(The Better Your Sacrifice, The Better Your Signal!)
(Post 3)


ONLY FLASH THESE RADIOS IF YOU ARE USING A MODEL
T999, T999L, T999N or T999V DEVICE!!!!!
ONLY FLASH EACH MODEM TO THE DEVICE IT BELONGS TO!!!!

CONSIDER YOURSELF WARNED!!!!​



DISCLAIMER:
Flashing radios on your phone should not be done if you do not understand what the modem/radio is! Yes, it is a simple flash, BUT, if you do mess it up somehow, it can at best prevent you from obtaining a signal, and at worst possibly brick your device!!! IF YOU DO NOT HAVE THE INDICATED MODEL DEVICE, DO NOT FLASH!!!!! If you have a different device or are with a different carrier (such as Sprint, AT&T, etc) T-Mobile radios are NOT likely to work. It has been mentioned by just a few users that you can in fact safely flash these to other US Variants without bricking your phone, but it probably will have no connection.
IF YOURS IS AN INTERNATIONAL MODEL GALAXY S3 (I9300/I9305) YOU MAY BRICK IT IF YOU FLASH ANY OF THESE!!!
I have tested each T999 modem on my own device with no issues, however, you flash at your own risk! The others should be perfectly safe for their respective models. I have never been told of any problems with them in the past!


Individual Releases

All modems are flashable from within TWRP or CWM Recovery
They are listed beginning with the latest release at the top of each models section.

T999 Modems

These modems are ONLY compatible with the T999!

T999V Modems


These modems are ONLY compatible with the T999V!
Note about these Canadian Variants: All three carriers (Wind, Mobilicity, Videotron) phones have an identical Build and Baseband. Because of this I would say the modems are likely all the same, and so the Wind modem should work on the other two carriers and vice versa. I have no way to verify this so I will err on the side of caution and continue to offer all three. If you do use one carriers modem on any other carrier, I make no guarantees that it will work. (But please let me know of any success or failure if you do give it a shot).

Team Sonic - Modem Flasher For All {Out-Of-Date}

clark44 has ported over his Modem Flasher from the Sprint Galaxy S3 variant. This is really an awesome tool and can make flashing and testing these radios super easy! You only have one file to keep track of rather than the many individual ones below! It uses the aroma installer which allows you to pick which modem you want to install. This is great for testing to find your "best" modem! Huge thanks to clark for putting in the time and effort to port it over for us! I have considered taking over and updating it, but have not decided for sure yet as we would probably need 3 or 4 versions due to the other variants and sheer number of modems available.

Flash the tool from TWRP or CWM Recovery.

Maps & Modems!

Maps & Modems



A Public Map to track which modems work best in a given area!​


No longer do you have to ask, "Whats the best modem in my area?"
Just click the link below the title and enter your location in the Google search box to see if anyone close by has entered their results!
Don't see any posted information close by? Then please run some tests of your own and help everyone out by entering your results.


I encourage everyone to run their own tests and to please share your findings. Even if there are already 3 or 4 entries for a location, please take some time to add to the map. The more tests/results posted in an area, the more reliable the map becomes!

I suggest that everyone use the SpeedTest.net app by Ookla from the Google Play Store. If you use another method, please mention it in the map information you post.


*I got this idea from meleii of the AT&T forums. Thanks to him for the idea and allowing me to copy it for use here! If you see him, Thank Him!
*Thanks to vnguyen972 for getting the map set up for us so quickly. Thank him too!


INSTRUCTIONS

Make sure you are logged into your Google account
Click the link below the title, or click HERE to open the map.
Enter your City, State and Zip in the search box. (I recommend also entering a nearby intersection to produce more accurate results)
Click on the Map Marker
Click Save to Map
Select TMobile GS3 Modem in the drop down box and click Save
Now click on your location in the panel on the left.
Please use your City, State and Zip for the title.
Enter your information into the description, then Save!


