I was wondering if it is possible to use the patched RUU instead of shell tool to flash roms on a CID Locked G4 Wizard. I have the RUU that comes with wizard love, its a foreign language. With that RUU I can flash Wizard Love just by running it. I tried mfrazz's logo update patch which comes with the english RUU but that gave me an error, the with english RUU that came with the Cingular Radio rom. However, when I copied to nk.nbf files and used the Wizard Love RUU installed I was able to install it. I'm wondering now, if I can just use the the wizard love RUU installer to install an OS rom, instead of using ShellTool. Does anyone know if this is possible?
Thanks.
It should be NO. It is confirmed that the only advantage of a unlocked G4 is the ability to use RUU to flash ROMs without G3 IPL/SPL.
And the RUU used must still be NoID version.
Just to add to the post above - if you do fully CID unlock your G4 you have the ability to flash bootloaders made for G4. Certain ROMs contain the new G4 version of IPL/SPL3.08 BUT make sure you read about the ROM first before attempting any bootloader flash. I think the AKU3 ROM from German T-mobile contains it.
I'm a little confused with the bootloader stuff. I just wanted to know if it would be possible to use the RUU tool to flash and OS on the my wizard instead of shelltool.
Also is there a sure way to check if you are CID locked on a G4 wizard?
Thanks

I see where you're coming from, but it's not possible to flash a WM6 rom with the RUU. Let's try to explain:
The RUU works for certain 2.26 roms (like wizard_love) and things other than OS like splash screen and radio only roms. When you use the RUU with WM6 it will go to 100%, but the OS that will be loaded afterwards is your old OS because of the CID-lock.
If you pay to unlock your CID, then you can use OS-only RUU to flash.
Dear All,
I just S-off and rooted a HTC Sensation 4G the cid when it was S-offed and rooted was cidnum: T-MOB010. I have as a newbie had wiped my original stock ROM but I do have a backup. From what i read from the forum adb tools require you to setup the phone in USB debugging and change to charging mode. Right now I do not have a ROM installed. My question is , is there anyway I can change the CID to superCID so i can install any ROM. I'm trying to find ROMs to work on my htc but still no luck. I was wondering whether if I superCID'd it then i would have a better chance. THanks!
Don't think you can. You must use ADB. Sorry
Can you suggest a ROM for me if possible so at least I can install it and then change the CID. I was looking over virtuousrom where there is support for t-mob010
Thanks in advance for the help!

I'm not sure what that is, I don't live in US but if you need a great rom, I can suggest a few.

Virtuous Inquisition is a great senseless rom, i've been using it for a few months. Smooth and all.
But if you are a sense lover, you can go for InsertCoin

You need to SuperCID via ADB tools.
You can run the ADB commends required even if you do not have a ROM installed as it uses fastboot.
You do NOT need to have SuperCID in order to install and use a Custom ROM.
What does your Bootloader screen say at the moment ? As in have you still got GB compatible Firmware or ICS compatible Firmware ?
As the person above me said, you don't need to boot your phone in order to supercid it. Do what is said here http://forum.xda-developers.com/showthread.php?t=1192300 and skip steps 5,6,7.
And to install a rom, you don't need to supercid... just install the firmware it asks you to install and then, install the rom. I'd recommend ARHD 6.3.0, get the firmware package for your cid from here: http://forum.xda-developers.com/showthread.php?t=1459767 (just be sure to take the 3.30 one) and follow this guide: http://forum.xda-developers.com/showthread.php?t=1471941
P.S. Any rom is compatible with your CID as long as you have the right firmware package I think. (Just wait for someone to confirm what I'm saying, because I'm not sure)

Any custom ROM will work with any CID, assuming compatible firmware and radio. You need the "appropriate" CID to install RUUs. For example when I first got the phone the first thing I did was to change the CID and install a generic European RUU to debrand it.
EDIT: compatible firmware relates to the HBOOT version and has no relevance to the CID itself. There are compatible firmware/radio combinations. The appropriate Radio is included with the ICS firmware packs.
Note: If you revert back to 1.17 HBOOT for GB ROMs you'll need to flash an appropriate Radio. There is a thread in the dev section: http://forum.xda-developers.com/showthread.php?t=1178143
The reason there are so many CIDs mentioned in the firmware thread, is that many CIDs seem to have popped up for the Sensation and many folks didn't SuperCID. The reason in that thread for so many installs for groups of CID versions of the firmware, is that there appears to be a limit on the number of characters in the section that checks the CID. ALL the firmware downloads are the same (for the same HBOOT version), they just do different CID checks. If you're SuperCID and of them will work. I hope the explanation isn't too convoluted.
Does anyone know that if I can change the CID of my sensation z710a with ADB WIFI as the usb port is not working?Thanks.

