[GUIDE] Root and Unlock Canadian i337M without tripping Knox - AT&T Samsung Galaxy S 4 General

Tested on my Canadian i337M S4 (4.4.2 MVLUFNI2 firmware). Knox was not tripped.
This may work on other S4.
Summary of the Steps:
- Downgrade to special Kernel from W0lfdroid
- Root with TowelRoot
- Flash back 4.4.2 Kernel
- Downgrade to 4.2.2 Modem
- Unlock with RegionLock Away v1.3
- Flash back 4.4.2 Modem
Detailed Steps:
-=FILES REQUIRERD=-
Download these ROMs from SamMobile:
4.2.2 rom for your phone
- Use 7zip to extract MODEM.BIN from it
4.4.2 rom for your phone
- Use 7zip to extract MODEM.BIN from it
- Also use 7zip to extract BOOT.IMG (this is the Kernel), and archive it as a tar file.
-=ROOT=-
Follow this method:
http://www.w0lfdroid.com/2014/09/To...4-S5-and-Note3-Android-4.4.2-NF-or-Later.html
Important: for flashing back the Kernel, the 4.4.2 file from that site may not work properly (causes wifi to behave weird). You need to use the boot.img tar you made earlier.
-=UNLOCK=-
1. Put S4 into download mode by holding Volume Down and Home Button on startup, then press Volume Up
2. Attach Phone using USB cable
3. Start Odin
4. under the Files [Download] section 3rd button (Phone) point to the 4.2.2 modem.bin
5. click on start
6. --- After phone reboots, check it installed correctly by verifying the baseband version is the same as the one you just flashed
7. Once successful run RegionLockAway
8. Next you must install proper modem back using Odin
9. Start Odin
10. under the Files [Download] section 3rd button (Phone) point to the 4.4.2 modem.bin
11. click on start
12. --- After phone reboots, check it installed correctly by verifying the baseband is the same as the one you just flashed

Using Heimdall on Linux to flash stock ROM and getting everything back to original tripped KNOX for me.
Everything was done properly and ROM worked perfect. Oh well.
Tip: (lol)
When flashing stock firmware back to device stick to Windows stock ROM flashing methods. (Odin)
Wish I would of found this info a few weeks ago. niCCe!

ngold thanks
I have a phone from a guy at work it is a Rogers phone KNOX is already tripped the phone is rooted and on 4.4.2 MVLUFNI2 firmware can I still use your unlock method?
And if so which 4.2.2 firmware did you use on Sammobile I don't see any Canadian firmware listed for 4.2.2.
Do you have a link to the RegionLockAway is it just the 1.3 version I'm finding for the Note 3?

Yeah you can use this method if KNOX is already tripped. (or you can just use CF-Autoroot as it saves some hassle)
To unlock, the firmware I used was VLUAMDJ . On Sammobile, you'll see it if you filter by Canada (Rogers).
For Regionlock Away 1.3, yes you can use the one posted in the Note 3 forum - http://forum.xda-developers.com/showthread.php?t=2470551

No CF-Autoroot only roots the phone. It trips the Knox, but it's easier. So if you already tripped Knox, that's the best method to root.

Thanks dude it worked I was worried because I didn't have a working sim card in it but no problems.

I can't flash the modem, bootloader locked?

download what roms? links?

If the phone has a 4.3 or newer bootloader, the phone can't be rooted without tripping knox as far as I know.

Download this full stock firmware http://www.androidfilehost.com/?fid=23134718111254196 then use Odin to flash, once done take the OTA and it should be fine. BTW, once upgrade to 4.3 your bootloader will be locked permanently meaning you can't flash custom firmware (rom/kernel/recovery), the only thing you can do is root with saferoot. can be found here http://forum.xda-developers.com/showthread.php?t=2565758

If you still want to install custom firmware then DO NOT TAKE THE 4.3 OTA UPGRADE. If you decided to flash custom rom then after flash stock MF1, you need to unlock bootloader, root, flash recovery then flash custom rom (most custom rom already rooted so you probably don't need to root). Your phone status will be CUSTOM.

Haviing only used Odin when I initially rooted my phone a year ago, I need to ask some specifics on your instructions.
1. Do I boot the phone into Download mode when flashing?
2. Do I flash it by selecting the PDA box and selecting the file there?
3. This will make my phone basically "out of the box" and back to stock recovery, correct?
Thanks in advance.

