[Q] Questions on rooting, recovery and ROM's (ex-Samsung user)

OK. I'm a little bit lost in the HTC world!
I've had a Samsung Galaxy Note II for the last year and have just replaced it with the HTC ONE (M8). I found the whole rooting and ROM procedure relatively straight forward with the Note II. In a nutshell you:
1) Rooted with a Windows based application
2) Installed / Flashed a recovery system
3) Flashed a custom ROM using a Windows based application called ODIN
And that was that. Pretty straightforward. Having had a nose around the HTC forum it's awash with clever folk using abbreviations and acronyms like CID, RUU and S-OFF...!
My M8 is on EE network in the UK which I know is CID ORANG001. What I would like though is to convert my M8 to a generic European M8 so I can receive the latest HTC updates rather then await EE to push out their version. This therefore prompts me to ask the following questions:
1) Is this something we will be able to achieve?
2) What is the (potential) process to achieve this (assuming something similar for the M7 already exists)?
2) Will over the air updates work?
I've read numerous posts which seem contradicting. Some talk about a simple change of the CID others mention S-OFF as the GOD of everything related to the subject. If I were to guess, changing the CID seems too simple, but I'm guessing once changed to a generic EU CID it's possible to receive HTC's OTA updates? Or am I wrong there? Or having another guess I would assume I'd need to go down the lines similar to Samsung process of rooting or S-OFF (security off?) and flashing a generic stock EU ROM?
So what CAN currently be achieved and what CAN'T currently be achieved?
I guess I could do with a little background on these processes and the terminology used.
Any help, greatly appreciated.

Can :
Unlock the bootloader and flash a custom recovery to install a custom rom based on the latest firmware. You are depending on rom updates from the dev if he updates it to the latest software/firmware
Can't :
S-off
Change cid
Get ota via another rom
Run a ruu because they are simply not available
So to receive ota you need your original stock rom. And before you start messing around please make a stock nandroid backup and store it !

Also not familiar anymore with HTC. After reading and reading and still not finding the exact answers to my questions, so I simply (after unlocking and flash TWRP recovery and backing up) tried to flash Virtuous ROM (1.54.401.5) over my German o2 device (1.12.206.17, CID O2___001). Everything worked except WiFi, so I tried a last call with mikes ARHD Rom 3.1, before going back to stock. And this ROM works brilliantly!
But I would also be happy if the OP questions could be answered...
@Mr Hofs
1. the WiFi problem discribed above could be firmware related?
2. When my Provider o2 brings out an update with firmware, can I simply relock bootloader and push the (perhaps) available firmware.zip it to the device via fastboot like mike explains in his firmware thread?

Edit :
Well that would be weird as both roms the OP flashed are based on 1.54.401 so i would say no.....

OK thanks. Few more questions if I may.
So from the "can't" list, IF we can get the ability to change CID and have S-OFF in the future, would it provide the ability to receive OTA updates when HTC push them out, or are OTA updates simply out of the game entirely?

Yes that should be possible , all you need then is
Changed cid
Stock rom
Stock kernel
Stock recovery
Or the ruu (if available)
Then the phone is ready for ota updates.

Great thanks. Last question then, what is RUU?
I'll keep your thread bookmarked and attempt to get a backup in there.

A ruu is a Rom Update Utility and it contains the rom, kernel, firmware, recovery (and some more stuff). When a ruu is installed its like the phone is factory stock.

[Q] How to revert CID and original RUU on M8w?

I bought an M8w in Beijing for my friend. The phone is now rooted, S-OFF'ed, Super CID and on ARHD. After flashing the ARHD ROM, it started to have some problems with the screen as you can see from the photos attached. I'm in Turkey and since M8w is not sold in Turkey, HTC doesn't give technical support -what a shame!. They asked us to flash the original ROM to be able to help us and somehow they are sure that the problem is ROM related!
So we have to revert CID, relock, S-ON and revert to stock ROM. ): Unfortunately we didn't get any backups or screenshots of the recovery/boot screen.
Where should I start?

No answer yet?

do you kno your old CID and rom version?
if not, opps, guess you will have to guess, there are threads on how to change your CID and stock roms links, take your pick which you feel is best.

Changing ROM and FW to go to WWE vs Dev

Hey everyone,
I first want to say thanks for all the instructions here on this one, it's been a lot of searching, but got through getting my phone boot unlocked, TWRP installed, rooted, and finally through Venom, S-OFF.
I bought an M9 from eGlobal Central which landed me a HK phone and Asia ROM. It's also meant that with the subsequent upgrade to the 1.4 firmware package the battery has gone from terrible to paper weight.
I've got Venom on there for the moment (That got me through Sunshine) and I'm looking either at a stock Dev edition or WWE ROM (To get up to a >2.8 firmware), however, I'm wondering where to go now in regards to WWE or Dev. Errr... OK, just correct me where I'm wrong here:
I'll need a firmware package that matches the ROM.
I'm guessing I'll need a complete RUU, but for European Dev perhaps? What's the CID for that?
Actually is there any difference at all in the radio software between the different firmware releases and capabilities?
What is the current Android version in WWE that's available? (And what firmware more to the point, I just want off 1.4)
I've seen Dev is now on Android 5.1 and 2.8 firmware (And I'm guessing this has been patched higher again)
I assume that Dev has a faster release schedule than WWE?
I basically want to get myself back to the point where I'm getting OTA updates, but my phone lasts a day instead of a couple of hours (I should've bought another M8).
I'm sure that this has been done before, but hours of Google searches has left me well, slightly less in the dark, but the light at the end of the tunnel could be an oncoming train, so, thought I'd just ask.
Thanks for all your help,
Berny

You're s-off so just go supercid and you can flash the latest 2.10 firmware. Forget OTAs because you can't get them unless you're 100% stock, and the back and forth required to do it is far more trouble than its worth IMO.
Can't speak for everyone but battery life on 2.x has been fine.

