This was taken from a system dump of the OTA and made into a complete flashable rom. This is a good starting point for devs and for users that just want root. It does not include the bootloaders or modem. I've pulled the modem but I'm weary to flash it.

What's included:
SU installed
Busybox installed
Proper insecure kernel
Deodexed

DOWNLOAD



Here is the UCMG2 modem file that I pulled. This is just the modem.bin, it is not flashable!
PLEASE USE AT YOUR OWN RISK! I still have note tested it!

The script will check the file integrity so if the checksums do not match it will abort.
As always use with caution.



Here is the complete UCDMG2 firmware minus recovery

This will update your phones firmware, bootloader, modem.... while retaining your custom recovery. Nice easy way to update without Odin.

  • 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

Credit to mnasledov for the flash script.

Simply flash in recovery.

Nice! Will users have to be on the DMG2 baseband for data, wifi, etc to work? That is the case for some updates, but not others. I don't know about this one.

Would you be able to send me the modem file? All I've been able to get is a .bin.p file to patch from the previous modem, and I don't have an AT&T device to run the patch against.

Maybe it's just to early for feedback? I've been looking around some but haven't seen anyone post any definitive changes from 4.1.1 to 4.1.2.

I have not tested that yet. I accidentally cleared my sdcard including my nandroid backup so I've been trying to get this up to the state my backup was.
If anybody has successfully flashed from LK3 please let us know!

Of course there's no way to actually tell so it may just be placebo but it feels terribly slow and almost grinds to a halt at some points. There's also many missing features and I have to touch the screen mulitple times for a response some times. Of course all of that is not true and if you've used the t-mobile port or the i747m builds then you'll get a pretty good idea as to what this offers. If you haven't then you should try it out and see how you like it.

This modem file seems overly large, what method did you use to pull it? The best way (from a device already running the new modem) is to run dd if=/dev/block/mmcblk0p7 of=/sdcard/modem.bin to get a modem.bin on your internal storage. You might need to adjust the output path depending on your filesystem layout.

EDIT: Never mind, yours is just padded to the full 60MB. It's a good rip. Uploading a flashable version now, you can find it in the modem thread in my sig.

Yes, multi window it's there. Along with some AT&T apps. Still no Mobil Data option in task bar.

That's the method I used. I was a little worried about the size, but I'm glad it works