Guide to upgrade to 4.4.2 for SM-N9005

I have seen threads being spammed with people not being able to upgrade to 4.4.2 and asking for help so i thought it would be better to make a thread for that purpose.
There is no need to root the polish stock rom if you want to move on to a custom rom after you have updated the new 4.4.2 bootloader!
You Know the deal if anything goes wrong then the blame is on you not me...
In this guide the links are for the older 4.4.2 stock polish rom "N9005XXUENA6_N9005OXXENA5".
For the newest stock rom N9005XXUENB3 and newer when available click here and put N9005 in the search box and download what ever country closest to yours that is available.
ODIN 307
Download Polish stock 4.4.2 rom "Mega mirror" and flash via Odin 307 in PDA tab and remember to tick Phone Bootloader Update.
Download TWRP for 4.4.2 and flash via Odin 307 in PDA tab. I didnt like the other recovery so i use TWRP and it's much better in my opinion.
Now you should see if the phone boots up the 4.4.2 polish stock. If it does then go to step 4. If it doesnt then move to Odin 309.
Now flash you chosen custom rom via recovery. Enjoy :victory:
ODIN 309
Download Polish stock 4.4.2 rom "Mega mirror" and flash via Odin 309 in AP tab and remember to tick Phone Bootloader Update.
Download TWRP for 4.4.2 and flash via Odin 309 in AP tab.
Now you should see if the phone boots up the 4.4.2 polish stock. If it does then move to step 4. IF it doesn't then move to step 5.
Now flash you chosen custom rom via recovery. Enjoy :victory:
Download 4.4.2 bootloader and flash with Odin 309 in BL tab. This is only done if the stock 4.4.2 rom dosn't upgrade the bootloader. Let it boot so you can check if it worked. If it did boot into 4.4.2 stock then go back to step 4. Last resort if the above didnt work is to try the SamMobile way below.

Does it have to be Polish ? Can we use other ones ?
Also, do we have to tick Phone Bootloader Update ?
I didn't tick this earlier, so it kinda screwed the phone. Softbricked it and then "kinda" fixed it.
And BTW, Phone Bootloader Update in 307 is disabled, greyed out.
But I'm running into some problems. Now I need to re-flash it.

If you follow the guide it will work and if 307 didnt work for you then 309 will.
Yes just go with the polish version to be on the safe side. I have only tried the polish version so i cannot speak for the other versions. If the 309 dont work eather then download the separete bootloader i have provided and flsh it with 309 and tick the Phone Bootloader Update.
Well, this one requires to update the modem. Not really sure I want to do that.
But, should I update Bootloader via Odin ?

md5 hash please
Hi
Can you please post the md5 hash of the file N9005XXUENA6_N9005OXXENA5_XEO.zip
MEGA does not provide hashes. The file is long and, I think it is worthwhile to check it before flashing it.
Thanks for your excellent guide.
i dont have a md5 but i checked with md5 checker and the file i have on my harddisk has - 7730BABC7713DFBE5934278FD653B3F7
Hope you can use that.
MD5 correct. Thanks.

Doesn't matter if you are gonna flash a custom rom after you get the new bootloader on the phone.
So it all depends what you wanna archive.

You don't need to be rooted. And I don't think knox will be tripped since you aren't flashing anything that's been modified, only flashing unsigned/modified images via Odin trips knox. But since you are flazing a signed modem you should be fine.

Hi,
Thanks for the guide. Very helpfull. I have a few Noob questions...
1. Do I have to do a full wipe/ cleam install after updating modem, or will the OS remain intact?
2. Where can I find the latest modem for N9005?
3. Is the latest modem always the best, or should I only update if I'm currently experiencing problems with the 'old' modem
Thanks...

1. No need. Just follow the guide, nothing more..
2. Check the modem thread that's in the general section, if you can't find it there then you may have to pull it from the stock FW. Also some roms devs have the modem in their OTA/OP so may wanna check there as well.
3. New isn't always better. Update if you have issues, if something isn't broken then there is no need to fix it.

Are you Flashing the Full Firmware to update the bootloader?
Are you Flashing the Correct Firmware for your Carrier and Device?
Your Device is in Download Mode?
USB Debugging is enabled?
You Have the Samsung Drivers installed on your pc?
If the answers to the above is Yes - Try a different USB cable and Port on your pc

