you donnt need to remove the .md5
you will need modded odin though.

You don't need to no, but it speeds up the process. I'm just posting firmware not making a hand holding tutorial. There's enough of those around

Thanks Joe I was tired of returning all the way back to the beginning and getting all those new updates on my unlocked S8

Yeah and on a Mac you do need to, or it freezes Odin completely

If I flash unbranded FW on a carrier specific device, loke tmo or att for example, would it sim unlock the phone?
If I flash tmo FW on an att s8 would it in turn allow me to use the att original device on tmo? I ask these questions because I feel like it would work for both my questions since flashing the FW flashes both boot, kernel and baseband/radio. The which is needed for signal. Just some theories but would love to know the answers.
Btw, I have a F model S8+ and was planning on buying some US branded devices so I was curious.

No, it will not unlock the phone (Note: Verizon phones are factory unlocked and remain that way after a firmware flash)
Yes, you can flash any carriers FW to a US S8 and use it with a different carrier.

So I understand, your saying if I flash att FW to a T-Mobile s8 I can use it on tmobile? If that is the case, to me that's an unlock of sorts tiny book lol. Just wanna make sure is all

You can flash att firmware and use it on TMobile but it will still be locked to TMobile. Just running att firmware.

Just realized the typo.....what I meant was, if I flash ATT on a TMO variant I can use ATT while locked to tmo? I'm very unfimiar with combination fw and always opted for the UK models for alot of reasons. Sorry for the confusion of my op question. I know on the s7 and edge if you flashed the US unlocked firmware it not only removed AOL bloat but it unlocked the device. So that is why I ask.

I had a TMobile S7 edge and flashing unlocked firmware never unlocked the device. That's handled by TMobile servers so...
Flashing unlocked firmware will give you just that. The smoother, bloat free firmware from another device but not the actual sim unlock.

I bought an unlocked device and wanted wifi calling so I flashed the g950usqs1aqf7 att firmware with Odin and it worked to enable wifi calling but I'm unable to get any ota updates and I hate the bloat. Is it possible to get WiFi calling with an unlocked firmware like this one? Also what is the difference between the U and U1 firmware variants?

There are plenty of threads on this, but I don't think anyone was ever successful. I flashed att Oreo to my u1 and got the options, but can't get my company to change my imei back.... My personal phone sim works fine. Quit at that point since it's an Ims registration error. You can try merging the wifi calling apks, but I'm pretty sure it's baked pretty deep in the os. The Verizon guys got some of it working. You can try their threads and see if any of it applies to us.

Thanks. Some threads made it sound possible but inconclusive. I'll just assume it doesn't work.
BTW, can you link to the att oreo fw? And what do u flash that with Odin or comsey?

The thread right below this one entitled Oreo ota has all the details and it needs to be side loaded through adb. Not Odin. But you will need to Odin the 950u base to get off u1

Ok thanks. I need to flash anyways because I'm having terrible battery issues and just debating whether to go to a newer version of 950u or back to U1 and losing WiFi calling. In your opinion is oreo beta worth it

So just to confirm, I have read everything, but I am just a bit confused. If I flashed the unlocked firmware via modified odin on a locked AT&T S8 it will remove a lot of the carrier bloat and give my my wifi hotspot back, but remove wifi calling. Similar to when I flashed the T-Mobile firmware on my AT&T S7 and got rid of a ton of the AT&T bloatware but was able to activate my wifi hotspot but lost wifi calling. I stay locked to AT&T which is fine that is not my purpose for flashing

The links don't work. Any chance you've still got the firmware? I've been overseas since october. I have an unlocked AT&T phone that I intend to keep using when I get back, so I want to keep it AT&T FW.

Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?

