Stock ROM & Changing RUU

Hi,
I purchased a new HTC One X from France (I have a friend there), and it came in french and with some apps of SFR (a french cellular company).
I want an official ROM of HTC but without all those apps, and with Hebrew support.
I saw this page with stock ROMs, but how do I know which one is suitable for me?
And can I install a stock ROM that did not come originally with my phone?
I am new to Android and smartphones in general, so please be patient with me (I'm a quick learner though).
Thank you.

Download cidgetter from the play store, that app will let you know your cid. My hox is unbranded with cid 401.
When you know your cid go to the page with the ruus and look for one with your cid in the version number.
Remember though you can only use a ruu with same or higher version number
You can't change region or carrier unless you have an s-off hox

OK, my CID is VODAP203. What does it mean?
And what is s-off hox, and how do I get that?
(Simply, all I want to do is to reset my phone to factory's settings but like a not-branded one and with Hebrew support, as if I bought the phone from my country).
Thanks in advance.
ps: is there any detailed guide which explain all those terms and how to install a new ROM and all this stuff...?

Tell them your cid and some 1 should be able to guide you to the relevent ruu for your cid, that will get you back to stock factory settings.
You can't change cid unless you are lucky enough to have a s-off hox (s-off = security-off) so your best bet if your not bothered about warranty is flashing a custom Rom with all the bloat removed.
Go to this thread for all you need to know about flashing a custom rom

You can only use RUUs from Vodafone France - you can't use a stock ROM unless you go custom

That will get me back to factory settings but it will be exactly like I have it now (mine is brand new), right?
I don't want it like I got it, I want it as if it wasn't branded (like another region).

I don't understand something, I can't use a stock RUU but a custom one I can??
What do I need to do to get an official ROM (General, not branded, like pure HTC official ROM)?
Thanks...

You can't until we gain s-off, that's why if you want rid of all the bloat ware on your phone you will have to go custom rom or root and uninstall the bloatware yourself

I'm going to assume the lest complicated situation, you have a regular HTC One X that is S-ON, but that you've managed to unlock your bootloader and root your phone. From browsing around it seems like the most standard starting point.
I think you are right; it's a little weird that you can only use the RUU (what HTC provides as a stock / factory ROM) from where the phone was intended to be used. I guess this makes some sense: you can manufacture custom configurations of the phone per clients markets (i.e. US Telcos may want two types, a delux version and a stripped down cheaper version) so HTC makes sure to configure the phones differently. If you have different phones, then you need to ensure each works as it should out of the box, so two different ROMs might be required where each stock ROM is optimized for use with the phone configuration as dictated by the CID (does CID - configuration identifier??). So for most of us, the RUU that's available to us is strictly determined by the phone CID.
So why not create a super RUU that is so awesome that it could determine what the physical and software configuration of the phone is and permit only the compatible features? Are HTC developers too lazy?? Maybe, I don't know, I'm not a developer. So enter the custom ROM. A kind of super RUU IMHO that allows for more customization based on the talents of the developer(s) who often design these things for free, on their own time, and although not obligated one bit to support or update them, do so anyway.
So there you have it, you are stuck with the RUU that is compatible only with your CID, or you can research the various custom ROMs that exist and try them out.
Good luck and have fun with it.

[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.
Sent from my HTC One_M8 using Tapatalk

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] HTc One M8t (China) root and HTC Sense original?

Hi XDA
Im lost! I bought the HTC One M8t in China today, in a real store, so its not a fake. Im on vacation in China and come from Denmark.
I belived it would just be plug'n'play with this phone, but since its bought in china there is a lot of chinese apps and no Play store
I asked around and i realised i will have to root the phone. Im a totel rookie and i have never done it before, so i hope you guys can lead me in the right direction.
Questions:
1. How do i root my HTC One M8t?
2. Can i get the original HTC Sense from my region (Denmark/Europe) on my phone?
2.1 If yes, how do i do that?
2.2 If no, can i get Android L on my phone?
I really hope someone can help me, i am totally lost and really frustrated since i thought it would be an easy task to get it up and running.
//Crime

Help is here...kind of
Hey CrimeRider93.
I've been reading up on this topic because I've just landed myself in the same situation.
So, I managed to root my M8t but I haven't managed to flash another ROM (like your Danish one) to it yet. The reason for this is because I can't get rid of the S-ON on the phone which stops you from installing custom ROMs. To my knowledge, although I'm still searching, there isn't a way yet.
The slightly good news is that you can put a ROM that was designed specifically for the M8t on it but I haven't managed to find one with Google Play etc. yet.
So in conclusion, you can root your phone but you can't put anything useful on it yet (that I know of).
I hope I've cleared things up a little and if you'd like an explanation on how to root the M8t I'd be happy to tell you, just let me know. :good:

If you already managed to root (meaning you obtained bootloader unlock and custom recovery) you could try to s-off with firewater. If firewater doesn't work for your M8 you can try sunshine s-off, as I did.