Should look something like this:

DocHoliday77
UVLI6
XquiziT v70, UVALH2, Stock Kernel (ROM, Build, Kernel)
Ping: 146-733
8-13 / 1-3 (Down / Up)


If you care to go a step further, the following would also be helpful:
Any related build.prop tweaks (More information to come later)
Any other info you feel is relavent

Of course, everything is optional. You don't HAVE to use the above format, but I think if everyone does, it will make it much easier to read.

Remember, the more data we collect, the more reliable it becomes! You are, of course, more than welcome to enter test results for more than one area. (Home, Work, Wherever you want!)
Sometimes when you search for just your City, State and ZipCode, the map marker can still be a number of miles away from where you are. If you also enter a nearby intersection you can get the Marker closer to you. I don't recommend having it point at your house!

NOTE:
If you want to help or encourage people to find and take part in this project, Please link them to this page/post rather than posting links directly to the map all over the place. This should help keep all related questions and comments here, and help prevent a bunch of extra threads which will needlessly clutter up the forums!

Thanks in advance to all who choose to participate!!!

Data Speeds! build.prop Tweaks and More!

Tips and Tweaks

In this post you will find tweaks, edits and anything else which may have an affect on your data speed.
This being the Baseband/Modem/Radio thread, I only plan to include those tips which are related to your data connection.

In the future I may start a new thread with lots more information on everything else!


build.prop tweaks​

In this section you will find different entries which can be changed or added/removed to your build.prop, located at /system/build.prop. I will do my best to define and describe what each entry does and the available values you have to choose from.

First a little general info about the build.prop file.
  • During boot, the system reads the build.prop from top to bottom. This means that if you have duplicate entries, the last one read will be the one applied. In this case you may feel free to delete any duplicates to clean it up a little.
  • You must leave a blank line at the very end of the file. Otherwise it will not be read.
  • When experimenting with different values, it can be handy to comment out the original and leave it there as a backup and reference. To comment out an entry, simply put # at the beginning of the line. Anything on that line after the # will not be read by the system. This is a good way to leave a quick note for yourself if needed.
  • If you see an entry here, but it is not in your build.prop, you can just add it in. If it is already in your file, just edit the value.

IMPORTANT!!! Make a copy of your original before you edit anything!!! Stop Here and put a copy of your build.prop on your EXTERNAL sdcard!

There are certain lines in this file which, if incorrectly edited, can cause your system to not boot. Don't Panic! Got your Towel?? Good! All you have to do is copy your backed up original back to /system/
How? Easy! Just reboot into recovery (I am assuming that if you are editing your build.prop you also have TWRP or CWM installed). Once in recovery mount your system partition if it is not already done. Now, using the built-in file browser, rename your edited build.prop and copy the original back to /system/
Reboot! (I know for a fact that the file browser is built into TWRP. I am assuming it is the same with CWM. If it is not, let me know and I will post another easy solution for you.)


==================================================================================================================


OK, I think we have covered the important pre-edit stuff!
I will start with just a few to get this going, and I will try to continue building on it until I run out of information.
I will be adding more to the list soon! (I will also probably play with the format a bit to try making all of this easier to read)

And Now......The build.prop tweaks!

Default
ro.ril.hsxpa=1
ro.ril.gprsclass=10

Usually recommended
ro.ril.hsxpa=3
ro.ril.gprsclass=12

The radio in our phone has the following capabilities:
  • HSDPA Category 24 (42.2 Mbps)
  • HSUPA Category 8 (11Mbps)
  • GPRS Class 12 (?) (4 Downlink Timeslots, 4 Uplink Timeslots, with 5 Timeslots simultaneously active) (It may be capable of a higher class, but I am not sure at this time)
  • 64QAM (wave modulation)

T-Mobile's networks support the following:
  • HSPA+42 supports HSDPA Cat 24, and HSUPA Cat 6
  • HSPA+21 supports HSDPA Cat 14, and HSUPA Cat 6
  • HSPA+ (will verify later) (believe D=10, U=5)
  • HSPA (will verify later) (believe D=8, U=5)

