Sorry for creating a lot of help threads, but things just don't wanna work my way.
Yesterday I wanted to flash a RUU to see exactly how HTC does things and if it's easy or hard. Anyway. I come from a Galaxy S3 and if I wanted to go back to stock from any other rom, I simply flashed a stock rom tar with a program called Odin, but it doesn't seem to be as simple with HTC.
I downloaded a RUU for the Europe region as it seemed the most obvious thing to do, but my CID is Nordic (HTC__Y13). Here's how it went:
Being on a 4.2.2 custom rom:
I tried running the RUU when I was on a 4.2.2. custom rom (InsertCoin 2.0.2), and I fired up the RUU file and followed the instructions. Then it said my phone isn't supported and that I need another RUU file.
Being on a stock odexed 1.29 rom:
I then installed a stock 1.29 rom from Mike1986. and then fired up the RUU. I followed the instructions and it seems the flashing started. It sent me to the RUU mode (the HTC screen) and began the flashing process. It said it wiped the data and that it sent some signature keys, I think. Three minutes later, the RUU window disappeared. I could see the program was still running but the window disappeared. It quickly flashed for about half a second and I could see some text saying that my phone isn't supported, but why the hell did it commence the flashing?
I pulled the cable, long-pressed the power button and let it boot, it hadn't wiped a thing.
Let it be known that before I opened the RUU's, I made sure I was bootloader locked and S-ON (with the revone method).
Is it because I have the Nordic CID and I had a RUU for the European region? If so, I looked anywhere and everywhere for a Nordic RUU but there's none to be found.
Any help is appreciated.
You can only use an RUU which is the same or newer than the firmware on the phone, e.g. if your last official update was 1.29.401.13 you could only use an RUU that version or above UNLESS you're S-OFF, in which case you can use an older one if you have Super CID and a locked/relocked bootloader

So what you're saying, is:
If I acquire Super CID, then flash a Europe RUU and then set my CID back to what it originally was (or maybe even set it to HTC__001) and then reflash the RUU, and it'll work beautifully? I'm S-OFF, btw.

Where you S-Off or S-On when you ran the RUU?

S-ON with the bootloader locked. I wanted to see if it was possible.
I'm not really looking to revert to unrooted stock, at least not now. I just want to know that it's possible without too much work for when it would be necessary or when I want to try out unrooted stock again. It's always nice to have a fallback.

As far as I'm aware, you can only run a RUU that is relevant to you device whilst you are s-on and only one that is equal to or above the firmware that you are running.
The only way to return to official un-rooted stock is, again, to run a RUU for your device or install a completely stock nandroid backup of your device or one running the same version as yours.
OK, full example...
You originally get an unbranded One from the EU and you get the OTA to 1.29.401.13. From this point on, with an S-ON/Locked phone with CID HTC__001 you can ONLY flash an RUU which is 1.29.401.13 or higher. This will never change. If you get an RUU from a specific carrier you cannot flash it as it doesn't match your CID.
If you unlock the bootloader, but stay S-ON, you cannot flash an RUU at all - you HAVE to relock the bootloader first but you can still only flash an RUU matching your CID and is the same or newer than your current version.
If you S-OFF and change the CID to 11111111 you can flash ANY RUU you want, even those older than your current version, e.g. 1.28.401.7. You still have to have a locked/relocked bootloader but you can stay S-OFF and flash the RUU. As the only RUU available at the moment for the unbranded One is 1.28.401.7 it means you can flash that and then get the OTA updates in sequence to get to the latest version
Once back at the older version using the RUU you could change your CID back to HTC__001 if you wanted but I don't think it matters

Ah, thanks for the clarification! If I do this (Super CID plus flash the RUU), should I change back to the HTC__Y13 cid or change to something like HTC__001 to get the updates for the Europe region? I heard Europe gets OTA's faster than other regions.
One more thing, why does the bootloader have to be locked? Does the RUU check for this?

If you wish to get ota's you will need to have a cid which is relevant to the RUU you have run. Either of those cid's should work for a x.xx.401.x RUU. Not sure about the bootloader locking for an RUU.

The bootloader doesn't need to be locked to flash a RUU. A guy over at Swedroid flashed a Europe RUU (401 device) (after setting Super CID) coming from a carrier-branded One and the RUU did flash perfectly.
I would of course want OTA's, but the thing is, I heard Europe gets them faster than the Nordic region.

Not necessarily. As with the s3, releases seem pretty random from country to country in Europe. I had the one x with HTC__001 cid and was one of the last to be updated.
Sent from my Nexus 7 using xda premium
Locked the bootloader and went into fastboot and started the RUU. It is now flashing :victory:
After it's done, I will turn the CID back to HTC__Y13 and reflash the RUU.

I, personally, would relock the bootloader purely to cover yourself. As for CID, it's up to you. Using HTC__001 might not get it the second an OTA comes out but I'm sure you're patient enough to wait a few days

I just want back to stock for a few days. I'm a bit tired of custom roming yet I can't stay away from it!

I've done the same with my Nexus 4, and shall do the same with my One when I get it next month. I want S-OFF purely because the only RUU we have is an older than what I'll likely get on my phone. This way I can always go back to stock (unless a newer RUU leaks that is!)
How awfully peculiar, though. After I flashed to stock (the 1.28 something RUU), I got an update to 1.29.401.12. My brother, whom also have a One in the same region as I, has the 1.29.401.16 update (I am four decimals behind him ).
I thought I would get an update to .16, or am I just being too impatient?
I know I had .16 before custom roms though.
I read all, very useful conversation,saved me lot of time
Only a thing i havent understand
Im now S-OFF,unlocked with superCID ( runnind a branded italian rom with (now old)TIM__041(if i rememeber right)cid)
What i need to do to have a stock unbranded european RUU
Do i need to relock bootloader Before flashing or not matters?

