No, if the stock update is for your device, then it's compatible with it, because the company released it for you, any android phone is upgradable but the phone's company just remove support of its old devices.
I'm using galaxy s2 and running nogut 7.1.1

downgrading Lenovo Tab 7 TB-7304I (Android 7)

i bought Lenovo Tab 7 Essential TB-7304I - 1GB RAM with Android 7.0 (Nougat) pre-installed. the device is too slow and i believe that the 1GB ram cannot handle Android 7.0 at all!
i searched for lower Android version (6 or even 5) to install it on this device with no success.
maybe becuase i'm not familiar with Android anyone can help me finding Android 6.x or Android 5.x that can be installed on Lenovo Tab 7 Essential TB-7304I. Or the available CUSTOM ROM if any also i would appreciate if you can suggest a page for the downgrading steps
Anyone can help!!!
No one can help me with this issue??

Any update please
Have you unlocked bootloader and installed custom recovery?
There are no custom roms for this device. Even 4pda has nothing and this tablet is popular amongst the Russians due to the price.

Amlogic CX S819 CFW

It's because Amlogic never released the updated SDK for that chipset. That's why it's nearly impossible to do it, unless you know porting and can scrape off things from similar chipsets.

Need help regarding One UI 2.0 on A10

I have a Samsung Galaxy J7 with non-original screen and after updating it to android Pie it's touchscreen stopped working, after going through a complicated process i managed to downgrade it. I have another device; Samsung A10 with non original screen. As android 10 is already available on A10, i'm afraid to upgrade it because of my past experience. Anyone hear who is using fake/non-original screen and have upgraded to pie?

You can upgrade it to Android 10.
In case, your touchscreen doesn't work, you can downgrade to android 9 on A10 via odin mode.

For A10, android 10 and android 9 use the same binary version, which is version 3.
Therefore, you can downgrade to the latest release of android 9.
The binary version can be obtained from the bootloader's filename found in stock firmware.
The bootloader's filename general format is as follows: BL_A105XXXU3XXXX
U3 is the binary version.
You can compare before you try to flash
