Hello All,
I hope someone can help me with this.
I have a TP2 (Sprint) and I need to use it for At&t.
The first thing I did was unlock the device using RhodiumWUnlocker from Olipro (and made my donation ).
I did all steps, and everything went fine. No problems. And it detected AT&T
Then I flashed the ROM with EnergyROM Leo Manila 2.5 WM6.5 v 16Feb2010, By NRGZ28. (File: Energy.RHOD500.23529.Leo_MaxManila.16.Feb.2010.rar) - Still all well, no problems.
Then it went back to stock and could not detect AT&T. So I flashed the Radio Version: 4.49.25.91 from this thread: forum.xda-developers.com/showthread.php?t=549939.
Now I cannot turn on my phone at all - No "touchpro2" screen, no bootloader, nothing at all. The phone doesn't react to any combinations of buttons to turn on or load up bootloader. When I connect the phone to the computer (Vista by the way) the charging orange light comes on for about 3 minutes then goes off. Then I press the power button and the light comes back on, but nothing else happens to the phone.
Please help!!! Let me know what's wrong and how I can fix it, please!!! I'll make another donation to fix it.
Thanks!
I'm no expert but it sounds like you may have flashed a CDMA Rhodium with GSM firmware. I had a quick look and it seems the Sprint Rhodium is CDMA, you should have a look at the CDMA Rhodium forum here:
http://forum.xda-developers.com/forumdisplay.php?f=517
I'm not totally sure of the GSM / CDMA thing because I'm not in the U.S. it's not something I need to worry about.
Good luck dude
Yeah the more I look at this, the more I am convinced this is what has happened.
You used CDMA HardSPL (RhodiumWUnlocker)
Then flashed a CDMA ROM (Energy.RHOD500 ...)
but your mistake was to flash a GSM Radio ROM (I followed the URL you gave and up popped the GSM Radio ROM thread)
I don't know if this is recoverable but searching the CDMA forum would be a good start. You can't be the first person this has happened to.
Thanks for the response, but I am certain I flashed the correct ROM.
*I went to the wingster website
*I selected CDMA ROM's
*Clicked on EnergyROM Leo
*Clicked on Download - Hotfile.com
*Selected this ROM: Energy.RHOD500.23529.Leo_MaxManila.16.Feb.2010.rar
When I flashed this ROM, the phone loaded up without any issues. The only problem was that I could not make calls because it could not detect the AT&T SIM card. So I flashed the radio shown on the post from xda, and the PC said congratulations, everything is complete and good. At this time, the cell phone rebooted and it just never came back on.
Thanks for the help!!
Thanks MadBeef, I will research the CDMA forum.
The Main ROM you flashed was fine. It's the Radio ROM you flashed that killed it, because your phone is CDMA hardware but now it has GSM Radio ROM on it. That's my theory anyway, I'm hoping someone a bit more experienced with CDMA will be able to chime in.
If you can get back into the bootloader somehow, you should be able to flash a CDMA Radio ROM.
I only read the first line of your problem...sprint to at&t...it can never happen. Sprint is cdma which has no sim and at&t is a gsm which has a sim. You better have insurance so you can run over your now "speed bump" and get a new one.

ROM fine.
Radio ROM = BAD.
RHOD400 and RHOD500 are the model numbers for the Sprint and Verizon TP2s respectively. Other carriers also share these model numbers, but those are the big two.
The Radio ROM you flashed however is for the GSM only TP2, not the combo CDMA/GSM TP2 that you have.
Flashing that Radio ROM was a HUGE no-no. Boom.

