[Q] Evo to Metro PCS

I got an Evo for the intention of flashing it to boost mobile. Then I saw virgin mobile and decided i wanted to flash to them instead (same service half the price). I ended up going with metro pcs and I spent maybe 12 hours today working on this thing. I CANT FIND ONE TUTORIAL THAT WORKS! Also I'm now finding out that you cant use the evo with 3g in New York, apparently that's where I live hence a problem. Can someone point me to a good PRL, Tutorial on how to flash to metro, and a funny picture that can make me happy because I'm very angry.

can someone respond? i have a $500 touch screen desk ornament just hanging out...staring me down, mocking me

Dang 1:49 minutes, relax...
First off, you can't just flash your EVO to metro yourself. You need to go to a metro store and have them add the ESN to their database. This will active the phone and get it working for talk and text, just get the $40 plan!
To get MMS and web working follow bloody's info and flash his ROM to make life easy.

Now to make you mad, Metro does not have 3g, you will only get 2G. The good news is there are ways to potentially get Clearwire 4G working for either free or cheap.
Virgin Mobile won't active the EVO since Sprint owns them and they don't want people flocking to the cheap plans. If you find someone that will actually do this let me know I would be very interested!

My esn is already in their database and I had service until I flashed my prl and now I have no bars can someone post the sprint prl for new york and had was it clear wire for free

If you want Metro to work you need a metro PRL, search around it is easy to find, howard forums has a sticky, the PRL you need 02004
As for clear do read bloodykiller86 metrodroid ROM thread I posted info there on how to get clearwire to work.

[Q] A couple of questions from a somewhat of noob.(wimax,metropcs,full guides)

First of all, I would like to thank all the members on xda who have worked on the evo for metropcs! So, after countless hours of research and trial and error I was able to get my evo flashed to metropcs. As was doing this, I ran into a couple of problems/questions that I would like someone to address(or can redirect me where I can find that information):
A. It seems to me that most solution to "flash" a phone to metropcs assume that you already have tallk and text on your phone. Why?
B. To get talk and text I had to modify the nam settings and write a metro prl using cdma. I then had to pay someone on ebay to put the esn into metros database. Would the same settings apply to most phones(evo 3d, nexus, iphone etc) ?
C. Besides ebay, does anyone know where I can add ESN's into metro's database (I tried my local stores but they didn't want to).
D. This last question is just out of curiosity: I know metro has lte and sprint wimax and that's why the evo can't get 4g. But, what if we change the WiMax settings(in particular the NAI) on a flashed phone to that of a evo that is on sprint(of course with the person's permission). Would the phone get 4g from that person account?

[Q] Note 2 from Sprint to Verizon, basic questions

I got a galaxy note 2 with Sprint on it, and plan to switch over to Verizon wireless (I use one of those 3rd party companies that use Verizon lines) and I heard they don't like unlocked phones. I have a few basic questions, please note my phone doesn't have a SIM card. I like Sprint, but their coverage is more city based, and the problem there is I don't live in a city, and big red has got us covered under 4G LTE.
Will I be able to pick up a Verizon LTE service, I remember there was some sort of error with my older S3 and it roamed on a Verizon 4G network, i'd assume my Sprint note 2 can do the same, and is capable of picking up that signal.
Also, will the company be able to know I have an unlocked phone? Or will it assign me a new MEID with Verizon when I select that option, (Yes I know how to unlock, real simple process) And when I go to type in the MEID/ESN for activation, will it recognize it is on an unlocked phone, if so how do I fix that without doing anything illegal (Like changing the MEID, which is very complex, and illegal)
And will I be able to keep my current MEID I have on Sprint, if I select Sprint under the network options.
If you are confused on my wording, i'll be glad to help you out. Also if you know anything about the HTC One M7, will I be able to switch that over too, and would I also need a Verizon SIM.
Thanks for the help, I am not an expert so try not to be too complex, I also perfer to avoid CDMA tool if possible, I dread that software at times.
If there's also a way if 4G won't work to trick it into thinking I have a 3G only devise under Verizon that would be cool too. I don't expect this to even be possible without a dreadful process.

Bump, not sure if you are supposed to do this.

Unlocked Sprint S6 on Verizon?

