I made this custom OG5 rom package for myself and I wanted to share it with those of you who want to stay on your older OB7 bootloader and be fully updated to Android 5.1 OG5. There is absolutely nothing changed from the stock rom/partitions except for the bootloader. This rom includes knox, itson, etc just like the official rom tar does. This simply gets you updated properly so you can proceed to root, flash recovery, flash rooted kernel, SuperSU, etc... and keep your unlocked OB7 bootloader. Please Note: If you have already taken either the OE1. OF5 or OG5 Android 5.1 ota update or odin flashed one of these official Samsung ROM rom tars, then you will not be able to go back to an older bootloader and this package will most likely not work for you. For the rest of us who where patient and who want to properly update to 5.1 and keep our unlocked OB7 bootloader then please keep reading.
The point of this odin package is very simple. Unless you flash the official 5.1 OG5 rom tar or take the 5.1 ota update from your phone then you will not be able to fully update to 5.1 the way it needs to be done. There are device partitions other than "system" and "cache" that must be written/overwritten with updated img.ext4's. Without extracting and comparing the img's there's no way to know what differences there are between the new 5.1 and the older softwares. So it goes without saying that it would be a wise choice to make sure your device has all of these carrier partitions etc updated for piece of mind. Again, I did this for my own personal use and not because I was bored. I want to share this with those of you who can benefit from it. So let's get started with the details/Instructions.
If you understand what the purpose of this odin package is then proceed: If not then do your homework or leave your phone alone. Here are the simple steps to fully update to 5.1 and retain the OB7 bootloader.
1. Install and use Odin 3.10.6
2. download and install 7zip
3. download and extract this OG5 odin rom package in a location of your choice. (VERIFY THE MD5 BEFORE YOU EXTRACT!!!)
4. Wipe your phone in your current TWRP or do a factory data reset in the stock bootloader. or proceed without wiping your partitions. (this can result in leftover data and cause issues so wipe if at all possible for a good clean slate).
5. Reboot your phone into download mode. (With phone turned of, press and hold the home, volume down and power button until the phone boots).
6. Open Odin 3.10.6 THEN connect your phone via USB and wait for it to connect.
Leave all defaults as they are and then press the big "AP" button to select the odin package you want to flash then press start. Wait for it to finish and it will let you know when all items flashed successfully. Unplug your usb and wait for first boot.
7. Setup your device as usual. Done.
You are now fully upgraded to Android 5.1 (OG5) with all partitions correctly written to your phone as per the OG5 update.
