You should technically be able to.do it from the phone in terminal emulator. Just take the adb shell parts off the command. Do I recommend doing it this way...not really.

Perhaps if I were to use Airplane mode (to lessen chances of something using the radio) and a script that also immediately reboots?

But then what do I do if something does go wrong and CWM doesn't work?

At worst your radio wont work..you're not messing with bootloaders so it will function just fine ..just no phone part untilled you get adb/cwm /Odin working.


Edit : I just reread one of your earlier posts...adb does not work in download mode..that is a Samsung thing. If you have adb working regularly than you should be good to do just about anything.

Thanks for clearing up the adb issue there.

Odin still doesn't work and adb gives me "cannot open for write: Permission Denied" even though I'm rooted, debugging and used Root Explorer to set / as r/w.

Anyway, I went ahead and tried it from the terminal (Loving Better Terminal Emulator, BTW) and everything seems to have worked. I rebooted to ensure the phone was okay and then rebooted into recovery, and there is CWR :)

Are you typing su with phone unlocked and screen on while using adb. You need su in order to get permissions for adb.

Yeah, using Better Terminal Emulator. Didn't help.

-Edit 1-

Okay, turns out that the root I was using was the issue. It was the early one from the first attempt. I could get rooted apps working but apparently not external ones.

I flashed the "dagkernel 0.2" updated on the 7th, uninstalled Superuser's updates and then everything is working fine. I was able to re-flash CWR via adb for the first time just now :)

You guys are scaring me..I think someone is posting that they got it to work everytime I see a new post
..I have to wait till Monday to try my fix...and that's a big if my bro will let me borrow his...need that bounty so I can get me a Note! I might end up buying one from best buy to test with. I got silver status so no restocking fee and 45 day return policy.

Now, if you are still with me what you need to do first is download a logcat app from the market. I always use catlog (i think thats what its called). Go to settings and set it up to record every 10 lines.

Now you need to flash this modem onto your phone using odin http://www.4shared.com/file/GLhtc1O_/PDA_KL1_modemtar.html - after you've done that reboot, and then go and open that logcat app up and set it to record. Recording saves everything as a text document on your sdcard so you can pull it later. Very nifty.

Now just use your phone. Ppl have reported the phone freezes after flashing a tmobile modem. I'm wanting a logcat to see what's going crazy and causing this to happen. Another thing you can try for funsies is go to settings and search for mobile networks and/or enter a tmobile apn in manually. If you don't know how to do this it's ok. I really just need a logcat of wtf is going on when the modem is flashed.

Seems to be a common believe that a diff kernel is needed but I just don't buy that... I'm betting it's just the modem, MAYBE some libs/modules and possibly a few smali edits. Curse not being able to test this myself. :p

At first, it was perfect. Got the 4G signal and phone was snappy, but then when I actually tried to use data, it started hiccuping. After around a minute or so, it crashed.

I tried again, this time I tried to make a phone call. The call went through, but no sound on either end. I tried changing the volume, but the hiccups started and soon after it crashed.

I couldn't get adb or Odin working before, so I finally had to flash this kernel: Version 0.2 CWM Zip from this thread: [OVERCLOCK] [3-7-2012] dagkernel 0.2 CPU/GPU Overclock up to 1.94GHz.

Here is the last logcat (with phone call crash).

If you're interested, I did manage to flash the KJ3 radio and pull a logcat of the whole thing, all the way up to the crash. I've attached the log to the Bounty thread response here: http://xdaforums.com/showpost.php?p=23477700&postcount=96


Thanks to everyone who helped me brainstorm my issues with Odin and adb :)

guys flashing adifferent modem on our phone is different then on any devices before as explained here .Also as said in the saurom thread, many users have had issues with phone freezing when flashing the rogers modem on there att device , some experience no sound cold reboot or just extreme lag .. others as said / proven by DA_G here flashing rogers modem on the att works jsut fine , so why the mixed results ? and that is on a WORKING i717 NOTE modem . Now we can try and make modem from other device work on our i717 phone , but until we figure out why some att user can flash non att modem on there phone and others cant , a true solution is yet to be found .


FYI that logact says nothign and the other logcat i have looked at trying to solve the Rogers modem issue weretn of any help either .

I am not saying to give your hopes up but I am saying we stillhave much to learn about our own device ....

