OS for SM J327P - General Questions and Answers

I accidentally wiped the OS of my Samsung Gallaxy J3 Emerge (Boost Mobile). It happened while at TWRP recovery. The phone was bought online from USA. I had rooted the phone and had TWRP recovery. Now every time I start, it shows TWRP recovery but no OS available.
I had tried to install two firmware via twrp but failed. Did I use the wrong firmware or the problem is something else?
Please help and advise me on the possible solution and if so the right firmware for this device. Thank you.

You can't flash the firmware via TWRP.
This is the reason why we always make a big deal out of creating a nandroid backup of your stock operating system in TWRP BEFORE making any kind of modifications to the device. If you had created a nandroid backup, you could restore that backup to fix your device.
Since you didn't create a backup, you'll have to flash the stock firmware for your specific model number via Odin to get the stock system working again then start over with installing TWRP and root again.

Thank you sir for your reply.
I thought I created a nandroid backup (but still looking for it), so if you could provide important instructions how to restore that backup in case I finally find it? Yes I installed those two firmware (mentioned above) via TWRP and also via ODIN but failed.
I had problems in figuring out the right firmware for this particular device and also where to get it from, so if you can help me with this I will be very thankful and grateful.
Thank you again.

Anyone can help me on the exact firmware for this device and where can I get it? I'm still searching for it online but hope what I look for is correct. I have downloaded two firmware but failed with Odin. Thank you.

It isn't complicated, go to Sammobile .com or samsung-updates .com and enter your specific device model number in their search feature. That should give you a list of all available firmware for your model number, then you just choose the newest version that has the correct 3 letter code for your region, country or carrier.
If you don't know the correct 3 letter code for your region/carrier, try doing a Google search for:
"Region code for (enter your country and your mobile carrier)"
That should show you the 3 letter code that you need, then look on the list of firmware for your device and choose the newest version that has the correct 3 letter code for your region/carrier.

Thank you for your reply and time, I really appreciated it.
I had tried what you said, and here's the results:-
1. Sammobile.com has no search result for Galaxy J3 Emerge or SM-J327P.
2. Samsung-updates.com has 14 firmware available for my device i.e Galaxy J3 Emerge (please see screenshot I attached).
I was confused and couldn't find the 3 letter code for my region, country (i.e Kiribati) and carrier (i.e ATHKL) when I googled it. I suppose the 3 letter code you mean are something like SPR, BST, VMU, etc.
May be I can try the ones (firmware) with BST USA since my phone was purchased online from USA. The phone was also unlocked and always booted up with Boost Mobile Logo even though I had been using the sim from ATHKL - the network carrier in Kiribati. That was the information of my phone before the problem.
I always appreciate your help, advice and recommendations. Thank you.

Flashing the Boost firmware should work, after flashing the firmware, if the radio(modem) isn't working or allowing cellular or mobile data connection, you might need to flash a different modem that has been extracted from another firmware for your model number to make the device compatible with the networks where you live. If it needs a different modem, you'll have to do some research to see which modems for your model number are compatible with your network.

No, SPR stands for Sprint, BST stands for Boost, VMU stands for Virgin Mobile, these 3 letter codes are not the region codes I was talking about. These are 3 of the major US carriers. The 3 letter region codes I meant are listed in this link below. Kiribati is not listed, your country is probably considered to be in the Indonesia or Malaysia region or some other south Asia region.
https://forum.xda-developers.com/android/general/samsung-android-csc-phone-tablet-t2949229
Here is a firmware that should work for you, it is a generic firmware for USA devices designed to work on all USA networks. I'm giving you the generic firmware because flashing a firmware for a specific carrier may brick your device if that specific firmware is not compatible, such as flashing a SPR firmware(CDMA network) when the device was meant for BST or VMU(GSM network).

