No soff on stock ROM (hboot 1.55 - mainver 220.127.116.11) with rumrunner 0.5 or firewater
Edit : mistyping in title hboot is 1.54
I am at the very first stage of fully debranding my brand new Orange phone (restore HTC stock through RUU and get OTA updates, locked (and not relocked), not tampered).
I am unable to Soff with rumrunner 0.5 or firewater though I am very careful with all the prerequisites. I tried several times. hboot and mainver are a bit old (though mainver is uncommon) and other have succeeded to soff with similar versions.
What should I do ? I am OK to flash anything as soon if I am 100% sure to get S-on at the end. Or I relock, stay with Orange and operator's OTAs.
Thank you so much for your expert advice.
