N5100 New MotherBoard from China, CSC CHN, Need Help Loading ROM

I have a Samsung Note 8 inch. Tablet. 2012 model.
N5100 INU version
The original Motherboard got corrupted so i installed a new motherboard Ordered it from China / AliExpress.
As soon as I installed the new MotherBoard everything works fine. /
UPDATED Info
It was with Custom Firmware / CHINA Official . but device Status was Custom, I did not try to load Chrome/ GoogleFrameWorkServices APK. On this firmware which came with the mother board, but i did see some info about that.
The issue is they ship with China Firmware
I need STOCK INU firmware on this. Or any English firmware.
I download the N5100 INU Firmware I allso tried ODIN
I also tried SmartSwitch
I also tried Kies UPDATE / Initialization nothing has been working.
ODIN gives "failed to write / complete error"
SmartSwitch unable to connect unsupported device
Kies same error
I also tried to update/ initialize but the issue is after download 2 or 3 hour of Firmware it goes to 0% and says "failed to update" try to use recovery mode from abother compbuter and ask for recovery CODE.
I know i am missing some thing very small.
I checked the Device is not ROOTED
I see ODIN mode
Binary: Samsung Official
Device Status Custom
Custom Binary Download: NO
Maybe it is locked or something.
IDK
2nd issue
When smart Switch Ask for model and serial
I had 2 or 3 times put the Indian MotherBoard Serial Number
And it had Failed.
Now i am trying to Do this with China MotherBoard Serial Number.
If this time it succeeds i will be happy to inform you.
But this will still only load the Official China FirmWARE for CSC CHN
Anyways After this Maybe i will try ODIN
Since once it will have china official firmware
then it will have India ODN firmware via ODIN
But I could also go into a bad State here..
If the china guys sent me the motherboard with custom firmware which will support all india sim cards and etc. And now if i complete this official china firmware. I might get locked out !!
Dam i dont know what will happen and how i will solve this.
The ONLY solution someone has suggested who bought this same mother board and did it.
Said that " you need to make IMG of the original Country Firmware built into the Odin file and you also need all the files BL / CSC / PD etc.
I want HELP thanks
UPDATE:
Ok entering the China MotherBoard Serial Number smartSwitch installed the original China firmware back.
And now the Device status became
Official too.
That's 1 step ahead or backward idk.
So now I need to install India firmware via ODIN.
I assume if i use SmartSwitch and put Indian motherboard serial and after 2 or 3 hours of download it will not upgrade since it will try to match the serial number.
Anyways I just tired ODIN and it does not work. Same error
Complete (write) operation failed.
Any help please
So FINAL:
I am stuck with Original Official CHN / China Samsung Firmware on this n5100 And I cant do anything
GOOGLE Youtube / GMAIL / Play Store / ETC.
Question:
Is there a way I can load a Multi CSC Firmware 1st which will load VIA ODIN and then Once this is LOADED
I can load INU INDIA firmware ?
I dont know what is the CLASH
Where is the CLASH and CONFLICT hapening for ODIN not working
Thanks Please REPLY HELP ASAP
SideQ

Marshmallow ? Nougat ?
All features working :
GPS /
Camera/
WIFI
SIM Card
Network
Bluetooth
No errors ?

I will still prefer a Stock ROM

Galaxy S9 SM-G960F Dual Sim Firmware Update

Hello,
The firmware of my Galaxy S9 SM-G960F Dual Sim was last time updated in May 2018. I moved from Asia to UK, so that may be the reason. I to update it mainly for security reasons.
I have had a look at Sammobile and they offer updated versions of SM-G960F with my current carrier (Vodafone). Will that work? Is the same firmware for a single sim than a dual sim?
I will appreciate any additional recommendations whether I should update directly to Android Pie or stay in Oreo.
Thanks and regards,

Yes the G960F firmware works for the FD and DualSIM still works fine

A70 (A7050) Struggling to flash HK firmware

Hi All,
I've just returned from China with an A70 (A7050), it's got the stock Chinese firmware on it. I wanted to flash it to Hong Kong firmware to get gapps,etc. My knowledge of doing this is the sum total of nothing and I'm having problems after trying to follow a few guides I found online;
I've downloaded the firmware and Odins
I've populated BL, AP, CP & CSC (used the Home_CSC not the CSC) in Odins
Hit start and got a fail due to OEM lock
Found a guide on how to remove the OEM lock, bootloader now unlocked
Repeated the first steps above
Now get a fail "SECURE CHECK FAIL : abl"
I'm struggling to find information on how to proceed from here or am I just being a total potato and missing something easy?
Any help is appreciated

Have you been able to fix this?
I'm interested how this turned this out for you.