The ro.ril.xxxx properties are used to define the target network.
So if you are in an area that has HSPA+42, you should try these values:
ro.ril.hsxpa=3
ro.ril.hsdpa=24
ro.ril.hsupa=6


For areas with HSPA+21, try these:
ro.ril.hsxpa=3
ro.ril.hsdpa=14
ro.ril.hsupa=6


Check the HSPA+42 Fact Sheet to see if your area has been upgraded yet!


ro.ril.hsxpa defines the target networks available technology. (I have not found anywhere to verify for sure, so this is from others definitions and my own reading)
0 = 3gpp Release UMTS r99
1 = HSDPA
2 = HSDPA/HSUPA
3 = DC-HSPA (HSPA+)
4 = ?? (Maybe LTE related, or HSPA+42?, testing needed)
5 = ?? (May not even be defined yet, but likely related to LTE)


ro.ril.gprsclass defines the GPRS MultiSlot Class to be used on the target network.
10 = Slower Uplink, ?Uses Less Battery?
12 = Faster Uplink, ?Uses More Battery?

If we can verify that my theory for these is correct, I will post the HSPA+, and HSPA values as well. But you should be able to figure those out on your own.


---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------


ALL AVAILABLE VALUES

ro.ril.hsxpa=0-3
(I have seen 4 and 5 used, but cannot confirm they are really defined values, likely LTE related if they are)


ro.ril.gprsclass=1-12 and 30-34
(I have seen and used ones in between in the past, but they are no longer listed)
CLICK HERE FOR MORE INFO


ro.ril.hsupa=1-9
(10-12 may be defined at this point, but I could not verify this)
CLICK HERE FOR MORE INFO


ro.ril.hsdpa=1-16 and 19-36
CLICK HERE FOR MORE INFO


ro.ril.enable.dtm=0,1
DTM = Dual Transfer Mode -- EDGE ONLY --This defines whether or not the target network supports simultaneous transfer of both voice and data. Likely not needed at all.

ro.ril.hep=0,1
(??? I have seen this used in many places, but have never been able to verify its use) Likely not needed.

ro.ril.enable.a51=0,1 Weak, hackable encryption used to provide privacy for voice communications. Not needed.
ro.ril.enable.a53=0,1 Weak, hackable encryption used to provide privacy for voice communications. Not needed.
***These both are weak and have been easily hacked. I would imagine it would serve only to slow things down a little. Of course, there is the argument that some is better than none! I leave it up to you to decide for yourselves.​


As far as I can tell, the ONLY real tweaks you need to make for now are HSXPA, HSDPA, HSUPA, GPRSCLASS. I am aware there are others that can be added as well, but I have not done the research or testing yet and would like to nail these down first! Any help/feedback is appreciated!


***************************************************************************************************************************************************************************************


Speedtest.net Alternatives

I personally do not find the SpeedTest.net app to be very reliable or indicative of real world speeds. You can choose different servers and get wildly different results. However, as with most benchmarks, so long as you are being consistent with your use, the data can still prove useful. This is why I still recommend using only that app for posting your results to the Map.
Your results can be heavily impacted by traffic, server choice, distance, routing, etc. I have had terrible speedtest results, only to turn around and download a large file super quick! So remember, no matter what you use, these tests will not give you a very accurate reading into what you can expect with real-world use.

Below you will find listed some alternative websites where you can test the speed of your connection. I am listing them here so that you can possibly find a better testing alternative to use for your own results. If you use any of these or know of others, please share your experience and maybe we can find something better and more consistent for everyone to use!

Hey guys, I saw something pretty cool on the AT&T forums.
In their modem thread by meleii he has set up a public map in google maps where their users can enter their location and enter information about which is the best performing modem in their area.

I have seen a lot of people asking what modem is best where they are, and this may be a good way to figure all of that out. Provided enough of you would be willing to perform honest testing and enter your results on the map that is.

Ive never used public maps, but am willing to learn and implement if this is something you guys would like to see.
(As if I dont already know the answer to that!) Anyway, if you have any feedback or pointers or anything else to add please feel free to do so!

