**You can begin the following process from any Build/ROM but you must already have Root Access**
**Required** FlashFire - Play BETA - PREVIEW
Downloads:
- G870A_OF3_Stock_ROM.zip (uploading...)
1. Place the ROM onto your device (use either internal or ext-sdcard).
2. Open the FlashFire app and "Agree" to the Terms and Conditions.
3. Press "(+)" twice to bring up the "Actions" menu.
4. Press "Flash Zip or OTA" and locate and select the ROM. Leave "Auto-mount" unchecked under the "Options" menu and press the checkmark to continue.
5. From the main menu Uncheck all options under "EverRoot" and set "Reboot" setting to *"Download."
6. Press the lightning bolt then "Ok" to begin the **flash .
7. Once the flash is complete and the device reboots into "Download" mode, flash the G870A_OC5_Bootloader using Odin's PDA/AP slot.
*If you are already on the OC5 bootloader, set "Reboot" setting to "Normal" and skip Step 7.
**The screen will turn black then display the contents of your system before beginning the flash. FlashFire will pause for about 1 minute while flashing the "system" partition.
Once complete your device will reboot and pause on the AT&T splash screen for about 1 - 2 minutes before completely rebooting. Done!
Tip: for blazing fast speed turn off animations from Developer Options and reboot!
Recommended: Package Disabler Pro to disable unwanted bloatware (root access not required).
Known Issues:
- None!
Notes:
1. The above process will not affect your Knox Warranty Flag.
2. The process will update your Modem, Non-hlos, System, Kernel, and Stock Recovery. The bootloader will not be flashed in order to allow for downgrading to previous firmware versions.
3. No need to wipe prior to flashing! The ROM will automatically perform a factory data reset.
4. If you do not already have root access (or to unbrick) you must flash the G870AUCU1ANE4_Full_Odin.tar using Odin's PDA/AP slot (Caution! Do not flash if you have taken the OF2, OF3 or OJ3 ota update) and root with TowelRoot, before continuing with the above process.
