1. HOME CSC does *not* wipe the phone - the other one does wipe it. Wipe is required when going between U and U1

2. Yes, the North American S20 models are all still on bootloader 1

3. Yep, the rest sounds fine. There's no reason that U1 shouldn't work for you - for updates or anything else
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] alirz:
Cool thanks. So Just to clarify and for my understanding.

All s20+(the snap dragon models) are the same hardware wise. I.e have the same hardware to support all network bands for 4G and 5G.

But me currently being on a W fw(canadian) l likely have some network bands disabled or not being used now that I'm using a t mobile sim card? Moving to U1 should help. Right?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. All the North American models (U, U1, and W) are the same, yes. There are other Snapdragon models which are NOT the same, hardware-wise

2. Yes, flashing U1 firmware should enable all T-Mobile bands which are supported by the hardware

Hello all. I have an S20U and was thinking of going back to U1 firmware. I was wondering if I can flash this latest build even though the CP and CSC is different. Will that affect anything or cause an issue while flashing?

AP: G988U1UES1BTJ3

BL: G988U1UES1BTJ3

CP: G988U1UEU1ATG2

CSC: G988U1OWA1ATG2
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Where did you get the firmware from?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] yeltrah123:
I just downloaded it from Sammobile's website under firmware for "SM-G988U1"
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
SamFirm reports the same CP and CSC, so yes, you can use that if you want
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] yeltrah123:
yeah the CP and CSC are the same, so it doesn't matter that the AP and BL are different (1BTJ3 vs 1ATG2) correct?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
No, doesn't matter. It's rare to see a release like that - 99% of the time, all 4 files will be named/numbered the exact same way. But it happens once in a while

Hi Guys, I have the US S20 Ultra version "SM-G988U1", but I'm using it mainly in Europe and I'd like to have the e-sim function, which requires other ROM and FW. Can you please share which ROM version is the best one and is it possible to flash via ODIN w/o losing data?

Thanks!
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] alirz:
So wanted to confirm something. I had converted my G986W(XAC) to G986U1(XAA) about two weeks ago. I had flashed the G986U1UES1BTIG fw. Using a TMB sim card in the phone. Current CSC shows TMB/TMB/XAC.

However i see G986U1UES1BTJ2 (XAA) came out yesterday according to Sammobile site. But when i check for software update in the phone, it doesnt pull that update.

Question: My OTA should be working with my current software but should I be on the U1 or TMB OTA schedule?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Both.

Your device is U1 and your CSC/region is TMB. So your device isn't going to pull an update that was released for XAA CSC/region, because you don't have that CSC/region.

U1 devices with TMB CSC/region got TJ1 - it started rolling out about 2 weeks ago. So if you check for updates, that's probably the version that it will pull

In other news: neither SamFirm nor Frija seem to be working at all today. SamFirm gives "authorization failed" message. So I wonder if they've closed the route to the firmware database on the back end. I don't think I've ever seen this before
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] alirz:
ok so this is where my confusion comes from. I am running the U1 firmware. I simply have a T Mobile sim card. Now does the U1 fw have the CSC in it? whatever that means implies. I dont have the T mobile logo or TMB bloat on my phone.

I had manually flashed the latest U1 fw about 3 weeks ago. (BTIG, OCT 1 security patch).

So again, what does this mean for me? Will OTA not work on my phone with the current fw/CSC im running? How can i put myself on the TMB or U1 firmware release schedule without having to run the actual TMB fw with all the bloat etc....Thanks

EDIT: note that my device's original CSC is XAC. I have flashed it with the XAA firmware.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
You're already on that schedule. You don't have to do a thing

[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
"AT&T version" would mean U firmware

"XAA" would mean U1 firmware.

So it sounds like you're contradicting yourself. I'm not understanding which one you want to flash
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] itchyUnder:
In Odin, there are 4 components to flash, including the csc or home csc. I am wanting to flash the branded (Android 10) csc to keep the carrier features while using the u1 unbloated version (Android 11) for the other components.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
All U firmware pieces are identical, for each build - no matter which carrier it's from. So there is no such thing as an "AT&T CSC". So you can flash the CSC from any released build of Android 11 U firmware, combined with the rest of the files from any released build of Android 11 U1 firmware.

Which CSC rom should I install to get OTA updates?

Please Help.

Thanks for help
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Well Android 11 just came out, so you're obviously not going to know if you'll now get OTAs or not, until a new version is released. Once the next update of Android 11 is released, if you haven't gotten OTAs after a few weeks, then AT&T is probably preventing you from getting them, and you'll always have to manually update

G988U1 CTKJ just dropped with December security update as well!!
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] robcop19:
From what I can understand, the correct way to swap would be to flash the SM-G988U1 region XAA firmware from Frija 1st using Odin (3.14.1 patched), wiping everything by checking CSC (I don't see HOME-CSC) but no USERDATA, do the sim card carrier install, and then re-flash SM-G988U region TMB/TMK firmware w/USERDATA?

If this is correct the only thing I waiting to figure out is if I should use TMK or TMB, though I'd love to be able to keep all my apps and stuff instead of transferring and setting it all up again.