You should put a little more time into research before jumping in with the flip comments.
1) Sprint does have SIM cards. I've got one in my hand. (No, they're not used in all phones of course, but Sprint does have their own).
2) The Sprint Touch Pro 2 can very well be used on ATT once it is security unlocked and a patched Radio ROM is flashed. To say "it can never happen" is flat out wrong because it's been happening for a few months.
3) The CDMA Touch Pro 2 models (RHOD400 and RHOD500) aren't just CDMA. They are CDMA/GSM/UMTS worldphones, supporting operation in all three modes.
I'm Sorry Gamescan if I did not understand correctly. Does this mean there is no help? There's absolutely nothing I can do to revert this and fix it?
I really appreciate all the help!!
I wanted to reply to Akademik's comment, but I didn't have time. This is not the first phone I flash, but it is the first CDMA/GSM phone. I know this phone is dualmode, else I wouldn't have bought it to use it in AT&T.
Thanks again!

Can you connect to it via a mtty terminal?
I don't know if the SD card flash method would work here. If it were my phone I'd try it, but if it's not getting as far as the bootloader I think the chances are slim Maybe while there is no SIM card in it, give the radio ROM less to do?
Found some CDMA radios here:
http://forum.ppcgeeks.com/showthread.php?t=90342
Sounds like you might be screwed but there's a few ideas you can try. Good luck.

Sorry, but what's a mtty terminal? That's new material for me...
and as Madbeef said, I have no access to the bootloader screen. I'm pressing all possible combinations of keys, and nothing.
Thanks again.

this result is based on shenriquez american flag in his pro. basically saying hes in america using an american sprint tp2 and trying to use american att service.
gamescan, if i said it cant be dont its quite obvious ive done research through trials and also working a phone carrier for 3 years before finding a better job...THIS CANNOT BE DONE. the dual mode in the sprint tp2 is ment for when people travel to europe, they can pop their "european sim" in and be on their merry way. european cell towers accept the frequency of the sprint tp2 and establish a connection. the US towers have "locked out" tmo and att from being used in the sprint tp2. the reason why you found att on connection setup was that your phone was basically saying" yes att is here, but your not connecting". shenriquez i followed the link to the radio you flashed before you got "shut off". you shouldnt have flashed a GSM radio on a SPRINT TP2...you are bricked my dude. you gave your phone a seizure man.

Google mtty (or search for it on here).
Short version it's text based, but it's pretty much the lowest level access that a consumer can get to a HTC device without ripping the sucker open, manually desoldering the flash chip and putting in another.
If you're not getting the tri-color bootloader screen, there is still the possibility of saving it via terminal commands, but it's not straightforward (and depending on what happened it is certainly NOT guaranteed).

Only it can be done.
With the tools mentioned in this here very forum.
Any many people have done it.
Again, you're not doing your research and making claims that are flat out wrong.
1) The Sprint TP2 hardware does support the US GSM frequencies.
2) The Sprint TP2 hardware does not ship with a SIM lock.
3) The Sprint TP2 hardware does ship with the two US GSM frequencies disabled in software.
4) If you pay for the Olinex security unlocker you can easily flash a patched radio ROM which re-enabled the two disabled frequencies.
About the only correct thing said in the post above is that he should not have flashed a radio ROM from a GSM-only TP2 to a CDMA/GSM combo TP2. The two devices do have different hardware so flashing the wrong drivers *IS* a BAD THING(tm).
But, assuming you have paid for the security unlocker, flashing a Sprint TP2 with an updated radio ROM is stupid easy and once you've done that making it work on ATT or TMO in the US requires nothing more than slotting in an active SIM card and switching the phone to GSM mode.
If you don't know the answer to something, please feel free to ASK about it, but don't make unfounded and incorrect statements. When you state an absolute that is false it just spreads misinformation which makes things confusing for other users, especially those new to the device.

Prove your lame theory. Links that sprint gsm will connect to US towers. Even links in "this very forum". Different frequencies dude.
My two cents -- as I am new, too -- but I ran into a similar situation trying to update the radio on my Verizon TP2 due to 1X issues. My phone is unlocked as I was running Mighty but decided to return to stock (6.1).
Note: my SIM is not unlocked. If I understand correctly, the SIM needs to be unlocked to be able to install a radio from a different carrier, like Sprint.
[As a side note: I think these forums use the term "radio" a little too loosely because the program to unlock the phone to be able to flash unsigned ROMs is also called a "radio" unlocker.]
Back on topic: I flashed my phone with and unlocked radio 2.23.00WU and the result was similar to what happened to your phone: it did not turn on, orange light was on.
I was able to flash stock ROM back onto the phone using the USB cord and the phone is back to normal. Even though it was basically non-responsive except for the orange light.
My phone is in working order after the wrong radio incident.
I hope this helps.

