unbrand verizon phone

its possible to do it like on the s7.. where you can flash the us unlocked firmware (g935u) on a branded phone like g935V

I'm hoping so. I do not have the s8+, but I've read all US models share the same model #, with a U at the end.

yesterday i try to flash the generic US fimrware, the 4 files flashed succsesfully., but when the device reboots send me to recovery, make wipes and reboot and stills verizon. not sure what i do wrong. hopping a someone have success and share it with us. i use odin 3.12.3 and download the fimrware from the samfirm exe you can find here.. using the phone model sm-g955u using regio csc USC

I hope so. Maybe we'll just have to wait until someone uploads the stock version from a Samsung direct version, or find a way to avoid the Verizon boat and blocks. I miss the built in caller ID.

Updating here, it seems that Best Buy is selling the unlocked Snapdragon version in stores now. Does anyone know how to extract the firmware from the phone? If someone could link a tutorial I could try going into a store and extracting it for us.
Nevermind I just saw it was a pre-order, expected at the end of this month.

Guys, download the Canadian XAC and Verizon VZW firmware from updato site. Follow these steps to have an unbranded Verizon S8+. Make sure you use the Prince version of Odin to flash.
I have Verizon S8+ with no bloat, working scloud and called id.
1) New vzw S8, didn't set it up, just skipped all steps.
2) Activated dev mode and used "adb reboot bootloader" to go into download mode
3) Flashed XAC firmware with non HOME_CSC
4) Set up phone normally; however, for security I only enabled pin + require pin on reboot. Enabled dev options again
5) Used adb reboot bootloader to get into download mode and flashed HOME_CSC only
6) Restarted and used *#2263# to get into the band selection menu, tapped enable all bands and hit apply
7) adb reboot bootloader and flashed VZW firmware, but used HOME_CSC for the csc file.
8) It takes about 3-4 minutes to reboot after entering pin for decryption
That resulted in the S8 being XAA/VZW/VZW with everything working properly

I read this but saw later in the thread he said he couldn't get signal working or edit his APN settings.
I took a leap of faith and tried it. Everything looks and feels like the stock unlocked version. Texts, calls and LTE are working just fine when I flashed as described. Thanks!

Glad it works for you. I've had no issues at all with it. FYI, if you ever want to get back to stock VZW, just factory reset in settings and everything will revert to stock Verizon.

At step 7 when you flash the Verizon firmware, are you flashing AP, BL, CP from the Verizon download firmware and then the Home_CSC from the XAC firmware?

I did and all seems to be working great minus one side effect. Video calling in advanced calling is greyed out. I very rarely use this but is worth pointing out. I haven't yet tried calling vzw customer service to see if it can be enabled.
But do have scloud support, called id and places tab on dialer. Also note have the auto reboot function in settings.

Yes, that's correct. The U version of the s7 edge did not have video calling either. I use Facebook messenger or duos anyway because I don't know which contacts use Verizon.

I think it's also worth noting that I had the advanced display color control before I flashed the VZW firmware, but was back to the non-advanced control after. I'm sure this is because the vzw firmware is an early release. Maybe once updato site gets a newer firmware it can be flashed and see if we can get the latest vzw fixes.

Help with flashing U1 firmware to my Verizon G960U

.

DetectiveTaco said:
I have a Verizon locked Galaxy S9 (G960U) and I want to remove all the carrier branding and crap since. With the US Snapdragon Samsung devices having the bootloader locked and preventing the ability to root or flash custom ROMs this is the only way I can get rid of the carrier branding garbage. Though there is so many firmwares and different versions of the G960U1 firmware that I don't know what to get. Or which version of Odin I need or what to do to flash using Odin. If anyone is willing to help and walk me through this process that would be amazing because there is no good detailed step by step guides or videos on YouTube on how to do it. Or they aren't recent.

get the patched Odin here
and the latest U1 firmware here
put the 4 files from the firmware in their respective spots, using CSC to factory reset the phone and HOME_CSC to flash the firmware without resetting.
let me know if youre not familiar with Odin enough to understand what im getting at

DetectiveTaco said:
One last question, did your CSC change when you flashed the U1? My CSC before flashing was VZW/VZW/VZW and it's still VZW/VZW/VZW. In the phone info app it says my firmwares CSC code is XAA which is what it should be since I flashed the XAA G960U1. But then it says the active CSC code is VZW. Does this mean I will not receive the unlocked OTA updates from Samsung directly like I thought I would, and instead I will still receive the Verizon OTA updates instead. http://imgur.com/a/KgooKUR
Click to expand...
Click to collapse
it should still get updates for the OTA version. What happened is when you put the vzw card in, the firmware chose VZW since that was one of the available CSCs in the package. No worries man

.

