A little help with flash firmware - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hello guys. I am from Europe and just buy Samsung Galaxy S20 Ultra with Snapdragon. The phone is unlocked, but have carrier brand, Verizon, I want to remove it. Can't change phone language (see that this problem is discussed here, but I did not see a solution) and in Verizon miss Samsung Cloud.
I decided to try changing stock rom with Odin. Now downloading official firmware SM 988U, because I read that must put firmware with "U", and downloading SM-988USQU1CTLB (this is my baseband version and hope that this is correct firmware), write only USA, without any brands, from sammobile, I hope that is without carrier brand. Don't know if I will manage to change language successfully, because the phone is made for USA, but hope that carrier brand will disappear and Samsung Cloud will show. Will do this for first time and don't understand a lot of things. However, my question is for Bootloader.... I try to see if my bootloader is unlocked or locked, but can't do it.... If I put new firmware and bootloader is locked what will happens? Sorry for my stupid question, but I try to learn how things happen What you think, is my idea is good or no?

Something is bricks. I downloaded the original stock firmware from sammobile. USA only, I successfully uploaded it, everything with Odin was good, but after restarting and entering my sim card pin code, the phone want pin code to get app notifications. Please someone help me.... What is this pin code? I can only received phone calls

I manage to put the phone in downloading mod, please someone tell me witch firmware must download and install? The phone is SM-988U

Flashing software to NA Region? & unlock?

Hi guys, I am not new to android, I daily flash my Samsung Nexus via CWM all the time.
However, My dad recently went to india and i believe got his phone unlocked their for Indian sim cards to work.
Now if they flashed a indian rom on the phone as well, How do i flash the native BELL rom? also, How do i unlock this?
I read around one has to download multiloader and find the Bell Flash file, or whatever the stock one is that Bell gives out in Canada.
Can anyone help me with this? I'm new to this area of XDA. Basically I need a Bell stock flash file, and need to network lock his sim card back to Bell again.
Cheers
Ok So from reading around it seems like I should do the following:
-Download Multiloader--- Done
- Download Bell Software from SAMFIRMARE, Im downloading the Firmwares for GT-S8500M - Canada (Bell)? is that right one?
- Follow http://forum.xda-developers.com/showthread.php?t=1759424 guide to flash my firmware,
and then I should have my dads phone back and on the Bell network right in Canada?
Please give more details so that it is easier to understand you and offer solution.
If I guess right, your dad's phone is Samsung WAVE 8500? And that the phone is completely unlocked now?
If the answer is affirmative, then there is no need to lock it back again to Bell Network. An unlocked phone can be used with any SIM card.
And as the phone was originally of BELL network, just go to Sammobile and download the Canadian firmware for S8500 (WAVE).
Flash your phone with the downloaded firmware and start using it. You don't have to LOCK for it to work with BELL.
The above is only if your dad's phone is WAVE and originally of BELL network. If not, please give more details.
Hey thanks spacks. It was originally from Bell. So if it was flashed to some firmware for india, I will just flash it back to the Bell firmware.
Right now its locked to his India cell phone carrier, So i should probably flash the bell rom to put him back on his original network.
If i run into problems I will post back here, as I am leaving for work now
Edit** If the phone is just locked to the indian carrier, How can i UNLOCK it without flashing a new firmware??
Please read this thread : http://forum.xda-developers.com/showthread.php?t=1473089
Best Regards
Ok i tried the first step to flash the boot files BUT now running into a issue, the laptop wont detect the samsung phone anymore, I tried reinstalling and updating drivers and uninstalling them, Can anyone help me? The phone boots up to the "Samsung Wave I8500M" logo screen but freezes...I really need to flash this Bell firmware asap.
Ooooops
This is not going well as expected :S
Go to SamMobile and download the canadian fw available there and flash it
Then try again with the flock to unlock your phone

Need Android Pie firmware details for Unlocked T-Mobile Samsung S9

Hi All,
I have Samsung S9 Unlocked T-mobile from US and currently in India. Currently i have Oreo Version.
As all know, it doesnt have VOLTE option enabled which is needed for my sim network for voice calls to go through.
Somewhere i read Pie update will have VOLTE option and hence i am trying to update to Pie update.
I downloaded G960USQS6CSGB firmware for T-mobile, but before upating firmware using Odin, i got doubt if it will stick to T Mobile after update. This will make my phone not usable in India.
I tried to check online, but couldnt get direct answer and hence posting in new thread.
Can someone help clarify if it will lock the mobile to T-Mobile or will the phone be still in unlocked state?
Also i see two CSC files in the firmware folder. CSC and HOME_CSC. Which one to use?
If I should update with some other firmware for being unlocked and yet to get PIE update, please point to required firmware name or links.
Also will updating to PIE update will have VOLTE option ? Kindly confirm.
Thanks in Advance.

