Flashing help. - Sprint Samsung Galaxy S III

I want to change my carrier. I currently have sprint. What are my choices and what are the drawbacks of each? Will I still be able to use MOAR ROMs? Ive never done this before any help would be greatly appreciated. Thanks.

Page Plus prepaid is great it uses Verizon network. granted your limited to 3G but man their 3G is crazy fast compared to Sprint. I had both my phones Flashed to Page Plus by a authorized dealer Evo 4G LTE & GS3 and I don't regret it. Everything works data/mms/sms. Now granted I had to use Verizon Messages app off Play Store to be able to send mms.
Now with in the last month or so Straight Talk offers service for CDMA phones I'm wanting to try that route next Friday and see how that works. I unlocked my brothers AT&T GS3 and activated it on Straight Talk Unlimited and hell he gets LTE.

Thank you so much. What Roms Will I be able to use after I flash? I use MOAR now Can I still?

Does anybody know if after flashing can I still use any S3 roms?

Rooted and CWM my epic 4gt, now how do I flash to straight talk and activate?

My ep4gt is rooted and CWM, but where do I find the rom for straight talk? I assume I need a rom to make this work on the ST unlimited plan.
Once flashed, how do I activate on ST?
Sorry searched couldn't find this answered.
You can't. Straight Talk uses T-Mobile's network which is GSM/AWS, and requires a sim card. This phone is CDMA only.

Straight Talk is CDMA (through Verizon) And no it hasn't been/ cannot be done as far as I know.
ST uses ATT, Verizon, and t mobile afaik.
There are mulitiple services on ebay offering to flash your cdma phone over to ST on the verizon network.

It looks like sprint changed some 3g passwords after the iphone release. thats why my speeds reverted to 1X. You can update the passwords but if you didnt flash the phone yourself then you need to get it back to whomever did it and they can update it. I actually just took my eg4t and flashed it to straight talk wireless instead. $45 unlimited everything(although they are supposedly cutting people off that use more than 3-5g per month) It runs off Verizons towers so my speeds quadrupled over sprints crappy 3g speeds."

I PM'ed him,no reply yet as to if there is a way to do this without paying to have this done.
Id save over a 100 a month if I could switch my lines to straight talk. Im kind of interested in this also, but its something ill want to do myself and not through ebay.
For Android phones, Straight Talk uses Sprint. They signed a contract back some months ago. They are not ties to a specific provider and will use what makes sense for them, so it could change over time.
Well these phones when flashed use the verizon network. There are lots of youtube videos where they call some number and it tells you the provider.
So i'm seeing that this is a paid for service only (to have phone flashed to ST)
Interesting. 2 people I know with ST, and both phones have SIM cards. Granted, both are clamshells, but good to know.

I bought two ST phones last year, the Samsung qwerty slider, and the one that looks like a blackberry. They were both cdma and ran off the Verizon network. They had bars where my sprint phone did not. I guess different regions use different carriers to piggy back on. There is no T-Mobile coverage in a 10 mile radius where I live.
Here you go:

I'm sure Straight Talk is willing to use whatever makes the most sense for them so I wouldn't be surprised if they switch stuff around over time.
Maybe this process goes around that? But I have confirmed that these phones do work on the vrz network.

how did you flash yours?
I have my ET4G running on prepaid Platinumtel. You can take any Sprint (Android is easiest) phone and "hack" it to run on any Sprint MNVO network easy (with some diligent research on the web) such as Platinumtel, Virgin etc. I can't say how here, only that it can be done

Do all the Sprint prepaid spinoffs (Boost/Virgin et. al.) offer unlimited data, or is it capped/throttled?
Sent from an Android-powered HP Touchpad.
Update:
You have to start the port process 24 hours before the idiot starts the flash process. It's not really a flash though.
It uses the verizon towers, no question. You can change around your prl's to determine which towers you wish to use.
So far, very happy with this

Leaving sprint, want to keep my E4GT, what are my options?