Unlocked Sprint Note 5 new firmware help

Ok, so my question ha a few points here. I have been flashing roms for many years but never really though of this until recently as I now have an unlocked phone.
1. As my Sprint Note 5 is unlocked, can I flash say the Unlocked Version of software to the phone taking away carrier branding? I manage a store from another carrier and I hate that when I boot my phone it shows Sprint. I know it will not trip knox as long as it is Official Stock software.
2. If I do flash said Unlocked version software replacing Sprint software, will it change my connection at all? I have seen that flashing ATT software on a Verizon device did manage to improve ATT tower connection however I wonder if this is maybe a placebo effect as opposed to actually changing the bands and connections the device makes.
If you guys could help me out that would be great. :good:
Cheers

There is no unbranded firmware for the Sprint model because well, it is a exclusive model so even if you flash XAS instead of SPR firmware some or all apps will still appear. The only way to get rid of everything Sprint is via custom ROM= tripped KNOX. The SM-N920P cannot run another firmware.

Sim Unlocked T-Mobile branded Galaxy s20+ ported to Verizon, flash Verizon firmware?

Hey there, I've tried to find this everywhere but no luck. S20+ purchased originally from T-Mobile. Ported to Verizon and would love to flash Verizon firmware but no luck so far with ODIN. Software is SM-G986U. Tried flashing Verizon firmware and Odin completed but still see T-Mobile startup screen and it wants to install T-Mobile apps. Tried flashing what I thought was carrier-agnostic software and then Verizon, both complete but still seems T-Mobile branded. Saw another forum post in a similar situation but with different phone/carriers stating that the phone software was locked to the carrier since it was branded to the carrier.
Can someone tell me if this is possible to do this? Not afraid of rooting my phone but haven't done that for years.
When I do a factory reset now and it offers me apps to download via checkboxes, one line reads "Verizon software" but then lists 3 T-Mobile softwares, so it's very slightly hybrid right now it seems.
Or is there another way to do this? Glad to post any info or screenshots. I would think people try to do this all the time but I can't find any useful info anywhere.
Is it true that no matter what I do, with a SIM-unlocked T-mobile branded phone ported to Verizon, that I won't get any OTA updates?
Thanks!

Wait I think I"m getting it from this thread using the patched ODIN ... will update on progress.

Since CSC change is not possible with latest UI 3.1 update what are options to change CSC

HI all,
With CSC change not possible using codes with latest UI 3.1 update what are options to change CSC?
For ex. I have SM-N986U unlocked Tmobile device but i changed CSC to ATT as im currently using ATT Prepaid and I'm on latest Apr update for ATT
How can i revert back to Tmobile CSC?
Do i need to flash Tmobile firmware using ODIN by first flashing to U1 firmware then Tmobile firmware or can i directly flash Tmobile latest firmware with Apr update using ODIN?
Will i be able to retain my app and data if I flash Tmobile firmware?
Any help will be appreciated.
Thanks

So you state csc change not possible then ask how to change it? lol.. and if it were as easy to just flash firmware in odin tgen that wouldve been the way to do it to begin with I would think lol

Update:
I was able to change CSC(ATT/ATT/TMB) to TMB/TMB/TMB but it was long and winded way. Just flashing firmware was not enough , need Tmobile sim to install carrier service and change CSC.
I followed the steps below:-
1) Did backup of my device using Smart Switch and removed my ATT sim.
2) Flashed latest T-Mobile firmware( N986USQU2DUC8 ) using instructions from post - https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/ . Also, downloaded the ODIN (patched version) and T-Mobile firmware from links in the post. Flashed HOME_CSC too.
3) After rebooting phone with new firmware , the boot up screen was still ATT and CSC was still ATT/ATT/TMB.
4)Shut down phone and inserted Tmobile SIM i had lying around.
5) On reboot, i was asked to install Tmobile carrier services and on restart , Tmobile logo came on boot up with CSC changed to TMB/TMB/TMB.
6) Now, i have esim enabled and SIM manager showing up too.

thats the normal process.. that firmware is same for each carrier.. firmware is multi csc which changes based on sim inserted.. shouldnt have to go through all of that really.. i think most ppl who have issues are trying to change csc without a active sim card or on carrier locked devices etc.
glad u figured it out tho!

Well, the confusion for most ppl who are new to Samsung and CSC, like me , is that we could change CSC with code earlier and now cannot. Didn't have these issues with pixel and iPhone.

