For Canadian i337M users, how to install GE13/14

I definitely didn't want to flash OTA official update as it doesn't allow downgrades, adds Knox and slew of other disadvantages. Why not enjoy iB4STiD's lean mean ROM? i337M meant it wasn't easy and instructions, misinformation everywhere where it took me quite a bit of time to verify and consolidate. :confused:

Since I had a hard time finding complete steps, here's my attempt to help my fellow Canadians: :fingers-crossed:

If you were like me already rooted, using a 4.2 MH1 based ROM like Infamous Alpha with 4.2 baseband. (IF YOU ALREADY HAVE MK6 BASEBAND, YOU CAN START AT STEP 6. Steps 1-6 are to get proper Android 4.3 MK6 baseband so you won't experience data drops on GE roms).

This step is necessary in order for Mobile Odin to recognize your i337m model so you can flash the modem in step 3.

Check your Settings, About Device and make sure you are showing correct Model# SGH-I337M.

If not, go modify build.prop to show that (I use ES File Explorer).

ES File Explorer, click on "sdcard", then device.

Navigate to system folder, hit the menu soft key and click on Root Explorer to bring up menu, choose "Mount R/W", change /system to "RW" so you can save the build.prop after you edit.

Click on build.prop and open with ES Note Editor, change these 3 lines to show:

ro.product.model=SGH-I337M

ro.product.name=jfltecan

ro.product.device=jfltecan

Hit back key a couple of times, it will prompt to save. Then go back into Root Explorer and change /system back to "RO".

Reboot phone and check the model # again.

This step is to install Mobile Odin and install flash kernel for the I337M.

Download and install Mobile Odin from here: http://xdaforums.com/attachment.php?attachmentid=2370928&d=1383581651

then also dl these 2 files: (1) http://xdaforums.com/attachment.php?attachmentid=2053124&d=1371595808 AND (2)http://xdaforums.com/attachment.php?attachmentid=2053125&d=1371595808

extract the apk file by clicking on the first file (ES File Explorer works great for this), install the apk so Mobile Odin can flash modems on your phone.

Download canadian i337m modem from here: http://www.mediafire.com/download/basn0c726aj019u/modem[1].bin provided by a guy from this thread: http://xdaforums.com/showthread.php?t=2535801&page=12) SAVE OR RENAME FILE AS MODEM.BIN, delete the [1] from file name

Install modem by using Mobile Odin, select Modem#2 and point it at the modem.bin file you renamed earlier, click Flash Firmware. If the phone goes to green android screen, hold down power key 10 secs, you want to be in blue android screen where Mobile Odin works its magic.

Boot back into your old ROM, check the Baseband again in Settings, About Device and make sure it's MK6.

Make sure you grab the kernel for at&t (identical to canadian i337m) from OP here: http://www.androidfilehost.com/?a=show&w=files&flid=8905 m version is for mainline, u is overclocked.

Go into recovery, do your usual full wipe, then install GE13. AFTER INSTALL, make sure you flash the kernel in previous step, otherwise it will not boot.

First boot takes a while but once it does, paydirt! Go setup and enjoy this awesome ROM. :D
