Update a rooted device with odin without wipe data - Samsung C9 Pro Questions & Answers

Hi Guys
I want to update my c9 pro with Odin (home_csc) from nougat to oreo.
the problem is my phone already rooted and I dont know what happen when I update it with odin.(boot loop or ...)
i know i can backup my data and flash it with normal csc but i dont want to wipe my data.(app data).
what can i do ?

You can update it with home_csc without loosing your files if you are still on stock rooted rom. If you are in custom rom you will loose everything. You can go ahead and update it with odin without any fears.

[Q] what is currently the best way to root i9505?

Hi, i am in the uk and had my i9505 for around 2 weeks, just wondering the best way to now root and is there anyway which is the safest / recommended?
also, can rom's still be updated afterwards via ota or kies if i root, i know i would have to root again but would my phone still be supported by kies and look for new fw's after rooting?
thanks
james
Personally, I use the pre-rooted stock roms in the Android Development section:
http://forum.xda-developers.com/showthread.php?t=2250824
Very easy to use, just download and flash via Odin3. There may be easier ways, but for me this is the easiest.
All you need to do then is flash custom recovery and you're done.
Edit: Not sure about Kies, but it's easy enough to flash back to a stock rom and then reset your phone to Official again.
Some custom roms offer OTA updates, but personally, I prefer just staying on a stock rooted and update via Odin as and when needed
Thanks for the reply, if I flash the pre rooted Rom will it wipe my phone or will settings and apps still be the same afterwards?

If you install pre rooted rom, all your apps, settings etc will remain. Odin3 doesn't touch the data partition, so you'll still have everything.
I usually clear cache/data after installing a new rom, so I start from fresh, but it's really upto you really
One thing to be aware of though is that flashing a pre-rooted rom will clear your custom recovery, so you'll have to reflash recovery after installing an updated pre-rooted rom

Question about Odin

I want to root my N910F but there is one thing i need to know before i do this, i dont want to flash a custom rom, just stock rom with root acces.
I know something about rooting and flashing from my other phones.
What happens if i root my Note4, and samsung rolls out an update.
I know i wont get OTA's, but what happens if i download the update from sammobile, and i flash it via Odin, will i loose my files and settings everytime i get an update ?
Or is there an option to just "Update" the stock rom ?

If you flash a rom from sam mobile via Odin it will do a factory reset on your phone(data not internal).Depending from your options that you enable in Odin it could and could not delete your internal storage...and no in Odin there is not such thing as...update unfortunately something like that is only achievable with a custom recovery and flashing but not all the the time if a rom is very much different from another or their base is different a data wipe is a must.
In my experience flashing a basic update over your current rom will work if it was stock to begin with. Root will be removed when you do this. I would not recommend doing this as you could cause problems down the road. I would really not do it for major OS changes like KK to LP. Whenever I flash, I backup what I need to keep, full wipe with custom recovery, then flash and restore data. As mentioned you can't really update from Odin.
Just root the phone that's the reason u came to XDA if Samsung pushes out update it will be available for download on here

If you want to keep your data you can use odin mobile from chainfire without tick any wape options but remember to chose supersu and odin injection after flash.
I'm not sure if this will be without issues because the baseband its different.
Remember to make a backup before any steps!!!

Stock ROM Backup

Hi,
I have rooted and installed TWRP on my 910F Note4 as I was fed up waiting on the lollipop update rolling out. I am currently on 4.4.4 and have made a full backup using TWRP of the stock rom.
My intention was flashing the Cyanogen ROM and using that, but i now see on sammobile there is a stock 5.01 rom available. I have a few questions about this.
1. If I flash to Cyanogen can I still revert back to the stock rom 4.4.4 I have made a backup with? I read somewhere there might be problems as I was on KitKat then moved to lollipop(Cyanogen).
2. Can I flash the stock lollipop rom from within TWRP? Or do you have to do this via ODIN?
3. If I flash the Lollipop stock ROM with Odin I assume I will lose root and TWRP? So this would have to done again?
Guess I am asking what is the best way to proceed?
Thanks again
Paul

hi Paul,
1. i beleve to flash CM from kitkat you will need to install the lollipop bootloader first.
2. You have to flash the stock rom via Odin, you will keep all apps settings and files but you will lose root (you u can re root in 3 minutes)
Best thing you could do is flash the stock rom first with odin, see how that feels (IMO its good been using it for months now) and then root it and back it up and flash CM12 (you dont have to flash any boatloader at this point)

Ok tried to flash Stock O2 UK lollipop ROM via ODIN and got error message on screen. MD5 too big or something. Had to pull battery on phone. Had to then reflash TWRP. Got back into TWRP and tried to do a recovery of the backup I took but phone is stuck at Galaxy note 4 screen. It then shuts down and restarts and gets to the same screen again.
Do I try a different ROM? What can I do?
Thanks

I got it working by flashing the German non branded ROM... Got the error message again but then used a "All samsung recovery.tar" as stated on another post in here and it booted fine eventually... Now on Lollipop. Now time to flash with TWRP.... Again!!!
Please, i need help !
I need help, urgently !
My Note 4 SM-N910C does not work. I can enter the Recovery and the Download Mode. When attempting to install a Custom ROM gives me an error that says I have no data. In the internal memory I have 0mb.
I tried using odin, but I can not .. Salta error.
Someone who can make a backup of your phone (which is factory), leave me a link to download it? So I install the TWRP. Please.
They have another solution?
Thank you.:good:

Downgrading from CM 14 Nougat to stock TW 5.0 lollipop???

Sorry if I'm posting in wrong section actually I'm a newbie
Hi all, I've updated my Note 3 SM-N900 to Cm 14 nougat 7.1.1 unofficial lonage os by ha_3g. Now i want to go back to my stock Twiz 5.0 lollipop, is it possible I've all my rom backedup by TWRP. Can i restore my backup without any problem?
Thanks in advance
nah,usually i just flash my firmware using odin without backup
Usually if you want to revert back to stock firmware, everything will be removed, including your custom recover(TWRP in this case), miscellaneous files and folders that were previously on your custom ROM. So, in summary, you won't be able to recover your backed up apps/data as TWRP will get wiped out as well, being replaced by the stock Samsung recovery.
Yep, wipe system, data, cache & dalvik then restore your backup.
Before updating I've backed up my stock Twiz rom via TWRP, now i just want to revert back to my Stock rom which was lollipop 5.0. I'm afraid bcz I've seen some where that we cannot install 5.0 (lower version) over 7.1 (greater) version it will brick the phone bcz of some bootloader issues, btw I've not messed up with bootloader, so plz advise me if it will be safe or not.
Lot of Thanks for the members of the forum who replied in no time & who r ready to help. Salute to all of u. you people r great
Only a stock firmware flashed with Odin can upgrade your bootloader.
And the latest official firmware for Note 3 is Lollipop 5.0.
So your bootloader still 5.0 even if you flashed a nougat rom.
Even more, custom roms don't touch bootloader or modem partitions, ever.
Go ahead
Hey bro. Just go to sammobile.com and download your rom and flash via Odin. Only Odin can downgrade your BL and Modem
Thanks alot for the clarification I'll go ahead now.
I can swap between 7.1 Nougat and 5.0 stock, with no issues, through my nandroids.
If you had a nandroid before, you shouldn't have any issue just using the TWRP function to restore your backup. It will be exactly as you had it before.
The only difference will be that you will still have TWRP installed, etc.
Anyways, you can swap back and forth as much as you like. You don't have to wipe anything, or use Odin, since you made a nandroid already.
Yes you can go back to lollipop . I have done that in my sm 900 exynos version. marshmallow and nougat drains battery
