Pls help me to get correct Firmware version installed on my Mobile.

I have Samsung S3 GT-I9300CDMA /GSM mobile global unlocked mobile.I am using CDMA network in India. I want to install CM11 or 12 on mine mobile but I think it’s not possible as bootloader is locked. The snap shot of the android firmware version is attached .I have rooted it with towel root app but unable to unlock bootloader as its android version4.4.2.I tried to install TWRP recovery but its failed.
It seems that Verizon SGH-I535 4.4.2 stock ROM Is installed on Samsung S3 GT-I9300 mobile.
I want to install safe strap on mobile,before that I want to download 4.4.2 stock ROM which is installed on my mobile.Pls suggest
1) Which firmware I have to flash in case its get bricked? Verizon I535- 4.4.2 stock ROM or Samsung S3 GT-i9300,Base band version I9300XXUGNA8,Build number KOT49H.I9300XXUGND5 ?I am unable to find out the firmware installed on my mobile on google.
2) Can anyone provide me the link from which I can download this firmware.
3) Can I flash any other ROM using ODIN for Sprint /Cricket on which bootloader is locked ?& use CDMA network
Pls help.

Before flashing anything I would recommend you verify the bootloader and modem on your phone with either the Phone Info *Samsung* app by vndnguyen from the Playstore or with these terminal emulator commands:
Code:
getprop ro.bootloader
getprop | grep version.baseband
I checked the sammobile site to see what I could find about the baseband and build versions you inquired about. I didn't find the NA8 bootloader for the i535, i747/i747M, or i9300. My concern that you use the correct firmware/stock rom arises from the fact that the i535 and i747/i747M use different processors than does the i9300. If you flash the wrong one I would expect your device to be bricked.

Dawgdoc thanks for reply. The bootloader, base band version and hardware details are attached. It's GSM mobile programmed to use CDMA network in India.

This is a bit odd to me, unlike what I have seen reported before. Based on your screen shots; the bootloader, modem, and csc are from the Verizon i535 KitKat release. The device was in the US with a Qualcomm dual core processor and 2 Gb ram. For the i535 this bootloader is indeed locked, fortunately you can install SafeStrap when on this NE1, sadly you can not install any AOSP/CM custom roms. From what I have read, flashing this on the i9300 should brick it. The i9300 has a quad-core exynos processor and 1 Gb ram.
The PDA version confuses me. It is supposed to be from a 4.3 stock ROM for the i9300 that was only released in the Nordic countries.
The Hardware screenshot indicates you have an i535. The CSC screenshot indicates the VZW i535 and something about CHN (China ?).
The General screenshot is back to divided between the i535 and the i9300.
I am not confident enough to tell you what the status of your phone is and what would be safe to flash.
@audit13 @ShapesBlue @DocHoliday77 do any of you have experience with a similar situation?

@dawgdoc sorry man I sure don't. I'm not even sure what to do on this one

I am also stumped. Was the phone sold as brand new? I have an LG G2 and have read stories about people getting frankenphones when buying refurbished.

As per seller its refurbished phone & unlocked to use GSM / CDMA network.But if i check the IMEI number on site http://www.imei.info/ its displays message invalid IMEI.Is this mobile is cloned?
But if i check my mobile for Refurbishment check with Phone Info *Samsung* app by vndnguyen from the Playstore,in displays mesage "Your phone is ORIGINAL"if serial number checking was skipped.
I am confused whether this Mobile is Genuine or not?

The only thing I have left to suggest is posting in the i9300 forum to see if anybody there is familiar with such a situation. I usually see the guys I tagged in the i535 and i747 forums.

I have posted this in i9300 forum.

I have installed safe strap version 4 and backup my Rom.can I flash superliterom v_5.0_ i535_VRUDNE1_deodexed. Zip using safe strap? In case after flashing if my mobile get in to boot loop, can I restore back my stock ROM?
Pls suggest as I don't have Stock ROM file to flash using Odin.

Team I am able to install superliterom v_5.0_i535 VRUDNE1_deodexed.zip using safe strap version 4 on my phone.

Sorry I wasn't able to reply sooner.
I am glad to see you have it working.

Thanks dawgdoc and others for providing information that they have, about the firmware installed on my mobile.

Invalid SIM card

I have an S5 Sprint (G900P).
Bought and using it from outside USA.
And it was unlocked for international use.
I could use 2G and 3G on it.
But was unable to find and connect to 4G.
So in order to enable 4G, other than doing various things, I ended up reseting 'provisioning parameters to factory defaults' using ##72786#
Since then I am unable to use SIM.
It says, "Invalid SIM card"
Seems like I have lost unlock!
Now what options am I left with to make SIM work again on it?
Build number: MOAR v7.0 OA6
Software version: G900PVPU3BOK4
Android version: 5.0
Baseband version: G900PVPU3BOK4

you re-simlocked it. that factory reprovisioning thing you did undid the unlock process. Your options are to get the simunlock code from sprint and if the ROM asks you for the code when you put card in, unlock it that way. But if the phone doesnt ask you for an unlock code, youre likely gonna need the services of a 3rd party unlock company. there are a couple of members on here that have done some unlocks for free or with a donation to them. @stifilz and @asadnow2k. Otherwise, i personally recommend idoneapps.com

Need help with SM-G920A

Hi,
I am using samsung Galaxy S6 ATT version with the following software version:
Android Version 6.0.1
Android Security Patch September 1,2016
Baseband Version G920AUCS5DPI1
Build number MMB29K.G920AUCS5DPI1
The phone is sim unlocked but I need help with rooting / unlocking the bootloader. On checking this forum I did not see that there is any way to do this on my version. So I was just wondering if there is anything else (such as installing any other ROM) that I can do with this phone.
Since the contract on my phone has expired I tried using this phone with another carrier and it does not seem to be working (tried with metroPCS) the phone does not show any other network operators except ATT/T-mobile and Verizon and on trying to connect to T-mobile it fails to connect (metro PCS uses T-mobile line)
After spending few hours with an account rep from metro he felt the phone may not be compatible. So at this point I am just trying to figure out if there is anything I can do with this device.
Sorry for the long winded post but I just hate how these carriers tell you that after the contract you own the device but their own software updates mess up any chance of using your own device as you want.
Appreciate any insight or links to help me figure out if anything can be down to get rid of the ATT rom.
Thanks,
Matt

What can I do with a SM-S515DL Tracfone device?

Hello everyone, I've been looking for some information about this Galaxy a51 (which I think it's a US version and I'm outside US) with the following features:
Model number: SM-S515DL
Android Version: 11
One UI version: 3.1
Baseband version: S515DLUDU8CUK1
Kernel version: 4.14.113-22754548
Service provider software version: SAOMC_SM-S515DL_TFN_TFV_RR_0015 TFV/TFV/TFN
Software update info version: S515DLUDU8CUK1 / S515DLTFN8CUK1 / S515DLUDU8CUK1
Security patch level: October 1, 2021
I got it from Amazon and it says it's a CDMA device, of course it is network locked and it's showing the invalid SIM card message. So I got a couple of questions hoping you can share your comments:
1. Is it possible to do a stock firmware flash and get rid of carrier content and locked SIM?
2. Can I use galaxy firmware.com files to do so? I see there is a S515DLUDU8CUK1 version with different region, if so which region to pick?
3. or maybe is it possible to do it by installing a custom ROM?
4. Could the z3x or octoplus unlock network? (I can't get the unlocking PIN or region screen)
There are still a lot of things to learn, unfortunately I saw there is not much info for this model on forum sections. I found mostly information for A515F and other variants of a51, could I just use them? is there any risk? Beyond the unlocking network I'd really like to try a custom rom and get rid of all the stuff it comes with.
Greetings!

Yeah, eveything should be possible, but you must change you language manually after setup, when you flash a different Firmware from another country or another region. If you flash a new Firmware you also should be able to unlock your bootloader and then you habe the Go for flashing every Rom you want. With a different Rom or Firmware you should be able to get rid of Carrier content etc.

Okay so far I've been using it as an offline device and it is just fine. I am waiting for SamKey to release the network unlock since it only supports binary 3 and below. I dunno which other software supports binary 8. My bootloader is locked it does not show up at developer options.
Anyway I am just playing games on it, watching videos and surfing the net with wifi. Just like they say if it's not broken don't fix it. I will just wait until this device gets more support and then I'd probably try roms and other stuff.

Not sure if it will get much support being from 2019. I'm not an expert with Androids but bought same models from Tracfone and with 60 days after activation they were eligible for unlock. They took IMEIs and sent email with two codes in it (different based on IMEI because for two of my devices they were different). after punching number it brought up the device unlock menu and after the two codes were entered got messages that they're unlocked. worked with different sim without an issue afterwards. Its currently up to Android 12 UI 4.1 as far as official updates.

will this work on a tracfone variant

Need Help with At&t Note 20 Ultra

I just purchased a used Note 20 Ultra that was originally for At&t and unlocked, I am using it with my T-Mobile sim and all works fine. I am little concerned as the UI is 3.1 and Android Version is 11 and it says software is up to date, is this correct?
Before I purchased it I also requested Unlock code from At&t and they sent the Unlock code which is weird since it is already Unlocked .....Maybe I am just being paranoid.
The imei on the phone matches the imei on the back of phone and shows all clear on swappa imei.
So the question is how can I tell is any software/fw was altered on this device to Unlock it early?
*#1234# shows the following versions:
AP: N986USQS2DUH3
CP: N986USQS2DUH3
CSC: N986UOYN2DUH3
Model: SM-N986U
I have installed Phone Info+ (SAM) in case anymore info is required to help with this
Thank you in advance for any help.

I think that I'm in the same boat. I received a insurance replacement phone that was unlocked, but I think that Geek Squad had to get an unlock code to get it to work on Tmobile. My phone has never been updated. It's still on the software that it shipped with. My old phone had the black screen of death, and I'm trying to flash a more recent version of Android with Odin. What's your baseband version?

My Baseband version is N986USQS2DUH3
