Hello.
(backstory, boring) I have an SM-955F from Claro that I've been trying to unlock completely from the carrier. I've had lots of trouble with them and am pending a case with FCC to get out of their claws. In the meantime, I've been trying (without success, hence my posts) to get it working 100% with T-Mobile. I've had T-Mobile for years under a friend's name and couldn't get a device -so I took one from Claro when Puerto Rico was hit with the Hurricane (T-Mobile had no signal for months).
(Little-lot- of info) So, I had the phone updated to Sammobile's PCT 8.0 firmware -G955FXXU1CRC7_G955FOWA1CRC2_PCT-. But it didn't have the OEM unlock. At one point I remember installing TWRP but something happened to the phone and it wouldn't boot up. So, my act of magic (*coughs*, XDA) I found a way to get it back to official firmware (I think at first it was a Germany's 8.0 firmware*can't find the file name*). Anyways, I want to get the phone to have Wi-Fi calling, VoLTE, etc from T-Mobile and, for what I've interpreted, that comes from the CSC files.
Now, I found a thread that uses TWRP+AROMA to get a list of CSC files on the phone and I can just install the one I want. (I don't know if there's an easier way directly from ODIN but I've not found that compatible TMB CSC file for my phone to get the features working, if any).
In any case I still want my phone rooted (I think I triggered Knox, but the phone updated through the Samsung Updater just fine after installing a PCT 7.0 firmware -G955FXXU1AQCC_G955FOWA1AQCC_PCT-. Clearly I'm out of my depth)
(to the point) The phone doesn't want to install my TWRP file. Says "custom binary(RECOVERY) blocked due to remaining installment balance". Obviously it's Claro's side blocking it, I think?. But I can't get them to unlock it (since it's still "theirs", until I get my case resolved or pay their stupid balance. Long story short, Claro's service is **** and I regret not waiting to get my credit approved my T-Mobile)
So, how do I go about it? I read that its RMM blocked. But my state says normal. The OEM unlock only appears on the 7.0 -G955FXXU1AQCC_G955FOWA1AQCC_PCT- firmware (even then it won't let me install TWRP through ODIN). I honestly don't know. I'll appreciate all the help I can get to reach my goal of getting 100% on T-Mobile's features (mainly VoLTE, if possible-the feature is greyed out so I assume it can be activated). Can't even change the radio band on the thing. I read something about using Nova Launcher and having the widgets activate it through "Enhanced LTE" (I think) but that option doesn't appear on the list. I'd also like to delete all remnants from Claro on the phone, bloatware, booting logo and such. Since it's a 955F, I assume one can make it as if international?
Also, please check my previous post, I just realized I forgot to detail something. I did hit that "your phone has been modified, restart to undo process" and I forgot. Maybe that's the root of it all?
Any questions, please do ask. I'd like to get this moving. For now I'll use my Nexus 6 (God I love that phone a lot)
Maybe there's some compensation on this, maybe, if I get it done.
I've included the picture of the error and the info on Download mode, links for files I refer to also at the bottom.

Bump.
I have the same problem "custom binary (RECOVERY) blocked due to remaining installment balance", when trying to install TWRP, in my case I want to install Custom Rom and I could not, I have not found any solution to this problem, I do not have OEM on 8.0, and the RMM status is normal, I could unlock unlock SIM thanks to a friend with Z3X tool, do not charge for it but thankfully I made a donation for the hard work and also that the Z3X is not cheap at all, if you need to talk to him, you inform me to give you his contact.
SM-G955F Claro Puerto Rico.
I have the T-Mobile version A71 5g, model # SM-A716U. I can't stand the T-Mobile branding, especially the jingle on startup.I am trying to flash the generic firmware XAS-A716USQU1ATFB-20200713085932 with odin and it fails every time with a message on the phone.
Odin on the computer does not show any error. Once that process is complete the phone reboots to the bootloader and shows an error message: failed the resizing-data
Is there any way to do this without wiping the phone? I read some things that say you have to log out of google and samsung accounts, would that really make this process fail?

