Question S21 Ultra SC-52B Questions - Samsung Galaxy S21 Ultra

So, I have an S21 Ultra running Android 13/OneUI 5.0, it is an international model from Japan known as the SC-52B (I think also may be referred to as SM-G998D?). The reseller on eBay listed it as "unknown carrier" but I did not expect it to come as a non-US variant, though everything does seem to work except 5G due to the correct bands being disabled. I can't find much info on SC-52B online, I know it has the Snapdragon 888 but no idea if it's any different to flash/program, or if I am just not doing what I need to do.
First, I was trying to flash USA U1 (stock) firmware to remove the bloatware but no luck, Odin gave me a "re-partition" error and some google results said this could be due to incompatible firmware. Sammobile does have firmware matching this model but they are all Android 12 and have the same carrier software I have now (Docomo). I assume I am probably out of luck on this conversion, I did read some info on changing CSC first but not sure if this will actually fix it.
Second, I am trying to unlock the correct bands for 5G operation on Verizon, and I found that Samsung Toolkit can do this as well as some ADB commands. From my understanding, this works on UI 5.0 but not 5.1 due to a patch from Samsung. I have 5.0, but I am getting the same issues as those with 5.1, and going via ADB does not bring up the hidden Service Menu either.
Lastly, is there any way to change the boot logo without root? I just want the normal Galaxy boot logo instead of this "DOCOMO" one, which I do understand would be achieved IF I could get the USA firmware loaded, I just don't want to brick it.
Just curious if anyone has any ideas or suggestions, or should I just trade this in on an S22/S23 Ultra? I only paid $300 and Samsung would offer $600 for trade-in, which is nice alternative but a $300 fully working S21U would be preferred. Seller does offer returns so I could also just look for an actual US S21U.

Question about U vs U1 variant before I sell

Hello,
I am planning to sell my Sprint Note8 online soon. I have the phone unlocked (and confirmed that it works on AT&T with a friends SIM). My question is that I'd like to advertise it as just the North America Unlocked version to reach a larger audience and hopefully get more money. I am pretty sure there are no hardware differences between the N950U and N950U1 variants. So my thinking is that if I Odin flash the XAA N950U1 unbranded firmware onto the device then it would be identical to a phone straight from Samsung. That said, I'm not 100% sure and of course I don't want to falsely advertise. Can anyone conform for me whether I am right or not? Obviously I will market as "Sprint - Unlocked" if there are any differences at all.
Thanks
I think it would be safer and better for the buyer if you flash whatever Network they want before you ship it.
don't update this app!!

Be sure to follow the switching carrier guide to change code to specified carrier to get rid of lingering Sprint stuff if you want them to have true stock experience...if you change carriers, that is...even if you do xaa

Importing a Snapdragon Model from U.S.

After comprehending the HUGE differences between the performance of the Exynos and Snapdragon model (thanks to Anandtech and Gary Explains YouTube), I am thinking of buying the Snapdragon model from U.S. and importing it to India. Wanted to know wether or not is it worth it, the hassles of doing so, and is there a better option than Amazon for it ?

I would strongly advise not going down this route. I did the exact same thing with my previous S8. What Samsung don't tell you is that they include a region lock on their devices. In order to remove the lock, you need to use 5 minutes of call time in that particular country to unlock it. I purchased my phone in the US and initially and used the phone to get the unlock, without any knowledge. The issues arose when I brought it back to the UK and flashed my own firmware. In this case, a beta firmware update. By doing my own flash, it then reset the lock removing access to the galaxy app store, samsung pay and a number of other apps.
You can find an example of this by simply googling samsung region lock.
If it's simply a performance issue, I would stick with the Exynos processor. My note 9 has had no issues in performance whatsoever and would strongly recommend the phone.

Thank You AFewLads for bringing this issue to the fore and potentially saving me a lot of money !!! Btw, just for my curiosity (and probably a few others), what did you do with your S8 then ?

