So I have a rooted Galaxy J7 pro with me (SM-J730f/DS)
This phone was rooted and it was blocked at boot showing "Custom Binary Blocked by OEM Lock"
I went into Odin mode and there wasn't anything that showed a country code. So I downloaded a stock rom according to my country and it's carrier was open (which I thought meant any carrier, I mean there ain't any career named "open" in my country) So I flashed it using odin, everything went smooth. The phone is performing well but after inserting sim cards, it detects the sim but doesn't work. Shows "unable to connect" and "error while connecting" when I tried to set network manually.
I probably should now flash the correct firmware but I don't know in which country this phone belongs. I dialed *#1234#* but I obviously got the information about the rom I installed.
In the back of the phone "UK" is written after the model number (SM-J730F/DD, Samsung, Yateley, GU46 6GG, UK) but I couldn't find a UK rom. I looked into Imei.info but couldn't find any info about region.
Is there anyway to fix the issue other than trying every J7 firmware there is

Okay,where do I start.
So I bought this phone off a friend of a friend(I was going to sell it on for profit as it was a good deal).
I noticed when trying to update that it was telling me it was an unauthorised software, so i took it the device was rooted.
I then factory reset the device to see would it go back to factory settings, but just stayed on the custom firmware.
I then decided to flash stock firmware onto the device from Sammobile (device boots up with Three logo so I assumed it was with Three Ireland network so that's the firmware I chose.
After flashing the device it boot up with a dm verity error and would only go as far as the Three logo. After some research I found a discussion and followed the steps in this, flashing a file called CF-Auto-Root-zerolte-zeroltexx-smg925f. After doing this the dm verity error had gone and the phone booted up fine.
I left the phone like this, as I was going to sell it at a later date. Before I sold it I had one last test of the device and noticed it would not connect to a mobile network (I don't think this issue was there when I first got the phone as I am nearly sure I tested my sim card in it, but cant be sure). I just kept getting 'not registered on network' error.
After some more research I downloaded the Samsung info app and ran it. I then noticed a few strange things.
1). The serial number of the device was just showing up as a string of 0's.
2). The imei number that was listed did not match the imei on the back of the phone.
3). The carrier was showing as O2 UK, but Im not sure if this is an issue as O2 and Three are basically the same network here in Ireland (Three took over O2 here).
After doing an imei check, I found the imei listed on the back of the phone to be fine and was showing all the right details, serial number etc. But the imei that was listed as the imei of the phone, in settings and using *#06# was showing up as not existing.
I found this very strange and I'm sure this has something to do with why it can't connect to a network.
Any suggestion on getting this device back working properly as it is just a paperweight now as it is, and after spending money to buy it so I could sell it on I don't want to have wasted that money for nothing.
Any help is appreciated.
Thanks
Nothing? ?
Phone displays "Network Locked SIM Card" Inserted after flashing a stock firmware
I recently uninstalled Magisk, and was able to only boot into download mode after. So, I downloaded a stock firmware for my s9+ 965f and flashed it through odin (using AP,BL, CP, CSC(didnt select HOME CSC). But after rebooting, the phone displays "Invalid SIM. Network Locked SIM Card Inserted".
It asks for PUK code to unlock the phone and the cellular service alone is not working now. My phone is already region unlocked and I have been using it for the past 8 months. Has anybody got this issue and any suggestions on how to solve it?
Previous OS: soldierx rom for 965f v12 on Oreo
What I did,
i) uninstall all modules in magisk,
ii) uninstall magisk,
iii) phone auto-reboot
iv) Now phone stuck in download mode. Cannot boot it
v) downloaded stock firmware G965FXXU2BRGA
vi) flashed through Odin(AP,BL,CP,CSC)
vii) Phone completely formatted and boots up.
"Error:Invalid SIM card inserted. Network Locked SIM card detected "
I am now being asked for PUK code or cellular service wont work
You need to contact your carrier for PUK code, its protective measure against too many wrong PIN attempts on specific SIM. Can't fix that with any flashing.

This is where the problem is. You put any sim card in that phone, you get the same error. The sim card works fine if I put in any other phone. I am not sure but unistalling Magisk has caused "SIM Card Read Error" in my S9+. I even upgraded to Pie from Oreo and flashed 3 different stock firmwares but the sim card error exists.
@topjohnwu
I would appreciate if you can help me on this. Not sure how to fix the issue
Looking up the error message itself points to some sort of network/carrier lock. If I am reading regional lock and carrier lock definitions correctly the two are not the same..
