hi there.

we all know that new build are coming with new security and if i cannot do my job with octoplus frp or youtube videos it`s an idea to downgrade.

What are the conditions with smartphones with new androids. for example is there a rule i cannot downgrade android 8 with 7?/at all with previous big version/

now i have one p20 lite and one p30

this security feature is called anti-rollback, and you'll have to do some research as to if a certain mode has this or not
both devices you mentioned don't come pre-installed with anything below android 8 and 9 respectively, you can't possibly downgrade either device to android 7

That would depend on your variant. If you're flashing an OTA / SD card format firmware then those don't play so well with downgrading

Yes, you can downgrade to a firmware with the same bootloader version, not lower.
