[Q] Diferent Carrier ROMs on AT&T

Hope I dont get flamed for this but i guess getting flammed on the internet is better then messing up my girlfriend's phone . I have a Sprint GS3 and all the ROMs on the forums over there are made specifically for Sprint phones. I'm just curious as to how it works having AT&T, Rogers, Bell ect. in the same forum? Do all ROMs work for all carriers in this forum? Should I only be flashing ATT ROMs? Im nervous to have her flash something and mess her phone up...I just did the no trip root method and bumped her up to Jellybean. I'm glad y'all finally got some JB love over here! Any tips or advice on what not to do would be appreciated.
Thanks
Edit: Also see people having issues with loosing their IMEI...how are people doing this? Looks like its mainly from installing custom ROMs... Looks like you can back up your IMEI, but what are these people doing to have this happen to them because I'd like to avoid that also...

really...nothing?

No i understand that... My girlfriend has an AT&T GS3 that i just rooted for her. I was wondering if theres anything i have to worry about flashing Rogers or other carriers listed in this sections development forums? I've read something about changing APN's and other stuff that is foreign to me being on Sprint.

if it's in this section, you're most likely safe to flash it.
as for the 0 IMEI bug/glitch/thing... that's just a random thing, there's really no way to know if it'll happen the next time you flash a ROM. you just have to take precautions. backup your IMEI. if you flash your first ROM, and your IMEI is there, try to stick with that ROM.

Appreciate the response. Damn... so now every time you flash a ROM you need to not only make a nandroid but also back up your IMEI? also... i don't have an ATT GS3 in front of me...How hard is it to change your APN settings? I heard you need to mess with that sometimes if you're having LTE issues. We don't have an option like that on our phone

once you backup your IMEI, it's backed up. just don't lose your backup. so make a backup of your backup.
as for APN settings, that varies as well. it all depends on ROM, location, signal, provider, etc. but it's rather straight forward. go to your network settings, and you'll see a menu for APN. you don't need an ATT phone to see it.

Sorry didnt understand your question...
Yea hardware on i747 and i747m are the same therefore you can flash the same roms on each device. All you have to do is flash the correct modem and fix the apns for your carrier att, telus etc

[Q] rooting phone?

ok before you say its in the wrong section hear me out. I got a s3 that is from tmobile but unlocked it to use on att. now to root it would i do it from the tmobile forums or the att forums? i just dont wanna screw it up.

I believe being that its unlocked, and you are running att software on it, you can root it with the att guides.
When you root you are not changing anything you are just pushing on CWM and SU not system files are being changed.. when you flash ROMs you may want to use the ATT roms because the data and system files being use to pull your service are for the ATT carrier and it might interfere with the sim card.

I don't think the above poster is right. If you bought it from T-Mobile, then it may need the T-Mobile software regardless of which network you are using it on. Someone with more experience may be able to attest either way, but I think I am correct in this. If I'm not, I'll learn something new!
EDIT: I think you need to use the T-Mobile ROM, but you could root it via ATT guides as long as you are using the proper ROM. (Like, don't use Mr. Robinson's ATT JB ROM to root you T-Mobile phone).

to play it safe, i would follow the T-Mobile guides and ROMs.
i have an AT&T version that is unlocked to work with T-Mobile, but i only use the AT&T related stuff.

[Q] I need help unlocking my Spring Galaxy S4 mini SPH-L520

So, I'm a total beginner with regards to understanding how to mod your cell phone, but I am tech savvy. I've spent the last week of my life attempting to understand how to Sim unlock my Sprint Samsung Galaxy S4 mini Sph-L520 so that I would be able to use a prepaid Straight Talk wireless card with it. At first, I thought the process was going to be rather simple. I thought I could just buy a code online. Turns out that this phone isn't a GSM phone, so this type of unlocking isn't possible. I next heard as tip about getting my phone flashed, but apparently flashing is just installing another operating system on your phone. Though I could see how that might be able get around the Sim Unlock, if possible I would like to keep this stock OS. Also, I'm not certain if flashing my phone would automatically enable me to use another carrier. I then learned what rooting was. Though I now understand that I could simply use Kingo to root my phone, I don't know how that would allow me to use another carrier. So i've spent my last week or so understanding all this new terminology, but I still don't have a definitive answer. I really want to thank this board for existing because I've learned a tremendous amount just reading these threads. So if anyone could help me out here that would be great! :laugh:

I did contact sprint, they said that the phone wasn't stolen and that everything was okay. They then transferred me, but told me that they could only give me the msl code. Is that what I need? Would that carrier unlock my phone?

Does the phone have a slot for a SIM card? If so you could try following this thread step by step. Not saying its going to work but its worth a shot. Its also going to depend on what version software your on. You could always pay $30.00 and get a code from CellUnlocker.

I'll attempt it, but the method described is for a regular Galaxy S4. My phone is an S4 mini, would there be any difference?

I attempted this method, and it didn't work. The phone would not let me flash that rom with odin. It failed every time.

All you have to flash is the modem but that will probably fail also since its not for the mini. You have to find a way to get into the service menu for the mini and then it would more than likely work.

I have also tried:

My baseband is L520VPUAMK1.
Any help would be highly appreciated,

galaxy s4 mini sph-L520
hello
How to convert galaxy s4 mini sph-L520 in gsm for France?
kind regards

International/domestic sim unlock
The GSM portion of the s4 mini can be unlocked .I'm more than sure of it because I have a friend who has his own method .Look up randy unlocks on ebay.He can do it remotely and will call you on the phone and it only takes thirty minutes. I've unlocked plenty of regular Sprint s4's myself ,that process is very easy.The s4 mini would be too if you could find the modems anywhere.He has never told me how he does it but get ahold of him.

