[Samsung Galaxy S21 Ultra] ALPHAZULU307:
Hi all, tried flashing last night. I'm not sure if it actually worked, all data was wiped. But when I started setting up my phone I got a message pop up saying a factory reset was attempted and to enter my phones pin code witch I did and set the phone up. My issue is I still can't access the one ui 4 or others. Do I need to disable smart lock first? How can I verify if it was completed if the smart lock doesn't matter, and if not what is something else I can do to complete the flash, thank you very much!
[Samsung Galaxy S21 Ultra] ALPHAZULU307:
for anyone with this issue,

remove sim

factory reset

set up phone without inputting any info other than wifi if prompted skip the rest

download firmware from a similar counties code

flash phone with that firmware

download your countries firmware and flash again

set up as normal

put sim card back in

completed!

I have been reading various posts about flashing a S21 Ultra to an unlocked firmware mainly to get the texting and calling with my tablet again. I've read a few posts which has me guessing on whether the process will work. I have a Verizon locked cell phone will flashing an unlocked image on the phone give me that feature or do I have to get Verizon to unlock the sim card and flash the unlocked image for me to get the calling and texting feature again?

Was thinking about flashing U1 on my AT&T S21u. Is anyone still having issues with features not working?
[Samsung Galaxy S21 Ultra] maddoggin:
I'm guessing unlocked (g998u1) s21 ultra has not received Android 12 yet? Only tmb and Verizon? That's strange! Usually unlocked gets it first.
[Samsung Galaxy S21 Ultra] Parzival__:
I just wanna say holy heck thank you my dude. My first ODIN flash was a success. Ive done alot of things, IMEI unblacklisting, FRP removal but I was always afraid of this in case I bricked my phone or a customers. So I mean it when I say thank you. Noe that Ive done it its not so scary after all.
[Samsung Galaxy S21 Ultra] Parzival__:
That is correct. The reason being is when patches like this are released phone carriers have to certify the update for their network and be able to broadcast it via OTA. So since those are the only 2 that have certified said update those are the only ones to have it.

Hello,

My current at&t S21 Ultra SM-G998U does not have e-SIM but I had someone check the phone and he said that, the phone is supports e-SIM, it seems AT&T disabled it. So, I want to know, if I flash this official SM-G998U1 firmware, will I get e-SIM?
[Samsung Galaxy S21 Ultra] afaque_hassan:
i'm using a verizon model , in saudi arabia . Can you please tell me which rom do i need to flash.

Another thing i've noted is i cannot assign one sim for calls and another sim for data. Has Samsung removed this feature from their flagship devices? Because it is available in A series phones. I have option to only select primary sim which will be used for both calls and data.
[Samsung Galaxy S21 Ultra] ALPHAZULU307:
I'm definitely not a developer so I can't tell you witch to use I only shared my experience to help anyone having similar problems, I suggest you do a little more research, it took me 5 days to get it all set and figured out any thing more than that you'll have to find
[Samsung Galaxy S21 Ultra] ALPHAZULU307:
Stop being petty do your own research: that's not what people are here for,
[Samsung Galaxy S21 Ultra] afaque_hassan:
That's what I've planned. Downloaded a bunch of U1 roms. Will give it a try in the weekend and see which suits better.

Also, can you please verify if you have the option to assign one sim for calls and another for data. Because since the start of support of dual sim in s21 ultra , i got only an option to select primary sim which will be used for both data and calls.

Thanks for taking time to reply...

Why is it when I flash G998U1-XAA to my Tmobile S21 Ultra without the sim card my CSC still comes up as tmb/tmb/tmb, this is with no sim card in the phone.
[Samsung Galaxy S21 Ultra] skeven:
Keep getting time-out fails

I have a newly purchased Verizon G998U on 4AUIN trying to go to U1 on 4AUJ7.

Checked the md5 of the package I downloaded and that checks out to the md5 on samfw.

I'm using Odin 3.14.4, would get a SHA256 error the first time then a time out fail the second time. Tried using the patched 3.13.1 and just get the time out fail. Using CSC and not HOME_CSC. Would prefer to stay on Android 11 for now (so no 4BUK7).

Any advice?

