[Q] Reverting back to Stock from GPE - all of my research

I 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 back to stock from GPE so I thought I'd share the research I have done - even though I have not been successful yet...
With adb/fastboot, drivers, etc all in place...

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.

When I converted back I just followed this without any issues. http://forum.xda-developers.com/showthread.php?t=2733523 I didn't got as far as using the TMO RUU though.

Did you relock the bootloader before running the ruu? For whatever reason it needs to be relocked before an ruu will complete

Is that the Sprint H/K model? Your getvar only shows what you have now, not what you had before. But I believe your MID is H/K?

how long does it usually take, as it said disable hibranation and standby off, so im assuming a while.

Change your MID to WWE to run that RUU, 0P6B10000.
[how to] change your MID without an eng bootloader In the section "HTC Europe MID" . Copy and paste commands, make sure you have no extra spaces either before or after command. Putting it in manually and you do it wrong might give you more problems.
Change CID to HTC__001
fastboot oem writecid HTC__001

had errors but fixed, now to try the RUU out.
EDIT:
RUU was successful, i now have wifi, anything else i need to do to be back on stock or is that it? will i be able to upgrade to Android L?
do i need to lock my bootlocker?
does RUU install a stock recovery?

So it updates successfully, however when I go into Google Play Movies, only the rent option is available, I buy movies a lot as I own Chromecast, anyone know why buy option would be gone? Checked other android phones in house and they all still have buy options.

Tried to downgrade to stock - stuck

Hey XDA,
I have a bit of a problem! I was trying to S-OFF my Tmobile m8 phone (ViperOne 2.5.0) so that I could upgrade to the latest and greatest. I installed Sunshine and was told my ROM wasn't compatible.
I followed the instructions here: http://www.android.gs/downgrade-t-mobile-htc-one-m8-to-official-stock-firmware-with-ruu/ to get back to stock so I could S-OFF.
Basically, relock the bootloader (done, successfully - shows Relocked) and ran the RUU utility. The RUU utility says that it's not the right version - I downloaded RUU_M8_TMOUS_1.57.531.7.exe. Now, my phone is stuck in fastboot/hboot and when I try to reboot, goes right back into fastboot. I have no idea what to do from here. I can't get into recovery to restore an image. I can't "fastboot oem unlock" to see if that helps - it fails.
Any ideas?

Your issue is that you are trying to run an RUU for an older version (4.4.2), or that you are not on T-Mo US, but on an International/European version.
If you are in the US, run this RUU instead. It will jump you up to Lollipop 5.0, and should also fix your issue.
The above link is to HTC's US website, and is the official 4.20.531.4 RUU. You will want to scroll down to the manual system update instructions. The download is at the bottom of the page.
Good luck!

Yep. That was the problem. I can tell from your bootloader version that you are on 4.4.3 firmware. You can only downgrade if you are s-off.
If you want to get S-Off, after running the RUU would be a good time to do it. It works best when on the stock ROM, but will also work with a near stock ROM such as MaximusHD.

Actually, the MID shouldn't matter.
With SuperCID, the MID check is bypassed. It's worked that way with the M7, M8, and M9. With the HTC 10 though, MID must be changed as SuperCID doesn't bypass the check.
Flashing the latest Verizon firmware should be enough. The RUU would only be necessary to run a stock ROM. If a custom ROM is going to be installed, the firmware flash will be enough.
He/she should make sure to flash a full stock firmware and not a "no wipe" version though, since the boot.img (stock kernel) will be removed on a no-wipe firmware package.

@xunholyx
thanks for make it clarity
but is there any thing else should be worried about after flashing WWE firmware over Verizon firmware
and i think he need the stock RUU

Well, flashing GSM firmware onto a CDMA device is NEVER recommended, so I do understand your thoughts here. And I do agree that running a RUU would be the best and cleanest way to convert back. Changing the MID back to Verizon's should not be necessary, but truthfully there is no reason not to. The OP should stick to Verizon firmware only, so the MID being changed back to 0P6B20000 would probably be a good idea. :highfive:

Well, I hope they know what they are doing. Because the phone was all kinds of messes up, and not every repair person would know how to fix it (if its even fixable). Someone at some point (if not you, then a former owner) tried to flash the unbranded Euro firmware to this Verizon device. The result is usually a radio brick, and the damage may be permanent.
Most that person can do, is flash the Verizon firmware and RUU (as others have stated) and hope it works properly after that. Unless they are going to replace the whole mainboard.

You have the US Sprint version. US versions can't update OTA unless you are actually connected to that US carrier (in your case Sprint).
So therefore, yes RUU is the best way to install an "official" update.
You can find the Sprint RUUs here: https://forum.xda-developers.com/showthread.php?t=2729173
You can update right to the last version (Marshmallow) 6.20.651.3 without flashing any intermediate versions. You will however need to flash the 6.20.651.3 firmware before 6.20.651.3 RUU (requirement peculiar to US Marshmallow RUUs).
Instruction on how to flash 6.20.651.3 firmware are on the same thread as the RUUs.
Keep in mind that flashing RUU will wipe the phone. So backup any data you want to keep to SD or off the phone (cloud, computer) before doing any of the steps.

It won't "fix" the issue of not getting software updates OTA. It's not so much an "issue" as it is just a fact of the US versions of the M8.
But it also doesn't matter. The RUU I suggested will put you on the last version released by HTC (Marshmallow). There have been no updates since, and there will be no more updates.