Can anyone help me ? Can you back up your radio.img from your unlock phone and send to me ?

[Q] Sprint SGS3 flashed to PagePlus = Sprint or Verizon roms?

I have recently acquired a Sprint SGS3 SPH-L710. It was still original stock at 4.4.2, never rooted. i flashed the n2j stock rom through odin, and then I had it flashed from Sprint to PagePlus and it is working okay (still need to get 3g going) Then used cm-autoroot and installed twrp (debating on installing philz). Now the phone is ready for some rom action.
My question is since this phone is a d2spr, but flashed to PagePlus (Verizon), would it be safe or better to install a d2vzn rom vs d2spr rom?
From my research, there are settings in the roms that are molded to a specific carrier. If I am on Verizon, I do not want to install and have Sprint related settings (buildprop?) and apps, etc. Then flashing a Sprint SGS3 to Pageplus vs a Verizon SGS3, Sprint must be set to NV only, and other posts and forums (on xda and howards), I have read said this nv setting could be changed when flashing a rom, which would break the PagePlus flash. But if I install a d2vzw rom, everything else would be molded to Verizon, which is great since I am using a Verizon network. I suppose it depends on how much molding is being done and what exactly. Then of course, I do not want to brick the device flashing the wrong version. If the roms were only listed as d2lte, I wouldnt mind as much, but I have noticed some roms do have a Sprint version and a Verizon version, but I can not locate the details to compare the differences.

Flashing a d2vzw build will not trick the phone to think it is a vzw phone just more chances of you ending up with a brick.

I am now having a problem updating the APN in any 5.x rom, says not enough permissions. I tried a handful of APN apps on Google play, made them system apps, etc. it never saves or changes the apn settings. I can change and save APN in KK roms just fine though.

Did you try on WiFi it could be cause not picking up data connection
This is why I stopped flashing cdma phones to alternate carriers I had a epic4g on cricket pita if I didn't have the apn fix

I hear you and agree 100% with flashing to alternate carriers. I would not normally do this myself, but considering I got this cell for free a couple weeks ago, I figured I might as well deal with the hassle and make the best of it.
The only problem is that I still haven't found a 100% fix. I been flashing 4.4.x roms and 5.1.1 roms trying various APN settings, apps, changes, tips, etc. Nothing seems to stick or crash when attempting to change it. Trust me I been digging all over Google, XDA, and other various droid forums.
My carrier is PagePlus/vzw, and I can not find a PagePlus APN flashable file, hmm maybe I can come across a generic Vzw one, otherwise I know the settings to put in to create a new one though. This is why I was inquirying on flashing a Verizon S3 rom in the first place. Hopefully I can come across something soon.

When I get off work I'll try to help you out

[Q] HELP, NEED OE2 or OCF baseband

I'm doing some testing and other stuff and I need the baseband and modem in a flaahable zip format for use with twrp should I screw up. Can anyone plz help? I have the g920p and ill be testing the g920t roms. Just came back to sprint this week for service hehehe...... so I'm looking to get some potential new ROMs for our devices either by port or whatever.
Sorry if this is not the place for these kinda questions but I'm an impatient bastard and I don't have time to scope the web for a proper placement for these questions, wth all respect. please and thanks for the help.

I've gotten the tmo roms to boot however...
However I need the baseband for our s6 to have service and,the like.....can someone, anyone get me a twrp or flashfire flashable baseband for OCF or OE2? I've looked and looked and can't find a thing. I've tested a couple tmo roms and yes They boot up and all is well, except no signal, no baseband or anything of that nature. In my past flaahing adventures, I know flashing a baseband will at times fix,the lack there of. Help me plz and thankyou.

Wouldn't this be a kernel or rom issue? Generally, custom roms don't touch the baseband, only carrier OTAs.

Its a modem/baseband issue. It says,unknown baseband and all that stuff and the other radio like stuff is gone also. I believe a,baseband being flashed would resolve this issue. Everything else works like a charm.

So you're flashing GSM ROMs...for a CDMA device...it's not a baseband issue...it's a ROM/kernel issue...
Sent from my SM-G920P using Tapatalk

Well I'm flashing every kind of rom. I REALLY,would just like the damn base and/modem please. I'm flashing all roms and the baseband and imei is broken on GSM on the cdma only the baseband is broken. This request of mine shouldn't be a matter of interrogation....more a matter of helping someone out who would like yo experiment and possibly find a way to run any rom on our devices. Be its cdma or GSM more or less the g920f as its global the the g920v/I/k roms or whatever is cdma.

No no sir that isn't what I'm seeking.....I require the modem so I can experiment with other roms. I need the modem.bin or the modem. I need this desperately. I don't mean to be rude but this should be simple to acquire from a well known and well experienced dev or someone like a dev. Can you or someone please help?

Djvoleur, i too have a sprint s6 thats gsm unlocked and ive tried plenty of stock/rooted kernels for our device with tmobile, att, verizon, sprint s6 edge, and even international cooked roms . Most of them boot when using your kernel . Theyll work with vkernel or unikernel, but as he was saying, although he was rude, the baseband is always unknown. No signal, sometimes you wont even see a X for no signal. Do you have any ideas i could try ? Ive got plenty sprint s6 phones to try this on and not worried about a brick. I know the risks. I titanium backup restore my personal phone nearly 3 times a week to figure this out. Not enough people bounce ideas off one another in this forum

Have you tried a note 5 rom? I would assume the issues from a note Sprint note one wouldn't be the same as the connectivity settings would be the same. The issue would probably be more of a hardware/programming problem. At this point, I think it would be an easier port since our device isn't as similar to the international device as we once thought it could be.

Never tried note 5 rom . I dont think that'd work without a port of device drivers n such
