baseband question - Sprint Samsung Galaxy S III

hi i was wondering if i were to get a gs3 and use custom roms do i have to worry about losing service with sprint or do i have to update the baseband? if i do lose service can i fix the baseband or something? i'm asking this because i had a metro phone once and i flash it to another rom from another phone and i couldn't call or anything and i had to take it to metro and i paid $30 and i don't want that to happen to the gs3 that i want to get.

No your service won't be affected, the only issue you could run into would be if you flashed a Rom for another carrier on your sprint phone, however if you did that you would have a lot bigger issues than just your sprint service. Stick to the sprint roms section and you won't have any service issues.

Qwest HTC mogul to Sprint Switch

I have been working on changing from a very poor provider to a better one and want to use my very expensive Mogul on the sprint network. I have been wondering around the web for infomation but most of the steps unclear. Do i need to unlock the phone and flash the sprint rom, relock the phone and get sprint to accept the new esn? I think that is what has been said but not sure.
can anyone help?

flash gs3 from us cellular to sprint

So i bought this phone for cheap brand new in box from a foriegn national that purchesed it outright when they got here no contract ( they didnt like it and bought an iphone 5 days later and now i have it). hoping i could flash it over to sprint and upgrade from my e4gt so i can use the beautiful lte in the area.... yeah Rockford. but im currently struggling are there any tips that you guys have or am i screwed...
heres what ive tried. so as i got it i turned it on and it was on 4.0.4 with full signal and working 4g. i used the rooting method that is posted here for sprint gs3's as there isnt one specific for us cellular phones. flashed back to a us cellular kernel as it would boot but claimed no sim was inseterd and boom worked and had root.... then rebooted in recovery and tried to odin a sprint stock rom... failed throws errors. rebooted in to recovery cwm 6.0 and tried to flash some sprint and us cellular custom, stock, and stock modified roms fails checks every time and wont flash. i know 99% of the hardware is exactly the same so it shouldnt be impossible just looking to get this on sprint ... now i have odin the lastest stock update for us cellular just in case it really isnt worth it so i can sell it.... yes i have reset the flash counter and the device says normal device state not modified so that shouldnt be an issue.
on another note my imei number is only 14 digits... isnt it supposed to be 15. when i try and activate it. (assuming i CAN get it flashed to sprint) wont that be a problem. and btw it is the same digits on the box and ive even done the conversion from the meid-dec number and it gives me the same 14 numbers
I don't think USC uses the same LTE bands as sprint so even if you got it working it would be physically impossible for it to connect to the sprint 4G network. May be better off to look for someone to trade with you, or sell that one and buy a sprint version.
http://www.phonescoop.com/carriers/carrier.php?c=12 - according to this USC is on LTE 700/1700, while Sprint uses LTE on 1900.
Damn well it was a nice thought.... Any one want to trade.. Lol well thanks

Thinknig of using Sprint GS3 on Metro! Questions!!

Hi,
I have a Sprint GS3 running 4.3 stock that I am contemplating bringing over the metro. I have a few questions for the experts here:
1. Is there a stock Metro pcs rom that I can load on this phone? Purpose would be to automate things like update PRL button to work for metro, Visual voicemail to work and remove sprint bloatware and use metro bloatware (ha).
2. Phone seems to be fine with talk and text but no data. I have looked at the guides over here but so far, no go. Anyone can help me find out what is my SID??
Thanks

T-mobile purchased them a while back. They quit selling CDMA phones last year and will discontinue support next year. I'm sure CDMA coverage with metro pcs isn't much better than Sprint right now either...plus, how much will they support existing towers? And doesn't Metro PCS 'flash' your phone for you? I thought it was one of those places. You should visit a store or look online regarding this.