Galaxy S4 i9500 Origin

In July I went to New York and bought an Galaxy S4 i9500 and messing around with the device I corrupt the EFS folder losing my IMEI.
Since it wasn't bought on my country (Brazil) I don't have any support nor warranty so I send it to a friend who owns a service box ( octopus probably) and flashing the ROM he asked me what is the country of origin of my device, since I bought in the US and this model in particular isn't supposed to be selled there I don't know wich country it came from and can't fix my device. The back label says it was made in china but i guess every other phone in the world was made there too .
(I bought it from the Samsung stand in the 5th ave Best Buy so it is original)
No problem
In phone setting option there is baseband version and build number from there you can find out where the device is from originally manufactured.
But now I think you have flashed other firmware and that original information is gone.Corruption of efs folder can be from many ways either flashing roms or wiping full internal memory by not following appropriate methods corectly.
You could have make efs backup in first place before experimenting with the phone.
But now you can try the following methods.
Try to flash latest modem to see if it help through odin.
One other method is that you can find your country of origin by your imei no which is on the box. Just call or email Samsung customer service in your country, I did in my case and they can tell you from the imei number the country of origin.

Ok Try to flash stock firmware and see if it helps and do tell me if you succeed.
You should be able to flash a stock firmware through ODIN and have the phone working again.
Then as mentioned above, before doing any work on the phone you should do a EFS backup, nandroid backup.
I remember with my previous phone (Galaxy Infuse) i was learning also how to root, tweak, modify the android and also "killed it". I was able to resurrect (in a manner of speak) the phone by loading the stock firmware the phone had when i first got it.
Good luck!
My friend said he repaired the device through the octopuss box and are sending me back. He couldnt upgrade to 4.3 because he didnt know the country of origin (like I said before). I call samsung to ask if they could say to me but here in Brazil the only company that really helps trough phone is Blizzard so I ended where I started. I found a website that using your serial number or IMEI can say where your device are from and I for my surprise it is indeed a chinese Galaxy S4. In Sammobile I found the CHN firmware that matched the time of fabrication (July) and probably its the stock firmware that I was looking for and one of the ones that I didnt tried to flash at the time.
The thing is now I'm too scared to try flashing this one to my mobile and ending ruining the device again and once more being forced to use my old ****ty iPhone. Any sugestions for me guys? (The device didnt arrive yet... i knew the serial and IMEI 'cause i noted down)
You don't have to flash firmware for country of origin. I'm in New Zealand and flash firmware from all over the world, the latest was UK firmware, with a modem extracted from Austrian firmware.
Just go to sammobile and make sure it's for i9500 and you'll be fine mate

What is the serial number of your phone? You can find it by beneath the battery or in settings, about device, status.

It's below the battery, next to the IMEI. It is a combination of letters and numbers and looks like this "S/N: XXXXXXXXXXX" (X= Letter/number)

Looking for CORRECT Xfinity Mobile Samsung S8+ Firmware (CCT)

Hello everyone,
I am looking for the stock files for Xfinity Mobile. I can't seem to find them anywhere. I'm assuming because they are a new company no one has them really posted. The Only files I see are "no boatware" versions, but I actually need the true "xfinity" Version. Of course I have check Sam's and other sites, but they all have the incorrect information. By any chance can someone send me the correct firmware? (pulled Directly from your own device)
Thanks for any help

Using the SM-G955U model number and the CCT CSC gives the following results:
G955USQU1AQEH/G955UOYN1AQEH/G955USQU1AQEH/G955USQU1AQEH
So there is a firmware available, use SamFirm to download it and flash using Odin.

Download SamFirm.
Enter SM-G955U model number and 'CCT' as the CSC, it'll take a few seconds to check and then present you with the firmware details and the download button. It'll save somewhere on your PC, extract it, follow the guide I linked above and you can have the CCT firmware on your phone.
The fw.updato.com site has it, but it's being glitchy right now, so it isn't giving me a direct link. Use SamFirm anyway, it's faster and its much easier to find the latest firmware.

Cheers.
I have a SM-G950U1 and I am trying to get a new XFinity Sim card to work (it does not connect to data right now). I tried using ODIN to install new firmware but that did not help. I just noticed, however, that the firmware for the SM-G950U model allows you to select the provider, but the SM-G950U1 firmware does not. Could this be a problem? I can't find firmware for SM-G950U1 for Comcast. Should I try installing the firmware for the incorrect model ( SM-G950U) so I can specify the carrier?

Flashing Stock Firmware Failed

I have the SM-G955F.
I flashed TWRP using the instructions on here and everything worked perfectly fine. I even booted back into the stock OS - however, the Magisk app was not there.
I was going to boot back into TWRP when I got the message "Only official released binaries are allowed to be flashed" and went into a bootloop.
Then I followed the instructions to flash the stock firmware back on to my S8+, but it failed. Can someone point me in the right direction please?
I used Odin3_v3.13.1. I have attached 2 pictures to show the error.

