Hey guys, I recently purchased a secondhand Z Fold 3 on a buy and sell website. I checked everything, IMEI and all (which was clean). I even got them to send me a video of the phone, and everything looked perfect. Even the flip case and the stylus was included. The deal was good but definitely not too good to be true.
Even after they sent it out to me, everything worked perfectly. Until I factory reset it a few minutes after getting it. After setting up the phone as normal, this is what I got after unlocking it.
Factory resetting from recover mode just takes me back here. I have no idea what to do, I was not careless, I made sure everything was ok, I'm so lost because I'm pretty good with tech but this is such a good scam and I'm just in shock. I just really cannot be losing money like this, especially when everything just seems to be getting harder everyday.
Is there anything I can do about it, even try and repair it if I can prove I bought it? Or even return it to Samsung and get some compensation? Any help is much appreciated, even if you dm if you can't say it here thanks everybody!
Images and them using it before sending it to me:

I'm located in the EU, I've been told I can flash a new ROM using just a PC without accessing the phone, is this possible?
Tough luck man.
- Firstly I would contact the seller for a refund, otherwise threatning that I will call the police.
- The fair thing to do would be to report it to the authorities but depending on where you live, this might be a good or bad ideea. (for example in Romania where I live, I once took a lost backpack to the police station and they were mad I gave them paperwork to do, literally asking me why I did I not take it or dump it in a ditch, which they probably did after I left)
- Otherwise I would try to flash a new rom on it or something depending on what is possible on the fold 3
good luck.
Seems like a money making scam, and I would factory flash the stock firmware for your device which should sort any issues out with it via odin. Wouldn't have thought it would take more than that to be honest ?
Once the IMIE has been flagged as stolen, no amount of flashing will get you back to a usable device because no carrier will activate it.
IMEI is clean, this looks KNOX locked to me.

Can't root without unlocking OEM unlocked, can I? Can't even get into the settings to do that, it won't even let me past the lock screen, even after factory reset from recovery mode.

Do you think I could flash stock firmware?
I tried flashing stock firmware but I had no idea which country to get, I only had the model number?
I tried Malaysia and EUA, both gave me fails on Odin. Now I think it’s EUB, will try that later when I’m home.
Maybe I’m using Odin wrong, I initially only inserted the BL file into Odin, and then all of them (BL, AP, CP and CSC). I didn’t know which CSC file to use, there’s 2 (CSC and CSC HOME I think?)
Tried this with both Malaysia and EUA, but both gave me OdinFAIL!(Auth)
What am I doing wrong? Any help would be much appreciated!

Just because it's clear on Public Databases does not mean it's not clear internally. I used to work for a cellular company (IT in Corporate, not a retail store) and those public databases are NOT refreshed too often and I would not say it's 100% not blacklisted.

Good point, but the quickest way to get BL is scam a carrier, this looks like another victim of trade and switch fraud. If this keeps happening you can bet (Samsung) will no longer offer the trade discount up front requiring paying the FULL PRICE at time of purchase and then refunding the discount once trade ins are received and verified.
Honestly, at this point, you are just pretty much stuck with a WiFi Tablet. If you cannot get resolution with the seller (which may not be worth the time and effort), then you will just have to chalk it up to Lessons Learned and move on.
I HATE HATE HATE to hear about people getting scammed, but there really isn't much that can be done.