Did you have the phone network unlocked or was it network unlocked when you had root installed? If the device was network unlocked when it was rooted and you flashed back to stock (which removes root) this might explain what is going on...

This is an unlocked phone. I had magisk installed and when trying to uninstall it to upgrade to latest magisk, the device wont boot except download mode. So, I downloaded stock firmware and flashed it. Once I boot up with the new stock firmware, I get this error
There is some sort of lock on the phone, which is why your being asked for the code.
I think you should definetly try was what was suggested above.. trying to contact the carrier and see if they can give you the PUK code. If I recall correctly you get a few tries to enter it correctly before it won't let you anymore (and it might lock the phone up good or damage the sim)
I'm having a similar issue on a Verizon A50. Any progress?

depending on what method was used to unlock it, its likely no longer unlocked. some sellers of unlock codes neglect to mention that part. im betting its locked again
I’m trying to flash the firmware on a S6 edge (Android 7.0) in the hope I might get wifi calling calling on Three in the UK as there’s no mobile signal where I live and the 3inTouch app I’ve been using is discontinued. I’m on PAYG which is perfect because I’m a light user and Three’s credit doesn’t expire.
I used Odin successfully to install BTU firmware from Sammobile but that doesn’t give me wifi calling. But when I try to install H3G firmware for Three I get a failed error in Odin and a “SECURE CHECK FAIL (BOOTLOADER)” error on the phone. I’ve tried various versions of Odin and firmware from another site but all failed. USB debugging is enabled in developer options.
I found a thread where it appeared someone managed to get wifi calling working on an S6 using Kies to enter the model number and serial number of the phone and then was then offered a menu to select the firmware he wanted to install. I tried this on a separate pc (in order not to interfere with Odin) with the newest version of Kies I could find that gave me the option to enter the model & serial number. But this gave me the error “SM-G925F does not support initialising”.
So is the only solution now to root the phone, which I’m reluctant to do because of security? If I do root it and manage to update the firmware is there anything I can do to make it secure? And if I give up and buy a new unlocked sim-free phone (S7 or above) from Amazon or elsewhere will wifi calling work or would I need to be flashing firmware again which I don’t really want to do on a new phone.? Three's website says it has to be bought from them.
I should also have said that OEM unlock doesn't appear in the developer options
Hi all.
This is my first post and will try and make it really quick.
I recently got a Galaxy Note 5 (because their just amazing) It came with Android 6.0.1 installed and the "Software Update" section of the settings menu does nothing. I mean literally nothing. I tap "About Device" then "Software Update" and nothing happens no new screen loads or anything.
so I was looking for the OEM ROM's and this is where I ran into so much confusion. The current details the phone gives me is.
Galaxy Note 5 SM-N920F (There are no F rom's)
Build Number MMB29K.N920FTMB4DPH2
Bootloader N920TUVS6ERH1
Which lead me to believe even though their is no "F" variant, That its a T-Mobile model (No Rom's really give 100% functionality to these except the standard 7.1 from T-Mobile)
So I went to Sammobile.com to download the latest official firmware released, But the the CSC numbers don't match my device. they are all starting N920TT***** and mine starts N920FT*****. However the PDA numbers match my bootloader. So will any Note 5 T-Mobile ROM work even if the CSC numbers are different? as long as the PDA numbers are the same?
I get more confusing info from Samsung as well. The "Samsung Members" app shows my Model number as : SM-N920TZKATMB (Which again has no "F" in it, The sticker on the back of the device with the IMEI even states it as SM-N920F)
Am I making this weirdly complicated for myself? Will the US T-Mobile ROM's for android 7.1 work find I flash them with this device? (I live in the UK and the device has 100% compatibility with my network)
Also will flashing the stock 7.1 US ROM from T-Mobile re-lock the SIM ? I'm pretty sure it doesn't/Cant relock SIM to T-Mobile only, But nothings better than a professional confirming.
There is also another issue. according to "Root Checker" I have a Rooted device. But their is no Super User apps on it at all (Cant seem to even find Binaries for SuperSU when using Root File Manager), Pokémon GO fails to load which I have read could be because of the "Root Check" throwing up a positive. But no other apps fail to work at all. their all perfect even banking never even so much as an error. it is just Pokémon GO. Or has someone previously messed up rooting so it looks like it is but the files are missing and isn't really? I tried using Magisk Manager but it did nothing and I don't get any prompts for Root access when installing apps.