Sprint has sent me a termination letter for excessive roaming and cutting me off July 3. This is probably for the best because my new job has 0 sprint coverage (deep inside a building) and i've been roaming on verizon for the last 2 months while at work. Anyway, I do love my epic 4g touch and while there are other phones that are now "superior" I'd prefer to keep it if possible.
So my quesiton is:
What other providers can I use with an E4GT, and how much work does it take to switch? (Flashing, odin, etc). And also, what would I lose in terms of 4g/3g/MMS, etc I'd prefer prepaid services like boost or cricket but of course, I don't know if they have coverage where I work but having all options on the table would be helpful!
Thanks in advance XDA!
I think it can be flashed to metro pcs, boost mobile, and virgin mobile. There's a couple threads around here giving you exact instructions in how to do so so check those out. I believe you'll lose 4g except with metro and everyhing else should be good.

Virgin Mobile is launching their 4G WiMax service at the end of the month. Something to look into.
Page Plus (VZW) is really your only option as the rest of the MVNO's listed here are Sprint. So same/no service.
Best off selling it and getting a new phone honestly.

I thought it varied by region for the reselling companies?
You can flash it to anything cdma. You would need a donor phone though. you would most likely only lose wimax.

Ok time to give it to you raw..... (No Homo!) This is what you need to do my friend, go to google type in prepaid services and your zip code. See what pops up for your area then make some phone calls to them and ask them about their service in your area. Secondly you can then go to all of their respective sites and check out the deals. You may find like mentioned that selling the phone and purchasing lets say a T-mobile branded Galaxy 2 and using Simple Mobile may work better for you.
I understand trying to ask your fellow members but honestly what we are going to tell you I am sure you already know. Lastly, check with others in your area and see if one of the other big 3 work extremely well in your area that you desire the coverage and then check out their prepaid services
T-Mobile - Simple
AT&T - H2O
Verizon - Page Plus
Sell your phone for $250 purchase another Galaxy 2 for around $300 or work a trade out with someone.... Time to do some homework my friend... Get close with Google...
Happy searching!
if u get good boostmobile covarage in ur area then flash it to boostmobile
So it seems the only cdma carriers that use/resell verizon are pageplus and of course, verizion. Can an epic 4g touch be flashed to either of those?
I currently have my epic 4g touch flashed to straight talk 45 unlimited on Verizon coverage way better than sprint faster data far as 3g goes around 1.5mb a sec and signal is awesome

Awesome! How hard was it to flash it to straight talk? Any links would be helpful! I've never done a flash to another carrier so i'm not sure how hard it is exactly. So so far to get verizon coverage I can use:
Verizon resellers that work on an epic 4g touch (flashed):
Page Plus
Verizon Prepaid
Straight Talk
Sprint resellers
Boost Mobile
Cricket
US cellular?
MetroPCS
Virgin Mobile
If any of that is wrong let me know.
I flashed mine to Page Plus. Followed this guide, talk text and data work, but I am still working on removing the hidden Sprint APN settings to get MMS working.
It might seem a little intimidating, but it was pretty easy.

If you dont have a donor phone thats ok, but dont expect to get full 3G speeds without it. If you use the vzw password, you get 1x data. At least I am not getting raped on the monthly fee, so I can save up for the S3 and will probably move to straight talk.

question is, if he had to roam at work because Sprint obviously did not have tower close enough, then wouldn't Boost be a waste of time because you can't roam with boost, or virgin mobile for that matter, meaning he would just not have service where he works.

Thanks for that link, its awesome. I will likely go the page plus route though after googling the new phones im on the fence now, lol. The Galaxy note may be coming to t-mo as is the SIII. I don't want to spend $700 on a new phone, but if I can get $275 for my E4GT i'd be willing to pay maybe $500 and just eat the difference. I have until about June 20 to make my decision. At this point it'll either be new phone or page plus / straight talk flashed E4GT. I am pretty sure sprint doesn't set my ESN to bad on my epic just because they are booting me. If they do I'll be pretty irate.
if 4g is available in your area you can purchase a modem for it (clear wire, time Warner,net zero,etc) and use its MAC addy on your et4g as to still have 4g, I'll edit my post when I'm on my laptop to link to the thread with instructions to do that....