I purchased a Galaxy S4 from Hong Kong - supposed to be model I9500, but I'm not so sure now.
Model: GT-19500
Device type: jflteatt
Product name: jflteuc
Knox Warranty bit not found
Original CSC code: TGY
Firmware CSC code: TMB
CSC country: Hong Kong (ISO: HK)
product code not active
PDA (and CSC) version: 19500XXUEMK2
Build code: ORG.19500XXUEMJ9
Android version 4.3
Baseband version: 19500XXUEMJ9
When I first started the phone I saw something from AT&T and when I checked settings/about device/ software update, it tries to open "AT&T Software update". When rooting the phone, while in Download Mode, I saw a small area with some written information and upon closely reading, it seems to say the product name is "SGH-i337".
So which product is this and does it make any difference? I've rooted the phone and everything seems to work. I can't get an OTA update, but I'm told no international model will get this. Should I just enjoy what I have or worry about something I'm missing?
Model seems to be incorrect. Should display SGH-i337 so somethings up there. But if all works good, I mean you should be okay. Of course there's a security risk, I'd return to complete stock if possible. I'm not sure if international gets the OTA or not though. The thing about phones from Hong Kong are that they are usually bootleg or fake, I don't mean to say all phones from Hong Kong are fake but check eBay and you'll quickly know what I mean.
An easy way to make certain of whether it's an i9500 or other variant would be to download "Device Monitor and Inspector" from the Play Store. If under Device->CPU it shows anything other than an Exynos CPU with 8 cores you most assuredly don't have an i9500. Then troubleshoot further from there.
I got my new unlocked G7 from ebay. I cannot get any over-the-air software update. I am using it in T-Mobile have no problem of using wi-fi calling, and HD calling.
Its software version is still G710ULM11g, Security patch level is Nov 1, 2018.
The Hardware info: Model number: LM-G710ULM, but the S/N displays nothing in it.
Any suggestion how to upgrade the software?
You need to upgrade manually.your phone most likely was sprint and the seller flashed with ulm software thats why you cannot update ota.
Use this procedure on this thead

Like the others have said, more than likely it was a Sprint phone (g710PM) flashed to a g710ULM. Go to IMEIPro or a similar IMEI checking site, enter your IMEI, and most likely it'll say g710PM. Literally just went thru this 2 days ago with a phone from Ebay, but I'm sending the phone back. Seller never disclosed it and I don't want to bother with some of the potential issues/shortcomings. Like they also said, you should be able to flash other roms on it, but be aware that future over the air updates are not going to happen, and others have had varying levels of success with getting Google Pay to work on the phone. This might be no big deal, but just putting it out there. Good luck dude.

I am in the same boat as yours, got it from ebay said new ULM, it even has sticker with ULM marked on it. But now I checked, it is g710PM. Too bad its too late to return. Next time, I won't buy phone unlock in ebay.

I checked it original is g710PM. Can I just directly flash the latest ULM firmware on it?
Hi,
I also bought one of the PM to ULM crossflashed phones from eBay.
I managed to flash newest ULM firmware, but still have the missing S/N issue and the phone is not passing Safetynet CTS check. So I can‘t install Netflix on the phone.
Has anybody a solution to fix theses Issues? Manual flashing instead of OTA is no problem, but Safetynet sucks.

I tried my IMEI its not in the DB 8(
I searched several different imei sites and didn't gain any success. The ulm I got was straight from a reputable distributor(sealed in box) as a carrier unlocked phone. I'm wanting to get back in to development after about 10 years hiatus.
I have however enabled "OEM unlock" in developer settings on the phone, so that's at least a good step forward.

Well---I went back to 20f because of WiFi calling. I had flashed the Canadian 30d (AWM)--worked very well everywhere but no WiFi calling. I live where there is little to no signal, so........
I would be interested if the EU rom has that......

did anyone ever figure out how these sellers have ‘new in box’ sealed box g7’s that have 710ULm barcode on the box and all
But are sprint g7 variants
Is this something lg did as a refurb type tactic themself and sent them out
Like sprint overstock and they dumped em off to resellers ....
I currently have the US s20Ultra unlocked model on ATT (don't foresee changing carriers). Currently I am missing features like VoLTE and VVM. What other features would I be missing if I stay on the unlocked firmware? Can I flash the ATT firmware to get those missing features? Can I flash back to unlock?
Thank you

I am not sure what I am looking for. Its currently on ATT/ATT.
Open your dialer, enter *#1234#, press the Dial Icon. You'll see CSC: G98??, the next 3 letters will be your device's CSC Code. Your Service Provider's CSC is "ATT" which is different than the CSC in your device. Whether or not you can change the CSC depends on your device's CSC. Device firmware is always configured for the specific, original CSC or Multi CSC's.
This post may be the best workaround.