If you believe that you're obviously flat out lying when you make the claim of having worked for a carrier for three years, because no one who worked for a wireless carrier could possibly be this ignorant about how GSM works. It's either that or you're purposely posting false information in a lame attempt to screw with the newbies on this site.
The Sprint TP2 hardware supports all four GSM frequencies - 850, 900, 1800, 1900. You can pull up any spec sheet on the model to see that. This isn't exactly hidden information.
Sprint disables the US frequencies in firmware.
If you are security unlocked you can flash one of the two patched radios in the sticky thread in this forum.
http://forum.xda-developers.com/showthread.php?t=578659
Then you toss an active SIM card into the phone and turn it on while in the US. Set it to GSM mode and bam, you're on a US tower.
Your claim is the equivalent of running around screaming "The sky is GREEN because I say it is! The sky can't be blue. That's false!"

The phone needs to be security unlocked to flash a different radio. If it is not security unlocked a unsigned radio will cause the boot sequence to fail. Flashing a carrier provided radio will restore the phone to service.
Security Unlocking means setting the phone to SuperCID. It is different than SIM unlocking.
SIM unlocking allows you to use different SIM cards. It does not allow you to flash unsigned radios.
The Olinex unlocker will both security unlock you (SuperCID) and SIM unlock you (if needed).
if device was security unlocked and is detected by pc, most likely it can be recovered by mtty. unlike my case where device was not sec unlocked but its detected by mtty using usb or serial. bad news is it would be very hard to recover, im doing some jtag research first, at least i found the pins but no pinout.

thats for a radio not rom. find the cdma rom that allows you to use a gsm sim. you cant use the cdma rom over att network...and that link you posted, there are no success stories in it, only complaints. you have no idea what you are talking about. you sit there posting false statements and trying to sound smart with your handy thesaurus. stop posting false statements lame.
MetroPCS does not have this phone listed in it's list of flashable phones.
How might I get this working? If I were to get my hands on a MetroPCS ROM for another android device, is it possible I could piece together a working ROM? Or does anyone have any other ideas?
It's currently set up for Sprint (clean ESN for Sprint, not that it matters much for what I'm trying to do).
....... no
one rom for 1 phone doesn't work for another. it requires work to port
Yep, I got that. I was more asking if there is something I can get from an existing metropcs ROM to clue me in onto what changes to make.
If I reset the SPC, upload a metropcs PRL, and I'm assuming change any wap settings to use metropcs's internet... is that enough? Or is there really more to it than that?

the answer is no.
WiMAX isn't even on MetroPCS. It uses LTE. There is just way too much difference in terms of radios and frequencies.

Ahhh. Thanks for the info. Guess I'll activate on Sprint then. Anything to get away from AT&T right now, service in my areas has been horrible for months.
Metropcs nexus S`
Well obviously the 4g portion of it is different.
Now the evdo and supposedly 3g should work on are where metropcs has it.
Its no problem otherwise you can do everything you can with the nexus, just at a slower Internet speed.
You should probably be able to follow a tutorial for a samsung phone.
Is it possible to get an unlocked CDMA Nexus S so that I can use it with Metro PCS. Which brings up another question, would Metro PCS allow me to use the Nexus S on their service?
Technically, the Nexus S as well as the Nexus S 4G are "unlocked" and can be rooted with no special hacks. I would imagine that MetroPCS can develop their own ROM along with a radio and make it available on their site if users choose to do that. I don't believe there is anything in Sprint's contract which would cause a lawsuit for doing that.
The question is if MetroPCS will allow this phone on their network... it's up to them but I don't see why not, as they don't make money on phones anyway (I think)

Why would MetroPCS make a ROM for a phone that is unsupported? They'd have to go to Google to make a compatible phone in the first place.
Why would they spend money on making a ROM for the Nexus S? That just makes no sense. A radio is also not open-sourced. Radios can only be created by Samsung or Google for the Nexus S.
Get your facts straight
Whoever asked the thread said nothing about ROMs. He asked if an unlocked nexus s could be flashed over to metro which it should be able to.

