[GUIDE] Sprint sim unlock & Flash

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
here's a video also if you get stuck

ok so Recognized Developer -viperboy-(http://forum.xda-developers.com/member.php?u=518868) made a app to help make it easier if some people
like before all credit goes to him, he just asked me to post in op
here's is the google play link https://play.google.com/store/apps/details?id=com.viper.simunlockhelperfree
here's a link to his thread, if you have any questions it's best to post there about the app
here's a link for ppl that want to flash there phone,here's a guide on how to flash sprint htc one http://www.cricketusers.com/cdma-htc-one/85426-how-flash-sprint-htc-one.html how to get spc code and how to connect to qpst

First and thanks for sharing
Added to my FAQ Guide Q24

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:

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

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.

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.

[Q] Has anyone manage to connect to metro pcs gsm?

I figured I would try asking. I get edge data and calls are working. No 4G though and I havent tried MMS yet. I called metro's tech support for their apn settings and they don't seem to work.
If you have your ATT Note 3 working on Metro's gsm service, please share your settings/experience here. Any ideas on how to get this working would also be great. Thanks in advance! :good:

I bought two Note 3s and gave one to my friend who's on metro. Everything works perfect for him, 4g, MMS and everything else.
He Input his APN settings so I'm not sure if he did anything else. When I get off work in the morning I'll ask him if he did anything specific besides the APN settings and let you know.

Yeah, I have tried LTE/GSM auto; LTE/GSM/CDMA auto; and a few different other ones. I always only end up with edge.

I have a question for you, did you buy the phone and stick your sim card in, or did you actually go to the Metro store and have them program the sim for the phone? Metro's sim cards work different than most gsm carrier sim cards =/

I went to an actual metro pcs store and bought the sim. The employee scanned the bar code on the back of my phone, so I'm guessing they programmed it specifically for my phone.

Ok so called my friend today. He told me that he didn't input the APN settings, they loaded automatically. It did make an APN profile for him. He sent me the following screenshots.

I also noticed that too! Yes he does normally have 4g/lte. His home is one of the ones where you take one step to the left and you have edge. Happens to me too and I'm on At&t lol. Let me know if you have any luck with it.

How are you suppose to know what the password is and the server as they are just **** in the screen shot?
Sent from my SM-N900T using xda app-developers app

No go on the apn settings. I am planning on driving out to LA sometime later this week and will check out whether this lack of LTE is only in my area. Sucks coming from metro's great cdma service.
Also quickvic has a good point about the password, although I'm thinking tyiphius friend's apn settings were installed automatically

Anyone know where I can buy a N900A note 3 that will work on Metro LTE?

Working AT&T LTE for Verizon G2

I just updated my G2 to 4.4.2 and noticed that I am getting LTE for AT&T. I was wondering if anyone else was getting this?

That is very weird... Mine clearly shows Verizon Wireless
Have you ever used a AT&T SIM (AT&T, Go Phone, Straight Talk, Aio Wireless, etc) in your phone?
Is there Verizon 4G/LTE in your area? If you install and try Network Signal Info does it show Verizon or AT&T and what type of signal?
Completely stock?

Weird... Try going to Settings->Tethering & Networks->Mobile Networks and make sure Global data roaming is off, System Select is LTE/CDMA, and Access Point Names is set to VZWINTERNET... If that doesn't work, I would take it in to the local Verizon store, this is not normal and could be an indication that your EFS partition is corrupted.

AT&T in your area must have band 4 AWS lte just like Verizon has thus it works. I would try this if AT&T actually had lte in my area, but they do not yet, strictly a pcs carrier here, besides lte.

Yea I was a little weird looking at my phone and seeing the LTE and checking the speeds and getting about 3x faster then HSPA+.

How is yours even like that?
How did you get it to look like that? My Verizon g2 won't even show 3g or 4g. It only shows H. Did you flash your phone? If you didn't have 4g LTE, would it show an H?

Yes... H means HSPA(+) that's what you get when your on high speed (non-LTE) data on GSM. A VZW G2 will only get LTE on AT&T in about 13 markets in the US as that is the only places they have Band 4 LTE, I don't remember them all but Google can fetch a list of them pretty quick I'm sure.

[Video] Verizon On my nexus 5

Took the sim out of my Verizon s4 and was determined to get this N5 up and running on big red.
I have full lte after a lot of tweaks that I probably shouldn't post right now do to what it could possibly do to a phone.
If you are a Dev and think you can do more with this let me know and I'll get you to where I'm at. I'm just a themer with basic dev knowledge. As you can see there is no signal to text or call. I've had bars a few times but that's it. As you see I'm on L. I had to crop one screen on phone because of upload size restrictions.

