Hello, I have the Galaxy S10 5G on Verizon, SM-G977U. I'm currently running the latest Android 10 update: G977UVRS3YSL6. I moved away from Verizon and switched to T-Mobile, however I wanted to remove the carrier bloat, and potentially switch the CSC to XAA or TMO from VZW. I was able to remove all Verizon bloat by doing the following:
YOU MUST REMOVE YOUR GOOGLE ACCOUNT PRIOR TO THIS. YOU WILL TRIGGER GOOGLE FRP LOCK.
Opened the dialer and used the code *#272*IMEI-NUMBER#.
Saw two CSC codes, VZW - the active one, and a second one, GCF.
Switched to GCF, and the phone did a factory reset.
After the factory reset underneath Service provider SW ver. it listed GCF/GCF/VZW and all verizon carrier bloatware did not get installed.
So while that's nice to have removed the Verizon bloat, I wonder if I can take it one step further and switch the CSC to XAA or TMO. I'm lead to believe that I can change the CSC to one of those, because it appears since switching to GCF, also underneath Service provider SW ver. it lists the following: SAOMC_SM-G975U_OYN_GCF_PP_0009. This appears to be a Galaxy S10+ CSC code, would it then be possible to flash the SM-G975U or SM-G975U1 CSC codes onto the SM-G977U? And thus be able to change to XAA or TMO or any of the options of a unlocked firmware?
On doing your change from VZW to GCF, does that prevent OTA updates from Verizon?

I believe if you have VZW as your current carrier, as long as you still get service, you will continue to get OTA updates.
Thanks.

Also don't forget to remove your Google account from phone prior to this. It will reset and erase everything. You will trigger Google frp lock.

Hey, bud!
So I did the exact same process as OP in a Verizon s10 5G.
However, I made the mistake of not removing my Google account, when I start the phone I go through the process of select lenguage, blah blah, then choose wifi and click next it just loads and says I need to start the setup process again because I didn't log in to my Google account. However I'm not even able to type in anything, it just skips the whole typing process. I'm just stuck at setting up the phone... Can't do anything else. Do you know anything about this or how I can fix it? TIA
You'll have to Odin flash AT&T Firmware then back to Verizon I believe, or flash CSC. I don't quite remember.
I'm pretty certain it was flashing AT&T and then back to Verizon though, the reason for flashing the AT&T firmware is to force the CSC code to change, as VZW and GCF don't exist on the AT&T firmware.
Don't fret though, I did the same thing as you on my first attempt

The way i got around this issue was to flash back to android 9. Once there you can log into your google account. Then remove your account and flash android 10. Now you can log in to android 10.

When you changed to GCF, did this remove the Verizon boot logo?
How to remove that?
Hi there!
First of all, thank you for the explanation! Everything went perfectly and no bricking occured.
Nevertheless, there's something that doesn't seem to be working. Since the wiping, the Setup Wizard can't finish the process. It keeps crashing and on a loop. There's a notification I can't even remove.
Did you encounter this problem too?
I'm attaching screenshots of the error message I'm getting.
By the way, do you know if this process is reversible if your current carrier is not American? If yes, how could I do so?
Thanks a lot!
I also have the same situation. have you solved this problem yet. Can you show me

