Install 4.4.3 on rooted HTC One M8

Hi,
I did a few searches but didn't find a solution.I have a developer M8 rooted and S-off. It's running 4.4.2. How do I go about installing the 4.4.3 OTA HTC apdate? Would I loose root and S-off in the process? Do I need to go back to stock to apply this update or do I need to take the update at all. I'm looking to flash the latest Viper rom and just wanted to check before I do. Sorry if this question was ask before.

When your target is to flash a custom ROM based on 4.4.3; you don't really need all those going back to stock and apply OTA stuff
What you need is flash the 4.4.3 firmware of device version then install ROM ... that's all

First make sure you do have the developer M8 as I find many said the same thing but in actual fact they are not.
If yes ... I have the untouched 2.22.1540.4_firmware.zip here : http://sourceforge.net/projects/htconem8/files/2.22.1540.4_firmware.zip/download
then follow either this guide : http://forum.xda-developers.com/htc-one-m8/general/vomerguides-m8-bootldr-unlock-s-off-t2800727
or this guide : http://forum.xda-developers.com/htc-one-m8/development/firmware-flashing-panic-attacks-t2824048
on how to flash the firmware zip
As the firmware is untouched, it will restore the stock recovery to your device.
So after successfully flashed the firmware, you should flash the custom recovery of your choice again in order to flash the intended custom ROM.

I'm gathering from the OP's location and past devices, that AT&T is the carrier.
If so, I would recommend flashing the 2.23.502.3 posted here: http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-t2837365
This contains the latest AT&T firmware (including newest AT&T radio). Then flash whatever 4.4.3 custom ROM you want.
On the 2.22.1540 firmware, I was getting some random data drops on AT&T. After flashing the 2.23.502 firmware, everything is working perfectly for me.
EDIT: My bad, I somehow completely missed the critical point that the OP has the Dev Edition. ckpv5 is correct for the Dev Edition, 1540 firmware is what you want (the firmware released with the latest Dev Edition OTA).

That's why I said that he need to confirm whether he really has developer edition M8.
If it is At&T .. I will not recommend the Dev Edition firmware (in fact I will not get involve as I don't know much about At&T device)

Appreciated your help here. I can confirm the phone came with a unlock bootloader and my CID number is BS_US002. Does this mean I got the developer version of the M8?
If so, do I just follow the guide you post above, and do I need to change my CID to the super 11111111?

BS_US002 is Dev Ed.
There is no need to change to SuperCID when flashing the firmware meant for your device version; no CID and MID change is needed.

This part below, my phone freezes on the HTC logo. Do I repeat the entire step from beginning when it freezes or that specific command it freezes on? See below.
fastboot oem rebootRUU
Note: if this command freezes, just disconnect the USB cable and hold the power and volume down buttons until the device reboots.
Then, repeat the steps above again.

Major thanks to you sir. I use the second guide you provide above after multiple fail with adb and all seems to be working fine. So if I understand you correctly, as long as I flash the latest firmware which I now have and regain recovery, there is no need to take the OTA from HTC to move from 4.4.2 to 4.4.3? So I can now flash roms base on 4.4.3 like Viper?

Yes...now you can flash 4.4.3 Sense based ROM like viper.
If you ever need the stock ROM, just follow the Stock Backup link in my sig.

[Q] Unroot S-On HTC One M8

I planned on converting my One M8 to a GPE edition but I couldn't gain S-Off, so now I have a phone with root access and TWPR installed. In preparation for HTCs upcoming Lollipop OTA, I would Like to bring my device back to full stock so I can install the OTA. I can't seem to find a way to do this without having S-Off. Could someone help me please?
Thanks, Nathan

sakitech didn't mention anything about losing root or relock bootloader requirements to receive OTA updates after following his video.

Oh, sorry for not being clear xD
No, I don't think you will lose root and you don't have to relock bootloader afaik.
Even so.. you can always redo the process of rooting and unlock the bootloader after OTA update.. no biggie
but if you run stock rom and recovery.. it shouldnt affect root or if ure unlocked with OTA updates

I just reverted back to stock last night with s-on. you will have to relock your bootloader (I used a tool kit, but had to boot into the bootloader myself to get the toolkit relock it) and flash a stock RUU (exe or zip). I suggest using an exe to flash if available. I have a sprint HK edition so I used an RUU exe for that model, and all worked perfectly. I was able to install the OTA update they just released with no problem after I was back to stock.
sakitech's method should work too if you want to try and keep root and the bootloader unlocked

[Q] back to stock

Yes i read threads over going back to stock but my question is a little bit different
I got a dutch T-mobile branded M8 after i did my first root i made a a backup from my phone with TWRP.
i can't get S-OFF, so my phone is still S-ON!
Now i got the problem that my HBOOT isn't updated since, this is giving me problems with newer versions of TWRP and so for CM12.
My thoughts were:
- flash my backup to my phone
- ? 1
- ? 2
- update it regulary via ota updates (guess my phone is updated to the latest hboot)
- Root my phone
- install any new rom
Frist my questons are for the questionmarks in my steps:
? 1: Should i un-root and relock my bootloader?
? 2: Anythinge else i missed?
Thanks in advance

You can't s-off, since sunshine says your phone is not supported? Or you don't want to pay for sunshine?

1) No need to unroot or relock bootloader. But no system files can be modified in order to OTA. If you made the nandroid right after installing TWRP and root, without any other mods, you should be OK.
2) You also need to flash stock recovery to install OTA

Don't want to pay for sunshine, don't see the importance, just want to **** around with custom roms, never has been a great difference for me.