Dev Whitehawkx asked for this logcat. We already knew about the issues of flashing the different modems, but he wanted to see it anyway.

I'm one of the ones with the AT&T-only modem. Any other modem gives me strange issues, all of which are dealt with in the dev thread.

Thanks for that feedback. I'm no expert, but other than the "Is the CPU pegged" message, I could see nothing. I was going to retest with full lines instead of 10, but I wanted to see what Whitehawkz had to say first.

I'm not sure of the spirit of your message, so I'll assume you mean to say that there is little interest in porting this over.

Perhaps this is true, however there are several reasons I prefer T-Mobile over AT&T, even with their 4G LTE advantage. First and foremost, my T-Mobile account has unlimited data (with slow caps).

Directly comparing my AT&T plan to the T-Mobile plan, I find that I am paying $163 per month for something that I was previously playing $100 a month for. To me, that is a pretty big deal and I'm really concerned with getting this phone moved over.

However, even with what I know now, I would still have bought this phone, even with the AT&T handcuffs.

I'm really hoping this is a reality. I am out of contract, and would like to move over to t-mo's prepaid 4g plan- $30 for 100 min, unl texts, and unl data.(4g up to 5gb)- don't want to deal with edge speeds.

Are you running the note on t-mo?? If so, how is it dealing with the edge speeds?? I very rarely use data- I'm always under 300 mb every month- but like the cushion in case I need to tether, which is once in a blue moon. And tethering on edge does not seem doable.

EDGE on the Note is pretty slow. If you are just checking email its fine, but tethering a laptop would be frustrating. I got the Sonic tmobile hotspot to carry around for 4G data. Its fast, but it sux to have another device to lug around. Im thinking of going back to edge and crossing my fingers for this to work.

I'm on the way to buy a galaxy Note.
I have a SGH-T989 with T-mobile.

add $25 for at least 3G.
I will be happy with $50 if somebody get HSPA+ on T-mobile with galaxy note.

    SOLUTION (At least one solution that works)

    jamesd86 said:

    AND IT DOES!

    Ok. I have successfully managed to get T-mobile 4G working on an AT&T Galaxy Note with absolutely no freezing. I have been able to replicate T-mobile 4G with three different modems: (1) T-mobile SGH-T989 KID, (2) T-mobile SGH-T989 VKL1, and (3) Telus KJ3. These modems can be found in this post http://xdaforums.com/showthread.php?t=1507825. Also, there is full phone functionality.

    Here is how I achieved T-Mobile 4G on an AT&T Galaxy Note.

    PRELIMINARY NOTES

    The AT&T Note was networked unlocked
    I have been on T-Mobile for the past 3 years
    I am on the T-mobile post paid 5GB Data Android Plan (with unlimited talk and text)
    T-mobile sim was in the device while testing the solution
    The Galaxy Note was rooted, and running the latest Saurom Projekt Team Rom with the kernel that comes with that rom (DA_G's kernel I think).
    The phone functions perfectly. My family called while I was testing and there were no issues.
    Photo evidence and in follow up posts.
    Video evidence here http://www.youtube.com/watch?v=xPW3DTecmVI by zedomax.

    CAVEATS

    Signal strength on my note was less than it was on my GS II. Indoors, I struggled to get two bars of reception.
    I have yet to break 5Mbps download speeds and upload speeds are low, usually 1 Mbps or less.

    EDIT: In some locations I am getting excess of 9Mbs down and 2Mbs up.

    HOW THIS SOLUTION DIFFERS FROM OTHER ATTEMPTS

    All other attempts I have seen in both threads attempt to flash both the modem (mdm.bin) and the software that runs/communicates with the modem (amss.bin). CWM solutions were worse because those solutions also flashed two lib files (libril.so and libril-qc-qmi-1.so) that might be adding to the conflict.

    Since all of the other solutions were resulting in lags/freezes/crashes, it seemed that either mdm.bin, amss.bin, or one of the lib files must be conflicting with some other component on the device. Since it was confirmed that 4G was possible before the lags/freezes/crashes, it seemed that the modem file was compatible. The only solution left was to eliminate any conflict possibly arising from the amss.bin or the lib files. In a nutshell, the solution is to flash mdm.bin without amss.bin or the lib files.