Hi everyone, I've been a longtime lurker here on XDA for anything and everything I've needed for my devices, but in the six-or-so years I've been on here, I've never had anything to contribute on my own for the community. Today, however, I'm stoked to say that for the small number of people that haven't given up on the LG G3 Vigor, I FINALLY was able to obtain a stock firmware 4.4.2 file in .KDZ format direct from LG.
I, like many others on here and other G3 communities, have struggled for the past few months in trying to keep this device stable, but apparently the Vigor (more so the D725 AT&T variant, since it seems the Sprint LS885 has a little more support, but still basically next to nothing at all for both) is a redheaded stepchild or something since no one I've seen on here has been able to offer anything other an a root method for it, however I can't help but think that was just dumb luck since that root method has been proven to work on to work on ALL the G3 variants. Anyway, after almost giving up on this device after six months of not being able to find a stock firmware ROM file for it, let alone any custom ROM, I tried calling LG as a last resort with not much hope. Lucky for me though, I got a super nice rep by the name of Rachel, who immediately understood what I was asking and e-mailed me a link to the only stock firmware file they have for it - a D725PR 4.4.2 firmware file in .KDZ format.
You may notice that the model number - D725PR - isn't either of the AT&T or Sprint models. It's actually for the LG G3 Beat that was released for Puerto Rico, but it is basically identical to the D725 and LS885 minus the carrier APN settings, and of course no AT&T or Sprint bloatware. Rachel was so confident that this file was what I needed, that she wanted me to flash it while on the phone with her, and if it didn't work and I ended up with a brick, she'd open a warranty ticket to replace it free of charge since my Vigor is still under warranty (as are almost all others I think, since the Vigor was released late 2014.) I used the LG Flash Tool under Windows 10 while on the phone with the rep the whole time, and sure enough, about six minutes and two reboots later, the device booted right up to the LG setup welcome screen. I was told that since the KDZ is technically for the Puerto Rico variant, I'd likely have to manually input AT&T's APN settings for data, but it configured itself and AT&T's APN profile in the mobile network/tethering menu was already in there. Now, my device is unlocked, so I don't know if maybe that's why it configured itself on its own, but if you flash this file to factory restore or downgrade, or remove root and find you don't have your carrier's APN profile in there, just do a Google search for the settings, and you should get your data back.
Sorry this post ended up being a novel, but I'm very happy that I finally managed to score this stock firmware file after LITERALLY six months of it sitting in a drawer, pulling it out every so often in hopes that somewhere online, someone posted the file to finally get everyone flashed back to stock, but nope. I don't see why this wouldn't work for anyone else with an AT&T or Sprint Vigor, but obviously I must say I can't be held responsible if, for whatever reason, something bad happens. I hope this was able to help at least SOMEONE other than myself, because like I said, I've been using this forum for the past six-or-so years to keep up with development and learn to root whatever new device I got, but never contributed myself. This community deserves it, because no one on here has to do what they do, yet they choose to do it all for free, as a public service or something, in order to help others have a better experience with their devices. And for that, I myself am forever grateful. I hope this helps - good luck!