If you want s-off, pay for it. Otherwise, don't. And I agree that if the goal is merely to update firmware, you don't need s-off in your case. As for the importance, s-off allows a number of things, including being able to flash radios, modified hboots, and unlock SIM. These may not be relevant or needed by you.
But to say you can't s-off is not correct. You just don't want to. When asking for help, its best to provide the most complete and correct information.

The only way to S-OFF is to use SunShine @ http://theroot.ninja which will cost $25 respectively.

Its not clear to me why you want s-off.
You only need stock ROM (no system files altered by root) and stock recovery to OTA. Relocking bootloader is not necessary. Its only necessary to relock bootloader to RUU (when s-on).

firewater was an online service. So it no longer works now that the developer stopped supporting it 3 months ago.
But I'm still not convinced you even need s-off. You haven't provided a valid reason that required s-off.
If you do need soff, you need to use sunshine. There is no other option to s-off.

The S-OFF it's more save to get back to locked on boot loader and with that you can get OTA UPDATE from HTC what I hope is to try flash viperM8 Rom and try it and then try sky Rom and see if I don't like them can back to stack with S-OFF
maybe I am wrong I don't know if

As I already stated above, you do not need to lock the bootloader to OTA update, and you do not need s-off to OTA update. OTA update works fine with bootloader unlocked or otherwise.
You also do not need s-off to go back to stock. Just made a nandroid (or get one from the nandroid collection here) to restore stock ROM, and restore stock recovery (also in the collection).
With s-off you can make the bootloader say LOCKED instead of RELOCKED. But warranty service is typically the only time that is desired.
Yes, s-off will give you more recovery options. Such as being able to run RUU for any CID, or "downgrade" by RUU. And it lets you do things like flash radios or modified hboots. But of the things you mentioned, its not needed.

Hi @redpoint73 can i ask you a question ?
I bought a second hand M8 and it already had S-OFF via sunshine.When i entered bootloader it says : Software status : Modified , (bootloader) UNLOCKED and S-OFF.
I asked the seller for the "unlock_code.bin" and he said that didn't have any.He said he simply ran sunshine to S-OFF.Didn't modified further.No custom recovery no root (although sunshine temp roots) no custom ROM.
So my question is this : performing S-OFF via sunshine will auto unlock your bootloader and say Software status : Modified ?

I actually did s-off back when firewater was still working, before sunshine even existed. So I can't speak from personal experience, just what I've read on these forums. I believe that the sunshine app gives you the options to temp root, s-off, and unlock the bootloader (by means that bypasses HTCDev.com). So that is probably what the previous owner did.
With s-off there isn't ever a need to relock the bootloader, and therefore no need to unlock it again with the bin code. RUUs will run with bootloader unlocked when s-off. And you can change the hboot flag to LOCKED for warranty purposes with s-off.
If for some reason you want to relock and then unlock the bootloader again, you can just go through the HTCDev.com process to get a new bin code. But its not advised. As I don't see why you would ever want to relock (for the reasons just given). And once you go through HTCDev.com, HTC will have a record of you doing so (which they do not at this time).

Thanks you have been more than helpfull!
Another question and last one :
Can i dual boot with multirom a sense 6 rom and the GPe rom?
I have the latest firmware installed so from what i read GPe roms can run without any issues.

No idea, I've never used MultiROM, and not that familiar with it. Hopefully, someone who knows will chime in. Or you can post to the MultiROM thread to possibly get a quicker answer.

T-mobile Firmware issue help required

i have a t-mobile version of htc one m8 but when flashing ROMs , i flash international version of the ROM which i'm flashing. The phone is sim-unlocked.
Lately i'm having problem of my phone getting stuck on boot and only way out is wipe cache and dalvik on every time i reboot. And also GPS is not working (tried every fix but no avail) I'm guessing his is some firmware problem.
So the thing is I want to get back to Android 4.4.4 version ( on which it was earlier before i flashed any Lollipop rom , so that i could flash T-mobile's OTA to Lollipop back ( for firmware update ) and after reading and some research , i have understood that i have to be stock recovery and relock the bootloader and get T-mobile RUU ( very confused about RUU thing)
Could someone confirm if this is the correct procedure and explain what steps i need to follow IN ORDER to get this done ( and if links to corresponding guides i will be really helpful) .
I AM S-ON.
Hboot - 3.19
Radio - 1.22.213311491.08G
Please help , really frustrated by these issues and apparently previous threads of mine have gone unanswered.

Unfortunately, if you want to revert to KK (or any older version), you will have to be S-off to do so. So, pay the $25, get S-off (which will helpfully unlock your bootloader at the same time), run T-Mobile RUU for desired version.
However, even if you are S-on, you should be able to use a current or newer RUU to get the firmware up to date, then move on to installing the ROM of your choice. You are probably better off going to the latest firmware and running an alternate ROM, but that's just me.

So if i were to follow S-on steps , i will have to first flash stock recovery , relock bootloader and run t-mobile RUU for firmware upgrade ?
When i relock bootloader everything will be wiped , right ?
So i connect my phone to pc with relocked bootloader and stock recovery and run t-mobile latest RUU on windows ?
Is this the correct procedure?

That is all true; except you do not need to install stock recovery to RUU.
Stock recovery is only needed to OTA, not for RUU.