Just flashing CSC.
[Samsung Galaxy S21 Ultra] Cashreedhar:
I flashed the u1 firmware on US Cellular model using the CSC (not home CSC) and the flash was successful. Now I am using the phone with Verizon and I see something unusual. The service provider software version under software settings is USC/USC/USC (which I expected to see USC/USC/VZW) and under SIM settings my Verizon SIM shows as US Cellular. Also, in the lockscreen it shows US Cellular instead of Verizon. What went wrong and how can I fix it? Call and data work fine except 5G.
[Samsung Galaxy S21 Ultra] mapl.ph:
I live in the Philippines, I feel that flashing my unit to U1 locked me to US bands. I'm currently not receiving 5G signals on the phone. What I have is the 12/128 Snapdragon variant and my network here supports n78 (3500) 5G bands. WIll I get 5g signal if I go to W firmware?
[Samsung Galaxy S21 Ultra] Limon_Lime:
Ok guys I am having a very strange issue. I have tried three different SIM cards all on the Verizon network and none of them work. No data, calls or texts.

The one I want to get working is my Visible SIM. But I've also tried inserting a Verizon sim, and a tracfone sim on the VZW network.

My S21 Ultra CSC is ATT/ATT,ATT/VZW. So I believe that means it originally was a Verizon phone. So I have no idea why it won't work.

I've tried flashing VZW G998U1 firmware and still nothing. When the phone boots it actually shows the AT&T logo.

I've also tried flashing to XAC and back to no avail.

I'm at my wits end here. What network did this phone originally start on and why can't I get it to work on the Verizon network? T-Mobile works fine.

Carrier/SIM Unlock - Galaxy S21 Ultra 5G SM-G998U & U1 (QualComm SnapDragon) USA/CANADA! - NO ROOT- FREE​

Here's a free How-To on how i successfully Carrier/Sim unlocked my Samsung Galaxy S21 Ultra 5G running the NEWEST Android update on bootloader 5 (USQU5BULJ)released in January of 2022 that was carrier locked to Verizon and now fully Unlocked...

xdaforums.com

Downloaded Frija , Flashed AIO CSC for U1 , (Somehow XAA always gives me error ) , wiped cache , factory reset still when insert sim shows me error.

Basic question:

1) Does this error means it is network locked ? When i go to Download mode it still shows Carrier VZW ? Where is it come from bootloader ?

2) If i root the phone (i dont care warranty)will it get rid of this ?any pointer will be big help

Hey, I own a galaxy s21 5G which runs SM-G991N with KOO csc and it comes with a lot of korean carrier bloatwares and It works fine other than for the bloatwares but I need a global firmware since i dont live in south korea and so that i can also use spay the firmware I want is SM-G991B with INU csc. Will i be able to do that without tripping knox efuse. ?
[Samsung Galaxy S21 Ultra] Oki:
Well, I have an SM-G998W with CSC XAC (Factory Unlocked Canadian S21 Ultra).

I have flashed the latest U1 firmware for Unlocked S21 Ultra, CSC XAA with ODIN, at this time the latest firmware file is G998U1UEU9EWI2. No problem there, I have switched multiple times between 998W and 998U1.

After rebooting and letting the system apply the Verizon CSC automatically I rebooted into recovery and tried to sideload the update.zip file (998U1 Beta 1) by using ADB.

Well, I am getting this error in recovery:

this device has unexpected build date.; ;the build date of this devices "Tue Sep 12 19:39:29 KST 2023".

Obviously the update was not applied.

If you want to know the details of the process, it is very well explained in the video in the OP of this thread. But it doesn't work for me.

What could be wrong?

SOLUTION: Well, I have found that after flashing the firmware G998U1UEU9EWI2 I had to boot into the system and update the software to G998U1UES9EWI3. From that 998U1 FW I was able to apply the update.zip using ADB from the recovery menu.

I'm sorry if this has been answered elsewhere, but if I were to flash stock OneUI would I be able to flash back to my T-Mobile ROM at any point? Say, if I wanted to send in my phone for repair or warranty. If not, I may wait until my phone is paid off.

The same thing happened to me.

The sitution for me was that I tried to switch from the stock ROM (which uses encryption for "data") to an older ROM which did not use encryption. So first I had to swipe data to get rid of the encryption.

It is hard to tell from your report.

Did you brick your phone?

I have built a new StockRom based on v1.2 (not TELCEL) for ZTE Blade v10 MT6771.