Well since we don't have a map. Who lives in Pennsylvania or Philadelphia and which radio works best?

I live in Bucks county- still testing the newest ones out. I will report back in a few days. The modem flasher is awesome as it allows you to quickly change without too much of a hassle. SO far the latest leak (UVLI5) is the best for me followed by UVLG1. I am still running some tests on the latest leak though.

Nice idea.

I created a map here... now if we all could join and contribute :)
https://maps.google.com/maps/ms?ie=UTF&msa=0&msid=206376864302453711738.0004c96ebcfb8b7b4df9b

Instruction copied from the ATT thread:
Please click the above URL and follow these steps to add yourself to the map:

Use the search box to locate your city, state, and country.
On the marker that appears, you’ll see a link that says*’Save to My*Maps‘*within the bubble.
Click the link and select the*TMobile S3 Modem.
Put your name as the title for the marker, and within the bubble provide whatever info you’d like

1. Click the map link.. https://maps.google.com/maps/ms?ie=UTF&msa=0&msid=206376864302453711738.0004c96ebcfb8b7b4df9b
...map will load
2. In Google search box... search for your location.
3. Once the marker of your location appears... click it and a small popup from the marker will allow you to click add to my maps and select the Tmobile GS3 Modem then click OK
4. Once it's added to the map... you can click on your location on the left panel to add in the Title and any description you like then click Save.

I was confused when reading the instructions on the other thread too myself :)

I still cannot figure out how to add my location to google maps. I read the post above me and I still do not understand where the "map link" is. I was able to install the modem flasher and I got the latest modem flashed without any problems. Im just confused about the google maps part of it. Any help would be sweet..thanks

    Welcome To The T-Mobile Galaxy SIII Modem Store!


    Latest Additions
    T999 UVUEOH1 and T999L/T999N UVUBOH1 modems.




    MAPS AND MODEMS!!!
    Please proceed to the back of the store to participate in this project!

    NEW Feature! Data Speed Tweaks and Info!!!
    Please proceed to the FAR back and downstairs to make an offering to our god of radio waves!
    (The Better Your Sacrifice, The Better Your Signal!)
    (Post 3)


    ONLY FLASH THESE RADIOS IF YOU ARE USING A MODEL
    T999, T999L, T999N or T999V DEVICE!!!!!
    ONLY FLASH EACH MODEM TO THE DEVICE IT BELONGS TO!!!!

    CONSIDER YOURSELF WARNED!!!!​



    DISCLAIMER:
    Flashing radios on your phone should not be done if you do not understand what the modem/radio is! Yes, it is a simple flash, BUT, if you do mess it up somehow, it can at best prevent you from obtaining a signal, and at worst possibly brick your device!!! IF YOU DO NOT HAVE THE INDICATED MODEL DEVICE, DO NOT FLASH!!!!! If you have a different device or are with a different carrier (such as Sprint, AT&T, etc) T-Mobile radios are NOT likely to work. It has been mentioned by just a few users that you can in fact safely flash these to other US Variants without bricking your phone, but it probably will have no connection.
    IF YOURS IS AN INTERNATIONAL MODEL GALAXY S3 (I9300/I9305) YOU MAY BRICK IT IF YOU FLASH ANY OF THESE!!!
    I have tested each T999 modem on my own device with no issues, however, you flash at your own risk! The others should be perfectly safe for their respective models. I have never been told of any problems with them in the past!


    Individual Releases

    All modems are flashable from within TWRP or CWM Recovery
    They are listed beginning with the latest release at the top of each models section.

    T999 Modems

    These modems are ONLY compatible with the T999!

    T999V Modems


    These modems are ONLY compatible with the T999V!
    Note about these Canadian Variants: All three carriers (Wind, Mobilicity, Videotron) phones have an identical Build and Baseband. Because of this I would say the modems are likely all the same, and so the Wind modem should work on the other two carriers and vice versa. I have no way to verify this so I will err on the side of caution and continue to offer all three. If you do use one carriers modem on any other carrier, I make no guarantees that it will work. (But please let me know of any success or failure if you do give it a shot).

