[T-Mobile Samsung Galaxy S6] PS4AndroidHacker:
**This is just an idea I picked up from the Galaxy S5 threads that I use to deal with before, I take no credit for it and must divert all the credit to [MENTION=4708661]muniz_ri[/MENTION] for coming up with the original idea on the Galaxy S5, I just thought we could give it a try on the S6. I can not try this on my phone personally as I have already updated to 5.1.1 OF8. This process will utilize the FlashFire app. If somebody would like to test this method and give it a try to get results let me know. I'm just trying to get us S6 users to a point where we can update and keep our root. It was possible with my old S5 and thought we may be able to give it a shot here. You MUST already have Root Access to use the FlashFire app**

**Required**

An already rooted T-Mobile Samsung Galaxy S6

Set your screen timeout setting to 10 mins before beginning!

1. Place the ROM onto your device

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 OC9 or OCG bootloader using Odin's PDA/AP slot.

*If you are already on the OC9 or OCG 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 T-Mobile splash screen for about 1 - 2 minutes (10 - 15 mins for DeOdexed version) before completely rebooting. Done!

Tip: for blazing fast speed turn off animations from Developer Options and reboot!

Issues:

Unknown at this time,no testing has been done on devices yet,this is just a starting point.

Notes:

1. The above process should not affect your Knox Warranty Flag but no testing has been done as this is a concept still.

2. The process will update your Modem, Non-hlos, System, Kernel, and possibly Stock Recovery. The bootloader will not be updated 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. To learn more about FlashFire's capabilities on locked bootloader devices see here: http://xdaforums.com/showpost.php?p=60070810&postcount=2

5. I know the previous note said "Locked Bootloader" devices but I thought its worth a try on our phones.

6. This is VERY EXPERIMENTAL on our devices and would need somebody willing to try flashing a stock rooted ROM. I personally can't. I'm just trying to bring the capability to update without losing root on our S6's.

7. I am not responsible if you create an expensive paperweight, you're phone fries,you're phone starts dancing "Watch me whip,watch me nae,nae," etc.etc.
