No. You root only once. Then you will not get OTA updates. You can flash new updates via ODIN and keep the root.
But a friendly advice: If you're having to ask these kind of questions, I'd recommend going through the forum very carefully and understanding exactly how the rooting, flashing and update process works on Samsung, and what are the irreversible changes you will face once rooted, before trying anything you might regret later.

You can flash the new firmware via ODIN. Don't use the CSC file. Use the HOME_CSC file. The CSC will perform a factory reset, but using the HOME_CSC will keep your files and settings intact and only uprgrade the firmware. The AP, BL and CP files are common - you only have to be careful to choose HOME_CSC instead of CSC if you want to preserve your files and settings.

[Q] Question on firmware updates and ROOT for my new SGN

Hi!
First of all, I thank you all devs doin so much work on these forums, I am going to donate to most of you developing for my phone. I am new to Android (coming from symbian, FINALLY!!). Maybe this helps, I used to read these forums regarding flashing, ROMs, MODs, etc, it didn't make sense till I purchased this SGN. I have little knowledge. So...
I've installed Titanium Back-up Pro (yes I payed for it) then this asked for root access, then I installed/flashed this kernel with root, CWM, Super User and other stuff.
Everything seems fine so far, Titanium says it's ok, I back-ed up all stuff with it.
My questions are:
1. I want to know if this change will remove completely my Samsung warranty? (the author of the modified kernel says that Samsung can track changes done to the sys files like kernel)
2. If Yes, this also mean I cannot update the firmware via Kies anymore?
3. Is there any possibility that the kernel I use to get updated? Does this mean it could conflict with some new firmware version (If I manage to get it updated)?
4. If I update the firmware (if possible considering existing situation), will this put back the original kernel? Is there any side effect?
Please take a minute to understand my concerns. I payed quite some $$.

1.Rooting voids the warranty, but good thing, flashing back to stock, you regains warranty.
2.You can update via kies (If your currant firmware same as it shud be for your country, b'coz if you manually update newer firmware, which was not released over kies in your country, Kies wont recognise and so you cant update) but, You will lose Root + CWM
3.Usually you will get newer kernel according to your firmware from thread you have used early. But to be practical almost newer near release kernel works for others. e.g. I am using CF Root KL7 for LA4
4.It depends on the way you are updating, If tou update over Kies OR with PC Odin, it will replace with original Kernel. Too keep Rooted n preserve CF root Kernel, you have to use Mobile Odin/ CWM to update firmware.
You may get details of updating newer firmware here

Excellent!
Thanks for your quick reply!
Sounds like you have the freedom to do all around upside down: go "illegal", go back to legal, but there seem to be more for me to understand:
Ok, suppose I proceed with update via Kies, I loose ROOT and CWM. Then, if I want to put back the root and the CWM, I need to find one compatible and it's not going to be for the same KKA I have right?
1. If your device is rooted then the their is so warranty.
2. Yes.. you will not get updates from Kies. (if you are rooted)
3. You can flash Official ROM and Kernel via PC Odin. (Warranty Revoke)
4. you have to flash Official PDA, PHONE, CSC Via Odin PC.
Then you ll get complete Official warranty. Be careful while flashing. Read everything.
Follow this thread for more details about flashing and follow the instructions.

Doc u too fast..
I don't fully understand this new language, it's a bit confusing.
Anyway, I am now trying to connect Kies and it does not allow it initiated from computer, but from the phone itself, via browser.

If you are rooted the device then you cant update from Kies. Just forget about kies.
if you want update device, download Firmware from above mentioned thread and extract it.
you should get 3 files.
Download Odin from the same thread.
Open Odin Attach those 3 files as mentioned in thread.
(i.e : PDA= CODE_xxx , PHONE: MODEM_xxx, CSC: CSC_xxx)
UnTick Re-Partition and leave Auto Reset and F.Reset time ticked.
1. turn off your device .
2. Put device in download mode by pressing Volume Down + Home + Power hold it for 3 - 5 seconds.
3. Device will prompt you to press volume up to continue and volume down to cancel. just press volume up then you can see Downloading mode screen.
4. Connect your data cable to device and PC.
now you can see yellow colored block on Odin and shows "Device Added".
5. Click start. Thats it wait until it restarts.
Thanks again, excellent!

Ok now I understand there is a new update XXKKA but it's not available for Mobiles in my country, but it's available in Germany (everytime they have it first).
I will purchase a MicroSD in the next couple of days and back-up my apps and user data, then I will try to flash this latest firmware XXLA4.
I hope I can upgrade firmware with CWM so I can keep my data, my accounts, my apps and settings.
My question is now, my firmware now is XXKKA (my phone says it's the latest), is there any conflict with this latest XXLA4 or maybe kernel issue? I don't know much about these, I am just concerned.

Here one think you should notice that LA4 is an official update for only some regions. it means if the LA4 dint released in your region , Kies wont Support LA4 too even it is an Official.
I suggest you to update to LA3 , any way ICS will be releasing soon for our Note. and Don't bother about Kies update. more over in this ROM you ll get warranty too.
Thanks again man, I guess you will be assisting me at that time

Unable to update Galaxy Note N7000

Hello,
I'm currently living in Chile and apparently Chile released the version 4.0.4. I tried updating my android version through kies and the phone updater and no luck :/ My phone is rooted and the kernel is [email protected]#2. I'm not sure if the inability to update is due to the fact I used a kernel from another country other than Chile (I think I used an Indian Kernel). Is there a way I can go back to the my original kernel and unroot to update normally? I also have the urge to unroot my phone since my music player has been crashing too often and feel that the problem originates from the rooting.
Note: I am a very new user and I don't know most, if not all, terms such as flashing.
Help is very much appreciated,
-Kathy
Why don't you directly update it from here ---> http://forum.xda-developers.com/showthread.php?t=1424997

