[Sprint HTC One (M7)] Goto_End:
---- EDIT ----

I followed the tutorial by [MENTION=4609217]BD619[/MENTION] for fixing a soft bricked CDMA device after flashing a GSM ROM. Phone is fixed.

I posted this thread over in the general HTC One forum, and it was suggested I post here. So, sorry in advance for the dupe (I also can't post links yet, so I'm going to copy/paste as much info as I think is necessary).

---Original Post---

Ok, so I have admittedly really screwed up and I'm hoping someone here (or multiple someones) can help me out.

My major screwups:

No nandroid backup.

No s-off

I have Sprint

Current State:

I can get to fastboot, recovery and adb works fine. But no matter which recovery/rom combination I try, I get the same end result. My phone will boot to the "HTC One" screen, then go the green HTC logo/white background screen then reboot. Sometimes it stays active long enough to begin the "Welcome to Android" stuff (pick your language, wifi connection, etc...), but not nearly long enough to get through all the screens.

What I've tried so far:

Multiple recovery options including CWM and TWRP. CWM versions 6.0.4.3, 6.0.4.5 touch. TWRP versions 2.6.3.3, 2.6.3.4, 2.7.0.0.

ROMS: ARHD 31.6 and 62.0 (I know this doesn't work with Sprint), Viper 6.1 and some "stock" rom I found somewhere (filename One_4.19.401.11_odexed.zip).

I don't remember exactly the order, but I know I did TWRP 2.6.3.4 and ARHD 62.0 first. Then did Viper 6.1, then ARHD 31.6. Since then, I've tried every combination of recovery and ROM that I can think of.

Here's getvar all:

(bootloader) version-bootloader: 1.56.0000

(bootloader) version-baseband: N/A

(bootloader) gencheckpt: 0

all: Done!

finished. total time: 0.040s

I'm willing to try anything at this point. So suggestions are welcome. You're also welcome to berate me for the above mentioned screwups, but it won't be very helpful.

TIA

---Update---

Downloaded the 2.6.3.0 from the link [MENTION=2605798]nkk71[/MENTION] provided in the original thread (checked md5). Flashed recovery. Did an adb push to get the Viper ROM (also checked the md5) back to /sdcard and flashed the ROM. Same results as before.

Additional info:

Sometimes I will get "com.htc.htcdialer is not responding", sometimes not.

The screen will timeout on the green HTC logo screen. If I hit Power to bring it back to life, I have to "pull to unlock" and either the logo screen is still there or it's made it to "Welcome to Android".

I actually got to the Welcome screen this time. Picked the language, wifi network and started with my Google login before it rebooted.

Maybe an incompatible ROM issue? If so, I'm out of ideas as to what to try next.

I've downloaded what I believe to be the RUU for this model phone, but since I can't see the phone in Windows, I haven't even tried the RUU.
