SIM unlock issues

So the issue I'm having is I can't SIM unlock my One... I'm running ARHD 20.2 with matching firmware. I'm on rogers and have tried two different companies (online) got the same unlock code from both and I'm unable to unlock using a telus SIM card.... any thoughts??

at least change the Cid to Rogers. if that doesn't work install venom rom, that's how I did it. if all fails, go to full stock. s-off should be fine though..

I have read many posts from owners trying to get SIM unlock. Most websites have sold SIM unlock codes that failed to unlock SIM on HTC One
I would suggest contacting the carrier the phone is locked to, Rogers in your case.
In the UK where I live, phone carrier will supply a SIM unlock code for a nominal fee approximately £15 ($24)

I ended up changing my cid back to ROGER001 and flashing a stock Rom. The code I was provided ended up being the same code rogers gave me. It worked after that. Flashed my ARHD backup now I'm good to go

New HTC One

Just picked up a new HTC one and am intending on unlocking the bootloader, installing twrp, rooting and gaining s-off. All videos I've seen and all I've read seem to be at least 6 months old, pre 4.3 update. My question is should these procedures all work on my HTC One which is already on 4.3. Just trying to avoid any issues along the way. Thanks in advance for any answers.

Yes they are still good involving the method from getting your dev code to unlock your bootloader to installing the twrp (always install the latest version) even getting your phone s-off if your on 1.55 hboot then you need to use rumrunner to get s-off after you unlock your bootloader and install trwp and get root make sure to flash a custom Rom before you run rumrunner

I just got my one as well. Do you need to flash a custom rom before using rumrunner?

I was literally just about to post a thread just like this lol. I'm not new to rooting but this phone makes it much more difficult than my prior Samsung phones. Can someone explain to me what the difference between unlocking the bootloader is and getting s-off? Also, for several hours yesterday I was attempting to unlock the bootloader but like OP I couldn't find a recent tutorial that involves getting the dev code (I actually found one but itwasn't very thorough). What exactly is rumrunner and a RUU and why do I need them, please and thank you

You changed CID and MID to Developer but you flash the Google Edition ROM. I remember the CID's are'nt the same for those two?
Allso, make sure you have stock recovery and try super CID maybe as it worked on my One.

Compatible with wind?

I have Htc One with wind. I was just wondering I just need to follow the procedures available in fourm for Htc One for installing custom roms? What about baseband, I think wind network is a little different then the rest of the networks.