Letter of death workaround...
Have the same issue, you may want to try and port to Google Voice, terminate your Sprint account this will automatically happen once a port takes hold of the account number. Let the account terminate; start a new line of service from one of the big three or back to yellow shortly after.If you love the E4GT, go back to yellow the next cycle with a new bis/indiv. account and port your number back. Not happy or locked into the contract just prl flash back to the reason you most likely got terminated and then go over to big red when the SIII is released. Done and done... you'll keep the same phone if on yellow with little loss, and no ETF...
Can you explain what you are saying more for me? im getting kicked off due to a roaming issue on the 18th (tomorrow) and this is my business number so i need to keep it, however the 2nd line is fine on yellow which doesnt make any sence since its a business share plan so they told me that i can keep the 2nd line but will need to go to another carrier with the primary, dont care for limits on data so verizon seems like my only option but are you saying to take the number back to yellow after switching to another? cause they told me i could try after the new carriers 2 year contract but cant gaurentee ,,,but i thinkk that might have been a wink wink in the conversation from the yellow lady. i wouldnt mind switching to ver. prepay with my E4gt just to keep things smooth for now so if anything can you point me to a thread to do this (preferably wo a donor but i do have an old verizon prepay, its the one that flips both regular and landscape style, so would this one work as a donor, it has been activated before tho....thanks

[Q] Sprint to Verizon?

I've seen some threads that are close, but I wanted to know if I can flash my GS3 from Sprint for use on the Verizon network? I'm not trying anything shady, it's just that Sprint's network has me about at my end, and I was given a demo S3, and man, it's not even close.
So, I have an S3, with no outstanding contract from Sprint, can I use it with a new account on Verizon? Just trying to avoid ending up with a Sprint GS3...
Thanks
No, you can't. I'm pretty sure the Verizon version uses frequencies that the Sprint version can't. For instance, Sprint's version uses 1900MHz for LTE, but Verizon's uses 700MHz.
Even if the radios matched, it wouldn't work because the Verizon one requires a removable SIM for LTE, and that's not an option on the Sprint one.
On the bright side, there's a chance you could do an even trade with someone who has the Verizon S3, so no one has to spend extra money.
Verizon and Sprint use a different frequency between networks, the actual hardware in the phone (radio) cant pick up anything else than its been made to see. Best bet is selling sprint phone and buying a verizon model
Really? My Sprint GS3 was flashed to Verizon with no issues. LTE of course does not work but I knew that prior to flashing. My 3g speeds are pretty good anyway, much faster than Sprints.

[Q] What note 2 to buy next

I currently own a note 2 L900 sprint version flashed over to boost mobile. Right now I have it on ebay. I want to get one I can use with straight talk or other gsm providers. I hear it's easy to get the ATT version on straight talk. I also hear the Verizon version can be flashed over to straight talk but idk why if it was unlocked the apn couldn't be added to use straight talk. If anyone can clarify that please let me know. Also I see different versions for Verizon and different versions for ATT. Please help me in deciding the perfect note 2 for me! Thank you all very much for viewing and any input I may get on this. Also being able to go back to boost mobile might be a plus. Where I go Verizon is the best signal but I'm all done with paying such a high bill and only getting squat for data. Also I would like to add Sprint service sux!
ok, from what I gather the sprint/verizon phones can be used and run on verizon signal. Att and tmobile run on ATT. Anyone know if there's any phones that can be programmed to accept both signals. that would be fantastic. CDMA vs GSM would be the stopper but what about the 4s and it being CDMA and GSM?

Please help with straight talk.

I've been searching for videos and guides but ijust can't seem to find anything but I know it's possible to go from Sprint to straight talk, so I was wondering if someone could be generous and help me with this, I knew I'm suppose to flash it than go buy cheap phones for cloning than update stuff, and I also saw certain roms can actually give you Verizon Lte with certain straight talk 4g stuff. I would really apperciate the help.

I know I'm very late but Straight Talk supports byod even cdma LTE should work too. Check this out http://stbyop.com/straighttalk/ or you could buy the kit at walmart for $65 but if you buy it no money back guarantee. I put in my MEID number and it's compatible.

I believe you are mistaken. I have a Verizon Tbolt flashed to StraightTalk. http://snyderswireless.com/ said they could flash my Sprint GSIII to Verizon or StraightTalk if I wanted, just no LTE. The guy is cool and did my last flash remotely, very informative.
(Sorry if this is an old issue and has since been addressed.)
