Ok, I bought it refurbished from Amazon.

But so, you confirm is better the firmware U/XAA?

Anyway, I don't have the option "Unlock OEM", I deduce that the bootloader is locked as all the U/U1. But if you say someone flashed U1 on it, my bootloader is supposed to be unlocked so?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
No, your bootloader is not supposed to be unlocked. Whoever told you that doesn't know anything about bootloader unlocking
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] mcssym:
Thanks. And you confirm it's better for me to put SM-G981U // XAA?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
First of all, XAA belongs to U1 firmware, not U firmware

Second, what's the current phone's Baseband Version? (And don't do any software updates, if it asks you for one)
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] mcssym:
1. Ah ok, so if I use a U firmware, what is the CSC?

2. G981U1UES2DUH2, and sorry, but trying a method to get OEM Unlock at the beginning, I did all the updates till September 1st. Can't I downgrade?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. U firmware is universal. It doesn't matter which CSC you use, since they're all the same

2. No, you can't downgrade. If you had an older version, then the bootloader would be unlockable via paid services. But since you updated, never mind.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] mcssym:
So, even with paid services, I can't unlock the bootloader?

If I don't update more, do you think in few weeks this will be possible?

Putting the U firmware can resolve it but I need the bootloader for that, right?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. No, you can't unlock the bootloader no matter what

2. No, I don't think it will become possible in a few weeks

3. Putting U firmware will resolve what, specifically?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] mcssym:
If it's not in few weeks, in few months?

When I say U firmware resolve this means if I can put an older firmware, then I can unlock the bootloader?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I already told you that you can't downgrade

Good evening everyone here I bought a s20 ultra 5g version g988u1 and I live in France and I do not have access to 4g or 5g my network goes up to H + or 3g
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Then your provider probably uses 4G and 5G frequencies which are not supported by that model
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Ken973:
hello and thanks for responding. Is there a solution to my problem?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Yes. Buy a different model which does support the 4G and 5G frequencies of your provider

I bought a SM-G981U from T mobile.

Received the phone, unlocked it within android.

Flashed the SM-G981U1 VZW firmware from Frija/Odin patched 3.14.1

All works well and we have no Verizon apps.

Unfortunately, no voice mail app and others.

Any way to flash the SM-G981V user data to the phone from Odin? Or will that cause issues?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Nope, it'll fail if you try
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] big_sea:
What should I flash to get hd calling and voice mail back?

Should I do the SM-G981U1 and XAA country code instead of VZW?

You can try but no guarantees

Hi,I'm debating on getting this U1 version over the OnePlus from China (mainly, as I would like to stay away from Chinese products as much as I can).

However, since I'm located outside of the US, I wonder how good it'll be.

Plus,

Anyone knows if Samsung plans to keep on supporting this model or it's going to be outdated in no time?

Cheers,

M
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I don't know off the top of my head but I'm sure a Google search will give you the details on how long Samsung plans on supporting the S20. Standard practice is about 3 years though, for flagship models
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] ForMartha:
That's the case. you are correct.

One more Q if I may. How does the camera compare with the Nord 2? The camera sensor is one thing but the ISP on the 865 should be better comparing to the MTK Dimensity 1200, What's your take about it?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:

@iBowToAndroid

Hello this is long shot but I'm hopeful to get a reply

I just got an S20

Model is SM-G981U1

Build is RP1A.200720.012.G981U1UES2DUL2

Baseband is G981U1UES2DUL2

It's on XAA

I have two questions

1. On a search using the IMEI, result shows G981U on T-Mobile and BLACKLISTED, I don't live in the US and local sims works fine. Will there be an implication because of this blacklist?

2. Will I get OTA? and if I do and update, hope I won't get sim locked back to the original T-Mobile

Thanks
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. You just said a local SIM works fine in the device. So I'm assuming the USA blacklist status has no effect on it

2. I have no idea if you'll get OTAs. You'll need to wait and see
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Kokatrends:
Yes I got the latest One UI and Android 12 update

[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Gwumex:
I get this when i try to change my csc from XAA to SPR, I live outside the US. I'm changing this because my phone doesn't receive OTA update,

my current security patch is FVF1 and csc is in this order XAA/XAA/SPR
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Why change the CSC? Just manually flash firmware in Odin

I just activated a s20 Tactical edition unlocked version and using on a t-mobile sim for service, so how long will it take to upgrade from android 10 to 12. Or will I have to do manual update since the "update software" doesn't do anything. Last installed software is dec 2020. I'm old vet and need to keep it as simple as possible for updating. thanks
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I've never heard of an "S20 Tactical Edition". What's the model number of the device?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] csmdew:
On phone SM-G981U1 and on box says SM-G981UZAATTC. Also on ph when startup it say tactical edition which is a valid edition designed for military. Problem is I can't get it to update from date it was put in box. Got tired of waiting for ota and tried the odin which said pass but never upgraded. Got i to say pass 4 times but still on And 10 and old security update 12/20. Just want it to update especially the security part. Thanks

Smart switch says this mdl does not support firmware upgrades; so fine if it doesn't upgrade from android 10 but does that mean it also will not get security upgrades.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:

1. The purpose of pictures or screenshots isn't to change any info. It's to show us all of the applicable details on that page

2. You take a screenshot by holding Volume Down and Power together at the same time
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] csmdew:
so if i do that it takes pic of page i'm on, right... 74 yrs old so not great with phones

didn't work, tried 6 times, just vol dn or pwr off

Ok, so just got off phone with samsung support and since this phone was built for the US gov and has top secret encryption software they can not update the software and it is not supposed to be sold on open market. Since it's more secure than regular phones I won't worry about the updates. Not likely to get hacked. Thanks for help.

But I still don't believe it can't be hacked to load firmware.

after the vk1 update, my radio goes really bad. i have connection and then it drop the signals, and then it goes to no service, and that keep happening.

Google Fi is my service provider and after the sent me the new SIM and bug report inspection etc, they told me to reach out to samsung.

my ODIN expertise is quite rusty now, but back in the days on S2 we had just the radio flash, is that still a thing?

I got the latest ODIN 3.14.4 but not sure where do I grab the official ODIN firmware binaries from. is that sammobile.com website?

the phone was working fine after the initial activation, but phone wasn't updated since 2020. so I am not sure which update break the radio.

any help would be appreciated.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
You can use SamMobile if you want, but download speeds are extremely slow, unless you pay for a premium membership. SamFW.com has very fast downloads, or you can use the Frija tool
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] byteless:
Thank you. Frija tool seems really helpful.

where do I get the CSC code?

I have S20 5G samsung unlocked version
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
From your phone's settings
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] byteless:
Thanks again. its XAA

is there a UI5 beta update that I can download and try?

any sammy website lists all the released updates?

I have to use the manual Frija mode and need to plug in "PDA" "CSC" & "CSC" to grab the older odin binary
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. Android 13 is now rolling out to many models in stable form. There are no more betas

2. SamFW.com lists all of the released updates

3. Frija will only ever give you whatever the newest/latest version is. For older versions, you need to visit a website like SamFW that hosts all of the firmwares

There will be nothing going in userdata selection for this?

Where does frija download the file to; just downloaded but don't know where it is.

never mind found it in pictures

Did u get it to update and if it was TE then it would show S20 5G Tactical Edition on start screen. A guy on offerup has been selling a lot of them and they just won't update. Switch app says no updates for this unit.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] byteless:
Couldn't updated. If just doesn't detect the device after I reboot on bootloader.

I also find out that once it is updated. There is no rollback

I have U1 if I flashed U that takes away my Sim Unlock doesn't it?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] byteless:
I am not able to flash it. it just doesn't detect after reboot into bootloader so odin not able to push.

My problem is the new update VK1 broke my radio.

After putting the SIM, it try to connect for few min and then signals drops and then it shows emergency calls only.

I am thinking that maybe radio broke for my s20 on this update so maybe rolling back would fix the problem
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
U1 firmware doesn't have USERDATA, only U does

It downloads it wherever you tell it to. After you click Download, Windows Explorer should pop up, asking where you want to download it to

They might not update via OTA, but manually updating should be fine

Well that's because flashing isn't done via the bootloader. It's done via Download mode

Nope
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] CharmedWhovian:
Another question; The S20 5G isn't getting Android 13 UI 5 is it? & if not it's it because they don't produce the S20 5G any longer.

Yes it is getting 13, all ready being rolled out.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] CharmedWhovian:

Me too, a few of those sites said that Dec would be when the update arrived. Yet, unless I'm in like China I don't see the firmware.

[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] grantl6:
Hello, I'm having an issue getting the at&t version on my phone. I have an unlocked version but the calling currently doesn't work with a firstnet sim. Whenever I flash the userdata file on the final step it seems to just revert back to the unlocked version of the software, even though the flash went successfully. I have android 12 and am using your android 12 at&t userdata file. The only issue I ran into is that the md5 binary checks failed in Odin whenever inputting the userdata file, I assume because the file was a .tar.md5. Thanks for any help you can provide!
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. You can't just flash USERDATA over U1 firmware - doesn't work that way. You need to flash the entire U firmware, including USERDATA

2. MD5 is what makes Odin do the verification step, so no, that's not why it's failing.

It would still probably flash fine if you remove the md5 extension and just flash it as a tar. But in case you don't want to do that, I'll upload the next USERDATA in the series that I have - and that one will pass md5
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] grantl6:
Understood, thank you. I did reflash to U firmware first, and that seemed to work perfectly. I then flashed the U1 firmware with user data. I just tried again this morning and still no joy, everything passes and looks to be fine except for the md5 failing verification. I did change the file to just .tar but I have a feeling that may have been why it failed possibly, I'm not exactly sure. Thanks for uploading the files
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] grantl6:
Just tried loading the new file into odin, still failing the verification check for some reason. Here's what I'm seeing:
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
The USERDATA that I just uploaded (VF1) passes the check for me. So if it doesn't pass for you, that means it's either a bad download, or bad extraction
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] grantl6:
Understood, I'll try extracting with different software. Was using 7-zip.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] grantl6:
Turned out I had just reinstalled the other userdata, the new one successfully signed, but failed to flash and put it in recovery mode. On the download mode screen it showed SECURE CHECK FAIL: userdata. I'll attach a picture. Luckily a reflash with the XAA firmware fixed it, any suggestions for trying it again? Thanks again for your help.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I already told you:

USERDATA goes with U firmware, not U1.

You can't flash USERDATA along with U1 firmware. You can only flash it along with U firmware
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] grantl6:
I see, when I downloaded those firmware files it was listed as ATT, and the folder is named ATT, but I guess they just slipped an XAA firmware in there.

But you won't be able to unlock the bootloader (and therefore root) unless it's running firmware from February 2021 or earlier
