[Q] Reverse Flashed Galaxy S3 from Cricket back to Verizon

I made the mistake of not meeting at the Verizon store and bought a Galaxy S3 off Craigslist. It has a clean esn but it won't read the 4G sim card. I found out it was flashed to Cricket so I used Odin to flash it back to the original rom that came with the version of the phone which changed it to Baseband version: I535VRLEC but this still won't work it still has the same problem reading the Verizon 4G Sim.
I guess my question is... if there is a different rom I should flash it too? Or is it that once it has been flashed from Verizon to Cricket it can't flashed back to be used on Verizon again?
I would just get a new sim card from Verizon, that may resolve your issues. A few questions:
1) Does it still make calls and texts? The main issue is it doesn't connect to LTE? Maybe I'm not understanding your issue entirely.
2) Does the phone have your phone number and matching IMEI (labeled on the retail box) listed in Settings/About Phone?
You could Odin the stock image VRALF2, VRALEC was a pre-release image. Do not accept the OTA then dial *2767*3855# to reprovision the sim card. Maybe see if this resolves your issues.

Well when I brought the phone in the first time to get it activated I was switching from a Droid X so they gave me a new 4G Sim card. But yeah it won't make calls or texts and it won't connect to there 4G data network or pick up the sim.
So are you saying changing it from VRALEC to VRALF2 might fix it?

Oh yeah and I don't have the box it came in but my phone number did show up in the Settings/About Phone
And at the store they told me it was picking up the Verizon network it just wasn't connecting I guess? so it wouldn't get on the internet or make calls or texts

What I was saying is that normally people Odin to VRALF2 or VRALG1 then reprovision their sim card. That code will work on VRALEC but I was just trying to put you on a common starting point since we here don't really use the VRALEC stock tar in Odin. Primarily what you'll find in the stickies are VRALF2 and newer images. VRALF2 was the "store bought" earliest software version of the Verizon GSIII from the summer. Its worth a try but consider the following first.
Since you said it doesn't call/text then I think you lost your IMEI. Could you check for me under Settings/About Phone? It should be 15 random numerical digits if I'm not mistaken. If its not 15 digits, it will be 0 or several 0's. Don't post the exact number if it is 15 digits, but tell me what you see.

No I didn't lose the IMEI it's still there, all 15 digits.
So is it possible to flash a Galaxy S3 from Verizon to Cricket. Then back to Verizon? Is it just a matter of changing to the right software?

Honestly I know nothing about flashing to another carrier. It's not something that I have a reason to research so I'm not knowledgeable in that area. My suggestion still is to run that reprovision code since you've already Odin flashed to VRALEC.
EDIT: To clarify, my suggestion is Odin VRALF2 then run the dialer code.
Just as a precaution, you should write down your IMEI, ERI, and maybe even your MIN and PRL version and store them somewhere on your computer. Since you don't actually have the retail box, this should be kept safe if we can't get this current situation straightened out. My reasoning is if you do somehow lose these before you're 100% fixed, having them written down may help you if you need to use one of the IMEI or ERI tools in the dev section.

Ahh, great! When you do just make sure to root, unlock your bootloader, make a nandroid backup in CWM or TWRP recovery, then use the "Comprehensive IMEI /EFS Backup" thread to properly backup your IMEI.
I encourage you to flash roms until you find something you like. I'll suggest that you stay with touchwiz roms then see whether sticking with Samsung's software in its various forms is good enough for you. If not, there's plenty of AOSP to go around!
So you just followed step 5 on the link above and it worked? (flashing with 4.0.4 ROM)
I'm going through a similar issue and been having a hell of a time getting mine to work. Mine was flashed to work on nTelos which is a CDMA provider in my area. I have flashed to just about everything possible (except 4.0.4) and haven't had any luck.
I went to the Verizon store and they tried to activate the phone but they couldn't but game me a sim to use and told me to call back if and when I could get it flashed back.
I tried at one point to take a working sim from another phone but it will not activate..... will not make calls, will not get data etc etc. when I dial 611 it still goes to ntelos.
Someone suggested putting Phone info on and setting the Phone to RUIM but I could not find that setting in Phone Info (even on the correct phone info, after time I found out the original phone info was pulled from the play store and I had to manually download it.
Anyway with the SIM I have and following section 5 as suggested mine does not give the option to accept or deny the OTA so I can try to enter the re-provision code. Should I get hold of the known working SIM to attempt this?
THANK YOU SO MUCH!!
The key to this however is to have a working SIM (the only one in our workplace was from an iPhone 5), I fashioned a nano SIM to mini SIM adapter and got the info on to the phone then my phone could finally be activated however the nano SIM I used got tied to my phone and couldn't be put back to the iPhone 5 it came from lmao... so I had to run to the Verizon store to get my co-workers phone re-activated.
But going down to the 4.0.4 and VRLEC modem then inserting the active sim, reprovision once it activates (it didnt give me the option to not allow it to do anything), then insert the mini sim, call Verizon they got it activated, I just now updated back to 4.1.1 (need to get 4.1.2) and everything is working wonderfully!!
All of this info is extremely refreshing to hear since I have the same problem with one exception. My s3 has a bad charger port. Sent it in for warranty repair and Samsung said it was moisture damaged and corroded and is not covered under warranty (lies). But that is beside the point and another subject.
My question is, can all of this stuff be done through the sd card and not through the USB? I know it is a long shot but any help would be greatly appreciated.
Thanks!
I know this thread is a little old but I just wanted to say thanks, the exact same thing happened to me (phone was previously flashed to cricket but i was unaware until AFTER purchasing and trying to activate)
ODIN Flashing the OMBINATION_I535VRALG1_I535VZWALG1_743127_REV09_user_low_ship.tar.zip package then reprovisioning with the *2767*3855# worked like a charm, I was sweating for a while as the deal was from craigslist
So far as i can tell to do this you NEED to use the VRAL as I tried a few other (newer) stock files and this was the only one that worked
THANKS AGAIN!

I cannot find an older version of the LG Mobile support tool to flash a stock anything becuase the tool auto updates to current version. I cannot find any CAB files for the D850 either for the CMD version of flashing. all i can find is KDZ files which I have leared how to use through the day. But still having no luck.

Yes, and after many trial and error, i got it to work. I got the phone fully working and i was beyond happy. so I bought an unlock code ($10) for it, and i went to put it in, i had to put it in a few times for it to take, but now it just keeps cycling between no service and and searching, but end result, i now have a fully working LG G3 with no signal with the SIM card i use, i popped the sim card back in my old phone, works fine, i called metro pcs n they said they can accept that phone no problem. so now im really lost, i re-downloaded the TOT and DLL and reflashed the phone twice just to be sure, doing a full wipe n flash. then doing factory reset to be sure I was making it a clean boot, but it still will not cooperate with my sim card. but it works fine when i pop a de-activated AT&T sim in it, But now any non-AT&T sim i put in, the phone doesnt really accept it. it doesnt prompt for the code anymore, but now it doesnt grab a signal.

[SM-G920R7] S6 Thread

My goal would be to install Cyanogenmod on my SM-G920R7, but haven't been able to find too much help. Any of the rooting methods that seem to work on rest of the S6 variants, doesn't seem to work on this one. There is no TWRP available that I know of.
I would really appreciate any possible help. Thanks in advance.
i have the same problem
I think that this version of the s6 (the cspire version) isn't widely available enough and no one has bothered to make a root for it - ive been searching for a long time and still haven't found anything
I'd like to at least be able to root this thing.. On 5.1.1 now.
I have a rooted cellphone of this version (I purchased it rooted), is there any workaround to unlock GSM/LTE bands on this device?
----
Edit... Okay, so I went back to fresh stock with SmartSwitch, then flashed twrp-3.0.0-0-zerofltespr and Unikernel-v9b-BOH1-920P-100815 via odin 3.10.7, and rooted again... any method to enable gsm on this device yet?

Yes, it was SM-G920R7... first, I flashed twrp-3.0.0-0-zerofltespr , then Unikernel-v9b-BOH1-920P-100815 , both via ODIN (you can google both files), note these files are NOT for r7 version (they're for sprint version *g920p*) but they'll root the phone.
I ended up getting rid of the phone as there's afaik no way to enable gsm on it

That's not true. I finally rooted that model and got TWRP installed, and followed the steps to get the Sprint Galaxy S4 domestic SIM unlocked. I finally got data and texting working last night, but I can't get calls to work for some reason on an AT&T SIM card. It even shows up at AT&T as my provider. AFIK it is now SIM unlocked, the only thing not working is calls like I said. I'm sooooo close to getting this working. I need people with this phone that are doing the same thing i'm doing! I only paid $50 for it! lol

Wonder if anyone has got calls working using GSM sim card? I have the cspire G920R7 rooted with LTE data working using AT&T sim.
Won't receive calls (straight to vmail) and when placing calls dialer says CALL ENDED immediatly after dialing.

I'm working on this too. So far I've got the same situation as you, Data works but no calls/text.
in a few weeks the person who wants me to unlock this phone for them is switching carriers and plans on buying a new phone to use until I can unlock the S6, so I'll have more time to mess with it then.
There's a few things I want to try, but I can't post links here (XDA rules).
One involves Rooting and using a service code to unlock the bands (google "TeamUSCellular GSM unlock S6")
The other also requires rooting and involves using "galaxy tools" to unlock the bands (not sure if this app works with marshmallow, though) (google "theandroidsoul how to sim unlock sprint galaxy S6")
My hopes are not high for getting this phone to work fully. I've also been trying to get custom ROMs to work, but I can't get the cell radio to work at all on custom ROMs. Even with the stock SM-G920R7 Kernel straight from the latest update .tar

Thanks for the suggestion, yeah I have tried galaxy tools (GT) to change the phone mode to LTE/GSM auto and tried different CSC values, and accessed the hidden menus through there. The sim unlock in GT asks for a code which I dont know, but the phone doesn't seem to be locked anyway since it doesn't care when I try different sim cards. Weird thing is the GT app doesn't work very well (most hidden menus not working) on the current rom i'm using but worked better on the stock cspire rom. Note, I tried using MSL 000000 in ##3282# data menu and it works but most the settings in there don't seem to be applicable to GSM networks.
Currently I'VE been messing with the build.prop file, also tried the CDMA to GSM flashable zip which edits the build.prop but nothing has gotten better. One time after editing the build.prop the phone would only turn on with a blank screen and vibrate every few seconds, that was SCARY. Also was planning on flashing other radio/modem but having trouble finding many of those files and pulling them from roms seems difficult to get the correct file to flash on odin.

I'm not sure you'll even be able to flash other models' modem..? I can't say I've ever tried.
Anyway, getting your hands on the firmware is easy. Just use SamFirm (http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647)
To use it, just input the model number (SM-G920R7/R4/P/V/T/A) and the region code, then select "auto".
Region codes and model numbers:
C-Spire: ACG (SM-G920R7)
US-Cellular: USC (SM-G920R4)
Sprint: SPR (SM-G920P)
Verizon: VZW (Locked out from download, app can't download) (SM-G920V)
T-mobile: TMB (SM-G920T)
ATT: ATT (Locked out from download, app can't download) (SM-G920A)
This app downloads firmwares directly from Samsung servers, so the download is really fast and guaranteed to be perfect/stock.
**the SM-G920R7 is closest related to the SM-G920R4 (US Cellular) & SM-G920P (Sprint). The US Cellular one recently supports GSM Bands natively without any rooting/messing with hidden settings, so that's where i'd start. You may not even need the baseband/modem, just flash the rom? I'm not sure. Good luck dude It'd be awesome if you get it working
*** Also, make sure you have a backup of your EFS before messing with the modem. Apparently if you flash an incompatible modem you can erase/corrupt the EFS partition and lose your IMEI. Hell, make a FULL backup with TWRP, and make sure that backup is copied over to your computer before doing any flashing. You can't be too careful with this.
Haven't had any luck flashing stock firmware or modems from other models using Odin, errors with a security message or something, tried G920A and G920R4. Probably for the best I suppose. Flashing custom roms has not been a problem, even if the don't work properly. Wonder if there is a test mode or way to use logcat to see why calls don't proceed like normal. Never worked on going CDMA to GSM before, I always did CDMA to CDMA in the past.

Trying to flash T-Mobile Stock Rom 5.1.1 modem to Sprint Galaxy Note Edge

I have tried flashing many different modem.bin but all of them fail inside of odin, now I am wondering if it is even possible to unlock my phone for use with a t-mobile sim card. The device can easily take and recieve calls under sprint rom but i am unable to connect to any tmobile towers and thus cannot get any data. Any suggestions?

Question Samsung S21 VZN need unlocked or converted to ATT. Tried odin.. Maybe I am an idiot.

Hello.
Got a free phone from a buddy S21 5G. I am wanting to swap it for the S10* 1tb I gave my wife to use it was a bit expensive. So I'd rather ti go back in the box.
Popped the sim in it, it works makes calls sometimes, sometimes not. Texts seem to always work, I am currently on ATT I would prefer to have that firmware as I live in the stick with ho cell service. ATT has wifi calling which is pretty much a necessity here.
So what exactly do I need to do to get this off the VZN fir
Hello. Could you all provide me the links for what I need? Found a link that had a patched Odin plus the firmware. I installed in booted how I was suppose to. Tried to install in and it errored out.

Hello, did you manage to flash the phone?, I'm stuck with a similar case, mine is a factory unlocked unit from Verizon, it turns out that even if it is factory unlocked, is locked after a few minutes by verizon, I have tried everything to get rid of the VZW firmware but it seems that Verizon locks the bootloader so I can't flash it (it passes om odin and everything but the firmware doesn't change)
I even paid SamKEY credits to change the CSC but it didn't change either.