To obtain root you have to unlock bootloader (e.g. via htcdev.com) and install a custom recover (my personal choice was TWRP). After this you can flash root with your "new" recovery.
After this you have to s-off your device (see my answer above).
If you ar finally s-off you can download a stock HTC backup of the European (WWE) ROM as well as the fitting firmware.
Next step would be to perform a TWRP backup of your device and place the above mentioned ROM backup in your TWRP/Backup/H..../ folder on your HTC One M8 and rebooting back into recovery.
In recovery you can now backup to your dowloaded stock ROM and again reboot to bootloader.
The last two steps are to change the CID to a European (WWE) one (e.g. HTC__102) and after this flashing the firmware in RUU mode.
For a more detailed guide just search on this forums, or simply ask your questions. I'll try to help as good as passible. Remenber I'm not to blame for a brick of your smartphones, should something go wrong during one of the steps.

That doesn't work for the M8t

Recovery - You need a special custom recovery for the M8t, I used this one:
http :// bbs. anzhi. com/ thread-8936202-1-1.htmlRemove the spaces, I'm a new member
S-OFF - That method works for most version of the M8 but not he M8t, (though I didn't try sunshine).
I've managed to get Google play using Soul 2.0 which was made especiall for the M8t

For the M8t, there is a easier way for Google Play service (gmail, map... etc),
Just search "GMS安装器" from HTC App store or Baidu App store. Then you are good to go.
As for the ROM, yeah... I am hoping to find some idiot step-by-step tutorial to teach me how to do so. Wonder if any kernal or recovery or rom on the forum can be used on HTC One M8t? Also the phone is using TD-SCDMA and TDD-LTE, are those firmware or rom designed specifically for the hardware of FDD-LTE and WCDMA?

[Q] I got the indian m8, Am i limited to anything in regards to flashing?

Hi, I bought an unlocked htc one m8 but i recieved the indian version (m8q) and I'm not from india, Everything works fine and I called htc and they told me that I shouldn't have a problem since the indian verison comes with international warrenty.
The only thing I'm worried about here is compatibility with the stuff here on xda, will i be able to flash roms without probelms and will i be able to convert it to a gpe device if i wanted to.
The Cid is HTC__038, the model id is 0P6B65000 the software version i have currently is 1.56.720.6 and the product name (from the getvar all command) is m8_ul. Is the hardware incompatible with roms made for the international gsm version (with the sku 401) or can i just change the cid/mid or make it supercid to use it with any of the guides hosted here.
I havent been able to find anything so i would really appreciate any help.

I own the same device and to be true, the Indian Variant lacks support for all Sense based ROMs as they are based on different model with different CID and MID number. Custom ROMs work fine.
If you are very proficient with flashing stuff in HTC devices then you can use firewater to S-OFF on 4.4.2 . Ver. 4.4.3 has patched some vulnerabilities that do not allow firewater S-OFF to work nor the sunshine one.
I had already updated to 4.4.3 due to which now it's currently impossible for me to obtain S-OFF.
Also Indian Variants have yet not received the latest updates i.e. 4.4.4

Thanks for the reply, but are you saying that If i can acheive s-off and change the cid and mid will that make the device compatible with the roms or will flashing them brick my device? Also, do you have any idea about compatibilty with gpe based roms?

This is my first HTC device and the first expensive one that I bought so I am being really cautious about tampering my phone.
Yes, if you achieve S-OFF, then you can change your CID. Don't know about MID (I have yet to know more about it). Then flashing other Sense-based ROMs should be fairly easy.
But after you achieve S-OFF, you need to be more cautious while flashing anything as the security would have been totally put off and whichever file you flash will be flashed without any error and may result in your device getting bricked if a wrong file is flashed.
It will be really great to backup the important partitions like recovery, boot, system etc. if you are still stock (not bootloader unlocked and not rooted)
To backup important partitions, visit this thread for instructions. (Be sure to backup your stock recovery as it will be needed to receive OTA updates) - http://forum.xda-developers.com/showthread.php?t=2701376

This is my first htc phone too, actually this is my first high end android phone. I am just as paranoid about doing anything as you, i just wanted to make sure i'm not stuck forever, because i it was impossible to change the software of this phone i would've just sold it from now, purely because imo new software adds the most value to smartphone these days. I am a bit confused, but for now i decided to not install any updates until i figure out whats possible to do without screwing up myself

I did the mistake of not backing up recovery partition after I updated and instantly unlocked and rooted my phone but luckily I got the stock recovery from another thread.

