Brick Phone - EFS delete - no S-Off topic

Hello Guys,

Please HELP ME!! :(

At first, sorry for my bad english, i´m german.

I have a HTC One Vodafone, on hboot 1.57 and CID VODAP102. currently running CM12 5.02

So, during the Root-Process the EFS-Partition was delete and so my HTC has no IMEI Nr oder Baseband Nr. and of course i have no backup.. nothing...

i wanted to restore or repair my EFS partition as mentioned in this thread http://forum.xda-developers.com/show....php?t=2399037

but in my phone is no /data/nvram/md/NVRAM path .. i think because i have not the stock ROM installed, right?

So i decided to flash the right Stock ROM like described here: (sorry, german site) http://www.android-hilfe.de/anleitun...-swisscom.html

BUT for doing that i need to S-OFF my phone, i really tried everything, firewater, rumrunner, revone... it seems like it is impossible for me..

Rumrunner says, my combination of Kernel and ROM is not supported.. WTF? which combination do i need??

So, my main problem is to restore the EFS.. Is there any simpler way to do that??

please help me guys....

Thank you

Best regards Bischii 02