When I flash my phone do I need a Pit file? Will this wipe all my music, apps, contacts, etc...? If I use a original chilean rom then my phone will be unrooted right?
Sorry for asking so many questions >.<

You don't need PIT files. Just Select rom file under PDA tab. No need to change any option. Just Start Flash.
And it will not erase your data on sdcard (internal or external)
Cheers
You need to backup your contacts,msgs and apps
Hope I am not to late, would be best to make efs backup before proceding, so you can always return to chili working rom. Its a backup of e.g. imei which is not easy to recover if accidentally lost.
How see toolbox thread dr ketan in general section. You need root for that. Save in multiple locations

You cannot update to lollipop using twrp.
It has to be done using odin.
If you want to stay 100% stock and rooted then you need
to odin flash twrp and cf-autoroot.
If you want to flash a custom lollipop rom then you will
need to odin flash lollipop official firmware and odin
flash twrp.
All custom roms are pre-rooted so no need to root them.
Good luck!

Thanks.. So can I just straight up update from what I'm on now?
Just put phone in download mode and update via Odin correct?
Will this erase my stuff internal memory? Movies/pictures
Yes you can. You should back up your stuff though because you'll want to do a factory reset or erase data to get the best results with lollipop.
Although, I did all that and I've got my movies and pictures.

Be sure you get the proper version of the lollipop N910T tmobile
firmware from a reliable source like http://sammobile.com and
flash it using odin.
Before flashing new firmware it's always best to do a factory reset first.
Back up all your important stuff first.
Good luck!

OK thanks.. OK I finally have time to flash. And update... So it's ok and safe to factory rest on my custom ROM im on right now?
factory rest /put phone on download mode and update by Odin on my computer correct?
Sure is a big file to download :silly:
That's totally safe.
I just odin flashed.
I didn't erase data till I flashed my rom.
Admittedly within a minute of going through the process.
Mega's instructions are good. You just stop at 5
odin reads and i get the com light up and reads it but it wont find my lollipop firmware i downloaded on the pda part

You need to navigate in odin and find the location where you saved the firmware file.
There is a box next to the PDA slot and you need to click it and use it to locate the file.
Good luck!

Yes it's perfectly safe and doing it that way you will not loose any data,
passwords or settings.
It also is a lot faster than downloading the firmware file.
I am not sure if rooting makes a difference, when I updated using kies
it worked fine for me, kies did tell me that I have un-official firmware
but it gave me the option to continue which I did without any issues.
With kies it takes less than 1/2 the time for it to complete the download and
install/update the firmware compared to a standard download and flash..
Good luck!

New android user needing assistance

Hello I've recently moved from iphones to my first Samsung. A Galaxy S10 which I bought off the internet.
The instruction booklet that came with it was in foreign which I didnt think anything of as it accepted my sim card and everything seemed to be working ok. However when i came to set up samsung pay I realised the phone was set up for the united arab emirates, which samsung pay wants me to register to.
Can I reflash the phone to a Uk rom, or am I stuck with the phone as it is? If I can reflash is it done using Smart Switch?
Thanks in advance for any help
You can reflash the stock rom you're on, yes. Try a data factory reset first in recovery.

Thanks, I'll try a factory reset first. Can I just ask a couple of questions in case it doesn't work so I don't end up with a paperweight. I've jailbroken iphones in the past, but never owned an Android, so I don't know what I can/cant do.
1) I'm on O2. I assume its firmware G973FXXS7CTG1 I need. Will the CSC be correct after the reflash? From what I can make out from other posts, if I reflash with my simcard inserted, this will change automatically.
2) Will the reflash trigger Knox? As far as I know the phone is unrooted currently and I'd rather keep it intact if possible.
3) Will I still receive OTA updates, or will I need to do them manually?
4) Is the reflash done through Odin not SmartSwitch?
5) My Smartswitch backup will be restorable after the firmware change? (It's not backed up for one specific firmware only)
Thanks

1: Get Frija to d/l your firmware as it is the fastest way to d/l. Input your model no. and CSC (in your case: O2U), check Auto and Frija will give you the latest firmware for O2. Never heard ones simcard should have any influence when flashing???
2: No. Knox is only triggered if you flash TWRP/ custom ROM/ Magisk aka root your phone. It is completely safe to flash stock ROM using Odin.
3: Not sure - am rooted myself. My experience upgrading via Odin is safe/fast/reliable.
4: Odin. Most important: use HOME_CSC in the CSC-slot. This will keep/restore all your data/apps.
5: Never used Smartswitch???
Cheers. I had a trial run using my galaxy tab a. All went well so going to do my phone next. Thanks for the help.
Update:
Tried my phone but something's not working. I've extracted the firmware from Frija, selected home_csc as well as the ap,bl and cp.
The flash starts, but for some reason though after about 3 seconds I get Odin saying Pass, the phone restarts and nothing seems to have changed on the phone.
Any ideas what I'm doing wrong? The phone was in download mode

Question Looking for a Flash Guide S21 Ultra

I just downloaded a new firmware from Sammobile, but I don't remember what to do now.
I have a custom rom flashed right now, as well as Magisk, so I'm not sure if the procedure is different from a new/clean phone.

Then you need to extract the AP section of the firmware, copy it to your phone. Then open magisk and patch the AP file, then copy the patched file back to your PC. Then you can flash the firmware in Odin using the patched ap, with the bl, and the CSC home file. If you use CSC HOME then your data will be kept.
Great! Could you explain the steps in more details?