[GUIDE] Sim Unlock Canadian Galaxy S4 i337m 4.3 and 4.4.2

I have looked everywhere and collected information along the way. Yet I haven't found a guide that shows Canadian S4 owners how to sim unlock their phones. The phone I have is still at android 4.3 MK6 but with the KNOX fuse already tripped. So this procedure will trip the fuse but I think there is a workaround that can sim unlock without tripping the fuse.
Jelly Bean 4.3
Here's what I did to unlock the phone:
1. Downgrade the firmware to MDJ using ODIN. (This will trip the KNOX fuse. If you don't want it tripped, I have seen others who have downgraded only the modem.bin where the hidden menu still works.)
2. Boot directly into recovery (Vol UP + HOME + Power) and do a factory reset before booting into the system. If you don't do this, the system won't boot.
3. Use *#9090# to access the hidden menu, see this thread. I found that trying to sim unlock using this hidden menu method didn't work for my phone. This was also confirmed by another Canadian S4 user.
4. So I went on to root MDJ using saferoot as the next step requires root access. I think most Canadian S4 users are referred to the CF-Auto-Root.
5. Install and run RegionLockAway.
6. Reboot phone with other sim to verify lock is removed.
7. Go into hidden menu to renable PERSO SHA256.
8. Use ODIN to restore MK6.
KitKat 4.4.2
I found another Canadian user at version 4.4.2 commenting the RegionLockAway didn't work in that version so you will have to downgrade to make it work. There's a thread over on the TMobile Galaxy S4 section that mentions downgrading just the modem.bin from 4.4.2 to a lower version where the hidden menu still works. Details of how to extract the modem files directly from the firmware are shown in that thread. For Canadian i337m users, I would suggest downgrading to 4.2.2 MDJ modem.bin. Then root and run RegionLockAway to unlock the phone. Return the modem back to the current 4.4.2 when everything is done. This approach seems to work for TMobile S4 users and it doesn't trip the KNOX fuse. I have never tried this so try at your own risk.
what about the normal ATT s4?

This thread was created for the i337m Canadian S4. There's other threads that discuss methods of sim unlocking the ATT S4. Here's one of them.
I just rooted my Samsung Galaxy S4 (I337m) phone using the CF-Auto-Root method (for Canadian models only) by Chainfire. And then installed and ran the regionlockaway.
Worked like a charm. Now I have an unlocked S4. I was on Bell. Tested it on Virgin simcard, it works

Worked like a charm. Now I have an unlocked S4. I was on Bell. Tested it on Virgin simcard, it works

Bell & Virgin are the same network
So is Telus and Koodo , Rogers and Fido
Try with TELUS or Rogers SIM in your phone
I had a locked i337m from Telus that I unlocked using the regionlockaway method and it worked for me using a bell sim.

Regionlockaway doesn't work in 4.4.2. You have to downgrade to 4.2 for it to work.
k thanks

Can we use a custom ROM 4.4.2 instead, like Maple Leaf (GE)? Or we have to stick with a stock rom 4.2.2 or custom rom at 4.2.2?
Also once regionlockaway done, is the unlock will work forever with any roms at any version?
I'm pretty new with this process...
Thank you again,

As far as I know, regionlockaway works in 4.2.2 modem. You don't have to have the entire rom in that version, just the modem file. So if your rom uses the 4.2.2 modem then it should work. Once unlocked it should stick.

You just need to flash the modem.bin file with ODIN.

Run Region LockAway from your phone after it has booted up, doesn't work from CWM or Terminal as far as I know. I have the SGH-I337m Canada Fido and was using 4.2.2 MDJ modem and it is now unlocked.. Then I flashed back to 4.4.2 Stock KitKat and all is well again and unlock does stick.

Perhaps try downloading the rom again and extract the modem file. Try flash with odin 3.07.

I've been trying a lot of modems... they all fail except 4.4 ones and 1 4.2.2 (MK6) but sim unlock doesnt work on MK6.
The ODIN 3.07 error is: Secure check fail

Bricked the S6 SM-920I. I'm at wits' end.

I got the Galaxy S6 yesterday and coming from Nexus 5, I wanted to remove the existing bloatware by flashing the XtrestoLite Deodexed ROM. This one here: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/rom-xtrestolite-deodexed-mod-edition-1-3-t3119968
I'm haven't had much experience in rooting and it's my first time flashing a custom ROM. The phone was running on Android 5.1.1.
Apparently I failed. I started with CF-Root but I wasn't sure if it was done correctly. This was followed by TWRP 2.8.7.1 . Then I tried booting up the phone and the boot logo just loops. I tried to wipe the cache as well as the Delvik-cache through TWRP but it's still the same. Then I tried to flash the stock ROM that I found online but I got the error "Nand Write Start" followed by "Fail". I seem to have tried everything and now I just want to get the phone to work again. It shouldn't be so hard.
Someone help me please :crying:
Have you tried to flash the stock rom via Smart Switch software? There's an option in the top of the window where it says "More" called Emergency Recovery. When my S6 bricked nothing but that did the trick, you should give it a try.

