[Q] How to reflash stock JB rom on HTC One S (S3)?

Hello, how can I reflash the stock JB rom to my One S S3? I have flashed Superboot for Ville c2 in order to root and try changing the CID, but I couldn't change it... So I flashed back the stock boot.img in order to unroot and then relocked the bootloader. Now I'm on stock recovery and relocked bootloader. I have the OTA package: OTA_VILLEC2_U_JB_45_S_hTC_Asia_TW_3.14.709.102_16.22.20.03U_16.11.20.24_M_release_303237zzidki5gzxfkv5gs.zip.
Please help me to flash it so I can be sure that I'll get future OTA updates!
Also I don't want that SU application which appeared after flashing the Superboot for Ville c2
Thank you in advance!
Anyone...???

If you have Stock ROM with Stock recovery and you want tu update your phone, go yo About-->Software Updates section and Check Updates. This will prompt the updates you have.
if you want uninstall SuperSu, do a Factory Reset, this will erase all your phone (Make Backup Before).

I'm already on stock JB and the Check for Updates is not an option for me... I did a factory reset, but SuperSu is still there, so I want to reflash the rom... How can I do it?
guess, you have to wait when someone do a proper JB RUU. I need it, as well.

If I'm rooted with TWRP recovery, can I install an OTA?

Just curious to what I need to do to my phone in order to get an OTA installed if I'm on stock rom, but rooted and TWRP recovery?

OTA doesnt work on rooted device

Hey,
i have a rooted opo and want to update with OTA.
But it just gets me into the TWRP Recovery and doesnt proceed.
I have Version:
cynogen os
12.1..1- Y0G8DAS2K1
5.1.1
what would be the easiest version?
You can't ota with modified system and you need stock recovery, quickest way would be to backup, flash the latest cyan build, otherwise unroot, flash stock recovery and try ota again.
Where can i get the newest cyan? Searched a bit but i could only find a non flashable rom.
Full wipe is ok for me.
You can get the latest version here https://cyngn.com/support you have to flash it via fastboot then reinstall TWRP and also will have to install SuperSU for root again.

OTA Question

Unlocked U11 with unlocked bootloader, trwrp recovery and rooted stock. Have not flashed custom rom. Steps to take OTA Oreo?
Flash back to stock. Use the firmware zip it is on now to reset. You should then be able to take ota's. No need to unroot, relock etc.
Flash stock unrooted FW due twrp?
Sent from my HTC U11 using XDA Labs
Believe I have bricked my device. Flashed RUU using appropriate RUU exe from HTC. Intaller ran for @1hour with 0% process. Battery was at 93% and ran to under 30% halting process. Had to disconnect to recharge. Will call HTC to see if they can help.
Update- All cool. Battery died, charged phone boots up fine. Still on stock. Need to restore stock recovery.

If I'm not mistaken, flashing back to stock with the ruu will in affect unroot your phone. You'd still have twrp and an unlocked bootloader, but you'd have to install SuperUser or Magisk again.
Am I correct?

Flashing back to stock with the ruu will replace TWRP with stock recovery, thus making it able to take OTA.
If it's rooted or TWRP installed, it will stall at beginning of OTA process .

What if you just remove twrp and go back to the stock recovery? Would it then break root?

You could remove root of SuperSU or Magisk and then flash stock recovery over TWRP.
Haven't tried that and not sure if it would work. A rooted phone won't take OTA.
Would save restore chores if you could.

only way to take OTA is go back to stock rom by using RUU (will lost data, back to stock recovery, unroot already).
On rooted stock rom, i tried unroot and flash stock recovery by ADB but it still cant install OTA update
Flashing back to stock will unroot and flash stock recovery. If you dont do it that way you cannot update ota as the signature of the firmware is broken. You have to 're-sign' the firmware by flashing it again.
Flashing stock firmware will NOT relock or lock the bootloader. It will NOT s-on. If your bootloader is unlocked and/or s-off do not change them as there is no need.
3 essentials for the m9 are:
Stock firmware ruu.zip
S-off
Charger cable.
