[GUIDE] Sprint sim unlock & Flash

[thatotherguy..]

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://forum.xda-developers.com/member.php?u=4572661) and Rimidal (http://forum.xda-developers.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.

Set it to GSM/WCDMA perferred

 

[alberto122509]

Set it to GSM/WCDMA perferred

I don't see that as an option, but I did tried GSM only (didn't work), WCDMA only (didn't work), GSM Auto (PRL)(Didn't work), GSM/WCDMA/LTE Auto (Didn't work)

If I choose any CDMA related ones, I get sprint signal, and I can call people, even though I have the AT&T sim card in.

Looks like 100% of florida is covered, so I don't know why my phone can't pick up a signal.

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.

You tried setting the network type in *#*#4636#*#*?

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)