Your device has Multiple CSC's which are included in OYM so you should be able to change your CSC to ATT, which is the CSC for AT&T.
Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press the Dial Icon, you should see a screen with the list of available CSC codes for your device. Select ATT and tap the Install option.
Be aware your firmware isn't AT&T, it's unbranded so even if you change the CSC, full call functionality may not be available. You can obtain AT&T's firmware at SamMobile.

Varcor, thank you so much for all the directions.
As it stands right now, it is already on ATT. Once I flash over to the ATT firmware, would I be able to flash back to an unbranded one in the future, for whatever reason? Additionally, do I have to stay on the ATT firmware to retain those features? Or could just having my phone communicate with ATT at least once with my "branded" phone and then flash back retain those features?

You're most welcome. Yes, flashing back to unbranded won't be a problem. I don't think you will be able to retain the features if you go back to the unbranded firmware, it's not configured to allow full call feature functionality. Also, after flashing to the AT&T firmware you may need to contact their CSR for external programing. Good luck!
S20+ AT&T
Hi Varcor,
I'm new in this firmware things. I'm from Singapore and has been using S20 Exynos, but due to the extreme heat, bad battery life,etc. I've decided to import S20+ Snapdragon from AT&T, according to the Service provider SW ver information, it's showing as SAOMC_SM-G986U-OYN_ATT_QQ_0023 (I believe this means the set are unlocked).
With that said, I noticed that the software is outdated and the security patch level is on February 1,2020. when I referring to the AT&T website, It's showing as the latest software is QP1A.190711.020.G986USQU1ATE6 (June update) and mine still on QP1A.190711.020..G986USQU1ATAW (February). My CSC is G986UOYN1ATAW.
My question now is, whenever I tried to hit the software update, it's keep telling me that my software is up to date. Is there's a reason why it's wont detect the update? If it's because I'm in Singapore not US, then there's no choice that I need to flash using the firmware from Sammobile. The problem is which one that I need to download as AT&T carrier is not listed there. There's only T-mobile, Sprint, Unknown, USA. Please help.

I would reach out to SamMobile and inquire why they're not listing the AT&T Firmware Update. You state your CSC is G986UOYN1ATAW. That CSC is also associated with T-Mobile. You're not using an AT&T SIM Card, correct? On a Multi-CSC Device when you insert a different SIM, the device should update to the correct Service Provider. If you're using a SIM from a Service Provider other than AT&T you probably won't receive AT&T Software Updates, which are distributed by Samsung, not AT&T via OTA.

I did try to reach them, but for some reason they are giving me some irrelevant answer. Something like "You probably don't get OTA-updates (otherwise you got them already from AT&T)". We are having a conversation breakdown there, I think they are not an english speaker (or my english is just bad). Really? that CSC is associated with T-Mobile? now I'm getting more confused because the box is stated AT&T and it's sealed.
I'm using Singapore SIM card (Singtel), so you were saying this set I'm using right now is a Multi-CSC device? If i were to flash to the other carrier firmware, will it create any problem?

Flashing Singtel Firmware won't work since it's configured for the Exynos SoC. Multi-SIM Devices have only regional Service Providers available, you don't have Singtel as an option in an AT&T device. Based on your situation I would consider one of two options. The first would be insert an AT&T SIM just for OTA updates. Not sure if you received an AT&T SIM when you purchased the device, if you didn't they're not hard to find. The second and likely best option is sell the device and purchase a Global Variant with a Snapdragon SoC, you'll receive updates regardless of your Service Provider. If it makes you feel any better there's lots of users in the same predicament. They want the Snapdragon device in regions selling mainly Exynos devices. Workarounds are in many situations are challenging,

Your device has Multiple CSC's which are included in OYM so you should be able to change your CSC to ATT, which is the CSC for AT&T.
Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press the Dial Icon, you should see a screen with the list of available CSC codes for your device. Select ATT and tap the Install option.
Be aware your firmware isn't AT&T, it's unbranded so even if you change the CSC, full call functionality may not be available. You can obtain AT&T's firmware at SamMobile.

