Here you have the Unofficial M919NUVUAMF2 firmware made by me flashable with Odin working 100%. First of all I want to thank techguy1214, exel and dulal18, without their files and threads would have been impossible for me to do it. After many unsuccessful flash attempts using the firmware provided by techguy1214 in this thread: http://androidforums.com/metropcs-g...ropcs-m919n-uvuamf2-stock-odin-flashable.html and using the files provided dulal18 in this thread: http://androidforums.com/metropcs-galaxy-s4-all-things-root/773303-guide-how-return-stock-if-you-have-flashed-tmobile-odin-tars.html Using heimdall I opened the .pit file included in dulal18's thread and found that there is an extra partition for sbl1.mbn, this file was also present in BOOTLOADER_M919NUVUAMF2... and was not included in the .tar that was posted by techguy1214/exel in their post. What I did was to decompress all files posted by dulal18 and repacked in a new .tar file with similar structure as exel .tar but adding sbl1.mbn using Cygwin. Flashed with Odin 3.07 as PDA and everything went ok. Now I have a brand new perfectly working unroot MPCS M919NUVUAMF2. The only downside is that it shows “custom” in system. Link (thanks nuttmeg) https://www.copy.com/s/X073cR993PrD/M919NUVUAMF2_Non-Official.zip 1. Download the above .zip file and extract the .tar file in the archive and save it somewhere 2. Reboot your phone to download mode. To get download mode shut down the device. After it shuts off completely simultaneously press the Down volume key+ Home button + press the power button . 3. Start Odin 4. Click on the PDA button and browse to the .tar file that you extracted in step 1 and select it 5. DO NOT PUT .PIT FILE AND DO NOT TICK REPARTITION 6. Connect the USB cable and wait for the ID:COM section to turn blue 7. Click start to flash 8. Do not disconnect the cable or turn off the device once the flash has started, it’s going to take some time to flash, when finish exit Odin and disconnect USB. 9. Let the phone start and Voila!!!!!!