I have an unlocked Sprint Samsung S6 and I'm trying to get it to work on Verizon but it doesn't want to work. It shows an exclamation and R where the signal bars are. I have tried setting up the APN and a Verizon rep put the sprint phone in their system, but that didn't work either. Is there any way to get this to work? Do u have to flash Verizon's Rom to it? I noticed that even unlocked it still seems to have the sprint activation stuff..... Please help, scoured the Internet and forums to no avail :/

If you actually got the phone activated onto your line on Verizon, you will need the Verizon PRL on the device for it to show it connected natively to its towers (the 'R' is a roaming indicator...your device is seeing the Verizon towers as roaming since it loaded with a tower list with Sprint towers prioritized). Verizon is still CDMA, so you will need the proper PRL flashed to the phone for it to work, first & foremost, along with your NAM information and all of the Verizon data settings flashed in place of the Sprint data settings. With regard to CDMA switching from Sprint/Sprint-based to Verizon/Verizon-based, there is more to it than merely an ESN swap (activation by an agent) & inserting a SIM.
I am not here to hold your hand through the flashing of anything, but I'm letting you know what will need to be done. These phones have different model numbers for a reason (unlike "hybrids" like newer Nexus devices, newer iPhones & the recently released Moto X Pure). These different models are designated per carrier and the bundled carrier software for many CDMA devices is used in its OTA programming. Sprint devices typically are packed with MSL/SPCs unique to the device and needed to edit the internal NAM & data settings while Verizon branded counterparts have 0s instead of uniques codes. If this is all over your head, you may need to seek the assistance of someone or a company familiar with flashing to get you going if you are hellbent on using THAT device. Good luck.

worked for me but not stable
I also have the s note 5 from sprint and been trying to make it work on verizon. After so many tries in the mobile network setting i got it to partially work. it still have the R symbols on top, which shows your roaming but you will get a 3g speed. My current setting is
Settings>Mobile Networks>Network mode >automatic
Settings>Mobile Networks>data roaming>Roaming network>automatic
Settings>Mobile Networks>data roaming>Roaming guard> all off
Settings>Mobile Networks>data roaming>everything else on
you also have to use the verizon app settings.
i've also tried flashing the prl but had no luck. Any suggestion on how will be appreciated.

So, how about an idiot's guide for making this happen?
If I need help from a vendor, how about posting some referrals, what needs to be done, and how much is fair to pay?
I am a self-professed newb and I just want to take the Sprint S6 that I own outright to Verizon.
Especially because I paid full price for the S6, and Sprint's service sucks inside my building.
Thanks .

What VicFreeze said above is 100% correct, you would have to reprogram/flash the phones CDMA chip/radio and even Verizon will not be able to do so (legally or maybe not smart enough to know how), you want to be on Verizon you need to get one of their phones. Your phone is a G920P, the P is specific to Sprint and the phone has been flashed internally to know the MIED, MDM/MIN, PRL and login passwords for their networks along with the MSL Code direct from the Samsung factory just for Sprint.
So Yeah you can change all this by reprogramming the CDMA chip inside the phone, first you need professional software that will cost $$$ hundreds of dollars, software like CDMA workshop, QPST or DFS will work, learning to use this software is not for newbies, you will also need to get the information from Verizon to flash their carrier specific codes and numbers into the phone, it's not like swapping out your SIM Card like a GSM Phone and your on a different network, this is CDMA and its why Sprint/Verizon use this, its to lock you down. (no, that's not why)(LOL)
Just Google "Carrier programming on CDMA phones"..
I think it would be cheaper to sell your Sprint phone and just get a Verizon phone and save yourself a lot of hassle. Get a G920V, its already flashed with Verizon Codes to access their LTE Network from the Samsung factory (Hence the V is specific for Verizon). Verizon's sales staff might not even know what a CDMA phone is so would you really want them to reprogram it??

