[Q] Flashing stock

Hello,
Firstly i searched the forum for a good answer but didn't find one. Sorry in advance if this question has been already answered and i didn't see the thread \ post.
I would like to change my firmware from 4.2.2 NB5 ORO CSC to 4.2.2 ND5 ( or the latest ) NEE CSC. Is that possbile via odin without changing my CSC ? I mean if i just flash it directly will it work ?
My phone is not rooted and i know that in order to change the CSC i have to rood it. My phone is also locked on my carrier, Orange.
Thank you and sorry if this is a repost of something similar.

You can flash the ROM without updating your CSC IF the AP file does not contain the CSC file. If the ROM does not specify in its name that it only includes XXX or YYY without any mention of CSC, then you're fine (Assuming you download from Sammobile). If it does say something related to CSC codes or there are 3 model numbers (different or not) on the file name, then it includes the CSC.
You don't need to root to change CSC. You need the Samsung dialer code + your IMEI number, which will factory reset your phone but change your CSC.

This is the ROM i wanted to flash. I'm not quite sure if it includes or not what you said. It should be NEE CSC so i think i can't flash it...right ? :-s
If i can't flash it, can you give me a link to an example firmware that i can flash, other than my stock ORO CSC rom ?
The dialer code + IMEI doesn't work for me. I tried * # 272 *IMEI # and it says the code is invalid. Maybe because i'm branded on Orange ?

That is a full ROM. It includes everything - AP, CP and CSC.
I don't understand, do you just want to get rid of your ORO CSC ROM? You should be able to install your NEE ROM perfectly fine.

Yes, i want to fully get rid of this ROM because updates on this CSC are so friggin slow it's driving me mad. I want to completly move to NEE ROM. So i can flash this ROM perfectly with the instructions on Sammobile in the link right ?

You'll have to unlock your phone first on a website, then you're free to install any ROM from any country. If not it will still be locked to Orange.

No problem about that, i am still gonna be on Orange anyway. I don't want to unlock it just want to get a different ROM with a newer build number so i can (probably) get away from this stupid battery drain.

Give it a go, if you can't get it to work, just reflash your stock Orange.
The absolute worst thing that could happen is that KNOX would go 0x1, but you will still get your updates. If that happens, you should really just use custom ROMs, they're wonderful and updates more often.

I know about custom ROMs and i've been looking and them and i really wish i would have the gut to just screw my warranty but i can't do it just now. I've had some problems with my old Xperia Z and i'm lucky i had custom roms but on locked BL so i could claim my warranty. I can't even root it and it's just killing me but meh...
okay, i'll give it a go thanks for the advice and time spent answering to me ! Cheers !

I don't know how to answer your question but let me ask you... What is CSC and why you don't wanna change it ?

CSC is your region\carrier customization. It dictates what your updates are , what they contains and when you get them . I want to change it but i know ( i might be wrong about this ) that it's only possible via rooting, wich i can't do atm

OK so i flashed the NEE straight on my NB4 ORO firmware and it worked flawlessly.
So for everybody that is asking this: you can flash any full ROM with any CSC on top of any other CSC . This is my experience and i hope it goes well with you ! Good luck !

CSC is Customer Sales Code. You want to change it when you want to debrand/debloat your phone by removing carrier-specific apps or update it to another carrier's update stream (to get a different carrier's upgrades). It also allows for you to get correct APN values if your carrier's auto assign doesn't work properly.
You don't need root to change it, you need Odin and the CSC package. You can use the Samsung code + IMEI as a last resort.

Good job man! But you have to be aware, I did some research before you did it. It does not apply to all devices. As the Russian ORO and Nordic Countries are the "same" region, I automatically assumed you bought your device in Europe, hence you won't be region locked out of your device. If you had a Hong Kong device you will have to take account for your storage difference (whether its 16GB or 32GB) as ROMs are usually for the 32GB PIT (bootloader), and any flashing of other region based ROMs COULD brick your device.

Nice find , thanks for pointing it out. I don't think I have a region lock, it didn't have any of the stickers that usually say it's region locked. But yea, my version is from Europe.
p.s. ORO is from Romania

I can only see SER and MGF CSC on sammobile . It doesn't matter anyway because it seems in the end it's ok to flash anything inside your region

ok. stay calm. That's the 1st rule
I believe I can't ask you to check your about device, since you are stuck at ODIN mode already.
From what you are saying you are on latest Germany firmware, if I'm not wrong it should be ND3 Kitkat.
Did you try to root using the correct file of CF-Autoroot ? I mean did you use the correct file for the Kitkat N9005 version ?
Since now you are left with no other choice, I suggest you to download the same firmware of ND3 - DBT version again (if you still want to stick with germany firmware).
But if you want the latest one, you can try Singapore XSP NE4 (I'm not sure, but some users reported the NE4 XSP is not so good in dealing with GPS).
It's up to your choice mate. But if you are worry too much, you can just grab the ND3 - DBT (I'm not sure the germany this one still need the .PIT file or not), or any other Europe firmwares (try not to grab the provider branded firmware)
You can find this on samfirmware.com
Once you get already, you can use ODIN v.3.0.9 to flash.
Let it boot... if you stuck at the N9005 logo, power it off (or take out battery for few secs and put it back), and then press vol up + home + power to go into stock recovery, and then choose factory reset and wipe cache, and then reboot.
Btw,
Reason why you are not able to flash the firmwares you are listed above, is because you are on Germany last built (ND3) with the ND bootloader. It is not possible for you to flash earlier firmware with earlier bootloader.
Hope you understand my long explanation
feel free to PM me if you need more help.
cheers.

[Q] does flashing a custom recovery can hard brick my phone?

so i want to flash twrp in my S5 sm-g9009d , but im not sure if my model is supported , as it only says klte in twrp page (which i dont know if that's my device type , nor can i find any info about it :/ )
so what's the worst that can happen ?

Hi, Rinyumi ,
No, but there is red alert for all flash
You are lonely responsible of your fone
the Best way in this case hardbrick
In my idea is to flash last officiel
firmware or (stock rom )of your country with Odin

Yeah are included, you have to extract the zip, remove the .md5 and extract again, and use only system.img... search you will find how to make flasheable by odin again

ok thank you so much , ill look for it

Can i flash my samsung s10 plus with different region stock os using odin without bre

I bought my mobile from UAE and am using it in india. When i compare my s10 plus with s10 indian variant , s10 front camera quality far beter than my s10 plus.so i m planning to flash indian region os using odin and have some doubt on this. Please some one clear my doubts
1. Will knox service get tripped, if i flash indian os using odin.?
2. Is this issue occurs due to different region os or hardware fault
3. If knox gets tripped, will it be fixed later ?
Thanks

Anyone please respond my question..am getting different answer from different tech sites. Some people are saying flash different region rom will affect the knox. Some of us telling, it wont. Please confirm it.

Yes you will get OTA after flashing a stock firmware using Odin
Use the main CSC file (not the HOME-CSC) if changing region
I always enable OEM Unlock in developer options before attempting to change CSC with Odin (disable OEM Unlock again after you have completed flash to enable full security)
You can only flash a firmware file that matches your model Variant
E.g. you cannot flash 975F firmware to an 975U model etc
Finally be aware your phone will be wiped after the flash completes so backup everything before you start. Good luck

Thanks a lot for your reply. And i am not get your points about CSC...can you please explain little more

Firmware for Odin flash contains 2 CSC files. The HOME_CSC file will NOT erase your device, the CSC one will. However as you are changing CSC code it is best to use the normal CSC file and allow your device data to be erased as it’s not a good idea to mix data and settings between different firmware
Hope this helps and good luck

Thanks for your reply

Firmware change on S7 edge.

Hello everyone. I'm new here. I wanted to know if I can change my S7 edge (exynos) sm-g935fd firmware from UAE to India. I am currently on Oreo G935FXXS8ETCA Xsg which has bootloader 8 if I'm not wrong, but I want to install ins firmware G935FODD7ETA1 also Oreo which has bootloader 7 . Is this switch possible?
P.s. I want to change firmware bcoz I am not getting volte on my phone. I've tried a few things without any luck. And the only solution seems to be to change my CSC. Any help will be appreciated.

As far as I know you can't downgrade due to antirollback protection. I don't imagine switching firmwares would work very well at all

It not a rollback technically it's more of a sideways move but I might be wrong. Is it because of the older bootloader on the firmware I want to switch to?
Thanks for the reply.

If you attempt to switch your bootloader to an older version it can cause a hard brick putting the device into EDL mode but I do believe you can switch the system a bit

So there is no way to change the firmware? Is there any way I can get volte

You should be able to swap the system partition and CSC to something else as long as your not in any kind of Android Verified Boot

I don't know what that is. But I've only been using stock ROMs from ota updates. My phone isn't rooted either. I just want to activate volte on my phone. I would really appreciate if you could help me.
Btw thanks for the prompt replies.

You're absolutely welcome! I'll have a search around Google and maybe point you into the right direction. I'm sure there is a flashable firmware for Odin (combo-firmware) that enables this
EDIT:
Because your on an International chipset (Exynos) you can actually flash a custom OS which supports the Volte. Just ensure you've taken the steps to unlock the bootloader through the developer options in settings (enable OEM unlock)

Don't unlock your bootloader and dont root your phone
if something goes wrong the EFS patition will corrupt and you are on U8
U7 combination firmware is not available and we dont know when will it will be available
you have to download U8 rom and flash home csc from U7 INS (latest software available for India)
it will enable Volte on your phone
make sure to tick nand erase when flashing Autoboot and f.reset time

Unlocking and root have nothing to do with the EFS partition. Sounds like you may have did something like modifying it and caused data to be corrupt and you never kept a backup.

once i root my device then after monts i decided to go back on stock
then after some monts i decided to try NFE 9.0 Black Diamond after that i get many errors and made a mistake
6 monts before i didn't know things now i know things like bl and opening and booting phone wihtout bl and many more
its the easiest method to get INS VOLTE on UAE Exynos Model
My phone is running smooth but efs is corrupted that makes S/N No. none and no network
Phone is dead from march
Lets hope for U7 and U8 combination firmware

Thanks for the help. Really
Volte used to work before the Oreo update. And won't a custom ROM trip my Knox? (I use secure folder). I recently tried to flash a stock ROM with modified CSC file to get volte working on my S6 g920f. But it didn't work. It tripped my Knox and now my short codes don't work and CSC shows blank. Calls work though. But no volte.

You can wait for the INDIAN U8 STock and then flash it on your device with Home CSC which will surely enable volte
Remember With Nanderase f.reset time and auto reboot
Don't trip your knox i regret it!!

I would wait too if you trip Knox with a warranty then your SOL. If your lucky you won't be it's best to wait for the firmware

Well I am waiting till there is a stock firmware. But I don't think there will be an official update seeing as it's an old model phone and the official software support is only 2 or 3 years from the company. So fingers crossed. I might flash the ins version and try to make it work if I get a new phone and my S7 will become a spare.

And thanks for the help guys ?.
Now I'm thinking of flashing a custom ROM on my S6. Let's see ....