csc will factory reset your phone, home_csc wont
volte wasnt removed from pie, so that shouldnt be an issue
the firmware version you posted has the 6th bootloader revision, im betting here is a 7th available for your phone, but the 6th version should be fine as well
as far as the unlocked state of the phone goes, it shouldnt re-lock, but im paranoid lol. Have you looked into the U1 versions of the phones firmware? Theyre inherently unlocked firmwares and dont have any of that irritating bloatware **** in them

Thanks youdoofus the inputs. Say by chance if it gets locked, is there a way to unlock the phone again from here?
may be then i will try to load U1 versions otherwise. Thanks alot.

if it has no financial obligation to any carrier and the phone locks to that carrier, then the carrier it locked to would be required to release it. I cant imagine how it would lock to t-mob tho
Factory unlocked phones stay unlocked, no matter what firmware you flash.
Carrier locked phones that were properly unlocked by the carrier (they provide the code to SIM unlock the phone) will stay unlocked, again, no matter what firmware you flash to it - as long as it's compatible. Flashing the wrong firmware may just brick the phone. But, at least it's still SIM unlocked.
Phones that had some kind of software hack installed to trick the phone into thinking it's unlocked will lose the unlock status when you flash a firmware that also wipes the phone. Then it will come back as carrier locked again, because the hack is gone.
That last case is the only case I know of that will "re-lock" a phone. I've never heard of a carrier unlocked phone spontaneously re-locking under any circumstance.
Hi,
Thanks for the details. I tried to flash G960U1UES6CSG4_G960U1OYM6CSG4_XAA firmware. But while loading AP file in ODIN, it gave some error. Couldnt understand what is the error as its in chinese.
Then i loaded G960USQS6CSGB_G960UOYN6CSGB_TMB firmware which i downloaded previously. This got loaded in ODIN without any issues. And i am able to flash to phone. On rebooting, saw that phone moved to Pie version.
But i couldnt find VOLTE option (Enhanced calling) option. Does anyone know which version will enable that option?
Or anyother way to enable that please.
Thanks in advance.

if your Odin error messages are in Chinese, youve obtained a modified version. Itll probably work, but youll get that Chinese stuff whenever it needs to tell you anything. I dont know which versions have volte tbh. Sorry man.

Thanks youdoofus for trying to help. For me atleast it didnt get locked when i moved to Pie. I will try other methods.
I will try to root the phone for enabling volte, but the methods that i tried didnt work.

yeah, sort of. The CSC's on these things are weird. Im starting to believe that these new versions of android are just like windows ISOs where they have all the versions compressed into one file and it uses a directory file to tell the firmware which version to install. Im sure a code writing dev can confirm or deny this thought, but at this point its merely a weak theory

Help Flashing Samsung Galaxy S10+ from VZW to Strait-Talk

Hey everyone,
I'm new to flashing phones but have experience flashing other hardware; still, I felt it prudent to ask for some guidance on this being my first attempt:
I have a Straight-Talk phone which is active and working with 4G that I would like to swap the SIM over to use in my Galaxy S10+ from Verizon.
Swapping the SIM without flashing limited the functionality to be contingent on WiFi; 4G would not work correctly.
So I suspect I'll need to flash with unlocked firmware to get it to work properly.
I have downloaded the G975U1_SAU_1.zip which is what I think I'll be needing to pull this off, as well as the latest available download of Odin (3.14.1).
Before I get started, I'd just like to ask some Questions:
Should I leave the intended SIM (Straight-Talk) in the S10+ (Verizon) while I'm flashing, or insert it after the flashing?
Am I using the correct firmware to flash this Verizon phone to work with Strait-Talk? (United States regions)
Also should I back up the intended SIM in some fashion before proceeding with this process (if so what software if any would be advisable for this?)
Is there anything I need to watch out for?
Am I on the right track for what I'm attempting to do?
Thanks in advanced for any help! :highfive:

Hey everyone,
I'm new to flashing phones but have experience flashing other hardware; still, I felt it prudent to ask for some guidance on this being my first attempt:
I have a Straight-Talk phone which is active and working with 4G that I would like to swap the SIM over to use in my Galaxy S10+ from Verizon.