I have the exact same phone and using the same network as garyHal, unlocked 988U1/OYM/ATT.
I got my bootloader unlocked and decided to apply the ATT firmware (
G988U1UES1BTJ2). My CSC was already ATT so I didn't perform the csc install step.
After setting the phone up as new, it still seems like its running the unlocked mode. I don't see any kind of branding or extra ATT stuff that may have been downloaded. How do I verify that I have the right firmware and CSC set to ATT?
Thank you.

How did you manage to unlock your bootloader since US Snapdragon variants are locked down pretty tight? I don't think the firmware is dedicated to ATT, it's Multi CSC, designed to function with a number of US Carriers. You should be delighted you're not suffering with ATT bloatware! To check the Active CSC go to About Phone, Settings, Software Information, Service Provider SW ver. On the bottom string the first three letters are the Active CSC on your device. You can review this article for additional information on Firmware and CSC's.

If I am reading it correctly, this is what I am seeing:
ATT/ATT/XAA
I am happy that I don't have the ATT bloatware but I also feel that ATT is locking me out of some of their features because I don't have a "branded" phone, such as wifi call or visual voicemail. Am I misunderstanding your post from above, #6, that flashing ATT firmware would give me the carrier features?
Additionally, does the firmware determine what frequency bands I am using and if I am taking full advantage of ATT's offerings?

Flashing ATT Dedicated Firmware would give you the best chance for additional call features ASSUMING your Ulocked Device is capable of incorporating those features. It should do the trick since the hardware is identical to an ATT device. I would head to an ATT Store to get a definitive answer. Samsung has made it more and more challenging to mix and match branded and unlocked devices with CSC or Firmware modifications. In many cases you won't know until you try. Users want their smartphones to be smart, to work perfectly in every situation but the major carriers use proprietary tools to hold clients hostage.

Your Service Provider's CSC is "ATT" which is different than the CSC in your device. Whether or not you can change the CSC depends on your device's CSC. Device firmware is always configured for the specific, original CSC or Multi CSC's.
This post may be the best workaround.

What a trick bro
It's a link for firmware updates
I need to know which one compatible with my note
And after flash will still unlocked?
Hello,
I am new to the unlocking stuff.
I just bought a used ATT Note10+ 5G in Malaysia, model SM-N976U
However the security patch was stuck in May 2020. It could not be updated over the internet or Smart Switch PC.
It says it is the latest s/w (the latest should be July 2020)
I checked Sammobile and discovered 2 firmware updates : USA(TMK) and USA (T-mobile)(TMB)
(tried to include sammobile link here but was disallowed due to new user status)
Which firmware is suitable for my phone?
Is there a way to unlock ATT and receive the normal monthly security update over the internet automatically?
(i saw Odin in youtube and have basic idea how to flash it)
Appreciate any advice. Thank you

A thread already exists with the answers to your questions.
https://forum.xda-developers.com/galaxy-note-10+/how-to/att-note-10-5g-n976u-firmware-files-t4059721
No unbranded firmware version exists as of yet.. so you will have to flash a carrier specific firmware.
https://forum.xda-developers.com/showpost.php?p=81981925&postcount=3
Thank for for the link provided.
Based on the link information, i can download the 4 base files from sammobile (either TMK or TMB) and add USERDATA ATT N976USQS3BTF4 to flash it.
Is that correct?
I could find USERDATA ATT N976USQS3BTF4 in easy-firmware website with a purchase fee.
(editied: My phone Active CSC Code is XAA, CSC Country is USA)

Hi SCitta,
Fellow Malaysian having the same problem as you. But my problem now is that I have Odin and the latest firmware (XAA) but Odin is showing failed to establish connection. How did you do it with yours?
Am using the AT&T version of the Note 10+.