Sounds like you are trying flash older firmware than what is on your phone. Odin saying you are flashing firmware with bootloader ver 3. Download mode saying you have ver 4 bootloader. You will need latest version of firmware with ver 4 bootloader or higher and flash with Odin.
Bootloader version number is 5th number from right of firmware name.

Thanks so much for responding. So from my reading and researching, I figured that was the case. However, I could only find the the official firmwares from here:
https://forum.xda-developers.com/galaxy-s8+/development/rom-galaxy-s8-t3749444
Which happens to be v3 bootloaders. Is there any specific v4 bootloader that I should be flashing? I am at my wits end here. I followed all the instructions perfectly...
I read that everything works fine until reboot then you get the "Only official released binaries are allowed to be flashed"

Firmware can be download from sammobil or updato and flashed with odin
https://www.sammobile.com/firmwares/
https://updato.com/firmware-archive-select-model
Select phone model then search for firmware for your region ( and carrier ).
Only official binary error is probably due to your rmm state being in prernormal state which means if you unlock your bootloader ( oem ) and reboot it will relock bootloader causing this message.
Reflash firmware to get phone running again.
Have a read through this guide for more info about rmm state

Thank you for the links. I can't tell you how much I appreciate you helping me out.
I bought the phone from eBay, it's a SM-G955F - as for the region and carrier, I live in United States using AT&T. My primary reason getting the international version is to install a custom ROM on it. Is there a specific firmware for my region (U.S.) and carrier (AT&T) that I should flash? I don't see it US listed.
Also, using the guide I mentioned above, I did flash the RMM bypass, however, it was not the version 2, found in the guide you posted. Is that where I messed up?

I don't live in the US but there should be filters on the websites to filter by region. I normally use updato and firmware for your region shows up under U.S.A it will show you all your carrier's like at&t, Sprint, t-mobile and non carrier firmware.
As for the rmm zip version 2 may have been better it is more up to date and is smaller in size. Both should do the same job though.

I looked on updato and sammobile, both do not have USA region. Can I flash firmware from another region and still get it to work on my carrier?
For example, can I flash U.K. (Vodafone) since its on ver 4 firmware and uses GSM - regardless of region and carrier?

Just doubled checked saw you have the f series while updato has u1 version firmware that I can see.
You can flash firmware from the UK if you want but can't say for certain you will have full network capabilities due to the difference in region and carriers ( network capabilities ). I would try and find an unbranded version ( non carrier branded) firmware first if not then something like Vodafone .
There is a simple reason for this. If you came from TWRP as "reboot to download", this creates the problem. Turn off the phone. Go to download mode with Vol_Down+Bixby+Power and then press Vol_Up button. When I enter download mode like this, it flashes without any problems.

How To Guide F711U and F711U1 Firmware Links and Flashing Discussion Here

(WIP, files are currently processing and uploading)
For those who aren't already aware, F711U is the model number of all of the US carrier versions of the Z Flip3. The F711U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I have access to an internal Samsung firmware download tool that usually gets new versions before they hit the public firmware download tools, so that's where my files come from.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!

U1 firmware: https://www.androidfilehost.com/?w=files&flid=327753
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- it's quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single flagship model, so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit the firmware download tools.
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:
AIO = Cricket (not available via firmware download tools)
ATT = AT&T (not available via firmware download tools)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
DSH = Dish Network
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via firmware download tools, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
Flashed a physical T-Mobile F711U to a F711U1 XAA firmware using Odin(Can't stand the bright pink boot up animations).
Flash worked perfectly. But, when I tried to test doing an update from Google settings it failed every time with "Registration Failed". I flashed the device back to the T-Mobile F711U firmware and was able to update without issue.
Not sure if you ran into this issue, but it's worth noting you might not be able to update the phone if the carriers are checking the Firmware.
Edit: Also forgot to mention, had to use the patched Odin due to the Firmware Model mismatch. Phone does work properly though.

