[I337M] MG1 Firmware Update Methods

The new MG1 firmware updates the modem, provides stability, adds apps2sd, removes smearing and other goodies. Here are a few methods to obtaining the latest update if you are rooted.
I take no responsibility if anything adverse happens to your device. Be sure to thank the OP's of the corresponding threads!
1) Download the new firmware .tar file and flash it from ODIN and re-root, or flash with Mobile ODIN and use everRoot option. You will still need to install a custom recovery again either way. Firmware can be found here: http://forum.xda-developers.com/showthread.php?t=2269304
2) Resort to stock ROM, remove root and see if device status shows "official" and try the "check for updates" under about phone to try for the OTA. Having a custom recovery may prevent this from working.
3) Try these methods for getting back to device status "official" to attempt the OTA: http://forum.xda-developers.com/showthread.php?t=2296014
Again having a custom recovery may prevent any of those methods from working.
4) If all you want is the new MG1 modem/radio see here: http://forum.xda-developers.com/showthread.php?p=43899220
5) If all you want is the ROM here is the latest MG1 firmware as a flashable zip via custom recovery. This does not include the modem however. http://forum.xda-developers.com/showthread.php?t=2375180
NOTE: MG1 removes root. Motochopper Exploit does not seem to root MG1 as of now so use CF-AutoRoot which is confirmed working: http://forum.xda-developers.com/showthread.php?t=2293800

Probably not, if your device status in about menu says "custom" instead of "official". You have a few options:
1) Download the new firmware .tar file and flash it from ODIN and re-root, or flash with Mobile ODIN and use everRoot option. You will still need to install a custom recovery again after either way. Firmware can be found here: http://forum.xda-developers.com/showthread.php?t=2269304

Again having a custom recovery may prevent any of those methods from working.
4) If all you want is the new modem from the latest MG1 firmware then sit tight as someone is trying to extract just that as a flashable .tar as of this post.

Thanks! I tried step 3 (didn't work, probably cause of custom recovery like you said). In the process of DLing the new tar file (step 1). Do I have to clean install (wipe everything) when I update using the .tar file on mobile ODIN? I have a nandroid and tibu backups just in case.

You do not have to wipe anything, however the process of flashing the stock firmware .tar will remove your custom recovery and restore the stock recovery. You will also loose root unless you use the everRoot option.
You can always re-root using CF-AutoRoot if you use ODIN or if the everRoot option of Mobile Odin doesn't work. Check here for CF-AutoRoot:
http://forum.xda-developers.com/showthread.php?t=2293800
After you have root you can then restore your Titanium Backup
Lastly you will have to re-install your custom recovery.
NOTE: In your case you are looking for the Rogers latest stock ROM you could just flash this ROM from Ib4STID directly from custom recovery, however it does not contain the updated modem. Find that ROM here:

The modem will probably help with lte speeds and reception, so I'll stick to the .tar on the official firmwares page!

I have a rogers I337M running Omega v9 (an i9505 rom based on MGA) with Adam Kernel 1.5 (an i9505 custom kernel also MGA). My phone still has the original MDJ modem/baseband. I would like a flashable MG1 modem, recovery based zip or mobile/odin flashable or whatever.

Glad to hear it! Now let's hope this new modem provides better signal and faster LTE speeds. :good:

I would like to know if anyone thinks there will be a problem if I do the following:
1) Use ODIN to flash the new MG1 firmware (rom/kernel/modem)
2) Use ODIN to flash custom recovery (TWRP)
3) Use TWRP to restore my backup including custom rom/kernel
I would just wait for the modem but I am impatient....

That will be fine. I just get TWRP from Play store via GooManager but flashing is fine too.

Did you flash CF-Root right after the MG1 flash? or did you Flash MG1 reboot the phone and then flash CF-Root?

I prefer to use Mobile Odin Pro, which allows you to inject root during the flash. That's what I did with this firmware.
If you use ODIN on PC I would personally let it reboot, set up the phone as usual and then follow CF-AutoRoot procedure.

for some reason mobile odin pro never worked on this canadian phone for me properly. notified chainfire but without response or fix.
always fails to flash csc propperly. worked wonders in the past on other galaxies and probably still does for international but now i just avoid it because of this.
can you check with root explorer whether you even have csc propper folder after using mobile odin on canadian model?

Warning!!!
Locked boot-loader, once you flash this update you cant downgrade (at Present)
Rom has no knox counter ( warranty Bit) or binary counter.
Rom used to downgrades was T310XXUAMF1_T310OXXAMF1_HOME.tar
Another safe way of trying this rom without fear, is flashing it with mobile odin,mobile odin does not flash boot-loaders so you are safe to downgrade etc.
you may find that you WiFi does not work when rom flashed with mobile odin, that means that the older boot loader is not compatible with the new rom.
Update 1
Once You flash the rom the device will reboot several times, because my previous rom was customized i had to perform a hard reset.
this rom has some kind of KNOX according to superuser
The rom also adds a new entry to download mode AP SWREV: A1
How to root?
download Cf-auto-root from here and flash it via odin then go to google play and install superuser from chainfire, launch it and update normally.
UPDATE 2...
Rom has a watered down version of knox but no common KNOX entrie in download mode.
Q:Can i install a custom recovery is this rom?
A: YES.

what we really want to know is does this update have the locked bootloader? If so, then you may possibly forever be stuck with touchwiz and stock based ROMs..

Yes you could but be cautioned, that could lead to a bricked device. I'm not sure what a safe test would be.

try flashing custom rom maybe through custom recovery, or does that have same risks?

I will try to downgrade and see what happens.

