[Q] RUU Fails (155) with S-On and Relocked Bootloader - T-Mobile HTC One (M7)

So I was an idiot and wrote S-On to my phone before I was finished flashing the RUU. I have tried firewater (obtained with Wayback Machine) and rumrunner, and both failed. I am on an old version of AHRD and HBoot 1.56. Every time I try to flash the latest RUU (6.10.531.10) from htc.com, it fails with Error 155 after trying to check the signature. I have also tried extracting the rom.zip and flashing that, but I get the same result (fails after trying to check signature).
I have tried S-OFFing with every method I've found. Using Arch Linux, using Windows, using old ROMs, new ROMs, AOSP, Sense, making sure I always use an unsecured kernel, etc. firewater deletes itself every time I try to run it, and rumrunner fails after 8 tries. I don't want to spend $25 on SunShine, so I'm looking for every alternative.

You might try an older RUU 5.14.531.1 first before the newer RUUs.
As far as obtaining S-OFF, with your hboot Sunshine is your best option.