Not able to get back to stock (One M8S)

Hi there,
This is my first thread here, so sorry if anything in this post is not correctly.
I got the following problem: I installed CM12.1 on my HTC One M8S (M8_QL_UL) but now i want to go back to stock. I bought the phone at Amazon (Germany) and it was sold as unbranded.
However when I tried to flash the stock firmware (from http://forum.xda-developers.com/htc-one-m8/one-m8s-general/make-custom-recovery-htc-one-m8s-t3114245) over Hboot it told me "wrong CID" and Large Image Fail.
Then I got myself the phone's CID and it came out that it was not the HTC Europe Version (I tried to install the Europe build with Android MM as I had that one before) but the T-Mobile-DE version.
So the problem is, that there is a firmware for the T-Mobile-DE one, but it is still Sense 6 with Lollipop and so I am not able to install that, since I already have had MM with sense 7 on that phone before.
Now I cannot find a MM build for the T-Mobile CID online.
Beside of that I created a Backup with TWRP before flashing CM12.1 but now TWRP does not recocnize that backup.
If possible I would prefer to install the Stock Rom "clean" because my backed up one was very buggy anyway.
So my question is, how can I get back to Stock? Is there any proper build to download? If not, is it possible to get S-Off for that phone, to change CID? Sunshine does not appear to be working for the M8S...
And if nothing like this works, how can I access my backup with TWRP?
Thank you so much, hopefully anyone could help me!
Cheers, Fietipaldi

Im in the same situation but for Vodafone. We need some updated RUUs on the site

Help to return to stock RUU

Hi,
I'm totally new to this and I'm looking for help.
I have a HTC One (M9), unlocked. I realised since I got the handset (insurance replacement in 2016) I've never had an OTA update. I contacted HTC support who advised that I am running unofficial software and that is why I cannot get OTA updates. I've asked them to elaborate on what is "unofficial" about it as I have never rooted the handset or messed around in any way. They couldn't elaborate and advised I should send it to them to be flashed (at cost, as it's out of warranty).
Anyway, I want to put my handset into a condition where I can receive OTA updates & also ensure that I benefit from the latest software updates so I started looking into how I could do this. As a noob to Android the easiest method seemed to be via RUU exe. I've downloaded 2 different RUU's from HTC website but both errored with "incorrect version" when I tried to install. I then downloaded a ZIP which I followed the instructions to boot to recovery & install from phone storage, this also errored with "cannot find files".
As above I've tried going from Android v5 to v7 and that failed, I don't know whether I had the wrong RUU or I need to upgrade to v6 first.
I'm in the UK with I presume a UK handset but the RUUs were downloaded from htc.com not htc.com/uk as the UK one doesn't seem to provide this.
So long story short I'm looking for help getting the correct RUU for my handset and I'm having no luck. I'd appreciate any advice given.
HTC One M9
CID: HTC_001 (WWE)
Android: 5.0.2
HTC Sense: 7.0
SW: 1.32.401.17
S-ON
Cheers

Firmware 1.32.401.17 only got distributed in one single country (I always forget which one it was - it definitely wasn't the UK). Therefore, the combination of that version together with the HTC__001 CID can only get achieved by tinkering with the phone.
You're actually using an official stock rom but you can't update your phone since the UK never was meant to receive this specific version and/or its OTAs.
You should be able to "return" to 1.32.401.15 without much hassle by following one of the guides in the ReadMe thread. Even with S-ON this little downgrade should be possible (c.f. the RUU section of the ReadMe thread).
If flashing the 1.32.401.15 RUU fails you'll have no choice but unlocking the bootloader, getting root, setting the phone S-OFF and retrying to flash the RUU. All needed steps are explained in the ReadMe thread, as well.

Hi Flippy498,
Thanks very much for the response and advise.
I've no idea how it ended up like that. I can only assume as it was an insurance replacement that it was initially branded then flashed incorrectly before it was issued to me.
I'll try your suggestions over the weekend.
Thanks again for the knowledge, its appreciated.
Cheers
Breezo

Hi Flippy498,
That worked perfectly thanks very much for your help. Took the software down from .17 to .15 and OTA updates kicked in immediately.
Now running on Android 7.0
Cheers again

Deffo not a UK phone. We went from 5.0.1 out of the box straight to 6.0.

I'm pretty sure that UK received Android 5.1, as well. No variant of the M9 skipped firmware 2.x.
Firmware 1.x = Android 5.0.2
Firmware 2.x = Android 5.1
Firmware 3.x = Android 6.0
Firmware 4.x = Android 7.0
Since the UK M9 is the "normal" European unbranded version (SKU 401) it received the following versions:
1.32.401.8
1.32.401.15
1.40.401.8
2.10.401.1
2.10.401.180*
3.35.401.12
3.35.401.32
4.14.401.7
4.28.401.3
In addition to that there are:
1.32.401.6 (a pre-release firmware shown on the MWC)
1.32.401.17 (which got distributed in only one country)
* Normally the three numbers behind the last dot indicate a beta firmware. Since the Nougat update couldn't be applied in one single update they had to distribute this version, as well.
