Still Having Issues with TWRP
You may or may not have seen my posts regarding 188.8.131.52 TWRP and how it became unresponsive to touch inputs as soon as you modified the install of Android in any way (factory reset fixes the TWRP unresponsive to touch issue on my phone for some reason). As discussed there I re-flashed 184.108.40.206 as per instructions several times, always with the same outcome, so I have replicated this across multiple downloads/installs and with different versions of CyanogenMod installed (11 release channel, 12 Nightlies). Someone recommended to me to try the latest 220.127.116.11 which seemed to be working for everyone.
After having been away for a long time I just got a chance to start again with my phone from scratch and did a full format of everything and flashed the new TWRP 18.104.22.168 at the top of this thread. I now have a new problem...if I try to boot into it, the phone just gets stuck on "This is an experimental buid...HTC...etc" notice in red on a black screen, and nothing happens. So I seem to be locked out of TWRP, and actually I cant get to fastboot/HBOOT either (i just get stuck on that same screen). Volume up and power, volume down and power, and volume and volume down and power all produce the same outcome now. ADB commands also cannot get me to it ("Waiting for device" error now).
Fortunately from within the CyanogenMod Rom 12 I installed (an old nightly release), I was/am able to download updated nightlies and the installer does manage to successfully update the phone to the latest version, including it going through a screen that appears to be an HBOOT/fastboot screen, however it is all automatic and part of the ROM update process so it is not a method I think I can exploit to get to these parts of the hardware/software environment. Not sure what the update process is doing that gets it past the black scren with red writing, but it does.
U-ra, you have been a champion and thank the unknown that we have someone working as hard as you are on developing options for our device, so this is in no way a complaint or criticism, I am only intending to contribute constructively if only to let another user with my issues know they are not alone. That said, any tips on how to get full TWRP functionality back would be appreciated.
