I recently unlocked my bootloader on my HTC One A9. I'd like to upgrade the software now.. Is there a stock ruu available to download for the Three carrier?

Hi Mairead, just to advise that the version number you gave me there is wrong. This is the version number for the USA unlocked version of the HTC One A9.
For Three, the most recent version is 2.16.771.4
The first digit is the major revision number. The 2nd is the firmware revision number. The third is the Carrier number.
it doesn't appear that Three or HTC have released this version of the ROM\RUU yet...
Trying to install the other version has left me with a Soft Bricked phone.. can't get past the bootloader screen
If I leave my phone into a Three shop, can they repair this?

Hi @des_irl, what guide are you using to install the stock ROM?
Unlocking the bootloader can void your warranty so if it's brought to a store for repair, it's possible that the warranty won't cover the cost. They would need to assess the phone first.
A soft bricked phone can be fixed by just getting the right ROM on there, which is why I'm asking about the guide that you're using to do this. Have you installed custom or stock ROMs before?

Hi Sheena, I'm following a couple of guides I found on the XDA Developers website, and from HTC themselves for the Ruu.
I was initially trying to install Lineage OS, but with the firmware version on my Phone (2.16.x.x), I can't (unfortunately found this out too late it appears)
I'd like to move back to stock OS, so I need the ROM.zip version to flash now. I got to the stage of actually flashing the ROM version from above, however the phone has given me an error due to a CID and MID mismatch. the CID and MID can be changed, but I've decided against going down that route, as it involves DD commands, which if done wrong can Hard Brick the phone.
I was looking for the right ROM as you can see from above, however the version number I was given was incorrect.
I have previous experience installing custom ROMs before, installing CyanogenMod on other devices and flashing Stock on devices.
Do you have an estimate cost for reloading the ROM?

Ok, I follow you now, you'll need to go back to version 1.56.401.70 for the OTA updates to work, I believe that is the European unlocked version.
It might also be a good idea to post about this on Boards in the Android section, I know that there are tons of members there that have done this before and may have hands on experience with the A9 or have a link to a ROM you can use.

Looking at the files for that version (1.56.401.70), I still don't think it covers the CID for three.. if I remember correctly the CID is coming up as H3G___003. This version covers:
You have to use a version which covers the CID, or you'll just get an error. Did Three ship the European Unlocked version? judging by the CID, I don't think they did

So, I found the firmware here: https://www.htcdev.com/devcenter/downloads. Set the region to ROI or carrier to H3G
1.56.771.70 is the version number.. (771 being the Three Ireland Carrier)
I can flash this to return the firmware to the old version, however I would still need a ROM.zip, with the same version number.. I'll try boards and see where I get..
