I have an HTC One Developer Edition in Canada.
Still no update for me. Any other owners out there of the DE who didn't get the update yet, or am I the only one (starting to feel like that)?
No developer edition has recieved the update yet. Basically they are releasing updates based on CID (which is the ID of the device per territory).
My CID was VODAP001 which means Vodafone, European unlocked. This would mean I would have to wait for Vodafone UK to rollout the update.
In order to get the 4.2.2 update straight away I unlocked my bootloader via HTCDEV.com
I then used the REVONE hack to enable my phone to have S-OFF. With S-OFF you can modify the model ID of your device. Thereby making it any other territory version or even a developer version.
I gave myself SUPERCID which is an almighty CID that allows any 'OFFICIAL' stock recovery rom to be loaded regardless of territory.
I then flashed the stock RUU recovery rom from a territory where the rollout has officially happened.
Once this was flashed onto my device, I changed the CID to that country HTC_Y13 and then checked Software Update, which in turn downloaded the updates including the very latest 4.2.2 update.
Afterwards I changed my CID back to SuperCID in case I ever want to go back to a different RUU.
It sounds complicated and I was nervous but it all worked.
So now I have the latest software, and the ability to flash a stock HTC recovery image (RUU) from any territory or device.