From "Settings" App > "Software Update" > "Download and Install" and pressing the "Download and Installing.
I get "Connecting to server" and then immediately "Registration Failed" I've attempted over Wi-Fi and with that option toggled off.
This could also be the phone is new and T-Mobile doesn't have the F711U1 XAA firmware at their carrier level, but the registration failed annoys me. On F711U (official T-Mobile firmware) I simply get a notification that the device is up to date.

I flashed my phone using the F711U1OYM1AUG7 (F711U1 XAA) firmware from sammobile.
I flashed it back to the T-Mobile firmware, (F711UOYN1AUGB (F711U TMB) and the issue went away.
I did flash it again to the XAA to confirm the problem this evening. Never retained data during the process. Factory reset and removed my account information (Google and Samsung) before updating the firmware each time.
I've done this on a few phones in the past. If I'm making a blunder in the process causing this then I'm truly sorry for wasting anyone's time.

Well UG7 is the latest that's available. So yes, I would expect you to get an error.
Once an update is available, if the phone is still giving the same error, then you can worry about it
Hello, well from my understanding Xfinity is bootloader unlockable after 60days and fully played for. I am wondering if anyone is planning on making a thread for Xfinity specifically. Or want too work with me on One. Sorry too spam or thread. But if u are familiar with how rom building, and flashing was with any other recent samsung model/Xfinity/bootloader unlock. It would be highly appreciated too know your experience.

Incorrect. No US models of any Samsung device have been user-unlockable for years now, dating back to the S7

I think network unlock got mixed up with bootloader unlock. You can unlock the phones for use with another carrier after X days and completed payment.

Well normally I would say that you can get it yourself from the various firmware download tools like SamFirm or Frija. But it looks like Samsung changed something over the weekend, as the current versions of the tools are failing to pull any firmware
So I can grab it for you

1. Thom Browne *is* U1 firmware
2. USERDATA belongs to U firmware, not U1. So I have absolutely no idea. You'll have to try it and see what happens
Have successfully flashed F711U1 to F711W. Everything working fine. Used Odin 3.14, CSC_OMC_OYV, and working on Telus with all available features working.
Please note that AFTER the flash, you will be prompted to reset the device to stock. Reason being is that it needs to install the appropriate CSC linked to the inserted SIM card.
Can anyone confirm if cross flashing different build firmwares that it will unlock the unlock bootloader option?
Currently on carrier firmware for TMobile and I'm wondering if this is possible or if the u1 firmware has the unlock bootloader option available

Question Change Service Provider Software

Hi all,
I bought this phone from my friend who was using it on ATT. It is global unlocked phone and I activate and register, change new 5gsim and no problem on Verizon Network.
It is working and fine but, it shows ATT logo when phone is boot up and still it has ATT bloatware.
Under the Software information > Service provider software version is showing below
SAOMC_SM-F711U_OYN_ATT_RR_0016
ATT/ATT/ATT
SO THIS PHONE IS legit!! even Verizon told us. They did everything with me for 3 hours. wow!
Anyway, I think it's the problem of other carrier's software is in
Do you guys know how to change provider software to Verizon? should I contact Samsung??
Please help me.
Thank you!!!!!!!!

I even flash with factory reset. Yes, I used Odin 3.13.1b patched and it passed...

@iHeartslutsz https://www.sammobile.com/samsung/galaxy-z-flip-3/firmware/#SM-F711U1
Whenever I flash a new software through Odin after downloading it from Sammobile, the Dark Side RC theme (I think it's related somehow to the so called Star Wars special edition) for samsung, comes as one of two default themes into the system and can not be removed. Hence, even I change the theme from setting, this iron head appears everytime I restart the phone for a few seconds. So I tried different firmwares for my country but nothing changes. So someone from another forum said that my service provider software version differs than theirs. So in short, how to get rid of this silly iron head? Any help would be appreciated.
change csc, use SamKEY (paid) or SamFwFRPTool (free), then flash frimware you need with odin with CSC file (this will wipe your phone and reset to factory), not use home_csc in odin

Thank you. I downloaded totally different firmware files with different CSC code and the problem has solved.
SamFwFRPTool is a tool I use to change my CSC software channel. The way I understand it you need to change the CSC in the program before flashing the u1 software on it so you get a full unlock as opposed to a partial one.
I might be wrong here though so don't take everything I say as being true.