Sorry but I seriously don't know because I never took an interest in converting my device to GPE.

Help with SIM unlock & more help.

Hello this is my first HTC device and I just learnt about Hboot, Firewater, S-off, and RUU terms.
These are my AT&T HTC M8 with 4.4.2 OS on it, Just had it S-off and Unlocked bootloader.
Can I know the following things...before flashing anything onto this
1-> Can I SIM unlock it using the Config.dat method as the device was not at all updated ?
2-> Changing CID to SuperCID grants me access to all RUUs but that's not needed as I will use customROMs based on Sense and AOSP right ?
3-> In order to flash and all I must be S-off I did it So now I can use ViperROM 4.4.4 but before that the viperrom page says need for an updated firmware >3 mines on 1.5, So if I flash any will the S-off goes away ?? & found this thread here for firmware updates but it says red text, can I know whats that ??
4-> How can I convert this device to a fully unlocked device like dev edition/ international version ?
5-> Most important of all what makes this device go hardbrick and S-on again (Firmware flashing, RUU etc, Like to know what will cause this since the device is S-off can I assume this device won't brick like Nexus phones).
Sorry for this lengthy post, never used a HTC device wanted to make sure all is well.
Thanks :fingers-crossed: !!

S-OFF allows you to do all sorts
I used the Sim unlock method after i S-OFF my At&t device just because and really couldn't tell you if worked cause I actually like At&t .
Supercid does allow for flashing other gsm firmware/ruu
Yes you would want to be as close in firmware to gain the best running experience when flashing Roms above your current firmware
S-OFF only changes if you do it the way you gained it
Being S-OFF you could flash the wrong ruu and hard brick your device ( CDMA device hardware I believe could brick your device along with the wrong device kernel could also brick it )
Nexus is pretty solid but can be bricked

Thanks for the quick post :good:
So I will go ahead and update the firmware w.o redtext (just noticed it's the one that says "This build blah blah" when bootup) then I'm good to go for the flashing all stuff ??
I can also flash a non sense based rom after using sense based Viper ROM / ARHD / etc without any issues, now is my device basically a Dev Edition plus the RUU & CID editing is only needed If I ever need going back to stock (though it wont happen) or flash regional firmwares or converting to GPE, DEV, WWE editions rt ?
Lastly my device ID it says M8_UL_CA will it change after I flash a ROM or Radio or Firmware ?

Yes, you can flash any ROM. If you plan on running GPE, you will need to convert back using a WWE RUU as GPE uses different sized partitions making the system partition too small to run Sense based ROMs.
Your device ID will change to M8_UL after flashing WWE firmware, but it isn't anything to worry about.

Thanks a lot !!
While GPE is a trade off for only AOSP, with DEV/WWE I can run any ROM based on Sense/AOSP i.e GPE & including the Lollipop right ?
So before proceeding I will update the Firmware first to a 2.xx or 3.xx then run an RUU based on DEV/WWE for conversion
Sorry for so many doubts, slowly learning about HTCs devices

So before proceeding I will update the Firmware first then run an RUU based on DEV/WWE for conversion & for the last If I need to run Lollipop I should flash firmware again for v5 base or the WWE/DEV RUU (I think the Dev edition had got the lollipop Update) has the Firmware, Radio packed with it ?

The RUU contains the firmware. No need to flash it twice. You could just flash the WWE firmware if you are on Sense right now. Mostly RUUs are used to fix devices that are experiencing issues, or for converting GPE/Sense.
Running the RUU wipes EVERYTHING, so flashing the firmware is preferable. The WWE 5.0.1 firmware should be out soon, but DevEd is out now. If you wanted to convert to DevEd, there are plenty of tutorials on XDA. I'm really not up to speed on running DevEd firmware.

Found this page for all stuff & this thread for conversion.
& what's this .401 stuff in the first thread ?
I'm ok with full wipe anyways so I can use the RUU or the other recovery way for the conversion right ?

401 is International WWE firmware. For example, my firmware version is 3.28.401.9 Verizon's latest firmware is 3.28.605.4
If you are okay with the full wipe, the RUU is probably the best way to convert, but the recovery method with stock recovery and stock nandroid would work too.

Thank you verymuch for clarification !!!
Will do the work tmrw, its 2AM here

I've been fully converted GPE and back twice and after successfully converting back to Sense this last time I chose the Dev edition backup and stock recovery method followed by the proper CID&MID to take the OTA update witch is now lollipop
So basically I now have a lollipop firmware to run with the stock GPE lollipop ROM and you bet it runs great
