Modify Stock Odin firmware? - Samsung Galaxy Note 8 Questions and Answers

I was wondering if it was possible to unpack the stock AP file, remove bloatware and then repack it. Although, I'm not so sure if this is possible since I haven't seen anyone try this? Im just curios.

Yes you can but you won't be able to flash it with Odin anymore. There's a reason why you haven't seen it done. If it were that easy we wouldn't have a need for unlocked bootloaders, root access, & custom recoveries.

[Q] Still have supercurio's kernel after doing a disable lagfix

Hi,
I recently disabled supercurio's voodoo lagfix on my Bell's I9000M with success (ie. everything's back under rfs). However, I still have his kernel on my machine. How do I revert back to the standard, stock kernel?
I'm quite new to the whole business of Android firmware "hacking".
You will have to flash the stock (JH2) kernal, but I do not know where to find the stock kernal. Maybe someone can provide a link to it.

It is my understanding too. I guess an update.zip with the proper kernel would be all the I would require and it wouldn't erase my system.
You can flash some of the custom kernals others have made into a update.zip. But if you want the original JH2 kernal, You will probably have to flash the whole ROM via Odin. I have not seen the original kernal in update.zip format, maybe someone else might get us a link to it. I would also like to get rid of Voodoo on my phone and go back to stock. I'm affraid of losing my internal SD.

How do I flash with Odin the original JH2? Can I extract the required files from the Kies install directories? I don't mind reflashing everything.

If you are gonna flash it all...you might as well just flash the latest 2.1 which is JM8. The "how to's" can be found here: http://forum.xda-developers.com/showthread.php?t=723596 but I do not see where to download JH2 or JM8.

I got the I900UGJH2.rar file and I'm currently flashing it with Odin. Wish me luck! First time doing that kind of thing.
Let me know how it goes and where you got the file. I will be doing this soon also.
Also, I think you have to repartition with 512 pit to get rid of the Voodoo. I dont know if uninstalling Voodoo with disable folder/file gets rid of th ext4 completely.

Quick way to flash stock rom and root it?

I keep keep switching between roms and having the stock rom seems to be the mid point. So was wondering if there is a way to flash stock rom (latest) and root it. Like in samsung i use to flash the stock rom via Mobile odin and that app had the ability to root while flashing..do we have any similar way to do it?

No. ..and do not even bother your self to ask more question about it, there is no way around, the only way is the one which you already know, like in my signature.
keep a backup on your sdcard and just restore it, no need to flash stock, downgrade, install recovery, install pre rooted rom.
Once you have root and recovery, just restore backups....

NJ3 to NJ7

I have a Canadian N4(910W8)and I want to change the baseband so I can try different Roms. How do I go about this? I'm guessing through Odin right? Where can I find a stock NJ7 ROM to do this? Thanks guys!

Firstly, if you change baseband your phone will not work with Canadian or
USA roms.
None of the twrp flashable zip file roms contains the baseband or bootloaders.
You need to keep the Canadian baseband which you already have.
What you will need to do is to save your kernel file so you can use it with the
USA zip file roms.
The kernel is located in the /System/ folder and the filename is "boot.img".
Copy that file to your internal sdcard before you do anything else.
Then after you download a usa zip file rom open it up with winrar/winzip
or other archiver and remove the boot.img in the zip file and replace it with
the boot.img you have saved in your internal sdcard before flashing.
Once you do that you can safely flash the usa zip file rom of your choice.
I never advise anyone to use a different carriers rom, there are many con's
against doing so and not many pro's. But go ahead and give it a try.
Good luck!
Thanks for the helpful info! On my note3, I always flashed tmob roms with no issues, but the note 4 is new so I didn't know exactly what would work or not. Might give this a go later on! Thanks again!
I find sys>kernel>boot_adsp> the file called "boot" which is only 4kb in size. Is that what I'm looking for? Does not have "IMG" behind the "boot"
Hi.... I was wondering the same about the NJ7.... I've flashed 2 TMobile roms so far... Darthstocker & Hyperdrive.... As long as you flash the Starkissed Kernel it boots up fine... Without it you just Bootloop....

Downgrading using Odin to lower binary

I am currently on G780FXXU8DVC8 firmware and I want to flash G780FXXS7CUI5
I know that right now the binary no is 8 and the firmware I want to install has binary 7.
Can anyone tell me if it is possible to do so using Odin? As i've heard one can't go to a lower binary using Odin.
Is there a way to go to a lower binary?
it's not possible via Odin, technically it probably is still possible with a lot of work modifying the firmware. obviously it wouldn't count as official firmware, and no I don't know how.

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.

Depends if you want to keep the phone rooted or if you want to return to stock
I wish to keep it rooted, as well as to keep my data (if possible).

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?