If I'm rooted, can I just install regular? No custom recovery. Just stock everything except rooted.

did you brick your device in the process or did it just fail flashing & error out, or did it work but only flash 4.2 system leaving new bootloader intact?
so with this finding, just to be clear on this, no custom roms can be used for those who upgraded with new bootloader?
would it be possible to restore 4.2 rom backup of only system.img in custom recovery or will it not boot?
sorry for lots of q's

Yes I got what is called a semi brick when trying to downgrade the rom when flashing the bootloader partition. This is easily remedied by going into download mode and flashing kit kat.
The good news is once you got the new bootloader installed, it will be virtually impossible to brick your device by conventional means.
Yes, locked bootloader means you can't have custom kernels, but you can have customs recoveries and roms.
In theory yes, but as far as I know only bootloader above 4.3 are compatible with kit kat rom, it may work but you may find that certain drivers will nor work, like loss of wi-Fi may occur. I Know this from my experiences with the note 2 and s4.

Country: Baltic
PDA: T315XWUANA1
From sammobile
Link here
Sorry this link is still 4.2.2 jellybean link removed

UPDATE
@faria
ok, just restoring 4.2 system.img from twrp backup doesn't work, doesn't boot, blank screen after initial samsung logo, didn't try restoring 4.2 boot.img with it though, thought that had something to do with bootloader but reading up it doesn't appear to, so if i restored that as well maybe it would boot?
flashing custom roms like cm11.0 is still possible as you say & seems to work just fine using this new bootloader, even shows blackhawk kernel in settings/about, should this be possible as its custom kernel?
i didn't have to do anything at all different than when i was on 4.2, just flash custom rom through recovery as normal
no new entries in odin/download mode info screen, all lines still the same
now i don't feel so bad upgrading

@HavokbyName
Please download Device info from the playstore byjphilli85, run it and post your kernel version an boot-loader version.
I would not be suprised if we can also flash custom kernels to the tab as the Knox version the device have seems to be a watered down version.
Thanks for the feedback.

Bootloop: LG G2 D801 after TWRP install

Ok, so I just started to dig into my g2 today and decided to root it and such with hopes of trying out the resurrection remix rom. I followed this http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951 to root my stock D801 running 4.4.2 and it worked perfectly fine verified with the root checker app. I went on to install TWRP following this http://forum.xda-developers.com/tmo...l-one-click-freedom-tool-lp-30b-twrp-t3084474 which also worked fine so i booted into TWRP. First and only thing i did was create a backup. After the backup was done i rebooted and now I'm stuck with a repeating lg logo boot loop. I can still get into TWRP, and I can get into download mode so I'm not too worried. I tried restoring from the backup I made right before the bootloop started but it didn't work.
My question is what did I do wrong? Also, instead of going back to stock, could I just load resurrection remix onto the phone now and try to flash it even though its boot looping?

Did you actually ever upgrade to lollipop?
If not try flashing the 20g bootstack that can be found in the stock 30b roms by micromod...after that you should be able to restore your backup...

I did not. I was running on 4.4.2. I have since used the lg 2014 flash tool to flash the stock lollipop firmware, and subsequently followed the same process i mentioned above to root and get twrp installed. Now I have everything running alright, and a stable backup, but im running into issues flashing resurrection remix. I tried both the latest version on 5.1, and the newest version for 5.0.2. I first do a factory rest wipe on twrp, then i flash resurrection and the appropriate gapps ( 5.0 for the 5.02 rom and 5.1 for the newest one) both times i just get the lg logo after reboot. the logo stays for about 2 minutes until the screen starts to flicker and fade to grey. then i have to go back to twrp and restore.

I wish I could hit the thanks button more than once, you are awesome. Everything is up and running smoothly now. I don't think I would have ever figured out that a lollipop rom needed a kit kat bootstack and a jellybean bootloader to run properly. I don't even know how I'd go about finding that out. Thanks again.

No problem...by the way is download mode working after flashing 20g bootstack?...if not let me know as i made a modified version to fix but i haven't tested it yet...should work

maybe your problem is fixed by now, but did you try wiping cache/dalvik cache? That fixes 90% of bootloop problems for me.

[Q] [D800] Need help with getting back to stock AT&T and upgrading to Lolipop.

Hello, my D800 G2 is currently running Cloudy G2.2 and I have a problem where a certain part of my screen is unresponsive. I'm not sure if its a Hardware or Software problem; but I figured I would go back to stock and see if solves my problem. So I'm wondering if it's possible for me to flash stock and then upgrade the software to the official Lolipop update (OTA) or maybe just flash straight to Lolipop. Either way I would like to completely unroot and remove TWRP; and preferably have Lolipop in the end. Any insight on a fix for the screen is also appreciated, and thanks in advance for any help with reversion aswell.

Yes it is compatible
You can try

Thanks for your reply. Anything i need to know before installing the kitkat RUU? This is the first time i'm using an htc phone and i dont know much about it sorry. I was used to flash samsung roms but htc seems to be quite different. And by the way my phone is rooted. Should i unroot first?
Some more précisions about my phone. It is the htc d820u. And some people told me its the indian version. Will it still be ok?

U need not to unroot
make sure u have stock recovery that's it
it's same model that i have so go ahead without any worries
flashing of kitkat rom available is not necessary for upgrading to lollipop, you only need a 70 mb update before upgrading to lollipop

I downloaded that and installed it shows red exclamation mark.

Did you ever modify other files on your phone? Like modify sd card card permissions ect. I think i read somewhere that if your system files are modified you wont be able to update.

Lol no that means flash the official RUU on your phone so that you get a fresh install. Then update it will work.