Unlocked vs Carrier s10

I currently use multi-line setting for my virtual number (Digits from Tmobile) and would like to continue using it for my future s10+. I'm tempted to go unlocked but I just don't know the difference.
I also heard about slow updates for unlocked? Is this true?
What's the advantage of getting one or the other?
Unlocked will have root + unlocked bootloader. It will run on Exynos. Tmos version will have Snapdragon and be completely locked down with no root.
Sent from my Pixel 3 XL
I'm sure the US unlocked will be the Snapdragon just like the Note 9, exynos will be international. The unlocked version will see updates last after carrier updates according to Samsung this is because unlocked has to work on all carriers.
I tend to buy unlocked phones as they re-sell better and quicker
I always buy the US unlocked version (Snapdragon). No bloatware and I'm not tied to one carrier. I can change to the lowest cost month 2 month service any time I choose. No contracts.
Does this means that if I buy S10 locked to a carrier I will not be able to root my device? (assuming I buy the version in exynos)
Has anyone had success using unlocked Samsung devices with Xfinity Mobile (who does not currently support bring-your-own-android)?

Lol, oh there's bloarware, like two of everything...but yes, no added carrier bloat. That would just be unbearable.
As far as I'm aware, all the recent US variants of Samsung Galaxy phones, including the factory unlocked variants from Samsung, have traditionally come with locked bootloaders. It is likely this is true for the S10 as well.

The built in multi-line setting is normally available with T-Mobile branded phone, such as S8 and so on. Unlocked model didn't have multi-line support, but you can always download their digits app. If you don't want the app, then you would have to flash your S10 with T-Mobile firmware and get all the features and I do prefer to go with this route as you won't get T-Mobile's bloatware

Is there even word that we can even use Odin to flash another firmware on to the S10 like the S8 and 9?
T-Mobile is offering a hell of a better deal on the S10 than Samsung directly with both the monthly payments (if you choose that option) and a better S8 trade in amount at $390 versus $330. It might tempt me to go that route even though carrier bootups and firmware labeling annoys the hell out of me. If it's still possible to flash with Odin, buying from a carrier would be a no brainer. Flash off to the unlocked firmware if you want better rates, and then flash back when you want something on the firmware side.
If its the case like the Note 9 and the S9, then even though you buy the unlocked version, once you pop in the carrier sim the phone will reset to that carriers CSC profile including all the bloatware and apps etc... Change to another carrier and the phone will switch profiles accordingly.
Please correct me if im wrong.

Odin firmware flashing was possible on previous recent Galaxy phones, including the S9 and the Note 9, so I hope that is still the case with the S10.
If it is not, then honestly I would rather just buy the unlocked version based on principle alone: If I'm buying a phone at full price, then I would rather not buy one that is stuck with a particular carrier's firmware or branding. It's a Samsung phone, not a "TMobile" or "at&t" phone.

When I was preordering S10e, I was at two roads: T-Mobile variant or unlocked, but it didn't take me long to realize that unlocked would give me more flexibility.
When you flash unlocked unit, it is just a standard flash: using Odin pick a carrier firmware and flash. When you flash a carrier branded phone, in most cases
you would needed "factory binary" firmware because you would need to change CSC(unless your carrier phone was multi-CSC) to the one you need, than in the dial, type some commands to pull up CSC changing menu and after saving and restarting phone, then flash a firmware of your choice In other words it was a longer process. That I why unlocked phone would just be a regular flash and a fast one.
I can't guarantee that there will be a way to flash S10, but most likely it will be possible to do it. I even flashed Galaxy S3, S4 and so on.
I think couple of years ago Samsung made an unlocked firmware that would detect which sim card is inserted and tune the firmware to that sim, but to what extent, I don't know
Also unlocked phones mostly are approved for Samsung beta testing of new Android built(if you are into this)

The Snapdragon unlocked, U1, is only sim unlocked, not bootloader unlocked.

I'm wondering... regarding changing the CSC if flashing from a carrier-specific firmware to the unlocked firmware, is this the equivalent of needing to use a patched Odin that bypasses CSC match check? I've never actually done this process, but have been reading about it.

The last phones I flashed was my unlocked S8 and Sprint S8 Active.
So when I flashed my unlocked s8 to T-Mo firmware, I just used regular Odin because unlocked phones have multi-csc codes for many different carriers.
When I needed to flash back to unlocked XAA csc, then I had to use modified Odin and flashing completed successfully.
With Sprint S8 Active model, I had to jump through few hoops and it wasn't pleasant as at the time of my flashing, most people had other phones and no special "factory binary" firmware was freely available.
I don't recall exactly, but: I took Odin(possibly regular) flashed with special factory binary firmware which had the ability to change csc codes to the one I need, then it would restart my phone, than I think I used modified Odin to flash the final firmware of my choice. I wanted to convert Sprint model to T-Mobile

Galaxy S10 5G SM-G977N

Hi,
I bought this off Gumtree and unbeknown to me it was not the UK version. Is there anyway to flash this onto the UK firmware and get rid of the korean apps etc? If I click a number even thought the dialer is set to system it pops up a Korean one which it then states is not supported.
Thanks
Why did you choose this model ?
I think there is a different model released for Europe? G977B if I am not wrong!, the issues you mentioned could be resolved by away or another but you will not be able to activate the 5G capability of the device!. furthermore, as far as I know, no one has proved successful flashing of other models firmware to this Korean model!.
If 5G network is not important for you, then you may be able to customize the phone to meet some of your required customisation.