Not meaning to beat a dead horse as I know this thread hasn't seen activity in several months but I wanted to let others know that I took a chance with my D725 running the factory 4.4.2 firmware from AT&T and installed the firmware in the OP and voila, it works without any issues that I've noted so far aside from a particular menu option not being available (the Phone info page when using *#*#4636#*#*). Everything else so far has worked with one additional bonus:
If you attempt to use the factory D725 firmware with T-Mobile's network or any MVNO that uses their network you will not get LTE service - it just won't happen. It frustrated me when I discovered this little aspect because AT&T's firmware only supports LTE bands 1/3/7 for "roaming bands" aka anything that's not AT&T - T-Mobile uses bands 2 and 4 which AT&T also uses but it appears that if you put a non-AT&T SIM in this device (the D725 running the factory firmware) it will not allow connections using those bands 2 and 4.
You also can't even choose LTE using the Phone info page - the option to choose a preferred network type is removed in that firmware (to the best of my knowledge it's not there - I only have my D725 as a point of reference so I can't speak for anyone else and again this is strictly for the 4.4.2 firmware, I won't touch the Lollipop update anytime soon).
However, I took a chance and installed the Puerto Rican firmware just now and voila, with the addition of the T-Mobile LTE APN info (fast.t-mobile.com) and changed the network type under Mobile networks (an option that does not exist in the factory AT&T firmware there either) I've got LTE AWS service now.
I made a post in the "main" G3 Vigor thread with screenshots if anyone is interested:
http://forum.xda-developers.com/showpost.php?p=65081251&postcount=300
I'm already committed to selling this Vigor but I just wanted other D725 owners out there (probably not a whole hell of a lot of us it seems based on hardly any posting activity about our device) that yes, if you're missing out on T-Mobile LTE service with your presumably unlocked LG G3 Vigor by using the factory AT&T 4.4.2 firmware that there's hope and it comes from the Puerto Rican bloatware-free firmware + adding the fast.t-mobile.com APN information.
Have fun, always...
Thank you. I've been looking for a ROM to flash my D725. I will give this a try. Thank s again to TJBilyK and br0adband for this info!

How to safely root after going to D725PR
After following the steps in this post to install the D725PR firmware successfully, I am wondering how to safely root this device.
Background
Six months ago I used the above method successfully to resolve a problem I had with my LG G3 Vigor D725 which I purchased unlocked on eBay. I had been and continue to be able to use the phone network here in the Fiji islands where I live, with either of the two main providers here, Vodafone and Digicel, depending on which company's SIM card I have installed. My problem was that I was unable to enable the wifi hotspot feature in the phone (with either provider) so I could connect my laptop to the internet via the phone. Upon pressing "Enable" (of wifi hotspot) in the phone, it would disappear for 15 secs then come back with an error saying it could not connect with the network due to a network fault. I took it to the best engineers at the mobile phone companies here and they tried everything they could and in the end advised me the problem was in my phone, not with their networks. So I flashed the phone with this Puerto Rican version of the firmware and voila, I have been able to use the wifi hotspot feature ever since. So a sincere thank you for making this available and as this was my first and only phone flash experience and I could never have done it without all the detailed instructions, the link to the flash tool etc. I still have one problem though, I would like to be able to root the phone but I am unsure how to do that without bricking it or undoing the progress I have made. "Root Checker" tells me "Sorry! Root access is not properly installed on this device". Thank you in advance.
Hi,
I was recently gifted an unlocked ATT S8+ (SM-G955U) which I'm trying to activate to my Verizon account. I've read conflicting information about this, and after going to the Verizon store and calling them directly I'm thoroughly confused.
The rep on the phone told me that the phone is "incompatible" with their network based on the IMEI number. From what I gather, the hardware (and model numbers) on all the major carrier's S8+s are the same and simply have different firmware. I've also read that they're interchangeable. Has anyone successfully gotten the ATT S8+ on Verizon? I'm almost feeling like it's something where I would need to jump through more hoops and speak to a manager to get them to do it, but before I did I wanted to get others input. Thanks!
I heard that the phone will work, you'll need to flash the Verizon firmware onto the AT&T phone.
Thanks Richie. Do you think that Verizon is telling me that the IMEI is "incompatible" because I may need to flash another firmware to enable CDMA? Or are some versions of the S4+ really incompatible on their network.
May there be possible success to get them to activate it anyway?

Do you already have an active Verizon SIM card? Like in another phone?

I do not - only because I'm coming from an S4 (which has the larger SIM card). I had to get a new one.