For anyone who might still be wanting to do this, if you run the command you will be prompted with 3 choices. Network and Sales change, just network, and dev.
If you want to remove all Verizon bloat, you have to select network and sales change, however you will run into the issue above. Where the set up wizard will fail and crash but you can still add google/samsung/etc accounts and full set up the phone. The notification doesn't go away and if you try and run it again, it will just keep crashing.
The 2nd choice that won't cause that issue is just the network change. Pretty much will enable all bands/sets phone into global mode for network settings. BUT it keeps the Verizon bloat. (personally went from 1 bar to 4 in my house with tmobile sim in Verizon software phone)
I personally settled with the 2nd and just disabled what I could. So I didn't have any constant notifications and wasn't limited to Verizon's bands after getting the device unlocked.
Just something to keep in mind for those who are planning on or have switched to ATT software, you only have the DEV option.
Forewarning: I cannot guarantee this will work for everyone or that your data will not be wiped. Backup, backup, backup! This resulted in NO WIPE for me. All data was intact.
I just spent a long time trying to figure out why I cannot get the October updates on my Unlocked S20FE that is currently on T-Mobile. No matter what I did, I couldn't get it to give me an update option. I heard swapping SIMs with a non-TMo provider will do it, but I didn't have access to one.
This led me to learning about Samsung's CSC system. CSC is "Consumer Software Configuration" or "Country Specific Codes". These codes are locked in to the phone until a new SIM on a different carrier is inserted. I tried many network reset options with no luck. You have to force a reset of the CSC.
First, the initial CSC for my USA unlocked S20 FE 5G is XAA, which just tells the phone it's an Unlocked US model. You can see your CSC codes under Settings > About Phone > Software Information > Service provider SW ver. Look at the third line and see 3 codes like such "XXX/XXX/XXX". My understanding is Samsung saves a history of CSC codes: 1) The current 2) the previous and 3) the original. It can move back and forth between the first 2, but the will never resort back to the 3rd (original CSC) even if you remove the SIM. Before, I saw TMB/TMB/XAA. TMB is the T-Mobile CSC, and XAA is my original. So I needed to somehow overwrite the TMB codes to XAA.
How to:
1. Remove SIM and keep it out until the end.
2. Go to Settings > About Phone. Long press the 15-digit number next to IMEI to Copy it, or write it down.
3. Open Samsung Phone app, type *#272*(IMEI NUMBER)# <Paste your IMEI without the (), and Dial. You won't be able to dial this with a SIM in.
4. You will see a list of codes in a "preconfig" window with your 2 codes at the top. For Unlocked XAA models like myself, select XAA, (if you have a different original CSC, then use it). There are sites with lists of available CSC codes if you wanted to do different carriers/regions.
5. Click Install, and then select Sales & Network Code Change, (Network change only changes the 2nd CSC, you must select Sales & Network to change both 1st and 2nd CSCs), click Ok. and your phone will reboot. Once up, go back to Software Information, check the CSC codes are set to XAA/XAA/XAA, then you should be able to check for your software update.
6. Update Software, reboot, then insert SIM, and reboot again and you will be up to date and back on your network.
Essentially, you're just setting the phone as if no SIM card was ever inserted. Had you performed an update on a brand new phone over wi-fi before ever inserting your SIM, you would have the update the exact same way. After I got the update over Wi-Fi and my phone reset, I reinserted my SIM and my CSC codes are set back to TMB/TMB/XAA with the baseband version of G781U1UEU1ATJ5 and the October 1, 2020 Security Patch. Should this happen again where T-Mobile's updates are lacking behind, a simple CSC reset would do the trick again.
Good luck. Let me know how it works for you. Again, I'm not responsible for you messing anything up or losing data, but it worked perfectly for me. This could be used to change regions and carriers on your phone as well, not just for updates.
EDIT: I haven't been able to get back into the "preconfig" CSC change screen anymore. I've read that others have only been after to get back into the preconfig change screen after a factory reset. So it sounds like you can only modify the CSC once between factory resets.
EDIT 2: Of course, the day after I do this, T-Mobile finally pushes the update. I'll leave this information up for future usage.
EDIT 3 (07 Dec 20): Thanks to info from dopeyone2011, the dial code *#*#27262826#*# works to change CSC update multiple times after the original one. As of 07 Dec, I was still on the 01 Oct security patch on T-Mobile. December's isn't available, but I was able to get the 01 Nov patch. Hopefully T-MO gets their act together so this doesn't have to happen monthly.
Did this get you the ATJ5 firmware update with all of the supposed touchscreen fixes?
EDIT: Sorry, I see you mentioned that you now have ATJ5. Thanks! Doing this NOW.
EDIT 2: WORKED GREAT! Thanks for this great tutorial!!
Wondering if this would work on a Tmobile Locked phone
Sooo, after all this work, T-Mobile just released their update. FML! :laugh: I'll leave this information up for future usage, though.

Seriously? It must have been within the last hour or so because it wasn't available just prior to me using your instructions to update this morning.
You are a champion, thanks for this! I've been trying to figure out how to achieve exactly this. I still had not received the TMobile update as of 11:30am Central today. Did this and received the update immediately. Ran some of tests using Touch Screen Test and much better results (still not perfect). Will now try some gaming to see if it has fixed the intermittent unresponsiveness.