VicFreeze and MindTricks sound dead on in there advice. One thing I am pretty sure about unless someone corrects me is .... even though Sprint and Verizon are both CDMA, they operate on different frequency bands which is probably why your getting the 'R' for roaming. CDMA Workshop has the ability to change the radio frequency. I think the two companies also encrypt or code their voice and data traffic and you need the software flashed that has their specific decoders or encryption software for the device to work on their system. I am not sure if the specific radio software changes any of this or not. I am not even sure is CDMA Workshop is compatible with newer Samsung phones now as two years ago I programmed my Sprint HTC EVO 4g to work on my Virgin Mobile talk and text plan without much trouble but have not been able to get CDMA Workshop to connect to a Galaxy Grand Prime as of late. What I did two years ago was easier since Virgin runs off of Sprint Service Towers. Having a ROM compiled for Verizon may help but things have changed. What I did with the EVO two years ago ..... the ROM had Sprint radio files compiled with it. I am not sure if some of those files are separated in the system now on more modern devices as ..... back two years ago Sprint was EVDO and not their LTE uses a SIM card to work. So, things have changed and keep changing and evolving. One thing is sure, is almost every year Service Providers along with device manufacturers are changing what they do and how they do it.

That's what everyone would love to do but at times proves more hassle than what it is worth. this is why there are sites like Swappa and eBay where you can sell your phone for close to competitive price and pick one up a device that is a comparable condition for the service provider you want to swich to for about a break even price or not much more out of pocket.

I dunno if this thread is dead but process should go something like this.... flash factory binary firmware checking "auto-reboot, nand erase, and F.reset" options. Once it boots enable developer options and oem unlock and usb debugging (then do a factory reset from settings menu). Then you can flash the CSC from Verizon stock. Placing VZW .pit file in appropriate section. Then you can flash the BL,AP,CP files from VZW rom. Personally....this seems like alot of unnecessary work with a great chance for missing something. Might be better to root sprint device and manually install vzw modem files, apns.conf, prl, telephony.db.....better yet why not just flash a custom rom from twrp. thats just one zip file in twrp.

I don't know what I've done differently, but I currently have and use without any problems a Sprint G920P on the nations most reliable network… Verizon. I can tell you that I didn't have to jump through all or any of the hoops that others in this post have outlined. I will tell you what I did ; Flashed G920p with Bigdaddy PL3 Aroma V1.x ,TWRP-3.2.1.0, SuperSu-v2.82, and 3.10.61_Stock_Modified_Kernel_By_Aurora_Rom [email protected]#1. Phone has been unlocked by Idonne apps. I believe that last bit has a lot to do with my success. there is a setting in his app if the phone is to be used on a CDMA network or a GSM network. And not to discredit the person that discouraged you from having a Verizon employee help you but it was he that figured out how to make Verizons system find my phone. Not sure exactly what he did but I saw him take his company phone out of his pocket and scan the sticker on the back of it into the system saying "we will just make the system recognize it". Voila, worked perfectly and continues to operate without flaw on their network. I do get a roam "R", but checking settings indicates that I am not roaming. I live on the border to Canada so it is to be expected, but not the case. As far as Network, device says Preferred Network instead of Verizon. It could say your name for all I care as long as it works! Hope this sheds some light on it for you without having to make all of those unnecessary changes. One last note.... the salesman did say that mine is the first Sprint Device that he has seen on their network.... I guess that makes me special huh? Lol...

SM-G960F/DS on Verizon in the US

Hi all,
I have in my hands an unopened G960F/DS. I was considering this phone to replace an old model, it's long due. I thought I did my homework and was able to determine this phone worked on Verizon in the US, but a serious note on the box and further research suggests I may have been wrong. Although it would be nice to have new hardware, I am replacing the old one almost entirely out of a desire to flash a custom ROM on it. I was under the impression the lack of CDMA support wasn't a big issue given that Verizon (and everyone else) is phasing out CDMA and the phone still had LTE. Thus my choice of the F/DS. I am informed that opening the box and returning the phone will incur a charge, while keeping the box sealed and returning it will not. I am trying to decide to continue forward and test on Verizon's network here in the US or just return the thing, the choice lies in compatibility with this network. So now I get to play a guessing game.
I find myself in 4G LTE areas most of the time. I want to use data and make voice calls.
This 2-post thread suggests not much can be done:
https://forum.xda-developers.com/galaxy-s9/help/sm-g960f-verizon-network-t3856443
This guy demonstrating slower speeds, which I'm not too concerned about, but also HSPA+ in an area he usually gets LTE. In the video description he says after applying a software update it works 'fine':
https://www.youtube.com/watch?v=pkNXCK2iVO8
This site lists some band compatibility but doesn't say anything about not being able to use it with Verizon:
https://apn.gishan.net/en/apn/verizon/samsung-galaxy-s9
This site also lists band compatibility but warns about Verizon's strict device policy:
https://www.frequencycheck.com/carr...e-samsung-star/verizon-wireless-united-states
Is there any hope to use an unlocked S9 on Verizon in the US? I see this going one of several ways: 1) Everyone works out and I can make calls and use data and there are no issues and rainbows and unicorns 2) Data in certain places, no voice because something something "VoLTE" 3) Absolutely no data/voice whatsoever 4) I switch carriers I return this piece of junk and buy a phone that works. (might coincide with 2/3)
If I end up with (4), how can I avoid this issue in the future? I spent some considerable time deciding on this model, which has the features I want and an unlockable bootloader. Will the S10 have this issue? What about the Note 9? I apologize for the noobposting, and if I missed a thread that answered this question. Thanks for any help you can provide, I sincerely appreciate it.
Edit: This thread asks a similar question but isn't specific and neither are the answers:

I have been using a G965f/ds on Verizon Wireless.
VoLTE, vowifi, text, and data work after rooting.
Having done a speed test with a U device and on the g965f/ds, the speed I can receive seems equal.
I haven't had issues with making LTE calls in my area.

Thanks for the feedback. Are you based in the US? How did you activate the phone? I found instructions on LTE activation here:
www . verizonwireless . com/businessportals/support/how_to_use/activate_4g_lte.html
And an IMEI checker, which fails when I enter what I find on the box my phone is in:
www . verizonwireless . com/od/prepaid/bring-your-own-device/#/checkDevice
Edit: It also looks like they have a second page that checks IMEI (this also fails for me). Can you tell me what either of these pages say when you enter your IMEI?
www . verizonwireless . com/onedp/byod#/

I reside in the US.
The imei of my g965d/fs failed when inputted in to their system;however, the SIM is all that's needed for Verizon wireless to work on it. Initially, though, you might need to insert the SIM card into another imei Verizon wireless compatible device only to allow the system to have that imei in the system for your number. Since, you already have vzw, I'm assuming you already are activated on it with a device, so moving sims is the next step.

Thanks for your input. Anyone else have experience with this device on Verizon's network?

I could have written this exact post.

I am trying to do the same thing with the same model Note 9, SM-N960F/DS. I was told by Verizon Level 2 tech rep that simply installing an activated SIM would make the phone work, obviously 4gLTE only since there are no CDMA bands. He checked the 4 bands Verizon uses for their 4gLTE and the F/DS model has all 4 of them.
I am in the same boat as you though. IF I try it and it doesn't work I have to return and lose $125 or switch to GSM network (AT&T or TMO) I am also trying to decide whether to take the gamble. This Level 2 Tech guy didn't mention anything about having to root the phone.
I would also like to know about the advisability of attempting this. I thought I read somewhere that this phone won't have any warranty in US anyway but I am not 100% sure about that. Sellers seem to want to gloss over that issue.

I'm very very interested in this

to put this to bed, you cant use any F galaxy phone on verizon and get full usage. vzw is a CDMA based carrier whereby voice is transmitted primarily via CDMA and data over GSM (which includes voLTE, obviously). The F model do not have CDMA radios in them. You CAN get data to work and therefore voLTE as long as you can flash the vzw CSC to get the phone to install the voLTE app. Long story short, dont try it. Its a fruitless endeavor. I mean, do what you want, i guess, but dont expect for the F to work well, or at all on vzw. There is nothing anybody on xda or anywhere can do to alleviate that.

I had straight talk using Verizon towers on note 8, my note 8 broke, I missed flashing custom ROMs, I bought a note 9 n960f, read online it would work too. I inserted sim. Did not get data or calls. Flashed custom ROMs found a lineage is rom that worked with data for like 2 min then quit. I kept Singapore rom csc stock radios I guess from Singapore, guy on here said he flashed Singapore stock Odin flash and ended up making his work but didn't work with my straight talk Verizon sim. My buddy came over and he uses visible network on Verizon towers we popped in his sim and it worked flawlessly on stock Singapore csc/flashed custom rom from xda. I switched, it's cheaper, it works and first month was 5$ no fee to transfer my number over. Visible is great, join a group and it's 25$ a month.
