Is it safe to flash G988W to G988U1 with Odin? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

I got a return label for the Ultra, but still have 2 weeks to return it, I would like to test the update before returning it.
Is it possible to convert the W to ATCH U1 via odin?

Try it

Any luck with this?

yes.. it works.. at least i flashed U1 W and U onto my g981u so other models should work

Have you done it? If so what's the steps to follow? I didn't knew that was possible, I have a s20 ultra G-988U that supposedly is not compatible with cricket wireless, everything works except the call services, it needs to be a G-988U1, but idk how can I change it, hope you can help thanks is advance.

[SM-T837V][Combo Firmware and Stock Firmware Files]

Hello Folks!
As soon as I got the tablet I spent a good few hours looking around for the combo firmware to start looking for exploits so figured I would provide you guys with a link to the firmware for free
It was quite funny actually, after I soft bricked and got stuck in a boot loop I realized I couldn't find any stock firmware anywhere either haha, so I spent a few hours looking for that as well.
I have the Verizon variant, I am not sure if it will work on other USA variants or not as I have no way of trying. With that being said, below will be the links. I will provide a rev1 combination firmware and a rev1 stock firmware as well as a link to a modified ODIN for easy flashing!
And with all that being said, the combo firm is good to bypass FRP. You can enable the oem unlock switch but other than removing FRP it is useless as of right now. You can however, mix and match the firmware unlike my S9+. I am currently on stock firmware with a permissive boot.img for example.
If you got questions or need help, well, you probably shouldn't be downloading anything or flashing haha. But I will try to help when I have time. I do not have any current plans to keep this thread going with updated filese as I had to pay for these. If I can find em free moving forward I will re-upload if I can but I typically stay on the lowest rev/firmware I can until I find a root method
T837VVRU1ARG4 COMBINATION FIRMWARE/FACTORY BINARY
T837VVRU1ARGG STOCK FIRMWARE
MODDED ODIN v3.13.1
If you feel like buying me a beer...​
What is the main benefit of this?
In the q&a section someone wrote it is readily rootable with Magisk. Is that not the case?
@elliwigy
Is there any firmware for the unlocked LTE snapdragon. I got the Verizon version but it's not playing nice with AT&T. Any ideas? Maybe flashing the unlocked firmware would help.

I think it's just the tablet, my Verizon one isn't playing nice with my Verizon service. Constantly not switch towers and losing service when full service is available. Or it's a tower problem but my note8 doesn't do it when my tablet does
Thanks for this, have been looking for a couple days for the build.prop file.
If you get permissive boot, try adb verity disable and mod through push pull adb style like we did on Att note 5

OEM Unlock
I have the T837V and would like to ODIN flash your files, but as you know there is no OEM unlock in the Developer Options on this tablet. Are you saying that you can flash these files without enabling the OEM unlocking?
I would like to install TWRP, but I believe this is not possible without enabling the OEM unlock. Do you know if this is true?
Thanks

Forgive my apparent noobishness but what exactly will that do? Looking for a way to root and wanna know if u have found something I haven't.
Flash firm then what? Does it make OEM show or what? I just happen ta have the most difficult version of the tab S4 which is SM-T837V

I am currently working on a root method with the N9 but it should also work on Tab S4 once all is said and done. I actually found the exploit I use on the Tab S4 originally before I started workin the N9. Nothing is released yet as so far have only gained root on S9 Exynos and I am currently super bricked and waiting for a device replacement lol
Flashing other carrier firmware won't help you unlock any bootloaders or anything nor will it necessarily help you root. Only benefit I can see really in flashing other carrier firmware is say if you have an sim unlocked tablet (we'll say it's a Verizon tablet) and you want to use it on say Sprint. You can flash the Sprint software in ODIN and everything should work. It would be like you purchased the tablet from Sprint essentially.

Switching from ATT to TMobile, questions inside

Hello, I'm currently using a Galaxy s9+ on ATT and plan on switching to Tmobile this week. Besides unlocking the phone do I have to do anything else for the phone to take advantage of TMobile? Do I have to flash TMobile firmware or anything like that in order for the phone to work properly and if so how, I've been out of the flashing game for a LONG time .
No you don't have to flash t mobile rom as I know when you put a new sim the phone reboots and sets the phone up for that carrier that's what it does on my s9 but mine the unlocked one so I got wifi calling with t mobile sim card in my phone
T mobile
The screen shots should show up
same boat but need to flash TMB image
okay hear's the deal, i am in the same boat moved to T-Mobile few days back and i have a Vzw branded S9+. i was of the opinion that things would workout great, but my area has poor t-Mobile network and i have been unsuccessfully attempted to flash TMB firmware on this phone. I have tried just about all combinations, and every-time the flash is done it boots back as a brand new Vzw phone and looks for a Vzw sim. I insert the TMB SIM and things work but not WIFI calling. Any leads?

