How to upgrade from rooted Andtoid 9 tab s6 rooted with odin but pc no longer availab

[MadusDogusUK]

Ive rooted my SM-T860 using a Windows 7 laptop/Odin and Magisk before the Android 10 update. I no longer have the laptop.
Can anyone advise how I update to Android 10 without a PC if its even possible with my Tab rooted.
Is Mobile Odin an option?
I don't have TWRP installed only stock recovery.
Any replies are gratefully appreciated.

I'm thinking I should have used a different root method and installed TWRP, but I didn't, thanks in advance guys.
Hope everyone is doing ok.

You are going to need a PC. You will have to Odin back to stock at the very least.

Try FlashFire app from Playstore. If you are rooted it is only way to flash ROM without PC.

I brought mobile Odin a few years back, with no TWRP installed would mOdin or flashfire work ok do you think? Thank you for your help, I seriously appreciate it.

Thanks for the reply, why would I have to go back to stock first?
I really regret the root method I chose and ideally I would love to have TWRP and pass all device security checks etc.
I'm just really anxious and nervous to make a mistake that makes my device unusable :/

I miss kingoroot/towelroot/iRoot etc lol