I misspoke. T-Mobile locked phones got the update, but apparently Unlocked phones on T-Mobile have not yet.
So, I'm learning more about this system. (I've rooted and modded phones long ago, but gave it up on newer modern phones, so know my way around Android systems fairly well, just not Samsung). I now want to know WHY the 272IMEI dialing "preconfig" doesn't work anymore. Even though I don't need to, I'm very curious if I can figure out a wipe-free/root-free fix.
Dialing the 272IMEI number opens an .apk called Preconfig, which is a sub app of CIDManager. When I try to open preconfig using Activity Launcher, I get a long error that says Permission Denial... and "requires com.sec.permission.preconfig". I opened up a file manager and went to the root folder, found the CIDManager xml file, and looked at its text, it references the preconfig.apk and its permissions, but I've searched for the preconfig apk and it's just not on the phone anymore, or completely hidden. It appears that when you do this CSC change through preconfig, it removes the preconfig apk as part of the process. Not sure why. I'm going to continue investigating how to get preconfig apk back on the phone, or even if it's possible without root. I need someone with a bone-stock S20FE to see if I can copy their preconfig.apk files.
EDIT: I had someone who updated their U1 XAA Unlocked phone by the AT&T SIM trick, and he's locked out of 272IMEI and preconfig options. I'm beginning to think the AT5J firmware just locks out the preconfig app removing the option for CSC changes?
Finally got update today in usa on unlocked t-mobile. I guess we're going to be late which sucks
im only replying to this so that i can add nothing to this thread other than perhaps a smile. We all know we could use more of that nowadays.
EDIT 1: updated purpose of post
EDIT 2: Self realization of my true purpose on earth
(felt like i couldnt post in this thread without the requisite 2 edits)
joking aside, nice write-up man! keep up the good work!
Got the update for T-Mobile today. Touchscreen issues seem to be resolved now so that's nice.
So it looks like the last Unlocked update came out 20 Oct, but it took 2 weeks to get to everyone? That means the earlier October update took even longer.
Not sure what else we can do but continue to hound T-Mobile and Samsung to give us these patches. Unlocked phones should never be last.
Any way to restore preconfig.apk?

Hi, Thank you so much for this method! Is there a way to restore the preconfig.apk after following the above method? should I have created a backup of the preconfig.apk file before following the above steps and restored it after, would that have worked?

I've found a method that works post firmware flash on my SM-G781U1 AIO/AIO/XAA ATJ5. Using this method, I have been able to alter my CSC as many times as I'd like, with the SIM card still inserted even. Not that that does a lot of good as it reboots to adjust for the carrier Sim directly after. First you download Phone by Google app. Set it as your default dialer. Next, you download phone info+the one that says Samsung underneath with a star on each side. Go to phone info plus and run the secret codes plugin. If you scroll down you will find a code that says CIDmanager. There are several instances of codes that say CID manager. The one that works for me is *#*#27262826#*#*. Entered in the phone by Google app with no need to use the dial button. I have been able to bring up the preconfig menu and change my CSC multiple times at will with this method.

Yea, if you type this code "*#*#27262826#*#*" in the google app, then hit the "Don't change this carrier" option on the bottom, you can stay on XAA. I was just about to post about this since xaa and vzw both block the *272* code
Slightly off topic, but, theoretically, if I changed the CSC to a region that has OEM bootloader unlock, removed the sim, rebooted, and used a VPN to mask my IP as being from the aforementioned region, would I be able to unlock the bootloader and root without paying $100 and giving remote access to my machine to a random Chinese server?

Incredible! *#*#27262826#*# works for me!
This is great info! Used it a few days ago to update my USA unlocked version to ATK1 without having to wait for slow-ass T-Mobile to push it (I'm using a t-mobile sim). I'll use it again to immediately update to One UI 3.0 when it launches for the S20 FE at the end of this month.