    THE SOLUTION

    I recommend using SOLUTION 1 below. It is easy and all you have to do is download the modem you are interested in and flash through CWM. But if you are game, you can go for SOLUTION 2 which is a bit more technical and requires comfort with adb and the dd command. That solution relies on adb and dd to write the mdm.bin file directly to the mmcblk0p17 partition on the device. Before we do that you MUST (1) have a NANDdroid back up and (2) you must follow the instructions here to backup your current mdm.bin/mmcblk0p17 partition so you can restore it when you need to.

    - NANDROID and OTHER PREP

    1. Do your nandroid backup (sorry, I can't explain that here)
    2. Power off phone, remove battery, and install T-Mobile sim with a smartphone/data plan.
    3. Power on phone
    4. Make sure you have adb working on your pc with all the necessary samsung usb drivers etc. (sorry, I can't explain that here)
    5. Make sure usb debugging mode is on (Settings, Applications, Development)
    6. Make sure "Unknown sources" is on (Settings, Applications ... this may not be necessary, but it worked for me, so let's just do it.)

    - SOLUTION 1 - THE NICE AND EASY WAY


    1. Using CMW, flash your modem of choice from the following:

    - Telus Kj3 - http://www.mediafire.com/?y53w18h8xx76u7z
    - T-mobile SGH-T989 KID - http://www.mediafire.com/?o7d1z5xlox1jxkp
    - T-mobile SGH-T989 VKL1 - http://www.mediafire.com/?872a6s8mccw4dxu

    2. Reboot your phone.

    3. That's it. You should be ready to roll and can ignore all the technical stuff below. That is just there so people can build on the work.

    4. To get back to AT&T you can flash this file. http://dl.dropbox.com/u/10098708/Att_ucla1_ radio.zip


    - TWEAKS

    Since most people won't need Solution 2 (below) I'll post any updates/tweaks here.

    1. Build.prop - using this build.prop I was able to reach average downloads speeds of 9Mbps and uploads of 2-3Mbps at work where I had very strong reception. Before the this tweak I was stuck at around 4Mbps down and 1Mbps up. At home I went back to around 4MBps down, but it was consistent while up speeds remained poor (less than 1 Mbps). At least one other user has reported improvements with this build.prop. I'll ask him to post his results. You can find the file here: http://xdaforums.com/showpost.php?p=23571185&postcount=290. The file is NoT a flashable zip. You have to (1) unzip it (2) remove .test from the end of the file name so it reads build.prop and then use root explorer (from market) to place it in your /system/ folder. back up your old build.prop for safe measure. Reboot.

    - SOLUTION 2 - THE TECHNICAL WAY (or if you have trouble flashing the above)

    1. Create three folders on your internal sdcard (/sdcard) or your external sd card (/sdcard/external_sd). These folders are (1) ATT, (2) TMOBILE, and (3) TELUS. Then create two subfolders in the TMOBILE folder: (a) KID, and (b) VKL1.

    2. Backup your original mdm.bin and amss.bin partitions

    - Get adb up an running and make certain your phone is connected to your pc.
    - Run the following commands to back up your mdm.bin. You may as well back up your amss.bin as well for good measure.

    - For those using the internal storage use the following commands.

    adb shell dd if=/dev/block/mmcblk0p17 of=/sdcard/ATT/mdm.bin
    adb shell dd if=/dev/block/mmcblk0p13 of=/sdcard/ATT/amss.bin

    - For those using the external sd card use the following commands.

    adb shell dd if=/dev/block/mmcblk0p17 of=/sdcard/external_sd/ATT/mdm.bin
    adb shell dd if=/dev/block/mmcblk0p13 of=/sdcard/external_sd/ATT/amss.bin

    - Good. Now your original modem files are backed up on your internal storage or external sd card. Please don't overwrite them. Back them up somewhere else just to be safe.


    3. Now we need to download and store either one of the T-Mobile mdm.bin files or the Telus mdm.bin file.

    - Download the modem you want to test from this post http://xdaforums.com/showthread.php?t=1507825.
    - I had the best results with the T-mobile SGH-T989 KID so I'll use that for these instructions.
    - After downloading the modem, extract the mdm.bin file. Remember, this is the only file you want to mess with right now. (Maybe when we do more tweaking we can optimize the amss.bin file and the lib files as well.)

