**You can begin the following process from any Build/ROM but you must already have Root Access**

**Required** FlashFire - Play BETA - PREVIEW
1. Join the G+ community using the same Google account as you're using for Play on your phone/tablet Here.
2. Sign up to receive the BETA versions from Play Here.
- Use the link provided after sign-up to download the app.

**Caution!** The following process is only for the G900V Verizon S5 variant. Use on any other device may result in a hardbrick!


Download:
- G900V_OC4_Stock_Rooted_ROM

- G900V_OC4_Stock_DeOdexed_ROM

Set your screen timeout setting to 10 mins before beginning!

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. Select "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 use default "Reboot" setting.
6. Last, press the lightning bolt then "Ok" to begin the flash .

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 Verizon splash screen for 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!

Known Issues:
- None!

Optional - Enable Native Tethering:
- G900V_OC4_TetherAddOn (Flash using FlashFire's "Flash zip or ota" option).

Notes:
1. The above process will not affect your Knox Warranty Flag.
2. The process will update your Modem, Non-hlos, System, Kernel, Stock Recovery, and Bootloader to OC4.
3. No need to wipe prior to flashing, the ROM will automatically perform a factory data reset. If you prefer not to wipe User Data replace the Updater-Script in the ROM's META-INF/com/google/android folder with the version attached to this post (remove ".txt" extension before placing in folder). Bear in mind that carrying over incompatible User Data from a prior Android version may cause issues.
4. If you do not already have root access (or to unbrick) you must flash the G900VVRU1ANCG_Full_Odin.tar (flash in Odin's PDA slot(AP in Odin v3.09+)), root with Towelroot (this version does not require internet access), then proceed with the above process.
5. To learn more about FlashFire's capabilities on locked bootloader devices see here: http://forum.xda-developers.com/showpost.php?p=60070810&postcount=2

Thanks. I did your previous update with this method, and it worked great. Can you give the steps that are needed to get to where you need to be to now install this update? I think I know, but I'm not sure. Also, what about apps and settings? It does not seem they are preserved. It looks like the previous write up has been edited and no longer includes these steps. I had no problems with this part. Is it still an option to do that? Thanks for the awesome work!

So there's no need to flash a firmware or kernel in Odin after flashing the rom? Are we still going to be on 0A8 baseband? Or should we flash the OC4 kernel?

awesome @muniz_ri ! was just helping a family member update to the new lollipop and i saw this. gonna do some tinkering with safestrap and try and see if i can see whats breaking it on lollipop.. fingers crossed
No worries, good luck with SS.

Also fyi.....there is a guy in the N900V forum that has developed a safestrap replacement called multisystem. He is waiting for 5.0 before releasing and claims it will work on 5.0. If so, it can likely be easily ported to the S5.

Got it. I did see that. I guess it is just that simple. I thought there might be a little more detail needed, but I will give it a shot. Hopefully safestrap comes to lollipop one day to make it a little easier!

After flashing the ROM you can just reboot, no need to re-flash the OC4 kernel since the new ROM already flashed it.

I have run into a problem i can't figure out. When i try to run safestrap it just wont boot into it when i boot from the app. Have tried it many times. Thinking back wasn't safestrap broken when you are on 5.0? I went from kit kat, rooted and did the keep root tutorial to have it in 5.0. Not really sure what to do.

Safe-strap doesn't work on 5.0. You have to flash G900V_NK2_Stock_Kernel to access it.
