Flashing CSC and UserData on Unlocked - AT&T Samsung Galaxy Note 8 Questions & Answers

Hey guys and gals,
I have a question.
Been wanting to flash AT&T for wifi calling.
But since my phone is my daily driver, I needed affirmation that I can flash just the CSC and UserData.
I am currently on CRG9 build.
Would I be able to flash the CRF6 CSS and USERDATA or will I have to revert back to CRF6 on my phone before flashing?
Thanks in advance guys.

[Q] Updating Bootloader and Modem on S4 i9500

Hi,
I am running Aurora Rom v6 on GS4 i9500 based on lollipop 5.0.1. I have been reading a lot about upgrading modem and bootloader. So first of all i would like to know is it really needed to update your bootloader or modem, if yes then how should i do it ? Do i need to just flash the files via odin in PDA mode or some other mode need to be selected ? Also does it require full wiping your cache dalvik cache ?
Here is my current modem number I9500DDUHOA1.
I am not sure how do i find out which bootloader i am running.
Thanks !!
Can anyone please reply !!

Your device's modem/bootloader version is up-to-date. Modem + BL is included in the stock firmware and you already had installed the latest stock firmware for your region (I9500XXUHOAA - INU) before you switched to a custom rom.

Flashing Firmware / Bootloader / Modem

Hi,
I´m a neewbie to Samsung. My phone is a S6 SM-G920F, Baseband G920FXXU1AOCW
I came form an HTC and I´ve seen that flashing things are very different. So here are my questions:
1. I think, my bootloader is unlocked but I didin´t know for sure. So how can I check this?
(My HTV showed me this by using fastboot, didn´t know if there is fastboot with Samsung and how to start it - only know the download-mode and how to enter TWRP recovery)
2. Flashing firmware via Odin (i. e. from sammobile.com) means to loose my root again, right?
3. If I loose root, where do I get custom Firmwares and how do I flash them (if this is possible)?
4. If not, is it enough to flash bootloader and modem through Odin?
All answers are appreciated. Thanks in advanced.
Maybe someone can link me to an step to step instruction...
Fastboot is android doesn't matter who makes the phone.
If you flash a rom from sammobile then you will go to whichever stock you pick.
Other ROMs are available here. The phone is new. There aren't many yet. Cyanogen mod isn't available yet.
Root is available by flashing cfautoroot with Odin. You will need to get the specific one.
You can replace the recovery by flashing twrp team win recovery project with Odin.
You can flash boot loader and modem. Make sure you get the right region. The modem frequencies are different in different places.
You may find flashing a whole ROM even stock will fail. This is because the partitions are not the same size for all s6 stock ROMs. Don't ask me why. You can open the tar find which file stopped the flash delete it from the tar and flash again.

Thanks for answering. My questions had an other intention, I think.
My S6 is already rooted and I have a custom recovery (TWRP) :good:
I would like to know if you have to flash a whole firmware or only bootloader/modem? Because I didn´t seen a post here for a full firmware yet.
I am not familiar with the differences between htc whole firmware and samsung bootloader/modem
Actually I am on Firmware G920FXXU1AOCW. But there are newer ones like XXU1AOE3 or XXU1AOE4.
In the days of my htc you couldn´t flash only bootloader or modem, you had to flash a whole firmware (like radio, drivers, bootloader, modem etc.)
Flashing only modem and bootloader will it update i. e. touchscreen drivers? If not, where do I get this ones? You know, because of root I don´t get OTA´s anymore...
The modem just controls how your phone hardware connects to carrier towers etc.
The boot loader is a tiny thing that tells the processor where and how to load the OS.
The software for pretty much everything is in /system.
Many of these releases are the same software, region specific. The dates are fairly unimportant for the same version number. They generally reference the time when they were uploaded by someone. Not that they have updates and fixes.
Just wanted to know can I change my phone logo MetroPCS to say T-mobile with all the T-mobile add on. I have a Samsung Galaxy s6 by MetroPCS

Help please! Moto G stuck in bootloader, any help is appreciated!

Hey All,
I have a Moto G 2013 (1st gen I believe). A while back, I wanted to install lollipop without it being available so I flashed the Brazil 5.0 ROM. Now, for some reason it won't boot and I got my phone stuck in bootloader. I can go to TWRP and the bootloader mode right now. I'm not sure what version it is, but I think its the XT1032 (non-lte for sure) and I've used it on Bell, Canada
.
I'm trying to follow a guide to restore back to stock but im not sure which model I should be downloading the firmware for. Can anyone help?
I'm using this guide: http://forum.xda-developers.com/showthread.php?t=2542219 and I tried a XT1032 ROM (Brazil) but when following the first command "mfastboot flash partition gpt.bin" didn't work. Should I just ignore this and move forward? I believe somewhere in the thread it said to ignore it but I'm not positive. Note: I dont want service, I want to use it as a glorified mp3 player for my car
Thanks in advance and any help is appreciated!
EDIT: I tried flashing a couple of roms in bootloader mode via adb from the aformentioned tutorial, but I keep getting errors when trying to flash the recovery, boot, partition, etc. Can anyone please help? Thanks.

It is strange that you can flash ROM in recovery but cant flash rec, my suggestion is checking your rec file,substitute with a Twrp rec and flash again. if success, you can try to flash a zip ROM.
Thankyou for the response! I appreciate it. Sorry, I should've been more clear. I was trying to flash official firmwares through bootloader, not roms. I tried flashing two different firmwares (XT1032, as per the barcode setting on my bootloader mode), and I keep getting errors when trying to flash using adb commands. It sends the files correctly but fails at writing them. I'm not sure what the issue is, but it may be because I was on Android 5 (lollipop) and I was trying an older firmware (i.e. older partition table). Currently trying a 5.0 firmware (brazil XT1032!) If anyone has any advice, please let me know! Thanks again!

[Help] Accidentally set radio to USA band(XT1033)

I was fiddling with the testing menu on XT1033(GCC Model) running Official CM14.1 Nightly dated 12th Nov 2016. I changed the Radio to "USA" as it was the only option. Now I have no data and no network to place calls.It doesn't seem to detect the sim itself. I am not able to change the radio band now.I tried clean flashing the rom again but still no luck.
Is there anything I can do? I have a complete nandroid backup from MM roms. Will flashing any of those help? Or should I unlock all bands for this device by following this guide: http://forum.xda-developers.com/showpost.php?p=55475431&postcount=1
Or should I revert back to stock?
have u tried to flash respective radio/kernel from here??

Flash the radio file from this link http://forum.xda-developers.com/showthread.php?t=2649763 this solved the problem for me. I flashed xt1033 5.1 radio twrp flashable zip file. hope it works for u too
Thank you guys but I didn't have to do any of the things you guys mentioned. I simply clean flashed AOSP 7.0 and then I deleted the radio firmware cache with the following commands in fastboot mode:
fastboot erase modemst1
fastboot erase modemst2
When I rebooted my phone,it worked.
