ODIN I have flashed CF-Auto-Root-t0ltecan-t0ltevl-sghi317m - and today I have no mobile data.
Where could I find an image to go back to the original phone and start again? It is an i317m Note2 from Bell

Basically - I have no mobile data (it seems) How can I diagnose my problem. Is there something to show signal strength. Or is there a log file showing whether my modem is handshaking or what can a guy do?

Downgrade 4.3 to 4.2.2

How do I downgrade 4.3 to 4.2.2? 4.3 has alot of problems, wifi keeps dropping. I am using Rochester Institute of Technologys internet. How would I do that?
Thanks
Tmobile Galaxy s4, m919

I don't think you can due to knox.
With the newer MK2 bootloader and knox people seem to report bricks when attepting.
You might want to root, flash the older modems and see if that makes a difference.
I ran a 4.3 custom rom with 4.2 modems and bootloader without issues for the most part.

You need to go to http://SamMobile.com and download the
official stock M919 MDL firmware for your phone.
After doing that go into recovery mode and do a factory reset.
Once that's done you need to Odin flash the stock MDL firmware.
After doing that your phone will be 4.2.2 stock.
It will need to be re-rooted if you want root access and you will also need
to flash the custom cwm/twrp recovery if you want.
Good luck!

As for your root problem, try asking this in the i9500 specific forum. Our devices are sufficiently different that what works for ours won't work for yours.
As far as downgrading, you're probably out of luck like every other S4 owner in existence.

yes it downgraded the bootloader, the modem didnt take though, the bst dongle is a phone service box. and it allowed the downgrade. i was able to get the wireless back after i upgraded to the next firmware version. i dont have the s4 any more but i wanted to try it because everyone said it could not be done. and i did it. with a service box.

[Q] GPS does not work

Hello
I have SGH-M919. First, it had stock ROM, stock firmware, and it was SIM locked to T-Mobile, so I unlocked it with SRS server service (I live outside the US, so labs in my area didn't have the tools to unlock it, since it's only a US variant. Also, other methods of unlocking did not work for me, unfortunately).
In the unlocking process I had to flash custom modem file with Odin (it was required for SRS to work). After that, I flashed CWM and CM11 and everything worked fine except the GPS. It didn't work: no GPS satellites were found.
How can I resolve this issue? Thanks.

I will try there, thanks. Although I have to mention that I think that's the problem isn't with CM but the modem file/kernel/etc

If it might be the modem or kernel then you can try re flashing the modem or trying a new kernel. You'll see a lot of GPS issues being asked about in the CM threads, tho.

Can you link me to some alternative kernels / modems? I can't find any.

Just flash the stock modem since you said it was modified, unless its still needed.. However, many users have lost GPS after flashing aosp/cm.. The fix is simple. First make a nandroid backup, flash a touchwiz ROM, get a GPS lock, and then restore your nandroid.

Sorry, forgot to mention that I already tried flashing stock rom but GPS didn't work (it did work before the unlocking), so it has to be a modem problem. I couldn't find a stock modem file anywhere.
Currently I'm downloading another stock ROM, so I will be able to bring up lbstestmode which might fix my issue.
EDIT:
The new stock ROM works fine, and the GPS was able to find signal. So, I as ou suggested and recovered the Nandroid I made before through the recovery, but now I can't find GPS again. What can I do?

NB4 modem is posted in the general section

Is this a permanent fix for GPS?

I have searched for stock modem and found this.
Unfortunately, I do have a KNOX counter in download mode so it doesn't fit.
This guide links to another modem file (that works with the KNOX bootloader), but it is for MK2, and I need BN4.. What can I do?
EDIT:
The issue is FIXED! The GPS works perfectly! Ultimately, I did install the MK2 modem and although I have 4.4.2 BN4 it works just fine.
Thanks for everyone who helped me.

Good! If you experience any issues you could flash the full NB4 firmware as well

I don't think I should, I have a bootloader with Knox (it was stated that it's only good for 4.2.2 bootloaders - ones without Knox. That's why I installed the MK2.

