[Solved] Issues restoring U11 to stock

[tamudude]

Trying to restore my wife's U11 to stock in preparation for Pie. It the US Unlocked version. Every RUU I have tried from here https://docs.google.com/spreadsheets/d/15JL3tRWDSVOUKo_revEYtQ_tRcOSJ0vWcvk8a7TK8Hk/edit#gid=0 gives me an error. The bootloader is relocked and I have tried both vanilla fastboot and fastboot RUU.. I have also tried the SDCard method (renaming to 2PZCIMG). Any ideas?

Errors I get are:
22 RU Header Error or 9 RU Security Fail

Details of phone:
(bootloader) kernel: lk
(bootloader) product: htc_ocnwhl
(bootloader) version: 1.0
(bootloader) max-download-size: 1560800000

(bootloader) slot-count: 0
(bootloader) current-slot:
(bootloader) imei: <SNIPPED>
(bootloader) version-main: 2.42.617.1
(bootloader) boot-mode: download
(bootloader) version-baseband: 8998-002772-1712011153
(bootloader) version-bootloader: 1.0.0.0000

I have the same variant and had a similar error with the SD card method. I ended up running the 2.42.617.7 exe from my computer and that worked. As soon as I got the stock ROM setup, I was able to take the OTA from the phone. Now running fully stock Pie, rooted with Magisk and TWRP installed, but that doesn't yet work for us, so not able to backup your ROM, so flash mods carefully. Good luck!

Thanks for the reply. What mode does the phone have to be in? I have tried in Download Mode, Recovery Mode and rebootRUU mode but running the exe does nothing once I go past the "Agree" to terms and conditions stage from the exe. I have installed HTC Sync Manager installed. What am I doing wrong?
In recovery mode I get a red exclamation and an error on the phone saying "Your phone is corrupted and cannot boot". Is that the problem?

Fully booted, unlocked and USB plugged into your computer. The exe should recognize your phone and boot it into the right mode for the install. Be patient and let it do its thing. It will take ~10 mins I think.

Finally got it figured out. The reason the exe would not progress was because it needed Visual C++ 2008 x86. I came across this post https://forum.xda-developers.com/htc-10/help/htc-ruu-windows-10-x64-x86-issues-t3690998 installed all the programs listed there and the RUU then proceeded. Eventually it threw error 170 at me. I then booted the phone into Download Mode and was able to get the ROM installed. BTW, this was with the 2.42.617.7 exe. Immediately thereafter I got the update to Pie so all is well.

That's great, congrats on sticking with it and figuring it out! I like the Pie update, especially the notifications, but they are somewhat of a challenge to get fully set up across the apps you want. Please let me know if you're able to set your SD card as your camera storage. This worked on Oreo, but cannot get this to work on Pie. I tried formatting it from the phone to no avail. The phone does recognize the SD card overall, but there does seem to be issues. I really hope devs are able make ROMs with these U11 updates. I've always used Viper ROMs and love the mods and extra features over stock. Without TWRP fully functional, this might not happen anytime soon.