So Please Help Me! Thank You.
I have been at this issue since Saturday and gone through a lot of possible solutions but to no avail. So first of all i am in Ghana. A friend came to me with his s6 edge that he had some issues with his phone going off when he unplugs the charger and getting stuck in a bootloop when turning it on unless he plugs a charger in before it boots up fully(even with full charge)
So first of all he wanted to do a factory reset(phone was not rooted). Factory reset completed successfully but issue still persisted.
Specs of the phone was:
android 5.0.2
model number = SM-G925F
original csc (i wasnt able to note that down because downloading stock firmware was going to be the last ultimate weapon. first i was going to try some custom roms to see if it fixed the issue. Besides it was working fine here in Ghana.)
So that's when i flashed a twrp and i dont exactly remember but i think i might have tried to flash a lineage OS or something. But long story short, when u try booting up, the samsung galaxy edge screen with powered by android came on and stayed there. and it did not go on to boot up.
After trying through the night i then decided to use the ultimate tool and flash a stock firmware. Try as i might none of them got past the "Repartition Operation Failed" portion of flashing it. The Pit File was becoming an issue. Tried firmwares for my country, countries nearer to us, contries in africa and finally even european firmwares. And since from reading from here and other forums that the F variant was an international version the international pit files should work but they werent.
All this while whenever i go to Odin Download mode on the phone, the product name there was SM-G925D. This started the confusion because at that point i had looked through alot of firmware and that was not an option. When i searched google for that, the search results mostly correlated it to SC-04G, which looking at it was a Japanese firmware. I didnt want to use a japanese Firmware for obvious reasons. At least i wanted a firmware that was by default in English. But after about 2 days and seeing a lot of answers saying stuff about going to settings and checking stuff there plus me wanting to see an interface and work my way from there i succumbed.
And lo and behold, it flashed on the first try(i used the 4-part files firmware. It was android 7.0). But when it came to booting up, the splash screen had changed from samsung bla bla bla powered by android to NTT DOCOMO powered by android. But it booted up and i skipped through the setup. i had to change the language to english but there were a lot of japanese bloatware that came with it. But as i expected when i popped a sim card into it, and restarted the phone, there was the not available symbol(circle with a bar across) where the network bars were supposed to be.
Seeing that this was not going to do, i went to the settings this time to check on any important details and this were the new details
android version 7.0(January, 2018)
model number=SC-04G
build number was now SC0.....(cant write the full code as im currently in odin mode)
But obviously it was the japanese network. After this i have downloaded more firmwares and they all fail at "Setting PIT...Re-Partition failed". Somtimes i try to mix the 4 files up using maybe the CSC portion of the Japanese firmware but BL, CP, and AP of firmware from my region. This time the error is "sboot.bin failed".
And that has been my grind till now. Downloading likely firmwares and all failing to doing extremes like the mix and match. When the mix and match with BL, CP, and CSC of Japanese with AP of my region works and eventually boots up, there is no touch input. The touch does not work. When that happens i just have to start all over with the SC-04G, which never fails to work.
I have even seen some things about changing csc files in the file explorer with root so i flashed the Japanese FW and rooted it. Went through the processes but to no avail.
PS:
The first part of the Odin screen where you choose to continue or reboot is now completely in Japanese whiles it was formerly in English.
And there is no indication on the phone itself that it was from Japan. The back says Samsung and below it says Galaxy s6 edge. Friend bought it from a shop in Ghana here brand new.(not from a carrier)
****So here lies my confusion. How come a phone with an original model number of SM-G925F have a Product name of SM-G925D in Odin and hence only Flash Japanese Firmware SC-04G(CSC code = DCM) but would not flash any of the international variants. Even if i can eventually get the Japanese firmware to read the sim card we can manage it that way. But thats for when there are no options left.
So please i would like to know your ideas as to how this is happening and any possible solutions that might be different from what my batallion of open tabs are telling me. You can also let me know if you want any more details i might not have included. Looking forward to hearing from you guys.
Update On Issue
I ended up using the japanese firmware in the end because it wasnt picking anything else.
This time after the setup process, it picked up the sim card and the imei is available. So since network is now available i just rooted it with cf autoroot and removed the japanese bloatware and everything looks normal now.
Except the original issue of going off randomly whn power cable is pulled out even when having full charge.
:good:
