[Q] Can I flash a stock firmware for a different region other than my original stock

First, thank you guys. Just bought a note 8 WiFi version GT-5110. It is a good device, loved it. I've been researching and reading all over the posts about rooting, install custom rom, firmware and etc... I guess the first thing to do is to root my note 8. So, before I root my device I want to know for sure I can return back to original unmodified stock. I found that I can use ODIN to flush official firmware. However, I checked samMobile for the firmware for my country which is Canada. But I couldn't find. I used toolkit to check my note 8 firmware. It is N5110XXBMC9 and the region is XAC. It is the oldest. Hate it, we are so close to the us but always treated differently, and very thing is more expensive.
Question:
1 Can I just flash US region firmware? Since I have the WiFi, it has nothing to do with the phone and carrier. Or, can someone tried to flush a different region firmware tell me what is the outcome.
2 If I flash an US firmware, will I still able to claim warranty in Canada(just in case).
3 Will Flushing firmware with ODIN increase flush count, even I flush with official stock?
4 Last question, after rooting, will note 8 achieve floating multiwindow like note 10. Or, we are still limited to have to window side by side, but with rooting, we can put more apps to choose.
I know you guys are busy, if anyone can help me or point a useful post for me I would be really appreciated.

I would also like to know the answer to this question as I have a New Zealand international model but the rom is old. Can I flash the UK version which is the most uptodate. (I have the wifi version).
Thanks

I decided to give it a try myself.
I flashed the latest BTU N5110XXBMF2 which worked a treat. I checked and this is what is displayed
Custom Binary Download = No
Current Binary = Samsung Official
System Status = Official
So it worked fine for me.

Hello. I am also having this issue, with a GT-N5110 from canada. May I ask the steps in which you flashed the firmware? Did you do it via Odin?

I just downloaded the firmware and used Odin. It didn't wipe the sdcard it just updated the apps. Its worked well ever since.
I have since updated to N5110XXCMK1 using the same method.
Regards
Colin

Thanks. I used the same method to flash 4.2.2 on my device. I am also now on xxcmk1.

flash counter
Hi guys! I was looking to know about this. And I got a few question:
1. I want to make sure about the flash counter. If I change to XXCMK1 my rom, the flash counter goes to 1, or would be like the note 8.0 came with that stock room (nothing change in the counter)?
2. It is a little off of the main question but I will ask anyway: have you tried to add icloud email to the native email manager in the XXCMK1 rom? (Asking just in case you did it, since I read that rom is the one that doesnt have problem to set up in the native email manager?
Thank you guys (literally). I will appreciate your answers.

1. My flash counter did not change when I flashed 4.2.2 using Odin.
But it did when I used auto cf root afterwards to root the phone.
2. Nope I haven't tried.

I had an issue where I (think) I soft-bricked my device, as I could not get it to boot up, it would get stuck on the "samsung" logo and then display a black screen and go no further. My device is Canadian as well, and was running stock Canadian firmware, but I had rooted it before hand and was attempting to flash firmware from another country.
Well, I ended up downloading the US firmware for 4.2.2 from another thread here on XDA and flashed that in a last attempt to fix it, and it worked! But now I'm running US firmware. Since the KitKat update is now available in Canada, I'm downloading that as we speak and am going to flash it when it's done.

Update: flashing went great, just had to remove the .md5 at the end of the ROM file. Everything seems to be in order.

Definitely more info needed.
What ROM is on your device?
What bootloader did you install?
What modem/baseband/radio is on your device?
What method did you use to try to install the bootloader?
Is your phone still showing the correct IMEI in settings or 0 ? (Compare between that shown in settings and under the battery.)
It may be as simple as updating your modem, but I/we can't tell yet.

I'm new at this, in fact I have flashed by old Captivate several times but yet to flash my SGS3. Anyhow, I have spent many hours reading. Before doing anything I suggest, read, and read some more.
Don't flash back to 4.1.1 or 4.1.2 at this point. They will install an older bootloader than is currently on your phone. From what I have read, you narrowly escaped bricking your phone. You might want to read some of the threads regarding the 4.3 stock ROM and unbricking before making any changes in restoring your device.
You can probably fix this by flashing the modem that goes with the 4.3 series ROMs. It would also be the MJB flavor, although the MJ2 would probably work. Several of the 4.3 TouchWiz ROMs in the development forum have download links for the MJB modem. I would guess you were probably going to install one of them. I would recommend flashing the modem to see if that solves your issues before going ahead with the ROM flash.

The reason I didn't put a link in the previous posts was to get you to read about what you were doing as you searched for the modem. I am offering advice on things I have yet to experience on this device and only speaking second hand. My advice is only based on what I have read not on anything I have had to correct myself.
In truth I think you just stopped too soon in the process of what you were doing earlier. You said you installed the 4.3 bootloader in preparation to installing a 4.3 or later ROM that required the up to date bootloader. You didn't mention installing the current modem/baseband. You didn't mention trying to flash whatever ROM you had been considering.
You may be able to correct your device simply by installing the 4.3 modem. HERE is the modem thread, it is in the General Forum for our device. Make sure you pick the correct one. I don't know if your device will work well on the MJB bootloader and modem with a 4.1.1 ROM, from something I seem to recall reading I suspect it will.
Take this in steps. Install the correct modem, the one that matches your bootloader. See if that corrects you sim, data, and IMEI problems. If it does correct the issues, the next step is to decide if you want to stay on the 4.1.1 ROM or change to whatever ROM you had been considering. If you decide to change, make backups first. If it doesn't fix the problem while on 4.1.1 you may want to flash the version of the official 4.3 ROM enewman17 has provided on the development thread.
Take it one step at a time. Read about what you are about to do until you understand it well, all before doing anything. Make backups sequentially as you make each corrective step.
HTH.

thanks man for telling me what was wrong your an amazing human being and i love you (no homo) and thanks again a million thanks bro.

Did that modem fix some of the problems?

If your on 4.1.1 shouldn't you flash the DKL3 version or can't you just flash thru Odin the DLK3 stock ROM thru Odin Amd start all over again
I've been on 4.3 with that bootloader Amd have flashed back to 4.1 back to the baseband version DLK3 firmware. I would think being on 4.1 you should be able to reflash using Odin to fix the issue or flash the modem for 4.1 .

Requesting 5.1.1 N910AUCU2DOI2 Odin AP file

Hi all,
I have tried all methods, factory reset, change to ATT sim(non-active sim), non of them work. I dont have an active ATT sim
I think the only way for me to upgrade to 5.1.1 is through Odin.

I'm waiting too

I've got the 5.1.1 update on my phone. And would be happy to provide odin files for it if someone can tell me how to pull it.

I have the same problem. My att note 4 is on Cricket wireless, and I haven't noticed any OTA when checking for updates. I've read on another post that att pulled the update and sent it back to fix the install issue some are having (among other issues). I really would like to try a manual Odin firmware update and see if it goes through... Please, if anyone could provide the files, that would be great. I'm tired of waiting with this annoying battery drainage issue with 5.0 - 5.01...

Just an FYI, I have a friend on Cricket. When Cricket was still using the old carrier (was it Verizon?), Cricket released its own updates. Usually a month or so after the main carrier.
That was when Cricket had its own phone models though. My friend had an S4 and it was a Cricket model number.

Yeah it failed for me to. I honestly don't know at this point. I'm not a dev. I know some things lol. I think there might be something wrong with the current firmware that is causing it to fail. This is the first I've seen this ever happen. I was trying to find the Odin files for 5.0.1 but I don't see them anywhere yet. That way we can odin flash current firmware again then try update. If that fails, we'll need to wait for the Odin files for 5.1.1.

Odin files for 5.1.1 will hopefully soon be up!

I 'll give the device to my wife and I will buy the note 5 of TMO . I think I'll have better opportunities.
thanks for your time my brother!
From what I 've seen the least bad brand is Samsung , because the other brands bring poor processors (MTK ) or are bad devices to develop OS cooked.

I tried this method and it works fine for me.

{Help} On 4.1.1 because of IMEI problem :(

I need help serious. My Note2 (7100) is stuck on 4.1.1
Here is story:

Recent i bought a N2. I was on 4.4 stock but don't know how my IMEI number got corrupted. So Samsung service center guy tried everything but failed(he was not skilled i guess) , at last he downgraded the phone to 4.1.1 and advised me not to upgrade it future.
But i want to taste custom RoM but i m still using ugly stock 4.1.1 which is so bad.
Please tell me whole procedure that i should follow to flash a Custom Rom ( like Eclipse or DN4 or anything ) and do not face IMEI corruption problem and please do remember that i m currently on 4.1.1 stock rooted.
Thanks

Well, if it was on 4.4.2 stock I doubt the downgrade to 4.1.1.
Check your bootloader version with Samsung info app from play store and let us know.

As expected - it is 4.4.2 KitKat so the attempt to "downgrade" has failed and yes, the rest of firmware is older.
It is kinda mixture and if it works for you I won't push you to change and update. There's always a little risk - I would take - and upgrade to newer kitkat for your region - get it from sammobile and flash through Odin, where are you from?

I m from India and yeah i found 4.4.2 stock for my region http://www.sammobile.com/firmwares/download/40791/N7100XXUFNL1_N7100ODDFNI1_INU/
And sorry my English is little weak. As you said it is mixture now. So is it risky to do anything with it? Also after upgrading to 4.4.2 via odin. Can i able flash custom roms? Or i better stick with stock 4.4.2?
Actually the reason why i want to upgrade is i get random reboot occasionally and 4.1.1 feel very odd since i have been on 4.4.2 earlier.

Whenever you modify your device there's still a little risk but nothing major.
This mixture you are running is definitively the reason for inconvenience - so go for a newer 4.4.2 and you'll be ready to enjoy custom roms you like.

Read this guide HERE and follow :highfive:

Installing the Official 6.0.1 update via Samsung Kies or Odin or different method.

Hey everyone.
I'm running on completely Stock 5.1.1 OK1 on my Note 4 and just recieved the official MM OTA update last night. Due to my phone having a lot of junk and being laggy I decided to flash the official firmware from any external method to have a clean install of the os. I heard about Samsung Kies which makes a back up of your phone and installs the latest os, I installed and backed up my phone last night but it didn't seem to give me an update on the os, it said "This is the latest version" (5.1.1 COK1).
My main concern about this is. I've bought this phone from Pakistan (used phone but in brand new condition) and I'm currently living in Malaysia and I have no idea who was the previous owner of this phone. In Kies it shows the phone number different than what I have (maybe its the Sprint phone number?).
What if my carrier is locked by having a clean install? Or any sort of other related issue occurs.
Please take some time to enlighten the facts from your knowledge, will highly appreciate it.

Yeah but you totally missed my question here.
Its not that I don't want to do some research myself, I'm a student and I'm busy most of the time. So if anyone can take out their precious time to answer my question I'd really appreciate the help.

If you're concerned about your phone or sim getting lock..you can just use galaxy tools apk v3.1.5 & then upgrade the apk to v3.1.8 & it will unlocked it for you... but i doubt it will lock you down... maybe you can just try to back your rom completely & restore if any issues encounter

it's dependent on the way that they unlocked the phone, someone in vietnam has been locked after updated the phone, but my phone was not.

And I have no idea how my phone was unlocked, I just bought it like this. I can see the Sprint phone number on Samsung Kies maybe I should write an email to Sprint asking them to unlock it using that Sprint phone number?