I doubt Odin cares what accounts you do or don't use. Shouldn't have any effect.
I'm not a fan of the T-Mo branding either. The all-pink screen splash is obnoxious.
Sounds like the problem is the internal memory partitions are slightly different between the generic image and the T-Mo image and it doesn't lime that.
So you think for this I will need to factory reset. Do I just select re-partition in odin and then select CSC file instead of HOME_CSC file?
And is there any risk of tripping the efuse or setting the warranty void status to 1?
In the meantime I tried the *#272*IMEI# and this is just such a mess. When I set it to XAS the phone thinks it is Sprint phone and tries and fails to activate. When I set it to XAA then that doesn't happen but it refuses to make VoLTE call and calls over CDMA do not connect for some reason. I am using Verizon SIM card BTW. Also in XAA T-Mobile 5G does not work.
But now it is stuck on XAA *#272*IMEI# does not bring up the menu!

Where are you finding generic (unlocked) firmware?
I've looked on SamMobile & couldn't find anything for the SM-A716U.
As best I can tell, there is no unlocked version of this firmware nor does Samsung even offer an unlocked version of the phone itself.
I don't know, this is all very confusing. Some random websites say XAS is generic firmware, other random site say XAS is Sprint. And then they show a BST firmware too but nobody tries to guess what carrier that is for.
In any case if I used the *#272*IMEI# menu to switch it to XAA and now Verizon VoLTE doesn't work and T-Mobile 5G doesn't work what can I do to revert back to stock since the *#272*IMEI# menu will no longer show up?

Have you tried using Samsung's Smart Switch desktop tool to restore your phone back to stock?
https://www.samsung.com/us/support/owners/app/smart-switch/
Smart switch doesn't give me any option. The old version says this phone is not supported for recovery.
And now I can't even get the phone back to download mode
I am also looking for a way to update my A71 5g to Android 11 and OneUI 3.
I have the model number SM-A716U, the AT&T variant that is network unlocked and on Metro-by-Tmobile.
I have been looking for a way to update the phone but I only found the firmware for model SM-A716U1 which is the unlocked variant.
I don't want to take the chance of bricking the phone.
But the firmware is from AT&T but the model number is different.
There is an update for the right model number but it can't be downloaded anywhere.
Smart Switch also doesn't recognize that there is an update.
I guess I am just stuck with Android 10 and OneUI 2.5
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.

Thank you
I'm not too familiar with this community or android rooting in general but I still want to see what I can do. I want to know more than just the state of rooting, is there a way to unlock the boot loader, is there a way I can remove some (if not all) of the preinstalled spyware and replace it, what can I do to better protect my privacy? I figured I'd check out this community as this is where I was lead when I wanted to root my old Kindle Fire and since this community doesn't just direct to sketchy proprietary tools like kingroot (or maybe you all do, IDK I haven't been here very long). If I could remove alot of the spyware/bloatware I wouldn't be as concerned with rooting or flashing a custom rom as those would be just nice to have if I could get the preinstalled OS to be more privacy focused. I know I can't really escape google since they're embedded right into android but what can I do about Samsung? If I can't do anything on the device I would still like to know if there is a list of domains I could block using a pi-hole. Thanks if anyone has any info, also my phone is from the T-Mobile distribution, I feel like that probably matters.

The reason I specified replace is that I already tried this and it broke nearly everything, for example:
despite the fact I have a different keyboard, all keyboards broke, I couldn't get the keyboard to show up.
The entire OS became very unstable

(Sentence removed for stopping confusion)
Without TWRP, replacing the OS will be impossible.
Maybe downgrade to a older phone that has greater custom ROM support.

Not fully bricked, but it can be semibricked, i.e. not completely working as a mobile phone.
Xiaomi boot loops when certain apps are disabled, which is nasty and needs a factory reset to 'unbrick' it. Not sure about Samsung.

I think you removed things that shouldn't have been, or you didn't have the alternate app (e.g. keyboard) set as default. If you look at my post history, you can find the debloat list that I posted, which is 100% safe to remove without affecting the usage in any way whatsoever.
More aggressive debloating is possible, sure, but you risk breaking some things. You can always reinstall whatever you removed with "pm install-existing" as long as you used -k when you removed.

No , unless your rooted. whatever you debloat while unrooted can be fixed doing Factory Reset

It can be rooted with Magisk V23.0 but you need to unlock the bootloader first.
The bootloader is unlockable up to V3 but this is a paid service.
To get rid of this bloatware i would suggest you flash an unlocked firmware.
You can always flash a SM-A326U1 XXA ROM (https://www.sammobile.com/samsung/g...M-A326U1/XAA/download/A326U1UEU3AUF2/1558540/) by using a patched version of ODIN 3.13.1 or later. I was able to do this using ODIN 3.1.4 3B
I now have a TMO SM-A326U without any preinstalled TMO bloat. The XAA rom did not install any TMO software that I noticed at a high level and seems like a plan stock A32 5G.
Just make sure the SM-A326U1 baseband is the same version or high than the installed SM-A326U. The base band number will be the 5th to last number in on the About page under baseband.
Edit * I was checking my computer and noticed I had the SM-A326U1 roms for XAA and TMK. I can’t recall if XAA gave me an issue during the flash and I needed to use TMK, but the end result is, my A32 5G has no TMO bloatware installed.
I hope this helps someone.