    - If you downloaded the T-mobile SGH-T989 KID, save the mdm.bin file in /sdcard/TMOBILE/KID folder (internal sd) or the /sdcard/external_sd/TMOBILE/KID (external sd card).

    - if you downloaded the T-mobile SGH-T989 VKL1, save the mdm.bin file in /sdcard/TMOBILE/VKL1 folder (internal sd) or the /sdcard/external_sd/TMOBILE/VKL1 (external sd card).

    - if you downloaded the Telus KJ3, save the mdm.bin file in /sdcard/TELUS/ folder (internal sd) or the /sdcard/external_sd/TELUS/ (external sd card).

    - Good. Now you have the mdm.bin file in a location that tells you exactly which modem you will be flashing.

    4. Now all we need to do is copy the mdm.bin to the correct partition on the Note.


    - For those using the T-mobile SGH-T989 KID modem the use the following command without the quotes.

    "adb shell dd if=/sdcard/external_sd/TMOBILE/KID/mdm.bin of=/dev/block/mmcblk0p17" (external storage)

    "adb shell dd if=/sdcard/TMOBILE/KID/mdm.bin of=/dev/block/mmcblk0p17" (internal storage)



    - For those using the T-mobile SGH-T989 VKL1 modem use the following command without the quotes.

    "adb shell dd if=/sdcard/external_sd/TMOBILE/VKL1/mdm.bin of=/dev/block/mmcblk0p17" (external storage)

    "adb shell dd if=/sdcard/TMOBILE/VKL1/mdm.bin of=/dev/block/mmcblk0p17" (internal storage)


    - For those using the Telus KJ3 modem use the following command without the quotes.

    "adb shell dd if=/sdcard/external_sd/TELUS/mdm.bin of=/dev/block/mmcblk0p17" (external storage)

    "adb shell dd if=/sdcard/TELUS/mdm.bin of=/dev/block/mmcblk0p17" (internal storage)

    5. If all of that went well, all we have to do now is reboot, let the device settle down (updating the storage takes a little while longer since we put all those modem files in there), and then force the device to use HSDPA.

    - Enter the following command without quotes

    "adb shell reboot"

    - Let the device restart
    - Let media scanning complete (really, be a little patient with it)
    - Look for the 4G icon to appear where only an edge symbol used to be.
    - If there is no 4G icon, check you reception strength. I had low reception indoors that improved when I went outdoors.
    - If after trying to get a stronger signal you still only get edge, you might need to force your phone to use HSPA only.

    6. Forcing your phone to use HSPA

    - Go to Settings
    - Go to Wireless and network
    - Scroll down and go to Mobile networks
    - Go to Network mode
    - Select HSPA only

    OR

    - Enter *#2263# on the dialpad
    - Select [2] WCDMA Band Preference
    - Select [3] WCDMA 1700

    7. Ok, that's it. Next step, reading through your posts and collecting my bounty :D.

    Enjoy the picture evidence of my T-mobile on the AT&T Galaxy Note with no lag/freeze/ or crashes.

    [MOD] Enabling Tmobile 3g/4g on the Note

    The Att Note might support 3g/4g in the same exact way the skyrocket works.

    ALL CREDIT GOES TO TOMIN!!!!!

    - NANDROID and OTHER PREP
    1. Do your nandroid backup (sorry, I can't explain that here)
    2. Power off phone, remove battery, and install T-Mobile sim with a
    smartphone/data plan.
    3. Power on phone
    4. Make sure you have adb working on your pc with all the necessary
    samsung usb drivers etc. (sorry, I can't explain that here)
    5. Make sure usb debugging mode is on (Settings, Applications,
    Development)
    6. Make sure "Unknown sources" is on (Settings, Applications ... this
    may not be necessary, but it worked for me, so let's just do it.)
    - SOLUTION 1 - THE NICE AND EASY WAY
    1. Using CMW, flash your modem of choice from the following:
    - Telus Kj3 - http://www.mediafire.com/?y53w18h8xx76u7z
    - T-mobile SGH-T989 KID - http://www.mediafire.com/?
    o7d1z5xlox1jxkp
    - T-mobile SGH-T989 VKL1 - http://www.mediafire.com/?
    872a6s8mccw4dxu
    2. Reboot your phone.
    3. That's it. You should be ready to roll and can ignore all the technical
    stuff below. That is just there so people can build on the work.
    CWM. But if you are game, you can go for SOLUTION 2 which is a bit
    more technical and requires comfort with adb and the dd command.
    That solution relies on adb and dd to write the mdm.bin file directly to
    the mmcblk0p17 partition on the device. Before we do that you MUST
    (1) have a NANDdroid back up and (2) you must follow the instructions
    here to backup your current mdm.bin/mmcblk0p17 partition so you
    can restore it when you need to.