Hi
I've just change my phone from HTC HD2 to HTC One S(S3). Unfortunately device which i bought is branded in orange. My question is how to change Orange CID to HTC__B25 ? I supose that procedure is thesame as a change CID to 11111111; i'm right ? Finaly i want to have a stock rom, stock recovery and OTA updates (without fear to make a brick after update to JB). Please help
P.S I would be grateful if someone write procedure step by step

With CID 11111111 you can install any rom.
In my case to update radio to the latest one, I flashed phone with RUU (having CID 1111111111), I got all OTA updates.
My radio now is up to date.
Now I'm on Pac Man 23.0.0 rom with latest radio, latest kernel, hboot 2.15, S-OFF, "Super"CID (1111111111).
Anyway you can update CID to any other, it's exactly the same as a change CID to SuperCID(1111111111).
Yep, Just in case.. I'm S4 user.

To change the CID on your phone you would have to be S-OFF, which is not currently possible on S3 devices. Sorry friend.
If your soff you can do it via a simple fastboot command.
First check existing:
Fastboot getvar all (or use cid instead of all)
Then change it:
Fastboot OEM writecid ........
Always 8 digits. Like HTC__001
Then reboot bootloader, get in fastboot again. Check it with the getvar command.
Know what you are changing to, and why.
Use at own risk!!!

Actually there is only a ruu.exe for the US unlocked version af the a9 so that fits not wth your device.
But you need to get S-OFF first, then change cid and mid and convert to US unlocked and than your good to go.
Link to the thread for converting is here. https://forum.xda-developers.com/one-a9/development/s-off-convert-to-htc-usa-unlocked-1-12-t3271861
Take the latest mm 6.01 rom-zip to convert and then take the ota or use the ruu.exe

Technically yes, you could flash the system.img, but you would also need Nougat's boot.img. Nougat's boot image will not boot on any older firmware.
To upgrade to the firmware from a different MID/CID, you NEED s-off.
Bottom line...you need s-off to upgrade to the Nougat release from the US Unlocked variant. There is no other method.

Sure...the RUU is here. It will cost you $30 to get access to it.
If you want a system image, you can extract it from any RUU you wish. You'll need the RUU Extraction Tool, which is available in another thread here on XDA. The OTA is designed to only patch certain portions of an existing system partition. OTA zips do not contain a system image.
You can flash the Nougat images through recovery if you want, but THEY WILL NOT WORK. You will soft brick your phone! It will not work! The firmware (radio, bootloaders, etc.) are different! 1.xx firmware is not compatible with 2.xx boot images!
If you want HTC's Nougat on your phone, you have three options:
1. S-off your phone and follow the convert to US unlocked guide.
2. Wait until if/when Nougat OTA is available for your A9 variant.
3. Buy a phone that is already officially supported.
Please take the advice provided to you by @MGfusion, @alray, @scotty2000, me, and possibly others in multiple threads on this forum.
If you are unable to s-off, you will not be able to use the software contained in the Nougat RUU for US unlocked at this time. THERE IS NO OTHER WAY.
If you are unable to follow instructions, nobody on this site will be able to help you.
I would advise you to stop modifying your phone until you've done more READING on this forum. Without the proper RUU, s-off, or unmodified image files, you will not be able to return to stock.

Hey All,
Apologies if this is obvious but I couldn't figure it out myself looking at the FAQ's etc.
I just purchased a new HTC One A9 which was carrier unlocked by AT&T, and I want to convert from the RUU version they use (1.27.502.5) to the latest version that HTC has released on their website - 2.18.617.10 .
However, when I go to do this using that RUU, I get signature error 132. My phone is bootloader locked and S-ON, but from reading a little, I thought that shouldn't matter because I have a US phone, and you only need to change the CID/MID stuff (whatever those are) if you're in a different region?
How would I go about doing this? From reading through a bunch of posts, do I first need to switch to an unlocked version of Marshmallow, before then upgrading to Nougat?
Edit: Upon further reading, does the fact that the 502 in my current version does not match 617 in the one I wish to upgrade to mean that I can't do this with S-on? Do I need S-off? If so, how do I do that? Is it only by purchasing sunshine?
Thank you for your time!