The IMEI thing and Verizon not provisioning your phone to activate on their network is the ONLY obstacle you have.
All the US S8/S8+/Note8 variants are identical and can be cross-flashed to whatever carrier you want. You can easily grab the VZW firmware and flash it on to your AT&T device, fully converting it, however the IMEI won't be in Verizon's system since your particular phone wasn't sold by Verizon.
Somehow get around that and your phone will be fully compatible on VZWs network.

Don't worry about what Verizon reps are telling you because most often than not they are following a standard procedure. And they only Input your IMEI into a service like this one:https://www.verizonwireless.com/bring-your-own-device/#checkDevice
As your IMEI is for an AT&T phone, the brand model has an A appended at the end (as in AT&T).
However, you should still investigate this issue and try the steps recommended by the other guys. You will be able to use your phone with a VZV sim without reaching to Verizon

I have an AT&T S8 + on Verizon's network, had to unlock the phone, I did flash VZV firmware.
Works for me.
Thanks all for the responses! So it does look like I can do it then, but I just need to get Verizon to activate the new SIM. Think if I could find another phone that's compatible, throw the SIM in, activate, then switch the SIM to the S8+ it would work? (Assuming I've flashed the Verizon firmware on it).
Also, I'm trying to find out how to flash the phone properly. I don't really need root, but I'll take it if its easy. Thinking in my scenario, I'd follow this thread, correct?

Yes, if you can get VZW to activate a nano SIM then all you have to do is pop it in your S8+, and it will work perfectly.
You don't HAVE to flash the Verizon firmware, but you'll won't be able to use certain features such as VoLTE and WiFi calling with the ATT firmware, so I recommend it. Not a necessity though.
To change carrier firmware, follow this thread:

Can't help you with rooting. Sorry, I stopped rooting my phones long ago.

This is great information! I'll call back Verizon and knowing all this I have something to back myself up with to at least try to convince them to activate the SIM (if not, I'll find a temporary phone to activate).
Thank you (and everyone else) for all the help!
I was able to get Verizon to activate the SIM and IMEI of the new S8. When I checked my account online to verify, it shows the correct numbers. Unfortunately, the phone is still not able to make calls or connect to the mobile network.
Following this, I rooted and flashed a deodexed stock ROM/firmware that is compatible with all carriers. This made no difference in the issue.
On the status bar, normal reception for my area is shown. There is no data (LTE/3G, etc.) connection, however. In looking at the APN settings, there are multiple Verizon options to choose. "Verizon Internet" (VZWINTERNET) is what is selected. Under the network operators, Automatic is selected. I tried changing it to Manual, but I do not get an option to select Verizon. Only ATT or T-Mobile. Under SIM Card Status, It's says that I'm on an unknown network.
Any ideas on what I could do to diagnose this? Sorry for all the questions, but I want to be able to get this phone to work so bad!
Thanks!
Success! I was about to give up, but decided to try a few more things.
1) To register a new SIM on VZW, it needs to initially go into a VZW based phone to work correctly. Once doing this, I saw some changes:
- I could now see my phone number.
- Verizon was an option under the network operators setting.
This did not solve my problem, however, as I still could not connect to the network. When selecting VZW, the request would fail and say to try again later. So onto the next (and last!) thing I did...
2) Download VZW firmware and flash via ODEN (The Comsey version, but I don't think that matters). I added the BL, AP, CP & CSC (included in the zip file) using the default options. I found this firmware at the below link and grabbed the latest version. The download was very slow for me (I had to run it overnight), but numerous posters stated that they are a reliable source so I took a chance.
https://www.sammobile.com/firmwares/galaxy-s8-plus/SM-G955U1/VZW/download/G955U1UES2AQL1/201500/
I'm just so glad everything is working now. Thank you so much to all who have responded to the thread to guide me in the right direction! Hope this helps someone else who may be having the same trouble.
I've just purchased a used SM-G930VL (Straight Talk) phone on Swappa. I requested the SM-G930U, but they apparently sent the wrong model.
The reason I wanted to SM-G930U model was so I could insert any SIM card and it would work.
Questions (and I'm new to Android as you can probably tell below):
- Is the SM-G930VL Verizon / Straight Talk model usually unlocked to ONLY use any SIM card from Straight Talk or would I be able to use any US carrier?
- Is there a way to put SM-G930U firmware on a SM-G930VL phone and is there an advantage to this?
- Will the SM-G930U firmware unlock the phone in case it's locked to Straight Talk only?
- Can I brick the phone for good if I attempt to Flash it and I do it wrong? or is it always possible to bring the phone back from the dead?
- Is there a recent tutorial on how to make the phone accept any carrier?
I tried using Odin to Flash the phone from SM-G930VL to SM-G930V, but was following a 2 year old YouTube video, so the files were outdated and I was unsuccessful.
The phone is running Android 8.0.0 and Knox 3.1, API level 25.