.

DetectiveTaco said:
Or is it like because the CSC is Country/Region/Operator and VZW was a part of the multi CSC package but the firmware uses the XAA CSC code it will pull the updates from the XAA provider in this case that being Samsung.
I will probably wait until the next update for XAA devices is pushed and see if I receive it. And I'll either report back here or PM you if I receive the OTA for the next XAA G960U1 update

thats what i was driver after. the version of firmware you flashed contains several CSCs and the vzw one is what the phone latched on to. If you popped another sim in there thats within that csc list, itll probably do similar stuff with that
yeah, feel free to hit me up. if you pm me on here, i might not answer super fast, but ill eventually get to it lol

DetectiveTaco said:
Yep sure thing. Hopefully the October patch will get pushed soon and ill found out.
Click to expand...
Click to collapse
oh, forgot to address one of your previous questions. You can flash those files all you want, the nice part about them is that if youre flashing a new version on top of the old one, just flash the CSC_HOME and it will keep your phone exactly how it was but still apply the update. Its pretty sweet

.

DetectiveTaco said:
Yeah I flashed the regular CSC going from G960U to G960U1 because how it was a bigger transition and I didn't want to leave traces of Verizon crap.

very good. thats a perfect example of when to use the CSC vs the HOME_CSC

Samsung Note10+ Not updating at all

Hi All,
My apps are updating fine and i see that android 10 has been out for a few months now yet my Note10+ SM-N975U is not updating at all. it seems my security patches are still stuck on august 2019 and every time i try to OTA update, it says my phone us up to date. Is there anyway to bypass this. I see everyone saying to use Odin to update my phone but i am not familiar with the program and where/how to source the note 10 update
Id greatly appreciate the help as its affecting many of my apps

+1 for me. Ive spent almost 2 years and 3 phones trying to get an answer to this. My note 8 had this problem, then my note 10+, then the replacement note 10+. At&t blames Samsung, then Samsung blames at&t, over and over and over. I even had a Samsung technician sit in on a 3 way call with an at&t technician for the better part of an hour. The last I heard was that at&t was petitioning samsung to fix something on their end because at&t shows that everything is up to date on my phone but its not. Im looking into Odin too because this is getting stupid.

At&t is horrible with OTA's. They work for some but for a lot of people it does not, and I am one of them. At&t has never been able to give me an answer as to why this happened on my Note 8..9..and 10+.
Odin is very easy. You dont have to use At&t firmware you can use any Snapdragon US firmware they are the same. Once its installed, it will provision to you sim. There are many threads that have the firmware needed or just us Frija to download the firmware. Once downloaded you need to extract the files. You will have BL..AP..CP..CSC...HOME_csc. You need to download the correct version of Odin to flash the firmware. Open Odin put device in download mode connect device. Once odin recognizes devices find where you extracted the firmware. In odin put BL in BL spot..AP in AP spot..CP in Cp spot. If you want to save data, put HOME_csc in CSC spot. If you want clean install put CSC in CSC spot as it will wipe device. Once you have everything where it should be click start and Odin will flash the firmware. Once complete Odin will say PASS at top left..boot time should take a few minutes. But remember if the firmware you flash has a higher bootloader you cant downgrade back to previous version.

So I can use a verizon csc and it will work on a att branded phone? Or is a generic one better?
Edit
Basically which one do you pick. I'm leaning towards a tmobile because it sounds like the included bloatware is smaller.

