Restore to stock from GPE

purchased my phone T-mobile M8 used and it had been converted to GPE. There is a crackling issue with the top speaker and I'd like to return it for warranty repair. I haven't seen a great thread on converting a tmo m8 back to stock from GPE so I thought I'd share the research I have done and ask for help since I have not been successful yet...
With adb/fastboot, drivers, etc all in place...

Download the RUU

Run the RUU in Windows. Everything connects and it starts installing then - I get the Error 159 [IMAGE]
I have followed the steps above, downloaded twice, repeated and still...no dice. Any clue what I'm missing? I'm sure there will be other folks who need to revert and would benefit from this.

HTC ONE M8 Soft-bricked after GPE flashing- stuck in bootloader. Help!

Hello everyone,
Before I start here are some basic info
The phone is rooted and S-off.
CID: HTC__J15, later I have converted it to
Today I have tried to convert my HTC M8-Dual Sim to a Google Play edition through this thread
http://forum.xda-developers.com/showthread.php?t=2708589
However, after finishing the flashing process my phone was stuck in the bootloader screen, there recovery disappeared but I can flash it again.
I tried both the rooted and the un-rooted zips and they both gave me the same result.
After that I tried flashing back to the Sense firmware and stock rom, after finishing flashing it still was stuck in the bootloader.
If i tried to make a factory reset in TWRP it gives me (E: Resource type (font) failed to load)
Can you please help me, I need to fix it asap as I have a trip by next week.
Thank in advance

So I have tried to flash 2 roms and still have the same problem, the phone will not boot into the system. Just stuck in the bootloader.

Think you should have RUU for dual sim ,thread you followed is not for dual sim I belive

Tried to install VemonOne and now have a messed up phone with no OS

Ok, i tried to install VenonOne, it installed first time but my wifi didnt work, so i searched around and found out i needed to update my firmware, which needed S-off, which i cant becuase i dont have the money for sunshine. and problem after problem and following half arsed tutoials online solved nothing. i can only go to bootloader and recovery. not sure what to do,

You probably realize it at this point; but my rule of thumb is always make a backup before flashing anything (or at a minimum, have a known good backup or known good ROM ready to flash). Its got nothing to do with how "easy" a process is. Things can go wrong even with the simplest mods, to the most knowledgeable users, and even if you do nothing wrong.
You don't need s-off to update your firmware.
Either run a Lollipop (or Marshmallow) RUU intended for your CID (relock bootloader in order to RUU). Keeping in mind that this will wipe the phone.
Alternately (such as if there is no RUU for your version), restore a stock ROM that corresponds to your current firmware, restore corresponding stock recovery. Then do OTA update, which will also update your firmware.
After updating the firmware by either of the 2 above methods, just flash TWRP back onto the phone (in case of the RUU method, you'll need to unlock the bootloader again, before you can flash TWRP) and flash your custom ROM of choice.
If you do fastboot getvar all, and post the results (delete IMEI and serial numbers) we can offer some more specific assistance.

thanks for taking your time to help,

Use this ruu just relock bootloader it's ruu exe it's simple to use and let me know
https://www.androidfilehost.com/?fid=95916177934555499

RUU flash failed, stuck in fastboot s-on, relocked

I've spent all day trying to get my M8 (Sprint)unrooted and back to stock. I followed countless tutorials that involved locking the bootloader then running the RUU installer. Everything usually works up until i have to use the RUU, which always fails. I've tried a ton of different versions that all say they're for the sprint m8 but they always have an error and say to get the correct rom or something like that.
Any help is much appreciated

The above info indicates the phone is the US Developer's Edition.
The Marshmallow (last official version released) RUU is here: http://dl3.htc.com/application/RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4.exe
To install RUU, you will need to lock the bootloader with command: fastboot oem lock
If you still get any errors running the RUU, let me know. For some (most) US versions of the M8, you need to flash the Marshmallow firmware (radio, hboot, etc.) in order to upgrade to Marshmallow RUU. Don't remember if this requirement applied to the Dev Ed.

You sure the boot splash screen doesn't say HTC? Although the HTC logo pretty clearly says HTC, so I believe you when you say it reads "PTCi" but just want to confirm. If you are seeing PTCi, it seems your phone has a different ROM installed (than the stock HTC Dev Edition ROM). Which would agree with the fact the bootloader has been unlocked. I'm not famililar with PTCi, so I can't be sure what the ROM differences are. But flashing the RUU should at least not have any affect on network connectivity (as ROM does not affect the network baseband). And the stock Dev Ed ROM (which will be installed by the RUU) is a pretty good one.