What odin you use??
1.13.1 patched.
---------- Post added at 02:54 AM ---------- Previous post was at 02:51 AM ----------
Some more details if that helps..
Paid $24 to Sammobil, went through the flashing process and nothing changed. Did this almost 5 times but seems VZW keeps haunting me. Am I doing something wrong? I downloaded the latest firmware RB8 from Aug 2018 for TMB via sammobile flashed the 4 files AP, BT,CP and CSC. Everything went perfect but when it boots back Damn the same old VZW and the OS says u have a non vzw sim. I even flashed the userdata with the other four and separately but no luck. Do we have any success stories and how we dis this correctly? Using Odin 1.13.3 patched version. Tried to downgrade but that failed.
Use 3.13 I believe

Yes sorry typo error, 3.13.1_3B
Not trying to start a new thread with something similar so I'm just gonna post underneath this one. I have an AT&T S9 that is sim unlocked and all but, for the life of me I can't get it to work on Verizon. I've tried changing the bands in the *#*#3696#*#* menu and all I get is, is data. I tried flashing ARG7 unlocked I believe and it still booted with all the AT&T stuff loaded. The build number now shows ARG7 instead of ARG8. I don't know if there's a specific odin / firmware I need to flash in order to be able to get it right. I've been hunting for hours and flashing and I'm at a loss. Thank you guys in advance.

All the carrier stuff is located in the CSC from the flash.
Side note: from what I've read, Verizon locks down the bands and whatnots that stop TMobile stuff from functioning, like WiFi calling.
I've seen people get it working but not the video calls.

There a thread around here that talks about how to get the TMobile services but WiFi calling is all they could get to work. You have to flash the CSC (home partition) from TMobile is what I've heard. I've also heard, you can put in a TMobile Sim and it'll just work. But, I think that might be limited to "factory unlocked" phones.

Read through all the 16 page thread and found very useful comments from you on usage of V3 detonator and Csc changer. I stand confused over just 2 questions;
1. Do I have to root my s9+ which is from vzw
2. It talks about F and FD variant while I have a u variant running snapdragon.

Newbie need help linking S9 to current country

Hi Have s9 G960F in service provide SW ver TEL/TEL/TEL - i beleive austalian telestra,
not getting any OTA updates - currently in Israel
tried google and search on forum, not found something 100% clear
Question 1 : is there any way without flashing new FW via odin to get OTA updates? (vpn, australian sim, fake location and etc...)
Question 2: if answer to question 1 is no, where to get stock Israel FW for G960F , and what is the best option for backup and restore
Thanks!
What is your current SW? According to sammobile the latest build is the BRJ6 (https://www.sammobile.com/firmwares/galaxy-s9/SM-G960F/TEL/download/G960FXXS2BRJ6/246171/) if this one matches your current SW then there's no way you can get another udpate until, I assume Telestra is an Australian carrier, they release it...

In theory yes, but if you don't and they release a newer SW, you can just flash it iva Odin, don't it won't trip a thing nor void your warranty

My best option ALWAYS is Smartswitch, either for backup or SW update, if there's a new SW, Smartswitch downloads and installs it right away
seems telstra rolled out pie update
nothing in the phone, last update june2018

First, the csc is wrong, the link you posted is for Israel, not Australia, and second, once you downloaded the file, unzip it: once it's done you'll have 5 files(as you can see in the picture): AP, BL, CP AND 2 CSC home_ (that one won't erase a thing) and the csc (this one will format your phone)

XT1922-7 Boost to Retail, is it possible?

Hi,
I have a XT1922-7 Boost version, it has been SIM unlocked by Sprint. Now, I no longer use Sprint.
I want to use the phone with T-Mobile or Verizon but there are a lot of bloatware & Sprint-custom settings which is very annoying . Right now, at least on T-mobile, it won't answer call on 4G/VoLTE, it drop to 3G on every call.
What is the best thing I can do? I suppose I can flash my phone to Retail?
I know my phone is Jeter. I might need to unlock my bootloader, flash TWRP, backup the existing Boost G6Play to a microsd card, but I do not seems to see any guide to go to retail, nor I see any Jeter rom to Retail.
Any advice? Thanks

Nope. Sprint Jeter is a different device. Not capable of VoLTE. It's not a retail device. Slightly different chip, different storage, different ram.

You can flash RETUS and it'll work. I've done it. Hell, I've even flashed the RETBR Aljeter firmware and that works too. I just can't get data without a gsm sim card. The bootloader and gpt.bin won't flash, but it shouldn't matter anyways. Just skip them.
Edit: RETUS Firmware.