I have At&t device purchased at At&t. I have used USC..Tmobile..Verizon. The device will provision to your sim. If you dont want bloat just flash U1 firmware. But I think you will lose advanced features like wifi calling if you do. I cant remember if flashing a (U) csc with U1 firmware brings back advanced features. But prob just stick with 1 firmware until you have a understanding on how to do this...Good luck.

I actually went ahead and did this last night with the tmobile firmware and it was just as easy as you said. For whatever reason I didn't even get any bloatware. It booted up with the at&t logo and sound, and my software version says att/att/att. I put my sim card back in and there were no special notifications or anything, everything just worked. I wonder if Frija gave me the att firmware despite me putting in tmb? Either way, everything is up to day now. Thanks for the help!

Anytime my friend glad it all worked out[emoji106]

Hi I have the same problem. I flashed android 10 One UI 2.0 on my Exynos Note10+ SM-N975F last December via Odin and download the firmware from Samfrew(like Sammobile).(the firmware is the German version and I bought my phone from Egypt) Since then I didn't receive any security patch updates I only have the December 2019 one. Will it be safe if I download the latest firmware from Sammobile and flash it; the file in over 5GB , can this overwrite? I never tried to flash the same software two times. Is it safe?

As long as you are using the firmware that is for your device and your region you should be fine. Although this is Snapdragon thread I would think International flashing is same. You may want to double check in your device specific thread as I don't want to be the blame if there is something different with F version.

Also try turning off auto update date and time. Set date like 5days ahead. Then check for update. Sometimes this little trick works for OTA

SM-G965U Odin firmware update from android 9 to android 10

Been wanting to update my s9+ from android 9 to android 10 but I cannot do OTA since I keep getting "Unable to update the software. A network or server error occurred. Try again later" -- already tried clearing cache and changing dates.
Also tried the switch method but that just tells me my phone is up to date.
Looked around and seems like Odin was the only way to upgrade.
Just have quick question: Can I flash the firmware if I haven't unlocked my OEM?

you certainly can flash it. the only issue youll run into is flashing the U1 version on a non U1 phone (U1 is the factory unlocked FW version). You can even get around that with patched Odin. Anyways, your answer is a yes

the firmware mismatch alert in Odin will force a crash and not allow the flash to occur, patched Odin ignores the alert and just punches it through anyways. You can SEVERELY bork your phone with patched Odin, so be careful. Also, patched Odin is here and the best source of firmwares is sammobile.com/firmwares but use samfirm to download it as its literally 5x faster than directly DL'ing it.

Stock Firmware for Samsung Note 10+

I'm using Samsung Note 10+
Model number SCV45, a Japanese variant with a name tag "au" & has the Snapdragon processor, not Exynos.
I want to flash the stock Firmware again.
I have visited SamMobile website to download the firmware of Note 10+. But there are lots of model number available like -
SM-N975F
SM-N975U
SM-N975U1
SM-N975W
SM-N9760
SM-N976B
SM-N976N
SM-N976Q.... so on.
But i didn't found "SCV45" model number.
As far as I know, SM-N975U, SM-N975U1 is for USA region with Snapdragon variant & SM-N975W is for canda region, also with Snapdragon.
If I flash any of the firmware of USA or Canada variant on my Japanese variant device through Odin, is there will be a problem. I have no idea about that as I'm a new user of Samsung. I have always used OnePlus. So I don't have enough knowledge about Samsung firmware.
Please let me know about the fact.

Thanks a lot brother.
But actually, I want to try out US region firmware on my device. So I'm asking, is there any problem if I flashed
SM-N975U or SM-N975U1 firmware? What will happen if I do so?
I need a clear idea about that, because I don't have enough knowledge about Samsung firmware & also I don't want my device turn into a bricked device.
Hope, I will get a clear idea from this XDA forum about that.

maybe your device is rooted or there is a mixed firmware so coming back to original firmware is not without risk
can you post :
- device version:
on dialer : *#1234# or *#12580*369#

Here is the Device Version that you want
Actually today I tried to add a edu mail account on google and it's showing that "Can't create a working profile, here is what error message I got.
I have checked, I don't have root access. And I also running stock Firmware as I got OTA update from Samsung for One UI. So I don't know what is the actual problem. That's why I want to shift from current firmware to USA region firmware.
But I am in a doubt as I don't have enough knowledge about that.

