How to get O2 sourced S9 to Android 10

I have a Samsung Galaxy S9 running Android 8.0.0 / G960FXXS2BRK3

It was acquired through an O2 contract but I've since moved to Sky.

I did allow it to upgrade once to Android 9 but this broke call recording, which is very useful to me, so I rolled it back. It was a PITA!

Now A10 is available for this phone but I'm just being offered A9 by the software.

My question is whether I must first upgrade to A9 then afterwards I'll be offered A10? The USB port is broken so there is no going back should I end up stranded on A9.

Software version the OS is offering me: G960FXXU2CSC8 / G960FOTF2CSC6 / G960FXXU2CSC1

@mark45623 

OTA updates have to be done sequentially so yes, you need to be on 9 before you can get 10.

I'm not guaranteeing you will get 10 though as you have previously flashed firmware, you may have broken the update cycle.

I'd get the usb port fixed (the part costs £8) so you can flash 10 yourself.

Edit for spelling

Thanks for the tip, I took the plunge and all the updates went through ok and I'm now on G960FXXSBETG8

Alas call recording no longer records the remote person's speech so I've ordered the new components and will get the USB port working again so I can downgrade. I had read somewhere that this was working in A10 but so much for my research!

You could try a call recording app @mark45623 ?

I've been using ACR for years, invaluable when speaking to someone like an accountant that machine guns you with info that you cannot possibly absorb at the time.

Any I've downloaded this code now so just waiting on the parts. Hopefully I do a better job of getting the back off than I did with my missus' S7 (broke the glass!)

Luck is in short supply it seems as Android changes the bootloader as it upgrades and a secure bootloader feature prevents downgrades to it.

So this means I'm stranded on Android 10 and call recording now can only record my side of the call so after 9 years of recording calls, which has been invaluable along the way, it's gone never to return to this phone. I am gutted. Damn.