I'm not talking about the modem, but firmware, it will flash the modem in the process and you can flash it with your bootloader.. Like I said, if you experience problems but so far you haven't seemed to

Before I flashed the correct modem files, I flashed the latest stock firmware from Sammobile which I believe contains the NB4 modem. The GPS still didn't work, only the Mk2 modem works for me

Still, the MK2 firmware just works better for me.
Also, if I can't flash the fixed NB4 firmware because the bootloader has Knox, how will it help me if I install the non-fixed version (which is included in the firmware)? I'd be stuck with the bad NB4! There's no way to install the fixed NB4 if I have bootloader with Knox, if I understand this whole thing correctly.
P.S I am not intending to argue or anything, I am just writing what happened to me. So, if someone has the same problem and he googles it he will be able to find some useful info that took me about 2 days to find (and your generous help in this thread, of course!

The firmware will flash with your bootloader.. anyway everything is working for you so there is no need to. If in the future you change your mind or have problems PM me and I will explain or help you with it

Same here
Sent from my SGH-M919 using XDA Premium 4 mobile app

I noticed that I was getting bad cellular reception in an area that should have full mobile coverage. So I flashed the 4.4.2 fixed BN4 modem and the reception is way better (from one bar to 3 or 4), and the GPS is still working.
So, the BN4 modem did flash although I have bootloader with Knox (so it isn't supposed to work according the the modem thread)
P.S. I'm quite confused. Sorry for the noob question, but what's the difference between ROM and firmware? Is the firmware just a package which includes the ROM, bootloader and modem?

Stuck in brickloop, Tried odin stock firmware, no go

Hello all!
So I bought a SGH M919 s4 off craigslist for 150 knowing that it wouldn't boot past the Samsung galaxy s4 boot screen, Thinking it would be an easy fix by flashing the stock firmware through odin. Well that's not the case, I've tried just about everything I am capable of...
1.Both odin 3.0 7 and odin 3.0 9 both flash and the device passes but on the boot screen it says booting recovery and just sticks there, It stuck on that over night so I am being patient.
2. I've tried flashing 4.3 which fails right away leading me to believe the phone was updated to 4.4.2 at some point in time.
3. It wont let me boot into stock recovery or I've even tried flashing TWRP, CWM and it pass's but still will not let me boot into those recovery's either.
4. Tried rooting the phone a couple times and that passes in odin but does nothing after that.
5. I ve tried different phone cables, I haven't tried a different computer yet.
6. The only thing I can get into on the phone is download mode and it says this on the screen
ODIN MODE
PRODUCT NAME: SGH-M919
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0X0
KNOX WARRANTYVOID: 0X1
CSB-CONFIG-LSB: 0X30
WRITE PROTECTION: enable
eMMC BURST MODE enable
I don't remember seeing those last two things on the list normally if I can recall. Any help will be greatly appreciated and possibly a donation if we can get this thing fixed. Thanks.

Repartition it with the pit file while youre installing the firmware.
Last 2 strings are normal.

Thanks for the reply, Do you know where the pit file can be found or what do I write in the pit file box?

Ok so I pulled the pit file from another T-Mobile s4 I have and flashed that with the stock firmware and that didn't work. The phone I pulled the pit file from is on 4.3 still so I'm assuming that's why it didn't work???

Na that wouldnt matter. Your pit file is for your partition layouts. Which dont ever change.
I really cant think of anything else of why you can't get into recovery or boot the phone with everything you've tried. You might just need to Jtag the device

The OP mentions that you tried flashing 4.3 and you speculated if it had been updated to 4.4.2. Just out of curiosity, have you tried flashing the stock 4.4.2 firmware?

Yes I've been to flashing 4.4.2 and it passes Odin. I think maybe you meant have I tried flashing 4.2.2? I have not tried flashing 4.2.2 firmware yet, I might try that but 4.2.2 didn't have the Knox counter did it?

No, I meant 4.4.2. It was a dumb question, but sometimes it's the simple things you overlook. Like I said, the OP only said you tried flashing MK2. You won't be able to flash anything pre-KNOX so there's no need in wasting the time downloading the MDL firmware.
An idea would be to power the phone off, boot straight to download mode, flash NB4, pull the battery when it's complete, boot straight back to download mode and re-flash NB4. I know that you have to do that sometimes for the modem to stick, perhaps you could try that with the firmware itself. Hey, worth a shot. Good luck.

I think I might have tried flashing twice in a row but I'll try it again since I haven't tried that since I've flashed the pit file. Thanks for the tip and I'll report back after the double flash.

So I flashed it, pulled the battery and flashed it again and still the same thing......:sigh: lol Time to look for another wrecked phone for spare parts

Bought a phone off cl with a cracked screen and swapped the motherboard into the phone and it works like a champ now! :thumbup:
