[Completed] [q] sprint s4 to at&t s4 - XDA Assist

OOOKAAAYY.....after many months of flashing and downloading files. I managed to get AT&T firmware, and modem onto my SPRINT SPH-L720T. I believe it happened after I got rid of anything carrier based, and flashed a google based rom, and then flashed AT&T firmware, CSC file, Modem, and Kernel. Heres the catch...when I did this I lost root and went back to stock recovery. It takes a while to boot, but the at&t firmware loads even with all the AT&T bloat apps, However my baseband is still stuck on L720TVPUBNC6 which is the baseband for sprint galaxy s4. Originally I upgraded it when it still had sprint firmware all the way to android 4.4, but after all the flashing to KK Rom, Cynanongenmod, liquidsmooth etc until the present I cannot change the baseband even when I flash with odin or from recovery mode on the sd card. Do I need to reacquire root , and a custom recovery to do this? Ive spent so many days, and hours doing this, and im finally on the edge of converting this phone completely to AT&T from sprint. My wifi also does not work which I believe is related to to mismatched baseband. Can anyone help?

Wtf ... You cannot flash different model roms... It can couse hard brick from bootloader ...
As of right now can't get beta mm yet but got 920f rom on idk if it's cause the phone u get from ntelos "sprint owns" is a really which listed as generic CDMA no carrier bloat but always use 920f and 920p roms

INSTALL BACK TO STOCK THEN use the cf auto root download this use google to search first one that comes up use that link go to model sm-g920p cspire and sprint uses
the same network . Use odin to install i have same phone and have mine rooted in this way. So far tried using the sprint version custom rom it will work but you can make phone calls but not the data side for phone internet. Make sure you go to settings in the phone under find my phone and turn off activation lock

[Q] HELP G920T flashed wrong carrier stock ROM

I recently received a T-Mobile Galaxy S6, and it was rooted and had a custom kernel, which was a complete mess (the person who owned the phone previously clearly did not know what they were doing) so I just wanted to restore it back to full stock.
I am decently experienced with ODIN, rooting, custom firmware etc, but I have just done one of the biggest rookie mistakes I have ever done. I had accidentally downloaded the most recent firmware for my G920T, not realizing that the file was not for T-Mobile. It was the (XAR) carrier (I believe that is C-Spire but i could be wrong) and the latest was PK1.
It flashed perfectly and all seemed fine until I decided to unlock the device. The T-Mobile S6 requires the use of the "Device Unlock" app and since I had flashed the wrong ROM, the phone thinks the Device Unlock app is not compatible. When I put a different GSM SIM card in the phone, it prompts me to use the Device Unlock app.
I do not have a previous NANDROID backup from the original T-Mobile ROM, and now that I am on the lastest Bootloader for XAR, it will not let me downgrade. I have tried flashing pretty much every MM bootloader and TWRP for both T-Mobile and XAR and none will work (except for what is currently on the device of course) I always get the error "Device: 5 Binary: 4" (sometimes the binary is 3, depending on which version of MM rom or BL I try)
To sum it all up, I am on PK1 (latest for XAR) and I need a way to get back to the official T-Mobile ROM (latest is PD1). Is there a magic method to get this figured out or am I pretty much stuck with what I got until T-Mobile releases an update that is PK1 or higher?
Thank you in advance to all of you that take your time to help (and I am sincerely sorry if I am posting in the wrong section)

Help - Note 8 with ATT Software and ATT Branding, but running VZW firmware

I have an 950U running N950USQS2BQL5 firmware but the boot screen and software is ATT branded.
It's stuck on 7.1.1 for obvious reasons. Is there any way to get it to Oreo besides flashing ATT firmware on it?
Thanks for all help!
If I remember right, the files from Samsung look at the installed sim card and install the correct version from that. You "should" be able to Oden the latest firmware and it will correct itself. It will wipe everything on the phone, so make a backup.

Should I flash my Galaxy S7 Verizon to stock firmware in West Africa?

Hello.
I have a Galaxy S7 that I got about 5 weeks ago. I paid to have it in the box but the person got a secondhand one. I am in West Africa but someway somehow I got a Verizon one that is unlocked for any carrier. Anyway I checked and some functions were not working. Private mode is not working, there's no software update option anywhere (I checked developer mode) and some features I've seen on YouTube are not even on the phone. I'm stuck on Android 6 and can't update so I made up my mind to flash a custom ROM but turns out Verizon's bootloader is locked which will make such a task impossible. Some days ago though, I found out that official Verizon ROMs can be flashed without unlocking the bootloader and this raised some questions which I want to ask here.
Here's the info at the about phone page
MODEL NUMBER - SM-G930V (there's Verizon on the back of the phone so I think this is true)
ANDROID VERSION - 6.0.1
BASEBAND VERSION - G930VVRU4API3
BUILD NUMBER - MMB29M.G930VVRU4API3
1. Can I really flash a stock Verizon ROM for the Galaxy S7 without bricking my phone and with a locked bootloader?
2. If I were to flash a stock Verizon ROM will the phone be locked to Verizon again? I'm asking this because this is the only phone I have and I'm supposed to use this for 2 years!
3. Should I flash the same baseband version or will another Verizon one work?
4. If all the above questions are true, where can I get official Verizon stock ROM for my device?
If you have any questions for me please let me know.
Thanks

Yes, you can flash Verizon stock firmware without issues, as long as you are not trying to flash an older Verizon stock firmware than the version you already have. In other words, you can upgrade, but you can't downgrade.
As for flashing a west African firmware, Nn, Verizon devices have a locked bootloader, the locked bootloader will not allow you flash anything except Verizon stock firmware. Attempting to flash anything from another region or from a different device will only result in a soft-bricked or hard-bricked device. You can only flash the Verizon stock firmware for your specific model number.

Hi! Thanks for replying! So where can I get a Verizon stock firmware that is an upgrade of mine and what region should I download from? Also which version of ODIN should I use?
