so the on in Q&A is getting full of nothing so time to start one with the guide

I don't take any credit just posting,,,All credit goes to hotaru2k3 (http://xdaforums.com/member.php?u=4572661) and Rimidal (http://xdaforums.com/member.php?u=1468774) for writing step by step and video

first off you need to be on stock sprint rom or base for this to work. also it will work on bad esn phones

1. You should be rooted
2. Download https://play.google.com/store/apps/details?id=jackpal.androidterm
3. Run Terminal Emulator
4. Type "su" (excluding quotation marks) and grant it superuser permission
5. Type "am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity" (excluding quotation marks)
6. You will get menu on your HTC
7. In that menu, select "API", then scroll down 'till almost end and select "simlock"
8. Reboot the phone and hopefully it would accept GSM SIM
9. Enter *#*#4636#*#* in your dialer
10.In the phone information section(the first one) set preferred network type to something that is GSM specific: "WCDMA Preferred", for example. The phone will switch to GSM mode

I will have a sprint htc one in a day or two to try this, but I haven't seen much mention of data. Is anyone picking up HSPA+ with the sprint htc one on gsm?

It really depends on area. Read below:

HTC One supports: GSM: 850/900/1800/1900 MHz and WCDMA: 1900/2100 MHz (with HSDPA up to 14.4 Mbps)

which means that in areas where ATT uses 850mhz for HSPA(3g/4g) you will not get anything but edge/2g at best. And in areas where TMO uses AWS for 3g/4g... you will not get anything but edge/2g.

In areas where ATT has 3g/4g on 1900mhz you will be able to use it. And if TMO has 3g/4g on 1900mhz you will be able to use it.

ATT/TMO LTE will NOT work.

So I went to an ATT Store and picked up a free gophone sim card, I activated it successfully online, I have a phone number and added $10 to the account.

I followed all the steps to unlock, I also set it to WCDMA Prefered.

But I'm not picking up any bars.

TMobile sims seem to work better for some reason.

Make sure you have GSM Data checked in the network settings. Then you should be able to scan for networks.. see ATT listed.. click on ATT and it will try to register.

Yea, I tried all of the GSM and WCDMA ones, I tried changing the APNs, tried flashing a bunch of different roms, I actually ended up screwing my phone up (I couldnt get any bars with sprint, 4g worked, not even an RUU fixed it, but I found a way to fix it)

    Hey guys, I wrote an app that will help you guys with this process. It's very simple, it has the instructions in the app and keeps you from having to use terminal emulator. It will check for root access and make sure you have the right device as well :) let me know how it works for you! OP, feel free to add this to the first post.

    The link above is where you should post for issues/suggestions for the app ONLY, not to talk about SIM unlocking in general, as there are already two threads for that.

    What i did to get the at&t sim to work on my HTC is go to settings take out your sim, turn off mobile data, then put your sim in. After that quickly open up The mobile network settings go down to available gsm networks and do that search networks option and choose at&t. you have to do it before your phone can fully read the at&t sim card because once it reads it, it wont let you select, search networks. I had that same problem where T-mobile would work but at&t wouldn't so i got desperate and tried that and it works fine. I get 4g lte speeds and all of that. Though whenever I am in a building and lose my service I usually have to do that process all over again.