    - T-mobile SGH-T989 KID - http://www.mediafire.com/?
    o7d1z5xlox1jxkp
    - T-mobile SGH-T989 VKL1 - http://www.mediafire.com/?
    872a6s8mccw4dxu
    2. Reboot your phone.
    3. That's it. You should be ready to roll and can ignore all the technical
    stuff below. That is just there so people can build on the work.
    - SOLUTION 2 - THE TECHNICAL WAY (or if you have trouble flashing
    the above)
    1. Create three folders on your internal sdcard (/sdcard) or your
    external sd card (/sdcard/external_sd). These folders are (1) ATT, (2)
    TMOBILE, and (3) TELUS. Then create two subfolders in the TMOBILE
    folder: (a) KID, and (b) VKL1.
    2. Backup your original mdm.bin and amss.bin partitions
    - Get adb up an running and make certain your phone is connected to
    your pc.
    - Run the following commands to back up your mdm.bin. You may as
    well back up your amss.bin as well for good measure.
    - For those using the internal storage use the following commands.
    adb shell dd if=/dev/block/mmcblk0p17 of=/sdcard/ATT/mdm.bin
    adb shell dd if=/dev/block/mmcblk0p13 of=/sdcard/ATT/amss.bin
    - For those using the external sd card use the following commands.
    adb shell dd if=/dev/block/mmcblk0p17 of=/sdcard/external_sd/
    ATT/mdm.bin
    adb shell dd if=/dev/block/mmcblk0p13 of=/sdcard/external_sd/
    ATT/amss.bin
    - Good. Now your original modem files are backed up on your internal
    storage or external sd card. Please don't overwrite them. Back them up
    somewhere else just to be safe.
    3. Now we need to download and store either one of the T-Mobile
    mdm.bin files or the Telus mdm.bin file.
    - Download the modem you want to test from this post http://
    xdaforums.com/show....php?t=1507825 .
    - I had the best results with the T-mobile SGH-T989 KID so I'll use that
    for these instructions.
    - After downloading the modem, extract the mdm.bin file. Remember,
    this is the only file you want to mess with right now. (Maybe when we
    do more tweaking we can optimize the amss.bin file and the lib files as
    well.)
    - If you downloaded the T-mobile SGH-T989 KID, save the mdm.bin
    file in /sdcard/TMOBILE/KID folder (internal sd) or the /sdcard/
    external_sd/TMOBILE/KID (external sd card).
    - if you downloaded the T-mobile SGH-T989 VKL1, save the mdm.bin
    file in /sdcard/TMOBILE/VKL1 folder (internal sd) or the /sdcard/
    external_sd/TMOBILE/VKL1 (external sd card).
    - if you downloaded the Telus KJ3, save the mdm.bin file in /sdcard/
    TELUS/ folder (internal sd) or the /sdcard/external_sd/TELUS/
    (external sd card).
    - Good. Now you have the mdm.bin file in a location that tells you
    exactly which modem you will be flashing.
    4. Now all we need to do is copy the mdm.bin to the correct partition
    on the Note.
    - For those using the T-mobile SGH-T989 KID modem the use the
    following command without the quotes.
    "adb shell dd if=/sdcard/external_sd/TMOBILE/KID/mdm.bin of=/
    dev/block/mmcblk0p17" (external storage)
    "adb shell dd if=/sdcard/TMOBILE/KID/mdm.bin of=/dev/block/
    mmcblk0p17" (internal storage)
    - For those using the T-mobile SGH-T989 VKL1 modem use the
    following command without the quotes.
    "adb shell dd if=/sdcard/external_sd/TMOBILE/VKL1/mdm.bin of=/
    dev/block/mmcblk0p17" (external storage)
    "adb shell dd if=/sdcard/TMOBILE/VKL1/mdm.bin of=/dev/block/
    mmcblk0p17" (internal storage)
    - For those using the Telus KJ3 modem use the following command
    without the quotes.
    "adb shell dd if=/sdcard/external_sd/TELUS/mdm.bin of=/dev/block/
    mmcblk0p17" (external storage)
    "adb shell dd if=/sdcard/TELUS/mdm.bin of=/dev/block/
    mmcblk0p17" (internal storage)
    5. If all of that went well, all we have to do now is reboot, let the device
    settle down (updating the storage takes a little while longer since we
    put all those modem files in there), and then force the device to use
    HSDPA.
    - Enter the following command without quotes
    "adb shell reboot"
    - Let the device restart
    - Let media scanning complete (really, be a little patient with it)
    - Look for the 4G icon to appear where only an edge symbol used to
    be.