The XAA and TMB are what are referrred to as CSC codes. Each carrier has their own:
ACG – Nextech/C Spire
ATT – AT&T
CCT – Comcast
LRA – Bluegrass Cellular
SPR – Sprint (CDMA)
TFN – Tracfone
TMB – T-Mobile
USC – US Cellular
VMU – Virgin Mobile USA
VZW – Verizon
XAA – USA (unbranded/unlocked/default)
XAS – USA (unbranded/unlocked)
ODIN is software used to flash firmware on to Samsung devices while in Download mode. I believe you need to use a patched version of ODIN to cross flash devices. Regular ODIN will most likely error out during the flashing process.
The SM-A326U is a carrier branded device which is why you will probably not find a ROM with a CSC code of XAA for these devies.
The SM-A326U1 I believe is the carrier unlocked version of the device. Regardless of the CSC you flash, don’t expect to get SM-A326U TMB flashed with the SM-A326U1 XAA firmware to enable OEM Unlock in the Developer Settings. It hasn’t appeared for me and I wouldn’t expect it to.
Please feel free to correct any of my assumptions above. I’m an iPhone guy using this phone with my ASUS router as a failover if my ISP goes down. Just tinkering with it from time to time.

ODIN is software used to flash firmware on to Samsung devices while in Download mode. I believe you need to use a patched version of ODIN to cross flash devices. Regular ODIN will most likely error out during the flashing process.

OEM unlock wont appear on the A326U.
The SM-A326U1 XAA & SM-A326U1 USC should be the debranded versions.
The XAA FW causes CSC to revert Whilst the USC doesnt.
Theres is NO XAS FW for this device.

So from my understanding:
There is a tool known as ODIN, this can be used to flash new roms
and from what I seem to know
I am most likely running a TMB version of the ROM as it was the default for my phone as it is a TMobile OEM version
So my question is now this:
How can I get a working version of ODIN
Where can I find a safe XAS rom to flash
I don't know if my phone is unlocked, if my phone is still locked to TMobile, could this mess with anything?
I am using SM-A326U not SM-A326U1, I assume the 1 version is unlocked?

ODIN is the software used to flash ROMS on to Samsung devices. You will want to look for ODIN 3.1.4 3B Patched On the forums or a search engine. The patched version of ODIN will allow you to flash ROMS with different CSC codes. It removes this restriction.
You are correct that the CSC code for your device is TMB. The CSC codes I listed above are some examples, not a complete list. There are no XAS CSC ROMs for this device that I am aware of, just as financeledger stated.
Your Samsung A32 5G is actually the SM-A326U model, but the SM-A326U1 roms also work on these phones, provided you use the patched ODIN. Only the SM-A326U1 has a XAA CSC rom which is bloat free. I have not tried the USC variant but I switched between the SM-A326U TMB and SM-326U1 XAA ROMs and back last night without any issues. You can find the ROMS at Sammobile.com SM-326U1 Roms it will be the third one in the list with the carrier name of Unknown https://www.sammobile.com/samsung/g...M-A326U1/XAA/download/A326U1UEU3AUF2/1558540/

Doing this will not unlock the phone in any way, shape, or form. All this does is provides you with an A32 5G without any carrier bloat. The boot loader still cannot be unlocked and the sim will remain locked until you’ve met T-Mobile’s conditions for unlocking.
I’d recommend on reading up on how to use ODIN properly as you can brick your device if it is not used correctly. Feel free to reply back if you still have questions. I’m not knowledgable enough to understand what financeledger meant when they said the CSC gets reset using the XAA vs USC rom. Hopefully they can provide some additional details regarding that.
Ok
to be sure I get it right:
Here is what I shal do:
1: Download https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/
2: Download the XAA ROM for the SM-A326U
3: Flash the ROM with ODIN
4: Hope I don't brick my phone
Is this right?
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!