Questions (and I'm new to Android as you can probably tell below):
- Is the SM-G930VL Verizon / Straight Talk model usually unlocked to ONLY use any SIM card from Straight Talk or would I be able to use any US carrier?
: the SM-G930VL is programmed to only work with straight talk sim cards. The phone is factory unlocked as far as i know but it does not allow network connectivity with non ST sim cards.
- Is there a way to put SM-G930U firmware on a SM-G930VL phone and is there an advantage to this?
: Yes you can put the SM-G930U firmware. All US Galaxy S7S are the same hardware wise. The Advantage is that it completely removes everything that ST baked into the firmware.
- Will the SM-G930U firmware unlock the phone in case it's locked to Straight Talk only?
: If in case the device is sim locked to ST, flashing the SM-G930U firmware will not sim unlock the device.
- Can I brick the phone for good if I attempt to Flash it and I do it wrong? or is it always possible to bring the phone back from the dead?
: There are always risks when it comes to flashing any device. When it comes to Samsung devices it's hard to really hard brick a device using and official flash tool like Odin. the device cab get soft bricked but most of the times it's because of user error that it happens.
- Is there a recent tutorial on how to make the phone accept any carrier?
: there are many of them here on the forums but i can try my best to give you a quick run down:
1. First download the SM-G930U firmware from here
2. Download Odin from this thread, Credits to OP on that thread
3. Once Files are downloaded, extract the firmware and odin on the same folder for convinience.
4. Once you extract the firmware, you will have 5 files that each start with BL, AP, CP, HOME_CSC, and CSC (you will need BL, AP, CP and CSC only)
5. open Odin and load each file above in there respective slots, you will be able to see where each file needs to go, note that the AP file will take a few minutes to load as this is the biggest file of the 4.
6. at this point am assuming your galaxy s7 is completely off, Press and hold the Home + Volume down + Power keys together until you see a warning screen about flashing custom firmware, press Volume up to get to Download/Odin Mode.
7. connect your S7 to your PC, use usb 2.0 ports preferably. Let Windows install the drivers (you can get samsung drivers from here, make sure you install these first i.e. before connecting your phone to your PC)
8. Once Windows installs the drivers, on Odin, click START and wait for all the files to flash, DO NOT DISCONNECT THE PHONE until Odin says Pass or something similar.
9. The phone will automatically go to recovery mode and display installing update. It will reboot again and start to boot into android. once fully booted.
10. Once booted fully, you will be on Android Oreo for the unbranded Galaxy S7 with nothing from straight talk and also you will be able to use any sim card on the device.
I tried using Odin to Flash the phone from SM-G930VL to SM-G930V, but was following a 2 year old YouTube video, so the files were outdated and I was unsuccessful.

btw i know this because i myself got a straighttalk galaxy s7 when it first came out. i switched to the unbranded firmware as soon as it was made available and have not gone back to the straight talk firmware ever. the phone behaves like an actual unlocked SM-G930U device and gets updates (albeit a little slower than carrier branded S7s) directly from samsung.
Also once you follow, this go to settings and software updates to get the latest available updates available from Samsung.