Looks interesting so far. I can't recall whether this device supports VZW's frequencies. If not, calls may never work.
I'll assume you modified the APN for VZW. Did you try modifying the radio?
If you post what you did to get data working, other members may have some additional suggestions to get you moving again.

its been gotten to, the lte connecting. but it's the calling ability that cant be done. i dont remember what all really came about, but i do remember thst the calling ability is the real issue. the nexus 5 doesnt have the ability to make phonecalls via lte. if you search the forums here, maybe you can find the thread.

Calls won't work for two reasons 1) I don't think Verizon uses VoLTE yet, and 2) calls still use 1x, just like Sprint, and you have to have the MEID (IMEI minus last digit I believe) in Verizon's database. Technically it should work on Page Plus and I think I saw a thread here on how to flash it for PP. I'm kind of surprised Verizon LTE works as most of the bands for Verizon's LTE don't coincide with the N5 IIRC. I could be wrong about that though. Also it's probably like any other GSM carrier, once you activate the SIM card in a carrier based phone, you can stick it in another phone and it should just activate. The only reason you have to change IMEIs is for the EVDO/1x backwards compatibility.

i may return to big red, im currently testing out net 10

Posted a video of me getting data after a fresh wipe and install of L.

http://www.droid-life.com/2014/08/26/verizon-volte-hd-voice-launch/

I really need to remember to watch OP's video when I get home. This is very exciting. So to get data, you had to activate a Verizon device and swap SIMs, right? After that, the only thing not working is the CDMA voice? So in theory, if the above poser's link is correct (Verizon rolling out VoLTE soon) I could actually switch to them?
It's Verizon so I probably wouldn't do it permanently, but it would be cool to try for a month, if for nothing more than a proof of concept or neat trick. Hope Verizon does that soon.

This just won't work bro, not on CDMA.
I worked for Sprint and their system is the same.
The SIM card is strictly for LTE, everything else goes over the CDMA network, which requires server authentication.
Even when VoLTE will roll out, that authentication will remain in place.

People have got data in the past. Its voice that's the issue.

he can get voice & sms on it, though not via the sim card number;
I replied to the video with -
"..though it won't be your Verizon mobile number;
you could try using ring.to / grooveIP for voice / sms via the lte connection..
I use that as a back up number on sprint, mostly for lte , wifi , evdo routed calls,
even gsm / hspa+ & wifi when sim swapped out of the country on my nexus 5.
after editing the echo settings, it should work wonders thru that Verizon lte connection.."

just thought of something, real simple..
the cdma radio authentication is what's stopping the nexus 5 from being on Verizon,
but... **does the lte band need the same authentication**?
let's just say, on my nexus 5, with the new google voice hangouts / sprint number integration,
i go through the dialer into settings to toggle **lte only** which disables the cdma radio,
pop in a Verizon unlimited data sim, in an area with verizon's band 4..
over the top, voip service on lte..?

also, HSPA, LTE, GSM, etc is not the band type, its a network type.. by Band type I mean LTE: Bands: 1/3/4/7/17/38/40, which is also another way to describe radio frequency

That's all fine and dandy, but it's not like your carrier is operating multiple frequencies that you're likely to see ever. Maybe if you live in an incredibly dense population center, but even then... Perhaps I'm missing something.

Fair enough, if you have LTE already, and they are simply deploying a new frequency, you likely won't notice any change, to any of the service. Speeds don't increase between bands, the only reason a carrier deploys a new band, is to fight radio interference from other carriers. Given the cost of a single radio, carriers generally only deploy these new radios in VERY congested areas. Meaning, that in a city that has, say 15 towers, 2-3 of them would actually get the upgrade, in the area that suffers from the most interference. (You have to bear in mind, that a full tower build, requires 6 radios, each radio costing about $18,000 for the radio, another $1000 for the antenna, another $500-1500 for the power supply and cabling. They don't just "upgrade" an entire area, it takes too long to recoup costs)

Ah my mistake, i had in my head he meant to check for bands in the area which he can use with the 'unlocked' frequency mod..for some reason. My total mistake!
However what i meant with what i said when i get my 4g is that i can confirm that the unlock mod will enable band 20 since our OPO is restricted/doesnt support it by default. The band app would be good though!
