Root Updating Very Old ROM to Current

[md99]

I am running Viper 1.7.0 and have been for a very long time. I decided I should really update but started looking into it and it looks fairly complicated. It looks like I may need to unroot completely then basically start over after updating firmware? I realize I have some research to do, but could someone give me the quick cliff note version and point me in the right direction? Thanks guys.

Do you have S-Off? If not, get it. You can manually update your firmware version then without needing to go back to stock then update the ROM as needed.

http://theroot.ninja/ for s-off, far easier than what you went through with your LTEvo.

If you're still on Sprint, get s-off, load Captain Throwback's firmware update on your SD card, boot phone to fastboot, let it update, done.

Thanks guys. I've got s off. I appreciate the direction. I've been rooting and playing with various roms and tweaks since my og evo but I'm rusty with it being so long. I'll let you know if I run into issues.

Can you point me to a thread to find Captain Throwback's firmware that I need?

Yep! Be sure to get the international firmware when you need it.

S-off, accept no substitutes.

mmm.....seems that the capt.s file is just for sprint, not international :/

I've used this method twice Dan, worked a treat both times

There's no fun without a wee panic attack.

Have also used one of Sneakyghost's zip files from here as he rolls them up so you can jump straight to latest

Used both with no issues. Just scroll back through cmd prompt to make sure there are no fails before rebooting bootloader, simples