PS - Does anyone know if there are any significant differences between the TMK (metropcs) an TMB (t-mobile)? I just bought a Verizon S20U, plugged it into my MPCS , and really have been dying to switch it to either one to get rid of VZWs bloat and whatnot. I've been out of the root and flashing game for like 8 years so I feel like a newb again.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] itchyUnder:
That's how I flashed my current setup, mixture of u1 and I.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Metro has never sold the S20 Ultra, so no Metro USERDATA exists for that model. You'll have to go with T-Mobile firmware
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] denpad2010:
I have a Verizon s20 Ultra, that is locked, I know flashing the U1 firmware won't unlock it, but I thought it will be something similar with previous models, example, I had a Verizon s10 5g version that asked me to contact customer service to use another service provider, I flashed the att firmware and boom I was ready to use it with any service, in my cause I use tmobile, so I did same with this s20 Ultra, works for a few minutes then unlock code message pop up, and I dismiss but phone won't work, do you know if there a way to unlock it with flashing firmwares like I did with the S10 5g???
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
No. That's a loophole that only exists with the S10 5G. I can provide a recommendation for a professional business to do the SIM unlock, if needed

[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] robcop19:
So I did the 1st flash to U1 and it passed (non-HOME) rebooted and put in my Metropcs Sim but i cant get the carrier settings install to come up like I did when i first bought it. Also, the device software still shows VZW VZW VZW but it does show its a SM-G988U1. Shouldnt it have changed to XAA XAA TMB or something not VZW?

*Even Odin mode still shows *carrier Verizon

With that aside, I tried then switching to U TMB firmware anyway, but now its failing and wont go through
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
If you mean that you don't see the popup to install the new carrier settings, idk if I've ever NOT seen that, on U1 firmware. So that's kind of odd. Which U1 build did you flash?

Did you have a SIM inserted when you did the flash? That may be why the service provider codes didn't change

And in order to diagnose why the U flash is failing, we need more detail
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] robcop19:
Ahh I did leave my metro sim card in while flashing. That could be be it

I downloaded the latest U1 XAA from Frija and same for the U TMB.

If I try again tonight, flash the U1 firm without a Sim in it, then turn it on, and then install the sim? I've had it come up just popping it in without turning the device on so that's how I've been trying it

I tried the U TMB firmware after flashing U1, included the USER DATA and non HOMECSC, and when it restarted, the Verizon bloat came up and carrier info

I just flashed back to U1 for now
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
The Verizon bloat came back because you never got that popup. But remember that even if you had, you'd probably still get Verizon bloat. I think a T-Mobile SIM would need to be inserted after you flash U1, and then flash T-Mobile U + USERDATA, in order to get T-Mobile bloat
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] robcop19:
Good idea, I'll try again with the metro sim out and insert it after flash and booting U1, since I don't have a t-mobile sim and it came up the 1st time.

If not I'll go buy one and try before flashing the U + USERDATA

ok so i had recently updated my originally XAC s20+, but i had been running the XAA Android 10 fw on it for few months on t-mobile. OTA updated to Android 11 few days. All has been fine.

Today decided to do a re-flash as i wanted to start fresh. Using Frija, auto downloaded "SM-G986U1_10_20201201141

035

_064p4luguk_fac" XAA CSC. Flashed it, all fine except that i ended up with some Purple themed BTS edition phone. Had to google WTF that was.

Anyways, redownloaded fw using manual settings. "SM-G986U1_1_20201127100

433

_iecnqh4r70_fac". Trying to flash it using moded Odin 3.14.1. However it gets stuck at flashing "super.img". Tried, to flash few times, re-downloaded, even tried flashing that BTS edition fw that had worked. But no luck . Now im stuck with a dead phone that wont boot. Goes into emergency recovery mode but i can still get it download mode, start the flash but still end up getting stuck at super.img..

Any ideas, would really appreciate it!!!!

Message on phone screen shows " Partition super", Reason SUPER Build-id does not match with the reference

(SUPER) :CUSTOM, BOOTLOADER : 36238503

NOTE: not sure what that custom bootloader message means,. i ve ever flashed anything but stock fw imaged on the phone ever.

Wondering if i should try the NAND ERASE or the -re-partition options in Odin???

Just tried a coworkers TMB sim but i still did not get apply carrier settings. I flashed U1 4 times and inserted the sim card at different times to try and get it. I installed it after the full boot into the home page, then installed it at the start screen (setup), then I tried installing it when the samsung boot logo comes up, lastly i installed right as the phone rebooted and still i cant get it go off of VZW/VZW/VZW or get the install carrier settings. I feel like its a verizon thing.

ps the bloat does disappear and boot is brandless but no TMB settings or info

Edit: I tried a couple other combinations of the order of sim insertion, long wait, factory resetting ( ive been flashing for about 4 hours this morning) but i cant get the csc to change off of VZW.

So for now, I'm just leaving it on the U1 (VZW/VZW/VZW) and at least the bloat is out.

[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. You don't need an unlocked bootloader to flash official OEM firmware. That holds true no matter which device it is. You only need an unlocked bootloader to flash unofficial/custom firmware.

2. It's basically impossible to brick a Samsung phone, especially if it has a Qualcomm chip. There are too many safeguards in place