Yep, retail is for 32gb. I just grabbed the USC Pie firmware a little bit ago. I think that I can turn it into a flashable ROM. I'm trying to figure how to work the modems though. USC will be missing bands, so I'm just going to DD the partitions I need for Sprint/Boost/Virgin from the soak test. I think that'll make it work.

I'm think that's highly probable. There was an issue where a bunch people got Boost models inside generic white boxes, instead of Virgin in proper packaging.

I flashed the US Cellular pie update on my 1922-7 (which I had on Sprint and after my time with them was up they unlocked the SIM slot). It works no problem.
I used it with t-mobile for a week and everything seemed to work fine with it. It also works fine on ATT as well.
Right now it's got a t-mobile sim running Descendant Treble ROM - A only ARM GSI. Works like dream. I never tried VoLTE before I switched from T-Mobile and ATT doesn't offer it in my area.

Same here. I tried it a little while ago. I just can't update my profile or PRL on it, but LTE did work.

Update your device to PIE, unlock your bootloader, flash the newest TWRP build that works with PIE, download the A Only ARM build, unzip it, you should have a system img. Boot to fastboot, fastboot flash system system.img, boot to TWRP, flash this https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389. Boot the rom one time. Then boot back to TWRP and flash pico gapps for Pie. You'll have to get your device certified with google to get google apps to work.

Does this means flash this Jeter? https://forum.xda-developers.com/g6-play/development/ota-moto-g6-play-aljeter-t3921877
Thanks

Flash whatever version of Pie is out for your model. Your Model should be XT1922-? where the ? is a number. For example mine is XT1922-7. The retail US version is XT1922-9 etc
There should be a Pie update for whatever model you have. Flash the correct model and you should be good.

Tried to flash G988W firmware onto my G988U1 phone. SIM card not recognized

I live in Canada. I purchased an S20 Ultra off a seller on Canadian best buy (open box). I assumed it'd be a Canadian variant, but it was an unlocked US version (U1 firmware). OK whatever, but it meant my Samsung Pay doesn't work, along with a few other calling features.
I downloaded the patched Odin, downloaded the G988W firmware (with XAC CSC) with Frija, added the appropriate files to Odin (used Home CSC), and flashed it. The flashing itself went fine, but when I went to re-insert my SIM...nothing. It didn't even error out and say "No SIM Detected", I just had no coverage, and in SIM manager, both slots were empty.
Freaked out, and eventually flashed back to G988U1/XAA and thank Christ it works now. But my question is...why?
I dug though this forum before doing it to try and anticipate any issues. Followed the instructions to the letter, nowhere said this would be an issue. Couldn't even find any relevant support questions for this issue on this model. Not sure if it's a new development, but I absolutely don't want to risk messing my phone up further if I reattempt.
Bonus question: My CSC info is: XAA/XAA,XAA/SPR. Does that mean that it was originally a Sprint model phone, someone's flashed the firmware to an unbranded version, then sold it off as New (Open Box)?
You can't just flash a firmware from a different phone. The hardware is different, so the way to communicate with it is different. You're lucky it even booted, I wouldn't have expected that even. You're simply stuck with the original firmware and CSC list. Or, maybe you could try with custom ROMS but I wouldn't be so sure about it. Either way, you'll have to use a ROM/firmware that is built for your phone (G988U1).

Huh I thought the actual hardware between U1 and W was the same? They're both Snapdragons. Besides I've seen other posts of people doing the same (tbh, they were going from W to U1, but still)

Oh but you CAN.
U, U1, and W have all been cross-flashable ever since Samsung first introduced universal hardware, starting with the S8

Probably. Very common for online sellers to do.
The key probably lies in what the CSC shows as after flashing W firmware. If it stays as XAA, changing the CSC manually to a Canadian one could possibly make it work

I thought so too, lol
Any thoughts on why my flash caused the SIM issue? Did I maybe just install the wrong version? I don't think I did, I used Frija
Some further research led me to the subject of accidentally mucking up the modem firmware which I might have done

I Just did exactly the same and got a tmobile variant but want the W preferably the samsung factory rom not a carrier one. Which guide did you follow? I found this for the 21 Ultra and expect the steps to be similar https://forum.xda-developers.com/t/...-samsung-unlocked-bloatfree-firmware.4224423/
What calling features don't work in Canada? I have a W variant, live in Canada, and want an U1 to get esim working. I am also looking for a guide to follow to flash my phone.

Samsung Pay doesn't work - that's a big one for me, it's a pain in the **** losing that. Will only accept US ZIP codes when setting up.
Caller ID doesn't work
That extra info you get when texting (like seen/read stuff) doesn't work in the native Samsung text app, you have to use google messages (yeah, no)
I'm sure there's other stuff but those are the main ones
