Sorry in advance if this is a dumb question but I have an old OP5 sitting in a drawer that I'm not using anymore- it's already rooted and running a custom Android 6 ROM that I had flashed.
I was going to give it to a friend but I wanted to flash an Android 10 ROM on it for him before handing it over (he doesn't know how to do this stuff).
I wanted to know if I can wipe the phone, flash a newer version of TWRP and then either OOS 10 or a custom Q ROM, or if I have to flash it to OOS 6, then 7, 8, 9 before I can put an Android 10 ROM on it.
I vaguely remember going 2 versions up on this device before (possibly back in the lollipop era) and if I recall correctly I had to flash the next Android version before flashing to the version after that in order for the custom ROM to work, but it's been a long time. Thanks in advance for any wisdom you can offer.