    Team Sonic - Modem Flasher For All {Out-Of-Date}

    clark44 has ported over his Modem Flasher from the Sprint Galaxy S3 variant. This is really an awesome tool and can make flashing and testing these radios super easy! You only have one file to keep track of rather than the many individual ones below! It uses the aroma installer which allows you to pick which modem you want to install. This is great for testing to find your "best" modem! Huge thanks to clark for putting in the time and effort to port it over for us! I have considered taking over and updating it, but have not decided for sure yet as we would probably need 3 or 4 versions due to the other variants and sheer number of modems available.

    Flash the tool from TWRP or CWM Recovery.

    Data Speeds! build.prop Tweaks and More!

    Tips and Tweaks

    In this post you will find tweaks, edits and anything else which may have an affect on your data speed.
    This being the Baseband/Modem/Radio thread, I only plan to include those tips which are related to your data connection.

    In the future I may start a new thread with lots more information on everything else!


    build.prop tweaks​

    In this section you will find different entries which can be changed or added/removed to your build.prop, located at /system/build.prop. I will do my best to define and describe what each entry does and the available values you have to choose from.

    First a little general info about the build.prop file.
    • During boot, the system reads the build.prop from top to bottom. This means that if you have duplicate entries, the last one read will be the one applied. In this case you may feel free to delete any duplicates to clean it up a little.
    • You must leave a blank line at the very end of the file. Otherwise it will not be read.
    • When experimenting with different values, it can be handy to comment out the original and leave it there as a backup and reference. To comment out an entry, simply put # at the beginning of the line. Anything on that line after the # will not be read by the system. This is a good way to leave a quick note for yourself if needed.
    • If you see an entry here, but it is not in your build.prop, you can just add it in. If it is already in your file, just edit the value.

    IMPORTANT!!! Make a copy of your original before you edit anything!!! Stop Here and put a copy of your build.prop on your EXTERNAL sdcard!

    There are certain lines in this file which, if incorrectly edited, can cause your system to not boot. Don't Panic! Got your Towel?? Good! All you have to do is copy your backed up original back to /system/
    How? Easy! Just reboot into recovery (I am assuming that if you are editing your build.prop you also have TWRP or CWM installed). Once in recovery mount your system partition if it is not already done. Now, using the built-in file browser, rename your edited build.prop and copy the original back to /system/
    Reboot! (I know for a fact that the file browser is built into TWRP. I am assuming it is the same with CWM. If it is not, let me know and I will post another easy solution for you.)


    ==================================================================================================================


    OK, I think we have covered the important pre-edit stuff!
    I will start with just a few to get this going, and I will try to continue building on it until I run out of information.
    I will be adding more to the list soon! (I will also probably play with the format a bit to try making all of this easier to read)

    And Now......The build.prop tweaks!

    Default
    ro.ril.hsxpa=1
    ro.ril.gprsclass=10

    Usually recommended
    ro.ril.hsxpa=3
    ro.ril.gprsclass=12

    The radio in our phone has the following capabilities:
    • HSDPA Category 24 (42.2 Mbps)
    • HSUPA Category 8 (11Mbps)
    • GPRS Class 12 (?) (4 Downlink Timeslots, 4 Uplink Timeslots, with 5 Timeslots simultaneously active) (It may be capable of a higher class, but I am not sure at this time)
    • 64QAM (wave modulation)

    T-Mobile's networks support the following:
    • HSPA+42 supports HSDPA Cat 24, and HSUPA Cat 6
    • HSPA+21 supports HSDPA Cat 14, and HSUPA Cat 6
    • HSPA+ (will verify later) (believe D=10, U=5)
    • HSPA (will verify later) (believe D=8, U=5)

    The ro.ril.xxxx properties are used to define the target network.
    So if you are in an area that has HSPA+42, you should try these values:
    ro.ril.hsxpa=3
    ro.ril.hsdpa=24
    ro.ril.hsupa=6