    SOLUTION (At least one solution that works)

    Ok. I have successfully managed to get T-mobile 4G working on an AT&T Galaxy Note with absolutely no freezing. I have been able to replicate T-mobile 4G with three different modems: (1) T-mobile SGH-T989 KID, (2) T-mobile SGH-T989 VKL1, and (3) Telus KJ3. These modems can be found in this post http://xdaforums.com/showthread.php?t=1507825. Also, there is full phone functionality.

    Here is how I achieved T-Mobile 4G on an AT&T Galaxy Note.

    PRELIMINARY NOTES

    The AT&T Note was networked unlocked
    I have been on T-Mobile for the past 3 years
    I am on the T-mobile post paid 5GB Data Android Plan (with unlimited talk and text)
    T-mobile sim was in the device while testing the solution
    The Galaxy Note was rooted, and running the latest Saurom Projekt Team Rom with the kernel that comes with that rom (DA_G's kernel I think).
    The phone functions perfectly. My family called while I was testing and there were no issues.


    CAVEATS

    Signal strength on my note was less than it was on my GS II. Indoors, I struggled to get two bars of reception.
    I have yet to break 5Mbps download speeds and upload speeds are low, usually 1 Mbps or less.

    HOW THIS SOLUTION DIFFERS FROM OTHER ATTEMPTS

    All other attempts I have seen in both threads attempt to flash both the modem (mdm.bin) and the software that runs/communicates with the modem (amss.bin). CWM solutions were worse because those solutions also flashed two lib files (libril.so and libril-qc-qmi-1.so) that might be adding to the conflict.

    Since all of the other solutions were resulting in lags/freezes/crashes, it seemed that either mdm.bin, amss.bin, or one of the lib files must be conflicting with some other component on the device. Since it was confirmed that 4G was possible before the lags/freezes/crashes, it seemed that the modem file was compatible. The only solution left was to eliminate any conflict possibly arising from the amss.bin or the lib files. In a nutshell, the solution is to flash mdm.bin without amss.bin or the lib files.



    THE SOLUTION

    I recommend using SOLUTION 1 below. It is easy and all you have to do is download the modem you are interested in and flash through CWM. But if you are game, you can go for SOLUTION 2 which is a bit more technical and requires comfort with adb and the dd command. That solution relies on adb and dd to write the mdm.bin file directly to the mmcblk0p17 partition on the device. Before we do that you MUST (1) have a NANDdroid back up and (2) you must follow the instructions here to backup your current mdm.bin/mmcblk0p17 partition so you can restore it when you need to.

    4. Make sure you have adb working on your pc with all the necessary samsung usb drivers etc. (sorry, I can't explain that here)
    5. Make sure usb debugging mode is on (Settings, Applications, Development)
    6. Make sure "Unknown sources" is on (Settings, Applications ... this may not be necessary, but it worked for me, so let's just do it.)

    - SOLUTION 1 - THE NICE AND EASY WAY


    1. Using CMW, flash your modem of choice from the following:

    - For those using the T-mobile SGH-T989 VKL1 modem use the following command without the quotes.

    "adb shell dd if=/sdcard/external_sd/TMOBILE/VKL1/mdm.bin of=/dev/block/mmcblk0p17" (external storage)

    "adb shell dd if=/sdcard/TMOBILE/VKL1/mdm.bin of=/dev/block/mmcblk0p17" (internal storage)
