PLEASE READ ENTIRE THREAD BEFORE ATTEMPTING!! I AM NOT RESPONSIBLE FOR ANY DAMAGE
FILE WAS DOWNLOAD FROM AT&T VIA OTA UPDATE FROM MY MEGA & EXTRACTED FROM THERE - I527UCUBNE7 CFG FILE OTA UPDATE
I only recommend running adb sideload to install.
ADB SIDELOAD DETAILED INSTRUCTIONS
- Make sure USB debugging is ENABLED
- Reboot device into recovery
- Plug device into computer
- Select adb sideload from your devices recovery screen (drivers might need to install, wait for this and then continue)
- load up command prompt for adb
From here I will give examples (adjust according where your file is stored)
As example say I saved my file in my documents folder this would be the command to sideload
adb sideload c:/users/owner/my documents/ATT OTA 4.4 UPDATE.cfg .............you can rename the file whatever you want but I changed the name for confusion as to what it was.
The file will start to load onto the device and show percentage in adb until upload is complete. Once the file is loaded your device will start the update process. If it fails it will show where it stopped at most likely being that a factory file is missing or changed. Everything must be original from previous mr2 firmware.
AGAIN IF YOU REMOVED, MODIFIED, FROZE APPS LIKE KNOX MOST LIKELY YOUR UPDATE WILL FAIL AFTER 25-30%. FOR BEST RESULTS YOUR ROM MUST HAVE ALL ORIGINAL FILES. THIS UPDATE SCANS YOUR FILE SYSTEM TO ENSURE NOTHING HAS BEEN CHANGED. ANY CHANGE WILL CAUSE A FAILURE.
IF YOU GET AN ERROR DURING UPDATE - INSTALL INSTRUCTIONS IF YOU GET AN ERROR
- Download mr2.tar.md5 file located in my signature under galaxy mega repository
- Install via Odin & make sure "Auto-Reboot" is UN-CHECKED
- Once install is finished reboot device into recovery
- Select adb sideload install then follow the steps above to install update via sideload
THIS UPDATE IS NOT ROOTED OR UNLOCKED. INSTALLING WILL CAUSE YOU TO LOOSE ROOT!!
IF YOURE NOT SURE WHAT YOUR DOING - DONT DO IT - RECOMMEND REMOVING BUSYBOX - ROOT BEFORE INSTALL -
AT&T I527UCUBNE7 OTA UPDATE - CFG FILE - DROPBOX CURRENTLY DOWN DUE TO CONGESTION