    For areas with HSPA+21, try these:
    ro.ril.hsxpa=3
    ro.ril.hsdpa=14
    ro.ril.hsupa=6


    Check the HSPA+42 Fact Sheet to see if your area has been upgraded yet!


    ro.ril.hsxpa defines the target networks available technology. (I have not found anywhere to verify for sure, so this is from others definitions and my own reading)
    0 = 3gpp Release UMTS r99
    1 = HSDPA
    2 = HSDPA/HSUPA
    3 = DC-HSPA (HSPA+)
    4 = ?? (Maybe LTE related, or HSPA+42?, testing needed)
    5 = ?? (May not even be defined yet, but likely related to LTE)


    ro.ril.gprsclass defines the GPRS MultiSlot Class to be used on the target network.
    10 = Slower Uplink, ?Uses Less Battery?
    12 = Faster Uplink, ?Uses More Battery?

    If we can verify that my theory for these is correct, I will post the HSPA+, and HSPA values as well. But you should be able to figure those out on your own.


    ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------


    ALL AVAILABLE VALUES

    ro.ril.hsxpa=0-3
    (I have seen 4 and 5 used, but cannot confirm they are really defined values, likely LTE related if they are)


    ro.ril.gprsclass=1-12 and 30-34
    (I have seen and used ones in between in the past, but they are no longer listed)
    CLICK HERE FOR MORE INFO


    ro.ril.hsupa=1-9
    (10-12 may be defined at this point, but I could not verify this)
    CLICK HERE FOR MORE INFO


    ro.ril.hsdpa=1-16 and 19-36
    CLICK HERE FOR MORE INFO


    ro.ril.enable.dtm=0,1
    DTM = Dual Transfer Mode -- EDGE ONLY --This defines whether or not the target network supports simultaneous transfer of both voice and data. Likely not needed at all.

    ro.ril.hep=0,1
    (??? I have seen this used in many places, but have never been able to verify its use) Likely not needed.

    ro.ril.enable.a51=0,1 Weak, hackable encryption used to provide privacy for voice communications. Not needed.
    ro.ril.enable.a53=0,1 Weak, hackable encryption used to provide privacy for voice communications. Not needed.
    ***These both are weak and have been easily hacked. I would imagine it would serve only to slow things down a little. Of course, there is the argument that some is better than none! I leave it up to you to decide for yourselves.​


    As far as I can tell, the ONLY real tweaks you need to make for now are HSXPA, HSDPA, HSUPA, GPRSCLASS. I am aware there are others that can be added as well, but I have not done the research or testing yet and would like to nail these down first! Any help/feedback is appreciated!

    Speedtest.net Alternatives

    I personally do not find the SpeedTest.net app to be very reliable or indicative of real world speeds. You can choose different servers and get wildly different results. However, as with most benchmarks, so long as you are being consistent with your use, the data can still prove useful. This is why I still recommend using only that app for posting your results to the Map.
    Your results can be heavily impacted by traffic, server choice, distance, routing, etc. I have had terrible speedtest results, only to turn around and download a large file super quick! So remember, no matter what you use, these tests will not give you a very accurate reading into what you can expect with real-world use.

    Below you will find listed some alternative websites where you can test the speed of your connection. I am listing them here so that you can possibly find a better testing alternative to use for your own results. If you use any of these or know of others, please share your experience and maybe we can find something better and more consistent for everyone to use!

    Maps & Modems!

    Maps & Modems



    A Public Map to track which modems work best in a given area!​


    No longer do you have to ask, "Whats the best modem in my area?"
    Just click the link below the title and enter your location in the Google search box to see if anyone close by has entered their results!
    Don't see any posted information close by? Then please run some tests of your own and help everyone out by entering your results.


    I encourage everyone to run their own tests and to please share your findings. Even if there are already 3 or 4 entries for a location, please take some time to add to the map. The more tests/results posted in an area, the more reliable the map becomes!