In order to convert to another carrier version, you must change your CID and MID to match the RUU version you want to flash. .617 uses the same MID as .502 so you'll need to change your CID only from CWS__001 to BS_US001. Changing CID does requires S-OFF (Sunshine is the best way unless you know someone with a XTC2Clip box).
You'll also need to update your firmware to Nougat before flashing the Nougat RUU because of the signature change implemented in Nougat.

Okay thanks so much Two more quick questions.
1) Does changing to S-off have any consequences in terms of a future update? I'm guessing it will void my warranty, but say I wanted to go back to using AT&T's version of android. Would the fact that my phone is now S-off prevent me from using their RUU (assuming I change the CID back.) I guess my question is, warranty aside, is there really any negative to turning S-off?
2) This is more out of curiosity. HTC One Phones that were sold unlocked/developer that are currently running Marshmallow can be upgraded to Nougat without flashing the firmware to 2.xx.xxx.x right? So if I was to change my current CID to that of a developer One A9, and install that Marshamallow RUU say (1.57.617.60), why wouldn't I be able to simply update from within the OS as they do?
Thanks again for your time.

S-off gives you full control and access to all partitions which mean there is no more mechanism preventing you to flash incompatible software/firmware on your phone. Once s-off, be sure to understand what you're doing before flashing files. The risk is limited if you'll only be converting to another version or flashing custom roms but if you're going to explore a little deeper yeah it can be dangerous.

All A9 can simply be updated from the OS, not only the unlocked/dev version. The reason why you need to flash the firmware first before flashing a RUU is that HTC changed their encryption signature in Nougat. That mean your phone need the new decryption key to be able to flash Nougat RUU. Flashing the firmware first will update your phone with the new key, making it able to flash Nougat RUU.
There is a firmware.zip file inside ota updates. When you install an ota update from the OS, the first thing that is flashed on your phone is that firmware.zip. So no you don't need to manually flash the firmware because it's done automatically in the ota process.
Yes you could flash the 1.57.617.30 ruu and do the ota update after. It's just faster to flash the Nougat firmware first and the Nougat RUU instead of flashing the Marshmallow RUU and downloading + installing 2 ota udpates, well that's my opinion. Both methods will give the same result.

Edit2: I figured out the problem. I had to boot into the bootloader and then run
Code:
htc_fastboot oem rebootRUU
before I could run the RUU sucessfully. Am leaving the rest of this post up just so that other people googling this have a touch point.
Okay so I've used Sunshine to turn s-off and unlock my bootloader. I then changed my CID to BS_US001.
I then tried to install the HTC version of Marshmallow (maybe silly, but heard people having issues with Nougat and the battery) using the RUU.exe file. It started successfully, but then halfway though, after it had transferred the ROM over, it threw an ERROR155 and aborted, leaving my phone with an empty progress bar, and that circular green arrow icon in the middle. I used the command line to restart my device and had to factory wipe it, but otherwise not the worse for wear.
I tried googling it; do I need to relock my bootloader for the RUU.exe files to work? I think the Sunshine FAQ recommended against doing that. Is this a risky step?
Edit: Here are some instructions I found from the HTC One M8 firmware flashing thread. My error says "unknown" but I imagine its similar.
For “Error 155 relock bootloader" do:
- Since my thread works only with S-OFF phones anyway, this error can be read as: you need to S-OFF first!
- Error 155 can mean that you need SuperCID. On a few occasions this was shown when the RUU/FUU refused to run because of a wrong region lock.
- Lately, Error 155 has occurred when a FUU was launched from within android. When encountering a FUU error 155 with the process stalling after the rebootRUU (stuck at black screen with silver HTC logo), please just restart the FUU and leave the phone in that mode, or reboot the phone, then reboot to bootloader, then do “htc_fastboot oem rebootRUU” and then launch the FUU again (thanks @anarchychris for pointing it out).
- run the fastboot command “htc_fastboot oem lock" - only applies to S-ON phones that want to update the firmware with a stock OTA package (not offered on this thread!!). Stock OTA files sometimes need a locked bootloader.

In order to convert to another carrier version, you must change your CID and MID to match the RUU version you want to flash. .617 uses the same MID as .502 so you'll need to change your CID only from CWS__001 to BS_US001. Changing CID does requires S-OFF (Sunshine is the best way unless you know someone with a XTC2Clip box).
You'll also need to update your firmware to Nougat before flashing the Nougat RUU because of the signature change implemented in Nougat.

How do I get started to do this. How do I find out my mid Cid and if I need to change? How do I flash firmware first? I have android 6.0 software 1.27.502.5. I have done a run before but never changed from a carrier. I went to the link above but I don't know what some if this means and where to start and what steps to take in order.