Hello guys, I tried the new GPE 4.4 rom flashing the RUU, and I am pretty disappointed on this update...so I decided to return back to sense...
1) A 4.3 sense 5.5 RUU zip would be great, I searched for it but I can't find nothing, anyone?
2) OR...what if I flash a sense rom on top of the 3.58 GPE firmware? is this correct to do? have I got to flash the radio?
3) OR, again...if there is no RUU and I can't flash a sense rom with radio on KK fw, I think I have to flash 3.62 fw with radio and a rom...no?
I like clean things, because of this I ask for a RUU, is better wipe everything and clean flash...all in one and ready to go...thanks in advance!
Cheers

The firmware and radio is mainly for stability issues and some optimizations. if your device is s-OFF you can flash new roms doesn't matter if they are sense 5.5 or aosp or gpe editions. If you want to return back to 3.64 fw hboot 1.55 you can find that in the RUU mega thread in the HTC One Android sticky section. when flashing the RUU make sure you have super CID or flash the correct versions or else it will not let you force flash it.
If you convert to Developer Edition (3.22.1540.1), you will have 4.3 and Sense 5, but 4.4 with Sense 5.5 will be released as an OTA update in a few days. I'm sure OP knows better than to use superCID. It will prevent you from receiving OTA updates. Always use the proper CID for the firmware you're using (unless it's a custom ROM or something that you wouldn't want to do an OTA on). If you convert to the International version (3.62.401.1), you will have 4.3 with Sense 5.5, but be waiting until January for the Android 4.4 update. There's no real difference between the two. They're both world-wide variants, but the Developer Edition gets updated well before any others.
For Dev Edition, change CID to BS_US001
For International, change CID to HTC__001
For Dev Edition, MID must be PN712000
For International, MID must be PN710000
To flash from GPE, you may need to downgrade your Bootloader first. It was a nightmare for me getting off of GPE until I figured that part out. I assume you're already S-Off. Sneakyghost provided 1.44 bootloader can be downloaded here http://d-h.st/qfc
My Htc One is S-OFF with super cid "11111111" hboot 1.44 and latest radio.
the original cid was TIM_401 something from Italy which I didn't found the RUU over the internet for it, so from day 1 using custom roms (viper one)
Actually I was a iPhoner for many years just few months ago upgraded to "android" so I am pretty new in all this.
I wonder if it possible for example to flash the us developer edition RUU which receive very quickly OTA updates from HTC on my HTC one? and covert my phone to full developer edition?
and another question if I flash the stock rom using fastboot this will upgrade my HBOOT/Radio too?
Sorry for my newb question

s-off you can flash any decrypted RUU.zip by simple edit of the android-info.txt to match your phone (use fastboot getvar all)
Rom will not update firmware (hboot/radio) - RUU will

first flash this firmware
http://www.htc1guru.com/dld/3-22-1540-1_firmware-zip/
change your CID to: BS_US001
Then you can use this guru reset to change to a developer edition ->> http://www.htc1guru.com/dld/guru_reset_m7_3-22-1540-1-zip/
Choose to flash stock recovery and no root and you'll have a stock developer edition One.
I don't think you need it but if you do
download Guru Bootloader Reset from here: http://www.htc1guru.com/dld/guru_boo...reset_1-0-zip/

Hi all.
Last week, after i soft bricked my phone (HTC ONE M7 EU with no carrier , bough directly from ) trying to update it to the latest version (i had mine unlocked and rooted to solve previous battery problems), i finally fixed it with the help of an user of this community
I have now an S-off HTC One GPE with 4.4.4 (via OTA update after flashing a RUU zip)
I kinda not like GPE and i think i should back to Sense .
Can anyone point me to the correct RUU thread and/or instructions or presequisites i shoult take account to do this process?
Thanks in advance

considering you are s-off,
very little, but even with s-off, you will first need to downgrade hboot to same or lower version than the signed ruu.exe/ruu.zip
on the other hand, a decrypted ruu.zip doesn't have that restriction

So my process will be...
1. Downgrade hboot to 1.44
2. Change back my cid to HTC__002 (when i flashed the RUU from the GPE i changed it to GOOGL001)
3. Flash the RUU zip
Is that right?

you don't have to go back to hboot 1.44
If your RUU is 4.xx flash a 3.xx firmware first
or 3.xx RUU a 3.xx or 2.xx firmware will work.
you may also need the MID change tool if you changed it also

The 1.28.401.7 is Jelly Bean it's equal to a 3.xx.xxx.x RUU
So the Firmware you would want is this http://xda7.androidrevolution.org/db_mirror/Firmware/HTC/HTC_One/401/2.24.401.8.zip
Anyone know where I can find a stock Lollipop Sense ruu that I can flash to restore an M7 back to stock?
Previously I have been using a euro JB based ruu from htc1guru, but it's a pain starting out on Jellybean, and upgrading from there but that website only goes up to a Kitkat radio for a euro base ruu, and even then I ran into issue flashing kitkat ruu.
I am super CID and s-off of course. I always flash 1.44 hboot prior to doing the above.
I need the zip by the way, not an exe as I am running linux on my laptop.
Thanks.

HI bob, look at the sticky threads in the general section. Don't forget that you need at least hboot 1.57 and a 6.xx.xxx.x firmware (version-main) to flash a Lollipop RUU.