    I suggest that everyone use the SpeedTest.net app by Ookla from the Google Play Store. If you use another method, please mention it in the map information you post.


    *I got this idea from meleii of the AT&T forums. Thanks to him for the idea and allowing me to copy it for use here! If you see him, Thank Him!
    *Thanks to vnguyen972 for getting the map set up for us so quickly. Thank him too!


    INSTRUCTIONS

    Make sure you are logged into your Google account
    Click the link below the title, or click HERE to open the map.
    Enter your City, State and Zip in the search box. (I recommend also entering a nearby intersection to produce more accurate results)
    Click on the Map Marker
    Click Save to Map
    Select TMobile GS3 Modem in the drop down box and click Save
    Now click on your location in the panel on the left.
    Please use your City, State and Zip for the title.
    Enter your information into the description, then Save!


    Should look something like this:

    DocHoliday77
    UVLI6
    XquiziT v70, UVALH2, Stock Kernel (ROM, Build, Kernel)
    Ping: 146-733
    8-13 / 1-3 (Down / Up)


    If you care to go a step further, the following would also be helpful:
    Any related build.prop tweaks (More information to come later)
    Any other info you feel is relavent

    Of course, everything is optional. You don't HAVE to use the above format, but I think if everyone does, it will make it much easier to read.

    Remember, the more data we collect, the more reliable it becomes! You are, of course, more than welcome to enter test results for more than one area. (Home, Work, Wherever you want!)
    Sometimes when you search for just your City, State and ZipCode, the map marker can still be a number of miles away from where you are. If you also enter a nearby intersection you can get the Marker closer to you. I don't recommend having it point at your house!

    NOTE:
    If you want to help or encourage people to find and take part in this project, Please link them to this page/post rather than posting links directly to the map all over the place. This should help keep all related questions and comments here, and help prevent a bunch of extra threads which will needlessly clutter up the forums!

    Thanks in advance to all who choose to participate!!!

    So Sorry to Everyone!

    Hey guys!

    I am so sorry for just disappearing like I did. I don't have a lot of time at the moment, so I won't get into any deep explanation right now. I just wanted to drop in real quick to let folks know I will try to get my threads updated within the next week. (hopefully this weekend). I do have an awful lot going on right now, so I may not be online to the extent that I was previously, but hopefully that will just be a temporary situation. I have a new computer and will do my best to keep up and help out like I did before.
    I offer my deepest apologies to everyone for abandoning for so long, and to those who have been concerned about what happened to me, I am very sorry for not getting in touch sooner. (No, I didn't die, get arrested, or go to rehab!) Nothing quite so bad as that. More of a "Murphy exerting dominance over life" type of thing!
    Anyhow, I have to go for now, but I am back and will talk to you guys more soon!

    :cowboy:Doc:cowboy:

    I hope everyone has been doing well!

    SGH-T999 ONLY:
    Latest UVUENC2 Modem: Modem Only
    Feel free to repackage to your liking if you decide to add it to the OP and whatnot, Doc.
    I don't pay much attention to vendor stuff, but the discussion here urged me to go ahead and pick apart the firmware (just in case the modem itself had been updated to address issues in the mentioned blog post).
    I've also made a firmware package (based on @mnasledov 's MD5 zip).[flash back to older firmware at your discretion]
    UVUENC2 firmware
    (If you're not on 4.3 firmware yet, save yourself. If you're already on Knox fw go for it)


    What are these firmware files?
    • rpm.mbn - Resources and Power Manager
    • sbl2.mbn - Part of Secondary Bootloader
    • sbl3.mbn - Part of Secondary Bootloader
    • aboot.mbn - AP Bootloader
    • tz.mbn - Trust Zone
    • NON-HLOS.bin - Modem / Radio

    Instructions:
    (1) Put this .zip file on the root of your sdcard.
    (2) Reboot to recovery
    (3) Choose .zip file from sdcard and select this file and flash it.
    (4) Reboot and you're done. I didn't find any wiping of any kind necessary.