Apologies for not answering earlier. I really appreciate your offer and thoughts, however I just returned the S7 and purchased a used S8 instead.

Hey thanks for the thread folks!
I am also (an old) beginner! Followed the instructions (Thank you @micallan_17) and was able to successfully flash stock G930U into a T-Mobile S7 which was supposed to have been unlocked when I bought it, but apparently was not! So, with G930U everything works with my Consumer Cellular SIM (AT&T network), but I can not call out or receive calls! Flashed phone back to T-Mobile stock G930T and took it to a T-Mobile store. They were kind and put a demo SIM in it and it worked to call out. So, the hardware seems to be working. Back to G930U, I have wiped cache and data, but still no calls! Can send and receive text, WiFi works and have 4G LTE functional. It also shows the VoLTE option and WiFi calling, but won't do either. Basically, it is a smartphone that is only smart!
Any brilliant fixing suggestions out there?

Hi, Glad the instructions were helpful, regarding the call issue, when you try calling, does it give you an error message? Also when you go to settings>connections>mobile networks, what shows under Network Mode?

Hi, thanks for the reply.
When I call a number, it acts and says it is dialing but it is quiet even with speaker on, and after about a minute it hangs up. No error messages appear. Calling the number from another phone goes to voicemail after a couple of rings, as though the number is busy or off. The Network Mode shows as LTE/3G/2G (auto connect). I also noticed that WiFi Calling that showed up with T-Mobile is missing with this setup, so I misspoke previously.

First an update:
So, after I was convinced that the phone was still locked to T-Mobile, I wrote to the seller and they offered to exchange it. I got the second S7 and it is working fine, still T-Mobile but obviously unlocked! Now I am thinking of flashing it with the G930U ROM, but am not sure if it will affect the unlocking.
My question is just that: I assume the boot-loader is locked; then will going to the Samsung unlocked ROM mess things up? And if it happens that I can not call out with it like the first unit, going back to G930T ROM may not bring it back to the current state!
Has anyone have words of wisdom in this regard?

It should not lock the Device, the U firmware should flash just fine, Flashing the U firmware does not affect the boot loader locked state. make sure the device is permanently sim unlocked not temporary unlocked.

The major benefit (if any) of U (unlocked/carrierless) firmware (from posts in this and other carrier threads) is the avoidage of carrier-specific applications (which are almost universally regarded as *bloatware*). However, because of scripts written by the talented folks elsewhere on XDA, even the most bloated carrier firmware can be skimmed of bloat without the concern that you could be shooting yourself in the foot by not getting a feature that can be firmware-reliant (such as VoLTE or VoWifi). Further, some carriers (Verizon Wilreless most notably) have a stock-only firmware policy (that is, in fact, the biggest ding I have with Big Red).

My S7 (Snapdragon model) is not merely ex-Verizon, but one with a blacklisted IMEI on Big Red; the same would apply to any S7 (the gotcha with a blacklisted IMEI is that you can't take the phone back to the carrier that blacklisted the IMEI in question). The ONLY reason why blacklisted IMEIs happen is going to be contract-breakage (which is commonplace with long contracts - more than carriers want to admit). Still, you CAN take a phone with a blacklisted IMEI to another carrier (in my case, I took it to the the T-Mobile side of Tracfone). Other than that, you can go to any carrier.
Since I have been on the Tracfone side of T-Mobile, I have run T-Mobile Nougat, AT&T Mobility beta Oreo, AT&T Mobility Oreo Final, then T-Mobile Oreo - all without changing carriers, and all on the same S7. (You read that right - for at least two months, I ran firmware technically alien to both carrier AND phone - and it mattered to neither.) What has to be pointed out is that - until the b8 firmware, the ONLY carrier that quibbled about firmware is Verizon - and even that does not apply to their MVNOs, such as Tracfone.) Still, you have to wonder, why does Verizon care - especially since no other carrier did - even with phones under contract - until b8 came along - and that is only with the S7 in update-only mode? (It isn't as if Pie were in the offing for the S7.)