Hi, I forgot to update here but yes I was successful. For reasons I don't understand it wouldn't take the latest HK firmware (the Chinese was the latest at the time). When I tried the earliest HK firmware available it went straight on (and later updated itself).

Did u unlock the bootloader or did u just switch on OEM unlocking?

Change Active CSC Code to Firmware CSC Code

I just got a galaxy s10+ from a friend who was on Tmoblie so it has the Tmoblie loading screen and apps. I would like to revert it back to the firmware CSC code XAA so I dont have to have the Tmoblie boot screen and apps. He didn't buy it from tmoblie its from an insurance company so I am pretty sure its unlocked. The app "Phone Info" says that Firmware's CSC code is XAA and the active one is TMB. I have tried to put in the *#272*IMEI# code into the phone but it just gives me an error code.
Is there anyway to revert it back to XAA without flashing the phone? Will I void the warranty if i flash the phone with official firmware? Also if I have to flash the phone where do I find XAA firmware as I only saw carrier firmware on SamMoblie.
Thanks for any help and very sorry if this has been posted a thousand times!
Also the phone model is SM-N975U / Galaxy Note10+
Device Type: d2q
Product Name: d2qsq
Bootloader Version: N975USQS6FUF1
CSC Version: N975UOYN6FUF1
Phone is on Android 11

I just flashed the phone and it all worked out. I used these threads to figure out the solution if anyone else is ever interested in how I solved this problem.
Note 10+ N975U carrier universal and unlocked models firmware.
Yep. I'm going to download the files just in case ,but wait a few days to see if anything happens.I'm curious if that was your issue all this time .

Odin Files/Guides For S21
Flashing S21 Ultra t-mobile branded to unlocked? Hi Everyone, I am a new samsung owner. I recently got s21 ultra t-mobile branded. It is now network unlocked. But i wanted to have a clean bloat free phone so wanted to have unlocked firmware. As i understand it, i need XAA G998-UA firmware...
forums.androidcentral.com
And I used this very kind user on Androidcentrals help. The context of my question is not needed but I basically asked if I was choosing the correct files.
"Yes use the firmware from frija , you will also need prince comsey patched Odin which download from XDA website, this will factory reset your device for first time , choose XAA as region with model number from unlocked version. (He is refering to the model number SM-N975U1) Put the device in download mode and make sure using a good cable and try 7zip to extract the firmware,odin,frija ...then after extract the the firmware you going take for files Cp/CSC,Bl,Ap and put in corresponding slots in odin and flash"

OEM Unlock ATT to XAA S20 FE

I feel like I've done a big door.
I work in a cell repair shop and we had an ATT unlocked S20 FE that came in and I liked it so I bought it.
Long story short. I did some reading that you can install the XAA software using patched Odin. This was essential because I'm on Tmobile and didnt get 5G on the ATT firmware.
Easy enough. The device now has 5G access on Tmobile, and identifies itself as SM-G781U1/DS in settings.
The issue I'm facing is now unlocking the bootloader. The XAA firmware doesn't have the option and I'm unable to flash back to ATT firmware without (auth) fail errors in Odin and 'Secure boot check fail: PIT' on download mode.
Here's what I've tried that's failed so far:
- show option using time/date change
- software updating (I do receive OTA)
- flashing stock ATT firmware
- flashing stock TMB firmware
- Fastboot oem unlock (command not found)
- fastboot getvar unlocked (unlocked: no)
I'm about out of ideas, could use some guidance on where to begin looking next, I really like the power of this phone and wanna see what custom roms bring.
Device stats:
Galaxy S20FE SM-G781U (with U1 XAA flash)
CSC: ATT
Build: G781U1UESAGWC7
Service provider info:
G781U1_OYM_TMB_13_0011
TMB/TMB/ATT
Android 13, One UI 5.1

To be honest the custom rom screne for this phone is not so great yet. I imagine once the official support ends we will be getting some well developed custom roms.
As for the bootloader unlock issue, try using smartswitch to restore stock firmware, or try changing only the CSC if the firmware is multi-csc, the oem unlock option might reapper.
What kind of patched odin did you use to flash the XAA firmware? stock odin should be able to flash it too. As far as i am aware north american samsung phones do not offer oem unlock. The option probably dissapeared for good. There was etoken but since you are on android 13 i imagine the exploits have been already patched. You're basically stuck on XAA now. You can try using samkey to change the csc but i doubt that even that can help you oem unlock it.

for some reason Samsung doesn't allow bootloader unlocks in the US anymore. if as a phone repair guy you have the means force older firmware onto the device then you could pay someone to get an unlock token on the DL from a contact of theirs.
downgrading isn't something we can do at all hence me mentioning you maybe having access to resources others don't.
if you could get it onto the very first firmware you'd have a chance, if you can't there's no chance.