How did you do it? I've installed the Smart Switch software but the device doesn't appear under the list in emergency software recovery, so I can't proceed.
Edit: I managed to do it through initialization. I'll update when it's done.
Edit 2: It worked! Thanks so much!

Your PC is recognizing your phone? If not maybe you shall update your drivers first. My S6 is the same model number as yours and it does appears in the Emergency Recovery list.
Another solution could be trying to flash using another version of Odin; I saw a similar problem on another forum and it was solved using Odin 3.10 to reflash the stock firmware.
Also remember that you can't downgrade your firmware once that you are on 5.1.1, no 5.02 or so allowed.

By the sounds of it you're able to boot into twrp? If so then simply boot into twrp, connect to your computer and copy a flashable rom to your phone and install it using twrp instead of odin

Since you're using the same model as mine, what are you running on your S6 right now? Are you able to root and flash a custom ROM like XtrestroLite onto Android 5.1.1?
Can you guys help me check if this post has the correct steps or is it missing anything like bootloader and root?

Actually yeah. Earlier tonight I flashed XtreStoLite over stock 5.1.1, but I must confess it wasn't as easy as I thought, mainly because I didn't followed the steps in the right way and I ended up having to root my phone through installing UniKernel, which is pre-rooted and that did the trick for me, because I got stuck in the Samsung logo right after I tried to flash with CF-AutoRoot, needless to say I obviously couldn't root with that method and had to reflash stock 5.1.1 firmware to unbrick my phone, install UniKernel, and after that I was able to enter my phone config, uncheck the reactivation block under Find My Mobile settings (which was the reason for me to get stuck at the S-logo) and then flash through Odin XtreStoLite deodexed and Xposed FW too, so I can tell you for sure that SM-G920I can run XSL like a charm.

1. So what is the correct order?
2. Did you have to manually unlock bootloader?
3. And is it a must to install uniKernel in order to root the device?
I have no idea how to proceed now.
This requires a lot more effort than I thought :fingers-crossed:
1. The correct order apparently WAS to flash 5.1.1 bootloader and modem over 5.0.2, then root, then TWRP, then flash XtreStoLite, or at least that was what I understood from Edgar's guide (as you can tell, I hurried myself too much and was to excited to flash XLS, so I didn't read properly).
Since I (and I think you did too) installed stock 5.1.1 first, there was no way to autoroot nor ping-pong root the device, that was the reason I got stuck in the Samsung logo screen after trying to autoroot, so I had to reflash stock 5.1.1 to regain access to the device settings/Find My Mobile as I explained before, after that I flashed UniKernel and that did the trick, no other steps were required to achieve root access beyond this point.
2. I didn't had to, but your carrier may have locked yours. My device is a SM-G920I (as yours) from Telcel carrier, so I can tell for sure.
3. There are several others way to root devices running over 5.0.2, but according to my personal research there aren't much options on 5.1.1 other than flash a pre-rooted kernel, but UniKernel isn't the only pre-rooted kernel, so you can choose whichever you like the most.
If I were you the first thing I'd try, as I said earlier, would be to switch to another Odin version or another firmware (as long as it is 5.1.1) and if that don't do the trick, then I'd update drivers and try via Smart Switch again.

What did you use to root? May I ask for the link? I just tried flashing CF AutoRoot and now I think it's bricked again. (RECOVERY IS NOT SEANDROID ENFORCING) I'm thinking it might be due to incompatibility because I got it from here (https://autoroot.chainfire.eu/#odin) and the Android version states 5.0.2.

Yep, that was the exact moment where mine got stuck too, as I stated before at that time I had to reflash stock firmware. The trouble is caused by CF-Autoroot, it won't work at all when you're on 5.1.1 (at least with SM-G920I) and if you try to root using this method, you'll get stuck with the message "RECOVERY IS NOT SEANDROID ENFORCING". You'll have to reflash to stock too, I'm affraid...
Flash UniKernel via Odin once you're on 5.1.1 stock again and see the magic happen. Once you have root access, gained by this kernel, you can install TWRP and flash XtreStoLite or any other rom you may want. Here is the direct link to the post: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/kernel-stockmod-kernel-t3100395
Hope you get lucky.

I just did that before you suggested it and it worked! I was so elated! I love you bro (no homo). Our situations are identical. Now I have XtrestroLite running on the S6! Thank you so much!
Simply put:
1. Update bootloader and modem
2. Install TWRP without root via Odin
3. Install UniKernel via TWRP
4. Install ROMs!
