Has anyone tried flashing the GPE ROM.. I am a noob with HTC.. Been a Samsung user for years..
What is ruu?
What is S-off?
Is there anything like Knox counter on HTC that should be considered a risk?
Can anyone point me to the directions on converting Tmo M8 to GPE M8
Thanks in advance..

You can flash GPE roms just fine without converting. I am currently using a GPE rom myself and have not converted. I would only convert if you want the latest google updates. You probably need to remain as Stock GPE for those also. Also, once you convert to GPE, you cannot flash sense roms or go back to sense until a sense RUU is released. As of now there are none.
RUU stands for ROM Update Utility. Essentially it overwrites your all system partitions with stock partition files including hboot, recovery, radio, etc and software or ROM.
S-OFF stands for Security OFF. It disables security checks for things like CID (carrier identification) and allows you easier access to overwriting certain system partitions. This is both good and bad since, if you don't know what you are doing, or don't read/research enough before overwriting some partitions, you could end up with a brick, however, at the same time, there have been occasions where S-OFF prevents bricking as sometimes, HTC's own RUU's do not finalize checks until after flashing or wiping partitons, leaving you with a brick.
I think my information is pretty accurate, but anyone should feel free to add on if I am wrong about something or am lacking in some details.

Bear with my ignorance my friend..Thanks for the info.. Does that mean a stock rooted gpe will still get OTAs?

OTAs rely on stock recovery so you could use a custom recovery to root and then flash back stock recovery to receive OTAs. In short, Yes, you could/would still get OTAs.
I could be wrong but i believe that yes even with the rooted option you will still receive OTAs. Now if you have custom recovery then you will have to flash gpe recovery to take the OTA. Here's a link to the conversion thread

Wonderful.. Thank you guys.. Has anyone tried this on T-Mobile M8?

I figured I should also post that typically an RUU cannot flash older versions.. or backwards.. You can only flash the same version or later. IE: You cannot flash backwards to version 2.0 if on version 3.0. If on Version 3.0 You can flash 3.0 and higher. However, with S-OFF it is possible to flash older RUUs.

Hello I just bought htc one m8 I want to root bad but I just want to make sure is their a way to go back to stock with s off yet?
No RUU is available yet. There are stock kernel files and you can make a backup in recovery of stock rom. But, if you convert to Google play edition there's no way to get back right now.

Correct, but only for now. Just waiting for the RUU to be released.
If you unlock with HTC Dev, the bootloader says unlocked or relocked (if you relock it).
To get locked again you need S-OFF.
However, I've seen S-OFF is (almost?) achieved, but no tutorial about restoring the lock flag.
There is some misinformation going on in here. You can flash a GPe ROM, and still be able to flash back to sense. However, if you flash the GPe RUU, then you are stuck until we get a sense RUU. Also, s-off has already been achieved, check the original development thread.

You can install a GPE Rom and then flash back to a Sense Rom no problem. What I was saying is if you do the full GPE conversion by flashing the GPE RUU, there's no way to get back to Sense until an RUU is available.

I know we can S-OFF, but after that, how do we set the device back to Locked instead of Unlocked or Relocked?
IF you have an unbranded EU handset there is a way to get back to 100% stock with a bit of imagination...
1. Flash the stock odexed 1.54.401.5 ROM @mike1986. provided HERE
2. Flash the stock 1.54.401.5 recovery provided HERE
3. Relock the bootloader (or, if S-OFF, reset the tampered flag and lock it again)
You could also look into flashing the 1.54.401.5 firmware package to be ultra-sure you have everything done but if you were already on 1.54.401.5 before going custom it's not really required
That should do it...
confused a bit?
Dont want sound like a newbie but so if I unlock the bootloader and turn s off then its rooted and I can flash any recovery I just want to clear things real quick if I want to restore it like from the day I got it its possible if I follow your directions? I got the atnt version to I know I sound like super newbie but Its just a little more complicated to do this on htc one then it was when I had the s4 no doubt tho htc one m8 is amazing!!!

But.. how?
I mean, I know how to relock (there's an HTC official method), but if i'm S-OFF, how can i lock?
There's a thread on removing tampered and showing locked in android Dev section. I believe it just flashes a modified hboot file. Then you just need to s-on:
Fastboot oem writesecureflag 3
Then lock your bootloader which you know how to do.
There have been issues with running an RUU after messing with your bootloader while S-on with HTC Phones in the past so to minimize possible bricking be sure to see your CID back to its original if you changed it and possibly even leaving the phone S-Off if you plan to continue using it after returning to stock.

No, you can lock it first as doing the normal will show 'relocked'. When S-OFF, you can set it back to 'locked' and then S-ON again (if you really want to). Guides are in General on how to do this
Hello Folks,
I'm helping a friend to mod his m8 , he has installed 4.4.3 OTA I know I can unlock the bootloader via HTC dev then custom recovery and wakesauce to gain su acess, but can I use firewater to SOFF the phone after installing 4.4.3 OTA , I have read somewhere HTC patched stuff and firewater does not work on 4.4.3 devices?
Please advise ...

You don't need HTCDev if you use SunShine, as SunShine gains S-Off AND unlocks the bootloader. Following this way HTC don't come to know that the device has been changed. Thus you would not have any problems regarding warranty

Yes but to flash AOSP/GPE ROMs could easily lead to problems if it is done wrong. For GPE as far as I know a conversion of the phone is needed, as the partition sizes are different. During this process the hole firmware has to be replaced by the GPE one with the black HBoot as well. So do carefully read the conversion threads if you are coming from a sense ROM!

The partitions are only altered if a full conversion (by RUU) is performed. GPE based custom ROMs will run fine with no conversion (no partition change or hboot change required); as will any AOSP ROMs.
Hi,
i was trying to do the HTC ONE M8 OTA but it failed due to the HK mode being installed. At first i though that just restoring the stock recovery would be enough but then found out that the HK mod also made the update impossible. How do i completely uninstall/remove the mod so i can proceed with the update? I would like not to have to flash the stock rom as i don't want to lose my data. I know i can do a backup with the HTC tool but that won't save the sms conversations, whats app conversations etc.
I have a Rogers HTC ONE M8 GSM.
thanks!

Just dirty flash the stock ROM again. i.e. Flash it over your current ROM.

Unless you had other mods installed, it should not remove anything. Just don't wipe your device and flash it.
I just got a Rogers HTC One M8 -- I was looking into installing the HTC mod but I don't know what S-Off is, and why that term is exclusive to HTC devices.
On another note, is the HK mod worth it? And what are the most popular reasons for rooting the M8?

first app i install after rooting/formatting my phone is the titanium backup
Also the H/K mod is subjective but i find myself going back to BoomSound.
S-Off is security off where you won't be able to have full access of your phone like flashing AOSP ROMs etc. but however, you are still able to flash the HTC One based firmware. install custom recovery and do nand backup etc
I am currently s-on but running the GPE rom. Would I experience any benefits by s-off'ing and doing the GPE conversion? Or is there no difference other than OTA ability?

It also changes the partitioning, making the system partition smaller, and the user accessible storage partition gets bigger.

As soon as you are S-Off, OTAs won't matter much. You can update your firmware manually almost always before your carrier does (unless your carrier happens to be first to update), and install a ROM based on that firmware within a day or two after it is released.

I mostly agree (and personally not much of an OTA person). But for some reason, some folks still like to OTA even after s-off, bootloader unlock, etc.; which is something I never really understood much.
Also, GPE typically gets OTAs before any version. Although there is always a chance that you can flash a ROM even before the GPE update; if there is a "leak".
I have a Sprint HTC One M8 and I am thinking about converting it into a Sprint HTC One M8 GPE. My only question is can I use the Sense RUU (off the HTC developer website) to restore it back to stock. The reason I ask this is will the Stock RUU still work with the GPE bootloader and recovery?
Sent from my 831C using Tapatalk
If you flash GPE firmeare, you can't flash sense ROMs. GPE uses a smaller system partition. Sense needs like 1.5GB and GPE only uses about 1GB. But if you flash a sense RUU it should flash the sense firmware which would give you the proper partition sizes.

You don't convert a Sprint M8 to GPE. You just flash a GPE ROM onto it. That won't change any partition sizes. The GPE "conversion" won't work on a CDMA M8.

Because it's a different variant. Stock GPE won't even boot on a Sprint M8. That's why the ROM has to be ported in the first place. Once you convert, the ports likely won't even fit because they're made for the standard (Sense) partition size.