When I bought it I didn't know it was not the UK model. It's only when you use it more that the differences come up.
My situation might be similar to yours!. however, I was somehow aware of the model and it's possibly shortcomings!, but I was able to modify a lot of features until it becomes almost whats I want except the ability to use 5G feature!.
BTW: Although the phone is KT oriented still you can use it and do some changes that meet your local settings. nevertheless, ultimate changes/customization could be achieved if you can root the device and install custom ROM.

Question Anyone have U1 XAA 5BULH?

Short story long, I was on U1 XAA 4BULE, and I've been having major issues with app crashes (specifically DJI GO 4 for my drone) and I was going to downgrade to 4AUIP (Android 11 One UI 3.1). I downloaded the firmware, patched Odin, flashed the downgrade, failed, phone won't boot.
Turns out, my phone auto updated on reboot (I forgot to disable that in Developer Options) so it automatically updated to 5BULH, and now that it's on the baseband 5, it can't be downgraded to any baseband 4 firmware. So, easy enough right?, just flash 5BULH? Well, as far as I know, that was ONLY released as a baseband PATCH in the form of an OTA, and there's no actual firmware as far as I can tell.
Which basically means my phone is bricked until Samsung releases an actual 5XXXX firmware to flash with Odin.
I've been looking for awhile, checked Frija, SamFW, GalaxyFirmware, SamFrew, SamMobile, SamFirms, FirmwareX, and Sfirmware all with no avail, every latest firmware that shows is 4BULE
Unless someone has a baseband 5 full firmware for Odin, because I couldn't find anything online, than I guess I'm screwed until *5CVAA comes out, which is rumored to be on February 9th during the S22 launch event.
So, anyone have that firmware? Or am I just going stone age until February 9th when the new build is suppose to be released?

Bummer! That's a genuine horror story of I ever heard one!
Tried searching for said firmware, but couldn't locate one anywhere.
It's either stone age for you or just pop into a service center and have them flash the phone for you. From what I can see you only tried flashing stock firmware, phone should still be under warranty...
Wish it was that easy, population of 98k in a town that is roughly 750km (~470mi) away from the next major city means a service centre doesn't exist for me lol. Purchased through a Carrier also requires an additional $15 monthly charge for warranty outside of Samsung which I obviously didn't pay for lol. Plus with shipping times around here (Amazon Prime shipping takes a week minimum), just to send the phone to Samsung for repair, I would be looking at close to a month there and back. Looks like I'm just better off just waiting for estimated 10 days until the 5CVAx/5CVBx firmware to be released.
I dusted off the old Windows Phone, it'll do for now I suppose. Hopefully they release something before February 9th haha
Thanks for looking around for the firmware.

The programme says it can't connect to a USB File Transfer device when in recovery, and when booted in Download Mode, it says to open the recovery procedure, which asks for a recovery code from a previous OS install. Which I don't have because I've never used this before. So, looks like it needs a previously working instance before it can be used for recovery.
Also, entirely unrelated, but I made a video of my friends car with that quote in your signature haha

