    Dear all,

    I want to know that it is possible to OTA update from Marshmallow to Oreo without updating Nougat using adb sideload.
    As I know the Marshmallow is Non-A/B system, but the Oreo is A/B system. Right?
    And I want to know the mechanism about this update.

    Thanks

    If it doesn't work you will know it sooner or later ;)

    Btw, what device do you have?

    I guess the mechanism of the update, if available, will depend on the particular make/model of phone or tablet you've actually got there.

    Thank you for your answer.:)

    Why aren't you happy with Marshmallow? Nougat and Oreo are significantly larger and there is no warranty that they will make your device run better.

    Where are you going to get an OTA to Oreo for the Note 2?

    If an update is actually delivered over the air to your phone via the system update menu then it will be compatible. But those do not skip over updates: they will offer you each update in sequence until you reach the most recent. I'm also pretty sure that the Note 2 doesn't have an official update to Marshmallow, never mind Oreo, so despite you asking about OTA I don't think that's what you meant.

    If, as I suspect, you are using a custom ROM, then it's just a matter of installing a different custom ROM. Take a Nandroid backup first in case the new ROM doesn't work or you just don't like it. Back up all of your data too as you will need to do a factory reset during the install.

    If you meant "I've seen OTA update files for other Samsung Notes and wondered whether i could use one of those", the answer is "no, you can't".

    So if you tell us a bit more about how you hope to update a Note 2 to Oreo someone might be able to offer more advice.

    And Oreo for a Samsung won't be a/b anyway (and no custom ROM will change the number of system partitions).

    Since the Note 2 was only officially updated to Kitkat, if you are running Marshmallow, it's got to be a custom ROM. From what I can see Nougat seems to be as far as stable ROMs go for the 2 ... LineageOS has one that should work if it matches your model number. You may be currently running LineageOS which does include an updater, that's why you might think it's an OTA.

    I doubt a Note 2 could handle Oreo,

    It's the same for any device: if there is an official update you can use it. If there is a custom ROM then you can try it, but some are better than others so always make sure you know how you are going to change back if it doesn't work out, and have that plan sorted before you install a new ROM.

    The only thing to add is that both the availability and the quality of custom ROMs depends on what phone you have. Some have none at all, some have many options.

    That's not quite what you originally asked: you asked whether you could OTA directly between the two versions.

    The big difference with the s7 is that it's new enough that there is an official Oreo for it. So you could OTA update to Oreo, but don't be surprised if you have to perform a series of updates to get there (which might mean updating to Nougat on the way, even if you immediately update again). But if you keep just accepting updates until there are no more you will end up on the most recent version released for your phone. It might do it in one step by now (i.e. they might withdraw some of the intermediate ones and replace with a big one that does the full update), but I don't know.

    If you really want to do it in one step, the way to be sure is to download the latest software for your model (full model number, not just S7) from Sammobile.com and install that. You'll need a computer and some Samsung software (Odin I think, but I'm not a Samsung expect), and I don't know whether this will wipe the phone or not (I'd back up anyway; if you are jumping 2 major versions in one step I wouldn't rule out needing a reset to clear niggles due to incompatible data). Plenty of people here know that process anyway even if i don't. But as that is a full firmware build it will replace everything, and hence it makes no difference what firmware you are starting from.

    For the S7 to bring it up several versions in one step, it would probably be best to use Samsung's Smart Switch emergency recovery option, which does pretty much the same thing as flashing it with Odin. Smart Switch is a little safer because it verifies the IMEI and serial numbers before downloading the firmware. Takes the guesswork out of it for you.