Yes, I was able to change CSC to ATT from TMobile, enable all LTE/5G bands before One UI update.Not, sure what u find so funny .
Yes, I'm aware that there is no CSC concept in pixel or iPhone or any other other manufacturer that I'm aware nor they are crippled in terms of hardware capability from carrier software like Samsung. LTE/5G bands not being enabled , esim not being enabled etc.

actually other devices are crippled in some cased disabled entirely.. for example u cant get a tmb oneplus 9 pro 5g and use it on verizon to get 5g bcuz vzw 5g bands are disabled in tmb variant..
its really the carriers to be honest..
and I say LOL all the time even in normal convo so not actually laughing sometimes, just say it out of habit

I have phones such as Z Flip3 5G and other models that do not change CSC like older models when following the flash procedure starting with U1, but the phones never prompt a restart. I have noticed it seems to be with TMB or VZW units. Any suggestion on how to actually get the CSC to change properly or is this something they are doing with new phones to avoid being able to use them fully on other carriers?

Go to the page, download theirs Samkey app, buy few credits on Ebay and you can change the CSC as you wish in a minute, the phone will reboot without loosing your data, it's the easiest way as far as I know

Hi, I have yhe following issue and I need your thoughts please.
I have a Telus plan, canadian with US roaming option.
I am traveling in US alot. I have a Note 20 Ultra U1 from Samsung USA. When in US I can only register on Tmobile and I can get 5G icon too. Won't let me on ATT or Verizon.
With same sim card in Note20 Ultra "W" variant, canadian one, it wil register on all 3 major networks in US. No issues with the sim, I guess.
Also in Canada won't get 5G ever.
My provider said nothing to do with them, Samsung told me the same.
I reseted all network setings my APN is ok. VOLTE on. Only getting acces to Tmobile.
Any ideea how I can fix this ? Is it related to CSC ? Mine is XAA.

Question Can't change CSC from T-Mobile to Verizon with firmware S908USQU2AVDC

A question from a noob here. I have a T-Mobile S22 Ultra phone which is network unlocked. As I recently I switched from T-Mobile to Verizon, I'm missing some of the features that are Verizon specific, while not needing anything that is T-Mobile specific anymore. From what I understand, Samsung installs multi SCS firmware on most of the phones these days, which can be changed by a dialer code. That however did not work at all.
Another option I've come across is by flashing provider specific (in my case Verizon) firmware as long as firmware version is the same (S908USQU2AVDC). There are a number of articles on how to do it by using Odin. The issues is no matter what I do and what files I select (like by using CSC file instead of HOME_CSC with or without flashing USERDATA file as well) the result is the same. It shows success and reboots and then reports an error and does the full factory reset which ends up back on T-Mobile version.
The question I have if it's even possible? And if so what I'm doing wrong here. Unlocking a bootloader is not really an option for me...

In theory, flashing the correct firmware (VERIZON) should work. I would honestly first wipe the device, then flash (clean, not dirty) the Verizon firmware and setup accordingly. I had a similar case with a TMBILE unit (I had changed carriers) and I had managed to use XAA CSC and then when I reverted to TMOBILE SIM it would not "restart and install carrier updates". I had to basically switch the unit to U1 and then revert to U and it finally pulled all the TMO crap.

I may be mistaken since I haven't done this type stuff since S10, but I think you need to first reset the device and flash the unlocked version then when you put the verizon sim in it should provision it. Then you can flash the verizon package if you want the bloat apps. The features may be hit or miss. You may need to activate the features on the verizon website. Some features may never work as the carrier wont push them to IMEI not in their database of branded phones. There may be things you can do in hidden settings with "Activity Launcher" or other methods.
I'm here trying to figure out the same things for Tmobile and a factory Unlocked phone, before I buy.

Thanks a lot for your suggestions guys! I managed to do what I wanted. This is what I ended up doing, first flashed the unbranded U1 version on my phone and on the first boot Verizon sim was provisioned. Then I flashed Verizon firmware and it worked!
