[Q] Unlocking bootloader ( htc cha cha ) HELP Plz

downloaded the RUU for my country but it gave me :
ERROR [191]: ROM IS NOT SUPPORTED
My current software version is : 1.20.720.1 ... android 2.3.3
It says it needs version 1.57.720.1 for HBOOT update.
I haven't got any OTA update ( I also checked manually) to update to 1.57 version.
I couldn't unlock bootloader because of this and I still don't have root. and custom roms ..
Any help will be appreciated.

I tried by running ruu_chacha_htc_asia_wwe_1.57.707.2........ google it and you will find the RUU. run the RUU in administrator mode and you might have to try 2-3 times. Not remembering exactly how many times have to run it, but finally could upgrade and could generate "Unlock_code.bin"
I used customs ROMS and the best I found was SuperOSR chacha 2.5
Today only I have managed to downgrade to 1.20.720.1 and successfully restore the indian RUU. So now my Chacha is back to factory. Locked again.

You are writing weird specs from your phone:

But above you mention, that device is S-Off with Supercid. To get this, you must be that! What's the fact now?
Above you write, you have Android 4.1.2, but this would be Software 2.14.xxx.x and you are writing 1.17.401.5, what does not fit together. Also hboot seems to be the first one.
So i think, you don't have stock recovery or other things not stock, that is why OTA fails!
Have you tried to flash the k2ul RUU to restore everything stock?
More information, please!

i just update my device from its original ICS stock ROM to its latest update 4.1.2. Not yet been rooted. and recenty bootloader is unlocked. and i haven't tried to flash r2UL RUU..
Do i need to downgrade or reflash it back from its original stock ICS 4.x.x so that i can update it to the latest update 4.2.2 and skip 4.1.2 software update?..
Is the right RUU for my phone..

for my device.

But if you have 4.1.2, why are you talking about Software 1.17.xxx and hboot 1.01?
That does not fit together. And until this is not finally solved, i won't give any solutions (which could be wrong, based on wrong information).

and upgrade it to the latest Android version 4.2.2 directly.

I understand, what you want to get, but in short words:
Software 1.17.401.5 IS NOT Android 4.1.2!
So your info is misleading.

Please help me.. What should i do?.. I want to upgrade my device to android 4.2.2.. :crying:

You can try to flash the RUU (you've already found), but on your own risk.
If that is successful, run all the updates.

So it means i should give it a try.. to do flash RUU downgrade.. and do software upgrade (not andriod version upgrade).. please confirm so that i can start now. and give you a feedback if it really works..
Sorry for my terms.. What i mean is "Software Version Upgrade" and not "Android Version Upgrade".. Maybe i'm confused between Software and Android Version update.. Thats all.

If your hboot is 1.xx, your device is S-off and you have Supercid (like written in your info), it can work.
And then it would be more a software downgrade, than an upgrade.

that's OK.. i better downgrade my original software version, android version (ICS) using this tutorial. and maybe also includes HBoot downgrade [ Click Here ]
After i downgrade. and upgrade.. It will skip the software version 1.17.401.5 and proceed to the latest one?..
Sorry i keep on repeating what you are saying. i just wanna really clear all things?..

Off topic question : What's the problem while installing an update if there is phone with a question mark icon?..

You don't need to downgrade hboot, because related to your information you already have the one you need.
The OTA fails because your device is not stock and/or files are missing.

OK. Good to know that i don't need to downgrade my HBoot. Thanks.
I'll read first the tutorial about downgrading my device using RUU and then i'll proceed.

Good to know that i don't need to downgrade my HBoot.
So it means that i can skip the process of downgrading CID because my device is already SuperCID?. And i can start directly RUU Downgrade?.

I'm here, let me read through this then I'll post my thoughts

Converting AT&T carrier unlocked HTC One A9 from stock 1.27.502.5 to Nougat

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!
Best,

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.
Best,

You would simply have to revert your CID back to CWS__001 and flash the at&t ruu. Changing the cid is easily done.

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.

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.

Eu to Us Unlocked ?

Hello,
I have batter issues really bad and I wanna try us unlocked. I have one a9 eu and my cid Htc__m27. My version 2.17.401.2 and I want to use 2.18.617.30 it's us unlocked. I think I should open my bootloader and root my phone then I should s-off locked method with sunshine and load 2.18.617.30 ruu that's right. Can I take update from ota after this ? And which twrp and supersu version should I use ?
