Rooting and rom queries, any help?

Rooting and rom querries

Hello Guys! I have some confusions regarding rooting and roms. I will be very thankful if someone answers them. Few questions that I have in mind are
1. Is there option available to backup stock rom without rooting device?
2. Is rom backup after rooting (without installing any other custom rom) 100% pure stock rom backup? and can this rom backup be used to unroot your device to original state to claim warranty?
3. Is it mandatory to install any custom rom after rooting or can device continue to work on your original rom?

Questions may seem pretty basic but I am new to this rooting and I couldn't find answers anywhere. Please do reply. I use Lenovo Tab S8-50 if it's of any help. Thanks in advance.

Hi

1. No you cannot save a backup of your stock rom. You can however, (if available) download stock rom from Lenovo. Example, I use Sammobile to download my OEM software, and flash with Odin. You may or may not, have that available to you.

2. No, refer to answer 1 above.

3. No, you can simply just enjoy root access, and the many apps that utilize it.

Hope this helps!