You can see your CSC codes under Settings > About Phone > Software Information > Service provider SW ver. Look at the third line and see 3 codes like such "XXX/XXX/XXX". My understanding is Samsung saves a history of CSC codes: 1) The current 2) the previous and 3) the original. It can move back and forth between the first 2, but the will never resort back to the 3rd (original CSC) even if you remove the SIM. Before, I saw TMB/TMB/XAA. TMB is the T-Mobile CSC, and XAA is my original. So I needed to somehow overwrite the TMB codes to XAA.
How to:
1. Remove SIM and keep it out until the end.
2. Go to Settings > About Phone. Long press the 15-digit number next to IMEI to Copy it, or write it down.
3. Open Samsung Phone app, type *#272*(IMEI NUMBER)# <Paste your IMEI without the (), and Dial. You won't be able to dial this with a SIM in.
4. You will see a list of codes in a "preconfig" window with your 2 codes at the top. For Unlocked XAA models like myself, select XAA, (if you have a different original CSC, then use it). There are sites with lists of available CSC codes if you wanted to do different carriers/regions.
5. Click Install, and then select Sales & Network Code Change, (Network change only changes the 2nd CSC, you must select Sales & Network to change both 1st and 2nd CSCs), click Ok. and your phone will reboot. Once up, go back to Software Information, check the CSC codes are set to XAA/XAA/XAA, then you should be able to check for your software update.
6. Update Software, reboot, then insert SIM, and reboot again and you will be up to date and back on your network.
Essentially, you're just setting the phone as if no SIM card was ever inserted. Had you performed an update on a brand new phone over wi-fi before ever inserting your SIM, you would have the update the exact same way. After I got the update over Wi-Fi and my phone reset, I reinserted my SIM and my CSC codes are set back to TMB/TMB/XAA with the baseband version of G781U1UEU1ATJ5 and the October 1, 2020 Security Patch. Should this happen again where T-Mobile's updates are lacking behind, a simple CSC reset would do the trick again.
Good luck. Let me know how it works for you. Again, I'm not responsible for you messing anything up or losing data, but it worked perfectly for me. This could be used to change regions and carriers on your phone as well, not just for updates.
EDIT: I haven't been able to get back into the "preconfig" CSC change screen anymore. I've read that others have only been after to get back into the preconfig change screen after a factory reset. So it sounds like you can only modify the CSC once between factory resets.
EDIT 2: Of course, the day after I do this, T-Mobile finally pushes the update. I'll leave this information up for future usage.
EDIT 3 (07 Dec 20): Thanks to info from dopeyone2011, the dial code *#*#27262826#*# works to change CSC update multiple times after the original one. As of 07 Dec, I was still on the 01 Oct security patch on T-Mobile. December's isn't available, but I was able to get the 01 Nov patch. Hopefully T-MO gets their act together so this doesn't have to happen monthly.

Question! I have an unlocked model (XAA) right now that I've been using on T-Mobile. Both ATT and now just yesterday Verizon has pushed the ONE UI 3.0 update. I've tried using the CSC change to go back to XAA to try and get the update but it's not there yet. Would it be possible to change to VZW instead of XAA using the above method to get the update from Verizon and then putting my T-Mobile sim back in after update to switch it back to TMB? Would getting the Verizon version of the ONE UI 3.0 update mess anything up on my unlocked device? I believe all carriers push the exact same version don't they?
Any confirmation of performing this procedure being able to wipe your device? Because I have an S20FE as well, but locked on TMobile
I'm updating this post to state that this method no longer works. It's been patched by Samsung. I used to use it all the time, but when you dial the number now, nothing happens. It used to bring up the CSC change menu.
Hi, i have a Pixel 4XL
baseband version g8150-00123-220402-B-8399852
i think its american , but i have installed the australian firmware on it , after a factory reset , and install a custom rom
this verizon software keeps reinstalling... can anyone clear up if this is spyware hidden ( i got the phone from a dodgy supplier online)
i want to remove it , yet it keeps reinstalling after multiple wipes.. i have erased slot a and b , reflashed recovery , reflashed firmware.
i intially thought it was reinstalling as it was linked to the baseband but from what i understand installing the Australian firmware should remove this system app ..
can anyone tell me how i can completely wipe this phone so this is removed. Do i need to edit the kernal to change the baseband someone at the phone shop suggested editing the Build Prop is this correct ? and if so how does one go about this.

I believe it's "normal" to have My Verizon Services, AppDirectedSMS and com.verizon.llkagent on your phone, although they should be disabled if not using Verizon (I have them on my Pixel 6 Pro but they are disabled). These 3 came with the phone out of the box and aren't spyware, but there in case you have a Verizon model or on the Verizon network, I believe.
If you really wanted to uninstall them you could root and try uninstalling them, but just disabling them should suffice.

i am in australia. using a american verison pixel, i was able to unlock the bootloader on the locked verizon version, and flashed australian firmware. but the verizon software wont remove unless i manually do it.
Does anyone know how to stop sprint / Verizon system applications from reinstalling, I can remove them with root but when I restart that creates a bootloop.. It is a american pixel. But I'm in Australia, I have tried flashing Australian firmware yet the problem persists, surely someone on here has the knowledge of how to do this, I was told on stack that it has to do with carrier - ID / device ID.
Hmm, have you tried moving to the USA, signing up with Verizon as a service provider, and then cancelling and moving back to Australia?
Jokes aside, you could try disabling or uninstalling it via ADB? Let me know how you go.