you can't flash a N970U or U1 full firmware
maybe only the CSC part if it work but at your own risk

I believe you can try to flash some completely other version, but no one can be sure if it will work.
I would suggest to have a spare Japan OFW to reflash if anything goes wrong.
Your latest FW according to samfirm should be -> SCV45 -> Region KDI
Version: SCV45KDU1DVC3/SCV45QDI1DVC3/SCV45KDU1DVC3/SCV45KDU1DVC3

I know it's hard to find someone who has tried out what I asked for. I don't know whether it will work or not. But I just want to make sure that after flashing a different region firmware, it should not become a hard brick device.
If something goes wrong, at least I flash the SCV45, Japan variant firmware again & everything turns to a normal state as it is running now.
So should I proceed with SM-N975U, USA variant firmware? Will it gonna make my device hard brick? Can I come back to normal state by flashing SCV45 KDI firmware which is mentioned by you?

I would personally look for the model, which is the most similar to the japan one and just... pray while flashing

and also, dont forget to flash the "CSC" file, not the "home_CSC" to change the region. (the home_CSC doesn't change CSC and leaves your apps and other stuff intact. On the other hand, the CSC file wipes everything and changes the region.)

I am too much grateful to brother for your suggestions what I actually expected for.
I will follow all your instructions.
I will flash the "CSC" file only. Thanks for let me clear about this thing.
I have just a little confusion about what you have told above.
You suggest me not to flash bootloader. Can you please give me a clear idea how can I skip it or at what step, I should not flash the bootloader? I have just this confusion.

Well... You have to flash through ODIN.
So. In the ODIN you have several options on what to do (what to flash). When you download the FIRMWARE you will have to decompress it. there will be different files -> BL (Bootloader - BL), PDA (the firmware - AP), PHONE (modem and stuff - CP) and CSC (vendor or region specific info).
Firstly I would try to flash only AP + CP + CSC. Which means Firmware + Phone + CSC. Be sure to flash the same version of Android as you have. In that case it should... maybe... probably work the same. If you have bootloader from Android 11 and you try to flash Android 11 from another version, it should work theoretically....
But if you try to flash eg. Android 12 over Android 11 it won't work because the Android 12 uses different bootloader and you need to update it.
It would be most desired to flash the bootloader also. But my suggestion for you is to try flash different version without the bootloader (if it can be done). Because if you don't screw up the bootloader, you will be always able to boot to bootloader a flash back the original firmware.
I don't have the knowledge to tell you, that if you flash USA version of bootloader to the JAPAN version of bootloader that it will work. It probably should, but I believe, noone can answer that and it's just that you will have to try it.
I believe that the ODIN will tell you that you are trying to flash firmware from completely different device and if you are sure to do that.
So again:
1) download firmware from different location with the same android version
2) decompress the firmware
3) in the ODIN -> add only AP, CP, CSC (don't add the bootloader)
4) try to flash!
If it doesn't work, you can try even to flash the bootloader, but I'm a bit worried about that one....

I am highly grateful to you as you have explained the whole thing so clearly. Now I understand all the steps that I need to do. Thank you so much for clearing up the matter in so much detail. Now I can proceed.
I will try as per your suggestion. Let's see what happened.
Thanks again.

bootloader is in AP !

Then what should I do?

before flashing a part of firmware , i think it's better to know more about root
i'm not familiar with root and my lastest rooted device is a galaxy S6
why do you want to change the firmware ?

I have checked and I don't have any root access. I have told you why I actually want to change the firmware in some previous reply.
Here I am mentioning the whole problem again for your better knowledge.
Actually yesterday, I tried to add an edu mail account on google and it's showing that "Can't create a working profile", here is what error message I got.
I am running on stock official Firmware, I confirmed that as I got OTA update from Samsung for One UI. So I'm not using any custom OS.
But I don't know why it's showing that I am using a custom OS . That's why I want to shift from current firmware to USA region firmware to check whether the Japanese region firmware has issue or not.
But I am in a doubt as I don't have enough knowledge about switching from one region to another region firmware in Samsung devices.
I hope you can understand, though my English is not great