It works great but knowledge of using SP_Flash_Tool is necessary. Link can be found in PDF-File.

Additionally I added the links of Android 10 v2.1 and v2.2. All Files are downloadable.
[Blade General] akremlTE:
Merci
[Blade General] kilowatito17:
Installation of “Android 12” is also possible.

1. Install Stockrom 1.2 (see above) without formating

2. Boot “Recovery”

3. Wipe Cache and Data

4. Boot "Bootloader" and install "TWRP"

Use “adb” or “TWRP” flashing custom rom.

Roms available here: https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

I was testing - DescendantOS, ArrowOS, Corvus, crDroid, AOSP, CherishOS, SuperiorOS.

I examined in particular "Rooting" and the functions of "TWRP" successfully.

But stay carefully. I don’t know if all functions are working.
[Blade General] windw:
Is 'Android 12' working fine on the phone? Thanks!
[Blade General] kilowatito17:
In particular, I tested only "Root" (Magisk) and "TWRP" functions. Other apps also worked very well. For example, "Google Speech" had no problems. However, I did not test the phone function, since I did not use the main phone for my tests.

Suggestion: To be on the safe side, make a complete(!) backup with TWRP, using a USB stick (16GB or more) as storage. But first format the stick with ExFat, not FAT32 or NTFS, because the file 'system image = system_image.emmc.win' has about 5GB. Well, it takes some time ... about 20-30 minutes.

So far positive: SuperiorOS, KomodoOS, crDroid, CherishOS, xdroid, EvolutionX, dotOS, Descendant, Corvus, Awaken, AncientOS, ArrowOS

Others partially prevented boot or responded incorrectly.

I logged into my android head unit using my google account (gsuite) and was forced to setup a screen pin lock.

Now every time I start the car it boots into the Lock Screen and there is no way to remove it, I removed the account and it still shows there.

Even when I disable google smart lock and find my device it gets automatically enabled after reboot.

Anyone know how I can get the screen lock menu again it doesn’t show in settings/security but it disappeared.

I hope someone can help

[Android Head-Units] Breeto:
Did you ever find a solution to this? I'm having the exact same issue.
[Android Head-Units] mustafer2020:
Yes i removed it in the end

from the play store download shortcut maker, you can create a shortcut for anything on your android device or search all the plugins and modules.

Search for pin or passcode or screen lock and it will show you all the apps that have that word in the menu including System settings.

Create the shortcut, and keep trying until you find it.

Once you find the right menu run it and you will get that menu again and disable it.

the shortcut maker application will let you find hidden menus that you can’t access on your screen

if you are still stuck I’ll send you a photo of the shortcut I created
[Android Head-Units] Breeto:
Thanks for the reply. I ended up getting it fixed using a similar method.

I used Nova Launcher to create an Android activity shortcut/widget on the desktop.

It took a lot of scrolling and trial and error, but in the end the activity that got it done was called .password.ScreenLockSuggestionActivity.

Thanks!

[Android Head-Units] Wopcore:
I just figured out how to fix this, and deleting Credentials and disabling through the regular settings menu does not work. I downloaded an app from the Play Store called Android Settings X. There you can reach the hidden settings. Choose "Choose screen lock (SetupChooseLockGeneric)" to remove the Screen Lock. Bam, fixed!
[Android Head-Units] Wopcore:
If that option doesn't work there is another one, 2 options down, called "Settings (ScreenLockSuggestion)". This is the only way I know of that actually removes the Lock Screen and will not revert back.

My issue with screensaver is when I first start the unit the first time I use a SWC it turns the screensaver on! Only does it once and then it is fine and SWC function as intended until next time the unit is restarted. I dont think it is an issue on android end as I have the screensaver turned off in there and when turned on it looks different, I think it has something to do whatever settings there is in the headunit as it has an option for screen saver to be: screen off or customize (which is a clock but no options to customize...)

I cant find any information on how to fix this issue anywhere and it seams I may have bought a strange android stereo (B200?) as I find all information I find is irrelevent and looks different to how mine is.

So it looks like my option is now to use Odin and update it. Can I update it to just the latest firmware? Or do i have to do each one in order (i hope not cos that will take a long time!) It also sounds like I need to make my U into a U1? that gets rid of any bloatware?