Learned quite a few things today.
Samsung just released 5BVA1 for G998W. So I switched to that just so I have a phone. (I usually stay on U1 for faster updates which apparently isn't the case anymore)
It turns out that 5G is also working in my city now that I'm not on U1.. So for some reason Canadian 5G doesn't work on U1 even though they use the same basebands which is weird. It's like Bell is blocking non W phones from using it even with all the correct APN settings.
It's also pretty interesting that even on G998W XAC (unlocked Canadian CSC from Samsung with no bloat apps), it now says on setup "looks like you're using Bell, restart the phone" (with no way to close it, or ignore it) and after rebooting, it forcefully installs all of the Bell bloat apps as System apps that can't be uninstalled unless using ADB.
So there's literally no reason to buy a phone directly from Samsung now, at least in Canada. You get the carrier bloat apps by force no matter what with One UI 4.0 Might as well just buy them from the Carrier with the discounted prices for a 2 year term.
S21 Ultra from Samsung for Canada was $1999.99, though Bell it was $350 up front plus $50 a month for 12 months, works out to $1550. You literally save $450 CAD by getting a phone through a Carrier. Only reason to buy from Samsung was for the limited edition colours, and so the phone didn't have bloat apps preinstalled from the carrier. And personally, it's not worth $450 since you get bloat apps no matter what now, only for a special colour when replacement back panel which are like $60 CAD off eBay if you REALLY wanted a different colour lol
U1 XAA still doesn't have the bloat apps, but 5G doesn't work in Canada.
So it's either W XAC with Bloat and use ADB to remove it. Or U1 XAA with no bloat, but no 5G.
My phone is now working again, but those are some interesting findings, use this information as you will.

Where did you find that 5BVA1 ???
Frija
Searched for SM-G998W XAC, it get's firmware directly from Samsung's servers so it'll always find the latest version Samsung has up.
I have it on Google Drive if you want it from a different mirror, or if you can't get Frija working cause it depends on Visual C++ x86 2008 and 2010 and even then it fails to load on Windows 11 sometimes which is why I stayed on Windows 10 lol.

You could flash the U Firmware as well. It's up to #5 BL. I'm not sure what your limitations would be, but it's worth a shot. It's 5BULJ.

Turns out, my phone auto updated on reboot (I forgot to disable that in Developer Options) so it automatically updated to 5BULH, and now that it's on the baseband 5, it can't be downgraded to any baseband 4 firmware. So, easy enough right?, just flash 5BULH? Well, as far as I know, that was ONLY released as a baseband PATCH in the form of an OTA, and there's no actual firmware as far as I can tell.
Which basically means my phone is bricked until Samsung releases an actual 5XXXX firmware to flash with Odin.
I've been looking for awhile, checked Frija, SamFW, GalaxyFirmware, SamFrew, SamMobile, SamFirms, FirmwareX, and Sfirmware all with no avail, every latest firmware that shows is 4BULE
Unless someone has a baseband 5 full firmware for Odin, because I couldn't find anything online, than I guess I'm screwed until *5CVAA comes out, which is rumored to be on February 9th during the S22 launch event.
So, anyone have that firmware? Or am I just going stone age until February 9th when the new build is suppose to be released?

Just to let you know: BULH standalone for U1 has been released on SAMMobile
On Frija as well. Usually a faster download there.

Learned quite a few things today.
Samsung just released 5BVA1 for G998W. So I switched to that just so I have a phone. (I usually stay on U1 for faster updates which apparently isn't the case anymore)
It turns out that 5G is also working in my city now that I'm not on U1.. So for some reason Canadian 5G doesn't work on U1 even though they use the same basebands which is weird. It's like Bell is blocking non W phones from using it even with all the correct APN settings.
It's also pretty interesting that even on G998W XAC (unlocked Canadian CSC from Samsung with no bloat apps), it now says on setup "looks like you're using Bell, restart the phone" (with no way to close it, or ignore it) and after rebooting, it forcefully installs all of the Bell bloat apps as System apps that can't be uninstalled unless using ADB.
So there's literally no reason to buy a phone directly from Samsung now, at least in Canada. You get the carrier bloat apps by force no matter what with One UI 4.0 Might as well just buy them from the Carrier with the discounted prices for a 2 year term.
S21 Ultra from Samsung for Canada was $1999.99, though Bell it was $350 up front plus $50 a month for 12 months, works out to $1550. You literally save $450 CAD by getting a phone through a Carrier. Only reason to buy from Samsung was for the limited edition colours, and so the phone didn't have bloat apps preinstalled from the carrier. And personally, it's not worth $450 since you get bloat apps no matter what now, only for a special colour when replacement back panel which are like $60 CAD off eBay if you REALLY wanted a different colour lol
U1 XAA still doesn't have the bloat apps, but 5G doesn't work in Canada.
So it's either W XAC with Bloat and use ADB to remove it. Or U1 XAA with no bloat, but no 5G.
My phone is now working again, but those are some interesting findings, use this information as you will.

How do you find the phone after the update? Issues with lagging? How is the battery life? I had to downgrade back to 11, I found the earlier firmwares too beta-like for daily use.