Never experienced the failed connection before.
Have you installed the SAMSUNG-drivers ? The Samsung Smart Switch PC installation might help to fix the drivers.
Hello everyone I am Malian and I live in Mali I recently bought a n976U locked by at & t since when I was putting a chip from an operator from here I was getting network unlock code So I looked for a way to unlock it for free if possible its like that I stumbled across your forum and read your posts and saw the code * # 272 * Imei # like we could try to change d 'operator with therefore when I put my chip it says "Invalid Sim card inserted" if I try to retype * # 272 * ... # it comes out nothing I'm lost please help me s 'please if possible of course Thank you

Just want to share my experience in this. Bought an ATT N976U from the US and using in Malaysia. Phone came with XAA/XAA/ATT and never received OTA updates.
Downloaded Google phone app and changed CSC to TMB/TMB/ATT using *#*#27262826#*#*
Voila. Received the OTA updates one by one since May2020. Am now on N976USQU5EUC2.
Volte is also working on Celcom.
Did not have to flash firmware. Data not wiped. Everything seemed to be working normal apart from "Tips and Help" in settings crashes every time I click it. Also phone boots with T-Mobile logo now.
One of our Chineese suppliers has gifted me a New Fold 3. The issue is the stock Chinese Rom, or rather the restrictions that come with it (nerfing most google based services, and apps i use all the time.). The device is great but restrictions applied give you a feeling of a second class android user, with core sevices absent: Play store, youtube, gmail, maps, chrome, android auto., can't even apporve family link download requests from kids. etc. etc.
I have made the choice i would rather go back to my S21 if i can't resovle this issue, as phone is useless like this.
Advice required on Loading Australian Rom via odin.
The phone model is: SM-F9260 which only seems to have overseas Rom available for download. Can i successfully load a ROM made for model SM-F926B (Australian) on a SM-F9260?
All the how to guides specifically say jou must select the same model number, and i don't want a brick it. Will have mud on my face next time i see the supplier if i have bricked their gift to me.
Any feedback/advice from users with more experience with odin and flashing would be appreciated.
Both are on Snapdragon CPU so shouldn't be any problem to flash it with PIT over the Odin.
But I never done it so I can't give you 100% answer.

Update: The AU version gave me an Auth Failed in Odin. Chances i could have resovled by unlocking the Bootloader which i didn't want to risk tripping the e-fuse. I ended up just using the Taiwan version which had the identical model number, and falls in the same region as China. Odin flashed without complaint. The taiwan version has no restrictions on google services, and once you set the language its hard to tell it from a regular AU one; unless you know what you are looking for that is.

Technically there are ways, just it is very grey as to when/how you trip the e-fuse. Some say if you simply unlock the bootloader and restart, others say when you load a bootloader that doesn't match model numbers, or is older than your current, or isn't offical samsung one. I personally don't know exactly. I do however know that i didn't trip the e-fuse when i loaded the taiwan version, and i didn't have to unlock the bootloader in developer options to achevie this.

oh. Good to know. Just wondering..Did you trip your e-fuse? If so when did it happen? Did you try extracting the PIT file from the CSC and using the PIT tab in odin? with the re-parition option selected?

you won't have the chance to trip. there is some check before the boot image is integrated. so it failed showing some error, auth or secure check failed etc etc.
if you flash variant home csc you will trip
TBH, I consider the Chinese version is the best version above all other region. The dual sim is enable on Chinese version, 512GB is the only available option.
As for google service. You don't need to change the Chinese firmware to Australian to enable it, the GMS is pre-installed. All you need to do is to find a way to install the google series apps as apk by yourself, it would work just fine.

BTW, the only version that Chinese region Fold 3 can change is the HongKong firmware, all other regions are not available. If you use Chinese region Fold 3 in Australia, the only thing you need to concern is the Samsung Pay, but Samsung Pay is fixed by the region and cannot be changed by switching the regional firmware.

Each to their own, if you like the chinese version great. I hated it, restrictions in every aspect of the firmware. I personally am unsure how you rate the chinese version better, when it is loaded with restrictions and hard coded settings that can't be changed, or if they can it is really a sub par workaround. Settings that are not present in standard android builds. What exactly does it have extra that makes it better? If you like it thou that is all that matters.
I loaded the taiwan version which yes is really just the hong kong version. No restrictions, no issues. Now it works just like any other standard samsung android build, you get in AU. Yes samsung pay that use the firmware version doesn't work great, but i prefer google pay anyway. No need to stuff around with downloading apk files from third party sites, for core functions. No need to even enable developer tools.
The chinese version sounds like driving a ferrari on a go karting track.....
Can you flash the Chinese or any international dual sim version to work in the US ?