Need Help Getting Sprint Network on Verizon Note 2

Okay, I'm sure the information is all out there, so before I get told to search forums or google, I have. My issue is that I'm just having the hardest time putting all the scattered information together and understanding it. There's too much information to decipher whats needed, accurate andd up to date for my situation. So I was wondering if someone whose done this before could just give me the straight to guide.
I have verizon, my girlfriend has sprint. She broke her S4. I have an old verizon note 2 that is unlocked, rooted, custom recovery and on CM11.
What I need to do is get it on the sprint network and get her service switched over to it.
I know it has something to do with APN settings, but there's so many different ones whether it's for internet and MMS. I basically just want her to be able to use it to make phone calls and maybe regular texts. I got all confused when I saw things dealing with PRL and what not, so I don't actually know which things I need to make this work.
I put the sim card from her S4 into my Verizon note 2 and opened the access point settings under mobile network. There are a bunch of sprint ones in there now, I don't know which one to choose. I tried the one just labeled "Sprint" and then rebooted to get the APN settings to switch over but I still have no service to try and activate the phone.
So could someone please give me a simplified walk-through of putting in sprint's settings on a verizon note 2. I tried flashing a Sprint CM11 rom but it failed. So now i am going to try flashing a sprint touchwiz rom to see if that will make all the necessary changes for me.
Update: I Just finished flashing jellybomb touchwiz rom, it flashed but wont get into the phone setup, says there's an encryption error and the phone needs to be reset. I did that and it still does the same.
Thanks in advance guys, I've flashed a lot of roms, I've just never switched my phone to another carrier before.
You can't activate a non Sprint branded phone on the Sprint network. Period. The esn is not in the Sprint database and even if you wanted to use the phone strictly for traveling internationally, The sim card from Sprint will not work in the Verizon phone for the same reason. You'd have to "clone" the phone/esn and that is completely illegal. I would spend my time on craigslist or Facebook and try to trade your Verizon phone for a Sprint one. That's what I would do.
FYI . Verizon phones are actually in demand due to the much larger customer base so making a trade for a Sprint S4 or Note 2 should be fairly easy. But MAKE SURE you check the ESN with Sprint before making a trade because a blacklisted esn phone can NOT be activated and you will be SOL.
So only networks like at&t and T-mobile will work on my Unlocked verizon phone?

If you're referring to your Verizon phone being a "world phone" which does in fact have a sim card and gsm network capabilities, then technically yes it would perhaps be possible to get it to work on AT&T or T-Mobile onl;y but it would be very difficult and time consuming to unlock the sim portion of the Verizon phone and hack it so that it would not be rejected by either network due to the ESN. You'd have better luck trying T-Mobile because they seem to be more lax with unbranded iPhones etc on their network. But in all honesty you would be better off trading your Verizon phone especially if it has a clear esn and getting a phone that's ready to go with no headaches and fully functional on the network.
thanks for the replies

[Q] Porting rooted Sprint G2 to Verizon

First, my apologies if this subject is already covered. I couldn't find anyone with a similar situation.
I have a Sprint G2 that I rooted and it is running CMod 11. I want to switch it to Verizon. I tried taking the phone to the Verizon store and they could not activate it for Verizon. I assume the phone is unlocked however because it activated just fine for Sprint and the Sprint guy told me that's an indication of being unlocked. True? Not sure.
The Verizon guys told me that I need to hack the radio frequencies of the phone before it would work with Verizon. I don't know where the settings are for this though. I already tried the trick of deleting 'Spr' out of a certain system file and I effectively bricked the phone. That didnt work and luckily I was able to revert to the stock rom.
My question is this: Can I get the phone to work with Verizon simply by flashing Verizon CMod to it? Or is it easy to find the settings for the radio frequencies that I need to change? Do I get any data once all is said and done? I don't look forward to unrooting and restoring the stock ROM JUST to hear Sprint say "Oh well we don't want to unlock it for you."

The G2 is only compatible with Verizon's 3G network. I doubt our radios work on the Verizon variant for LTE. Also, the IMEI would need to be whitelisted on Verizon's database. There's no other way around it. Better off selling the LS980 and buying a VS980 for Verizon.

1) no because the IMEI isn't in verizon's database / white listed
2) hardware for the radio is different then verizon's and you will be unable to get lte at all from it.
3) I would just restore to 100% stock (tot) and then sell it and then buy the Verizon version
i have inverse issue
well i bought a verizon variant, only because it was the only one with next day air delivery... I didnt do any research other than seeing that they had the same model number of 980 i figured a radio change and maybe rom change. i tried flashing a sprint rom on it it wont finish the install. do i need to get a sprint sim?
i might be interested in trading that sprint g2 for my verizon g2