Insert SIM after flashing. You need the current U1 firmware from sam mobile. You also need the patched version of Odin that's floating around the forums here. No need to backup your SIM, but using Odin will reset your phone to brand new. Nothing that I can think of, you just put the correct Odin file in each slot and hit go. Seems like you're onto it, you need 3 things which are patched Odin, latest firmware, and I think phone drivers so your PC recognizes the phone. Should be able to find these on Samsung website or other parts of the web.
Thanks for the support!
After your encouragement, I rechecked my firmware made sure to acquire the USB Drivers from Samsung.
Successfully flashed the phone and its now working as intended!
:victory:
I used the Frija tool mentioned here to make sure I had the right files.
And the Driver install came from here.
Thanks again for your support! :highfive:

No problem man, glad to help. Good you posted links too so others can do the same if they're having issues.
Absolutely!
Anything I can do to help pay it forward.
I should also mention I got my CSC code from the list posted at
Droid Views dot com /how-to-change-csc-in-samsung-galaxy-phones/
(Won't let me post the outside link given that I'm new)
The code was required to use Frija to download the correct firmware.
(The 4GB download averaged at 2.5MB/s)
Here is the list I saw on the aforementioned page; I used XAA
Code:
[LIST]
[*]ACG – Nextech/C Spire
[*]ATT – AT&T
[*]CCT – Comcast
[*]LRA – Bluegrass Cellular
[*]SPR – Sprint (CDMA)
[*]TFN – Tracfone
[*]TMB – T-Mobile
[*]USC – US Cellular
[*]VMU – Virgin Mobile USA
[*]VZW – Verizon
[*]XAA – USA (unbranded/unlocked/default)
[*]XAS – USA (unbranded/unlocked)
[/LIST]
Random questions:
If you start with a Tmobile GM-S975U that is carrier unlocked (got unlock code from tmobile)
Will it work just fine with straight talk? If not Does changing the CSC code work, and to which code?
Is different firmware required? like U1?

The U1 software for the S-10 plus is strait from Samsung and has no carrier bloat. All US S-10 pluses are the same, no matter who the carrier is. That means you can flash any vendors rom as long as you don't go backwards on the bootloader version. The phone gets set up by the simm card installed on the first boot. The good things about the U1 software is there is no vendor bloat and your updates come straight from Samsung. Don't forget, you have to us the customized Odin to flash with.
Deatailed info and Odin link can be found here. https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704
Thanks for the reply. Should straight talk just work? My friend says data isn’t working on tmo firmware. What firmware and Csc code would work with them?
curious, do mobile Hotspot work, or is carrier still able to block it?

Samsung Galaxy S20 Ultra 5G

I have 2 big problems with my Samsung Galaxy S20 Ultra 5G Android 11! Bought it in Spain, have installed Samsung Firmware through Samsung Menu and BOOTLOADER ID is EUX(is from Samsung itself)!!
Bought the phone in Vodafone shop so this is my service provider Software version: SAOMC_SM-G988B_OXM_ATL_RR_0030 ATL/ATL_ATL/EUX/ATL
I bought a Network Unlock code installed a PHE stock rom firmware but didn't change a thing! So I don't know if the Network Unlock code worked or not because it stays registered at ATL=CSC code Vodafone(Spain)
Tried to uninstall pre-installed service provider programs, got some definetely uninstalled but not all of them, reinstalled an other stock firmware PHE again and nothing got changed again!
So now I need help from real wizards to help me with this problem!
I want bootloader ID CHANGED to PHE for example and want all pre-installed programs definetely uninstalled from my device, at the moment they get automaticly installed at the end of installing new firmware!
Doesn't something exist to format but real format as a SDD from a PC? Something like that should be found out that we can wipe everything and start all over again!
Is there not such possibility with unlocking the bootloader and installing new stock firmware again? I tried that but it fails, does someone now there a solution for?
Network Unlock Code to use to Unlock the Network lock code is locked now because it was a bad code they gave me and now it is asking for a MCK. Anyone knows how to get a MCK code?
