markl:bradstewart:hasp: Does anyone have a backup of the stock 4.1.2 ROM for the Australian HTC One, CID Vodap021?
You will also need to a flash a stock 4.1 recovery as well if you are intending on getting an OTA or returning for warranty.
Are you saying then that if you don't have a stock recovery you *won't* get OTA updates?
Correct. CWM and TWRP recoveries can't flash the OTA's. There is some signature matching involved.
The other thing you should be aware of is if you have updated the firmware on the phone (not the software) to the 4.2 version then the touchscreen will not work with a 4.1 ROM.
If you reboot into the bootloader it will tell you the hboot and os version.
