If I wanted to upgrade to an upcoming version of Android released in whatever region got it first, how would I do to flash it through Odin without losing my region's Modem?
I know I could simply re-flash it after completing the newer rom installation, but I'd like to know if I could skip that step.
Thanks for any help.

With Mobile Odin, you can clear the modem section and keep the current modem during the flash.

Eh, if I need to root to use Mobile Odin then I'd rather wait until my warranty expires to do so, so I'd have to discard that option.
Thank you for the reply, though,
you can unroot at any time and regain warranty

After downgrade you have to do a wipe data/factory reset and then it work!!!

Well you can't access 3g because your apn details haven't been entered. Easy fix.
Flashing any firmware is the same process whether upgrading it downgrading. It not like an iPhone where you can't downgrade (without shsh blobs that is).

Yes, they are correct. i called the helpline last night to install the config settings but still cant connect.
I think i need a different modem (xxki4). is their a way to flash only the modem and save the downgrade process??

You can flash any modem you like without having to reflash firmware. You can flash zip versions in cwm recovery or tar versions in Odin, in the phone section.

hey there!!
so i have the SGP521, and i understood that if i want to root it i need to flash older version of the firmware, so as it. - i did it! i installed the 17.1.A.2.69 firmware, and i rooted it sucseccfuly! but now i want to update it's firmware to the latest, and i don't know if it possible, that i will flash a new firmware and keep my device ROOTED. (i'm using Flashtool).
is there a way to only "update" the firmware without wiping the root (and maybe without wiping the user data too..)
thanks!

Having read these three threads, I don't know and it seems the 511 trick works for the 512. Don't know if it will do the 521.
I'd like to know of the lollipop update coming will be rootable or kill root.

I think I will not take the chance and maybe lose my 4g LTE contectivity by installing other version firmware..
But i will wait for the lollipop update too (hope it will not kill the battery, like it does on almost every phone it's installed on)
but thanks very much for the help!!
Hey Guys.
Once i tried to downgrade my Galaxy S6 Edge SM-G925F from Marshmallow to Lollipop with odin, but it failed and i had a brick. I tried different Versions of Odin and with much luck i fixed my Phone. But now i am insecure and hope to get help from you. I installed latest Smart Switch Version. What do i have to do to downgrade without bricking my Device?

Only possible when flashing 5.1.1 custom rom via recovery, but you will lose your imei, BUT you can backup your imei and after flashing new rom restore it.

Yes before you proceed you will need to install a "custom recovery" (Search about it if you dont know what it is)
Go to recovery like you want to format but instead go to "Backup & Restore" and select backup and then select "efs" which is IMEI.
After flashing a custom rom and after the first boot you will notice that there is no signal, so go to recovery and select to restore efs.
I recommend you to backup efs to ext sd card.
This will void your warranty, even downgrading it self will void it.
Goodluck!

Any firmware 4DPG1 or above can not be downgraded. Im guessing before you was on U3DPAD or lower which can be downgraded. The first MM builds could be downgraded. But any 4xxxx can not
ah ok....
then i downgraded fast enough
my main reason of downgrade:
in MM it is not possible to change the font with HiFont App....!!!
i see other people saying that it's possible.
but i have one of the latest builds so, in your opinion , it is impossible for me to downgrade.
but are you sure? i can't believe that, i want absolutely a solution, i am searching it from so many time, please help

What build number are you in? It is impossible to downgrade from a late build 4xxxx. I have tried absolutely everything. The only way is to flash a nandroid backup but even then you will lose imei. You can always back up efs and restore but its not always as straight forward to restore it. You would also need to flash a new bootloader and modem.
Did you make a nandroid backup of your previous firmware? If not then you cant try that.
The only other way you can try is to flash a 5.1.1 custom rom. Again you will lose imei. So efs backup is important. You would also need to flash BL and modem again.
There are roms based on lollipop which is a much safer way to revert back, try one of them.
Overall i wouldnt try it bit its up to you. If you do and you find a way to do it let me know.

You cant downgrade after 4xxxx firmware mate. After updated bootloader your stuck on mm.
There are ROMs based on 5.1.1. But because you flashed 4xxxx firmware you cant downgrade. All lollipop firmwares are 3xxxx

I am not sure if the rom you use is using the latest base.
If that is the case, the BTU/XEU has not updated yet... you can use XEF which is the French version. That has latest base and should flash.

Also you don't reported which Odin version you was using. you need Odin 3.13.1 to flash Oreo firmware.
And you can't downgrade the bootloader. So you need to flash a stock Rom with same or newer bootloader like already installed.
Don't be afraid to hit the "Thanks" button if someone helped you. It don't hurts

I used the latest odin and now just trying to find the latest firmware , I'm downloading XEF the French firmware that the previous comment mentioned
I would use the stock firmware with the manufacturer CSC of the device.
And there is a log window in Odin that shows logs of the flash process. There showing often useful informations. So next time make a screenshot with this logs and post it here

I got a customer who wants to downgrade from Android 10 to 8. I know Samsung has anti-downgrade protection and you can't flash older firmware using Odin.
What about rooting the phone first though and flashing the Android 8 firmware using TWRP? Wouldn't that work?

My phone is already rooted and do you have any guide how can I flash complete firmware through twrp with bootloader. Actual problem is bootloader which can't initialize previous version of modem. I have downgraded modem but it does not pick IMEI.

You'd have to flash system, vendor and a kernel that can run Android 8. Just flashing the firmware straight up won't work

I don't need to downgrade bootloader, just need to flash the ROM which includes system, vendor and a working kernel.
I'm speaking strictly about running Android 8, not downgrading. So this method of downgrading to Oreo probably won't help you on your problem

I think combination file might downgrade with re partition
