Root difficulties flashing ROMs other than venom

[buMitch333]

So I've been trying to use the Sunshine utility to gain S-OFF as I have not been able to get Firewater to work. This is my second M8 and my first I was able to get S-OFF and install pretty much any ROM I wanted. If I remember, I successfully used Firewater with and nV M8 ROM but I cannot get nV to flash properly now. I just tried flashing a basic stock rooted ROM and got stuck at the HTC logo on boot. I guess what I'm asking if anyone knows what could be causing this issue as I'm tired of Venom and definitely want S-OFF as well.

Thanks!

I think your issue is that without s-off the kernel isn't flashing when you flash your rom. You need to flash your rom then use fastboot to flash the boot.img

So put a copy of the rom on your pc. Extract boot.img from the rom.zip and put it in your fastboot directory.

Use the command: fastboot flash boot boot.img

Your rom should boot up after that.

Great idea, reminds me of evo LTE days! Will give it a try! Much appreciated.

Well this didn't seem to be the issue as I still am not able to flash any other roms even after flashing the kernel... any other ideas??

OK so I think it may be an issue with firmware. I am currently on Android 4.4.2 running ViperOneM8 1.8.0. Any tips on upgrading? I was reading to flash a stock rom, accept an OTA, then move on to newer roms. Is this correct?

hi,
only info i know is that if you are going for a newer rom than 1.8 you need to flash the firmware first - can be done with s-on but is a bit more tricky than s-off so i hear
